- Abstract : Aim: To determine IQ at 26 to 30 years in very‐low‐birthweight (VLBW) adults compared with term‐born controls; and to examine the stability of IQ in VLBW individuals between 7 to 8 years and 26 to 30 years, identify perinatal and social predictors of IQ, and assess the contribution of brain volume to IQ. Method: At 26 to 30 years, 229 VLBW adults (71% survivors of prospectively enrolled national cohort) and 100 term‐born controls were tested on the Wechsler Abbreviated Scale of Intelligence. For VLBW, IQ at 7 to 8 years, perinatal and social data were extracted from the data set, and 150 adults underwent volumetric cranial magnetic resonance imaging (MRI). Results: At 26 to 30 years, the mean adjusted difference between VLBW and controls for total IQ was 9.4 (95% CI 6.5–12.4) points. In VLBW individuals the correlation between IQ scores at 7 to 8 years and 26 to 30 years was 0.78. On multiple regression analysis, parental education was the strongest predictor of verbal and total IQ at both ages. Birthweight was a strong predictor of perceptual and total IQ. In VLBW individuals with MRI scans, the addition of brain volume as a variable increased the variance explained for perceptual and total IQ. Interpretation: VLBW adults have mean IQ scores 9 to 11 points below controls. Parental education and birthweight are the strongest predictors of IQ.

Predictores perinatales y en la infancia del resultado cognitivo general a los 28 años en una cohorte de nacional de muy bajo peso al nacer: Objetivo: Determinar el CI a 30 años de adultos nacidos con muy bajo peso al nacer (MBPN) comparados con un grupo control nacidos de término; y examinar la estabilidad del CI en individuos con MBPN entre 7 a 8 años y 26 y 30 años, identificando predictores de CI perinatales y sociales, y evaluar la contribución del volumen del cerebro y el CI. Método: A los 26 a 30 años, 229 adultos con MBPN (71% de supervivientes de la cohorte nacional inscripta de forma prospectiva) y 100 controles nacidos de término fueron evaluados con la escala de inteligencia abreviada Wechsler. Para los MBPN, el CI a los 7 a 8 años, los datos perinatales y sociales se extrajeron del conjunto de datos, y 150 adultos se sometieron a imágenes de resonancia magnética craneal volumétrica (MRI). Resultados: De 26 a 30 años, la diferencia media ajustada entre MBPN y controles para el CI total fue de 9, 4 (CI del 95%: 6, 5 a 12, 4) puntos. En los individuos MBPN la correlación entre los CI a los 7 ‐ 8 años y 26 a 30 años fue de 0.78. En un análisis de regresión múltiple, la educación de los padres fue el predictor más fuerte para el área verbal y el total del CI para ambas edades. El peso del nacimiento fue un fuerte predictor para el área perceptiva y el total del CI. En individuos con MBPN con RMN, el agregado del volumen cerebral como variable aumentó la varianza explicada para el área perceptiva y el total del CI. Interpretación: Adultos con MBPN tienen valores de CI 9 a 11 puntos menor que el grupo control. La educación paterna y el peso de nacimiento son fuertes predictores del CI. Preditores perinatais e da infância para o resultado cognitivo aos 28 anos de idade em uma coorte nacional de muito baixo peso ao nascimento: Objetivo: Determinar o QI dos 26 aos 30 anos em adultos com muito baixo peso ao nascimento (MBPN) comparados com controles nascidos a termo; identificar preditores perinatais e sociais do QI; e avaliar a contribuição do volume cerebral para o QI. Método: Aos 26 a 30 anos, 229 adultos MBPN (71% sobreviventes de uma coorte nacional prospectivamente recrutada) e 100 controles nascidos a termo forma testados com a Escala Wechsler Abreviada de Inteligência. Para MBPN, o QI aos 7‐8 anos, dados perinatais e sociais foram extraídos do conjunto de dados, e 150 adultos passaram por imagem por ressonância magnética (IRM) volumétrica cranial. Resultados: Aos 26 a 30 anos, a diferença média ajustada entre MBPN e controles para o QI total foi 9, 4 (IC 95% 6, 5–12, 4) ponto. Em indivíduos MBPN a correlação entre escores de QI aos 7‐8 anos e 26‐30 anos foi 0, 78. the correlation between IQ scores at 7 to 8 years and 26 to 30 years was 0.78. Na análise de regressão múltipla, a educação parental foi o mais forte preditor do QI verbal e total em todas as idades. O peso ao nascimento foi um forte preditor do QI perceptual e total. Em indivíduos com MBPN com exames de IRM, a adição do volume cerebral como variável aumentou a variância explicada pelo QI total e perceptual. Interpretação: Adultos MBPN têm escores de QI médios de 9 a 11 pontos abaixo dos controles. A educação parental e peso ao nascimento são os mais fortes preditores do QI. … (more)
