[Evaluation of the effectiveness of home-based physical activity promotion by community health workers].

This study analyzed the effectiveness of physical activity promotion by community health workers (CHW) during home visits. This was a non-randomized controlled trial that lasted six months, with one group of CHW that received training to promote physical activity during home visits among users of the Brazilian Unified National Health System (SUS) and a control group. Physical activity and stages of behavior change were evaluated in 176 adults (n = 90 in the intervention group and n = 86 in the control group) assisted by the CHW. Associations, prevalence ratios, and generalized estimate equations were conducted to verify differences between groups. No evidence of differences in physical activity and stages of behavior change were observed between the two groups. CHW from the intervention group conducted more home visits promoting physical activity among elders, those with low schooling, unemployed, and those with chronic diseases. It is important to reassess the work and priorities of CHW to expand physical activity promotion under the SUS.
