Background
Obesity, sarcopenia, and sarcopenic obesity are increasingly prevalent in older adults and negatively affect health-related quality of life (HRQOL). While EuroQol-5 Dimension and Short Form-36 Health Survey are widely used HRQOL measures, they have limitations in sensitivity and cultural relevance. In contrast, the Health-related Quality of Life Instrument with 8 Items (HINT-8) is a preference-based instrument developed specifically for the Korean population, offering finer discrimination of physical, emotional, and social health domains.
Methods
This study analyzed data from 1,387 older adults (≥65 years) from the 2023 Korea National Health and Nutrition Examination Survey. Obesity was defined as body mass index ≥25 kg/m 2 , sarcopenia by Asian Working Group for Sarcopenia 2019 criteria, and sarcopenic obesity as having both conditions. Multiple linear regression was used to examine their independent effects on HRQOL, adjusting for potential confounders.
Results
Of the participants, 54.2% were classified as normal, 34.9% as obese, 9.8% with sarcopenia, and 1.1% with sarcopenic obesity. All three conditions were significantly associated with greater difficulty in stair climbing: obesity (B=0.223, P<0.001), sarcopenia (B=0.242, P<0.001), and sarcopenic obesity (B=0.338, P=0.048). Sarcopenia was also linked to impaired working ability and higher total HINT-8 scores. Sarcopenic obesity was associated with greater pain. And obesity was linked to slightly lower depression scores.
Conclusion
Obesity, sarcopenia, and sarcopenic obesity negatively impact HRQOL in older adults. Early detection and intervention are essential to improve quality of life and extend health-adjusted life expectancy.

Effectiveness of an informal home care support intervention program to reduce loneliness and improve quality of life among lonely community-dwelling older adults: a feasibility study
Ahmad Kousha, Elham Lotfalinezhad, Haidar Nadrian, Karen Andersen-Ranberg, Shannon Freeman, Fatemeh Barati, Hasan Mosazadeh, Mina Hashemiparast, Mohammed Asghari Jafarabadi, Ahmad Sohrabi, Mohammad Reza Honarvar
Korean J Fam Med 2025;46(3):185-194.   Published online June 7, 2024
DOI: https://doi.org/10.4082/kjfm.23.0269
Background
Establishing cost-effective informal care services for lonely older adults living at home in developing countries can be an innovative approach for improving their well-being. This study investigated the effectiveness of an informal home care support intervention program (HoSIP) reducing the loneliness and improving quality of life of lonely community-dwelling older adults.
Methods
This quasi-experimental pre-post study employed a non-randomized control group design with a 12-week intervention period and three follow-up points at the end of the HoSIP. Questionnaires were used to measure feelings of loneliness (20-item UCLA Loneliness Scale), quality of life (Control, Autonomy, Self‐Realization and Pleasure Scale), general health (12-item General Health Questionnaire), social network (six-item Lubben Social Network Scale), social support (12-item Multidimensional Scale of Perceived Social Support), and self-care ability (17-item Self-care Ability Scale for the Elderly). Repeated-measures analysis of variance was used to gauge the effect of the intervention program over time and in comparison to the control group. Data analyses were performed using the IBM SPSS Statistics software (IBM Corp.).
Results
We found a significant relationship between the outcome variables, including feelings of loneliness (P<0.001) and quality of life (P<0.001), at different stages of measurement. Despite the positive feasibility results, the implementation of the HoSIP faced challenges due to a lack of facilities (e.g., place restriction for holding educational classes, educational facilities like computers, video projector, and whiteboard at daycare center) and the absence of supporting organizations.
Conclusion
Utilizing the existing capabilities of older adults to provide online and face-to-face care services can be a cost-effective way to improve their quality of life and reduce loneliness. The process of facilitating such informal care services for lonely older adults should be managed by either governmental or non-governmental organizations to reduce the rate of social isolation among this vulnerable population.

Association of lipoprotein(a) with progression of coronary artery calcification: retrospective longitudinal study
Anna Lee, Hyun-Min Koh, Ji-Yong Jang, Hye-Rang Bak, Hye-Jin Jang, Jun-Young Huh, Nak-Gyeong Ko
Korean J Fam Med 2025;46(3):176-184.   Published online May 22, 2024
DOI: https://doi.org/10.4082/kjfm.23.0108
Background
Atherosclerotic cardiovascular disease (ASCVD) is a major health concern, and lipoprotein(a) (Lp(a)) is an independent risk factor. However, there is limited evidence regarding Lp(a) and the risk of ASCVD in Asian populations. This study aimed to assess the predictive value of changes in coronary artery calcification (CAC) for ASCVD risk associated with Lp(a) level.
Methods
Participants (n=2,750) were grouped according to their Lp(a) levels, and the association between Lp(a) and CAC progression was examined. CAC progression was defined as the occurrence of incident CAC or a difference ≥2.5 between the square root (√) of baseline and follow-up coronary artery calcium scores (CACSs) (Δ√transformed CACS). To adjust for differences in follow-up periods, Δ√transformed CACS was divided by the follow- up period (in years).
Results
Over an average follow-up of 3.07 years, 18.98% of participants experienced CAC progression. Those with disease progression had notably higher Lp(a) levels. Higher Lp(a) tertiles correlated with increased baseline and follow-up CACS, CAC progression (%), and Δ√transformed CACS. Even after adjustment, higher Lp(a) levels were associated with CAC progression. However, annualized Δ√transformed CACS analysis yielded no significant results.
Conclusion
This study demonstrated an association between elevated Lp(a) levels and CAC progression in a general population without ASCVD. However, longer-term follow-up studies are needed to obtain meaningful results regarding CAC progression. Further research is necessary to utilize Lp(a) level as a predictor of cardiovascular disease and to establish clinically relevant thresholds specific to the Korean population.

