Aim: To evaluate children born post-term (gestational age ≥ 42 weeks) with respect to developmental data obtained at the ages of 4 and 5.5 y. Methods: The study population included all children (n = 354) born in 1991 at Huddinge University Hospital with a gestational age of ≥ 42 wk. The births were identified and perinatal data were collected through the Swedish National Birth Registry. Developmental assessments from the child health centres were analysed. Children born at term, but before a gestational age of 42 wk, served as controls. Logistic regression analysis was used to analyse the data. Results: Children born post-term had more developmental deviations than the controls (estimated odds ratio 2.20; 95% CI: 1.29-3.85) . Boys had more deviations than girls (estimated odds ratio 1.92; 95% CI: 1.11-3.45). Conclusion: Our results indicate that there might be an association between post-term birth and developmental deviations.
