Only 2 studies targeted underserved populations.Īlthough we identified a substantial number of randomized controlled trials, most evidence for physical activity interventions for older people in low- and middle-income countries is limited to upper middle-income countries. The outcomes measured more often were intrinsic capacity (59%) and functional ability (51%), whereas physical activity, falls, and social outcomes were rare. The intervention most commonly investigated was structured exercise (63%) and 'no intervention' was the most frequent comparator (47%). Most studies investigated a mixed population in terms of sex (68%), with a mean age between 65 and 70 years (36%), not selected on the basis of having a specific health condition (55%). Studies were mostly conducted in upper middle-income countries (89%), often assessing physical activity interventions through randomized controlled trials (82%). We included 234 studies from 19 countries, investigating 259 distinct physical activity interventions. Data were summarized using descriptive statistics. A second reviewer double-checked the data extraction of a randomly selected sample of interventions (20%).

Following study selection, one reviewer extracted relevant data. We searched 9 electronic databases to identify randomized controlled trials or quasi-randomized trials studies investigating physical activity interventions for people aged 60+ in low- and middle-income countries. This review examined physical activity interventions for older people from low- and middle-income countries. Most reviews investigating physical activity interventions for older people consider evidence primarily from high-income countries.