Relationship between social participation and cognitive impairment in low-educated older adults based on Indonesian Family Life Survey-5
Jayanto Nanda Putra, Yuda Turana, Yvonne Suzy Handajani
Korean J Fam Med 2025;46(3):170-175.   Published online May 21, 2024
DOI: https://doi.org/10.4082/kjfm.23.0134
Background
The increasing older adult population requires attention in terms of education and health, as higher education levels contribute to cognitive reserve and may protect against age-related cognitive impairment. Cognitive reserve is an individual’s cognitive flexibility in using cognitive functions affected by brain aging, neurological diseases, and injury. Indonesia has a high prevalence of low-educated older adults, which strongly correlates with progressive cognitive impairment. Identifying risk factors for cognitive decline in this population is crucial. This study determines the factors affecting cognitive impairment in low-educated older adults using cross-sectional data from the Indonesian Family Life Survey-5.
Methods
This descriptive study analyzed 2,313 low-educated older adults ≥60 years old. Univariate and bivariate analyses were used to describe the sample and identify the relationships between categorical variables. Logistic regression identified the most significant factor affecting cognitive impairment.
Results
The prevalence of cognitive impairment in low-educated older adults is 22.6%. The chi-square test revealed significant relationships between those who are aged 75 years, a status other than married, female, living in rural areas, and not participating in social activities. Age is the most prominent factor affecting cognitive impairment in such adults (P<0.001; adjusted odds ratio, 3.232; 95% confidence interval, 2.500–4.180).
Conclusion
Cognitive impairment in the aforementioned adults is associated with being ≥75 years old, being a status other than married, being female, living in rural areas, and not participating in social activities. After controlling other variables, low-educated older adults who participated in at least ≥1 social activity in the last 12 months experienced cognitive impairment 0.64 times compared to those who did not participate in social activities.

Background
Circadian misalignment is associated with metabolic syndrome. This study aimed to examine the association between circadian rhythm-disturbing factors and metabolic syndrome.
Methods
We used data from the 7th and 8th Korea National Health and Nutrition Examination Survey conducted between 2016 and 2020, which surveyed 16,253 individuals. Circadian rhythm-disturbing factors were defined as follows: sleep duration outside the reference group (6–8 hours), irregular breakfast, shift work, and physical inactivity. The adjusted odds ratio (aOR) for metabolic syndrome was calculated based on the number of circadian rhythm-disturbing factors present in adults over the age of 19 years.
Results
Among a total of 16,253 participants (mean age 48.2±15 years), metabolic syndrome was found in 5,237 participants (29.3%). The participants were classified into three categories based on the number of circadian rhythm-disturbing factors as follows: 2,627 (15.6%) did not have any factors, 6,406 (38.13%) had one factor, and 7,220 (46.3%) had two or more factors. Participants with a single circadian rhythm-disturbing factor were 21% more likely to have metabolic syndrome (aOR, 1.21; 95% confidence interval [CI], 1.08–1.36), and participants with two or more factors were 27% more likely to have metabolic syndrome (aOR, 1.27; 95% CI, 1.12–1.43).
Conclusion
Circadian rhythm-disturbing factors were significantly associated with the prevalence of metabolic syndrome in Korean adults. This finding has potential clinical implications for maintaining circadian rhythms by avoiding certain factors to prevent metabolic syndrome. Further studies are required to confirm these findings.

Comparing mobile-based to group-based education for weight reduction in a developing country: a randomized study
Hourvash Haghighinejad, Forough Sedaghat, Marzieh Akbarzadeh, Mahtab Jafari
Korean J Fam Med 2025;46(3):152-161.   Published online May 21, 2024
DOI: https://doi.org/10.4082/kjfm.23.0144
Background
This study compared the impact of Short Message Service (SMS)-based education with traditional group-based education and the control group on body mass index, weight, and lifestyle in obese and overweight patients in a limited-resource country. It also compared the direct financial costs between the two intervention groups.
Methods
In this controlled randomized educational study, 90 overweight or obese adults from four family physician clinics in Shiraz, Iran were randomly allocated to three training groups: SMS-based education, group-based education, and a control group. The participants’ weight, body mass index (BMI), and waist circumference were measured at baseline, and the Physical Activity Scale questionnaire was completed. Group-based training was conducted in 1-hour weekly sessions. The SMS group received a text message each morning. The control group received routine care from a family physician. The intervention lasted 12 weeks. All participants were re-examined for the studied variables. Additionally, the direct costs were estimated, calculated, and compared.
Results
The mean weight, BMI, and waist circumference changed significantly after 3 months compared to baseline in each group. The mean weight change differed significantly among the three groups (P-value=0.04), and the mean BMI changes were near significant (P-value=0.06). A post hoc comparison of changes in weight and BMI showed a significant difference between the control and SMS groups. SMS education incurred much lower costs for patients and healthcare services than group-based education.
Conclusion
The study showed that SMS is an effective and cost-saving educational method for weight loss compared to group-based education, especially in developing countries.

Background
Interest in healthy aging has grown with the increase in the older population. Nutritional intake is crucial in frailty. Therefore, we aimed to investigate the relationship between frailty and multivitamin and mineral supplements (MVMS), which can easily provide micronutrients.
Methods
The Korea National Health and Nutrition Examination Survey (KNHANES) conducted from 2018 to 2019 included 3,395 adults aged ≥65 years. Of these, 1,511 who did not consume dietary supplements (DS, non-DS group) and 415 who took MVMS (MVMS group) were included in the study. We modified Fried’s definition of frailty to fit the KNHANES data. Using multivariate logistic regression, we examined the association between MVMS use and frailty, which varied with satisfaction with total energy intake. Additional subgroup analyses were performed based on age, sex, and income.
Results
MVMS reduced most micronutrient deficiencies compared to obtaining nutrients solely through food. The overall analysis revealed no association between MVMS use and frailty (odds ratio [OR], 0.75; 95% confidence interval [CI], 0.52–1.09). However, a subanalysis revealed that participants with a low income (≤25%) who took MVMS had decreased odds for frailty (OR, 0.55; 95% CI, 0.35–0.88) compared with the non-DS group. Furthermore, a significant association between using MVMS and frailty was confirmed in the group with low income and energy intake below the recommended daily allowance, with a low OR of 0.52 (95% CI, 0.30–0.90).
Conclusion
MVMS use was significantly associated with frailty among the low-income and low-daily energy intake groups.

