The principal objective of this study was to provide basic data regarding health care services for middle-aged men, via an analysis of the relationships among stress level, food habits and well-being-related attitudes with social-demographic characteristics and health-related factors. The main findings of this study were as follows. The average age of the participants was $48.7{\pm}5.2$. With regard to health status, 18.8% of the participants were diagnosed with digestive diseases within the past year. Stress levels were higher in the participants with lower levels of educational attainment. Furthermore, participants who had become divorced or lived separately from their families, participants who did not have their own houses, and participants who reported low marital satisfaction also had high levels of stress. Our food habits scores revealed meaningful differences among the study subjects, and were shown to vary with marital satisfaction, occupation, and residence type. In terms of both the importance and practice level of well-being-associated food habits, the most frequent response in this study was 'Consume home-made food rather than processed or ready-to-eat food' ($4.30{\pm}0.86$, $3.68{\pm}1.04$). In terms of importance level, the factors most relevant to well-being in terms of food habits were education level, marital satisfaction, residence type, self-assessed health status, smoking, drinking, regular exercises and leisure activities. With regard to practice levels, the degree to which subjects engaged in food habits targeted toward well-being differed meaningfully depending on marital status, marital satisfaction, residence type, family type, self-assessed health status, smoking, drinking, nutritional supplement intake, regular exercises and leisure activities. After analyzing the correlation among stress level, food habit score and the attitude towards well-being-related dietary habits (importance and practice level), we observed a meaningful relationship between the four factors at the level of p<0.001. According to the above result, continuous attention to health, including the appropriate control of smoking and drinking, as well as, stress management, via regular exercises and appropriate food habits is expected to exert a positive influence on the prevention of disease, and is also expected to improve quality of life. For all well-being-associated items, the importance level was shown to be higher than the practice level. Thus, in order to foster health-oriented food habits, we recommend that a new plan be designed, targeted toward ease of active practice for middle-aged men.

Purpose: This study was conducted in order to examine premenstrual symptoms (PMS) according to physical activity of high school girls. Method: Data were collected from 323 high school girls using structured questionnaires, Menstrual Distress Questionnaire (MDQ) and International Physical Activity Questionnaire (IPAQ). The data were analyzed using descriptive statistics, t-test, and AVOVA. Results: The mean score of PMS was low (2.200.81). Among the subcategories, negative feeling (2.491.26) was the highest. Physical activity levels were coded as inactive, minimal activity and health enhancing physical activity, among which minimal activity (53.0%) was the highest. Significant differences in PMS were observed according to subjective health condition (F=10.83, p<.001), alcohol intake (t=-1.99, p=.048), caffeine intake (F=3.04, p=.029), dietary habit (F=4.78, p=.009), amount of menstruation (F=4.57, p=.011), discomfort in daily life (F=28.94, p<.001), degree of menstrual pain (F=41.23, p<.001), method of menstrual pain relief (F=4.29, p=.015), and family history (F=11.45, p<.001). Significant difference in PMS was observed according to the physical activity level (F=3.12, p=.046), and health enhancing physical activity (2.540.87) was the highest. Conclusion: These findings suggest that PMS intervention programs would be considered factors related to PMS. Conduct of further studies is recommended for evaluation of the relationship between physical activity and PMS.

Purpose : To identify general characteristics of school personnel with recent fatigue which was the most frequent symptom among subjective symptoms and to explore fatigue-related factors by evaluating physical and perceived health status, life style, and symptoms through data mining techniques. Methods : We collected a data of the 1,147(male 545, female 602) who were elementary, middle, or high school personnel, answered a questionnaire, and received physical examination in Seoul School Health Center from September to November in 2000. And we investigated the differences between fatigue group and non-fatigue group for demographic characteristics, physical health status, perceived health status, symptoms, and laboratory values by frequency, chi-square test, t-test, or simple logistic regression analysis by SAS package 8.1, and then selected significant variables as input variables of a decision tree analysis of CART model by SAS E-miner. Results : In general characteristics, the fatigue consisted of 41.1%(male 35.2%, female 46.4%) among 1,147 school personnel. In classical statistics, factors related with fatigue were female, lower means of systolic and diastolic pressure, young age, personnel in middle school, irregular eating habit, no exercise a week or less than 30minutes exercise a day, perception of unhealthy status, and subjective symptoms including short of breath at exercise. In simple logistic regression to examine the relationship between selected independent variables and fatigue as a dependent variable, the odds ratio of gender (female vs male) was 1.58 times, and young age ( 20s vs 60s) 20.67 times, and middle vs high school personnel 1.86 times. However, we mined combined several characteristics by SAS-E miner. In CART model, if health perception was healthy, and age was >= 37.5 years, the proportion of the fatigue was only 19.3%. but if health perception was not healthy and symptom was severe 'short of breath' during exercise and age was < 53.5 years, and BMI was >= 22.69, the proportion of the fatigue was up to 84.8%. Conclusions : The fatigue consisted of 41.1%(male 35.2%, female 46.4%). In classical statistics, fatigue-related factors among school personnel were young age, female gender, perceived unhealthy status, subjective physical symptoms, poor life-style, and lower blood pressure rather than only physical health status. However, in data mining, if health perception was healthy and age was >= 37.5 years, the proportion of the fatigue was only 19.3%. but if health perception was not healthy and symptom was severe 'short of breath' during exercise and age was < 53.5 years, and BMI was >= 22.69, the proportion of the fatigue was up to 84.8%.

