Underreporting patterns by the level of obesity have not been fully assessed yet. The purpose of this study was to examine the differential underreporting patterns on cardiovascular risk factor, macronutrient, and food group intakes by the level of Body Mass Index (BMI). We analyzed cross-sectional baseline nutritional survey data from the population-based longitudinal study, the Healthy Women Study (HWS) cohort. Study subjects included 538 healthy premenopausal women participating in the HWS. Nutrient and food group intakes were assessed by the one-day 24-hour dietary recall and a semi-quantitative food frequency questionnaire, respectively. The ratio of reported energy intake (EI) to estimated basal metabolic rate (BMR) was used as a measure of relative energy reporting status and categorized into tertiles. Overweight group ($BMI{\geq}25kg/m^2$) had a higher ratio of EI to BMR (EI/BMR) than normal weight group ($BMI<25kg/m^2$). Normal weight and overweight groups showed similar patterns in cardiovascular risk factors, nutrient intake, and food group intake by the EI/BMR. Fat and saturated fat intakes as a nutrient density were positively associated with the EI/BMR. Proportion of women who reported higher consumption (${\geq}4\;times/wk$) of sugar/candy, cream and red meat groups was greater in higher tertiles of the EI/BMR in both BMI groups. Our findings suggest similar patterns of underreporting of cardiovascular risk factors, and macronutrient and food group intakes in both normal and overweight women.

Objectives: This study was conducted to estimate medical expenditure attributable to overweight and obesity in adults with hypertension, diabetes and dyslipidemia using Korea National Health and Nutrition Examination survey data and Korea National Health Corporation data. Methods: The medical expenditure of hypertension, diabetes and dyslipidemia related to overweight and obesity were composed of inpatient care costs, outpatient care costs and medication costs. The population attributable risk (PAR) of overweight and obesity was calculated from national representative data of Korea such as the National Health Insurance Corporation cohort data and 2005 Korea National Health and Nutrition Examination survey data. Results: The medical expenditure attributable to overweight and obesity of hypertension were 456 billion won (men : 215 billion won, women : 241 billion won). Those of diabetes were 282 billion won (men : 148 billion won, women : 135 billion won), and of dyslipidemia were 17 billion won (men : 9 billion won, women : 8 billion won). Consequently, these costs corresponded to 33.3% of total medical expenditure due to hypertension, diabetes and dyslipidemia. Conclusions: We found a substantial medical expenditure due to overweight and obesity of hypertension, diabetes and dyslipidemia were very high. In order to reduce these costs, effective national strategies for prevention and management of overweight and obesity should be established and implemented.
The purpose of this study is to investigate the relationship between eating disorders, body image, and self-esteem of high school girls. Data were analysed by SPSS/PC using frequency, percentage, mean, standard deviation, ANOVA, & Pearson correlation coefficient. The results of this study are as follows. 1. The mean of body weight and height of the subjects were 52.49kg, 161.16cm. As defined by BMI, the obese subjects were very rare(2.1%) and the rest(97.9%) was under weight or normal. 2. More than 53% of the subjects perceived their weight as overweight, while 2.1% of the women were obese as defined by BMI. Ninety-three percent of the subjects were not satisfied with their body shape. 3. For the need for weight control, subject's own judgement(70.8%) was the highest percentage. High percentages of the women reported a decrease in the amount of eating(22.9%), and an increase in the amount of exercise(52.8%) as effective methods of weight control. 4. The total mean score of anorexia nervosa was higher than bulimia nervosa. 5. The scores of eating disorders did not differ significantly by the BMI score : The score of eating disorders was highest in the group os the overweight. 6. The score s of body image did not differ significantly by the BMI score : The score of body image was highest in the group of the overweight. 7. No significant difference was found in over all self esteem scores according to the BMI scores. 8. There was high positive correlation between BMI and eating disorders(r=.2158, p=.0094), between self-esteem and body image(r=.4288, p=.0001), and positive correlation between BMI and self-esteem(r=.1569, p=.0604), and between BMI and body image(r=.1354, p=.1056).

