Abstract: Aim. - The purpose of this population-based study was to compare the incidence of neurodevelopmental disability and its risk factors between preterm and full-term infants matched as control group. Population and methods. - The preterm cohort included 203 infants born between 25 and 33 weeks of gestational age in the region of Franche-Comte' (France) during a two-year-period. The control group included 196 full-term infants born in the same maternities. Sunrvival up to the date of follow-up, was 171/203 (84%) for preterms and 195/196 (99.5%) for full-term infants (uncorrected age, mean 12 months). Neurodevelopmental assessements were performed by pediatricians or physicians on 164/171 surviving preterms (96% follow-up) and 179/195 full-terms (92%). Results. - Thirty-two (19.5%) preterm infants had disability, ten of these (6%) showing severe disability. Five (2.8%) full-term infants had disability, one of these (.5%) having severe disability. Risk factors predicting a disability included in a multivariate approach: prematurity (odds-ratio [OR]: 7.8), maternal age > 37 (OR: 3.0), lack of profession for both parents (OR: 3.7), male gender (OR: 2.9). The pediatrician observed a disability more frequently than the physician (OR: 2.46). Likewise, risk factors predicting a severe disability included: prematurity (OR: 10.8), lack of profession for both parents (OR: 5.8) and monochorial twin-placentation (OR: 4.5). Conclusions. - Prematurity is not the only risk factor to be taken into account for neurodevelopmental evaluation of premature infants, but its influence still remains widely predominant.
