Abstract

Abstract: The introduction of fluids other than breast milk during the first few days of life or later neonatal period has been identified as a risk factor for suboptimal breastfeeding (BF) outcomes in numerous studies using varying study designs. However, the relationship between early introduction of fluids other than breast milk and BF outcomes has not been systematically assessed using only prospective studies that can establish temporality, which is critical for determining whether observed associations are causal. We conducted a systematic review and meta‐analysis of prospective studies to assess if there is a difference in BF outcomes as a result of the introduction of: (a) milk‐based prelacteals, (b) water‐based prelacteals and (c) breast milk substitutes (BMS) between 4 days and 4 weeks postpartum. We searched PubMed, Lilacs, Web of Science and other repositories for original research investigating the relationship between early introduction of prelacteals and/or BMS and BF outcomes. Forty‐eight studies met the inclusion criteria for the systematic review. Of the 39 prelacteal feeding studies, 27 had the prerequisite statistical information for inclusion in the meta‐analysis. Findings from the meta‐analysis showed a relationship between prelacteals and exclusive BF cessation (RR 1.44; 1.29–1.60) and any BF cessation (2.23; 1.63–3.06) among infants under 6 months old. Nine studies focusing on the introduction of BMS during the neonatal period identified this practice as a statistically significant risk factor for a shorter BF duration. Effective interventions are needed to prevent the introduction of unnecessary milk‐based prelacteals and BMS during the perinatal and neonatal periods to improve BF outcomes. Key messages: The practice of prelacteal feeding and introduction of breastmilk substitutes (BMS) during the neonatal period is widespread across the globe. In this systematic review and meta‐analysis of prospective studies, the introduction of prelacteals was associated with suboptimal breastfeeding practices including a higher risk of not exclusive breastfeeding and any breastfeeding cessation among infants under 6 months of age. Prospective studies show that the introduction of BMS during the neonatal period is a risk factor for suboptimal breastfeeding practices. Facility and community‐based interventions are needed to prevent the introduction of prelacteals perinatally and BMS during the neonatal period. Abstract : Findings from the meta‐analysis showed a relationship between prelacteals and lack of exclusive breastfeeding and any breastfeeding cessation among infants under 6 months old. Effective interventions are needed to prevent the introduction of unnecessary milk‐based prelacteals during the perinatal and neonatal periods to improve breastfeeding outcomes.
