Background Fatigue is a common problem in male workers as they have responsibilities in both role in home and in work place. The use of functional food has been one of the popular choices for fatigue recovery. This study was conducted to investigate the prevalence of functional food usage and its relationship with fatigue in male workers.Methods: The study subjects were male workers seen for health check up at a university hospital in Busan from May to July 2009. They completed a questionnaire including social factor, occupational factor, life style, functional food usage and disease status. The subjects were divided into groups according to fatigue severity.Results: Among 770 subjects, 267 (34.7%) consumed functional food daily. Most of them used functional food to recover fatigue as a supplement nutrition by their wife's or surrounding person's recommendation. There were significant difference between fatigue and non-fatigue group in age, occupation satisfaction, alcohol drinking, and insomnia. The prevalence of fatigue was 37.8%. The functional food usage significantly increased with fatigue severity scale (P < 0.001).Conclusion: Fatigue is common problem in male workers. The functional food usage is relation with fatigue severity.

Functional foods are becoming increasingly available to consumers worldwide. The health effects of use of functional foods on cardiovascular diseases must be advised. Omega-3 fatty acid can play a role in primary prevention of deaths from coronary heart disease. It has also been reported to be promising treatment for prevention of deaths from cardiovascular diseases particularly in high-risk group. Vitamin E has no primary prevention of cardiovascular disease, but has high possibility of increasing the risk of heart failure and deaths from cardiovascular disease in high-risk group. Vitamin B complex reduces homocysteine, but don't reduce the risk of cardiovascular disease. Apart from them, gamma linolenic acid, chitosan, soy protein, and red yeast rice may reduce cholesterol levels and the risk of cardiovascular disease, still, further studies are needed. To prevent cardiovascular diseases, it is the most important to main healthy lifestyle habits. Functional foods should only be supplementary.

Background Dietary supplements affect the health and disease status of Koreans. We assessed the patterns of dietary supplements use and the related factors in Korean adults from the 2005 Korea National Health and Nutrition Survey (KNHANES). Methods: Among the subjects, 2,024 men and 2,811 women underwent all the three parts of 2005 KNHANES, which consisted the health survey, the health examination, and the nutritional survey. Reported supplements were classifi ed according to the 2008 Korea Food and Drug Administration Notification. We assessed the relationship between supplements use and socioeconomic state, health behaviors, and chronic diseases. Results: Twenty-nine percent of Korean adults was taking dietary supplements. Vitamin/mineral supplements were the most commonly taken one. Glucosamine/mucopolysaccharide, ginseng, spirulina/chlorella, omega-3, and aloe followed in listing. Supplement users were likely to be woman and middle-aged. Supplement use was associated with older, high income, with spouse, higher education, urban-living, regular exercise, non-smoker, and lower BMI. Musculoskeletal diseases were associated with supplement use. Conclusion: Dietary supplement use is prevalent in Korean adults. The supplement use was associated with some demographics characteristics, health behavior, and chronic diseases. These factors should be considered when evaluating the effi cacy of dietary supplements.

Background Frailty is a wasting syndrome that presents loss of physiological function by aging, lowering of reserve capacity, and disability of body system. It is currently being considered an important issue in geriatrics. This study examined frailty level of Korean elderly in community and whether frailty can be meaningful a predictive factor for functional disability. Methods: Demographic characteristics, the number of chronic diseases and medications, cardiovascular health study (CHS) frailty index, study of osteoporotic fractures (SOF) frailty index, activities of daily living, Instrumental activities of daily living, depression, mini-mental state examination (MMSE) and fall history were examined for 302 men and women over 65 years old who visited the three community seniors welfare centers from February 2008 to June 2008. Results: There were defi nite differences of frailty status by age, educational level, marital status, monthly income, body mass index, the number of chronic diseases, the number of medications, depression, MMSE and fall history (P < 0.05), except in gender (P < 0.432). In logistic regression analysis for functional disability with frailty status defi ned by SOF frailty index, odds ratio to dependency of instrumental activities of daily living (IADL) from the healthy to the prefrail stage increased 6.84 times while from the healthy to the frail stage increased 130.87 times. These effects still increased after covariate adjustment. Also, the CHS frailty index showed the same result although there was some difference in odds ratio.Conclusion: There were meaningful correlations of frailty with functional disability when dividing Korean elderly's frailty levels into the healthy, the prefrail and the frail stages.

