O objetivo deste estudo foi identificar a prevalência das barreiras percebidas à prática de atividade física no lazer de adolescentes, bem como analisar a possível associação das mesmas com a inatividade física no lazer. Este estudo transversal foi conduzido em 2011 e selecionou, por meio de múltiplos estágios, uma amostra representativa de 1.409 estudantes do ensino médio de escolas públicas do município de Londrina/PR. Os adolescentes responderam um questionário para coleta de dados. A relação entre inatividade física no lazer (< 300 minutos/semana) e barreiras percebidas foi analisada mediante o cálculo da razão de prevalência (RP) em modelos de regressão de Poisson. “Falta de companhia” foi a barreira mais prevalente para moças (75,8%) e rapazes (58,7%). “Preguiça” para as moças (RP: 1,21; IC95%: 1,08-1,36) e “preferência por outras atividades” para os rapazes (RP: 1,48; IC95%: 1,01-2,15), foram as barreiras mais fortemente associadas à inatividade física no lazer. Para ambos os gêneros, foi observada forte relação de dose-resposta entre número de barreiras percebidas e inatividade física no lazer. A percepção de barreiras foi associada à maior prevalência de inatividade física no lazer em adolescentes e deve, portanto, ser considerada em ações de promoção de atividade física nessa população.
The objective of this study was to identify the prevalence of perceived barriers to leisure-time physical activity in teenagers and to examine the possible association of these barriers with leisure-time physical inactivity. This cross-sectional study was conducted in 2011 and a representative sample of 1,409 high school students from public schools in the city of Londrina/Paraná was selected through multistage sampling. For data collection, the adolescents completed a questionnaire. The relationship between leisure-time physical inactivity (<300 minutes/week) and perceived barriers was analyzed by calculating the prevalence ratio (PR) in Poisson regression models. “Lack of friends company” was the most prevalent barrier for both girls (75.8%) and boys (58.7%). “Feel lazy” for girls (PR: 1.21; CI 95%: 1.08 to 1.36) and “prefer to do other things” for the boys (PR: 1.48; CI 95%: 1.01 to 2.15) were the barriers most strongly associated with leisure-time physical inactivity. For both genders, a strong dose-response relationship was observed between the number of perceived barriers and leisure-time physical inactivity. The perception of barriers was associated with a higher prevalence of leisure-time physical inactivity in adolescents and should therefore be considered in actions for promoting physical activity in this population.
