The purpose of this study was to compare the anthropometry and nutrition knowledge, food behaviour and lifestyle of women college students with different obesity indexes. The subjects were 251 women college students who were randomly selected from Kunsan National University. The height, body weight, soft/lean mass, fat mass, percentage of body fat, and fat distribution were measured, and health-related lifestyle habits were evaluated based on questionnaires. The subjects were assigned to one of the following groups based on their Body Mass Index (BMI) : underweight, normal weight and overweight. The results were as follows. Their body weight, soft/lean mass, fat mass, percentage of body fat, and fat distribution were significantly higher in the overweight subjects when compared to the underweight or normal weight subjects. Standard of living, self-recognition of health status and duration of exercise were significantly correlated with their BMIs. Self-satisfaction with body weight decreased as the BMI increased. Most subjects had poor habits such as skipping meals and lack of exercises. The overweight and the underweight groups skipped meals more frequently than the normal weight group. There were no significant differences in the scores on the nutritional knowledge and the dietary behaviour of the subjects with different BMIs. Therefore, proper nutritional education on regular meals and intervention are required if women college students are to have normal weights and healthy lifestyles.

Data from the 2001 Korea Health and Nutrition Examination Survey, a nationally representative, cross-sectional survey, were analyzed to assess prevalence of health intended food use overall and in relation to socio-demographic and lifestyle characteristics. Health intended food were classified into four broadly defined categories: vitamin and mineral supplements, health aid food, animal protein based restorative food and medicinal plants. Thirty three percent of adults aged 20 years or older reported taking health intended food in the past year : twenty four percent took vitamin or mineral supplements and medicinal plants were taken by 17 % of adults, health aid food by 15% and animal protein based restorative food by 6%. In multivariate logistic regression, female gender, older age, more education, regular exercise and non smoking were associated with greater use of vitamin or mineral supplements. Dietary quality was significantly associated with use of vitamin or mineral supplements or health aid food but not with use of medicinal plants or animal protein based restorative foods. Obese persons were less likely to take vitamin or mineral supplements. These findings suggest that epidemiologic studies of diet, demographic or lifestyle and health take health intended food use into account because of high prevalence of use of the food by the population and differential use of the food by socio-demographic and lifestyle characteristics.

Selenium is an antioxidant trace element linked to cardiovascular disease and cancer. Although diet is a major source, relatively little else is known about independent determinants of selenium levels in free-living humans. In this study, we aimed to investigate the independent demographic. lifestyle, and dietary determinants of selenium levels in 1,997 men and 1,905 women in two large prospective U.S. cohorts. Toenail selenium levels were quantified using neutron activation analysis. Diet, geographic residence, demographic, and environmental factors were assessed by validated self-administered questionnaires. Multivariate generalized linear models were conducted to assess the independent relations of these factors with toenail selenium levels, correcting for measurement error in the diet. In multi variable-adjusted analyses, independent predictors of higher selenium were male gender (6.3% higher levels); living in West and Northern-Midwest U.S. regions (8.9% and 7.4% higher than Southern-Midwest regions, respectively); consumption of beef and bread products (between 0.7 - 2.5% higher per daily serving); and selenium supplement use (6.9% higher than non-users); whereas cigarette smoking (5-10% lower than never smokers), older age (0.6% lower per 5 years), and consumption of eggs, white rice, dairy products, coffee, and alcohol (between 0.1 to 2.0% lower per daily serving) were associated with lower selenium. Multiple dietary and non-dietary factors independently predicted selenium levels, suggesting that both consumption and non-dietary processes (e.g.. related to oxidant status) may affect levels. Significant geographic variation in selenium levels exists in the US.