Association of body image distortion with smartphone dependency and usage time in adolescents: a cross-sectional Korean Youth Study
Haein Cho, Junhee Park, Dagyeong Lee, Dong Wook Shin
Korean J Fam Med 2025;46(2):98-106.   Published online May 22, 2024
DOI: https://doi.org/10.4082/kjfm.23.0159
Background
Adolescent dependency on smartphones is the highest among all age groups. Adolescents can be influenced to evaluate their body image by popular ideals about beautiful bodies via smartphone content, which can cause body image distortion. This study aimed to examine the association between body image distortion and smartphone dependency and the duration of smartphone usage among Korean adolescents.
Methods
This study used data from the 16th Korean Youth Risk Behavior Web-Based Survey (2020), and included 42,981 participants, who were grouped according to self-reported duration of smartphone usage and smartphone dependency, as measured by a questionnaire. Body image distortion is defined as an exaggerated subjective body image compared to the actual body image. Multivariable-adjusted logistic regression was used to determine the odds ratios (ORs) with 95% confidence intervals (CIs) of body image distortion on smartphone dependency and usage time after adjusting for various factors related to body image distortion.
Results
Among the 42,981 participants, both moderate and high levels of smartphone dependency were associated with body image distortion in boys (moderate: adjusted OR [aOR], 1.11; 95% CI, 1.01–1.22; high: aOR, 1.18; 95% CI, 1.05–1.32) and girls (moderate: aOR, 1.14; 95% CI, 1.05–1.23; high: aOR, 1.30; 95% CI, 1.18–1.42) compared to the low-level dependency group. However, no significant association was found between smartphone usage duration and body image distortion.
Conclusion
Our study demonstrated that moderate to high levels of smartphone dependency are associated with body image distortion in adolescents. Therefore, it is necessary to establish strategies for checking and managing adolescents’ smartphone dependence.

Eun Ji Han, Eun Ju Park, Sae Rom Lee, Sang Yeoup Lee, Young Hye Cho, Young In Lee, Jung In Choi, Ryuk Jun Kwon, Soo Min Son, Yun Jin Kim, Jeong Gyu Lee, Yu Hyeon Yi, Young Jin Tak, Seung Hun Lee, Gyu Lee Kim, Young Jin Ra
Korean J Fam Med 2025;46(2):92-97.   Published online July 5, 2024
DOI: https://doi.org/10.4082/kjfm.23.0151
Background
Skipping breakfast is associated with an increased risk of chronic inflammatory diseases. This study aimed to examine the association between breakfast-eating habits and inflammation, using high-sensitivity C-reactive protein (hs-CRP) as a marker.
Methods
A total of 4,000 Korean adult males with no history of myocardial infarction, angina, stroke, diabetes, rheumatoid arthritis, cancer, or current smoking were included. Data from the 2016–2018 Korea National Health and Nutrition Examination Survey were used for analysis. The frequency of breakfast consumption was assessed through a questionnaire item in the dietary survey section asking participants about their weekly breakfast consumption routines over the past year. Participants were categorized into two groups, namely “0–2 breakfasts per week” and “3–7 breakfasts per week”; hs-CRP concentrations were measured through blood tests.
Results
Comparing between the “infrequent breakfast consumption (0–2 breakfasts per week)” and “frequent breakfast consumption (3–7 breakfasts per week)” groups, the mean hs-CRP was found to be significantly higher in the “infrequent breakfast consumption” group, even after adjusting for age, body mass index, physical activity, alcohol consumption, systolic blood pressure, blood pressure medication, fasting blood glucose, and triglycerides (mean hs-CRP: frequent breakfast consumption, 1.36±0.09 mg/L; infrequent breakfast consumption, 1.17±0.05 mg/L; P-value=0.036).
Conclusion
Less frequent breakfast consumption was associated with elevated hs-CRP levels. Further large-scale studies incorporating adjusted measures of daily eating patterns as well as food quality and quantity are required for a deeper understanding of the role of breakfast in the primary prevention of chronic inflammatory diseases.

Association between mothers’ working hours and metabolic syndrome in children and adolescents: data from the Korea National Health and Nutrition Examination Survey, 2016–2020
Myoung-hye Lee, Joo-Eun Jeong, Hoon-Ki Park, Hwan-Sik Hwang, Kye-Yeung Park
Korean J Fam Med 2025;46(2):84-91.   Published online May 8, 2024
DOI: https://doi.org/10.4082/kjfm.23.0157
Background
Prevention and management of metabolic syndrome (MetS) during childhood are crucial. Recently, obesity among children and adolescents has increased with an increase in mothers’ working hours. The present study was conducted to determine the relationship between mothers’ working hours and MetS in their children.
Methods
Data from the 2016–2020 National Health and Nutrition Examination Survey were used, and 2,598 children and adolescents aged 10–18 years were included. Logistic regression analysis was conducted to confirm the association between MetS and mothers’ working hours for each risk factor. Linear regression analysis was conducted to confirm the association between mothers’ working hours and the number of risk factors for MetS.
Results
Abdominal obesity in children was higher when the mothers’ working hours were 53 hours or more (odds ratio [OR], 2.267; 95% confidence interval [CI], 1.21–4.25). In the trend analysis, the OR of children’s abdominal obesity increased significantly as mothers’ working hours increased (P-value <0.05). Additionally, sex-stratified analysis revealed a significant trend between maternal work hours and the presence of MetS in female children (P=0.016). The adjusted OR of the presence of MetS in female children with mothers working 53 hours or more weekly was 6.065 (95% CI, 1.954–18.822).
Conclusion
Mothers’ working hours were highly correlated with the risk of abdominal obesity in their children. The OR of the presence of MetS significantly increased in female children with mothers having longer working hours compared with those with stay-at-home mothers.

Health information quality of online newspaper articles in Korea
Hangyeol Lee, Seung-Won Oh
Korean J Fam Med 2025;46(2):77-83.   Published online March 7, 2024
DOI: https://doi.org/10.4082/kjfm.23.0197
Background
The Web is an important source of health information, but the quality of such online information is highly variable. This study evaluates the quality of health articles published on Naver News, Korea’s most popular portal, using the Health Information Quality Assessment Tool (HIQUAL).
Methods
We collected 712 health-related articles published on Naver News from May 1 to 7, 2023. After applying exclusion criteria, we selected 116 articles for analysis. Two clinicians independently assessed the quality of these articles using the HIQUAL, which scores articles based on five domains: “reliability,” “usefulness,” “understandability,” “sufficiency,” and “transparency.”
Results
Overall article quality was generally considered recommendable (mean±standard deviation: 7.52±2.00). “Usefulness,” one item of “reliability,” and “understandability” were the three items with the highest levels of satisfaction. “Sufficiency” criteria for costs, risks, and benefits received low scores. Quality scores for articles focused on health risk factors and intervention showed a statistically significant difference.
Conclusion
While the overall quality of health information in Korean online newspaper articles is acceptable, room for improvement remains in some areas, particularly with regard to the fair presentation of costs, risks, and benefits. The study highlights the need for ongoing quality improvement and evaluation initiatives for online health information.

