The objective of this study was to assess the relationship between dietary sodium intake and prevalence of abdominal obesity in Korean adults. We used data from the Korea National Health and Nutrition Examination Survey V-1 and analyzed data on 4,475 Koreans (${\geq}30$ years old). Subjects were divided into three groups according to fasting plasma glucose (FPG): 1) normal (FPG <100 mg/dL), 2) pre-diabetes ($100mg/dL{\leq}FPG{\leq}125mg/dL$), and 3) diabetes (FPG ${\geq}126mg/dL$ or subjects diagnosed with diabetes). The subjects in each category were stratified by dietary sodium intake as well as index of abdominal obesity. We found that dietary sodium intake was positively correlated with waist circumference (WC) (P=0.002) and was particularly high in the pre-diabetes group. In multiple logistic regression analysis, the normal and diabetes groups showed no association between dietary sodium intake and WC, whereas the pre-diabetes group with a high sodium intake exhibited a significant association (odds ratio (OR)=1.479, P=0.029) between dietary sodium intake and WC. Further, the OR for abdominal obesity in the high sodium intake group with pre-diabetes was 1.590 after adjusting for age and sex (P=0.012). In addition, the ORs for the prevalence of abdominal obesity with fasting glucose, fasting insulin, and homeostasis model assessment of insulin resistance were significantly higher in the pre-diabetes group with high sodium intake compared with low sodium intake. Moreover, these associations were significant even after adjusting for confounding variables (model 2: age and sex; model 3: age, sex, and total energy intake). Our results suggest a strong association between sodium intake and abdominal obesity in pre-diabetes Korean adults.

This study examined the serum lipid levels according to the obesity indices, and obtained the relationship between obesity indices and serum lipid levels among adults who underwent a health checkup in a university hospital. The subjects for this study were 4,112 adults aged 18 to 77 years who underwent medical examinations at the health center of a university hospital in Daejeon city from Jan 2012 to Dec 2013. The serum lipid levels (TC, HDL-C, LDL-C, TG, AI) and obesity indices (height, weight, waist circumference, body fat rate, BMI, WHR WSR) of the study subjects were surveyed from self-recorded questionnaires and medical examination charts of the hospital. As a result, the serum lipid levels (TC, HDL-C, LDL-C, TG, AI) of the study subjects were increased significantly with higher level of obesity indices (WC, body fat rate, BMI, WHR WSR) in both sexes. The TC, LDL-C, TG, and AI showed that positive correlated with the WC, body fat rate, BMI, and WSR in both sexes, but HDL-C was negatively correlated with the WC, body fat rate, BMI, and WSR in both sexes. The above results suggest that the obesity indices and the serum lipid levels are closely related, i.e., the serum lipid levels increase with increasing obesity indices.

Purpose: To examine the effects of the aerobic exercise program on changing the body composition, blood lipids and self-esteem of the obese elderly women. Method: A total of 26 obese elderly women(%body fat: over 30%) have been selected for this research[Experimental Group(EG):13, Control Group(CG):13). Walking at a 50% intensity was administered 4 days a week for 14 weeks. The data was analyzed using the SPSS program. Result: The level of % body fat, TC, LDL-C, and %TC/HDL-C in EG was significantly lower than those of the CG after 14 weeks. In addition, the level of HDL-C and self-esteem in EG was significantly higher than those of the CG after 14 weeks. However, TG, body weight between groups didn't appear significant at the end of 14 weeks. Conclusion: The results showed that the aerobic exercise program was effective in changing body composition, blood lipids and self-esteem of the obese elderly women.

