RESUMEN
BACKGROUND: The postpartum period is critical for maternal health status after childbirth. The traditional Chinese postpartum confinement practice, "doing-the-month", is considered especially effective in helping mothers recover during the postpartum period. However, research has not provided evidence to confirm its benefits. Postpartum depression is a common postpartum disease that seriously threatens maternal health. The systematic review aims to explore the association between "doing-the-month" and postpartum depression in the Chinese female population and to provide a scientific foundation for evidence-based postpartum maternal care. METHODS: Five databases (PubMed, Embase, Web of Science, Scopus, Cochrane, PsycINFO, and Web of Science) were searched according to the protocol (INPALSY202320102). The JBI assessment tool was used to assess the quality of the included studies. RESULTS: Sixteen quantitative studies from China and Chinese female immigrants in other countries, including 15 cross-sectional studies and 1 randomized controlled study, were identified. Four studies indicated that "doing-the-month" rituals reduced postpartum depression risk while 2 studies showed opposite results; 10 studies did not show a significant association between "doing-the-month" practices and postpartum depression. CONCLUSION: There is conflicting evidence regarding the association between "doing-the-month" and the likelihood of developing postpartum depression. Some studies have explored the impact of family ties, particular rituals, and specific stressors during the postpartum period on the occurrence of postpartum depression in Chinese women. According to current research, "doing-the-month" practice failed to show a significant protective effect on postpartum depression in the Chinese maternal population. Evidence-based medical health education for the Chinese postpartum female community is urgently needed.