Low serum creatinine as well as high serum creatinine is associated with prognosis of patients with cancer in end-of-life
Yoo Jeong Lee, Soon-Young Hwang, Su Hyun Kim, Youn Seon Choi
Korean J Fam Med 2025;46(2):70-76.   Published online October 27, 2023
DOI: https://doi.org/10.4082/kjfm.23.0116
Background
The prognosis of end-of-life patients is challenging, and clinicians have attempted to predict survival more accurately. High serum creatinine (sCr) levels are associated with lower survival rates in patients with various cancers; however, low sCr levels are commonly expected in patients with terminal cancer because of muscle wasting and malnutrition. Therefore, we investigated the prevalence of low and high sCr levels and their association with survival duration in patients with terminal cancer in a palliative care unit.
Methods
We analyzed the medical records of 280 patients admitted to a palliative care unit. Patients were divided into low (<0.5 mg/dL), normal (0.5–1.2 mg/dL), and high (>1.2 mg/dL) sCr groups. Kaplan-Meier survival curves using sCr levels were plotted and compared using the log-rank test. Using stepwise selection, a multivariable Cox proportional hazards model was used to identify the significant prognostic factors.
Results
The median survival durations in the high-, low-, and normal-sCr groups were 9.57 days, 22.26 days, and 27.51 days, respectively. Multivariable Cox proportional hazard model identified that males (hazard ratio [HR], 1.81; 95% confidence interval [CI], 1.16–2.85), poor performance status (HR, 3.43; 95% CI, 1.12–10.54), total parenteral nutrition use (HR, 1.84; 95% CI, 1.09–3.1), high sCr (HR, 2.74; 95% CI, 1.52–4.94), and low sCr (HR, 1.22; 95% CI, 1.07–1.43) were significantly associated with a shorter survival time.
Conclusion
Low and high serum creatinine levels were significantly associated with poor survival in patients with cancer at the end-of-life stage. Therefore, readily available and simple biomarkers may help plan advanced care in palliative care settings.

Testing the reliability and validity of the Korean version of the Pittsburgh Sleep Quality Index using Fitbit devices: a cross-sectional analysis
Si-Yeon Lee, Ja-Eun Choi, Ji-Won Lee, Yaeji Lee, Jae-Min Park, Kyung-Won Hong
Korean J Fam Med 2025;46(1):42-47.   Published online April 22, 2024
DOI: https://doi.org/10.4082/kjfm.23.0166
Background
Sleep disorders and insomnia are prevalent worldwide, with negative health outcomes. The Pittsburgh Sleep Quality Index (PSQI) is a widely used self-report assessment tool for evaluating sleep quality, comprising seven subdomains. The Korean version of the PSQI (PSQI-K) has been tested for reliability and validity in small sample sizes but lacks large-scale validation using objective measures.
Methods
This study was conducted with 268 Korean adults attending health check programs. Participants completed the PSQI-K questionnaire and wore Fitbit devices (Fitbit Inc., USA) to ascertain sleep parameters. Reliability was analyzed using the Cronbach’s α coefficient, and construct validity was determined through factor analysis. Criteria validity was assessed by correlating their index scores with Fitbit sleep parameters. We identified the optimal cutoff for detecting sleep disorders.
Results
The Cronbach’s α coefficient was 0.61, indicating adequate internal consistency. Factor analysis revealed three factors, explaining 48.2% of sleep quality variance. The index scores were negatively correlated with Fitbit sleep efficiency, total sleep time, and number of awakenings (P<0.05). The optimal cutoff point for identifying sleep disorder groups was ≥6.
Conclusion
The PSQI-K demonstrated good reliability and validity when correlated with Fitbit sleep parameters, offering a practical screening tool for identifying sleep disorders among Korean adults. Cutoff scores can help identify patients for sleep interventions. However, further large-scale studies are required to validate these findings.

Association between obstructive sleep apnea and glaucoma
Yoonchae Zoh, Jae Moon Yun
Korean J Fam Med 2025;46(1):35-41.   Published online March 25, 2024
DOI: https://doi.org/10.4082/kjfm.23.0162
Background
Obstructive sleep apnea (OSA) and glaucoma are major global health challenges. However, the probable association between them is yet to be fully elucidated. This study aimed to investigate the association between OSA and glaucoma.
Methods
Data for this cross-sectional study were obtained from the eighth Korea National Health and Nutrition Examination Survey (2019–2021). From among 9,495 individuals who completed the STOP-Bang questionnaire on OSA (for those aged ≥40 years) and provided their glaucoma prevalence/intraocular pressure (IOP) data, 8,741 were selected for glaucoma prevalence analysis. A total of 754 individuals aged 80 years or older or those with missing confounding variable data were excluded. A separate subgroup of 8,627 individuals was selected for IOP analysis after excluding 114 individuals who use glaucoma eye drops. The study employed linear and logistic regression analyses with Stata/MP ver. 17.0 (Stata Corp., USA) to understand the relationship between the risk of OSA assessed using the STOP-Bang score and key glaucoma indicators, adjusted for confounders. Statistical significance was set at a P-value <0.05.
Results
The average±standard deviation [SD] age of the glaucoma prevalence study group was 56.59±10.48, and 42.98% were male. Notably, every unit increase in the STOP-Bang score was associated with a greater risk of glaucoma (odds ratio, 1.097; P=0.044). In the IOP subgroup, the average±SD age was 56.49±10.45 years, with 42.88% being males. The linear regression showed a statistically significant relationship between the STOP-Bang score and IOP after adjusting for confounding variables (β=0.171, P<0.001).
Conclusion
Our findings revealed a significant positive association between OSA risk, as measured using the STOP-Bang score, and both the likelihood of glaucoma and high IOP.

Changes in the prevalence of metabolic syndrome before and after the COVID-19 pandemic according to household income levels
Hyunjung Kang, Dagyeong Lee, Junhee Park, Su-Min Jung
Korean J Fam Med 2025;46(1):27-34.   Published online April 25, 2024
DOI: https://doi.org/10.4082/kjfm.23.0171
Background
Since the World Health Organization’s pandemic declaration in March 2020, Korea has witnessed shifts in lifestyle behaviors, impacting habits tied to socioeconomic status and contributing to metabolic syndrome (MetS). To investigate this issue, the current study aimed to investigate changes in MetS prevalence, particularly based on income levels before and after the coronavirus disease 2019 (COVID-19) pandemic.
Methods
This study used data from the 8th Korea National Health and Nutrition Examination Survey (2019–2020). A total of 6,840 individuals aged 30–65 years were included in this study. Household income was divided into high (≥75th percentile), middle (25–75th percentile), and low (≤25th percentile). A multivariable logistic regression analysis was performed to explore the interaction between this association before and after the COVID-19 pandemic.
Results
A statistically significant difference was found in the prevalence of MetS before and after the COVID-19 pandemic (26.7% to 30.2%, P=0.001). These changes differed based on income levels. The increase in the prevalence of MetS was statistically significant in the low- and high-income groups but not in the middle-income group (low: 8.0%p increase [P=0.039], middle: 1.0%p increase [P=0.522], high: 6.4%p increase [P<0.001]). The interaction between household income and the COVID-19 pandemic on MetS was statistically significant (P for interaction=0.032).
Conclusion
This study revealed that P for interaction between household income, MetS, and the period before and after the COVID-19 pandemic was significant. Changes in physical activity and eating habits during the COVID-19 pandemic may have contributed to these differences.

