RESUMO
Physical activity is associated with better global functioning in the general population and in people with physical conditions. However, there is no meta-analytic evidence on the associations between daily physical activity levels and global functioning in people with mental disorders. The objective of the present meta-analysis therefore was to evaluate the associations between daily physical activity levels and global functioning in individuals with mental disorders. Pubmed, Embase, PsycINFO and SPORTdiscus were searched from inception to August 1st, 2022. Risk of bias was assessed using the National Institutes of Health Study Quality Assessment Tools. A random-effects meta-analysis was performed. Ten studies were identified and six were meta-analyzed including 251 adults (39.2 ± 11.9 years, 33.6% of women). The pooled results from six studies found a moderate positive correlation (r = 0.39, 95% CI 0.242 to 0.528, p<0.001, I²=49.3%) between daily physical activity and global functioning. Three out of four studies not included in the meta-analysis also found significant associations between physical activity and global functioning. The current meta-analysis demonstrated a moderate association between daily physical activity and global functioning in individuals with mental disorders. However, the evidence is based on cross-sectional studies and a causal relationship cannot be established. High-quality longitudinal studies aiming to address this relationship should be conducted.
