Attrition rates per litter (prenatal loss, neonatal loss) and pup weights were comparable between groups.
Postneonatal death rates were higher for African American women than white women in the presence (3.8 vs 1.7 per 1000) and absence (11.2 vs 5.3 per 1000) of prenatal care.

*Values are per 100 000 pregnancies in prenatal care for an overall 90% detection of cases of Down's syndrome.
We found a significant increase in growth associated with p,p´ -DDE, seemingly due to prenatal exposure (per interquartile increase in exposure, adjusted β = 0.12; 95% CI: 0.03, 0.22).
Women who had missing, inadequate and intensive levels of prenatal care per the Kotelchuck index had increased odds of having a preterm baby as compared to women with an adequate level of prenatal care (Table 2).
In the second year, teams from Aswan District raised the number of prenatal visits per woman from 1.3 to 3.7, and child care visits increased from 1.1 to 3.5.
Based on our earlier work [ 18], the following additional steps were carried out: We identified the relationships between the main exposure (≥4 drinks per day) and the prenatal maternal and socio-demographic and child variables outlined above (Table 1 ).
The case mother reported eating canned ravioli daily during her second and third trimesters of pregnancy and eating canned or frozen vegetables one to three times per week in her prenatal questionnaire.
