Aim: This study estimated the healthcare cost savings for the government due to the prevention of gastroenteritis (GE) infections and lower respiratory tract infections (LRTI) in the first year of life, attributed to an increase in the exclusive breastfeeding rate at 4 months in Hong Kong.
Methods: The model used the best available data inputs, with uncertainty considered using probabilistic sensitivity analysis. We additionally assessed the impact of neonatal jaundice (NNJ) on the economic benefits of increasing exclusive breastfeeding rates.
