Abstract: Objective： To investigate the related risk factors of postpartum depression， and provide a theoretical basis for community health care. Methods：The retrospective analysis of 324 cases，with the maternal Edinburgh Postnatal Depression Scale（EPDS） and self-designed questionnaire, was done. Results：The occurrence of postpartum depression was 11.42%. The marital relations，family condition and care were important factors of postpartum depression（P＜0.05），while the birth age，mode of delivery and maternal education level may be those relevant factors of postpartum depression（but P＞0.05）. The depressive symptoms were significantly improved in 28 patients with the community intervention therapy（the improved rate，75.7%）. Conclusions：Community health workers can provide prenatal and postnatal care for pregnant women，as well as medical intervention and effective social support， which is important to prevent postpartum depression and reduce its incidence.
