Factors influencing first intercourse for teenage men

Analyses of a nationally representative survey of 1,880 15- to 19-year-old men were conducted to examine factors associated with (a) the age when first sexual intercourse occurred and (b) whether a condom or other contraceptive method was used at first intercourse. Discrete time-event history models assessed factors influencing their age until first intercourse. Black males began sexual activity significantly earlier than white or Hispanic males. Males who had been held back in school also began sexual activity earlier. If a respondent's mother had been a teenager when she first gave birth, or if his mother was employed during his childhood, he was more likely to initiate intercourse early. A variety of combinations of AIDS and sex education topics were examined for their association with one's age at the time of first intercourse: two topics were associated with earlier intercourse, and one was associated with delays in first intercourse. Logistic regression models examined correlates of using a condom or any effective male or female method of contraception at first intercourse: having received education about birth control was marginally associated with increased probability of using a condom or any effective male or female contraceptive method at first intercourse. These findings indicate the relevance of integrated approaches to school-based sex and AIDS education in delaying intercourse and promoting use of contraceptive methods.
