RESUMO
Resumo Objetivou-se verificar a relação, a fração atribuível populacional (FAP) e a redução relativa do risco (RRR) do apoio social e autoeficácia com o nível de atividade física em escolares. Estudo transversal probabilístico com 1472 escolares de 13 a 15 anos. Foram avaliados sexo, idade, apoio social dos pais e dos amigos, autoeficácia e nível de atividade física através de questionários. Para análise dos dados utilizou-se regressão de Poisson com variância robusta, FAP e RRR, adotando p≤0,05. Foram considerados ativos 56,1% (n=826) dos escolares, sendo os meninos (68,7%) em maior proporção. O apoio social dos pais foi positivamente associado à prática de atividades física dos meninos (RP: 1,28;IC95%: 1,12-1,48; FAP=21,88) e das meninas (RP: 2,00; IC95%: 1,59-2,51; FAP=50,00). O apoio social dos amigos foi positivamente associado à prática de atividades físicas dos meninos (RP: 1,34; IC95% 1,16-1,54; FAP=25,37) e das meninas (RP: 1,32; IC95%: 1,06-1,64; FAP=24,24). A autoeficácia não se associou com atividade física. O apoio social apresentou-se associado com o nível de atividade física, e as análises da FAP indicaram que sem o elevado apoio social dos pais e amigos pode haver uma redução do nível de atividade física em adolecentes.Abstract The aim of this study was to verify the relationship, the population attributable fraction (PAF) and the relative risk reduction (RRR) of social support and self-efficacy with level of physical activity in students. Probabilistic cross-sectional study with 1,472 students aged 13-15 years. Gender, age, social support from parents and friends, self-efficacy and levels of physical activity were evaluated through questionnaires. Data analysis was performed using Poisson regression with robust variance, PAF and RRR, adopting p≤0.05. A total of 56.1% (n = 826) of students were considered active, boys (68.7%) presenting the largest proportion. Social support from parents was positively associated with physical activity in boys (PR: 1.28, 95% CI: 1.12-1.48, PAF = 21.88) and girls (PR: 2.00; 95%CI: 1.59-2.51, PAF = 50.00). Social support from friends was positively associated with physical activity in boys (PR: 1.34, 95%CI: 1.16-1.54, PAF = 25.37) and girls (PR: 1.32, 95%CI: 1.06-1.64, PAF = 24.24). Self-efficacy was not associated with physical activity. Social support was associated with levels of physical activity, and PAF indicated that the absence of high social support from parents and friends might reduce the level of physical activity in adolescents.
