Abstract
Background & aim: Many new mothers discontinue breastfeeding prematurely. Exclusive Breastfeeding (EBF) during the first six months of life is widely recognized as an optimal feeding practice that supports infant health and survival. This study examined the effect of a 30-minute oxytocin massage on breast milk volume and infant weight gain among early postpartum women.
Methods: A randomized single-blind controlled trial with a two-group pretest–posttest design was conducted among 60 postpartum women. Participants were randomly assigned to two groups using computer-generated randomization applying allocation concealment. The intervention group received a 30-minute oxytocin massage, while the control group received a 15-minute oxytocin massage for three consecutive days. Breast milk volume was measured using standardized manual milk expression, and infant weight was assessed using calibrated infant weighing scales. Outcomes were evaluated at baseline and after completion of the intervention. Data were analyzed using SPSS V. 20 with paired- and independent-samples t-tests.
Results: The mean age of participants was 28.3 ± 5.1 years. The increase in breast milk volume and infant weight was greater in the intervention group (mean = 10.03 mL and 151.50 g) than the control group (mean = 8.33 mL and 106.16 g). These differences were statistically significant for both breast milk volume (P< 0.001) and infant weight gain (P< 0.001). ANCOVA also showed significant between-group differences.
Conclusion: A 30-minute oxytocin massage may improve breast milk volume and infant weight gain, offering a practical, low-cost method for postpartum lactation support.
