Metabolic Syndrome in Adolescents: a Cross-sectional Study
نویسندگان
چکیده
Background: There is a substantial body of evidence that in adults, physical inactivity or low cardiorespiratory fitness levels are strongly associated with the development of metabolic syndrome. Although this association has been studied extensively in adults, little is known adolescents. The aim of this study was to analyze the association between physical activity and cardiorespiratory fitness levels with the metabolic syndrome in Brazilian adolescents. Methods: A random sample of 223 girls (mean age, 14.4±1.6 years) and 233 boys (mean age, 14.6±1.6 years) was selected for the study. Physical activity level was determined by Bouchard Three-day physical activity record. Cardiorespiratory fitness was estimated by the Leger 20-meter shuttle run test. The metabolic syndrome components assessed included waist circumference, blood pressure, HDL-cholesterol, triglycerides, and fasting plasma glucose. Independent Student t-tests were utilized to compare the genders groups, and the association between physical activity and VO2máx and the presence of metabolic syndrome was calculate using logistic regression models adjusted for age and sex. Results: A high prevalence of the metabolic syndrome was observed in sedentary adolescents (males, 9%; females, 7.2%) and adolescents with low cardiorespiratory fitness levels (males, 13.9%; females, 8.6%). Significant relationships were found between metabolic syndrome with low cardiorespiratory fitness levels (OR: 3.0 [1.13-7.94]). Conclusion: The prevalence of metabolic syndrome is high among adolescents who are sedentary and those with low fitness levels. Prevention strategies for the metabolic syndrome should concentrate on enhancing fitness levels early in life.
