Breastfeeding is vital to a child's lifelong health and has significant positive benefits to mother's health. World Health Organization recommends beginning exclusively breastfeeding within the first hour after birth and continuing during the first 6 months of infant's life. The purpose of this review is to identify and examine breastfeeding interventions conducted across the Spanish-speaking countries. A scoping review of the literature was conducted across 14 databases for relevant publications published through April 2023 to find studies in Spanish-speaking countries that involved breastfeeding as an intervention component. A total of 46 peer-reviewed articles were included in this review, across 12 Spanish-speaking countries. Participants ranged from pregnant women, mothers, mother-infant pair, and health care professionals. Intervention at the individual level in combination with support from trained health care professionals or peer counselors seemed to have higher improvements in breastfeeding rates. The greatest improvement in exclusively breastfeeding for 6 months was seen in interventions that included prenatal and postnatal intensive lactation education, for a period of 12 months. The most effective interventions that improved rates of any breastfeeding included promotional activities, educations workshop, and training of health care staff along with changes in hospital care. Breastfeeding promotion is an economical and effective intervention to increase breastfeeding behavior and thereby improving breastfeeding adherence across Spanish-speaking countries.
