Resumo: OBJECTIVE: To estimate the prevalence and identify correlates of physical activity among adolescents. METHODS: Cross-sectional study nested within a cohort of 4,325 subjects from the city of Pelotas, Southern Brazil, aged 14-15 years in 2008. Physical activity was analyzed using three different approaches: (1) prevalence of any leisure-time physical activity; (2) prevalence of any active commuting to school; and (3) prevalence of engaging in at least 300 minutes per week of both (1) and (2) combined. Independent variables included sociodemographic, behavioral, social, and biological characteristics, and number of different leisure-time physical activites practiced. Statistical analyses were carried out using Poisson regression. RESULTS: The proportion of adolescents involved in any type of leisure-time physical activity was 75.6%, while 73.4% displayed some form of active commuting to school. Prevalence of total physical activity score (≥ 300 min/ week) was 48.2%, being greater among boys (62.6%) than among girls (34.5%). Furthermore, prevalence increased along with the number of physical activity modalities practiced (p<0.001). Factors associated with greater physical activity (leisure + commuting) at the recommended levels were: nonwhite ski acolor, having failed at school, and playing videogames. Lower socioeconomic status, more time spent on the computer, and parental physical activity were associated with the outcome only among girls. CONCLUSIONS: Less than half the adolescents reached recommended levels of physical activity, and this proportion tended to decrease among subjects with higher socioeconomic level. Associated factors were different for leisure-time and commuting. Engaging in a wide variety of physical activities should be encouraged already during childhood.

MÉTODOS: Estudo transversal aninhado em uma coorte com 4.325 indivíduos de 14-15 anos em Pelotas, RS, em 2008. A atividade física foi analisada por meio de três diferentes abordagens: 1) prevalência de alguma atividade física de lazer; 2) prevalência de algum deslocamento ativo para a escola; 3) prevalência de engajamento em pelo menos 300 minutos por semana da combinação de ambos (1 e 2). Variáveis independentes incluíram características demográfcas, socioeconômicas, comportamentais, sociais e biológicas e número de atividades físicas praticadas no tempo de lazer. As análises estatísticas foram feitas pela regressão de Poisson. RESULTADOS: A proporção de adolescentes envolvidos em alguma atividade física de lazer foi 75,6%, enquanto 73,4% apresentou alguma forma de deslocamento ativo para a escola. A prevalência de atividade física total (escore ≥ 300 min/sem) foi 48,2%, sendo maior para os meninos (62,6%) do que para as meninas (34,5%). Além disso, a prevalência aumentou de acordo com o número de atividades físicas praticadas (p < 0,001). Os fatores associados à maior prática de atividade física (lazer + deslocamento) nos níveis recomendados foram: cor de pele não-branca, ter repetido de ano na escola e jogar videogame. As variáveis menor nível socioeconômico, maior tempo de uso de computador e atividade física dos pais estiveram associadas ao desfecho apenas entre as meninas. CONCLUSÕES: Menos da metade dos adolescentes atingiu as recomendações para a prática de atividade física, e essa proporção tende a diminuir entre os sujeitos de maior nível socioeconômico. Os fatores associados diferiram entre lazer e deslocamento. Engajamento em uma ampla variedade de atividades físicas deve ser encorajado desde a infância.2012-12-12T17:21:10Z2012-12-12T17:21:10Z2010info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfDUMITH, Samuel de Carvalho et al.
