Do publicly funded community physical activity programs for middle-aged and older adults in Ireland work?

To strengthen practice-based evidence, pragmatic, yet rigorous, evaluation of real-world programs is necessary. This study sought to add to the evidence for the effectiveness of physical activity programs for middle-aged and older adults offered by publicly funded local sports partnerships (LSPs) in Ireland. We analysed data from 468 individuals aged 50 + years, who took part in the Move for Life cluster randomised feasibility trial. Outcomes were accelerometer-based moderate-to-vigorous intensity physical activity (MVPA), light intensity physical activity (LiPA), standing time, and sedentary time; self-reported compliance with physical activity guidelines, body composition, physical function, and mental well-being. LSP programs included Women on Wheels/Bike for Life, Go for Life Games, Get Ireland Walking, and Men on the Move. We used a difference-in-differences approach to estimate program effects. We found evidence of positive program effects on accelerometer-derived MVPA (Women on Wheels/Bike for Life, Get Ireland Walking), LiPA (Go for Life Games), and sedentary time (Women on Wheels/Bike for Life, Go for Life Games) (p < .05), plus evidence of positive effects on self-reported physical activity for all LSP programs (p < .05). We did not find evidence of program effects on body composition. Outcomes related to physical function were mixed. Men on the Move was the only program where mental well-being scores increased significantly relative to the control group. Despite sample size limitations, the results support the effectiveness of LSP programs over a 6-month period, notably in terms of energy expenditure outcomes, while identifying areas for improvement regarding outcomes related to body composition, physical function and, particularly, mental well-being.
