摘要

Purpose Increased physical activity maintains functional fitness and prevents aging-related declines in muscle mass for older adults. However, physical inactivity is prevalent in aging population, particularly in those living in rural areas. In this study we assessed the effectiveness of a 3-month peer support and mobile application-based walking programme on physical activity and physical function in rural older Chinese adults. Methods This was a cluster randomized control trial recruiting adults aged >= 60 years. Participants were randomized into intervention and control groups (4 clusters with 36 participants for each group). The intervention included face-to-face physical activity group sessions, peer-led walking, and mobile application-based feedback. Primary outcome was pedometer-measured daily walking steps, and secondary outcomes mainly included physical function and body composition. Both intention-to-treat and per-protocol analyses were performed. Results Of the included 72 participants (mean age 66.9 years, male 36.1%), 64 completed the study. Intention-to-treat analysis showed that after 3-month walking programme, physical activity was increased by 408 steps/day and grip strength by 1.25 kg in the intervention group compared with the control group. However, no significant outcomes were observed on gait speed, chair-rising time, or body composition. Per-protocol analysis showed similar results. Linear regression analyses showed that changes in daily steps were associated with changes in gait speed (ss = 0.63, P < 0.001) and chair-rising time (ss = - 0.31, P = 0.01). Conclusions The 3-month peer support and mobile application-based walking programme could improve physical activity and physical function in rural older adults. Key summary pointsAim To assess the effectiveness of a 3-month peer support and mobile application-based walking programme on physical activity and physical function in rural older Chinese adults. Findings (1) Peer support and mobile application-based walking programme increased physical activity and grip strength but not gait speed, chair-rising time, or body composition in rural older Chinese adults. (2) Increases in daily steps were associated with gains in gait speed and decreases in chair-rising time. Message Peer support and mobile application-based walking programme improved physical activity and physical function in rural older adults.