This study was undertaken to evaluate the relation between obesity and dietary life of children aged 4-7 divided into two groups based on height for age, weight for age and weight for height. Controls were selected based on sex and age similar with those of cases. Cases and controls were selected using the combination of weight for height, weight for age and height for age by the World Health Organization standard. Cases were 23 children judged as obese. Controls were 37 judged as normal. Whether their mother had a job or not, showed relative risk 1.35(95% C1 0.32-5.64). In obese group, employmental statue of mother was 17.4% compared with 13.5% in control group. In mother's concern for cooking pattern, the relative risk was 5.64 and 95% CI was 1.70-18.66 in the item of "We consider the color arrangement when we serve foods" which was the highest rate. The item having the lowest relative risk was "We cook the meal by ourselves with spending time" which of the relative risk was 0.52 and 95% CI was 0.16-1.65. The item having a great significance in the dietary habit of subjects were "They beat the tablewear with the chopstick"(RR:1.64, 95% CI:0.22-12.73) and "I talk with food in my mouth"(RR :1.11, 95% CI:0.39-3.15), and the other items didn't show significancy. Number of food eating per day for male was 30.0$\pm$10.93 in obese group where as 23.2$\pm$9.80 in control group. 22.3$\pm$4.56, 21.8$\pm$10.91 were taken obese group and control group respectively in female. In the survey for general habit in life, the item of "We has a time for conversation with our family regularly" was high correlation to obesity and item of "We made our children change clothes and go to toilet themselvesj has slight relation to obesity. From above, we observed normal and obese children had different factors such as mother's attitude for preparing meals, table manners and habit of living. So we should take a continuous interest in children's dietary life in order to correct the wrong dietary habit and to protect from future problems.

Objectives: Sleep quality is directly related to the health, quality of life and working capacity and is affected by age, gender, exercise, life habits. Gender dissimilarities in sleep quality are acknowledged. However, the gender difference in the quality of sleep in shift workers was not well known. Our aim was to study the less known gender differences in the quality of sleep of shift workers. Methods: 1,008 study subjects aged between 21 and 57 years among these, 637(525 male and 112 female workers) were daytime workers and 371(253 males and 118 female workers) were shift workers. Sleep quality was measured by self-report through the Pittsburg Sleep Quality Index(PSQI) and fatigue was measured by using the Chalder Fatigue Scale(CFS). All data was analyzed using SPSS version 19.0 program. The study was approved by the Institutional Review Board of the Occupational Safety and Health Research Institute. Results: Overall, sleep quality was found to be worse in shift workers than in daytime workers and in female than in male. Fatigue in shift female workers was significantly higher than in daytime female workers and shift male workers. In Spearman correlation analysis results, fatigue were significantly associated with gender, drink habit, regular exercise, working hours and sleep quality. With group male workers as the reference, the odds ratio(OR) for having a CFS was 2.115(${\beta}$ value=0.749, p<0.01), and subjective sleep quality, sleep latency, daytime dysfunction and PSQI were 1.541(${\beta}$ value=0.432, p<0.05), 2.297(${\beta}$ value=0.831, p<0.001), 1.798(${\beta}$ value=0.587, p<0.01) and 2.224(${\beta}$ value=0.799, p<0.01), respectively. Conclusions: Shift work played an important role in lowering the quality of sleep, and the effect was more pronounced in female workers than in male workers. Sleep quality was related to fatigue, especially sleep quality, sleep duration, sleep disturbances and daytime dysfunction were significantly related. Therefore, to improve fatigue and sleep quality of shift worker, it is necessary to improve healthy habits such as regular exercise, smoking cessation, and limited drinking. In particular, it is urgent to develop and implement a regular exercise program to reduce fatigue and improve the quality of sleep in workplace.

Objectives: This study was to examine those life style factors which could affect the changes of health status indices such as ADL and IADL of the Elderly living in rural community. Methods: The subjects of the study were 1,295 elderly people of age over 65 years living in Gyungbook Sung-Ju area selected by random sampling for one month at October 1996. After 4 years, the follow-up study in those subjects were performed, ADL, IADL and general characteristics were measured. Those subjects who had shown high functional health status in first investigation were measured as how their health were changed in relation with their general characteristics and life styles in second investigation. Results: The factor analysis were performed in life style questions, and 6 factors composed of 15 questions of all were selected as the indices of life style. For ADL level, logistic regression analysis, age and educational level in men, and age and economic status in women had significant relation with health status change. Among life style factors, diet factor in men and diet factor, social activity factor in women were found to be significantly related. For IADL level, simple analysis showed that age in men and age, education level in women among general characteristics had related with health status change. Among life style factors, diet factor, stress relieving factor were related in women when general characteristics were also controlled diet factor, stress relieving factor were related in women. Conclusions: In order to prevent functional health status altering in the elderly, it is recommended that the intervention which could promote healthy life styles such as good diet habit, active social participation, and pertinent stress relieving should be considered.

