Urban collective garden participation and health: a systematic literature review of potential benefits for free-living adults

Urban Farm DB summary

A systematic review searching January 2000 to August 2020 for quantitative studies on urban collective gardening and health among free-living adults in high-income countries; 15 of 1,261 identified articles met the criteria. Gardeners reported higher fruit and vegetable consumption than non-gardeners and most studies found positive associations with mental and social health, while results for physical activity and physiological measures were mixed. However, 13 of the 15 studies were cross-sectional and subject to selection bias and only 3 used objective measurement, so the authors conclude that longitudinal studies are needed before the suggested health benefits can be regarded as confirmed.
