Objective: Family-based interventions represent a potentially valuable route to increasing child physical activity (PA) in children. A dual meta-analysis and realist synthesis approach examined existing interventions to assist those developing programmes to encourage uptake and maintenance of PA in children. Design: Studies were screened for inclusion based on including participants aged 5-12y, having a substantive aim of increasing PA by engaging the family, and reporting on PA outcome. Duplicate data extraction and quality assessment was conducted. Meta-analysis was conducted in STATA. Realist synthesis included theory development and evidence mapping. Results: Forty-seven studies were included, of which three received a ‘strong’ quality rating, 21 ‘moderate’, and 23 ‘weak’. The meta-analysis (19 studies) demonstrated a significant small effect in favour of the experimental group (standardised mean difference: 0.41; 95%CI 0.15-0.67). Sensitivity analysis, removing one outlier, reduced this to 0.29 (95%CI 0.14-0.45). Realist synthesis (28 studies) provided insight into intervention context (particularly, family constraints, ethnicity and parental motivation), and strategies to change PA (notably, goal-setting and reinforcement combined). Conclusion: This review provides key recommendations to inform policy makers and other practitioners in developing evidence-based interventions aimed at engaging the family to increase PA in children, and identifies avenues for future research.
