Enhancing breastfeeding outcomes in postpartum women with insufficient breast milk supply: protocol for a six-month longitudinal randomized trial of self-administered acupressure
摘要
Insufficient breast milk supply (IBMS) is a critical challenge to achieving optimal breastfeeding outcomes worldwide. While Traditional Chinese Medicine (TCM)-based acupressure has demonstrated promise for lactation, its clinical effectiveness remains insufficiently explored. This study aims to investigate the effectiveness of self-administered acupressure (SAA) as a non-pharmacological intervention for IBMS and its longitudinal effects on breastfeeding outcomes.
MethodsThis six-month randomized controlled trial (RCT) will enroll 184 postpartum women experiencing IBMS from the Department of Obstetrics at West China Second University Hospital. Participants will be randomly assigned to either an intervention group receiving daily SAA targeting three acupoints (Danzhong, Rugen, and Shaoze) performed 3 times per day for 10–15 min each session, or a control group receiving routine postpartum care. The primary outcome is the exclusive breastfeeding rate. Secondary outcomes include mother-infant attachment, postpartum depression, breastfeeding self-efficacy, infant feeding attitude, and maternal parenting confidence. Outcome assessments will be conducted at hospital discharge, and at 14 days, 42 days, 3 months, and 6 months postpartum. In addition, breast milk samples will be collected from 30 participants in each group at 14 days postpartum to analyze lactation-related hormonal biomarkers.
DiscussionThis trial will provide high-quality evidence on the clinical utility of SAA in managing IBMS and enhancing breastfeeding outcomes over time. By integrating psychosocial assessments with hormonal analysis, the study aims to inform the development of safe, accessible, and culturally appropriate lactation support strategies, particularly in low-resource settings. Findings may contribute to the advancement of personalized, non-invasive interventions to support sustained breastfeeding.
