The Gardening Activities to Reduce Postpartum Stress in Japanese Postpartum Women: Preliminary Evidence from Pilot Single-Arm Trial Study

Objective: There is a need for safer and more effective programs to address postpartum women's mental health dysfunction. The objective of this study was to clarify the effects on mental health, including postpartum depression, by implementing Japanese postpartum women with gardening activities by a pilot single-arm trial. Results 15 women about a year after giving birth, recruited through newspaper advertisements, took part in this pilot study. I used the Japanese version of Edinburgh Postpartum Depression Scale (EPDS) score as the primary outcome measure. Secondary outcome measures were parenting stress, anxiety, and quality of life (QOL). Data collected at pre and post-test were analyzed using a paired t test. The EPDS, stress regarding parents, State-Trait Anxiety Inventory (STAI)-state, and STAI-trait of post-test were significant decreased than pre-test (p < 0.05). Also, physical health and psychological health of the World Health Organization Quality of life 26 (WHOQOL-26) of post-test were significantly increased than pre-test (p < 0.05). The gardening activity might be promising for mitigating depressive mood in postpartum women.
