This study compares salt-related dietary patterns according to sodium intake. A survey was conducted with 257 college students(130 male and 127 female students) in the Busan area. Dish Frequency Questionnaire 70(DFQ 70) was used to quantitatively estimate sodium intake. A short dish frequency questionnaire(DFQ 15) was used to screen subjects with high or low- salt intake. The sodium intake of male students based on DFQ 70 was significantly higher than that of female students(p<0.05). Sodium intake has significant negative effects on systolic and diastolic blood pressure(p<0.05). In the high-salt intake(HS) group, classified by DFQ 15, the number of male students was significantly higher than that of female students(p<0.01). The systolic blood pressure of the HS group was significantly higher than that of the low-salt intake(LS) group(p<0.05). Salt-related dietary behavior score and eating habit score for the HS group were significantly higher than those for the LS group(p<0.01). The sodium intake of the HS group based on DFQ 70 was significantly higher than that of the LS group(p<0.01). In these results, college students in Busan area showed high blood pressure and high sodium intake compared to Korean DRIs. The results indicate a need for various education programs to help college students practice a low-sodium diet.

Regarding 'mate' intake (infusion of Ilex paraguariensis herb, a staple beverage in temperate South American regions), most epidemiologic studies showed positive associations with risk of some cancers, (e.g. upper aerodigestive tract), but evidence on breast cancer (BC) risk is limited to a previous multi-site study, which reported a non significant odds ratio [OR]=0.85, 95% confidence interval [95% CI] 0.67-1.09, p for trend=0.31) for the highest quartile of intake. The present study was conducted in order to further assess associations of 'mate' intake with BC risk. We combined two databases of women belonging to public and private healthcare hospitals. The sample included 572 BC incident cases and 889 controls interviewed with a specific questionnaire featured by socio-demographic, reproductive and lifestyle variables, and a food frequency questionnaire of 64 items, also analyzing 'mate' intake (consumer status, daily intake, age at start, age at quit, duration of habit, intensity of intake). ORs and their 95%CI were calculated through unconditional logistic regression, adjusting for relevant potential confounders. The highest quartile of 'mate' intake was inversely associated with BC risk (OR=0.40, 95%CI 0.26-0.57, p for trend <0.001). Stratified analyses also displayed strong significant inverse associations for 'mate' in frequent tea drinkers (OR=0.22), high energy intake (OR=0.23), high body mass index (OR=0.29) and in postmenopausal women (OR=0.36), among other results. As conclusions, we found evidence of a significant inverse association for 'mate' intake and BC risk.

This study was carried out to analyze the effects of dietary and life-style factors on the prevalence of depression in Korea. Epidemiologic data from a nation-wide sample of 2,000 adults who were selected with the stratified random sampling method in Korea were interviewed by trained interviewers. Data were presented on the CES-D, a 20-items self-report depression symptom scale developed by the Center for Epidemiologic Studies in U.S.A. The prevalence of depression among all the respondents was 13.5%, with 13.1% in urban samples and 15.5% in rural samples. The prevalence was higher in females(15.3%) than in males(11.7%). There were highly marked differences in the prevalence of depression by sex(p<0.05), age(p<0.0001), education(p<0.001) and income(p<0.01). Respondents of 60 years and over group, the less educated group(below elementary school graduated), and the less income group(less than 400,000 won/month) reported the highest rate of depression. However subjects' occupation and residence had little relation with the prevalence of depression. Drinking and smoking habit appeared to be highly associated with depression in females(p<0.0001) but not in males. The prevalence of depression and eating behavior were highly related(p<0.005). Male respondents below 20 years, 20-29, and 60 years and over depressed group reported significantly lower energy and protein intakes compared to that of the normal group. However, in the female respondents 20-29 years and 60 years and over depressed groups showed the significantly lower energy and protein intakes compared to those of the normal groups(p<0.05), it can be concluded that the various ecological factors such as epidemiological, dietary, and health factors may affect the prevalence of depression among Korean.

