PATTERNS AND COVARIATES OF TOBACCO USE IN A RECENT SAMPLE OF PREGNANT TEENAGERS

Purpose. Little is known about the prevalence and patterns of smoking among pregnant teenagers. We provide a comprehensive description of the prevalence, patterns and correlates of smoking from a recent sample of 199 pregnant adolescents. Methods. We interviewed pregnant teenagers at midpregnancy and delivery to obtain information on tobacco and other substance use before and during pregnancy and on demographic, medical and psychosocial status. Results. The average age was 16.1 years (range 12-18); 70% were African-American. Smoking was prevalent and increased from first (59%) to third (62%) trimesters. This increase was in sharp contrast to decreases in other substances. Caucasians had higher rates of smoking and heavier smoking. For Caucasians, third trimester smoking was predicted by peer smoking and early onset of sexual activity. For African-Americans, third trimester smoking was related to older age, not living with parent(s), dissatisfaction with social support, early pregnancy binge drinking, peer smoking, and early onset of sexual activity. Conclusions. The high prevalence and increasing pattern of prenatal smoking in teenagers is a major public health concern. Effective education and cessation programs must be targeted at pregnant teenagers.
