Croatian mothers were 11 times more likely to give their newborn infants formula in hospital if they had used it for their older children.

Abstract

We determined the prevalence and predictors of formula supplementation for healthy, term newborn infants in hospital. A cross-sectional study was conducted from 1 June to 21 October 2020 among Croatian women who gave birth to healthy newborn infants of ≥37 weeks gestation and birth weight of ≥2500 g at the University Hospital of Split, Croatia. The mothers completed a questionnaire on hospital infant feeding practices and breastfeeding self-efficacy. Multinomial logistic regression investigated associations between perinatal factors and formula supplementation. We approached 392 mothers, and 355 (90.6%) were included: 286 (80.6%) said their newborn infant received formula in hospital and it was at their request in 173/286 (60.5%) of cases. The adjusted analyses identified factors associated with increased odd ratios (OR) and 95% confidence intervals (CI) for formula supplementation: no previous breastfeeding experience (OR 9.42, 95% CI 3.51-25.28), breastfeeding difficulties in hospital (OR 9.12, 95% CI 3.46-24.09) and older children who received formula during their birth hospitalisation (OR 11.51, 95% CI 4.4-30.1). Mothers were not routinely notified of the risks. An unacceptably high proportion of healthy newborn infants received formula in hospital.
