This study examined determinants of unintended pregnancy in the US. Data were obtained from the 1995 National Survey of Family Growth among 7221 women 15-44 years old at risk of unintended pregnancy. Findings indicate that adolescents were not mainly sporadic method users in 1995. Most used a method without interruption for an extended period. Teenagers were more likely to report sporadic contraceptive use and were less likely to be uninterrupted users of effective methods. Women 20-24 years old were no more likely than 18-19 year old women to report long-term sporadic use and were more likely than women 25-34 years old to report long-term sporadic use. Nonusers and sporadic users contributed significantly to the high rate of unintended pregnancies. Logistic models reveal that women who were married or cohabiting were more likely to be uninterrupted effective contraceptive users than those not in long-term relationships. Frequency of intercourse had a consistent, strong positive relationship with contraceptive use. Women who had nonvoluntary intercourse and teenagers with significantly older partners were less likely to use contraceptives. Condoms are appropriate for infrequent intercourse, but couples must know the risks of pregnancy even with infrequent intercourse and know about postcoital methods of pregnancy prevention.
