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.

Recently, obesity that is increasingly becoming a major cause of various diseases is emerging as a serious social problem. In order to solve this problem, the necessity of measurement systems for overweight management has increased. This paper is a study on the measurement system for obesity management that can offer right medical services everywhere and allways by analyzing EMG (electromyograph) of the abdomen and then checking one's health state. For analyzing EMG signals of the abdomen, algorithms for energy detection, signal feature extraction, classification and recognition are presented. This paper proposes a system that provides an appropriate an estimation on the health status by evaluating the obesity degree and muscular strength of the abdomen through the system applying these algorithms.

This study wanted to confirm the relevance between body mass index(BMI) and insulin resistance and beta-cell function based on abdominal obesity in obese middle-aged men. This study targeted 797 obese middle-aged men who had undergone health checkups at general hospitals in Gyeonggi-do from January 2018 to June 2020. There were 327 in the group with abdominal obesity and 470 in the group without abdominal obesity. Glucose(p<0.001), HbA1c(p=0.003), insulin(p<0.001), HOMA-IR(p<0.001) was different between groups. BMI was a factor affecting insulin resistance and beta cell function regardless of the with or without of abdominal obesity. BMI was associated with the onset of disease of insulin resistance and beta cell functional degradation regardless of the with or without of abdominal obesity. Therefore, it is considered necessary to manage the indicators of the BMI through exercise programs and regular checkups for health management of middle-aged obese men.

This study helps out-size consumers purchase ready-made clothes and improve fitness by classifying the lower bodies of abdomen-obese adult males in their 20s and older; in addition, it creates a size system based on each size interval of obesity type. The criteria for the 559 male subjects surveyed in this study were over $25kg/m^2$ of BMI, over 90 cm of waist, and over 0.85 waist hip ratio. The results are as follows. First, the higher the age group, the higher the degree of abdominal obesity in each age group. The degree of obesity then decreases somewhat as their age increases; however, the risk of abdominal obesity also increases. Second, 3 clusters were categorized by cluster analysis, into abdominal obesity, larger oval-type, trapezoid-type and small cylinder-type. Third, the size system establishment according to lower-body types resulted in basic body sizes and reference body sizes being different according to types even in commonly-appeared size names in the sections of respective types. The above research findings show it is necessary to understand obesity types according to waist and hip sizes that represent basic sizes and to design patterns in consideration of the characteristics of obese body shapes when lower-half body clothes are designed among obesity groups.

Background and Purpose : This study was to assess characteristics in acute stroke patients according to obesity and abdominal obesity. Methods : From1 Oct. 2005 to 31 Jul. 2007, 629 patients with a stroke were included. Patients were hospitalized within 30 days after the onset of stroke at Kyungwon University Incheon Oriental Hospital, DongGuk University International Hospital and Department of Cardiovascular and Neurologic Disease (Stroke Center), or Kyung Hee University Oriental Hospital. We investigated general characteristics preferences according to general obesity and abdominal obesity. Results : 629 acute stroke patients were included in the final analysis. Male, young age, hypertension, heart disease in the family history, hypertension in the past history, care of invalids or grandchildren and Taeumin in the Sasang constitution were higher among obese patients. Male, transient ischemic attack in the past history, smoker and Soyangin in the Sasangconstitution were higher among patients with abdominal obesity. The incidence of abdominal obesity corresponded to lower education level. Conclusions : In our study, we observed the general disposition of various characteristic distributions according to obesity and abdominal obesity in acute stroke patients.

