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 is to reveal the effect of electrical stimulation of body composition in obese person. Subjects were 30s to 40s aged healthy workers(2004. 3. 8~4. 17) in the S general Hospital in Suwon and they were brought to manage obesity. Subjects were divided into control group(Female<0.85, Male<0.90) and study group(Female>0.85, Male>0.90) by WHR(waist-hip ratio) that is measured by Automatic body composition analyzer(InBody 3.0). And we divided the study group with randomized methods into group A(n=8) and group B(n=8). Then we compared and analyzed the change of muscle mass, body fat, abdominal girth, WHR, BMI(body mass index) after application of electrical stimulation, three times a week, for 30 minutes in each session with 50 Hz of pulse frequency, $20\;{\mu}s$ or $250\;{\mu}s$ of pulse duration. There was statistically meaningful decrement of body fat(p<0.05) and abdominal girth(p<0.05) but not of body weight, muscle mass, WHR and BMI in the control group after application of electrical stimulation with 50 Hz, $20\;{\mu}s$. There were meaningful change of abdominal girth(p<0.05), WHR(p<0.05) and BMI(p<0.05), but not of body weight, muscle mass and body fat after application of electrical stimulation with 50 Hz, $20\;{\mu}s$ in group A. We applied electrical stimulation with 50 Hz, $250\;{\mu}s$ in group B, then there were meaningful change of body weight(p<0.05), body fat(p<0.01), abdominal girth(p<0.01), WHR(p<0.05) and BMI(p<0.01) but not of muscle mass only. Consequently, the pulse duration is the main parameter of electrical stimulation that affect the body composition of obese person in this study and if we combined the diet control to reduce blood components we could have better result. So it would be more effective to manage localized obesity(in abdomen, thigh, upper arm, etc.) if you apply electrical stimulation considering the pulse duration.
This study was performed to compare nutrient intake, bone density, total cholesterol and blood glucose in women who lived in Taegu city. The number of subjects participated in the study was 89 and they were classified into 3 groups by age. 30.3% of the subject were in their 20-34 years of age, 37.1% were in their 35~49 years of age and 32.6% were above fifty. A dietary record method was used to assess the nutritional intake of subjects. Anthropometric measurement such as body weight, height and WHR, and blood pressure, blood glucose, cholesterol and BMD were measured. The results were as follows, mean weight, WHR, SBP, and blood glucose and total cholesterol of the subjects above 50 years old were significantly higher than those of 20-49 years of age(p<0.05). Mean bone density in calcaneus of subjects aged above fifty was lower than those of under 49 years of age(p<0.05). Weight, BMI, waist circumference, WHR and SBP were positively correlated with age(p<0.01). WHR and body fat were positively correlated with BMI(p<0.01). Waist circumference was positively correlated with SBP(p<0.01). Bone mineral density was negatively correlated with age and SBP(p<0.01). Also BMD was positively correlated with weight(p<0.05). Energy intakes was positively correlated with bone mineral density(p<0.05). Fat intakes was negatively correlated with SBP and blood glucose(p<0.05). Calcium intakes was negatively correlated with SBP(p<0.05). Ca/P ratio was negatively correlated with age(p<0.05) and WHR(p<0.01). Zinc intakes was negatively correlated with SBP and blood glucose(p<0.05). From the findings, it is suggested that the women after menopause keep the optimum body weight and good eating habits. Especially intake of good quality protein, calcium and carbohydrate seemed to be important.
Background and Purpose : The purpose of this case-control study was to show the relationship between risk factors(past medical history, BMI, WHR, smoking, drinking), warning signs(dyscinesia, sightless, dysarthria, sensory disorder, numbness, blephalospasm, facial spasm, tension) and the incidence of stroke in korean adults. Methods : 455 stroke patients were enrolled as the case group and 180 non-stroke patients as control group from Oct. 2005 to Feb. 2006. Patients were hospitalized within 2 weeks after the onset of stroke. Obesity were defined as $BMI{\geq}25kg/m2$, $WHR{\geq}0.9$ in male and $WHR{\geq}0.8$ in female. Risk factors and warning signs were obtained from personal interview. The analysis of the data was done by chi-square test. Fisher's exact test and test-sample t-test. Results : The percentage of current smokers(or current drinkers) of case group is higher significantly than that of control group. The past medical history of risk factors were found to be transient ischemic attack(p=0.0698), facial palsy(p=0.4061), hypertension(p<0.0001), hyperlipidemia(p=0.1484), DM(p<0.0001), ischemic heart disease(p=0.0093), migraine(p=0.0014) and hypochondria(p=0.2370). $WHR{\geq}0.9$ in male had a 6.696 (3.711-12.082) odds ratio, $WHR{\geq}0.8$ in female had a 1.567 (0.659-3.726) odds ratio. $BMI{\geq}25kg/m2$ had a 2.017(1.263-3.222). The dyscinesia and sensory disorder of warning signs were found to be statistical difference between case and control group. Conclusions : According to the above results, it was found that smoking, drinking, BMI, WHR, hypertension, DM, ischemic heart disease, migraine affected to the incidence of stroke.
