Metformin is the most widely used antihyperglycemic drug in patients with type 2 diabetes (T2D). Over the past 2 decades, several studies have highlighted a substantial increase in the risk of vitamin B12 deficiency in patients with T2D on metformin therapy. This can lead to several complications and induce or exacerbate peripheral neuropathy. Despite these data, there are no definite guidelines for screening, diagnosing, and treating vitamin B12 deficiency in patients with T2D on metformin therapy. Therefore, in this narrative review, we aimed to suggest a practical diagnostic and therapeutic strategy to address vitamin B12 deficiency in patients with T2D receiving metformin treatment. Clinical evidence supporting an increased risk of vitamin B12 deficiency in patients with T2D on metformin therapy and its risk factors and potential complications are also discussed.

The coronavirus disease 2019 (COVID-19) pandemic is notable among infectious diseases for its distinctive impact, which has halted millions of livelihoods owing to strict social distancing rules and lockdowns. Consequently, millions of individuals have turned to online sources, particularly social media, to remain informed about the virus. The transition to digital sources has resulted in an abundance of information, including both accurate and misleading or false content being shared and consumed on online platforms, contributing to what is commonly referred to as an “infodemic.” Although these platforms have been valuable tools for healthcare professionals and public health authorities in disseminating crucial public health messages, they have also aided in the spread of misleading and false information. The widespread dissemination of false information has been instrumental in propagating harmful beliefs and behaviors such as vaccine hesitancy, promoting discriminatory attitudes, and endorsing false beliefs about the efficacy of certain therapeutic products for treating COVID-19. False information has undoubtedly become a challenge and burden for governments, health professionals, and the general population. This review has three main objectives: (1) to assess the scope of the “infodemic” issue, including investigating the factors contributing to the spread of false information online; (2) to examine the multifaceted consequences resulting from false information; and (3) to argue that an interdisciplinary, multi-layered approach, encompassing a focus on prevention, deterrence, and education, should be adopted to prevent the conception and dissemination of false information in this modern digital age.

Background
Physical activity (PA) is associated with a favorable metabolic risk profile in adults. However, its role in adolescents remains unclear. In this study, using data (2019–2021) from the 8th Korea National Health and Nutrition Examination Survey, we investigated the optimal exercise type for preventing metabolic complications in adolescents.
Methods
A total of 1,222 eligible adolescent participants (12–18-year-old) were divided into four groups as follows: aerobic exercise (AE), resistance exercise (RE), combined aerobic and resistance exercise (CE), and no exercise (NE). Daily PA was assessed using the international PA questionnaire. Blood samples were collected to measure lipid, glucose, and insulin levels. Additionally, the homeostasis model assessment for insulin resistance (HOMA-IR) and triglyceride-glucose (TyG) indices were measured. Multivariate regression analysis was used to compare the metabolic risk factors across the PA groups before and after propensity score matching (PSM) adjustment for confounding variables.
Results
The CE group exhibited improved fasting glucose levels, lower TyG index, reduced white blood cell count, and higher high-density lipoprotein (HDL) cholesterol levels than the NE group. The RE group exhibited lower mean blood pressure, triglyceride, fasting insulin, HOMA-IR, TyG index and a reduced risk of metabolic syndrome than the NE group. The AE group had higher total and HDL cholesterol levels. In detailed comparison of the AE and RE groups, the RE group consistently exhibited favorable metabolic parameters, including lower blood pressure and total and low-density cholesterol levels, which persisted after PSM.
Conclusion
These findings highlight the positive effects of PA on cardiovascular risk factors in adolescents. Thus, RE may have a more favorable metabolic effect than AE. Further studies are needed to validate the benefits of exercise according to the exercise type.

Background
Evidence on the association between obesity parameters, including body mass index (BMI) and waist circumference (WC), and osteoarthritis is limited. This study aimed to investigate these associations in Korean adults.
Methods
This nationwide cross-sectional study used data from 24,101 adults aged ≥19 years who participated in the Korea National Health and Nutrition Examination Survey 2016–2020. Odds ratios (ORs) and 95% confidence intervals (CIs) for osteoarthritis according to BMI and WC were analyzed using multivariable logistic regression analyses.
Results
The prevalence of osteoarthritis was higher in individuals with general (10.0%) and abdominal obesity (12.8%) compared with those without. Greater BMI and WC were associated with a higher prevalence (P<0.001) and risk of osteoarthritis (Model 3, P for trend <0.001). Individuals with general and abdominal obesity were associated with a 1.50-fold (OR, 1.50; 95% CI, 1.35–1.67) and 1.64-fold (OR, 1.64; 95% CI, 1.47–1.84) increased risk of osteoarthritis, compared with those without. Similar associations were observed in subgroups according to age, sex, smoking status, and presence of diabetes mellitus. The odds of osteoarthritis 1.73-fold increased (OR, 1.73; 95% CI, 1.53–1.95) in individuals with both general and abdominal obesity compared with those without any of them.
Conclusion
Greater BMI, WC, and general and abdominal obesity were associated with an increased risk of osteoarthritis in Korean adults. Appropriate management of abdominal and general obesity may be important to reduce the risk of osteoarthritis.

