Effect of a Self-Efficacy-Based Educational Intervention on Breastfeending in Primigravid Women: A Randomized Controlled Trial (PROMILACT)

12. maj 2026 opdateret af: Guadalupe Aguilar Hernández, Instituto Mexicano del Seguro Social

Effect of a Self-Efficacy-Based Educational Intervention on Exclusive Breastfeeding in Primigravid Women Attending a Primary Care Center: A Randomized Controlled Trial

This randomized controlled trial aims to evaluate the effect of a self-efficacy-based educational intervention on exclusive breastfeeding among primigravid women attending a primary care center in Mexico. Participants in the intervention group will receive four weekly educational sessions focused on breastfeeding knowledge, self-efficacy, problem-solving skills, and emotional support during the third trimester of pregnancy. The control group will receive standard prenatal care. Breastfeeding self-efficacy and exclusive breastfeeding rates will be evaluated during postpartum follow-up at 1 and 3 months after delivery.

Detaljeret beskrivelse

Exclusive breastfeeding is recognized as one of the most effective interventions for improving maternal and infant health outcomes. However, breastfeeding rates remain below international recommendations in many settings, particularly among first-time mothers who may experience uncertainty, lack of confidence, and insufficient support during the prenatal and postpartum periods.

Self-efficacy theory suggests that maternal confidence plays a critical role in breastfeeding initiation and maintenance. Educational interventions based on self-efficacy principles may improve breastfeeding behaviors and increase exclusive breastfeeding duration.

This study is a randomized controlled trial conducted in a primary care setting of the Mexican Social Security Institute (IMSS) in Acapulco, Guerrero, Mexico. The study will include primigravid women in the third trimester of pregnancy receiving prenatal care at Unidad de Medicina Familiar No. 9.

Participants assigned to the intervention group will receive a structured educational intervention consisting of four weekly sessions lasting approximately 90 minutes each. The sessions will address breastfeeding physiology, breastfeeding techniques, common breastfeeding difficulties, emotional support, and strategies to improve maternal self-efficacy. The control group will continue receiving standard prenatal care routinely provided by the institution.

The primary outcomes will include breastfeeding self-efficacy and exclusive breastfeeding rates during postpartum follow-up. Secondary outcomes may include breastfeeding knowledge and breastfeeding continuation at different postpartum time points.

Breastfeeding self-efficacy will be evaluated using the Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF). Follow-up evaluations will be performed at 1 and 3 months postpartum.
