We estimated HIV prevalence rates among young adults in the United States.
We used survey data from the third wave of the National Longitudinal Study of Adolescent Health, a random sample of nearly 19000 young adults initiated in 1994-1995. Consenting respondents were screened for the presence of antibodies to HIV-1 in oral mucosal transudate specimens. We calculated prevalence rates, accounting for survey design, response rates, and test performance.
Among the 13184 participants, the HIV prevalence rate was 1.0 per 1000 (95% confidence interval [CI] = 0.4, 1.7). Gender-specific prevalence rates were similar, but rates differed markedly between non-Hispanic Blacks (4.9 per 1000; 95% CI=1.8, 8.7) and members of other racial/ethnic groups (0.22 per 1000; 95% CI=0.00, 0.64).
Racial disparities in HIV in the United States are established early in the life span, and our data suggest that 15% to 30% of all cases of HIV occur among individuals younger than 25 years.
我们估算了美国年轻成年人中的艾滋病毒流行率。
我们使用了青少年健康全国纵向研究第三波的调查数据,该研究于1994 - 1995年对近19000名年轻成年人进行了随机抽样。同意参与的受访者接受了口腔黏膜渗出液样本中HIV - 1抗体的筛查。我们计算了流行率,并考虑了调查设计、应答率和检测性能。
在13184名参与者中,艾滋病毒流行率为每1000人中有1.0例(95%置信区间[CI]=0.4, 1.7)。按性别划分的流行率相似,但非西班牙裔黑人(每1000人中有4.9例;95% CI = 1.8, 8.7)与其他种族/族裔群体成员(每1000人中有0.22例;95% CI = 0.00, 0.64)之间的流行率差异显著。
美国艾滋病毒方面的种族差异在生命早期就已存在,我们的数据表明,所有艾滋病毒病例中有15%至30%发生在25岁以下的人群中。
