缺乏可比性一直是体力活动研究的一个主要限制，原因是使用了不同的方法学工具和不一致的截止点。这项研究旨在比较巴西两个地区成年人的体力活动水平：(A)巴西最富有的州圣保罗；(B)巴西南部中等城市佩洛塔斯。这两个站点都使用了基于人口的横断面设计，采用了多阶段抽样策略。采用简式国际体力活动问卷对体力活动水平进行评估。佩洛塔斯的久坐生活方式的流行率是圣保罗的三倍。另一方面，非常活跃的受试者在佩洛塔斯的比例明显更高。运动不足的个体(久坐+不规律运动)的比例在两个地点之间几乎相同。社会经济地位与两个地点的体力活动水平呈负相关。在不够活跃的受试者中，那些住在圣保罗的人至少从事的活动量有限。另一方面，在足够活跃的人中，住在佩洛塔斯的人更活跃。
Lack of comparability has been a major limitation in studies on physical activity, due to the utilization of different methodological instruments and inconsistent cut-off points. This study aims to compare the levels of physical activity in adults from two Brazilian areas: (a) Sao Paulo, the richest State in the country; (b) Pelotas, a medium-sized southern Brazilian city. Both sites used cross-sectional population-based designs, with multiple-stage sampling strategies. Level of physical activity was assessed with the short version of the International Physical Activity Questionnaire. Prevalence of sedentary lifestyle was three times higher in Pelotas than in Sao Paulo. On the other hand, the proportion of very active subjects was significantly higher in Pelotas. The proportion of insufficiently active individuals (sedentary + irregularly active) was almost identical between the sites. Socioeconomic status was inversely related to level of physical activity in both sites. Among the insufficiently active subjects, those living in Sao Paulo are at least engaged in a limited amount of activity. On the other hand, among sufficiently active people, those living in Pelotas are more active.