Wonyoung Jung, Seung-Won Oh, Se-Hong Kim, Soo Young Kim
Korean J Fam Med 2025;46(1):20-26.   Published online November 12, 2024
DOI: https://doi.org/10.4082/kjfm.24.0115
Background
Despite the increase in daily alcohol intake in recent decades and the implementation of national health screenings, effective management strategies for alcohol consumption remain outdated. This review evaluates intervention studies on screening and behavioral counseling for unhealthy alcohol use, with the aim of enhancing the effectiveness of interventions and improving health outcomes.
Methods
On the basis of the GRADE (Grading of Recommendations Assessment, Development, and Evaluation)- ADOLOPMENT framework, systematic reviews and randomized controlled trials were examined to investigate the effectiveness of screening and counseling interventions in reducing unhealthy alcohol use. Five key questions were generated, and an evaluation and quality assessment of existing systematic reviews and new evidence related to each key question were conducted.
Results
Updating the U.S. Preventive Services Task Force and Cochrane 2018 reviews, we identified five new randomized trials that evaluated screening and counseling interventions for unhealthy alcohol use. For Key Question 2, the sensitivity and specificity of the new screening studies were consistent with those of prior research. Brief interventions were confirmed to reduce alcohol use (Key Question 4a), although additional research is required for a wider array of health outcomes. One study highlighted the benefits of counseling interventions for newborn health indicators in pregnant women (Key Question 4b). No new evidence was found regarding the harms of screening (Key Question 3) or alcohol use reduction interventions (Key Question 5).
Conclusion
This review supports the continued use of brief interventions to reduce alcohol consumption in highrisk groups and highlights the need for culturally tailored research in Korea.

Tobacco cessation: screening and interventions
Yoo-Bin Seo, Sang-Wook Song, Sung-Goo Kang, Soo Young Kim
Korean J Fam Med 2025;46(1):12-19.   Published online October 29, 2024
DOI: https://doi.org/10.4082/kjfm.24.0034
Background
Tobacco use has been the leading cause of disease and death in South Korea. Early detection of tobacco use and evidence-based interventions play pivotal roles in facilitating tobacco cessation.
Methods
In accordance with the earlier iterations of the Lifetime Health Maintenance Program (2009) and recent recommendations from the United States Preventive Services Task Force (USPSTF; 2021), two themes were chosen for investigation: the identification of and intervention for tobacco use. The USPSTF recommendations were formulated by conducting an overview of reviews. In this study, literature searches and quality assessments of reviews were conducted.
Results
The findings highlighted the efficacy of physician-led identification and advising in promoting tobacco cessation, with robust evidence supporting the implementation of behavioral and pharmacological interventions. These interventions significantly increased the likelihood of successful cessation compared with usual care. Digital interventions, such as internet- or mobile-based interventions, showed additive effects for quitting.
Conclusion
Identification and targeted interventions are essential for tobacco cessation. By leveraging evidencebased strategies and enhancing access to resources, healthcare providers can empower individuals to achieve successful tobacco cessation and improve overall health outcomes.

Mea’ad Mansour Harahsheh, Tareq Lewis Mukattash, Samah Fawzi Al-shatnawi, Rana Kamal Abu-Farha, Deirdre M. D’Arcy, Anan Sadeq Jarab, Sawsan Hammad Abuhammad
Korean J Fam Med 2024;45(6):346-355.   Published online April 22, 2024
DOI: https://doi.org/10.4082/kjfm.23.0103
Background
This study explored the approaches of Jordanian community pharmacists to identifying and counseling breastfeeding mothers regarding medication usage.
Methods
This cross-sectional study used self-administered questionnaires. A convenience sample (n=381) of Jordanian community pharmacists was recruited through social media. The responses were statistically analyzed using IBM SPSS ver. 25.0 (IBM Corp., USA).
Results
The majority of recruited pharmacists were female (n=329, 86.4%). Asking every woman was Jordanian pharmacists’ preferred approach to identifying breastfeeding women (n=211, 55.4%). The study showed that around one-third of the pharmacists (n=128, 33.6%) reported that they currently experienced queries regarding medication use during breastfeeding on a daily basis. Additionally, the majority (n=325, 85.3%) of pharmacists reported feeling confident, and 67.2% of them (n=256) reported feeling comfortable while giving advice to breastfeeding women. The surveyed pharmacists relied on different resources during their course of practice to answer queries related to medicine usage by breastfeeding mothers.
Conclusion
Community pharmacists have continuous interactions with breastfeeding women. Pharmacists require reliable and updated data access to answer queries related to medication use while breastfeeding.

Background
Sickness presenteeism (SP) refers to the phenomenon where employees attend work while sick, a decision that impacts both their physical and mental well-being and can lead to burnout. This study aimed to determine the prevalence of and factors influencing SP among Thai and foreign teachers following the end of the coronavirus disease 2019 public health emergency of international concern (PHEIC).
Methods
A sample of 400 individuals was analyzed using chi-square tests and logistic regression to obtain odds ratios (ORs) and 95% confidence intervals (CI).
Results
Post-PHEIC, a significant proportion of teachers (51.9%) perceived an increase in their workload, and 62.1% reported having taken health-related leave of absence. The prevalence of SP was high (35.0%). Factors significantly associated with SP (P<0.05) included being younger than 37 years (OR, 1.825; 95% CI, 1.108–3.006), facing monthly financial challenges (OR, 1.627; 95% CI, 1.028–2.575), doing school-related work on holidays (OR, 1.920; 95% CI, 1.180–3.122), and experiencing sleep disturbances owing to work-related stress (OR, 1.910; 95% CI, 1.203– 3.033). No discernible difference existed in SP rates between Thai and foreign teachers.
Conclusion
As a course of action, we recommend the provision of appropriate financial planning resources for teachers. Policywise, school events and activities should be scheduled on working days to ensure that teachers maintain a work-life balance. Additionally, task allocation that caters to individual strengths and limitations can mitigate the effects of SP.

