In a longitudinal, prospective study, 95 children born to mothers who used cocaine and other drugs during pregnancy and 75 matched, nonexposed children born to mothers who had no evidence of alcohol or illicit substance use during pregnancy were evaluated for cognitive and behavioral outcome at 6 years of age. Prenatal exposure to cocaine and other drugs had no direct effect on the child's cognitive outcome (measured as IQ), but it had an indirect effect as mediated through the home environment. However, prenatal exposure to cocaine and other drugs did have a direct effect on the child's behavioral characteristics at 4-6 years of age, with the home environment having little impact. This study helps us to understand the fragile interaction of biological and environmental factors affecting the cognitive and behavioral development of children prenatally exposed to cocaine and other drugs.

Psychosomatic research findings correlating psychologic stress with diabetic control fail as yet to provide valid conclusions. Investigators have presented many contradictory findings. The two major pathways by which stress could affect control, a) changes in compliance behavior, and b) a neurohumoral axis, have not been clearly distinguished from each other. The study of adolescent cohorts is associated with the problem of heterogeneity, limiting the application of results to other diabetic populations. Methods of determining diabetic control have been incomplete and the definition and measurement of stress have major inadequacies for the analysis of such a complex psychosomatic problem. Existing evidence is comprehensively reviewed and evaluated. The authors use a modified definition of stress to construct a stress scale specific to pregnant diabetics.

The Short Form of the Beck Depression Inventory (BDI) was administered to 54 chemically dependent pregnant women to assess the extent and depth of depression in the population. The women were divided into three groups by age: Teenagers, young adults, and older adults. Results suggested that this population, as a whole, scored very high on this depression scale. Further, results indicated that the older chemically dependent women scored significantly higher on the depression index than did either of the two younger groups, while the teenagers obtained a mean score comparable to that of the general adolescent population.The negative effects of substance abuse o n maternal attachment and parenting are compounded by depression and anxiety in the pregnant addict. In this study, the Beck Depression Inventory (BDI) was used to assess the extent and depth of depressive symptomotology in a population of chemically dependent pregnant women.Requests for reprints should be addressed to Kayreen A.

A revised Prechtl Neurological Examination was administered to 510 singleton infants at term conceptional age to assess the influence of gestational age, race, and sex on neurobehavioral responses in a "typical" newborn population. The infants were born at 1 of 5 centers and were subjects of the NIH Collaborative Study on Antenatal Steroid Therapy. Of these babies, 392 were born at less than 37 weeks gestational age, whereas 118 infants were born at greater than or equal to 37 weeks. Of a total of 50 items of interest, 12 differed significantly based on race, 14 items differed in terms of gestational age at birth, and 5 items were influenced by the sex of the baby. These data suggest that singleton preterm infants born at differing gestational ages should not be considered to comprise a homogeneous sample. Further, caution should be exercised when considering babies of heterogeneous race groupings, and the babies' sex has minimal impact on neurobehavioral responses at term conceptional age.
