Perinatal breastfeeding interventions including fathers/partners: A systematic review of the literature

Objective: Support from fathers is consistently associated with improved breastfeeding duration and exclusivity rates. Additionally, there is growing evidence that fathers want to be included in breastfeeding interventions provided by health care professionals. The objective of this review was to determine the effect of partner-inclusive educational and psychosocial interventions on breastfeeding initiation, duration, and exclusivity.

Design: A systematic review was conducted using a search strategy developed with an expert health sciences librarian. Electronic databases MEDLINE, EMBASE, CINAHL, and PsycINFO were systematically searched for randomized controlled trials and quasi-experimental studies from inception to August 4, 2018. Independent data extraction and quality assessments were conducted by authors using Cochrane Collaboration tools. Due to significant heterogeneity in intervention content, outcome measures, and follow-up time points, data were synthesized qualitatively.

Findings: 3982 articles were identified, of which 12 studies in 15 publications met the inclusion criteria and were included. All of the studies improved at least one breastfeeding outcome, including duration (n = 5/9) and exclusivity (n = 8/10) up to 24 weeks postpartum. Six studies examined increasing paternal breastfeeding support and all found beneficial effects. Biases were identified in the studies with the most common bias relating to the randomization process and the blinding of outcome assessors.

Implications for practice: The inclusion of fathers/partners in breastfeeding interventions improves breastfeeding initiation, duration, and exclusivity rates. Interventions that include face-to-face information delivery, are designed in a culturally appropriate manner, and provide information on how partners can support breastfeeding are more likely to have a beneficial effect. Research is warranted to examine the underlying intervention mechanisms.