The Effect of Psychological Resilience on Cognitive Decline in Community-Dwelling Older Adults: The Korean Frailty and Aging Cohort Study
Sunwoo Kim, Chang Won Won, Sunyoung Kim, Jung Ha Park, Miji Kim, Byungsung Kim, Jihae Ryu
Korean J Fam Med 2024;45(6):331-336.   Published online March 25, 2024
DOI: https://doi.org/10.4082/kjfm.23.0145
Background
Chronic stress is associated with an increased risk of cognitive impairment and Alzheimer’s disease. This study aimed to assess whether better coping with stress, as assessed using the Brief Resilience Scale (BRS), is associated with slower cognitive decline in community-dwelling older adults.
Methods
This study used 2018/2019 data and 2-year follow-up data from the Korean Frailty and Aging Cohort Study. Of the 3,014 total participants, we included 1,826 participants (mean age, 77.6±3.7 years, 51.9% female) who completed BRS and Korean version of the Consortium to Establish a Registry for Alzheimer’s Disease Assessment Battery and the Korean version of the Frontal Assessment Battery (FAB).
Results
Higher BRS score at baseline was associated with a lesser decline in the Mini-Mental State Examination score over 2 years after adjusting for age, sex, years of education, smoking status, hypertension, diabetes, and depression (B, 0.175; 95% confidence interval, 0.025–0.325) for 2 years, which represents global cognitive function. Other cognitive function measurements (Word List Memory, Word List Recall, Word List Recognition, Digit Span, Trail Making Test-A, and FAB) did not change significantly with the BRS score at baseline.
Conclusion
These findings suggest that better stress-coping ability, meaning faster termination of the stress response, may limit the decline in cognitive function.

Non-Insulin-Based Indices of Insulin Resistance for Predicting Incident Albuminuria: A Nationwide Population-Based Study
Hea Lim Choi, Juyeon Yang, Hye Sun Lee, Ji-Won Lee
Korean J Fam Med 2024;45(6):324-330.   Published online March 25, 2024
DOI: https://doi.org/10.4082/kjfm.23.0138
Background
Studies have shown that incident albuminuria is associated with insulin resistance (IR); however, an IR marker that best predicts the prevalence of albuminuria has not yet been established. This study explored the association between IR and incident albuminuria using various IR indices, including the homeostasis model assessment of IR (HOMA-IR), metabolic score for IR (METS-IR), and triglyceride-glucose (TyG) index, and compared their predictive abilities for the prevalence of albuminuria.
Methods
A total of 4,982 Korean adults from the 2019 Korea National Health and Nutritional Examination Survey were analyzed. The odds of albuminuria were determined using the quartiles of the IR indices. Receiver operating characteristic (ROC) curves were used to calculate the area under the ROC curve and predictability. The cutoff values for albuminuria detection were also computed.
Results
An increase in the quartiles of all three IR indices was associated with incident albuminuria, even after full adjustment for covariates (HOMA-IR: odds ratio [OR], 1.906; 95% confidence interval [CI], 1.311–2.772; P=0.006; METS-IR: OR, 2.236; 95% CI, 1.353–3.694; P=0.002; TyG index: OR, 1.757; 95% CI, 1.213–2.544; P=0.003). The area under the ROC curve for incident albuminuria based on the HOMA-IR, METS-IR, and TyG indices was 0.594 (95% CI, 0.568–0.619), 0.633 (95% CI, 0.607–0.659), and 0.631 (95% CI, 0.606–0.656), respectively. The optimal cutoff values for predicting albuminuria were 2.38, 35.38, and 8.72 for the HOMA-IR, METS-IR, and TyG indices, respectively.
Conclusion
The METS-IR and TyG indices outperformed HOMA-IR in predicting incident albuminuria.

Association between Combustible Cigarettes and Noncombustible Nicotine or Tobacco Products and Generalized Anxiety Disorder Based on Data from the 8th Korea National Health and Nutrition Examination Survey 2021
Sungkwon Cho, Joo-Hyun Park, Do-Hoon Kim, Hangseok Choi, Youngdoo Park, Hyun-Jin Kim, An-Na Lee, Junghwa Shin, Jaesun Ha
Korean J Fam Med 2024;45(6):317-323.   Published online March 25, 2024
DOI: https://doi.org/10.4082/kjfm.23.0172
Background
Despite the increasing prevalence of anxiety disorders in Korea, there have been no nationwide studies on the association between tobacco status and generalized anxiety disorder (GAD). Furthermore, despite the increasing number of people using noncombustible nicotine or tobacco products (NNTPs), the association between NNTP use and GAD remains unclear. Therefore, this study investigated the association between tobacco use and GAD.
Methods
This nationwide study used data from the 8th Korea National Health and Nutrition Examination Survey (2021) and included 5,454 adults aged ≥19 years who self-reported on the tobacco use and mental health sections. Multivariable logistic regression analysis was performed to investigate the odds ratios (ORs) of GAD (Generalized Anxiety Disorder-7 score ≥10) according to tobacco status among Korean adults. The severity of anxiety was assessed using the Generalized Anxiety Disorder-7 scale.
Results
Compared to never tobacco users, the ORs of GAD for combustible cigarette smokers and NNTP users were 2.74 (95% confidence interval [CI], 1.66–4.50) and 2.11 (95% CI, 1.16–3.83), respectively. The OR of GAD for former tobacco users was 1.63 (95% CI, 0.98–2.72).
Conclusion
Tobacco use (combustible cigarettes and NNTP) was positively associated with GAD. However, in former tobacco users, there was no significant association with GAD when compared with never tobacco users. Given the OR of GAD among tobacco users, it is crucial to pay attention to screening for GAD and implement appropriate early interventions.

