Interventions to Increase Physical Activity Among Older Adults: A Meta-Analysis.

ABSTRACT:

Purpose of the study

To determine the overall effectiveness of interventions designed to increase physical activity (PA) behavior among community-dwelling older adults.

Design and methods

Comprehensive literature searching identified eligible PA intervention studies among community-dwelling adults aged 65 and older, or sample mean age of 70. Diverse study characteristics were extracted and outcome data were duplicate coded. Overall mean effect sizes (ESs) were synthesized using a random-effects model. Heterogeneity of effects was analyzed using Q and I(2) statistics. Moderator analyses were conducted using meta-analytic analogues of ANOVA and regression for dichotomous and continuous moderators, respectively.

Results

ESs were calculated from 13,829 primary study subje
