Abstract

This study investigated the associations between the level of physical activity with sociodemographic, environmental and academic factors of adolescents. Two thousand five hundred and forty-five adolescents aged between 14 and 18 from Florianópolis and neighboring cities participated in this study. The short version of the International Physical Activity Questionnaire (IPAQ) was used. The prevalence of inactive adolescents was 48.6%, being higher among females (53.9%). For girls, physical inactivity was associated with the lack of appropriate and free places for physical activity (OR = 1.30 95% CI 1.05 to 1.82), with no influence of other variables. For boys who had no professional activity (OR = 1.54 95% CI 1.14 to 2.08), less educated mothers (OR = 0.41 95% CI 0.27 to 0.75), or graduate mothers (OR = 0.35 95% CI 0,17- 0,73), living in major cities (OR = 1.64 95% CI 1.17 to 2.31) and low socioeconomic classification when compared to the average (OR = 0.69 95% CI 0.49 to 0.97) were more prone to physical inactivity. It was observed that the socio-demographic variables were associated with the inactive behavior of boys and environmental variables were associated with the physical inactivity of girls. Among the academic factors, only having to repeat a year was associated with inactivity, and only for girls.

Este estudo investigou as associações entre o nível de atividade física com os fatores sociodemográficos, ambientais e escolares de adolescentes. Participaram 2.545 jovens de 14 a 18 anos dos municípios da Grande Florianópolis. Foi utilizada a versão curta do Questionário Internacional de Atividade Física (IPAQ). A prevalência de jovens inativos foi de 48,6%, sendo maior no sexo feminino (53,9%). Para as moças, a inatividade física esteve associada com a falta de lugares apropriados e gratuitos para a prática de atividade física (OR = 1,30 IC95%1,05-1,82), independente da influência das outras variáveis. Já para os rapazes, aqueles que não possuíam atividade profissional (OR = 1,54 IC95%1,14-2,08), mães de menor instrução (OR = 0,41 IC95% 0,27-0,75) ou mães com ensino superior (OR = 0,35 IC95% 0,17- 0,73), pertencentes a cidades de grande porte (OR = 1,64 IC95%1,17-2,31) e classificação socioeconômica baixa quando comparada à média (OR = 0,69 IC95% 0,49-0,97), apresentaram maior chance de inatividade física. Observou-se que as variáveis sociodemográficas estiveram associadas ao comportamento inativo dos rapazes e às variáveis ambientais se associaram a inatividade física das moças. Já dentre os fatores escolares, apenas a reprovação escolar foi associada com inatividade, e somente para as moças.