Background
This study aimed to examine the effects of different types of skipped meals on cardiometabolic risk factors (CMRF) in Korean adults.
Methods
We analyzed 14,062 adults from the Korea National Health and Nutrition Examination Survey conducted between 2016 and 2018. The irregularity of breakfast, lunch, and dinner consumption was assessed using 24-hour recall data, and we categorized the habit of skipping regular meals into eight types. Multiple linear regression was used to estimate the association between each type of meal skipping and the CMRF. We also presented the estimated effects of individual types of meal skipping on the CMRF based on their predicted values and mean differences.
Results
Korean adults tended to have irregular meal consumption habits when they had one or more of the following characteristics: female sex, under the age of 50 years, middle-high to high household income, high school or college or higher education levels, alcohol consumption, and current smoking. Compared to regular eaters, we have observed significantly higher total cholesterol in the following types of meal skipping: irregular breakfast (IB) (P<0.001), irregular lunch (P=0.005), irregular breakfast and lunch (IBL) (P=0.001), irregular breakfast and dinner (P=0.001); higher low-density lipoprotein-cholesterol in IB (P=0.009); higher triglyceride in IB (P=0.005) and IBL (P=0.034); and higher fasting glucose in IB (P=0.046).
Conclusion
Different types of meal skipping were associated with CMRF. Regular breakfast and lunch consumption should be emphasized to prevent and manage cardiometabolic disorders. However, skipping dinner showed no significant association with CMRF.

Effects of the COVID-19 Pandemic on the Medical Use of Elderly Patients with Hypertension: A Nationwide Cohort Study in Korea
Eunbyul Cho, Sujeong Han, Jae-ryun Lee, Hyejin Lee, Bumjo Oh
Korean J Fam Med 2024;45(5):283-289.   Published online March 4, 2024
DOI: https://doi.org/10.4082/kjfm.23.0129
Background
The coronavirus disease 2019 (COVID-19) pandemic has disrupted healthcare services, including chronic disease management, for vulnerable groups, such as older individuals with hypertension. This study aimed to evaluate hypertension management in South Korea’s elderly population during the pandemic using treatment consistency indices such as the continuity of care (COC), modified, modified continuity index (MMCI), and most frequent provider continuity (MFPC).
Methods
This study used the Korea Disease Control and Prevention Agency-COVID-19-National Health Insurance Service cohort (K-COV-N cohort) from the National Health Insurance Service between 2017 and 2021. The research included a total of 4,097,299 hypertensive patients aged 65 years or older. We defined 2018 and 2019 as the baseline period before the COVID-19 pandemic and 2020 and 2021 as the COVID-19 period and calculated the indices of medical continuity (number of visits, COC, MMCI, and MFPC) on a yearly basis.
Results
The number of visits decreased during the COVID-19 period compared to the baseline period (59.64±52.75 vs. 50.49±50.33, P<0.001). However, COC, MMCI, and MFPC were not decreased in the baseline period compared to the COVID-19 period (0.71±0.21 vs. 0.71±0.22, P<0.001; 0.97±0.05 vs. 0.96±0.05, P<0.001; 0.8±0.17 vs. 0.8±0.17, P<0.001, respectively).
Conclusion
COVID-19 had no significant impact on the continuity of care but affected the frequency of outpatient visits for older patients with hypertension. However, this study highlights the importance of addressing healthcare inequalities, especially in older patients with hypertension, during pandemics and advocates for policy changes to ensure continued care for vulnerable populations.

Barriers, Facilitators of Iron and Folic Acid Supplementation, and Deworming Program among School-Going Adolescents of Deoghar, Jharkhand, India: A Mixed-Methods Study
Bijit Biswas, Anuradha Gautam, G. Jahnavi, Richa, Pratima Gupta, Saurabh Varshney
Korean J Fam Med 2024;45(5):274-282.   Published online February 28, 2024
DOI: https://doi.org/10.4082/kjfm.23.0100
Background
This study aimed to identify barriers and facilitators of iron and folic acid supplementation and deworming programs among school-going adolescents.
Methods
A mixed-method observational study was conducted among adolescents in the 8th to 10th standards and their teachers across four schools in Deoghar, Jharkhand, India, using simple random sampling. The study included a questionnaire on socio-demographics, knowledge (34 items) (α=0.894), attitudes (2 items) (α=0.711) toward iron deficiency anemia, awareness of the Weekly Iron and Folic Acid Supplementation (WIFS) program and deworming (20 items) (α=0.783), and practices related to iron folic acid supplementation (IFS) and deworming, along with qualitative components. Data were analyzed using jamovi.
Results
Compliance rates for IFS and deworming were 27.5% and 67.9%, respectively. The multivariable logistic regression analysis showed that sex, religion, caste, father’s educational status, per capita monthly family income (PCMI), diet type, adequate knowledge, and positive attitude toward anemia influenced IFS compliance. Religion, PCMI, and prior information on the importance of deworming facilitate compliance. Implementation barriers included irregular medication supply and a lack of student awareness.
Conclusion
Periodic evaluation, regular sensitization, and a consistent drug supply are necessary to effectively implement WIFS and deworming programs in the study area.

Background
Osteoporosis is one of the inevitable diseases affecting an aging society, substantially impacting the quality of life of its population. Protein intake has been shown to be beneficial in reducing the incidence of osteoporosis, and the effects of both animal and vegetable proteins have been studied. However, the relationship between processed meat consumption and osteoporosis has not been studied in Korea. Therefore, we aimed to analyze the correlation between processed meat consumption and incident osteoporosis in adults.
Methods
Our analysis included 1,260 adults aged 50 years and older from the Korean Genome and Epidemiology Study (KoGES), recruited between 2005 and 2020. Participants were categorized into two groups according to their processed meat intake, assessed using a semi-quantitative 103-food item food frequency questionnaire. Diagnosis of osteoporosis was based on questionnaire answers. Multiple Cox hazard regression analyses were conducted to examine the association between processed meat intake and incident osteoporosis.
Results
During an average follow-up period of 8.8 years, 230 participants developed osteoporosis. According to the Cox proportional regression models, the hazard ratio (95% confidence interval) of incident osteoporosis in the high intake group was 0.62 (0.41–0.94), compared to the low intake group after adjusting for confounding variables.
Conclusion
These findings reveal that processed meat protein intake is inversely related to the incidence of osteoporosis in adults aged 50 years and older. This in turn suggests that processed meat intake can be proposed as an additional strategy to prevent osteoporosis.

