Objectives : The purpose of this study was to determine what is useful index of abdominal visceral fat area among Korean obese adolescents. Methods : 35 obese adolescents who had visited Kirin Oriental Hospital from August 2004 to May 2006 were included in the study. Weight, height, waist and hip circumferences were measured. Abdominal visceral fat areas at L4-5 level were measured by computed tomography. The subjects were divided into two groups, according to sex. In each group, we investigated the correlation among waist circumference, waist/hip ratio, waist/height ratio, obesity degree and abdominal visceral fat area and evaluated that which one of these kinds of indices is the most useful predictor for visceral fat area in Korean obese adolescents. Results : There were significant correlation between waist circumference, waist/hip ratio, waist/height ratio and obesity index in both group. In boys waist/hip ratio had correlation with abdominal visceral fat area and in girls obesity index had significant correlation with abdominal visceral fat area. Conclusions : Our study suggests that waist/hip ratio in boys, obesity degree in girls can be a relatively good parameter for predicting abdominal visceral fat area.

Objectives : To determine obesity for the screening of individuals at high risk of coronary heart disease in urban areas. Methods : Data were obtained from 4,137 adults between 19 and 85 years of age (2,372 males, 1,765 females), not recognized as taking medicines for cardiovascular diseases, who underwent a health check-up at the health promotion center of university hospitals in cities between Jan. 2003 and Dec. 2004. The variables studied were divided into two broad categories, and their relationships examined. obesity indices and risk factors for coronary heart disease. To reveal the relation between each of the obesity indices and the proportion of individuals at risk of coronary heart disease, the obesity indices were stratified and odds ratios obtained after age adjustment. Results : From a gender comparison of anthropometric measures, men were found to have significantly greater heights, weights, and waist and hip circumferences than women. From a gender comparison by the obesity indices, women were found to have significantly higher BMI, %Fat, waist to hip and waist to stature ratios than men. As obesity indices, the waist to stature ratio and the waist circumference were strongly correlated with coronary risk factors, both in men and women. The age-adjusted odds ratio of coronary risk factors increased significantly with increasing waist circumference, BMI, %fat, waist to hip and waist to stature ratios, and were highest specifically for the waist to stature ratio and the waist circumference. Conclusions : The study results showed that the waist to stature ratio and the waist circumference, as obesity indices, were most closely correlated with coronary risk factors. It is suggested that the waist to stature ratio and, specifically, the waist circumference can be effectively used in the field of health management for screening those with high levels of coronary risk factors.

This study established a lower garment sizing system for abdominal obesity adult women aged 30-59 based on 277 females selected from the 7th Size Korean Anthropometric survey. The criteria for subjects in this study were over 25 kg/㎡ of the BMI, over 85 cm of waist, and over 0.8 waist hip ratio. The results are as follows. The lower body analysis of abdominal obesity adult women showed that average circumference items were larger than the ordinary size, and the average length items were smaller. The standard deviation was applied around the average values of waist circumference and hip circumference for the suggestion of a lower garment sizing system for abdominal obesity adult women. The interval between the designation was ±1.5 cm with a waist circumference of 100 cm and ±2.5 cm with an average hip circumference of 100 cm. We established 13 designation sections in consideration of the cover ratio and cover efficiency. The cover ratio in the 13 nominal sections was 71.5%. The segmental distribution rate presented in the results will also be useful for production planning in specific sizes that helped enable rational production.

Objective: The purposes of this study are to know the relations of abdominal obesity and ischemic stroke and to know what index could represent the abdominal obesity appropriately. Methods. We have done case-control study and recruited 97 ischemic stroke patients and 117 controls. Case is matched by control by individual matching. All participants had questionnaire, interview and then were examined waist-hip ratio, waist circumference and body mass index. Results : WC, WHR and Hypertension history had differences in two groups, case and control groups. But BMI and other factors weren't significant. According to Quartile of Waist Circumference, the two groups had the differences in hypertension history, diabetes history, smoking status, WHR, BMI, and weight and in the Quartile of Waist-Hip Ratio Quartile, past history of hypertension and diabetes, WC, BMI and weight had the significances. Sex, Age Adjusted and Multivariate Odds Ratio (95% Confidence Interval) of WC Quartile are 2.083, 1.628, 4.491 and 4.418, 4.964, 12.306, and in WHR, the Ors are 2.252, 5.743, 15.776 and 2.632, 8.918, 23.596. Conclusions: We knew from these results that abdominal obesity is very important risk factor of ischemic stroke and WHR more than WC is a good indicator of abdominal obesity, so we should reduce the WHR to prevent of ischemic stroke.

