Effect of physical activity intervention on weight change in rural older Chinese: a cluster randomized controlled trial

Physical activity intervention resulted in weight loss in rural older sample at 24 months. This suggested that physical activity interventions are feasible for weight loss among older adults, especially for those with overweight/obesity or aged under 80.
