[Prevalence of physical inactivity in adult women in São Leopoldo, Rio Grande do Sul, Brazil].

The aim of this study was to evaluate the prevalence of physical inactivity and associated factors in adult women (20-60 years) in São Leopoldo, Rio Grande do Sul, Brazil. A cross-sectional population-based study was carried out in 40 census tracts of the city. Physical inactivity was defined as no leisure-time physical activity or light-intensity activities no more than once a week. Of the 1,026 women interviewed, 380 (37.0%; 95%CI: 34.0-40.0) were classified as inactive. Another 609 (59.3%) reported moderate or vigorous activities less than three times a week. In the crude analysis, physical inactivity was higher among non-white women, those with higher parity, with less schooling, low income, and obese. After adjustment, only the effect of body mass index remained statistically significant. Local and national policies for counseling and environmental improvements are necessary to reverse the high prevalence of physical inactivity observed in the community.
