Background: We have previously reported improved caregiver mental health and infant behavior at 2 years following a home-based preventive care program for very preterm infants and their caregivers. This study aimed to determine the longer-term effectiveness of the program by reviewing caregivers and children at preschool age.
Methods: One hundred twenty very preterm infants (<30 weeks' gestation) were randomly allocated to intervention (n = 61) or control (n = 59) groups.
