The mother's obesity-related stress and it's association with obesity, food intake, and physical activity in both mothers and their children were determined. Based on self-reports from 470 mothers, obesity stress of mothers were scored by using a five-point Likert scale; only low and high stress scores were used in this study. The perceptions of mothers' weights and their children's weights, mothers' Body Mass Indices (BMI), and preschoolers' Weight-Length Indices (WLI)(%) were also determined. The obesity stress of mothers was significantly associated with the mothers' BMI (high stress: $23.5{\pm}2.4$ vs. low stress: $19.6{\pm}1.7$, p<0.05), but not with their children's obesity. Mothers with a high obesity stress reported a higher percentage of family history of obesity (62.1% vs. 38.3%, p<0.001) than mothers with low obesity stress. Compared to mothers with low obesity stress, mothers with high stress had lower correct-perceptions about their weights (p<0.05) but higher correct-perceptions for their children's weights. Almost 54.5% of mothers with high stress reported watching television 2 or more extra hours per day, compared with 32.2% of mothers with low stress (p<0.05). More children of mothers with high stress had long hours of daily TV viewing than children of mothers with low stress (36.0% vs. 15.3%, $X^2=10.491$, p<0.05). Mothers with high stress reported lower intake of protein-rich foods (p=0.01) and vegetables (p=0.039), but a higher intake of snacks (p=0.009), compared to mothers with low stress. More children of mothers with high stress reported eating high fat snacks or high sugar snacks everyday, but this was not statistically significant. In conclusion, high obesity stress in mothers were greatly associated with their BMI and their inactive life style, including long TV viewing hours per day and unbalanced food intakes, which can lead their children becoming inactive and obese. Special attention is recommended for overstressed mothers and their children, especially those who enjoy long hours of TV viewing.

Black vinegar has been traditionally used for supplemental flavoring on food, and commercialized beverages. Here, to investigate the effects on in vivo anti-obesity complications of black vinegar produced with herbal extracts, we evaluated on the biochemical effects of high-fat diet (HFD) induced mice compared to control fed ones. After a 84-day experiment HFD mice had higher (P < 0.05) weight gains, relative abdominal-fat pads, blood glucose level, serum/liver lipids, and serum nephron indices. Continuous oral treatment of three different concentration of herbal black vinegar (HBV; stock, 2-fold, and 4-fold diluted solution) to HFD mice showed that HBV reduced marked obesity (fat depositions, adipocyte hypertrophy), hyperglycemia, hyperlipidemia (serum total cholesterol, triglyceride, LDL-cholesterol levels), enhanced liver function (AST/ALT), and kidney function (BUN, creatine levels), respectively. Thus, HBV is expected to serve as an efficient and functional supplemental ingredients or food for the alleviation of obesity syndrome.

To compare physique classification by body consciousness and anthropometric index, 83 students were chosen from May to June 1998. Anthropometry including weight and height were measured and food frequency was examined by questionnaires. The results are as follows; 1) Average age of the subjects is 20.7, height 160.8cm and weight 51.4 kg. 2) All anthropometric indices and body fat percentage are highly correlated and all anthropometric indices show high and positive correlation with weight, but negative correlation with height. 3) The 55.4-75.9% of subjects were normal range by criteria of BMI and RI respectively, but the 40% of subjects were obese range by the self-consciousness of leanness/obesity. 4) The lean group was thinner in trunk and extremities, taller and lighter than the obese group. 5) When we investigated the groups classified by the body consciousness, the significant differences were found in the physical measurements related with feeling about self-obesity.

Purpose: Using food labels has been related to healthy eating habits and positive health outcomes. The purpose of this study is to describe the prevalence of food labels utilization and the association between food label use and obesity related factors. Methods: We conducted a self-reported population-based survey including health behaviors, 24-hour recalls, measurements of body mass indices with 6,266 Koreans aged 10 or older. ${\chi}^2$-test and ANOVA examined differences in demographic factors, health behavioral factors, and nutrition factors in tandem with food label use categories. Multivariates logistic regression was used to estimate association between food label use and obesity factors. Results: The percentages of food label users and non-users who perceive food labels were 21.8% and 48.5% respectively. In the multivariate logistic regression, food label use had significant positive associations with women, age, income, education attainment, and subjective obesity. After adjusting for socioeconomic factors and dietetic treatments, the positive associations between food label use and subjective obesity, weight control, and subjective obesity with objective normal weight remained. Conclusion: In order to improve eating habits and weight management, the obesity population that does not use food labels needs to receive proper nutrition education including food choice and body image correction.