Background: Epidemiology studies have shown an inconclusive relationship between phytoestrogen intake and ovarian cancer risk and there have been no relevant meta-analyses directly regarding this topic. The purpose of the present meta-analysis was therefore to investigate any association between phytoestrogen intake and ovarian cancer in detail. Materials and Methods: We conducted a search of PubMed, EMBASE, EBSCO, the Cochrane Library, CNKI and Chinese Biomedical Database (up to April 2014) using common keywords for studies that focused on phytoestrogen and ovarian cancer risk. Study-specific risk estimates (RRs) were pooled using fixed effect or random-effect models. Results: Ten epidemiologic studies were finally included in the meta-analysis. The total results indicated higher phytoestrogen intake was associated with a reduced ovarian cancer risk (RR, 0.70; 95%CI: 0.56-0.87). The association was similar in sensitivity analysis. Meta regression analysis demonstrated sources and possibly types and regions as heterogeneous factors. Subgroup analysis of types, sources and regions showed that isoflavones (RR: 0.63; 95%CI: 0.46, 0.86), soy foods (RR: 0.51; 95%CI: 0.39, 0.68) and an Asian diet (RR: 0.48; 95%CI: 0.37, 0.63) intake could reduce the incidence of ovarian cancer. Conclusions: Our findings show possible protection by phytoestrogens against ovarian cancer. We emphasize specific phytoestrogens from soy foods, but not all could reduce the risk. The habit of plentiful phytoestrogen intake by Asians is worthy to recommendation. However, we still need additional larger well designed observational studies to fully characterize underlying associations.

This study was designed to compare the dietary habits of women's university students according to residence type. The subjects were 140 females divided into four groups. The first group consisted of students residing at home with their parents (home, n=39), the second group consisted of students residing in a dormitory (dormitory, n=34), the third group consisted of students residing in a boarding house (boarding, n=36), and the fourth group consisted of self-boarding students (self-boarding, n=31). The average age was 21.9 years, and the BMI levels of the groups were $20.8kg/m^2$, $19.6kg/m^2$, $20.5kg/m^2$, and $19.7kg/m^2$, respectively. The 'home' group had higher dietary regularity than the other groups (P<0.05). The boarding group and self-boarding group were more likely to eat out and skip breakfast than the home and dormitory groups (P<0.05). All groups indicated that frequency of snacking was higher than 1 time per day, but there was no significant difference between the groups. The dormitory and boarding groups spent less time consuming meals than the other groups. In conclusion, women's university students show different dietary behaviors according to residence type. Especially, the dormitory, boarding, and self-boarding groups need to improve their dietary habits through high quality education and nutritional support at college cafeterias.

Objectives : The purpose of this study is to examine sleeping patterns and diet patterns of the children in day-care centers in Seongdong-district and to find out the relationships between those two patterns and children growth. Methods : 686 day-care center kids participated in the examination. We measured their heights and weights. We also conducted a questionnaire survey (of them) on their sleeping patterns and diet patterns. Based on the findings, we have analyzed correlations of the factors. Results : 1. We have interviewed 686 children in day-care centers in Seongdong-district. Substantial survey was conducted to 672(14 kids didn't go through regular medical checkups). Their age ranged from 4 months to 120 months and weights covered from 6.20 kg to 50.80 kg with the average of 16.97kg. Their height ranges were from 70.4cm to 140.6cm and the average was 100.76cm. 2. The survey results showed that birth-height affects children's current height. The results from the group of age over 25months and the group covering 2 to 6 years indicated that birth-height affected the current height as well. However, the result from the age group over 37 months showed that birth-height didn't relate to the current height. 3. Results from questionnaires on sleeping patterns indicate that children sleeping longer are taller than the other. Results of other questionnaires showed no substantial relations to height. 4. Results from questionnaires on diet patterns, cold food eating habit affects growth. Conclusions : According to the results above, sleeping patterns substantially affects the growth. In order to find out, however, the specific relations between them, further research would be necessary.

This study was conducted to develop a comprehensive program for improving obese children's living habits such as wearing clothing and eating, and their self-esteem. Thirteen obese elementary school children, six boys and seven girls in the 4th to 6th grade, voluntarily participated in a ten-week intervention program. During the program, the obese children filled out a checklist consisted of daily ambient temperature inside the house, weight of clothing, meal diary, time taken for physical exercise, time taken for watching TV, etc. After carrying out the program, its effect was testified and evaluated. Percent body fat of the children measured using a body composition analyzer was reduced by $1.9\%$ after the program (p<.01). Wearing behavior of clothing was positively changed in view of the high correlation between ambient temperature and clothing weight (r=-.917, p<.01). Ability of dietary self control was improved and eating time was lengthened. Self-esteem was improved in global self-worth, athletic competence, and behavior/conduct. It was suggested that active interest of the family would be helpful and that an intervention program over longer than ten week would be necessary to improve childhood obesity.

