Sexual initiation with older male partners and subsequent HIV risk behavior among female adolescents.

Data from a 1993-1994 survey of 150 black and Hispanic teenagers were used to examine differences in HIV risk-related behavior between young women who have a first sexual partner three or more years older than themselves and those whose first partner is their age. Compared with teenagers whose first partner had been roughly their age, the 35% of adolescents with an older partner had been younger at first intercourse (13.8 years vs. 14.6) and less likely to use a condom at first intercourse (63% vs. 82%). They also were less likely to report having used a condom at last intercourse (29% vs. 44%) or having used condoms consistently over their lifetime (37% vs. 56%) or in the previous six months (44% vs. 66%). Some 38% of teenagers with an older first partner had ever been pregnant, compared with 12% of those with a peer-age first partner. The mean number of partners and history of sexually transmitted diseases did not differ between the two groups.
