Is School Gardening Combined with Physical Activity Intervention Effective for Improving Childhood Obesity? A Systematic Review and Meta-Analysis

Urban Farm DB summary

A meta-analysis pooling 14 randomised controlled trials covering 9,187 children aged 7–12 that tested school gardening combined with physical activity. Fruit and vegetable intake increased significantly, but the intervention showed no clear effect on BMI and related obesity measures, with only a modest positive direction for weight reduction. The result separates dietary behaviour change from anthropometric change and shows that whether school gardens are judged effective against obesity depends heavily on which outcome is measured.
