Abstract
OBJECTIVE: Physical activity interventions have been shown to improve the health of people with schizophrenia, yet treatment dropout poses an important challenge in this population, and rates vary substantially across studies. We conducted a meta-analysis to investigate the prevalence and predictors of treatment dropout in physical activity interventions in people with schizophrenia.
METHOD: We systematically searched major electronic databases from inception until August 2015. Randomized controlled trials of physical activity interventions in people with schizophrenia reporting dropout rates were included. Two independent authors conducted searches and extracted data. Random-effects meta-analysis and meta-regression analyses were conducted.
RESULTS: In 19 studies, 594 patients with schizophrenia assigned to exercise interventions were investigated (age=37.2 years, 67.5% male, range=37.5%-100%). Trim and fill adjusted treatment dropout rate was 26.7% [95% confidence interval (CI)=19.7%-35.0%], which is more than double than in nonactive control interventions (odds ratio=2.15, 95% CI=1.29-3.58, P=.003). In the multivariate regression, qualification of the professional delivering the intervention (β=-1.06, 95% CI=-1.77 to -0.35, P=.003) moderated treatment dropout rates, while continuous supervision of physical activity approached statistical significance (P=.05).
CONCLUSIONS: Qualified professionals (e.g., physical therapists/exercise physiologists) should prescribe supervised physical activity for people with schizophrenia to enhance adherence, improve psychiatric symptoms and reduce the onset and burden of cardiovascular disease.