Background
Noncombustible nicotine or tobacco product (NNTP) use, and cigarette smoking are associated with a high likelihood of unhealthy weight control behaviors (UWCBs) among adolescents. However, no study has addressed the differences in UWCBs among non-users, single users of combustible cigarettes (CCs) or NNTPs and dual users. This study compared the frequencies of weight control behaviors according to the status of CC and NNTP use among Korean adolescents.
Methods
This was a cross-sectional study of 25,094 adolescents who had attempted to reduce or maintain their body weight during the past 30 days, using data from the 15th Korea Youth Risk Behavior Survey, 2019. Data on the status of CC and NNTP use, weight status, and weight control behaviors were obtained using self-report questionnaires. Subjects were categorized into four groups: non-users, cigarette-only users, NNTP-only users, and dual users.
Results
Among boys and girls, current smokers and NNTP users were 8.9%±0.3% and 5.5%±0.3%, and 4.2%±0.2% and 1.7%±0.1%, respectively. Among boys, NNTP-only users were more likely to engage in extreme weight control behaviors than non-users. Among girls, users of either CCs or NNTPs were more likely to engage in extreme weight control behaviors and less extreme weight control behaviors than non-users.
Conclusion
This study shows that users of either CCs or NNTPs are more likely to engage in UWCBs, and NNTP-only users are the most likely to do so.

Relationship between Serum Total Testosterone Concentration and Metabolic Syndrome in Premenopausal Obese Women
Kyu-Jin Kim, Jun-Ho Lee, Seong-Ju Kim, Byung-Yeon Yu, Jee-Hyun Kang
Korean J Fam Med 2024;45(4):215-222.   Published online February 28, 2024
DOI: https://doi.org/10.4082/kjfm.23.0089
Background
Men with low testosterone levels are at an increased risk of developing metabolic syndrome, irrespective of age or obesity. However, the relationship between metabolic syndrome and testosterone levels in women remains unclear. We compared the total testosterone concentrations between premenopausal obese women with and without metabolic syndrome and identified the factors affecting these concentrations.
Methods
A single-center retrospective analysis was conducted using the medical records of 580 premenopausal women with obesity. The diagnostic criteria for metabolic syndrome were established using the National Cholesterol Education Program Adult Treatment Panel III guidelines.
Results
The mean±standard deviation age, weight, and body mass index were 38.8±8.4 years, 78.0±11.8 kg, and 30.0±4.1 kg/m2, respectively. The mean total testosterone concentration was lower in the metabolic syndrome group than in the non-metabolic syndrome group (n=385 vs. n=195; 0.22±0.10 ng/mL vs. 0.24±0.11 ng/mL; P<0.001). In a model adjusted for age, body mass index, skeletal muscle mass, body fat mass, and body fat percentage, the odds ratio for metabolic syndrome with respect to the total testosterone level was 0.128 (P=0.028). Testosterone concentration was negatively correlated with age (r=-0.334), systolic blood pressure (r=-0.084), and triglyceride concentration (r=-0.093) but positively correlated with weight (r=0.144), body mass index (r=0.140), waist circumference (r=0.133), body fat mass (r=0.167), and body fat percentage (r=0.167). Stepwise regression analysis revealed that age (β=-0.004, P<0.001), body mass index (β=0.003, P=0.004), and high-density lipoprotein cholesterol concentration (β=0.001, P=0.019) were independently associated with total testosterone concentration (adjusted R2=12.6%).
Conclusion
Metabolic syndrome and obesity may be independently associated with testosterone levels in premenopausal women with obesity.

Factors Associated with Depression among Working-Age Household Heads in Korea: A Cross-Sectional Household Study
Thi Thanh Lan Nguyen, Van Cuong Nguyen
Korean J Fam Med 2024;45(4):207-214.   Published online February 14, 2024
DOI: https://doi.org/10.4082/kjfm.23.0081
Background
Depression is a mental disorder common worldwide. This study determined the relationships between demographics, health status, household parameters, and depression rates among working-age household heads.
Methods
We analyzed data from the Korea Welfare Panel Study Survey conducted in 2020. The 11-item version of the Center for Epidemiologic Studies Depression Scale was used to assess depression. Bivariate analyses and a multiple logistic regression model were used to evaluate the influence of these factors on depression among household heads.
Results
The overall prevalence of depression among working-age household heads was 11.69% (19.83% of females and 9.58% of males). The relative risk of depression was 1.71 times higher among the unemployed than among wage earners and 2.18 times higher among those with low income than among those with general income. The relative risk of depression was 3.23 times higher in those with poor health status than in those with good health, and 2.45 times more in those with severe disabilities than in those without disabilities. The rate of depression decreased with education level, number of family members, and presence of children but increased with the presence of the disabled or elderly.
Conclusion
This study provides a comprehensive overview of depression among working-age household heads and identifies factors strongly associated with depression. These findings may have implications for policymakers to reduce the burden on and improve the quality of life of household heads.

Association between Chronic Atrophic Gastritis and Bone Mineral Density among Women Older than 40 Years of Age in Korea
Seulki Lee, Jae Moon Yun, Jin-Ho Park, Hyuktae Kwon
Korean J Fam Med 2024;45(4):199-206.   Published online February 15, 2024
DOI: https://doi.org/10.4082/kjfm.22.0139
Background
Chronic atrophic gastritis causes hypochlorhydria, hypergastrinemia, and malabsorption of nutrients, leading to lower bone mineral density. The few studies that investigated the association between chronic atrophic gastritis and bone mineral density have reported inconsistent findings. As such, the present study assessed the association between chronic atrophic gastritis and bone mineral density among a large sample of women >40 years of age in Korea.
Methods
Data from 8,748 women >40 years of age who underwent esophagogastroduodenoscopy and bone densitometry were analyzed. Chronic atrophic gastritis was diagnosed using esophagogastroduodenoscopy. Bone mineral density of the lumbar vertebrae (L), femur neck, and femur total, measured using dual-energy X-ray absorptiometry, were the primary outcome variables. Low bone mineral density, which could be diagnosed as osteoporosis or osteopenia, was defined and analyzed as a secondary outcome. Linear regression was used to calculate adjusted mean values of bone mineral density. The association between low bone mineral density and chronic atrophic gastritis was analyzed using multiple logistic regression.
Results
The adjusted mean bone mineral density for L1–L4 was 1.063±0.003, femur neck (0.826±0.002), and femur total (0.890±0.002) were significantly lower in patients with chronic atrophic gastritis than others (1.073±0.002, 0.836±0.001, 0.898±0.002, respectively; all P<0.01). Women with chronic atrophic gastritis exhibited an increased likelihood for osteopenia or osteoporosis, even after adjusting for age and other confounding factors (odds ratio, 1.25; 95% confidence interval, 1.13–1.40; P<0.01). However, subgroup analysis revealed statistical significance only in postmenopausal women (odds ratio, 1.27; P<0.001).
Conclusion
Chronic atrophic gastritis was associated with lower bone mineral density and a higher risk for osteopenia or osteoporosis among postmenopausal women.
