Wantedness of pregnancy and prenatal health behaviors.

This study examined the relationships between wantedness of pregnancy and the initiation of prenatal care as well as smoking and drinking alcohol during pregnancy. Three hundred and eighty post-partum women were interviewed in a randomly selected sample of Chicago area hospitals. Approximately half of the women said that they had wanted their recently completed pregnancy. Unadjusted analyses revealed that women who wanted their pregnancies were more likely to begin prenatal care in the first trimester and were less likely to smoke while there was no relationship between wantedness and alcohol use during pregnancy. After adjustment for sociodemographic variables, women who wanted their pregnancies were less likely to have smoked cigarettes or drunk alcohol during pregnancy, but were not more likely to have initiated prenatal care in the first trimester. These results suggest that positive health behaviors during pregnancy are influenced by wantedness of pregnancy as well as sociodemographic characteristics. Therefore, efforts to reduce unwanted pregnancies are an important strategy to improve the health of women and children.
