To determine American teenagers' awareness of and knowledge about emergency contraceptive pills and their likelihood to use them.
We conducted a nationally representative telephone survey between March 28, 1996, and May 5, 1996, of 1510 teenagers (757 girls and 753 boys), aged 12 to 18 years, living in the continental United States in households with telephones. The sample overrepresented African American, Latino, and low-income teenagers. The error attributable to sampling and other random effects for the total sample is +/-3 percentage points at the 95% confidence level.
Of the 1510 teenagers, only about one quarter (23%) were aware that "anything" could be done after unprotected sex to prevent pregnancy. Slightly more (28%) had heard of "morning-after pills" or emergency contraceptive pills. Of the 423 teenagers who had heard of emergency contraceptive pills, one third (32%) did not know that a prescription is necessary to obtain them, and three quarters (78%) underestimated how long after unprotected intercourse the emergency contraceptive pill regimen could be initiated. Only 9% knew that emergency contraceptive pills are effective as long as 72 hours after unprotected sex. After being told about the option of emergency contraceptive pills, two thirds (67%) of teenaged girls said that they would be likely to use emergency contraceptive pills. Among the 66% of teenaged girls who had not previously heard of emergency contraceptive pills, 64% said that they would be likely to use them.
Emergency contraceptive pills have great potential as a tool for reducing unplanned pregnancies among teenaged girls in the United States. Few teenaged girls were aware that this option exists. Once informed, teenaged girls reported being very interested in taking emergency contraceptive pills if needed.
确定美国青少年对紧急避孕药的知晓情况、相关知识以及使用的可能性。
1996年3月28日至5月5日,我们在美国本土有电话的家庭中,对1510名年龄在12至18岁的青少年(757名女孩和753名男孩)进行了一项具有全国代表性的电话调查。该样本中非洲裔美国人、拉丁裔和低收入青少年的比例过高。在95%置信水平下,总样本的抽样误差和其他随机效应误差为±3个百分点。
在1510名青少年中,只有约四分之一(23%)的人意识到在无保护性行为后“可以采取措施”预防怀孕。略多一些(28%)的人听说过“事后避孕药”或紧急避孕药。在423名听说过紧急避孕药的青少年中,三分之一(32%)不知道获取紧急避孕药需要处方,四分之三(78%)低估了在无保护性交后多久可以开始服用紧急避孕药方案。只有9%的人知道紧急避孕药在无保护性行为后长达72小时内都是有效的。在被告知有紧急避孕药这一选择后,三分之二(67%)的少女表示她们可能会使用紧急避孕药。在之前从未听说过紧急避孕药的66%的少女中,64%表示她们可能会使用。
紧急避孕药作为减少美国少女意外怀孕的工具具有巨大潜力。很少有少女意识到有这种选择。一旦得知,少女们表示如果有需要,对服用紧急避孕药非常感兴趣。