Background
In patients with breast cancer, a healthy diet can help reduce breast cancer-specific recurrence, mortality, and comorbid chronic disease rates. There have been few studies on dietary habits immediately after breast cancer diagnosis, especially those involving the Asian population. Therefore, this study aimed to compare the nutritional habits of newly diagnosed patients with breast cancer and the general population without cancer in Korea using propensity score (PS) matching.
Methods
We conducted a case-controlled study of 157 patients with breast cancer and 2,363 cancer-free control participants from the Korea National Health and Nutrition Examination Survey. The PS values for the predicted probability of patients with breast cancer and the general population were estimated using logistic regression analysis, including age and body mass index. The dietary patterns were assessed using a 24-hour recall of 1 day and the Food Frequency Questionnaire.
Results
PS matching showed that patients with breast cancer consumed fewer calories and carbohydrates; however, they consumed more protein and fat compared to the general population. Compared to the general population, patients with breast cancer consumed more healthy foods such as fish, seaweed, vegetables, fruit, mixed-grain rice, and nuts; however, they also consumed more soup, stew, and red meat.
Conclusion
Newly diagnosed patients with breast cancer have some healthy dietary habits compared to the general population. However, there is considerable room for improvement in their diet quality. Our results support the need to develop tailored dietary recommendations for patients with breast cancer during the diagnostic and posttreatment periods to improve their diet quality.

Background
Predicting the risk of osteoporotic fractures is vital for prevention. Traditional methods such as the Fracture Risk Assessment Tool (FRAX) model use clinical factors. This study examined the predictive power of the FRAX score and machine-learning algorithms trained on FRAX parameters.
Methods
We analyzed the data of 2,147 female participants from the Ansan cohort study. The FRAX parameters employed in this study included age, sex (female), height and weight, current smoking status, excessive alcohol consumption (>3 units/d of alcohol), and diagnosis of rheumatoid arthritis. Osteoporotic fracture was defined as one or more fractures of the hip, spine, or wrist during a 10-year observation period. Machine-learning algorithms, such as gradient boosting, random forest, decision tree, and logistic regression, were employed to predict osteoporotic fractures with a 70:30 training-to-test set ratio. We evaluated the area under the receiver operating characteristic curve (AUROC) scores to assess and compare the performance of these algorithms with the FRAX score.
Results
Of the 2,147 participants, 3.5% experienced osteoporotic fractures. Those with fractures were older, shorter in height, and had a higher prevalence of rheumatoid arthritis, as well as higher FRAX scores. The AUROC for the FRAX was 0.617. The machine-learning algorithms showed AUROC values of 0.662, 0.652, 0.648, and 0.637 for gradient boosting, logistic regression, decision tree, and random forest, respectively.
Conclusion
This study highlighted the immense potential of machine-learning algorithms to improve osteoporotic fracture risk prediction in women when complete FRAX parameter information is unavailable.

Shared decisions, in which physicians and patients share their agendas and make clinical decisions together, are optimal for patient-centered care. Shared decision-making (SDM) training in family medicine residency is always provided, but the best training approach for improving clinical practice is unclear. This review aims to identify the scope of the literature on SDM training in family medicine residency to better understand the opportunities for training in this area. Four databases (Embase, MEDLINE, Scopus, and Web of Science) were searched from their inception to November 2022. The search was limited to English language and text words for the following four components: (1) family medicine, (2) residency, (3) SDM, and (4) training. Of the 522 unique articles, six studies were included for data extraction and synthesis. Four studies referenced three training programs that included SDM and disease- or condition-specific issues. These programs showed positive effects on family medicine residents’ knowledge, skills, and willingness to engage in SDM. Two studies outlined the requirements for SDM training in postgraduate medical education at the national level, and detailed the educational needs of family medicine residents. Purposeful SDM training during family medicine residency improves residents’ knowledge, skills, and willingness to engage in SDM. Future studies should explore the effects of SDM training on clinical practice and patient care.