This survey was accomplished to investigate the patterns of vitamin/mineral supplements usage in the middle-aged. Eight hundred seventy two persons of middle age were chosen from various cities and rural communities in Korea. In this study, those factors affecting vitamin/mineral supplements consumption, and usage patterns were examined. In addition, vitamin and mineral intakes through supplements were calculated, and then compared with RDA. As a result, vitamin/mineral supplements were taken by 40.8% of subjects. The higher the age, education level, family income and socioeconomic status were, the higher the percentage of supplements consumption was. City-dewellers used them more often than rural-dewellers. And vitamin/mineral supplements were taken frequently in subjects who perceived their health as poor, and concerned much about health. Illness and climacteric symptoms were also related with elevated usage. However, nutritional knowledge and food habit did not affect supplements consumption. Users mostly received information about supplements from TV/radio/newspapers, of family/friends. One of the mainly cited reasons for taking supplements, next to ' to give energy', was 'to be healthier'. The four most favored supplements, in ranking order, were vitamin B-complex, vitamin E, vitamin A and Ca. Most vitamin and mineral intakes through supplements were much greater than RDA except Ca. Especially, vitamin B1 intake was the highest as 49.6$\pm$34.9 times of RDA. In conclusion, vitamin/mineral supplements used by the middle-aged in Korea was as high as those of western countries. Supplements consumption seemed to be related with affluence, poor health status, and high level of health consiousness. And supplements tended to be taken for health promotion irrespective of scientific background. Most vitamin and mineral intakes by supplements were exceeded RDA, and their intake ranges were very wide. Thus some subjects should give attention to the potential harms of megadose.

This study was conducted to analyze the relations among nutritional knowledge, nutrional attitude, eating practice and total nutritional diagnosis and also to find the influencing factors of them. The survey was done during the period from April 1990 to June 1990 and the target population were Ewha Womans University students (freshmen and senior) of whom 1,354 peoples were surveyed. The summarized results are as follows ; 1. For the teaming environment, the percentage of completion on nutritional knowledge course was 28.6% and among them the department of foods and nutrition had the highest score(100.0%) and the next was dept. of medicine (53.4%). 2. To find the relation which the nutritional knowledge, nutritional attitude, eating practice and the total nutritional diagnosis influence on one another, the multiple correlation analysis was done. The attitude and the practice were highly correlated with total nutritional diagnosis, but the correlation between nutritional knowledge and total nutrional diagnosis was not significant. The correlation between the practice and nutritional knowledge which were positively and significantly correlated with attitude respectively was positive but not significant. 3. The difference which were analyzed by department, grade and completion on knowledge course on the nutritional knowledge, attitude, eating practice were significant (p<0.01) by ANOVA. 4. The significant variables on nutritional diagnosis are the eating practice points, the grade, the knowledge course, the breakfast and the attitude ($r^2=10.3%$) by multiple regression analysis. This study has the limitation that it did not consider the environmental factors of dietary life such as dietary culture, family environment, cultural habit. Therefore important points of these dietary studies are to extend to the practical nutritional education and dietary improvement for the national health not restricted to the local area or local population.

The purpose of this study to investigate the relationship between nutrient intake and serum lipid levels in 165 healthy women in Taegu. A convenient method was to assess nutritional intake. Anthropometric measurement of body weight and height were measured and average energy expenditure calculated . The mean body mass index (BMI) was 23.4$\pm$3.1 and it was higher than the mean BMI of Korean women. Obesity rates for the study subjects were 15.7% by RBW (relative body weight : >120%) and 28.5% by BMI(body mass index) ; >25). Daily energy intake was sufficient at 106% of recommended dietary allowances and the energy percentage ration of carbohydrate , fat and protein was 68 : 18 : 14. Mean intake of vitamin A, B1 , niacin , and Ca were higher than RDA. The incidence of hypertension(>140mmHg) and hypercholoesterolemia(>240mg/dl) as 18.2% and 23.6% of the subjects, respectively . Postmenopasusal women showed significantly higher blood pressure, RBW, and ALP (alkaline phosphatase) than premenopausal women. The concentration of cholesterol and average blood pressure in the irregular meal eater group were significantly higher than in the regular meal eater group. Skipping meals and unenvendurnal distribution(no breakfast, or no lunch , and large evening meals) are associated with high total cholesterol level in this population . Especially, the atherogenic index was significantly lower in the regular meal eater group than that in irregular meal eaters. The values for serum cholesterol, triglyceride, blood pressure, BMI, and atherogenic index increased with age in middle-aged women. There was a highly significant correlation between body weight and plasma lipids. HDL -cholesterol was inversely correlated with BMI. The above dta provides valuable information for community program planning and health providers who work with individual female and adults to meet their nutrietional needs to control blood lipids.