The aim of this study was to evaluation the association between obesity and periodontitis according to the characteristics of subjects. The subjects of this study was 429 subjects aged 19 years or older from March to May, 2010. Data were analyzed with chi-square test, Multivariable logistic regression and Statistics were analyzed linear regression analysis using SPSS 18.0. WHR had dose-effect relationship with the number of sextants with periodontitis. With regard to relationships between obesity type and periodontitis depending on characteristics of objects, the WHR obesity group showed results higher than the normal group, for twice(OR: 2.24; 95% CI: 1.17-4.28) and three times or more(OR: 3.34; 95% CI: 1.53-7.27) in frequency of daily teeth brushing, 0-3 points(OR: 2.47; 95% CI: 1.09-5.59) and 4-6 points(OR: 3.99; 95% CI: 1.75-9.08) in the self-perception of stress level, and the group with 8 hours or more(OR: 4.20; 95% CI: 2.11-8.34) in the sleeping time. If anyone is judged to have obesity by WHR, we can say that the risk to have periodontitis together with it is 2.56 times more likely(95% CI: 1.58-4.13).

The purpose of this study is the investigation of park golf exercise impact on body composition and sleep. Measuring body composition was using multi-frequency impedance meter (Inbody720) for the Weight,% Body Fat, BMI, WHR. And there was using Oh,jinju(1998) as a measurement tool for sleep. Looking at changes in body composition, In the experimental groups, before the experiment body weight $60.56{\pm}6.25kg$, BMI $25.40{\pm}12.4kg/m^2$, %BodyFat $36.46{\pm}4.67%$, WHR $0.93{\pm}0.17$, after 12weeks, weight $58.3{\pm}7.16kg$, BMI $24.28{\pm}2.32kg/m^2$, %BodyFat $35.1{\pm}3.02%$, WHR $0.92{\pm}0.16$ as a significant decrease(p <.05) have appeared. After conducting an exercise program, experimental sleep score increased from 42.03 to 47.43 (increased 5.37) and control group increased from 42.48 to 43.4(increased 0.94). Between the two groups were statistically significant differences. In this study, performed 12weeks of the park golf exercise has a positive effect on body composition and sleep of the elderly.
Objects: The purpose of this case-control study was done to examine the relationship between stroke prevalence and the anthropometric indices(body mass index(BMI), modified Broca's method(Broca's index), waist circumference(WC), waist-hip ratio(WHR)), dyslipidemia, past medical history(heart disease, hypertension, diabetes mellitus(DM)), life-style factors(smoking, drinking) in Korean adults. Methods : The study group consisted of neurologically confirmed 116 stroke patients as the case group and 116 non-stroke patients as control group. Obesity were defined as $BMI{\geq}25kg/m^2,\;Broca's\;index{\geq}30%$, WC >94cm in male and WC >80cm in female, $WHR{\geq}0.9$ in male and $WHR{\geq}0.8$ in female. Oyslipidemia were defined as total $cholesterol{\geq}200mg/dl,\;triglyceride{\geq}200mg/dl,\;HDL-cholesterol {\leq}35mg/dl,\;LDL-cholesterol{\geq}160mg/dl$. Information on life-style factors and past medical history was obtained from personal interview. The analysis of the data was done by means of chi-square test(Pearson's chi-square test, Fisher's exact test) and student t-test. Results: The results were as follow. In the study group: Hypertension had a 4:05 odds ratio, Broca's $index{\geq}30%$ had a 1.98 odds ratio, WC >94cm in male had a 2.17 odds ratio, WC >80cm in female had a 2.80 odds ratio, $WHR{\geq}0.9$ in male had a 4.66 odds ratio, $WHR{\geq}0.8$ in female had a 5.35 odds ratio, but heart disease, DM, life-style factors, serum lipid and 8MI had no direct relationship with odds ratio(nonsignificant). By student t-test, risk factors for stroke were found to be total cholesterol(p=0,025), LDL-cholesterol(p=0.013), WC(p=0.000) and WHR(p=0.000). Conclusions: This study suggests that people should be advised to control hyperlitension, hyperlipidemia and obesity since these carry a risk of stroke.

