Objective To examine associations between the duration of gestation and health and development outcomes at 2.5 years and 5.5 years using a Japanese population-based longitudinal survey (n = 47â€̂015).

We conducted logistic regression analyses controlling for a set of neonatal and family factors. We also estimated population-attributable fractions.