The study purpose was to investigate correlations among dietary habits score, life stress score and health-related quality of life (HRQL) score for female college students with functional constipation (FC). The data were collected in 2008 from 265 female college students: 86 with FC and 179 without FC. The diagnosis of FC was based on the Rome II criteria, and life stress and HRQL were assessed using self-administered life stress questionnaire and SF-36, respectively. The correlations among dietary habit score, life stress score, and HRQL score were evaluated. The averages of age, height, weight, body fat percentage and body mass index (BMI) of female college students were 20.8 years, 160.9 cm, 53.7 kg, 27.8%, and $20.7\;kg/m^2$, respectively. The average dietary habit score of "having meals with diverse foods" was significantly lower in the FC group than in the normal group (p < 0.05). The average faculty problem (p < 0.05), grade problem (p < 0.05), economy problem (p < 0.05), value problem (p < 0.05), and total stress (p < 0.01) scores of the FC group were significantly higher than those of the normal group. The average HRQL score was 70.4 in the FC group and 74.3 in the normal group (p < 0.05). There were significantly negative correlations between total stress score and total food habits score (r = -0.221; p < 0.01) and HRQL score (r = -0.539; p < 0.01) in the FC. These results suggest that female students with FC are highly perceptive to stress and have low HRQL. In addition, female students with FC may require nutritional education about eating diversity.

We studied daily micronutrient intake from vitamin-mineral supplements, health-related life style, clinical case of diseases and food frequency of the Korean middle-aged (40-59 yr, n = 404) to compare the characteristics of non-user (n = 270) and user (n = 134) of vitamin-mineral supplements. Rate of supplement use of the middle-aged was 33.2% and there was significant difference in education level (p = 0.0084) and family income (p = 0.0476) of user and nonuser. Smoking habit (p = 0.0844) and drinking frequency (p = 0.0606) tended to be lower in a supplement user than a non-user. The medical history of a case was significantly higher in users (67.9%) than in non-users (44.4%) (p = 0.001), which suggests that medical history is one of the important motivations of supplement use. Supplement users had the medical history of digestive disease (34.1%), anemia (11.0%) and hypertension (9.9%) in order. Vitamin C was the most frequently supplemented nutrient (81.3%) among vitamin-mineral supplement, and the next orders were vitamins E (73.1%), B$_2$(68.7%) and B$_{6}$ (60.4%). Mean intakes of vitamin B$_1$, iron, selenium, vitamin E, and vitamin C from supplement was 4,260%, 4,030%, 1,660% and 1,330% of RDA, respectively. The supplement users tended to consume most food items including milk ＆ milk products (p ＜ 0.01), rice (p ＜ 0.01), grains (p ＜ 0.05) and cookies (p ＜ 0.01) less frequently than non-users. Conclusively, nutrient intake of vitamin B$_1$, iron, selenium, vitamin E, and vitamin C from supplement was excessively high compared to RDA. We suggest that the toxic effect of excessive supplementation should he informed to supplement user and nutritional education should be focused on the optimal supplement dose.e.

This study aimed to examine the health-related lifestyle habits and eating behaviors according to gender, ethnicity, and residence type of university students in Yanbian, China. Self-administered questionnaires were collected from 302 university students. Of the male students, 12.1% and 42.0% were in the underweight and overweight groups, respectively, and of the female subjects, 21.3% and 16.3%, were in those respective groups. More male than female students preferred the overweight body somatotype. In contrast, about 49.4% of female students were hoping to be underweight, and female students had more obvious difficulties with body somatotype perception, whereas their exercise frequency and time spent exercising per day were much less than those of male students. More Chinese than Korean-Chinese subjects exhibited regular eating habits, which included eating at the same time everyday and at the same frequency per day; these habits were, accompanied by generally healthier lifestyle habits regarding regularity of activity and exercise time. Self-boarding students had a significantly higher BMI ($23.7{\pm}5.1kg/m^2$) and were more likely to be overweight (43.5%) as compared to students who lived in a dormitory or with family. Salty taste was preferred by Chinese students more than Korean-Chinese students, and greasy taste was preferred by Korean-Chinese students as compared with Chinese students. This study found that inherent and environmental factors are related with the dietary behaviors of university students in Yanbian, China. Further studies are required to elucidate the structural elements of family life and the sociocultural factors associated with dietary behaviors in Yanbian.
