Evidence Summary for Breastfeeding in Postpartum Women with Hypertensive Disorders of Pregnancy

To systematically retrieve, extract, and synthesize the best available evidence on breastfeeding in the postpartum period for women with hypertensive disorders of pregnancy (HDP), and to provide an evidence-based foundation for clinical decision-making and interventions regarding postpartum breastfeeding in HDP patients. Based on the “6S” evidence model, a systematic search was conducted across domestic and international computerized decision support systems, guideline websites, databases, and professional association websites for evidence related to postpartum breastfeeding in HDP patients, including guidelines, evidence summaries, clinical decisions, expert consensus, and systematic reviews. The search period spanned from the inception of the databases to March 2025. A total of 12 articles were included, comprising 5 guidelines, 1 meta-analysis, 1 evidence summary, 3 randomized controlled trials, and 2 quasi-experimental studies. Through discussion among the two researchers, 19 relevant pieces of evidence were synthesized across six aspects: breastfeeding practices, recommendations for postpartum medication use, postpartum follow-up and screening, labor and delivery care, lifestyle interventions, and postpartum monitoring. This study provides a comprehensive summary of the best available evidence on postpartum breastfeeding for HDP patients, offering an evidence-based foundation for targeted clinical application.