This study is supposed to offer data related to whether circulation training(aerobic and anaerobic exercise) focused on overweight women has positive effects on reducing fat and increasing muscles for middle-aged women. This study aims to investigate how the circulation training effect overweight middle-aged women's female hormone, blood lipid, which offers basic data of exercise program to keep the overweight middle-aged women healthy. Participants for the study are 30 to 45-year-women who were willing to take part in a M Sports Diet Program in G gu, B metropolitan city, did not have any disease. They were 29 overweight women and showed more than 30% of body fat percentage. Female hormone, blood lipid were measured twice before and in 12 weeks after exercise. The results obtained from this study are given as in the following. Although estrogen has significantly increased after the circulation training, there was no meaningful difference from the control group. After 12-weeks-circulation training, even though there were no meaningful differences. before the training, the circulation training group was significantly higher than the control group. Although TC has significantly decreased after the circulation training, there was no meaningful difference from the control group. the circulation training group was significantly lower than the control group. Even though TG was no significantly decreased after the circulation training, there was no significantly difference from the control group. the circulation training group was significantly lower than the control group. Even though HDL-C has significantly increased after the circulation training, there was no meaningful difference from the control group. the circulation training group was significantly higher than the control group. Even though LDL-C has significantly decreased after the circulation training, there was no significantly difference from the control group. the circulation training group was significantly lower than the control group.
Consuming regular meals has been studied in relation to better health, while higher regularity of eating-out has been linked to obesity. This study examined whether acculturation was associated with regularity of meals, eating-out, and overweight in Korean Americans. Pre-tested questionnaires were mailed to a U.S. national sample with Korean American surnames, and 55% of the deliverable sample responded, producing 356 usable questionnaires. Acculturation was measured using a two-culture matrix model and Gordon's theoretical work, and showed there were three distinct groups (acculturated, bicultural, and traditional). Only 36% reported that they regularly ate three meals a day. Breakfast was the least frequent meal of the day with 43% reporting eating breakfast everyday. More than half (58%) reported that they usually eat out or get take-out food at least once a week. After controlling for age, sex, income, education, and working status, higher acculturation was related to greater regularity of eating-out, but not meal regularity. A total of 28% of men and 6% of women were overweight (BMI>25), and there were significant and positive relationships between body weight status and acculturation in men but not women. However, no significant relationships between frequency of meals and eating-out and overweight status were present. This study did not find significant relationships of meal regularity and eating-out with body weight, however, given the positive relationship between acculturation and eating-out among the subjects and the well-established relationship between eating-out and obesity, nutrition education about skipping meals and eating-for Korean Americans may be useful to prevent such relationships from developing.

Objectives : Physical activity is known as beneficial to mental health like decreasing depression and stress. In this study, we tried to find out the relationship between body composition, stress, depression, and self-esteem with physical activity level. Methods : International Physical Activity Questionnaire(IPAQ)-short form, SRRS(Social readjustment rating scale), SRI(Stress response index), and BDI(Beck's depression index), SES(Self-esteem scale) were given to peri-menopausal women aged 45-55 and BMI$\geq$23kg/m2. They were given written consent and this study is performed under the permission of institutional review board of Kyung Hee East-west Neo Medical Center. Results : The mean of physical activity of total subjects was 2406MET-min/week(n=42). The physical activity of overweight(23kg/m2$\leq$BMI<25kg/m2) and obese(BMI$\geq$25kg/m2) permimenopausal women was 1428MET-min/week and 2970MET-min/week(p<0.05) respectively. When three levels of physical activity pattern(inactive, minimally active, and HEPA(Health-enhancing physical activity) active) was analyzed, all of them were heavily relied on the activity intensities of walking. The scores of BDI, SRRS, and SRI were lower and that of SES were higher in HEPA active group, not showing statical significance. Anger(subscale of SRI) measures were lower and SES measures were higher in HEPA active group than others among overweight women(p<0.05). Conclusions : The level of physical activity of peri-menopausal women was on the average, but the vigorous activity is thought to be necessary. The HEPA active group showed lower depression, stress and higher self-esteem than minimally active and inactive group.
The principal objective of this study was to assess the weight control behavior, body shape satisfaction, and obesity stress depending on the degree of obesity in college students who applied for a weight control program. The average BMI of the participants was $21.4\;kg/m^2$ which was in the normal range, and 76.3% of the participants were of normal body weight. Ideal BMI in this participant was $18.1\;kg/m^2$, which is in the underweight range. In terms of body perception, participants generally overestimated their body weight. The overweight and normal weight groups were less satisfied with their body shape than was the underweight group. The overweight group also expressed fears of showing their bodies to others. Additionally, the overweight and normal groups exhibited higher obesity stress than the underweight group. 97.0% of participants were interested in weight control as a way to improve their appearance. They usually obtained their weight control information from the internet and mass media. More than 80% of participants had weight control experience, having undergone weight control attempts for duration of less than a month. However, after the discontinuation of weight control efforts, these participants regained the weight. As a consequence, they were generally unsatisfied with the outcomes of weight control programs. This study demonstrated that the college women who had applied for the weight control program were unsatisfied with their body shape owing to distorted notions of the ideal body shape, and these women had generally undertaken frequent efforts to control their body weights. These results underline the importance of educating college-aged women on proper body perception and the maintenance of healthy body weight and shape.