This study was aimed to investigate whether abdominal obesity is associated with non-insulin dependednt diabetes. The distribution of body fat patterns was observed in 181 female patients with diabetes, aged 33 to 83 years, living in the Taegu area, Korea. The following anthropometric measuremetns were made on all participants from October 1 to November 25, 1991 : weight, height ; waist and hip circumferences in standing position. The waist hip circumference ratio was used as an index of abdominal obesity. The results were as follows; 1) The mean fasting blood glucose of diabetic subjects was 145$\pm$50.3mg/dl and the mean duration of diabetes was 4.7$\pm$7.5 years. 2) Obese subjects above the ideal body weight body weight of 120% in the investigation are presently 52%, but 63% of subjects were reported to be obese in the past. The mean BMI of the subjects is 24.57$\pm$3.15 and the past mean BMI was 27.13$\pm$3.26. One year after reaching their highest body weight, 47% of the subjects developed diabetes. Two years after reaching their peak body weight, 74% of diabetic subjects developed diabetes. 3) Using the waist-hip circumference ratio, subjects beloing to the upper body obesity(WHR>0.84) were 65.5%. 4) The average daily energy intake did not differ between the obese and non-obese diabetic subjects, whether they were assessed with BMI or with RBW. 5) The average daily energy intake was higher in the upper body obesity subjects than in the lower body obesity subjects. 6) Diabetics withing the regular exercise group had lower fasting blood glucose levels than the non-regular exercise group. Exercise did not effect the RBW, BMI, and WHR. 7) The waist-to-hip circumference ratio correlated significantly in positive with waist-circumference, but did not correlated with hip-circumference. Therefore, WHR may depended on the increased accumulation of abdominal fat in female diabetics. In conclusion, these findings suggest that caloric intake is more associated with abdominal fat accumulation in diabetic women. Blood glucose concentration is independently effected by exercise, and exercise does not affect the WHR. Therefore, control of caloric intake and development of specific exercises to change the WHR seems important for controling diabetes in female subjects.

The purpose of this study was to examine the effects of an abdominal obesity management program on a woman's body composition and physiological indicators. A sample of 20 women who were 33 to 62 years old with abdominal obesity (greater than 80cm of waist circumference) participated in the program for 12 weeks. The program consisted of aerobic dance and yoga for one hour, twice a week. Their body composition was measured with BMI, body fat %, waist circumference, and waist/hip ratio. The physiological indicators were measured by systolic blood pressure, blood glucose, total cholesterol, and triglycerides before and after the program. The results showed that waist circumference, waist/hip ratio, and fasting blood glucose decreased significantly after the program. However, BMI, systolic blood pressure, and blood lipids did not change. An abdominal obesity management program with aerobic dance and yoga is partially effective in decreasing abdominal obesity. Further studies are required to replicate the study with a control group using an experimental design.

Objectives : This study was aimed to show the effect of electroacupuncture combined with magnetic acupuncture on abdominal obesity without patient dieting, exercise or use of herbal medication. Methods : Women over 85 cm in waist circumference were treated with electroacupuncture combined with magnetic acupuncture. Acupuncture points were located at the abdomen ($CV_{12}$, $CV_6$, $ST_{25}$, $ST_{21}$, $SP_{15}$, $SP_{14}$), extremities ($LI_4$, $LI_{11}$, $ST_{36}$, $ST_{44}$) and were stimulated 30 minutes with 2.1~3 Gaus, 500 Hz, tolerable strength. The Interference wave forms were by Whata 153 (Medi Lab, Korea). Two or three treatment sessions per week (five or ten sessions in total) were done. Before treatment, and after the last treatment, we measured waist circumference, hip circumference, waist hip ratio, thickness of abdominal subcutaneous fat, body weight, body mass index, body fat ratio, visceral fat area, free fat mass, body fat mass and skeletal muscle mass. We also measured the subcutaneous temperature of the abdomen($CV_{12}$, $ST_{25}(Rt)$, $ST_{25}(Lt)$, $CV_6$) by using digital infrared thermal imaging(DITI). Results : In this study, significant reductions were shown in waist circumference, hip circumference, thickness of abdominal subcutaneous fat, body weight, body mass index, body fat ratio and body fat mass. There were no significant differences in waist hip ratio, free fat mass or skeletal muscle mass. There were also significant increases of the subcutaneous temperature on $CV_{12}$, $ST_{25}(Rt)$, $ST_{25}(Lt)$. Conclusions : From the above results, electroacupuncture combined with magnetic acupuncture might be an effective treatment for abdominal obesity.

