ABSTRACT
OBJECTIVE: The aim of this study was to evaluate the characteristics of the young Korean obese but metabolically healthy subjects and to identify the factors associated with metabolic health status among them. METHODS: We reviewed the medical record of South-Korea Navy soldiers at 1st marine division with routine medical examination. Within this population, we selected obese subjects whose body mass index (BMI) were more than 25 kg/m². The clinical characteristics between obese subjects with metabolically healthy and unhealthy factors were retrospectively compared. RESULTS: Of the 1,522 subjects with medical record, 319 (20.9%) subjects were identified as obese. Among them, 60 subjects (18.8%) were classified as metabolically unhealthy, whereas 259 (81.2%) subjects were metabolically healthy. Multivariate analysis revealed that higher BMI (odds ratio, OR 1.26, 95% confidence interval, CI, 1.07-1.49), higher alanine transaminase (ALT) (OR 1.03, 95% CI 1.01-1.06), and drinking alcohol (OR 3.65, 95% CI 1.02-13.02) were associated with metabolically unhealthy status in obese subjects. Meanwhile, regular physical activity was associated with metabolically healthy status in obese subjects. (OR 0.33, 95% CI 0.17-0.62) CONCLUSION: This study found that higher BMI, higher ALT, and drinking alcohol were related to metabolically unhealthy status in young Korean obese subjects; meanwhile, regular physical activity was related to metabolically healthy status.

BACKGROUND: It is known that various subtypes of obesity exist and there has been a growing interest in the various subtypes of obesity, especially in the unique "metabolically healthy but obese" subtype. The purpose of this study was to analyze the features of obese adults without metabolic complications and to provide data which can be used in strategy formation for the effective treatment of obesity. METHODS: A total of 4,561 obese adults with a BMI greater than or equal to 25 kg/m2, were recruited from a health promotion center of a university hospital. Sociodemographic and life style information were gathered by self-questionnaire. We classified them into 2 groups-one having no features (metabolically healthy obese; MHO) and the other having 1~5 features (metabolically unhealthy obese; MUHO)-using the ATP III definition for metabolic syndrome, and used the multiple logistic regression analysis to examine the association between various factors and MHO. RESULTS: Age and BMI were related with MHO independently. Adjusted odds ratio for the MHO men was 2.17 compared with women (P<0.001). Adjusted odds ratio for the MHO regular exercise group was 1.66 compared with the no exercise group (P<0.007). Additionally, those who exercised more had a greater probability of being in the MHO group. Adjusted odds ratio for the MHO in the large income group was 1.88 (P=0.007) compared with those in the small income group. As was seen with exercise, there was a direct relationship between higher income and the probability of being in the MHO group. CONCLUSION: Men compared with women, large income compared with small income, and regular exercise compared with no exercise were features of obese adults which increased their probability of being categorized as "metabolically healthy but obese".

Objective:To analyze the situation of high risk behaviors and other STI/AIDS factors among men who have sex with men(MSM)by examining the situation in a city of southwest China.Methods:A total of 267 homosexual and bisexual men were surveyed anonymously,and the results were analyzed with SPSS.Results:There was a common phenomenon during the process of MSM behaviors that numbers of MSM had more than one sexual partner and unprotected intercourse,which resulted in 21.35% incidence of STI in recent one year.Conclusion:High prevalence of STI and risky behaviors related to AIDS exist among MSM behavior.Thus,it is in urgent need to cease STI/AIDS transmission in MSM and other groups.
