RODRIGUES, Maura Calixto Cecherelli de; MELLO, Rosane Reis de; SILVA, Kátia Silveira da  and  CARVALHO, Márcia Lazaro de. Risk factors for cognitive impairment in school-age children born preterm: application of a hierarchical model. Arq. Neuro-Psiquiatr. [online]. 2012, vol.70, n.8, pp.583-589. ISSN 0004-282X.

The purpose was to analyze factors associated with cognitive impairment in very low birth weight (VLBW) children born preterm. A prospective cohort of 65 VLBW children was assessed at the age of eight years using the Wechsler Intelligence Scale for Children. A model for the relationship of variables with the cognitive impairment outcome attributed hierarchical levels: distal (socioeconomic variables), intermediate I and II (perinatal and neonatal variables, post-neonatal variables) and proximal (child health and psychosocial stimulation). A multivariate logistic regression was performed. In the multivariate hierarchical logistic regression, the maternal education (OR=0.77, 95%CI 0.63-0.94) and number of prenatal visits (OR=0.73, 95%CI 0.54-0.99) showed a protective association, but the male (OR=7.3, 95%CI 1.54-35.3) was associated with worse results. The VLBW children cognitive performance in the age of eight years benefits from more educated mothers, better prenatal care, and the baby gender as female.
