Neurodevelopment at two years and appropriate schooling at five years in children born very preterm

Aim: This single-centre French cohort study evaluated the relationship between standardised assessment at 2 years of corrected age and schooling level at 5 years of age in children born at ≤32 weeks' gestational age.

Methods: This was a single-centre retrospective study of children born preterm between 2010 and 2014 included in a follow-up network. At 5 years of age, the population was divided into 2 groups: (1) 'appropriate schooling', defined as age-appropriate schooling without support, and (2) 'schooling with support'. At 2 years of corrected age, the developmental quotient (DQ) was calculated using the revised Brunet-Lezine test. Neonatal variables and DQ categories were compared between the 2 groups on univariate and multivariate analyses.

Results: DQ was available for 251 of the 270 children included (93%), with a median score of 93.0 (IQR [87.0-100.0]), and 171 children (68%) were in the schooling without support group. On multivariate analysis, DQ ≥100 (n = 67) was the only variable that significantly associated with schooling without support (OR = 13.9; 95% CI: 5.5-35.4) at 5 years of age.

Conclusion: This result may be useful for clinicians in their routine practice and for information given to parents in neonatal follow-up.
