Description
Summary:An increasing number of studies have examined the effects of green prescription on various health outcomes. The aim of this study was to systematically review published randomized controlled trial studies on the health benefits of green prescriptions. We searched PubMed, Scopus, and Web of Science for the relevant original articles published in English until June 30, 2023. Our search initially retrieved 26176 articles, of which 31 studies were included in our review after removing the duplicates and excluding ineligible articles based on their titles, abstracts, and full-text review. Consistent positive health benefits of green prescription were reported for psychological health and wellbeing (16 out of 24 studies), cardiometabolic health (five out of nine studies), physical activity (eight out of nine studies), and inflammation (two out of two studies). The reviewed studies did not report any significant benefits in orthopedic conditions, pain, and recovery from exhaustion disorder due to their implemented green prescriptions; however, the number of studies was too small to generalize the effect of green prescriptions on these outcomes. The quality of these studies was generally acceptable, with 28 studies having some concerns regarding their overall risk of bias and only three studies with a high risk of bias. All in all, this systematic review suggests that green prescriptions can be effective in improving various health outcomes, but further studies with larger sample sizes and objective measures are needed.