Medication review is an intervention with the potential to reduce drug-related problems (DRPs) in the elderly. This study aimed to determine the effect of pharmacists’ medication reviews on geriatric patients. This study accessed two online databases, MEDLINE Complete and Scopus, and examined all studies published in English between 2019 and 2023, except for reviews. The studies included (1) participants over 65 years of age and (2) medication reviews conducted by pharmacists. The titles, abstracts, and full texts were reviewed for data extraction to determine whether the studies satisfied the inclusion and exclusion criteria. Forty-four of the initial 709 articles were included in this study. The articles included discussions on the incidence rates of DRPs and potentially inappropriate medications (PIMs) (n=21), hospitalization (n=14), medication adherence (n=9), quality of life (QoL) (n=8), and falls (n=7). Pharmacist medication reviews were associated with a reduced incidence of DRPs and PIMs, and improved adherence to medications. Patients’ overall QoL is also increasing. However, pharmacist medication reviews were not strongly associated with decreased hospitalization or falls. A pharmacist’s medication review may be a feasible intervention for reducing the incidence rates of DRPs and PIMs, regardless of whether it is performed as a sole intervention or supplemented with other interventions. The intervention was also effective in increasing medication adherence and QoL.

We report a rare case of high-volume training-related myopericarditis. A male, 18 years old, elite road bicycle racing cyclist with high-volume training of 1,000 km per week for >7 years, presented with progressively worsening exertional breathlessness, reduced effort tolerance, and one episode of cardiac syncope. The symptoms were present prior to the coronavirus disease 2019 pandemic but made worse with the sudden increase in the volume of training after lockdown periods in preparation for competition. He exhibited multiple premature ventricular ectopic beats during his resting electrocardiogram, with a normal echocardiogram and non-elevated cardiac enzyme. The exercise stress test revealed similar multiple premature ventricular beats, warranting further investigation using cardiac magnetic resonance imaging (MRI). The findings of the cardiac MRI were suggestive of myopericarditis. He was instructed to refrain from training and initially started with a short course of colchicine. However, his symptoms deteriorated, and cardiac MRI revealed a decrease in the left ventricular ejection fraction from 59% to 50%. His treatment was escalated to a short course of tapered dose steroid, anti-failure medication and gradual, supervised, return to sports program. This case report highlights the discussion of return to play in athletes with myopericarditis.

Background
Primary care physicians perform a comprehensive role by providing continuous, patient-centered, and accessible healthcare and establishing connections with specialized care. However, the association between the supply of primary care physicians and mortality rates in South Korea has not been thoroughly investigated.
Methods
This study utilized data from 229 si-gun-gu in South Korea from 2016 to 2020. The densities of primary care physicians, physicians in functional primary clinics, specialists in primary care facilities, and active physicians per 100,000 people were independent variables. Age-adjusted all-cause mortality and cause-specific mortality rates per 100,000 individuals were the dependent variables. Negative binomial regression, negative binomial regression with a pseudo-panel approach, and geographically weighted regression were used to analyze the data.
Results
Our study revealed a significant negative association between the density of primary care physicians and all-cause mortality. An increase in a primary care physician per 100,000 population was significantly linked to a 0.11% reduction in all-cause mortality (incidence rate ratio, 0.9989; 95% confidence interval, 0.9983–0.9995). Similar associations have been observed between mortality rates owing to cardiovascular diseases, respiratory tract diseases, and traffic accidents.
Conclusion
This study provides evidence that having a higher number of primary care physicians in South Korea is associated with lower mortality rates. Future research should consider better indicators that reflect the quality of primary care to better understand its impact on population health outcomes. These findings emphasize the significance of strengthening primary care in the South Korean healthcare system to improve the overall health and wellbeing.