Background : Gastrointestinal (GI) symptoms are believed to be common in the general population, and constipation is one of the most representative GI symptoms. However, the prevalence and risk factors of functional constipation are not well known in Korea. We aimed to study the prevalence of, and risk factors for, constipation in the elderly.
Methods : We randomly selected 852 among 854 (excluded by cancer and dementia) subjects, ages 65 yr and older, in three different geriatric welfare facilities in December, 2003. The prevalence of functional constipation was based on the Rome II criteria and the survey on risk factors for constipation was performed.
Results : Functional constipation had a prevalence of 26.6% and there was no difference between men and women. Exercise, fluid·fruit·vegetable intake, anal diseases and age related risk factors were associated with constipation.
Conclusion : In the elderly, constipation is a common complaint. Further studies are now required for risk factors of constipation.
Background : The functional status of elderly has been measured by many different methods including Karz ADL index, Bathel ADL index and physical self- maintenance scale. Among them, Bathel ADL index has been widely used in many countries because of easiness to scoring and administration. Therefore, we translated the Bathel ADL index and tested the translation validity and psychometric properties (validity and reliability) of Korean version of Bathel ADL index.
Methods : The Bathel ADL index was translated by multidisciplinary committee members. The quality of translation was rated by committee members using three criteria (clarity, use of common language, conceptual equivalence). Reliability was tested by internal consistency (Cronbach's alpha), two weeks test-retest reliability, and intraobserver agreement. Clinical validity and construct validity comparison with brain disability grade were tested for validity testing.
Results : Cronbach's alpha was 0.97. Two weeks test-retest correlations coefficient was 0.95 (P=0.00). Interrator agreements were high in all 10 items (κ=0.82∼1.0). Normal control group had lower scores than the patient group (P=0.000). Correlation coefficients between the Korean version of Bathel ADL index score and brain- disability grade was -0.58 (P=0.000).
Conclusion : The Korean version of Bathel ADL index is a valid and reliable instrument for measuring functional status of the elderly.
Background : Dyspepsia is a common symptom and bacause functional dyspepsia is a heterogeneous disorder its pathophysiology is not well established. We need to conceptualize in a so called "biopsychosocial model". Many Koreans tend to consider the importance of dietary habits in causes and treatment of diseases and actually many physicians recommend dietary modification for patients of functional dyspepsia. Therefore, the aim of the present study was to determine if dietary habits was associated with functional dyspepsia.
Methods : Functional dyspepsia was defined and classified by Rome II criteria. This study was performed by case and control method at the outpatient department of family medicine of six university hospitals in Seoul. Self-administered questionnaire for the demographic characteristics and dietary habits were performed in 472 functional dyspeptic patients and 236 normal controls.
Results : Only the economic status among the demographic factors was associated with functional dyspepsia and on the dietary factors. The functional dyspeptic patients reported less than 2 days regular eating for one week (OR=2.01, P=0.019, 95% CI: 1.12∼3.60) and more than 3 days overeating for one week (OR= 2.01, P=0.020, 95% CI: 1.12∼3.63), but no significant difference was found in the daily eating frequency, meal duration, frequency of spicy food comsumption, and breakfast.
Conclusion : Functional dyspepsia was associated with irregular eating patterns and overeating behavior for one week. To prevent functional dyspepsia behavioral modification such as eating regularly and avoiding overeating should be advised.
Background : According as people have an increased interest in early detection of disease and health promotion, people who take health examinations are increased. So this study is aimed to survey common problems about health in community and their frequency by way of investigation on diagnosis in health examination data and to evaluate the effects of risk factors on each disease patterns.
Methods : The medical records of the clients who have taken health examinations for the first time from March 1995 to February 2000 at a health examination center of a university hospital in Seoul were reviewed. The category and number of judged diagnosis, sociodemographic factors are compared and analyzed.
