Fertility and Oral Contraceptive Use Study (FOCUS) (ICPSR 34560)

Scope of Study
Summary: Oral contraceptives (OCs) are the most popular reversible method of contraception in the United States. Although most women using OCs experience reliable protection against pregnancy, nearly half of the 3 million unintended pregnancies in the United States annually occur among the 90 percent of women who use contraception. While lack of adherence to OCs has been assumed to be the primary cause of OC failure, recent findings suggest that obesity may reduce the biological effectiveness of OCs. The goal of this project was to examine methodological issues related to the successful implementation of a large, prospective cohort study to investigate the role of obesity in OC failure.
