Cognitive Functions and Behavioral Outcomes of Very Low Birth Weight Neonates in Middle Childhood
摘要
To assess the cognitive and behavioral outcomes of very low birth weight (VLBW) as compared to normal birth weight (NBW) neonates in middle childhood.
MethodsIn this observational study, the first 50 VLBW (≤ 1250 g) children from an original cohort of 2009–2011, who agreed to participate, and 50 age and sex-matched NBW children were assessed at 6–11 years age. Cognitive function, behavior, psychopathology, self-concept, adjustment and memory parameters were assessed by a certified psychologist using Malin's Intelligence Scale for Indian Children (MISIC), Childhood Psychopathology Measurement Schedule, Children’s Self-concept Scale, Preadolescent Adjustment Inventory, and PGI Memory Scale for Children (PGIMC), respectively.
ResultsCompared to NBW, the VLBW children had significantly lower Verbal Intelligence Quotient (IQ) (P = 0.008), Performance IQ (P < 0.001), and Full-Scale IQ (FSIQ) (P < 0.001). VLBW cohort had significantly lower scores in remote memory (P < 0.001), mental balance (P = 0.001), attention (P = 0.005), visual retention (P < 0.001), and recognition (P = 0.003). VLBW cohort exhibited significantly higher scores on psychopathology (P = 0.036), anxiety (P = 0.034), significantly lower self-concept (P < 0.001) and adjustment scores (P < 0.001) than NBW.
ConclusionsVLBW children have significant cognitive, behavioral and adjustment issues as compared to NBW children.
