Latino adolescents in two urban New England areas were surveyed to assess risk of human immunodeficiency virus (HIV) transmission.
Probability of HIV infection during the previous 6 months was estimated from self-reported sexual contacts, condom usage rates, and number of partners. Teens were also asked to show condoms in their possession to the interviewer to validate self-reports of condom use.
Overall, 8% of the 586 respondents were classified as high risk for HIV infection (estimated infection probability greater than .0001), 34% were at moderate risk, and the remaining 58% were classified as not at risk (no sexual activity or needle sharing). Teens who said they had purchased condoms or claimed to have used them recently were more likely than others to have condoms in their possession at the time of the interview.
These estimates suggest that a small percentage of Latino adolescents may be at substantial risk for HIV infection over periods as short as 6 months, that self-reports of recent condom use are strongly related to condom possession, and that questionnaire items regarding condom use at last intercourse are poor surrogates for HIV risk.
对新英格兰地区两个城市的拉丁裔青少年进行调查，以评估人类免疫缺陷病毒（HIV）传播风险。
根据自我报告的性接触情况、避孕套使用率和性伴侣数量，估算过去6个月内感染HIV的概率。青少年还被要求向采访者展示他们持有的避孕套，以验证其对避孕套使用情况的自我报告。
总体而言，586名受访者中，8%被归类为HIV感染高风险人群（估计感染概率大于0.0001），34%为中度风险，其余58%被归类为无风险（无性行为或共用针头）。表示最近购买过避孕套或声称使用过避孕套的青少年，在接受采访时持有避孕套的可能性比其他人更大。
这些估计表明，一小部分拉丁裔青少年在短短6个月内可能面临相当大的HIV感染风险，近期避孕套使用情况的自我报告与持有避孕套密切相关，且关于最后一次性交时避孕套使用情况的问卷项目并不能很好地反映HIV风险。