Results : The selected medical records accounted to 22,393. The study subjects consist of 11,544(51.6%) male. Mean age is 52.0±105 years(range 16~90). Mean number of judged diagnosis is 4.04±2.13(range 0~9) per one person and female took more diagnosis than male on an average(4.09±2.17 Vs 3.99±20.9). The organic diagnosis(56.4%) is most in total and other diagnosis is 35.7%, functional diagnosis is 7.9%. The common diagnoses are liver disease(7.17%), decreased physical strength(6.68), hyperlipidemia(6.53%), obesity(5.90%), osteoporosis or postmenopausal syndrome(4.72%), need for immunization against viral hepatitis(4.69%), hypertension(4.20%), functional gastrointestinal disease(3.93%). The number of total diagnosis and organic diagnosis is larger in older age, no exercise, female, smoker, no-spouse, lower education(p<0.05). The number of functional diagnosis is larger in female, younger age, non-smoker, lower education(p<0.05). The number of other diagnosis is larger in no exercise, smoker, female, younger age(p<0.05).
Conclusion : According to health examination, total diagnosis and organic diagnosis are influenced by age, exercise, sex, smoking, spouse, education, functional diagnosis is influenced by sex, age, smoking, education and other diagnosis is influenced by exercise, smoking, sex, age.
Background : It is well-known that dyspeptic symptoms in functional dyspepsia are related to psychological factors such as stress mood disorder. But it is still controversial whether H.pylori infection is a important factor for functional dyspepsia. We conducted this study to investigate whether H.pylori infection or stress are related to dyspeptic symptom severity in functional dyspepsia.
Methods : From Mar. 1 1999 to Apr. 30 1999, attendees to a Health Screening Center and a Family Practice Center were eligible study subjects. The subjects were responded to questionnaire including dyspeptic symptom severity items and BEPSI-K(stress scale). And among eligible subjects, one hundred and thirty two diagnosed with functional dyspepsia by gastrofibroscopy were final study subjects. H. pylori infection was confirmed by antral biopsies & smear (Giemsa stain).
Results : In fuctional dyspepsia, high BEPSI-K score group(upper tertile) complained more severe dyspeptic symptom severity than low BEPSI-K score group(lower tertile) after adjusted for other variables(adjusted OR=8.349, 95% C.I.=2.232-31.231). But the dyspeptic symptom severity was not associated with H.pylori infection status (adjusted OR=1.514, 95% C.I=0.567-4.046)
Conclusion : The dyspeptic symptom severity in functional dyspepsia was associated with stress but not with H.pylori infection status.
Background : Dyspepsia is a common problem. Functional dyspepsia accounts for 40% of all causes of dyspepsia. In view of biopsychosocial medicine, family is an important social background that is the basis of health care. Therefore we studied the relationship between functional dyspepsia and family function.
Methods : The 64 functional dyspepsia patients group and 64 normal control group who visited the department of family medicine, Pusan national university hospital from December 1996 to June 1997 were enrolled in this study. All were examined with gastrofiberscopy, abdominal ultrasonography, and liver function test. Functional dyspepsia patients were sub grouped into ulcer-like dyspepsia, dysmotility-like dyspepsia, and nonspecific dyspepsia. Patients not having these symptoms were classified into control group. For evaluation of family function, we used family APGAR.
Results : Among 64 functional dyspepsia patients, 50.0%(N=32) had ulcer-like dyspepsia, 26.6%(N=17) had dysmotility-like dyspepsia, and 23.4%(N=15) had nonspecific dyspepsia. Average family APGAR score was 5.83(±2.2) in the functional dyspepsia group, and 6.80(±2.4) in the control group(t-test, p=0.007). Among the functional dyspepsia group, moderately family functional subgroup was most common (53.1%), but among the control group, highly family functional subgroup was most common(62.5%). Among subgroups of the functional dyspepsia group, average family APGAR score of dysmotility-like dyspepsia subgroup was lowest.
Conclusion : Subgroups of functional dyspepsia were as follows; ulcer-like 50.0%, dysmotility-like 26.6%, and nonspecific dyspepsia 23.4%. The family APGAR score of functional dyspepsia patients group was lower than normal control group.
