Sexual behavior and selected health measures: men and women 15-44 years of age, United States, 2002.

OBJECTIVE: This report presents national estimates of several measures of sexual behavior among males and females 15-44 years of age in the United States in 2002, as collected in the 2002 National Survey of Family Growth (NSFG). These data are relevant to demographic and public health concerns, including fertility and sexually transmitted diseases among teenagers and adults. Data from the 2002 NSFG are compared with previous national surveys.

METHODS: The 2002 NSFG was conducted by the Centers for Disease Control and Prevention's (CDC) National Center for Health Statistics (NCHS) and is based on in-person, face-to-face interviews with a national sample of 12,571 males and females in the household population of the United States. The measures of sexual behavior presented in this report were collected using Audio Computer-Assisted Self-Interviewing (ACASI), in which the respondent enters his or her own answers into a laptop computer without telling them to an interviewer.

RESULTS: Among adults 25-44 years of age, 97 percent of men and 98 percent of women have had vaginal intercourse; 90 percent of men and 88 percent of women have had oral sex with an opposite-sex partner; and 40 percent of men and 35 percent of women have had anal sex with an opposite-sex partner. About 6.5 percent of men 25-44 years of age have had oral or anal sex with another man. Based on a differently worded question, 11 percent of women 25-44 years of age reported having had a sexual experience with another woman. The public health significance of the findings is described.
