Resumo
ObjectivesTo examine the efficacy of aerobic fitness thresholds in predicting weight status and cardiovascular disease risk (CVD) in young people.MethodsA cross‐sectional school‐based study was conducted on 414 Portuguese young people (235 girls and 179 boys) aged 10–16 years (Mean age ± SD = 13.6 ± 1. 8 years). Height and mass were assessed to determine body mass index (BMI). The 20m multistage shuttle‐fitness test (MSFT) was used as an estimate of aerobic fitness. Capillary blood sampling was used to determine: total cholesterol, triglycerides, high‐, and low‐density lipoprotein. These were combined with measures of systolic blood pressure as z‐scores and summed to create a CVD risk score.ResultsAnalysis of covariance, controlling for sexual maturation, indicated a significant main effect for BMI as a result of fitness category (P = 0.0001). When applied to CVD risk data, there was no difference between 'fit' and 'unfit' grioups (P = 0.136). Subsequent receiver operating curve (ROC) analysis indicated signifciant diagnostic accuracy of 20mMSFT performance for boys and girls (both P = 0.0001) with subsequent cut‐offs of estimated VO2 peak of 49.5 ml kg−1 min−1 for girls and 47.7 ml kg−1 min−1 for boys. When applied to BMI and CVD risk data, there was a significant main effect as a result of fitness category for BMI (P = 0.0001) and CVD risk score (P = 0.0001).ConclusionsRecently established cut‐points proposed by Boddy et al. (Boddy et al. [2012]: PLoS One 7(9): e45755) show validity in distinguishing between weight status but not CVD risk in Portuguese young people. Alternative ROC generated cut points significantly predicted BMI and CVD risk in this sample. Am. J. Hum. Biol. 25:751–755, 2013. © 2013 Wiley Periodicals, Inc.
