Abstract:Abstract: OBJECTIVE To investigate the prevalence and influencing factors of postpartum depression among puerperant in a community in Guangzhou,aiming toidentify high-risk individuals early and provide timely mental health guidance and intervention. METHODS Data were collected via questionnaire surveys from 284 puerperant who gave birth between July 2023 and January 2025, resided in the community of Guangzhou,and had established records in the Guangzhou Maternal and Child Health Information System. Statistical analysis was performed on the collected data.RESULTS The detection rate of postpartum depression among 284 puerperant in this community was 17.61%.Univariate analysis revealed statistically significant associations between maternal age,living environment, presence of pregnancy complications,lactation volume,infant neonatal diseases,infant feeding practices,postpartum sleep quality, and perceived stress levels with postpartum depression detection rate(x²=4.569,55.843,4.781,19.624,6.342,74.137,66.944, 134.360;P<0.05).Multivariate analysis identified mixed feeding,unsatisfied living environment,and poor postpartum sleep as risk factors for postpartum depression,while perceived stress levels between 0-13 points served as a protective factor.CONCLUSION The incidence of postpartum depression among puerperant in a Guangzhou community is at a moderate level.This suggests that psychological assessment and diagnosis should be conducted early for those with risk factors for postpartum depression,accompanied by mental health education and effective interventions to reduce the incidence of postpartum depression of puerperant.