Purpose: The purpose of this study was to validate waist circumference (WC) and waist to hip ratio (WHR) corresponding to body mass index (BMI) of $25kg/m^2$ and to survey the prevalence of hypertension according to obesity in female college students. Method: Weight, height, waist and hip circumferences and blood pressure were measured for each of 286 female college students in J City, Chungbuk. Results: The subjects' mean BMI was $21.4kg/m^2$, and the estimated prevalence of obesity was 11.2%. The subjects, the 80th-90th percentile of whom had BMI exceeding $25kg/m^2$, were found to have WC of 75-78.1 cm and WHR of 0.79-0.80, respectively. Of the subjects with obesity($BMI{\geq}25kg/m^2$), 53.1% exhibited abdominal obesity ($WC{\geq}80cm$) and 40.6% had WHR over 0.80. Systolic and diastolic blood pressure were correlated with BMI, WC, and WHR. The prevalence rate of hypertension in subjects with obesity($BMI{\geq}25kg/m^2$) was 25%. Additionally, the prevalence rate of hypertension in subjects with abdominal obesity ($WC{\geq}80cm$) was 39.1%. Conclusions: Our study indicates that WC corresponding to BMI of $25kg/m^2$ in female subjects in their twenties is different from that of adult women. We also found that the prevalence rate of hypertension in subjects with abdominal obesity was high. Therefore. we suggest further studies to determine the cutoff value of WC for evaluating abdominal obesity and to investigate the long-term effects of obesity on women in their twenties.

Objective: The purpose of this research was to aid creating an effective sizing system for the vacation wear intended for Jeju's medical tourists, specifically females from the major countries including the USA, Japan, and Korea. Background: Medical tourism makes the gains of every year 40,000,000,000 dollar, every year 30% it is increasing. Thus the Jeju-do is propelling medical tourism. The body size each country is different. Consequently must set the body size standard for the women. Method: (1) It observed the body size of the Korean women of 2004 years and 2010 years. (2) It analyzed the body size of the women of the USA, China, Japan and Korea. (3) It set the sizing system of the women of the USA(ASTM), China (GB), Japan(JIS) and Korea(KS). Results: Korean adult females' height in 2010 has increased from 2004. The Waist Back Length, Waist Front Length, Arm Length etc has also increased along with the Height. The upper body has become slimmer at the same time; the Chest Circumference, Bust Circumference, and Underbust Circumference have decreased. The lower body on the other hand has become bigger: the Waist Circumference and Hip Circumference have increased. The BMI has decreased by 0.4 from 2004 - the Height has increased while Weight has decreased. The Chest Circumference and Under Bust Circumference of Korean women across all age groups have increased at a proportional rate to other parts of body; however, the rate of increase in Chest Circumference was far greater. American females(Caucasians) had the greatest ratio of waist to bust (Waist Circumference/Chest Circumference), smallest ratio of Neck Base Circumference to Bust Circumference (neck/bust). Korean females had smallest ratio of Waist Circumference to Underbust Circumference(waist/bust). As for the drop of Chest Circumference and Waist Circumference, American females had the highest and Koreans had the lowest. As for the drop of Hip Circumference and Chest Circumference, Japanese had the highest and Americans had the lowest, but Japanese women at the same time showed the A line body shapes. As for difference of Chest Circumference and Underbust Circumference, American females had the biggest(13.73) followed by Korean(11.1), Japanese(10.9) and Chinese(10.5). Conclusion: The women of the USA, China, Japan and Korea body size is different. Especially the value of the Bust Circumference - the Underbust Circumference is different. Thus, it set the sizing system(Table 8).

Purpose: This study aimed to investigate the impact of anthropometric indices of obesity (body mass index [BMI], waist circumference, waist hip ratio, and body fat percentage) on the incidence of hypertension in adults with prehypertension. Methods: A longitudinal study design using secondary data form the Korean Genome and Epidemiology Study was employed. The study included 1,838 adults with prehypertension tracked every two years from 2001 to 2018. Statistical analyses, including frequency assessments, number of cases per 1,000 person-years, log-rank tests, Kaplan-Meier curves, and Cox's proportional hazards regression, were conducted using SPSS version 25. Results: Over the observation period (15,783.6 person-years), 1,136 individuals developed hypertension. The incidence of hypertension was significantly higher in the obesity groups defined by BMI (hazard ratio [HR] = 1.33), waist circumference (HR = 1.34), waist hip ratio (HR = 1.29), and body fat percentage (HR = 1.31) compared to the non-obese group. These findings indicate an increased risk of hypertension associated with obesity as measured by these indices. Conclusion: The study underscores the importance of avoiding obesity to prevent hypertension in individuals with prehypertension. Specifically, BMI, waist circumference, waist hip circumference, and body fat percentage were identified as significant risk factors for hypertension. The results suggest the need for individualized weight control interventions, emphasizing the role of health professionals in addressing the heightened hypertension risk in this population.
