Study design: This study included 1902 very preterm singletons who were transferred to neonatal intensive care units in 9 French regions. We used logistic regression models to compare the risk of cerebral injury associated with maternal hypertension, SGA, and all other causes of preterm delivery. Results: We found that the risk of c-PVL and grade Ⅲ Ⅳ H was higher in infants born after preterm premature rupture of membranes (PPROM) with short latency or idiopathic preterm labor than in infants born to hypertensive mothers. We show that SGA and antepartum maternal hemorrhage significantly increase the risk of IPH. Conclusion: Our results show that infants born to hypertensive mothers have a lower risk of cerebral injuries than infants born following idiopathic preterm labor and PPROM because they are less exposed to prenatal infection.展开更多

METHODS: The data were from the Epipage study, which included all very preterm children (< 33 weeks) born in 1997 in 9 regions of France. The analysis included 1,954 children for whom a medical questionnaire was completed at the age of 2 years (83%of the surviving children). The risk f actors studied were pregnancy complications and specific factors in twins (type of placenta and death of cotwin). Logistic regression analysis was carried out f or singletons and generalized estimating equation models used for twins. RESULTS : The proportion of cerebral palsy was 8%in singletons and 9%in twins. For sin gletons, spontaneous preterm labor (adjusted odds ratio [OR] 3.4, 95%confidence interval [CI] 1.7-6.7), preterm premature rupture of membranes (PPROM) with sh ort latency (adjusted OR 4.9, 95%CI 2.0-11.8), and prolonged PPROM (adjusted OR 2.7, 95%CI 1.4-5.3) were associated with a higher risk of cerebral palsy than was hypertension. No such link was found between these preg nancy complications and cerebral palsy in twins. For twins, a monochorionic plac enta (OR 1.9, 95%CI 1.0-3.6) increased the risk of cerebral palsy, but the OR became nonsignificant after adjustment (OR 1.7, 95%CI 0.8-3.4). CONCLUSION: In very preterm singletons, spontaneous preterm labor and PPROM increased the risk of cerebral palsy compared with hypertension.展开更多