Background
Non-alcoholic fatty liver disease (NAFLD) recently became a leading liver disease that threatens health worldwide. Low muscle strength, obesity, insulin resistance, and metabolic syndrome are recognized key factors for NAFLD. However, the impact of low muscle strength itself in different metabolic conditions has not been widely studied.
Methods
A cross-sectional analysis was performed of a sample of 5,427 participants from the 2019 Korea National Health and Nutrition Examination Survey. Relative handgrip strength (rHGS, defined as handgrip strength/body mass index) was used to assess muscle strength. The cut-off values for a low rHGS were 1.405 for men and 0.850 for women. NAFLD was diagnosed if the Hepatic Steatosis Index was >36. Participants were stratified according to insulin resistance, metabolic syndrome, and central obesity for the subgroup analyses.
Results
Complex sample multivariate logistic regression analysis revealed a significant association between low muscle strength and NAFLD after the adjustment for other confounders (odds ratio [OR], 1.92; P<0.001). In the insulin resistance, metabolic syndrome, and central obesity subgroups, a significant association between low muscle strength and NAFLD remained (OR, 1.66–4.19 depending on subgroup; all P<0.05), whereas it did not in the no central obesity group.
Conclusion
This study demonstrated that low muscle strength is correlated with a risk of NAFLD. This relationship was independent of insulin resistance and metabolic syndrome but was dependent on the presence of central obesity.

Background
Maintaining a usual source of care (USC), which is crucial for primary healthcare, encompasses initial contact, comprehensive services, coordinated care, and ongoing support. However, limited research exists on the relationship between USC and medication adherence in patients with hypertension. This study aimed to investigate the association between USC and medication adherence among patients with hypertension.
Methods
Data from the 2nd Korea Health Panel Survey 2020 were analyzed. The final sample consisted of 3,318 participants aged 19 years or older diagnosed with hypertension. USC was categorized into three groups: no USC, place only (without a regular doctor), and regular doctor. Medication adherence was assessed using detailed items (dose, frequency, time, no stop) and a 4-point Likert scale. A logistic regression analysis was conducted with control for relevant variables.
Results
Compared to the no USC group, the regular doctor group had significantly higher odds ratios (ORs) for overall perfect/high medication adherence rates: 1.70 (95% confidence interval [CI], 1.42–2.03) and 1.59 (95% CI, 1.14–2.20). Similar results were observed for each adherence item, including prefect dose (OR, 2.14; 95% CI, 1.73– 2.63), frequency (OR, 1.87; 95% CI, 1.53–2.28), time (OR, 1.72; 95% CI, 1.43–2.07), and no stop (OR, 1.56; 95% CI, 1.09–2.23)/high frequency (OR, 2.47; 95% CI, 1.21–5.01), time (OR, 2.30; 95% CI, 1.19–4.44). However, the place only group showed no significant differences in medication adherence except for perfect adherence to dose (OR, 1.35; 95% CI, 1.06–1.71).
Conclusion
These findings provide evidence supporting the need for healthcare policies that encourage having a regular doctor in South Korea, which has a healthcare system with limited primary care.

Although major countries, such as South Korea, have developed and disseminated national smoking cessation guidelines, these efforts have been limited to developing individual societies or specialized institution-based recommendations. Therefore, evidence-based clinical guidelines are essential for developing smoking cessation interventions and promoting effective smoking cessation treatments. This guideline targets frontline clinical practitioners involved in a smoking cessation treatment support program implemented in 2015 with the support of the National Health Insurance Service. The Guideline Development Group of 10 multidisciplinary smoking cessation experts employed the Grading of Recommendations Assessment, Development, and Evaluation (GRADE)-ADOLOPMENT approach to review recent domestic and international research and guidelines and to determine evidence levels using the GRADE methodology. The guideline panel formulated six strong recommendations and one conditional recommendation regarding pharmacotherapy choices among general and special populations (mental disorders and chronic obstructive lung disease [COPD]). Strong recommendations favor varenicline rather than a nicotine patch or bupropion, using varenicline even if they are not ready to quit, using extended pharmacotherapy (>12 weeks) rather than standard treatment (8–12 weeks), or using pharmacotherapy for individuals with mental disorders or COPD. The conditional recommendation suggests combining varenicline with a nicotine patch instead of using varenicline alone. Aligned with the Korean Society of Medicine’s clinical guideline development process, this is South Korea’s first domestic smoking cessation treatment guideline that follows standardized guidelines. Primarily focusing on pharmacotherapy, it can serve as a foundation for comprehensive future smoking cessation clinical guidelines, encompassing broader treatment topics beyond medications.

