Purpose: To understand the dietary habits and factors influencing the dietary habits in adults of an urban community. Method: The data were collected via questionnaires that investigated dietary habits, health behaviors, health-related factors, and general characteristics. A total of 302 subjects were selected from those who had visited an urban public center over a 2-week period. The data of 294 subjects were analyzed using descriptive analysis, t-test, ANOVA, and multiple regression, after 8 questionnaire were excluded due to incomplete data. Results: The degree of dietary habits was in the middle range. The most positive dietary habit was 'intake fibers from vegetables, fruits, and cereals', followed by 'not enjoy salty food and salt' and 'eating breakfast everyday'. The significant predictors influencing dietary habits were age, present smoking behavior, perceived health status, and drinking frequency, and these variables accounted for 27.3% of the variance in the dietary habits score. Conclusion: Health care providers should focus on health promotion planning regarding dietary habits and other health-related behaviors in combination and use integrated strategies regarding the factors that influence dietary habits and other health-related behaviors.

Polycyclic aromatic hydrocarbons (PAHs) are well known for strong carcinogen. However, the human exposure analysis of PAHs is quite difficult and unreliable because of hard for estimation of actual expose dose. Then urinary 1-hydroxypyrene (1-OHP) has been a biological marker of exposure to PAHs. The purpose of this study was to investigate total amount from exposure to PAHs soused by indoor occupational exposure, and residence at Seoul metropolitan area and Kyeonggi province in Korea. Thirty-five housewives were included in this study from April 2003 through February 2004. Dietary habit and general characteristics such as age, type of building, existence of passive smoking, period of residence, fuel type for heating and ventilation type were obtained by self administered questionnaire. Urine samples were collected at morning and freeze quickly. Urinary creatinine was measured for converting into 24 hr urine. Concentration of the indoor PAHs was examined by NIOSH method number 5506. Urinary 1-OHP and PAHs were analysed by HPLC. Correlation coefficient between urinary 1-OHP levels and pyrene concentration of indoor air was 0.66 and statistically significant(P<0.01). The difference of urinary 1-OHP level due to dietary habits were not significant. Urinary 1-OHP level of Spring, Summer, Autumn, and Winter were $0.21{\pm}0.12,\;0.10{\pm}0.17,\;0.16{\pm}0.12,\;0.17{\pm}0.14{\mu}g/g$ cr, respectively. The arithmetic means of urinary 1-OHP for four season tee $0.16{\pm}0.14 {\mu}g/g$ cr. There was a trend that urinary 1-OHP level of residents who dwelling in apartment were higher compared with detached home, Comparison of 1-OHP level between heating by kerosene and LPG, Much higher gas heating type than kerosene type (P<0.05). This result implies that the urinary 1-OHP can be applied as the PAHs exposure indices.

The health-related habits, dietary behaviors and health status as well as the relationships between the health-related habits and dietary behaviors and the health status were investigated in the subjects of the middle aged(20 male and 50 female with the average age of 56.4$\pm$6.1) and the elderly(15 male and 15 female with the average of 68.4$\pm$3.6) living in Chonju. The survey included the personal interview using questionnaires, anthropometric measurement and biochemical tests in December, 1998. The breakfast irregularity was shown in 5.7% of male and 10.8% of female. The consumption of generally lightly salted foods was practiced in half of the subjects. The prevalence of smoking and alcohol drinking were shown in 20% and 31.4% of male group respectively. As judged by their body mass indices(BMI), none of the subjects was belong to the obesity group. However, the considerable degree of overweight was found in female subjects. The upper-body obesity was more prevalent in female compared to male group. The percentages of the anemic subjects as judged by WHO hemoglobin level were found to be relatively high specially for female(26.2%). The blood pressure, serum total cholesterol and LDL-cholesterol determination showed that the middle aged males and the elderly females tend to have higher levels compared to the different age bracket subjects from two-way ANOVA. Therefore, it can be assumed that the middle aged males and the elderly females are under the greater risk than the other groups. The analysis of the relationships between health-related habits and dietary behavior, and the health status showed that the regularity of breakfast, the consumption of lightly salted foods, the frequency of exercise and the alcohol drinking pattern influenced the city dwellers and the risk-related health habits as well as dietary behavior.

This study analysed the mercury concentration in the hair of 62 students (male : 21, female : 41) of D university in Najusi, Jeon-Nam area. Also, questionnaire, which developed by NIES, were completed by the students. According to the questionnaire, most of the students had a higher intake of meat than that of fish. Also, among the students, there were many smokes and many had dental treatment with amalgam. Based on the gender, female showed 1.024 ${\mu}g/g$ and male showed 0.882 ${\mu}g/g$ of the mercury concentration. This means that female students had higher level of mercury in their hair, but it was not a significant statistic difference. Comparing by the intake frequency of meat, processed food stuffs, protein foods, it shows the more they at the higher mercury concentration was observed. According to the intake frequency of fish, when the number of times they intake increased, the mercury concentration was higher. Under one time was 0.857 ${\mu}g/g$ and twice or more times were 1.152 ${\mu}g/g$, which showed a significant statistical difference (p<0.05). Depending on the Life style, the mercury concentration in the hair was high with workout, outdoor activities, and direct smoking. The mercury concentration in the hair showed no difference for whether they received amalgam treatment but the personal dietary habit and the Living condition affects strongly on the mercury concentration level.

The purpose of this study was to examine the relationships between the nutrient intake and level of depressive symptoms. A total of 5,761 subjects with depression were selected for the main data analysis from a Korean National Health and Nutrition Examination Survey, KNHANES (2016), and were divided into low depressed and high depressed groups. The data were analyzed by descriptive analysis, ${\chi}^2-test$, logistic regression, and t-test using SPSS 24.0 statistics. The results revealed significant differences in the prevalence of depression according to sex (P<0.001), age (P<0.001), income (P<0.001), and education (P<0.001). Regarding the health behavior, higher stress levels (P<0.001) and smoking habit (P<0.001) appeared to be strongly associated with high levels of depression. On the other hand, the possibility of experiencing depressive symptoms was lower when the number of walking days per week was more than 3 days (P<0.05), when the number of working days per week was more than 5 days (P<0.01), and the rate of aerobic physical activity was higher. Based on the 'Dietary Reference Intakes for Koreans 2015', the subjects in the low depression group showed better intake of energy and 22 nutrients than the high depression group.

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.

Purpose: This study was done to investigate the practice level of 14 health behaviors between male (N=139) and female (N=175) elderly and to identify the barriers to each health behavior of elderly people in Korea. Methods: Data were collected from 314 elderly people (65yr and older) living in metropolitan, urban, and rural areas. Descriptive statistics, $x^2$-test and ordinal logistic regression were used in data analysis using the SPSS Win 15 version. Results: 1) The performances were different in some health behaviors between male and female elderly people. Male elderly showed better performances in balanced diet, regular exercise, and more than 30 min of exercise, while female elderly showed better performances in restriction of fat and cholesterol, restriction on alcohol, and smoking. There were no differences in stress management and health prevention behaviors between the two groups. 2) The common significant barriers in health behaviors of the elderly in Korea were the lack of habit and physical discomfort. However, the lack of perceived benefit was a significant barrier in male elderly. Lack of time and lack of family support were significant barriers in female elderly people in Korea. Conclusion: These results suggest that tailored strategies should be developed considering the gender difference to reduce the main barriers of each health behavior in order to improve the health status of elderly people.
