目的
本报告介绍了2006-2008年美国15-19岁男性和女性的性活动、避孕药具使用和生育的全国估计数，来自全国家庭增长调查（NSFG）。选定的数据也从1988年，1995年和2002年的NSFG，从1988年和1995年的全国青少年男性调查（NSAM），城市研究所进行。
方法
描述表的数字和分量的介绍和讨论。数据是通过2006年7月至2008年12月对美国家庭人口进行的面对面访谈收集的。对7，356名女性（其中1，381名为青少年）和6，140名男性（其中1，386名为青少年）进行了访谈，共计2，767名青少年。2006-2008年《国家森林论坛》的总体答复率为75%。女性青少年的答复率为77%，男性青少年为75%。
结果
2006-2008年，约42%的未婚少女（430万人）和约43%的未婚男青少年（450万人）至少有过一次性行为。自2002年NSFG上次收集这些数据以来，这些性经验水平没有显着变化。在从未结过婚的青少年中，79%的女性和87%的男性在第一次性行为时使用避孕方法。除了少数例外，自2002年以来，青少年使用避孕药具的情况变化不大，避孕套仍然是最常用的方法。一个例外是，男性使用避孕套和避孕套与激素避孕药结合使用（双重方法使用）的情况有所增加。另一个例外是使用过定期禁欲或“日历节律”方法的女性青少年的百分比显著增加。2006-2008年，17%的少女使用了这种方法。
OBJECTIVE
This report presents national estimates of sexual activity, contraceptive use, and births among males and females 15-19 years of age in the United States in 2006-2008 from the National Survey of Family Growth (NSFG). Selected data are also presented from the 1988, 1995, and 2002 NSFGs, and from the 1988 and 1995 National Survey of Adolescent Males (NSAM), conducted by the Urban Institute.
METHODS
Descriptive tables of numbers and percents are presented and discussed. Data were collected through in-person interviews of the household population in the United States, conducted between July 2006 and December 2008. Interviews were conducted with 7,356 females-1,381 of whom were teenagers--and 6,140 males--1,386 of whom were teenagers-for a total of 2,767 teenagers. The overall response rate for the 2006-2008 NSFG was 75%. The response rate for female teenagers was 77% and for male teenagers 75%.
RESULTS
In 2006-2008, about 42% of never-married female teenagers (4.3 million), and about 43% 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, the last time the NSFG collected these data. Among never-married teenagers, 79% of females and 87% of males used a method of contraception at first sex. With a few exceptions, teenagers' use of contraceptives has changed little since 2002, and the condom remained the most commonly used method. One exception was an increase in the use of condoms and the use of a condom combined with a hormonal contraceptive (dual method use) among males. Another exception was a significant increase in the percent of female teenagers who had ever used periodic abstinence, or the "calendar rhythm" method. This method had been used by 17% of female teenagers in 2006-2008.
