Effectiveness of Horticultural Therapy in Aged People with Depression: A Systematic Review and Meta-Analysis
Summary
The study synthesizes findings from 13 studies involving 698 older adults with depression to assess the impact of horticultural therapy. The meta-analysis confirms significant reductions in depressive symptoms, with care-providing settings (e.g., nursing homes, hospitals) yielding better outcomes than community-based programs. Participatory activities such as planting and harvesting were more effective than observational activities like walking in gardens. Additionally, interventions lasting 4–8 weeks showed the most significant improvements, whereas longer programs had diminished effects.
Key takeaways highlight horticultural therapy as a non-pharmacological intervention that enhances mood, social engagement, and cognitive function. The study suggests designing therapy programs in structured care settings with hands-on activities for at least 4–8 weeks to maximize benefits. Future research should explore the long-term impacts and mechanisms behind horticultural therapy’s effectiveness in treating geriatric depression.
