Towards Universal Screening for Postpartum Depression in China: Lessons Learned from a Comprehensive Prevention Programme in Shenzhen.

This study demonstrated high efficacy of Shenzhen's comprehensive PPD prevention programme initiated in 2013. The resultant rise in the screening rate among all postpartum women, together with a high referral rate of those screened positive, have contributed to the city's relatively low PPD prevalence. PPD screening and intervention should be included as part of basic public health services to ensure universal coverage and specific strategies should be adopted to ensure referral uptake.
