This study divides subjects into people with metabolically healthy obesity and those with metabolically unhealthy obesity to identify the MONW and MHO prevalence adults with obesity. Participants in the sixth Korea National Health and Nutrition Examination Survey conducted from 2008-2010 were selected as the subjects, and an analysis of complex survey samples was conducted with them. In order to determine the prevalence rate of MONW as well as MHO, it would categorized MONW as of result 2 of 6 NCEP APTIII diagnostic criteria and categorized as MHO 1 of 6 diagnostic criteria. i. According to Body Mass Index and Body Fat Percentage standard the participants classify as following results: Normal Weight 2,531(26.7%), NWO 4,264(44.9%), Obesity(27.4%). ii. The prevalence of MONW and MOH are 1,393(14.7%) and 36(9.9%), respectively. iii. Group of MHO and OB’s Body Fat Percentage and Body Mass Index are significantly higher than group of MHO and NW. The group of MONW and OB’s HOMA-IR, FBS, HTN, TG, HDL-C values are significantly higher than group of MHO and NW. iv. In order of MONW appears as HDL-C> HOMA-IR> HTN> FBS> WC and MHO appears following order HTN> HDL-C> HOMA-IR> FBS> TG. Body mass index which does not reflect the characteristics of body fat appeared inability to perform a exact risk assessment of risks of obesity. Since groups of MONW and MHO have difference prevalence rate result according to each different standards, would need further follow up study.

This study was identified the differences in social factors and frequency of physical activity and nutrition intake by classifying them into groups of four groups according to the NCEP-ATPⅢ data the sixth of the Korea National Health Nutrition(2013-2015) survey data. Both the male and female subjects of MONW, MUO groups are a higher age than the MHNW and MHO groups. The education level of males was higher than BMI 25 ㎏ / ㎡ group, and the lower education level of females was not healthy. Male smokers showed a decrease in HDL-C, higher neutral fat and blood pressure, while female had lower drinking rates in the MONW and MUO groups. Physical activity shows that both males and females are significantly less athletic than the three groups. MHO group, MUO group is deliberately participating in the exercise, but the MONW group of normal weight feel the need for physical activity. Therefore, it is necessary to actively participate in an education system to improve the MONW group. Metabolic disorders arise from environmental factors such as educational levels, smoking, drinking, physical activity, and diet, and these environmental factors have affected metabolic disorders.

The aim of this study was to investigate the prevalence of Metabolic Syndrome and its components by sex, year, and obesity in Korean Children and Adolescents. The Metabolic Syndrome was defined using the criteria of IDF(International Diabetes Federation) in Children and Adolescents aged 10 to 19 years who have participated in the KNHANES in 2007 (n=512), 2008 (n=1105), 2009 (n=1191) and 2010 (n=923). The combined prevalence of metabolic syndrome in Korean Children and Adolescents was 3.1% in 2007, 1.2% in 2008, 1.3% in 2009, 1.0% in 2010. The Korean Children and Adolescents has not significantly changed 2007 to 2010. The prevalence of metabolic syndrome was highest in obese Children and Adolescents. To find the optimal, maximal sensitivity and specificity for BMI, waist circumference, the ROC (Receiver output curve) analysis of cut-off points against Fasting Blood Glucose (100 mg/dl) and Triglyceride (150 mg/dl). BMI 85 percentile was the best cut-off levels for determining the subjects with Fasting Blood Glucose over 100mg/dl and Triglyceride over 150 mg/dl. Waist Circumference 75 percentile was the best cut-off levels for determining the subjects with Fasting Blood Glucose over 100 mg/dl and Triglyceride over 150 mg/dl.

The purpose of this study was to compare and analyze body composition and subcutaneous fat distribution in both sex of adolescents drawn from East Asia region. To achieve this purposes, a total of 3,205 adolescents 10-15 years old were selected and measured weight and height. Subcutaneous fat index was calculated by using body composition, body circumference, subcutaneous fat distribution values and Frisancho`s equations. South Korea and China showed higher significant level of height whereas Japan was lowest in four countries statistically. Percent body fat was higher in South Korea and Taiwan. If a man`s upper leg in South Korea and China were higher than in Japan and Taiwan, the Taiwanese women was higher than in the three countries. Arm circumference in men than in Japan, the three countries was high, women in South Korea than in Japan and Taiwan, respectively. WHR in men than in Taiwan, the three countries were higher, women were not statistically significant. Subcutaneous fat thickness showed a statistically South Korea and Taiwan. Arm muscle area in China was significantly higher than the three countries. Including the most commonly used measure of obesity, BMI, we found that, South Korea and Taiwan had significantly more body fat, body size and fat distribution than their counterparts. This result demonstrates that the proper nutrition management and lifestyle should be given by both individual and national level not only to address imbalance between ingestion and consumption, but also to help set healthy lifelong body composition.

A new syndrome named Normal Weight Obesity (NWO) has attracted much attention in obesity-related researches. NWO i s a normal B ody Mass I ndex (BMI) a ssociated with a l arge p roportion of % Body Fat(%BF). Previously, NWO was known as a problem associated with aging. However, recent years, it has appeared to many young women. Lookism is the largest cause. Lookism has been shown to spread in our society, excessive diet and irregulareating habits, was supposed to lead to results, such as body weight regulation of in an unusual way. The purpose of this study was to find the prevalence of NWO, and the eating and exercise behaviors of Korean university women. We studied 422 volunteers, 138 were interviewed. 140 university women had bioelectrical impedance analysis to estimate body composition. All the participants filled out the Questionnaire that eating and exercise behavior. The percentage of Standard was 48.6%, NWO was 32.0% and Obesity is 10%. Interestingly, significant differences between Standard and NOW in exercise behaviors (p<.001). But, there were no significantly different in eating behaviors (p<.001). In contrast, both of eating and exercise behaviors were significantly different between Standard and Obesity (p<.01). As expected, NWO and Obesity were significant differences eating Behavior only (p<.05). The findings of the study represent important directions for the future planning of intervention programs designed to prevent NWO. Exercise interventions are warranted to prevent NWO in university women.

The purpose of the study was to provide basic information on improvement in the athletes` performance and nutrition education by measurement of their body composition before and after the strength training. In addition, the study investigated the nutritional status of the students. Important observations and conclusions of the study follow: In terms of body composition changes before and after strength training, male canoeists showed a statistically significant decrease in weight(p<.005), body mass index (BMI, p<.001) and body fat, while there were no statistically significant changes among female canoeists. The average energy intake and caloric intake per kilogram of body weight (kcal/kg) of male athletes was 5,344.6 kcal and 86.1 kcal/kg, respectively, while that of female athletes was 4,332.3kcal and 72.7kcal/kg. The ratio of carbohydrates to lipids to proteins was 62: 22: 16 for male athletes and 59: 24: 17 for female athletes. The mean carbohydrate intake per kilogram of body weight was 13.2g/kg/day for males and 10.7g/kg/day for females. In addition, the mean protein intake per kilogram of body weight was 3.3g/kg/day for males and 3.0g/kg/day for females. As a result, it was estimated that carbohydrate and protein intake of male and female athletes was adequate. The male caloric intake from snacks was 542kcal on average and the female intake was 610kcal on average. An analysis of snack-eating patterns showed that milk was the most frequently consumed item, followed by chicken, eggs and potatoes. Both male and female canoeists were found to have a sufficient intake greater than the recommended dietary allowances(RDAs) for all nutrients.
