Contraceptive failure--results from a study conducted among women with accepted and unaccepted pregnancies in Denmark.
Most studies focusing on contraceptive failure in relation to pregnancy have focused on contraceptive failure among women having induced abortions, thereby neglecting those women who, despite contraceptive failure, accept the pregnancy and intend to carry the fetus to term. To get a more complete picture of the problem of contraceptive failure, this study focuses on contraceptive failure among women with diverse pregnancy outcomes. In all, 3520 pregnant women attending Odense University Hospital were included: 373 had induced abortions, 435 had spontaneous abortions, 97 had ectopic pregnancies, and 2614 received antenatal care. The variables studied comprise age, partner relationship, number of births, occupational and economical situation, and contraceptive use.Contraceptive failure, defined as contraceptive use (condom, diaphragm, IUD, oral contraception, or another modern method) at the intercourse where conception most likely occurred, were reported by 315 women, 52% of these women had induced abortions, 10% had spontaneous abortions, 3% had ectopic pregnancies, and 36% received antenatal care. Women aged 15-24 years were more likely to have experienced contraceptive failure in relation to use of condom and oral contraception than women aged 25-34 years. In addition, contraceptive failure was found to be associated with being single, a student, and having given birth twice or more previously. Regarding pregnancy acceptance, being 25-34 years of age was positively associated, whereas being single and a student was negatively associated with pregnancy acceptance.