The aim of this study was to provide fundamental data by degree of obesity which was necessary to nutritional education for the formation of right eating and dietary guideline by researching food habits of children. In order to achieve this purpose, a survey was conducted on 3, 4, 5, 6th grade of students from 4 schools in S and G city in Jeolla-Namdo. The results was as follows. There were 384(44.4%) students were normal weight, 193(22.3) were overweight, and 287(33.2) were low weight by obesity indices. Comparing the student's subjective health condition among the degree of obesity, 40.4% of overweight recognized they were healthy, 30.1% recognized ordinary, and 57.1% of lean recognized they were healthy, 34.5% recognized ordinary. It was turned out that most students who were overweight and lean recognized healthy and normal. Family was reported to be the most impact factor on student's diet habits, and then Multimedia such as TV seemed to have a effect on overweight and lean students, but nutrition teachers had a direct influence on normal weight students. The most thing which eating habits for a reform was unbalanced diet. The students in this research have breakfast everyday and regularly. Regarding dietary attitudes, overweight group enjoyed eating healthy food more than normal and low body weight group did, and tried to eat what they have never eaten before. In conclusion, it's necessary for elementary school students that increase the control ability of self perceived health condition with education for good eating habit and grasp their condition themselves through the nutrition education in school.

The purpose of this study was to investigate the relationship of body mass index with environmental and dietary factors including nutrition knowledge, and nutrition attitude of Korean adolescents. Anthropometric measurements, questionnaire responses, and 24-hour dietary records of 531 elementary, 543 middle, and 533 high school students residing in Seoul and Kyunggi-do were collected. Data was analysed using SAS computer program. The results are as follows. Mean BMI of elementary school boys was higher than that of girls. However, there were no significant differences in mean BMI between sexes both in middle and high school students. Calcium and iron consumption were lowest among elementary and middle school students, respectively when the intake was expressed as a percentage of the Korean RDA. Energy, protein, vitamin A, vitamin B$_1$, vitamin B$_2$, niacin, and vitamin C intakes(% RDA) were lowest among high school students. The factors influencing BMI of elementary students were BMI of the parents in boys, and BMI of the father in girls. In middle school students, energy intake, fathers BMI, mothers nutrition knowledge and students BMI, and nutrition knowledge were related to the obesity indices of boys, while fathers and mothers BMI were related to the mean obesity index of girls. In high school students, nutrition knowledge and mothers nutrition attitude were related to the obesity index of boys, while BMI of parents was related to the obesity index of girls. In conclusion, mothers and fathers BMI were the most common factors influencing the BMI of these adolescents. Although these results can not determine if food behaviour directly affects BMI, it may influence the BMIs of family members, and therefore nutrition education to keep normal weight and desiradle food habits should be emphasized. More systematic studies to investigate the cause-effect relations of these factors are required.

The purpose of this study was to compare the validity of obesity indices among the body mass index (BMI), waist circumference (WC), and body fat percentage (BF%), and to determine which is the most useful index to predict the risk of chronic diseases of elderly people. This study was conducted as a cross-sectional study at welfare centers in Seoul. The total number of subjects was 261 (68 men and 193 women) with age ${\geq}60$ years. The distribution of obesity using 3 obesity indices in the subjects with hypertension, diabetes, or arthritis was BF%>WC>BMI in elderly men and WC>BF%>BMI in elderly women. In elderly women, odds ratios (ORs) for hypertension in BMI and WC quartiles were significantly increased in quartile 2 and 3 (p<0.05). The ORs for hypertension, hyperlipidemia, and arthritis in BF% quartiles were significantly increased in quartile 3 and 4 (p<0.05). The BF% was sensitive obesity index for predicting the occurrence of chronic disease in men, and the WC was sensitive index in women. Our results suggested maintaining BMI less than $23.5kg/m^2$, WC less than 82 cm, and BF less than 35% in order to prevent chronic diseases in elderly women.

