Purpose: The objective of this integrative review is to evaluate the effectiveness of breastfeeding education. Methods: This integrative review has been composed of the period between January 2000 and February 2015 using the keywords “breastfeeding education, prenatal, and postnatal.” After searching through these results, a total of 33 full lengths randomized controlled, cohort, semi-experimental papers in English and Turkish focusing on providing breastfeeding education for the mothers, prenatal and postnatal periods have been chosen for evaluation. Results: According to results of the review, to promote breastfeeding, prenatal and postnatal breastfeeding education have been conducted. A significant amount of trials about breastfeeding education contains various methods of breastfeeding in this review. The most prominent methods observed in the trials are phone calls, videos/slides, home visits, brochures/written documents/books, individual support/education, and peer counseling/support. Initiation of breastfeeding, breastfeeding duration, exclusive breastfeeding, breastfeeding rate, and knowledge level are the variants that were concentrated on the trials. It is observed that in the trials breastfeeding duration, exclusive breastfeeding, and breastfeeding rate levels are the most positive affected variants by education and support. Some interventions were also effective on breastfeeding attitude, satisfaction, and self-efficacy in some studies. Conclusions: It is of outmost importance that mothers should be educated and counseled by nurses and midwives about initiating breastfeeding, exclusive breastfeeding and effective continuation of it. Other factors which affect breastfeeding beside education should be determined, and appropriate interventions should be applied.
