Epidemiology of the metabolic syndrome among Korean children and adolescents

Metabolic syndrome and suicidal ideation in korean based on the 2010 korean national health and nutrition examination survey

The aim of this study was to investigate the relationship between metabolic syndrome and suicidal ideation in Korean. This study was based on the 2010 Korean National Health and Nutrition Examination Survey. A questionnaire was used to measure suicidal ideation and physical examination was performed to measure waist circumference, blood pressure, fasting glucose, cholesterol and triglyceride levels. Complex samples logistic regression was performed to estimate the relationship between metabolic syndrome and suicidal ideation among adults and adolescents. Subjects with metabolic syndrome were more likely to have suicidal ideation in adult. There would be essential needs to evaluate suicidal ideation in adult with metabolic syndrome and to follow up suicidal ideation in adolescents with metabolic syndrome.

The metabolic syndrome and body composition in childhood cancer survivors

Purpose

Long-term survivors of childhood cancer appear to have an increased risk for the metabolic syndrome, subsequent type 2 diabetes and cardiovascular disease in adulthood compared to healthy children. The purpose of this study was to investigate the frequency of the metabolic syndrome and associated factors in childhood cancer survivors at a single center in Korea.

Methods

We performed a retrospective review of medical records of 98 childhood cancer survivors who were diagnosed and completed anticancer treatment at Samsung Medical Center, Seoul, Korea between Jan. 1996 and Dec. 2007. Parameters of metabolic syndrome were evaluated between Jan. 2008 and Dec. 2009. Clinical and biochemical findings including body fat percentage were analyzed.

Results

A total of 19 (19.4%) patients had the metabolic syndrome. The median body fat percentage was 31.5%. The body mass index and waist circumference were positively correlated with the cranial irradiation dose (r=0.38, P<0.001 and r=0.44, P<0.00, respectively). Sixty-one (62.2%) patients had at least one abnormal lipid value. The triglyceride showed significant positive correlation with the body fat percentage (r=0.26, P=0.03). The high density lipoprotein cholesterol showed significant negative correlation with the percent body fat (r=-0.26, P=0.03).

Conclusion

Childhood cancer survivors should have thorough metabolic evaluation including measurement of body fat percentage even if they are not obese. A better understanding of the determinants of the metabolic syndrome during adolescence might provide preventive interventions for improving health outcomes in adulthood.

Prevalence of metabolic syndrome and associated risk factors among Korean adolescents: analysis from the Korean national survey

The aim of this study was to estimate the prevalence of metabolic syndrome (MS) and to identify the associated risk factors of MS among Korean adolescents. A total of 606 adolescents aged 12 to 18 years from the third Korea National Health and Nutrition Examination Survey (KNHNES) in 2005 participated in a community-based and cross-sectional survey through face-to-face interviews. The authors defined pediatric MS using the modified National Cholesterol Educational Program-Adult Treatment Panel III. The overall weighted prevalence of MS in Korean adolescents was 13.0% (15.4% boys, 10.0% girls). In multivariate logistic regression analysis, boys, adolescents with body mass index (BMI) greater than the 85th percentile, and adolescents who watched TV for more than 2 hours per day were significantly more likely to have MS. These findings suggest that lifestyle modification focusing on weight control by increasing physical activity is important for the prevention of MS in adolescents.