The enhancement of the human body fat reduction of conjugated linoleic acid (CLA) with the supplementation of $\gamma$-oryzanol (OZ) was investigated on overweight Korean women (n=51, BMI> 23). Subjects were divided into 4 groups of control, CLA, glyceride form of CLA (GCLA), and CLA plus OZ (CLA-OZ). The soft-gel capsule (500 mg) was used to deliver control (500 mg olive oil), CLA (500 mg CLA), GCLA (500 mg GCLA) and CLA-OZ (500 mg CLA plus 50 mg OZ). Three capsules were taken twice a day for 12 weeks. The CLA-OZ supplementation reduced 1.35% body fat that was 0.34% enhancement against CLA supplementation. As considered subject variations, CLA-OZ reduced body fat ranged from 7.9% to -2.7%, equivalent to 5.6 kg loss to 0.7 kg gain in body fat mass, against CLA. The CLA-OZ reduced body weight and body mass index (BMI), relative to control, but the reductions by CLA-OZ were not different from those by CLA and GCLA. All biochemical markers analyzed for safty were not significantly different within or between groups and were within the normal range. The CLA-OZ supplementation significantly reduced blood pressure, as compared to the supplementation of CLA, GCLA and control. These results suggest that OZ could be a useful ingredient to mix with CLA for the reduction of human body fat.
Obesity is characterized by increased storage of fatty acids in an adipose tissue and closely associated with the development of insulin resistance and cardiovascular diseases (CVD) through secretion of adipokines. This study was done to compare serum insulin, leptin, adiponectin and high sensitivity C-reactive protein (hs-CRP) levels according to body masss index (BMI) in Korean adult women aged 19 to 50. In addition, we examined the association of BMI, serum lipids and Homa-IR with serum adiponectin, leptin and hs-CRP levels. The subjects were divided into 3 groups by their BMI, normal weight (BMI ${\leq}$ 22.9, n = 30), overweight (23.0 ${\leq}$ BMI ${\leq}$ 24.9, n = 71) and obese group (25.0 ${\leq}$ BMI, n = 59). Serum levels of total-cholesterol, TG, and LDL-cholesterol were significantly higher in obese group than in normal weight group. LDL/HDL ratio and AI were significantly higher in obese group than in normal or overweight group. Fasting serum levels of glucose and insulin and Homa-IR as a marker of insulin resistance were significantly higher in obese group than in overweight group. Serum leptin level was significantly higher in obese group while serum adiponectin level was significantly lower in obese group compared to other two groups. hs-CRP was significantly increased in obese group. Correlation data show that serum adiponectin level was positively correlated with serum HDLcholesterol level and was negatively correlated with BMI, WC, TG, LDL-cholesterol, Homa-IR, hs-CRP and leptin. In addition, serum leptin level was positively correlated with BMI, WC, glucose, insulin, Homa-IR and hs-CRP. These results might imply that the regulation of key adipokines such as adiponectin might be a strategy for the prevention or treatment of obesity-associated diseases such as diabetes and CVD.

Objectives: This study was conducted to investigate the effect of low sodium diet education program on dietary habits, diet quality, and measures of obesity in overweight or obese middle-aged women. Methods: Subjects were 81 individuals aged 45 years or over, who completed an 8-week nutrition education. The subjects were divided into a normal group (N = 30) and an overweight-obese group (N = 51) according to the BMI. The effects were evaluated by anthropometric measurement, biochemical analysis, questionnaire, and diet records before and after the program. Results: Overweight-obese group showed significant decreases in weight (p < 0.0001), BMI (p < 0.0001), percent of body fat (p = 0.0087), waist circumference (p < 0.0001), systolic (p = 0.0003) and diastolic blood pressure (p = 0.0261). Nutrients intakes were not different between the two groups and only sodium intake was decreased after education. Total score of general dietary habits, dietary behavior related to sodium intake, dietary diversity score (DDS), diet variety score (DVS), and diet quality index-international (DQI-I) were improved in both groups compared to the baseline. Overweight-obese group showed significant improvement in 'having fruits everyday', 'having fish everyday', 'trying to eat many kinds of food', 'eating less broth when eating soup, stew, and noodles', 'eating less kimchi and salt-fermented vegetable', and 'propensity to think that dishes should be pretty seasoned'. In addition, moderation of empty calories food (p = 0.0064) and macronutrient ratio (p = 0.0004) were improved in the overweigh-obese group, but in the normal group, the results did not reach statistical significance. Conclusions: These results suggested that low sodium diet education program may contribute to obesity management by improving diet quality and dietary habits in middle-aged women.