Purpose: The purpose of the study was to investigate the relationships between objective obesity, subjective obesity, body attitudes and dieting among college women. Method: The convenience sample consisted of 531 women. BMI was calculated based on self-reported weight and height. Body Attitudes Questionnaire (BAQ) was used to evaluate attitude toward women's body. Result: BMI mean score was 19.75. Based on BMI, 84.2 percent of the subjects were in a normal weight range and 0.9 percent of the subjects were obese. However, 26.9 percent of the subjects evaluated themselves as obese. Forty-one percent of the subjects were on a diet to reduce thier body weight. Body attitudes were associated with BMI and subjective obesity. BMI of the dieters was higher than that of the subjects who were not on a diet. Subjective obesity was associated with dieting. BAQ subscales except 'attractiveness' were associated with dieting. Conclusion: Many subjects were on a diet since they wanted to be thinner. Body attitudes were associated with dieting. Therefore, proper education is needed in weight management for young adult women.

Background: Recently, the prevalence of obesity (body mass index [BMI] ${\geq}25kg/m^2$) has been increasing rapidly worldwide over a short period. In Korea, the prevalence of obesity has also increased rapidly due to the rapid socio-economic development and lifestyle changes, with differing patterns according to gender. This study aimed to compare the change in obesity prevalence according to gender among the adult population in Korea using representative data, the National Health Check-up Database (NHCD), to follow-up individuals who had undergone checkups during both years in Korea (2011~2013). Methods: To analyze the changes in obesity prevalence in the recent two years, data regarding men and women who had undergone health check-ups in both two years (2011, 2013) were extracted. The final study population comprised 144,934 persons: 83,604 (58%) males and 61,330 (42%) females. Chi-square test within a univariate analysis, and the level of factor difference was verified with t-test, one-way ANOVA and multiple comparison. Results: In 2011, one out of three participants was obese (BMI ${\geq}25kg/m^2$; male, 37.7%; female, 27.3%) and more than half of the subjects were overweight (BMI ${\geq}23kg/m^2$; male, 65.6%; female, 50.4%) requiring obesity management. For the two years, the BMI of the participants significantly increased (p < .0001) and the prevalence of obesity increased among both males and females. The prevalence of obesity was higher among both genders with a longer duration of smoking, more smoking, family history of hypertension, and family history of diabetes. However, residence, income level, drinking status, psychiatric disorder, disability status and severity of disability were the opposite gender. Conclusion: In the analysis of data, the prevalence of obesity among both men and women was increasing. The degree of change in the prevalence of obesity among men and women was different in each variable. Thus, it will need to consider gender in developing health policies for obesity mediation and to provide integrated healthcare and management for those people.

Purpose: We evaluate the influence of the types of coffee beverage on obesity and abdominal obesity in Korean adults who were aged 19 years or over by using the 2013 ~ 2016 Korea National Health and Nutrition Examination Survey (KNHANES). Methods: Specific questions were asked about frequency of coffee intake, the type of coffee beverage, the addition of milk and/or sugar to coffee by using the food frequency questionnaire of the 2013 ~ 2016 KNHANES. Results: We found that coffee intake increased the prevalence of obesity and abdominal obesity. After multivariable adjustment, coffee consumption increased the risk of obesity by 1.30 (95% CI: 1.08 ~ 1.57) in the group that drank coffee twice a day, and 1.33 (95% CI: 1.11 ~ 1.60) in the people who drank coffee ${\geq}3$ times a day as compared to that of the non-coffee intake group. The risk of abdominal obesity increased to 1.27 (95% CI: 1.02 ~ 1.57) in the < 1 time/day coffee drinking group, 1.34 (95% CI: 1.08 ~ 1.66) in the 1 time/day coffee drinking group, 1.35 (95% CI: 1.09 ~ 1.67) in the 2 times/day coffee drinking group, and 1.40 (95% CI: 1.14 ~ 1.72) in the ${\geq}3$ times/day coffee drinking group as compared to that of the non-coffee drinking group. The influence of black coffee intake was different according to gender: males showed a high prevalence of abdominal obesity and females showed a high prevalence of obesity. Mixed coffee consumption increased the risk of obesity and abdominal obesity by more than 34% in men who consumed coffee more than 3 times a day and in women who consumed coffee more than 2 times per day. Conclusions: We found that coffee intake, regardless of the type of coffee, increased the prevalence of obesity and abdominal obesity. It is necessary to refrain from drinking coffee to prevent obesity.
