Mudanças na atividade física no lazer e fatores associados em adolescentes de Pernambuco, Brasil: de 2006 a 2011

Abstract

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n1p114 Leisure-time physical activity (LTPA) has important implications in promoting physical activity among young people. The present study aimed to analyze variations occurred in the 2006-2011 period in LTPA and associated factors among high school boys and girls in the state of Pernambuco, Northeastern Brazil. A cross-sectional schoolbased and statewide survey was conducted in 2006 (n = 4,207) and 2011 (n = 6,264), and samples of adolescents (14-19 years) were compared. Data were collected through a questionnaire. The practice of LTPA was obtained by the question “Do you perform regularly, some kind of physical activity in your free time?” Poisson regression was used (confidence interval (CI) 95%) in crude and adjusted analyses stratified by gender. From 2006 to 2011, there was stability in the proportion of adolescents practicing LTPA both among boys (77.5% versus 78.9%) and girls (51.2%, versus 54.0%). The weekly frequency of physical education classes was directly associated with LTPA both in girls and boys, regardless of the survey year. Age, marital status, grade and computer use were significantly associated with LTPA, but there were distinctions between genders and surveys. In conclusion, there was a temporal variation between 2006 and 2011, but the reduction or increment in LTPA practice varied according to stratification of subgroups of adolescents. In general, physical education class was a factor that remained associated with LTPA in the investigated period.

Correlatos da não participação nas aulas de Educação Física entre escolares brasileiros nas cinco regiões do Brasil

“…O nível insuficiente de AF no lazer foi correlato da não participação nas aulas de EFI entre escolares das cinco regiões do Brasil. Esse resultado reforça evidência já identificada em estudo anterior com amostra de adolescentes nordestinos 8 , que mostrou maior propensão de escolares insuficientemente ativos no lazer não participarem nas aulas de EFI. Sabe-se que as aulas de EFI podem ser uma importante fonte de AF para os estudantes, principalmente entre as meninas 39 .…”

“…Além disso, não participar das aulas de EFI apresenta associação com comportamentos de risco à saúde, como sentimento de solidão 6 , nível de AF insuficiente 5 e comportamento sedentário (CS) 7 . Em nível local e regional, estudos prévios mostraram que algumas características sociodemográficas 5,[8][9][10][11][12] , ambiental 9 e motivacional 13,14 podem ser correlatos da participação ou não nas aulas de EFI.…”
