Background: Since the early 90s a striking rise in deformational plagiocephaly (DP) has been reported, and a causal link between the "back to sleep" position recommended to reduce the risk of sudden infant death syndrome. Recent data suggested that supine position is a risk factor only when combined with other environmental factors
Objective: To evaluate the impact of early intervention in the newborn environment on the prevalence of DP at 4 months of life.
Methods: A multicentric, prospective, controlled study in healthy term neonates.
