Prematurity has been identified as a risk factor for development of autism spectrum disorder (ASD). The aim of the present study was to perform a screening for autistic features in children with a history of preterm birth and to correlate with pregnancy, obstetric and neonatal complications. This study enrolled 37 infants, with gestational age < 34 weeks who had been admitted at Obstetric Center of Hospital do Servidor Público Estadual de São Paulo - Francisco Morato de Oliveira, from July 2005 to March 2007. Information of pregnancy, labor, delivery and neonatal complications were obtained from medical records at Neonatal Intensive Care Unit and the Office of Medical File (SAME). Follow-up assessment was performed when the children reached between 4 and 5 years of age, using Autism Behavior checklist (ABC). The gestational age at birth ranged from 24 to 34 weeks, and birth weight average was1655 + 613 g. The maternal age average was 33.5 + 8 years old. Approximately 56% and 100% of infants scored Apgar > 7 at one and five minutes, respectively. Birth conditions and perinatal complications show no differences between the sex groups, except that in favor of females, she were more likely to get higher Apgar scores at five minutes and body birth weight. Cyanosis and fetal distress were associated with increased risk of Apgar score <7 at one minute in preterm infants with birth weight <1500g. Immaturity was associated with increased risk for Apgar score <7 at one minute and bronchopulmonary dysplasia. Negative screening for autism spectrum disorder in this casuistic was primarily due to small sample size, limiting factor in this study, and secondly, the absence of certain characteristics in the casuistic. The literature assumes that maternal and neonatal morbidities, as gestational age < 26 weeks, very low birth weight infant, preeclampsia, being born small for gestational age, congenital malformations and low Agar score at five minutes and intracranial bleeding are strongly associated with autistic disorders in preterm birth.
