Objective: The objective of the systematic review will be to evaluate the effect of paternity leave or fathers' parental leave on infant mortality rate, hospitalization, vaccination compliance, and breastfeeding duration.
Introduction: Current studies indicate that paternity leave positively affects infant health, but there is a significant lack of synthesized research on its impact on key infant health indicators. A systematic review of the existing evidence will help identify best practices and guide further research and policy development in this area.
