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

Aim: We determined the prevalence and predictors of formula supplementation for healthy, term newborn infants in hospital.

Methods: 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.

Results: 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.

Conclusion: An unacceptably high proportion of healthy newborn infants received formula in hospital.