This study aimed to explore the association between obesity index and heart rate variability (HRV) in college-aged male smokers. A total of 85 male college students (> 10 cigarettes per day for at least 3 years) were participated in this study. According to a standardized protocol, body mass index (BMI), percent body fat (%BF), waist circumference (WC), and waist-to-hip ratio (WHR) were taken as obesity indices. Resting r-r interval was monitored for HRV analysis as an indicator of cardiac autonomic regulation. Compared with low WHR subjects, high WHR subjects had significantly lower values of rMSSD, pNN50, HF, and SD1, suggesting decreased parasympathetic activity. No such differences in LF/HF ratio were found between the WHR-based subgroups. Bivariate correlation analysis showed that obesity indices of WC, WHR, and %BF were significantly associated with rMSSD, pNN50, HF, and SD1, with a tendency for correlation coefficient to be higher with WHR than with WC or %BF. No significant association was found between BMI and HRV parameters indicative of parasympathetic activity. This study suggest that central obesity is significantly associated with decrease in parasympathetic activation, independent of BMI as an indicator of obesity, in male college smokers.
This study was performed to find and compare the characteristics of dietary factors and obesity indices on serum lipid profiles using 407 healthy adult males that had physical examinations conducted at the general hospital located in Suwon. The subjects were divided 56.3% for the normal group, 16.7% for TG, 14.5% for TC and 12.5% for TC TG group, respectively. When comparing the blood lipid profiles to normal group, TC group was high in both total cholesterol and LDL-cholesterol, TG group was high in triglyceride and low in HDL-cholesterol, TC TG group was high in triglyceride, total cholesterol, LDL-cholesterol and low in HDL-cholesterol. In comparison of blood lipid profiles with normal group, among anthropometric factors, body weigh, BMI (Body Mass Index) and WHR (Waist Hip Ratio) showed significant differences. TC group was high in both total cholesterol and LDL-cholesterol, and TG group was high in triglyceride and low in HDL-cholesterol. TC TG group was high in triglyceride, total cholesterol and LDL-cholesterol, and was low in HDL-cholesterol. Body weigh of TG group was significantly higher than that of normal group (p<0.05). BMI and WHR of TG group and TC TG group were significantly higher than those of normal group (p<0.05). Total cholesterol was mainly related to the intake of animal lipids and alcoholic beverage. Serum triglyceride levels were closely related with lipid intake and high BMI in this group. In TC TG group, BMI and WHR were high. As well, serum LDL-cholesterol was high and HDL-cholesterol was low which indicates TC TG group had the most undesirable blood lipid profiles. Therefore, it may be necessary to manage BMI and WHR to prevent hyperlipidemia and obesity for adult males in Suwon.
The purpose of this study was to investigate the physical characteristics and instrumental activities of daily living(IADL) of the elderly (85+). The subjects were three-hundred elderly people over the age of 85, living in Kyungpook Sung-Ju area who have no problems in daily living. The survey on anthropometric measures and IADL were carried out by individual measurement and interviews using measuring devices and questionnaires. The subject group of the study was composed of 27% males and 73% females, the average age being 87 years old. Notable physical features of the subjects include considerably short statues and small physiques compared to the average Korean elder. The mean Body Mass Index(BMI) was 20.9. The average percentage of body fat in male and female was 21.7% and 29.5% respectively, and the average waist/hip ratio(WHR) was 0.9 and 0.85 respectively. The percentage of the subjects who were able to perform all the IADL was 51% in males and 25% in females. The male subjects were more capable than the females in all the IADL except for preparing meals. BMI showed positive correlations withy weight(r=699), WHR(r=0.157), body fat percentage(r=0.57), lean body mass(r=0368) and total body water(r=0.368). WHR also had positive correlation with weight(r=0.184), BMI(r=0.157), lean body mass(r=0.149) and total body water (r=0.148). Body fat percentage had a positive correlation with weight(r=0.147) and BMI(r=0.265) and total body water(r=0.265). In summary, the elderly(85+) in the Sung-Ju area had considerably smaller physiques than the average Korean elderly and showed a normal range of BMI in average. The IADL of the elderly(85+) appeared to have a positive correlation with lean body mass and total body water and a negative correlation with body fat percentage.
