Factors related to cigarette smoking during adolescent pregnancy.

Previous research suggests that maternal smoking during pregnancy remains prevalent, particularly among adolescents. However, little is known about the factors related to smoking during adolescent pregnancy. The goal of the present study is to identify intrapersonal, familial, and peer factors that are related to smoking during adolescent pregnancy, and to determine the relative degree to which they affect this behavior. Interviews were conducted with 241 unmarried pregnant adolescents who planned to carry their pregnancies to term. Consistent with previous studies, 27% of the respondents reported daily smoking during pregnancy, and whites reported higher rates of use than members of other racial groups. Smoking during adolescent pregnancy was related to intrapersonal, familial, and peer factors. The results of a regression analysis suggest that perceived parental disapproval of smoking during pregnancy, friends' cigarette use, and race play a particularly important role in this behavior. The implications of these findings for preventive programs are discussed.
