RESUMEN
BACKGROUND: The World Health Organization recommends exclusive breastfeeding for 6 months followed by continued breastfeeding with complementary food up to 2 years of age or beyond. This study aimed to investigate the effect of mobile -based education on the self-efficacy of lactating women in the postpartum period. METHODS: A quasi-experimental study was carried out in 2018 in Shirvan, Iran among 69 postpartum women. Participants were assigned to intervention (n = 33) and control (n = 36) groups on the first day after delivery by random allocation. Intervention group received the mobile-based training for 4 weeks in the form of text messages, photos, video clips, and audio files. The control group received routine hospital care and training. Data were collected on demographic characteristics, delivery information, and the breastfeeding self-efficacy. Self-efficacy was measured in two groups at three time points; the first day after delivery, 4 weeks after delivery and 8 weeks after delivery. FINDINGS: The mean and standard deviation of breastfeeding self-efficacy score was higher in the intervention than control group 4 weeks (155.30 ± 10.93 vs 132.52 ± 19.70, P < 0.001) and 8 weeks after delivery (160.18 ± 11.33 vs 132.30 ± 24.09, P < 0.001). Compared to the control group, the rate of exclusive breastfeeding in the intervention group was significantly higher 4 and 8 weeks after the delivery (Pall < 0.05). DISCUSSION: The findings from this study showed a substantial increase in breastfeeding self-efficacy and exclusive breastfeeding in the group who received training through mobile-based education compared to the group that received routine care. APPLICATION TO PRACTICE: Mobile-based breastfeeding education might be a promising strategy to increase breastfeeding self-efficacy. It is suggested that midwives include the design of mobile-based educational programs as part of their educational strategies and use the advantages of this educational method during pregnancy and after childbirth.