The burgeoning interest in precision medicine has propelled an increase in the use of genome tests for screening purposes within the healthy population. Gene screening tests aim to pre-emptively identify those individuals who may be genetically predisposed to certain diseases. However, as genetic screening becomes more commonplace, it is essential to acknowledge the unique challenges it poses. A prevalent issue in this regard is the occurrence of falsepositive results, which can lead to unnecessary additional tests or treatments, and psychological distress. Additionally, the interpretation of genomic variants is based on current research evidence, and can accordingly change as new research findings emerge, potentially altering the clinical significance of these variants. Conversely, a further prominent concern regards false assurances in genetic testing, as genetic tests can yield false-negative results, potentially posing a significant clinical risk. Moreover, the results obtained for the same disease can vary among different genetic testing services, due to differences in the types of variants assessed, the scope of tests, analytical methods, and the algorithms used for predicting diseases. Consequently, whereas genetic testing holds significant promise for the future of medicine, it poses unique challenges. If conducted without a full understanding of its implications, genetic testing may fail to achieve its purpose potentially hindering effective health management. Therefore, to ensure a comprehensive understanding of the implications of genetic testing within the general population, sufficient discussion and careful consideration should be given to counseling based on gene test results.

The simultaneous development of diabetic ketoacidosis (DKA) and thyroid storm (TS) is a rare but potentially lifethreatening condition that requires immediate and targeted treatment. However, their combined diagnosis poses a serious challenge because of the similarities between their clinical manifestations. To date, only a few dozen cases have been described; most of which have been linked to the progression of thyrotoxicosis or uncontrolled hyperglycemia as contributing factors. We present the case of a 37-year-old woman with type 1 diabetes mellitus and Graves’ disease who presented with both TS and DKA. She was initially admitted to the emergency department as a suspected case of stroke. Severe hypoglycemia significantly lowered her alertness to TS and probably provoked a sharp hyperthyroid decompensation, thereby leading to subsequent DKA development.

Background
To determine the association between type 2 diabetes mellitus and the consumption of various fruits.
Methods
The Korean Genome And Epidemiology Study is an ongoing prospective longitudinal cohort study of community dwellers and participants (men and women, aged 40–69 years) recruited from the national health examinee registry of Korea. Their individual consumption habits for 12 different fruit types were recorded using food frequency questionnaires. The fruits were then divided into three groups according to their glycemic indexes and glycemic loads. Participants with extreme caloric intakes, pre-existing type 2 diabetes mellitus, chronic kidney diseases, chronic liver diseases, and ongoing cancer treatments were excluded. The incidence of type 2 diabetes in the cohort was identified through self-reporting and supplemented by glycated hemoglobin and fasting blood glucose levels.
Results
A total of 2,549 cases of type 2 diabetes were documented during 283,033.8 person-years of follow-up. After adjusting for personal, lifestyle, and dietary risk factors for diabetes, the pooled hazard ratio of type 2 diabetes for every serving per week of total whole fruit consumption was 1.02 (95% confidence interval [CI], 0.99–1.06; P=0.2). With mutual adjustment of individual fruits, the pooled hazard ratios of type 2 diabetes for every serving per week were 0.94 (95% CI, 0.88–1.00; P=0.039) for bananas, and 0.90 (95% CI, 0.84–0.96; P<0.001) for grapes.
Conclusion
Our findings suggest associations between the consumption of certain fruits and the risk of developing type 2 diabetes. A greater consumption of grapes was significantly associated with a lower risk of type 2 diabetes in our cohort, but the total amount of fruit consumption was not associated with a reduced risk.

Background
Appropriate nutrition is necessary for maintaining good health in the general population. During primary physician training, it is important to educate residents on the basic concepts of nutrition and methods to manage nutritional aspects according to various disease. However, little is known about the perception of nutritional education among Korean family medicine residents. This study analyzed the recognition of the importance of nutritional education, the amount received, and satisfaction with it as well as self-perceived competency in various nutrition topics among residents.
Methods
Web-based questionnaires were sent via mobile messages to all the residents registered with the Korean Academy of Family Medicine (KAFM). Out of 566 residents, 68 voluntarily participated in the study. The questionnaire consisted of 41 items related to perceptions of nutrition education, self-perceived competency in nutrition topics, and demographic characteristics.
Results
The response rate was 12.01%. Residents rated their satisfaction with nutrition education at 4.78 out of 10, and 83.3% considered it important. However, only 13.24% of the participants felt that it was adequate. The most common training method for nutrition education was lectures at KAFM conferences. Among the 29 nutritional topics, the residents reported highest confidence in subjects related to chronic diseases such as obesity (77.94%), diabetes (75%), cardiovascular disease (67.65%), gastrointestinal disorders (67.65%), and weight loss management (67.65%). Conversely, topics related to women (36.76%), children and adolescents (38.23%), drug-nutrient interactions (39.7%), eating disorders (42.64%), and food labels (42.64%) showed low self-perceived confidence rates.
Conclusion
Korean family medicine residents value nutrition education but believe that more education is necessary and they demonstrate differences in self-perceived competency in various nutrition topics.

