BACKGROUND: Physical inactivity is a predisposing factor to the onset/worsening of other cardiovascular risk factors, particularly obesity. OBJECTIVE: To determine physical activity level (PAL) and daily number of hours of TV (HTV) and the association and/or correlation of these variables with age, gender, economic class, public/private school, overweight and obesity in children and adolescents. METHODS: Cross sectional study, school-based population, public and private education, primary and secondary education. The sample was calculated based on the minimum expected prevalence of several variables, including physical inactivity. Cluster sampling. PROTOCOL: structured questionnaire, including Physical Activity for Older Children Questionnaire (PAQ-C) measurements of weight, height, body mass index (BMI) and triceps skinfold (TSF). STATISTICAL ANALYSIS: Chi-square, linear correlation. RESULTS: Among the 1,253 students, averaging 12.4 ± 2.9 years old, of which 549 were male, there was a prevalence of inactivity in 93.5%, more commonly found in female adolescents and there was no association between PAL and excess weight or body fat, soccer and dance were the most frequent activities in boys and girls, respectively; 60% of students did not have physical education classes. Average and median HTV were respectively 3.6 and 3 hours; there was a significant association between HTV and obesity and significant correlation between PAL and age (negative) and between BMI and TSF (positive). CONCLUSION: Physical inactivity is present in 93.5% of children and adolescents from Maceió. It is more commonly found among teenagers and females, with no association or correlation of this variable with excess weight or body fat; obesity was associated with ≥ 3 HTV.
