Studies suggest that preterm delivery is a risk factor for early language delays, but knowledge is scarce about the persistence of the delays and whether the association is of a linear kind. To resolve this, effects of confounding risk factors that are both shared within a family and pregnancy specific need to be distinguished from effects of preterm delivery. Our study examines the association between early gestational age and language outcomes, using a sibling-control design.
