Purpose Of Review:
Community-based interventions (CBIs) are widely used to address behavioral risk factors for non-communicable diseases, yet evidence of their effectiveness in low- and middle-income countries (LMICs) remains limited. This study systematically reviewed evidence on the effectiveness of CBIs promoting physical activity (PA) and/or reducing sedentary behavior (SB) among community-dwelling adults in LMICs. We searched PubMed, Embase, Scopus, and the Cochrane Library (2000-2024) for CBIs in LMICs. Primary outcomes were changes in PA and/or SB. Descriptive and graphical depictions were used to draw inferences.
Recent Findings:
We selected 24 studies (11 RCTs) from 15,396 for review. Most studies (n = 16) reported significant improvements in PA outcomes. Changes were observed in Metabolic Equivalents (+ 100 - +2,700), moderate-to-vigorous PA (+ 7 to + 60 min/week), and steps/day (+ 3,000). Broadly, interventions were delivered using digital/technology format (n = 10), peer-led/community health worker-facilitated (n = 8), and Environmental restructuring (n = 6), with the digital interventions depicting the most consistent significant improvements. Two studies directly measured SB as a primary outcome. Short- (≤ 6 months; n = 11) and medium-duration (6-12 months; n = 4) interventions more frequently reported significant PA improvements than long-duration interventions (> 12 months; n = 9). PA/SB-focused CBI demonstrated proportions of significant effects similar to those of broader lifestyle interventions (88.9% and 53.3%, respectively). CBIs can be effective in improving PA in LMICs, although evidence is heterogeneous and SB is less addressed. Digital interventions show more consistent positive signals, but high heterogeneity in studies precludes firm conclusions. The impact of duration on effectiveness looks counterintuitive but underscores the need for more rigorous evaluation of longer-duration interventions and SB outcomes.
