Metabolic Risk Factors, Leisure Time Physical Activity, and Nutrition in German Children and Adolescents

摘要

Purpose. We assessed the five components of the metabolic syndrome (MetS) as defined by the International Diabetes Federation (IDF) in 6040 (3158 males) youths aged 6-16 years who participated in the Praventions-Erziehungs-Programm (PEP Family Heart Study) in Nuernberg between 2000 and 2007. The purpose of this cross-sectional study was to examine associations with lifestyle habits. Results and Discussion. The prevalence of MetS was low in children (1.6%) and adolescents (2.3%). High waist circumference (WC) and low HDL-C were slightly higher in females (9.5% and 7.5%, resp.) than in males (8.8% and 5.7%, resp.). Low leisure time physical activity (LTPA) was significantly associated with low HDL-C (odds ratio [OR] 2.4; 95% CI 1.2-5.0) and inversely associated with hypertension (r = -0.146), hypertriglyceridemia (r = -0.141), and central adiposity (r = -0.258). The risk for low HDL-C (< 1.3 mmol/L) was 1.7-fold (CI 1.0-2.6) higher in youth with high (>33%) saturated fat consumption. A low polyunsaturated/saturated fat ratio (P/S ratio) was significantly associated with fasting hyperglycemia (OR 1.4; 95% CI 1.0—1.2).
