This report presents national estimates of sexual activity, contraceptive use, and births among males and females aged 15-19 in the United States in 2006-2010 from the National Survey of Family Growth (NSFG). For selected indicators, data are also presented from the 1988, 1995, and 2002 NSFG, and from the 1988 and 1995 National Survey of Adolescent Males, conducted by the Urban Institute.
Descriptive tables of numbers and percentages are presented and discussed. Data were collected through in-person interviews of the household population of males and females aged 15-44 in the United States, between July 2006 and June 2010. Interviews were conducted with 22,682 men and women, including 4,662 teenagers (2,284 females and 2,378 males). For both the teen subsample and the total sample, the response rate was 77%.
In 2006-2010, about 43% of never-married female teenagers (4.4 million), and about 42% of never-married male teenagers (4.5 million) had had sexual intercourse at least once. These levels of sexual experience have not changed significantly from 2002. Seventy-eight percent of females and 85% of males used a method of contraception at first sex according to 2006-2010 data, with the condom remaining the most popular method. Teenagers' contraceptive use has changed little since 2002, with a few exceptions: there was an increase among males in the use of condoms alone and in the use of a condom combined with a partner's hormonal contraceptive; and there was a significant increase in the percentage of female teenagers who used hormonal methods other than a birth-control pill, such as injectables and the contraceptive patch, at first sex. Six percent of female teenagers used a nonpill hormonal method at first sex.
本报告展示了来自全国家庭成长调查(NSFG)的2006 - 2010年美国15 - 19岁男性和女性性活动、避孕措施使用及生育情况的全国估计数据。对于选定指标,还展示了1988年、1995年和2002年NSFG以及城市研究所进行的1988年和1995年全国青少年男性调查的数据。
呈现并讨论了数量和百分比的描述性表格。数据通过2006年7月至2010年6月期间对美国15 - 44岁男性和女性家庭人口进行的面对面访谈收集。对22,682名男性和女性进行了访谈,其中包括4,662名青少年(2,284名女性和2,378名男性)。青少年子样本和总样本的回应率均为77%。
在2006 - 2010年,约43%从未结婚的女性青少年(440万)和约42%从未结婚的男性青少年(450万)至少有过一次性行为。这些性经历水平自2002年以来没有显著变化。根据2006 - 2010年数据显示,78%的女性和85%的男性在首次性行为时使用了避孕方法,避孕套仍然是最常用的方法。自2002年以来,青少年的避孕措施使用变化不大,有一些例外情况:单独使用避孕套以及将避孕套与伴侣的激素避孕方法结合使用的男性有所增加;首次性行为时使用除避孕药丸以外的激素方法(如注射剂和避孕贴片)的女性青少年百分比显著增加。6%的女性青少年在首次性行为时使用了非药丸类激素方法。