According to Sa-Sang constitution, people can be classified into 4 types, Tae-Yang-In, Tae-Eum-In, So-Yang-In, and So-Eum-In. 1he purpose of this study was to examine any significance between types of Sa-Sang constitution and dietary factors. Physical and constitutional examinations as well as a questionnaire survey were conducted on a group of 483 college students. Among the group of 483 college students, only 428 subjects were determined to have identical constitution through both the questionnaire survey and Korean traditional medical doctors' inquiries. Of 428 subjects, $29.7\%$ were determined to be Tae-Eum-Ins; $35.5\%$ were identified as So-Yang-Ins; $34.8\%$ were classified as So-Eum-Ins. Tae-Eum-Ins showed a statistically significant difference in BMI and higher smoking rate in comparison with groups of So-Yang-Ins and So-Eum-Ins. So-Eum-Ins had a tendency to take vegetables and fruits more often but they had lower preferences for balanced diets. Tae-Eum-Ins showed higher propensity to eat a visible fat protein. In terms of degrees of doneness of meat, So-Yang-Ins showed a higher tendency to prefer well-broiled meat Tae-Eum-Ins also tended to have significantly higher iron, potassium, sodium, vitamin $B_1$, niacin, $\beta$-carotene and vitamin E in their diet So-Eum-Ins had significantly lower intakes of protein, phosphorous, and folate. Considering the fact that most chronic degenerative diseases could be developed by any lifestyle factors, it is necessary to conduct educational programs about lifestyles including dietary habits for maintaining good health; On the basis of the results of this study, it is expected that the scientific, objective and accurate diet information depending upon individual's type of constitution will be provided.

This study aims to determine the association between obesity-related behaviors (dietary practices, physical activity and body image) and body weight status among adolescents. A total of 382 adolescents (187 males and 195 females) aged 13 to 15 years in Kajang, Selangor participated in this study. Majority of the respondents were Malays (56.0%), followed by Chinese (30.1%) and Indians (13.9%). Dietary practices, physical activity and body image of the adolescents were assessed through the eating behaviors questionnaire, two-day dietary record, two-day physical activity record and multi-dimensional body image scale (MBIS), respectively. Body weight and height were measured by trained researchers. The prevalence of overweight and obesity (19.5%) was about twice the prevalence of underweight (10.5%). About two-thirds of the respondents (72.3%) skipped at least one meal and half of them (56.2%) snacked between meals with a mean energy intake of $1,641{\pm}452$ kcal/day. More than half of the respondents (56.8%) were practicing sedentary lifestyle with a mean energy expenditure of $1,631{\pm}573$ kcal per day. Energy intake (r = 0.153, P < 0.05), physical activity (r = 0.463, P < 0.01) and body image (r = 0.424, P < 0.01) were correlated with BMI. However, meal skipping, snacking and energy expenditure per kg body weight were not associated with body weight status. Multiple linear regression analysis showed that body image, physical activity and energy intake contributed significantly in explaining body weight status of the adolescents. In short, overweight and obesity were likely to be associated not only with energy intake and physical activity, but also body image. Hence, promoting healthy eating, active lifestyle and positive body image should be incorporated in future obesity prevention programmes in adolescents.

The purpose of this study is to analyze the impact of dietary lifestyles and demographic characteristics on the Brand image of restaurants with Nutritional labeling to provide basic marketing data for establishing differentiated Brand image strategies for restaurant businesses. To that end, the SPSS21.0 (ver.) program, frequency analysis, descriptive statistics, factor analysis, reliability analysis, correlation analysis, and multiple linear regression analysis were conducted to verify the hypothesis. As a result, the Brand image of restaurants with Nutritional labeling improved as the metropolitan area sought safety, non-capital area sought taste, males sought health, and females sought safety. In terms of age, it was analyzed that as more people in their 20s sought taste, those their 30s and 40s sought safety, and both married and unmarried people sought safety, the Brand image of restaurants with Nutritional labeling improved. In other words, it could be seen that people with Dietary lifestyles who pursued health and safety had positive images of restaurants with Nutritional labeling regardless of residential area, age, gender, marital status, or whether they had children.

