Background: Physical inactivity in transportation is negatively related to many health outcomes. However, little is known about the correlates of this condition among people living in regions of low socioeconomic level.
Methods: Cross-sectional study aimed to assess factors associated with physical inactivity in transportation among adults in the Eastern Zone of São Paulo, Brazil. Home-based interviews were conducted between May 2007 and January 2008 on a probabilistic sample of the adult population (≥18 years), totaling 368 men and 522 women. Factors associated with physical inactivity in transportation (less than 10 minutes per week of walking or cycling) were assessed using multivariate Poisson regression with hierarchical selection of variables.
Results: Physical inactivity in transportation was associated with the presence of vehicles in the household in men (PR = 2.96) and women (PR = 2.42), with linear trend for both sexes (P < .001 and P = .004, respectively), even after adjusting for age, schooling level and chronic diseases (this last factor, only among women).
Conclusions: Presence of vehicles in the household was associated positively with physical inactivity in transportation, both for men and for women. This should be taken into consideration in drawing up public policies for promoting physical activity.