Objectives: This study analyzed literature published in Korea using Tae-eumin prescriptions and herbs for obesity for future research. Methods: We conducted a computerized search at journal web sites and manual searches. A total of 25 sites were included. Obesity, obese, over weight, herb, herbal, taeum, taeyuem, and taeeum were selected keywords and they were combined properly. Results:A total of 28 studies were analyzed. The percentage of clinical and case report studies was 35.7% and experimental studies 64.3%. The most frequently used prescription was Taeeumjowui-tang (太陰調胃湯) and herbs were Raphani semen(蘿葍子) and Platycodon grandiflorum(桔梗). Weight (kg), body mass index (BMI) and side effects and symptoms were used as indices in clinical and case report studies. Weight, weight gain percentage and blood serum lipid profiles were frequently used as indices in experimental studies. Conclusion: Further well-designed randomized controlled studies and clinical reports of side effects and symptoms are needed for development of obesity studies for Tae-eumin prescriptions.

This analysis was performed to investigate the relationship between nutrition and anthropometric indices using the data from a cross-sectional survey of a large national sample, '98 Korean national health and nutrition examination survey. Subjects were selected by stratified multistage probability sampling design and completed dietary questionnares including food intakes for one day by 24-hour recall method. For this analysis, 6566 subjects were selected by age(over 20 years old). For anthropometry, height, weight, and waist- and hip- circumference were measured. They were classified by body mass index(BMI, weight(Kg)/$height^2 $($m^2 $)) and waist-hip ratio(WHR, waist circumference(Cm)/hip circumference(Cm)). The nutrients intake of subjects were compared with the recommended daily allowances(RDA). Mean adequacy ratio(MAR) was calculated. Mean heights, weights, BMIs were higher in the groups with nutrient intake over 125% of RDA than the lower intake groups for most nutrients. However, Mean WHR was the highest in the groups with nutrient intake under 75% of RDA for most nutrients excluding iron intake of women aged 20-64 years. Among women aged 20-64 years, means of MAR were 0.71 for obese individuals(BMI>30), 0.72 for subjects with underweight(BMI<18.5), and 0.76 for subjects with normal weight(18.5$\leq$BMI<25). Normal subjects has statistically significantly higher MAR than those of other groups. However, among elderly people aged over 65 years, obese group had the highest MAR, 0.68. Women with abdominal obesity(WHR>0.9) had lower MAR, 0.71 than those with normal weight(MAR=0.76). From these results, obesity and abdominal obesity seems to be the results of malnutrition including both undernutrition and overnutrition rather than simple problem of excess energy intake. Obesity in elderly people needs to be handled differently from adults.

Background: This study investigated the relationship between depressive symptoms and physical fitness, obesity indices, and vitamin D status in office workers. Methods: The subjects were 514 adults with more 30 years of experience as office workers in the city of Seoul. Lifestyle risk factors, obesity indices, physical fitness, and serum vitamin D levels were assessed with a standardized protocol. The Beck Depression Inventory (BDI) was used to assess depression status. Vitamin D status was assessed by measuring serum 25-hydroxyvitamin D concentrations. Based on the BDI scores, participants were classified into no depression (ND, $BDI{\leq}9$), mild depression (MiD, $10{\leq}BDI{\leq}15$), and moderate depression (MoD, $16{\leq}BDI{\leq}23$) groups. Results: Compared with the high cardiorespriatory fitness group, the low cardiorespiratory fitness (men OR=2.618, women OR=1.596) an middle cardiorespiratory fitness group (men OR=1.256, women OR=1.110) had significantly higher odds ratio for having depressive symptoms, even after adjustment for age, hypertension, diabetes, hyperlipidemia, cardiovascular disease, alcohol intake, smoking, body mass index (BMI), percent body fat (%BF), and waist circumference (WC). Compared with the insufficient or deficient vitamin D group , the sufficient vitamin D group had significantly lower odds ratios for having depressive symptoms (men OR=0.121, women OR=0.114), even after adjustment for age, hypertension, diabetes, hyperlipidemia, cardiovascular disease, alcohol intake, smoking, BMI, %BF, and WC. Conclusion: Vitamin D supplementation and outdoor activities should be key components of a lifestyle intervention against office workers' depression.