Background
Malaysia is the first country in the Western Pacific Region to receive the validation certificate for the elimination of mother-to-child transmission of human immunodeficiency virus (HIV). The validation report recommends making sexual and reproductive health and rights of women living with HIV a priority. This article explores and assesses the sexual and reproductive health, rights, and access to healthcare services of Malaysia’s women living with HIV (WLHIV).
Methods
A qualitative secondary analysis conducted on 73 WLHIV from all over Malaysia comprised 11 in-depth interviews and 16 focus group discussions. Data were extracted from the original interview transcripts that emerged from the following questions: (1) “What are your experiences as a woman living with HIV in relation to your sexual and reproductive health and rights?” (2) “What are your experiences in accessing contraception?” (3) “What are your day-to-day experiences as a woman living with HIV?” Data were analyzed using thematic analysis.
Results
Four themes emerged from the study findings: “lack of negotiation,” “idealism in pregnancy,” “coping with restrictions,” and “past and future fears.” The four themes are grounded in religion, a patriarchal culture, meaning and expectations of motherhood, taking risks and going against medical advice to pursue fertility desires, fear of HIV transmission, and the side effects of contraceptive use.
Conclusion
The complexities involved in decision-making regarding contraceptive use revealed how WLHIV may have unresolved reproductive health needs inconsistent with healthcare providers’ focus on HIV management and prevention. Suggestions are made for improving the sexual and reproductive health and rights of WLHIV in Malaysia, which include establishing a reproductive health counseling program.

Background
Alternative and complementary medicines are widely used to treat migraine headaches. This review aimed to determine the effectiveness of essential oils as an alternative treatment approach.
Methods
A structured search was conducted to identify randomized trials comparing essential oils with a placebo for migraine headaches, using databases (MEDLINE and CENTRAL) to search for articles published between 1966 and 2021. We included trials involving adult males and females diagnosed with migraine headaches according to the International Headache Society. The outcomes included number of attacks, headache severity, associated symptoms, number of days of limited activity, headache duration, use of analgesics, and adverse effects. Seven trials were included with a total of 558 participants.
Results
No difference was observed in the number of migraine headache attacks compared to placebo (mean difference [MD], -1.34; 95% confidence interval [CI], -3.31 to 0.64; I2=94%; P=0.190; four trials, 242 participants; moderate- quality evidence). There was no difference in this outcome between the essential oils treated group and the placebo (MD, -0.38; 95% CI, -1.76 to 0.99; I2 statistics=86%; P=0.580; five trials, 240 participants; moderate-quality evidence).
Conclusion
We found no significant difference between the use of essential oils and placebo in managing migraine headaches.

Manifestations of gender-based violence although many, and sometimes more pronounced in areas of armed conflict, go unnoticed due to multiple factors. Gender-based violence targeted towards women, affect their overall health negatively, particularly the reproductive well-being. Major conflicts arising in the Middle East over the past 10–15 years, ranging from the Arab uprising to the Syrian civil war, have drawn attention world-wide. This study aims to shed light on the importance of recognizing violence against women, its effect on their reproductive health, and the policies that should be implemented to limit its adverse impact. Towards this end, we have highlighted the important role played by all healthcare professionals, epidemiologists, and surveyors working in peace and war areas to recognize such atrocities towards women.

The coronavirus disease (COVID-19) pandemic has led to an alarming increase in domestic violence against women owing to lockdown measures and limited access to support services. This article provides insights into the global prevalence of domestic violence, barriers to seeking help, its impact on women and children, and the best practices implemented worldwide. Domestic violence encompasses various forms of abuse; many young women experience partner violence. Barriers to seeking help include fear, financial constraints, lack of awareness of available services, and distrust among stakeholders. The consequences of domestic violence affect the mental health of both mothers and children. Countries have increased shelter funding and developed innovative protocols to reach survivors and address this issue. However, the healthcare sector’s involvement in addressing domestic violence has been limited. This review advocates collaboration among healthcare institutions and government bodies. Key recommendations include utilizing telehealth services, implementing comprehensive training programs, establishing effective referral systems, enhancing health education, developing a domestic violence registry, improving the responses of law enforcement and justice systems through healthcare integration, promoting data sharing, and conducting further research. Healthcare systems should recognize domestic violence as a public health concern and detect, prevent, and intervene in cases to support survivors.
