Risk Factor Profiles of Adverse Neuromotor Outcome in Infants

Abstract

Objective Assessment of risk predictors for adverse neurodevelopmental outcome at 1 year of age in term and near-term infants. Material & Methods This case-control study was a representative sample of infants from different health-care centers of north and east of Tehran. The association between risk factors and delayed motor development (developmental quotient below 70 indicating a significant delay) was analyzed using correlating risk factors; including the perinatal and neonatal data to the developmental status. The case group consisted of 143 infants whose DQ score was less than 70 and the control group consisted of 140 infants who had a DQ score of more than 70. Results Neonatal seizures, Apgar score less than 3 after 5 minutes of birth (OR = 2.87 [95% CI; 1.68, 4.92]), low birth weight (OR = 5.86 [95% CI; 3.07, 11.18]), preterm delivery (OR =6.17 [95% CI; 3.04, 12.52]), Premature rupture of membranes (PROM)>24 hours (OR = 6.18[95% CI; 2.07, 18.51]) and hyperbilirubinemia leading to phototherapy or exchange transfusion (OR =3.75 [95% CI; 2.12, 6.65]) were associated with an increased risk for neuromotor delay on developmental examination at 1 year. Conclusion This study identified distinct risk factors for an adverse outcome in infants. In this environment, perinatal risk predictors are most important.
