Alcohol use as a situational influence on young women's pregnancy risk-taking behaviors.

Recent studies have found that many young women just beginning their sexual lives use alcohol prior to intercourse. A large number appear to drink heavily enough prior to sex to compromise their ability to use contraceptives. The question emerges whether there is a relationship between drinking before intercourse, the nonuse of birth control methods, and unplanned pregnancies. The present research describes 43 instances of intercourse which resulted in unplanned pregnancies in 14- to 21-year-olds. Variables examined included alcohol use prior to sex, amount of alcohol consumed, the use of other drugs, the planning of intercourse, respondents' stated reasons for nonuse of contraceptives, and other general demographic data.
