Adolescent women who are sexually active often do not use contraceptives consistently and correctly. Adolescents are sexually active for an average of 15 months before initiating regular contraceptive use and the majority of young women who initiate use discontinue within the first year after initiation. This study enrolled 50 young women who initiated oral contraceptive use and was designed to provide more understanding of their perceptions about the possibility of an unplanned pregnancy and about contraceptive use. They were again contacted 6 weeks after initiation of oral contraceptives to assess continuation. Findings revealed that 90% of the subjects were sexually active at the time of the first visit; the mean period of sexual activity was 15 months. Only 30% had used a nonprescription birth control method during this period. While perceiving themselves to be highly susceptible to pregnancy, many young women continue to have psychosocial barriers to contraceptive use. Follow-up contact revealed more than 10% of the subjects were not using oral contraceptives.
有性行为的青春期女性往往不能持续、正确地使用避孕药具。青少年在开始常规使用避孕药具之前，平均有15个月的性活跃期，而且大多数开始使用避孕药具的年轻女性在开始使用后的第一年内就停止了。本研究招募了50名开始使用口服避孕药的年轻女性，旨在更深入了解她们对意外怀孕可能性和避孕药具使用的看法。在开始口服避孕药6周后再次联系她们以评估持续使用情况。研究结果显示，90%的受试者在首次就诊时处于性活跃状态；平均性活跃期为15个月。在此期间，只有30%的人使用过非处方避孕方法。尽管许多年轻女性认为自己极易怀孕，但在使用避孕药具方面仍存在心理社会障碍。随访发现，超过10%的受试者未在使用口服避孕药。
