The aim of this study was to ascertain the prevalence of physical inactivity and examine the role of potential predictors in a very low-income adult population in a slum located in Recife city, northeast of Brazil. A cross-sectional study was conducted with 1,176 subjects aged 20-60 years residing in a slum. Using the short version of the International Physical Activity Questionnaire, 307 (26.1%) study participants-97 (23.8%) men and 210 (27.3%) women-have a low physical activity score (MET-minutes per week). Increased age was associated with physical inactivity only in people without overweight/obesity. Low physical activity was less common (i.e., respondents were more active) than in other Brazilian population-based studies. These results suggest that the relationship between physical activity and socioeconomic level is more complex and depends on the internal characteristics of the community.
本研究旨在确定极度贫困成年人中体力活动不足的流行率，并探讨潜在预测因素在其中的作用，研究对象为巴西东北部累西腓市一个贫民窟的 1176 名 20-60 岁居民。采用国际体力活动问卷短版进行横断面研究，307 名（26.1%）研究参与者-97 名（23.8%）男性和 210 名（27.3%）女性-体力活动得分较低（MET-分钟/周）。仅在无超重/肥胖的人群中，年龄增长与体力活动不足相关。与其他基于巴西人群的研究相比，体力活动不足的情况（即，受访者更活跃）较少见。这些结果表明，体力活动与社会经济水平之间的关系更为复杂，并且取决于社区的内在特征。