The present study was conducted to assess the relationship between obesity and abdominal obesity and Parathyroid hormone (PTH) in adults aged 50 or older (n=3,305) using 2011 Korean National Health and Nutrition Examination Survey (KNHANES) data, which represents national data in Korea. Key study results were as follows: First, the PTH levels increased significantly with an increase in Body mass index (BMI) (p=0.003), shown by sIAD levels after adjusted the variables that affect sIAD levels (age, gender, SBP, DBP, and 25(OH)D). These were $66.25{\pm}0.89ng/dL$ for Normal weight (BMI, < $23.0kg/m^2$), $67.83{\pm}1.07 ng/dL$ for Overweight (BMI, $23.0-24.9kg/m^2$), $70.71{\pm}0.94ng/dL$ for Obesity (BMI,${\geq}25.0kg/m^2$). Second, the PTH level of abdominal obesity group ($69.30{\pm}0.80ng/dL$) was significantly higher (p=0.017) than non-abdominal obesity group ($66.63{\pm}0.74ng/dL$). In conclusion, BMI and waist measurement are positively associated with the PTH levels in Korean adults.

In this study, we investigated the improvement effect of obesity by treatment with a developed low frequency electrical stimulation system. Thirty female in their 20's as an experiment subjects divided 3 groups(control, commercialized device, developed device) were treated with electrical stimulation on abdomen for 4 weeks. The body weight, body mass index(BMI), waist-hip ratio(WHR), muscle strength, muscle(transverse abdominis(TrA), internal obliquus abdominis(IO), external obliquus abdominis(EO)), fat thickness and abdominal surface temperature were measured by electromyogram(EMG), ultrasound and digital infrared thermal image(DITI). In the result, the body weight and BMI were decreased. Subcutaneous abdominal fat were significantly reduced after 4 weeks. The muscle strength and TrA muscle thickness was increased 13.2%(p<0.05), and 35.5%, respectively. The fat thickness showed decrease in abdomen (p<0.05). Infrared measurement on abdominal surface temperature as a parameter of improvement in blood circulation was significantly increased(p<0.05). Therefore, the low frequency stimulation showed positive effects on parameters of the obesity improvement.

Objectives This study was performed to find out the characters about distribution of abdominal fat(especially superficial and deep subcutaneous fat) in obese premenopausal Korean women. Methods 39 obese premenopausal women were recruited in 2008. Anthropometry and body impedance analysis have been done and abdominal fat distribution had been assessed by computed tomography scan at the level of L4-5. Blood test and questionnaires about depression, eating attitude and physical activity were underwent. Result Abdominal total fat area, subcutaneous fat area including superficial and deep were significantly correlated with anthropometry and BIA result while visceral fat was correlated only with age and waist circumference. In blood profile, only visceral fat area was correlated with HDL cholesterol and triglyceride. And there were no correlation among questionnaires and abdominal fat. There were no difference between superficial and deep subcutaneous fat. Conclusion Abdominal subcutaneous fat including superficial and deep did not have any correlation with heart risk factor. superficial and deep subcutaneous fat had no differences with each other and they did not show any correlation with visceral fat in obese perimenopausal Korean women.

This study analyzed the body-type characteristics of 340 old-aged obese women that had been on the rise as a part of efforts to activate the silver clothing industry. The subjects were in the age range of 60-79 and met some obesity requirements, including a Rohrer Index of 1.6 or higher, a BMI of 25 or higher, and a WHR of 0.85 or higher. Old-aged obese women showed increased thickness of the torso with age, which suggests that they revealed the characteristics of regardless of gender. In other words, they became bigger in the waist and abdomen, shorter in height, slimmer in the lower body, and thicker in the torso. There are three types of obesity: Type 1 is lower-body obesity with a higher degree of obesity in the abdomen than the upper body. Type 2 is abdominal obesity with a higher degree of obesity in the upper body than in the lower body. Type 3 is whole-body obesity with balanced obesity of the whole body. As for changes to the types of obesity according to age, those who are in their sixties usually fall into the categories of upper-body and whole-body obesity, and those who are in their seventies are much more concentrated in the categories of abdominal obesity and upper-body obesity with a decreased percentage of whole-body obesity. It is apparent that the percentage of abdominal and upper-body obesity rises with age due to fat accumulation in the abdomen.