BACKGROUND/OBJECTIVES: The Seoul Metabolic Syndrome Management (SMESY) program is a 1-yr lifestyle modification program targeting metabolic syndrome (MetS) in Seoul residents. This study investigated the associations between adherence to dietary guidelines and MetS among the SMESY program participants. SUBJECTS/METHODS: Data of 54,385 participants aged 20-64 yrs who completed the SMESY program in 2015, had information on adherence to dietary guidelines, and were not medicated for diabetes, hypertension, or dyslipidemia were analyzed. Participants underwent MetS screening and completed a lifestyle questionnaire including adherence to 10 dietary guidelines before and after participation. Participants were classified according to the number of MetS risk factors at baseline (MetS group, ≥ 3; risk group, 1-2; healthy group, none). Adherence to dietary guidelines was determined from the number of "yes" responses regarding the fulfillment of each guideline on ≥ 5 days/week. Multiple logistic regression was used to evaluate associations between newly diagnosed MetS and changes in adherence to dietary guidelines. RESULTS: In the MetS group, MetS prevalence decreased after the SMESY program (men, -41.9%p; women, -48.7%p), and all risk factors were significantly improved (P < 0.0001). All groups exhibited improved adherence to all dietary guidelines after participation (P < 0.0001). In the MetS group with positively changed adherence scores, the MetS prevalence decreased by -44.1%p for men and -49.5%p for women, whereas the prevalence in those with negative changes decreased by -38.1%p for men and -48.6%p for women. In the risk group, those with positively changed adherence scores had significantly decreased odds ratios (ORs) for newly diagnosed MetS compared with those with negative changes (OR, 0.70; 95% confidence interval [CI], 0.61-0.80 for men; OR, 0.88; 95% CI, 0.79-0.99 for women). CONCLUSIONS: The SMESY program may effectively reduce the risk of MetS among adults with risk factors by improving adherence to dietary guidelines.

The most critical point in the assessment of adherence to dietary guidelines is the development of a practical definition for adherence, such as a dietary pattern score. The purpose of this study was to develop the Korean Diet Score (KDS) based on the Korean Food Balance Wheel and to examine the association of KDS with various lifestyle characteristics and biochemical factors. The dietary data of 5,320 subjects from the 4th Korean National Health and Nutritional Examination Survey were used for the final analysis. The food guide was composed of six food group categories; 'grain dishes', 'fish and meat dishes', 'vegetable dishes', 'fruits', 'milk' and 'oils and sugars'. Based on the recommended serving numbers for each group, the scores measuring adherence to this food guide were calculated from the dietary information from the 24-hour dietary recall questionnaire, and then its correlation with various characteristics was assessed. KDS was significantly associated with several clinical, lifestyle and socioeconomic factors as well as diagnosed disease history. The higher quintile group of KDS showed a significantly lower level in fasting blood glucose, systolic blood pressure, triglycerides, current smoking and drinking as well as higher leisure time activity, house income and education. Furthermore, the KDS quintile group of women was inversely associated with hypertension, osteoporosis and diabetes. A higher KDS quintile was characterized with a higher intake of several critical nutrients, such as Ca, Fe and vitamins as well as a desirable nutrition balance such as the ratio of macronutrients. Our results demonstrate that KDS is a beneficial tool in assessing the adherence to a healthy diet based on the Korean dietary guidelines. We suggest that KDS could be a useful indicator for evaluating the dietary balance of the Korean population.

This study was performed to determine health-related dietary and lifestyle of characteristic factors associated with sodium hyperingestion of korean adults by sexual difference. Study subjects were 30~69years (n=1,622) adults who participated in the 2010 Korean National Health and Nutrition Examination Survey (KNHANES V-1). Subjects were divided into the hyperingestion group (HG, n=1,494) and normal ingestion group (NG, n=128) by 'WHO growth standard sodium intakes(2,000mg/day)' and the relationships between Comparison of demographics and physical measurement, eating behaviors and health-related factors were analyzed. By logistic regression method, risk factors for sodium hyperingestion group revealed in this study were gender(female), number of family', 'breakfast', 'lunch', 'dinner', 'nutrition labeling use'. and In case of male, risk factors for sodium hyperingestion group were 'lunch', 'dinner', 'self-rated body image' of eating behaviors. In case of female, Which were number of family' of demographics, 'breakfast', 'lunch', 'dinner' of eating behaviors. In these results, according to different sexual aspect of sodium hyperingestion, we suggest that nutrition label use and proper nutrition intake criteria among sexual, recognition promotion campaign along with education program for repressed sodium hyperingestion related to hypertension prevention of korean adults should include eating habits improvement and demographics lifestyle modification.
