ABSTRACT
Background: Introduction: Physical activity is essential in preventing and treating age-related chronic diseases and mortality. Retirement is a key period to promote health behaviours, as individuals restructure their routines. Thus, we aimed to identify effective components and behaviour change techniques (BCTs) in interventions promoting physical activity in retirement-age individuals. Methods: We conducted a meta-analysis. Included studies were randomised controlled trials that (p)targeted retirement-age adults (50-70 years), (i)applied BCTs, (c)had any comparator, and (o)promoted physical activity. Screening, full-text review, and data extraction were conducted independently by at least two reviewers. A multilevel random effects model with three effect sizes was fitted, and meta-regressions tested several moderators. Results: 67 studies (N = 12,147) were included. High risk of bias related to larger effects, so these studies were excluded from the main analyses. While individual effects were often non-significant, the overall pooled effect was small but statistically significant. Predictors varied across effect sizes and included action planning, motivational interviewing, and prompts/cues. Email and website delivery were associated with smaller effect sizes. Conclusions: The effectiveness of lifestyle interventions is heterogeneous and presented small effects; implementing action planning, motivational interviewing, and prompts could improve the effectiveness. However, many BCTs that are not frequently used remain unexplored.
