Trends in HIV prevalence among disadvantaged youth. Survey results from a national job training program, 1988 through 1992.

OBJECTIVE
To describe trends in the prevalence of human immunodeficiency virus (HIV) among socially and educationally disadvantaged US youth.


DESIGN
Analysis of demographic and geographic trends of HIV infection among Job Corps students from January 1988 through December 1992.


SETTING
The Job Corps is a national training program for disadvantaged and out-of-school youth. POPULATION SCREENED: Youths aged 16 to 21 years who entered the Job Corps residential training centers during the survey period.


MAIN OUTCOME MEASURE
Trends in prevalence of HIV infection among Job Corps students stratified by sex, age, race, and region of the country.


RESULTS
Of the 269,956 Job Corps students screened, 812 (0.3%) tested positive for the antibody to HIV type 1. Seroprevalence of HIV for young men decreased from 3.6 per 1000 in 1988 to 2.2 per 1000 in 1992 (chi 2 test for trend, P < .001). Seroprevalence for young women increased from 2.1 per 1000 in 1988 to 4.2 per 1000 in 1990 (P = .001), with seroprevalence remaining stable from 1990 through 1992. The decreasing trends in HIV prevalence among men and increasing trends among women were primarily due to changes in seroprevalence in African-American students.


CONCLUSIONS
The overall prevalence of HIV infection of three per 1000 is high, given the youth of Job Corps students. The significant rise in HIV rates among female Job Corps students provides evidence of the increasing risk of infection for socioeconomically disadvantaged young women. Reasons for the declining trend in HIV prevalence among male Job Corps students are not clear. Efforts to prevent the spread of HIV infection among adolescents must focus on the group that is hardest to reach--out-of-school and impoverished youth.
