Predictors of supplementation for breastfed babies in a Baby-Friendly hospital

Supplementation of breastfed babies is common during the hospital stay.

The Baby Friendly Hospital Initiative (BFHI) optimises practices to support exclusive breastfeeding, yet supplementation is still prevalent.

To determine predictors for supplementation in a cohort of breastfed babies in a Baby-Friendly hospital.

Electronic hospital records of 1530 healthy term or near term singleton infants and their mothers were examined retrospectively and analysed to identify factors associated with in-hospital supplementation using Poisson regression (unadjusted and adjusted).

Fifteen percent of breastfed infants were supplemented during their hospital stay. Analysis by multivariable Poisson regression found that supplementation was independently associated with overweight (reference normal weight) (aRR [adjusted relative risk]=1.46; 95% CI: 1.11-1.93); primiparity (aRR=1.40; 95% CI: 1.09-1.80); early term gestation (37-37⁶ weeks, aRR=2.79; 95% CI: 1.88-4.15; 38-38⁶ weeks, aRR=2.03, 95%CI: 1.46-2.82); birthweight less than 2500 grams (reference 3000-3499 grams) (aRR=3.60; 95% CI: 2.32-5.60) and use of postpartum uterotonic (aRR=2.47; 95% CI: 1.09-5.55). Greater than 65 minutes of skin-to-skin contact at birth reduced the risk of supplementation (aRR=0.66; 95% CI; 0.48-0.92).

These identified predictors for supplementation, can inform the development of interventions for mother-infant pairs antenatally or in the early postpartum period around increased breastfeeding education and support to reduce supplementation. It may also be possible to reduce supplementation through judicious use of postpartum uterotonics and facilitation of mother-infant skin-to-skin contact at birth for greater than one hour duration.
