Abstract

It was our objective to estimate the prevalence and associated factors with low aerobic fitness among adolescents. A cross-sectional study was conducted with 575 subjects aged 11-17 years from Criciúma, SC, Brazil. The 9-minute walk/run test was used to assess aerobic fitness. Sociodemographic data and daily habits were collected using a self-administered questionnaire. Anthropometric evaluation was also performed to calculate anthropometric indicators of obesity. The Chi-square test and the binary logistic regression were used. The prevalence of low aerobic fitness in boys aged 11-13 years was 46.0% and in girls 40.5% (p<0.05), while in boys aged 14-17 years, the prevalence was 59.6% and in girls 46.6 % (p<0.05). Boys aged 11-13 (OR: 5.04; 95% CI: 1.93 – 13.17) and those aged 14-17 years (OR:3.78; 95% CI: 1.90 – 7.52) and girls aged 11-13 years (OR: 3.62; 95% CI: 1.24 – 10.52) from private schools were about four times more likely of having low aerobic fitness compared to those from public schools. Girls aged 11-13 years (OR: 2.40; 95% CI: 1.04 – 5.54) with inadequate sleep were more likely to have low aerobic fitness than those with adequate sleep. High prevalence of low aerobic fitness was associated with private schools and inadequate sleep in both sexes.
