title: [Domains of physical activity and education in São Paulo, Brazil: a serial cross-sectional study in 2003 and 2008].
abstract: This study aimed to estimate the prevalence of physical activity in different domains and the association with schooling, using a serial cross-sectional population-based design comparing data from two editions of a health survey in the city of São Paulo, Brazil. Participation included 1,667 adults in 2003 and 2,086 in 2008. Probabilistic sampling was performed by two-stage clusters. The long version of International Physical Activity Questionnaire (IPAQ) allowed evaluating multiple domains of physical activity. Poisson regression was used. Men were more active in their leisure time and at work and women in the home. Schooling was associated directly with leisure-time activity (2003 and 2008) and inversely with work-related physical activity (2003) for men and for women in housework. The studies showed that Brazilians with less schooling are becoming less active, so that intervention strategies should consider different educational levels. Interventions in the urban space and transportation can increase the opportunities for physical activity and broaden access by the population.
