Abstract

Background: There is increasing interest in the association between nature, health and wellbeing. However, the populations studied are generally very heterogeneous, including both healthy patients and patients with various psychiatric disorders and/or carried out in nursing homes or hospitals. More research is needed to determine the effectiveness of nature-based interventions in the treatment of depressive disorders on an outpatient basis. Aim: Summerise systematically the effectiveness of nature-based intervention for increasing wellbeing and reducing symptoms of depression in the adult population living in the community and being diagnosed with depression. Methods : We conducted an overview of systematic reviews (SRs) and meta-analysis to provide the most comprehensive summary of the effect of nature-based interventions on depression. We started by looking up on PROSPERO trials that could be ongoing and relative to the subject. Then we ran the search in several database (Pubmed, Embase, Cochrane and Psychinfo). We did a hand search through the references to decrease the risk of missing potential reviews. The reviews were assessed for quality using the AMSTAR tool for critical appraisal and the ROBIS tool to assess the risk of bias. We extracted the data relating to depressive patient from each review. Studies that included adults (aged ≥18 years) in community-based settings with depression were eligible for inclusion. Eligible interventions were structured outdoor activities in green and/or blue space for mental health. Results: 11 systematic reviews and meta-analysis met inclusion criteria. 15 primary studies were extracted. 587 participants diagnosed with depression were included in different nature based interventions. We divided them between walking in nature, horticultural therapy (gardening) and forest bathing. Research limitations/implications: Heterogeneity and small sample sizes limited the results. Poor reporting precluded meta-analysis in some studies. Initial findings for wellbeing and depression are promising and should be corroborated in future studies. The research area is active, and the results of the ongoing trials identified will add to the evidence base.
