Prenatal exposure to seven heavy metals (cadmium, chromium, cobalt, lead, mercury, nickel, and silver) was determined for amniotic fluid taken from 92 pregnant women undergoing amniocentesis at ...approximately 16 to 18 weeks' gestation. Follow-up assessment of their children's cognitive skills and health status was conducted when the children were approximately 3 years of age. The presence of these metals co-occurred in amniotic fluid. A prenatal toxic risk score was derived which was a weighted score reflecting the presence of the various metals in amniotic fluid. The toxic risk score was negatively related to performance on the McCarthy Scales of Children's Abilities and positively related to the number of child illnesses reported. These results suggest the need for further prospective research on the adverse effects of prenatal exposure to various metals in combination.
Although reports of individual differences in reactivity have recently emerged in the literature, information is still lacking on the ontogeny and stability of this phenomenon over the first months ...of life. To address this issue, the responses of 40 newborns to PKU screening at 2 days of age were videorecorded. At 2 months, when the infants received their first DPT shot, their behavior in response to the inoculation was also videorecorded. Besides duration of crying, the intensity of fussing and grimacing was determined. Irrespective of birth characteristics, measures of reactivity were related over the first 2 months of extrauterine life.
The link between behavioral responsiveness to stress and subsequent health has been demonstrated in adults but not in infants and very young children. The ability of infants to suppress responding to ...acutely painful events was examined both as a function of neonatal status and as a predictor of incidence of illness at 18 to 24 months. Responding to stress in early infancy was predictive of later health but the nature of the relation depended on the maturity of the child.

The influence of feeding method on infant development has been a topic of interest for much of this century. While the nutritional benefits of breast feeding on physical growth are virtually ...undeniable, associations between method of feeding and infant behavior have been surprisingly inconsistent; the question to be addressed here focuses on exploring the usefulness of the current procedures in differentiating infants who have been breast fed from those who have been bottle fed
Studied individual differences in reactivity in 40 newborns. Measures of reactivity were related during the first two months of extrauterine life. (RJC)
