title: The predictive significance of biologic risk factors for deficits in children of a high-risk population.
abstract: Two hundred forty-two high-risk children and 47 low-risk children were prospectively studied to assess the relationship between biologic risk factors that occurred during the perinatal period and the motor and cognitive deficits that were identified during the first year of life. Multiple risk factors were present in 80% of the children of the high-risk group. Provisional deficits were classified on the degree of abnormality found in a clinical and behavioral assessment that included neurological examinations, Bayley Physical and Mental Development Scales, and the Uzgiris and Hunt Scale. Provisional deficits occurred in 10% of the children of the low-risk group. High-risk children had a significantly greater incidence of provisional deficits, particularly in respect to positive deficits. In high-risk children, the probability of a deficit was 17% in those without infection or encephalopathy, 30% in those with infection, and 40% in those with encephalopathy.
