随着越来越多感染艾滋病毒的人寿命更长、生活更健康，对继续传播的关切日益增加，同时人们也认识到需要发展“阳性预防”。这项针对纽约市艾滋病毒阳性成年人的研究，首次对一大批具有代表性的艾滋病毒感染者的性行为模式进行了长时间的研究。在1994年至2002年期间，每隔6-12个月对968名艾滋病毒阳性的成年人进行一次访谈，并报告说随着时间的推移，性行为发生了相当大的变化。许多人在几个月的时间里根本没有性生活；有些人仍然有多个伴侣。超过三分之一的人与艾滋病毒阴性或身份不明的伴侣发生过一次或多次无保护的性行为（不安全性行为），五分之一的人报告发生过性行为。不安全性行为的时期与安全性行为的时期交替进行。性风险的预测因子因性别而异，在与男性发生性行为的男性和只与女性发生性行为的男性之间也有差异。伴侣关系、住房状况和接受艾滋病毒服务等环境因素与个人属性一样重要，都是不安全性行为和性交易的预测因素。随着时间的推移，在性危险行为中观察到的可变性为让艾滋病毒感染者参与正在进行的预防计划的重要性提供了新的见解。
As an ever-increasing number of people infected with HIV are living longer, healthier lives, concerns about continued transmission are growing along with an awareness of the need to develop "prevention for positives." This study of HIV-positive adults in New York City is the first examination of patterns of sexual behavior in a large, representative cohort of HIV-infected individuals followed over an extended time period. A total of 968 HIV-positive adults were interviewed every 6-12 months between 1994 and 2002 and reported considerable variability in sexual behaviors over time. Many persons were not sexually active at all for months at a time; some continued to have multiple partners. Over one third of the cohort had one or more periods when they had engaged in unprotected sex with a partner who was HIV-negative or status unknown (unsafe sex) and one in five reported exchanging sex. Periods of unsafe sex alternated with periods of safer sex. Predictors of sexual risk varied by gender, and among men who had sex with men, and men sexually active with women only. Contextual factors such as partner relations, housing status, and receipt of HIV services were as important as individual attributes as predictors of unsafe sex and sex exchange. The variability observed in sexual risk behavior reported over time provides new insight into the importance of engaging persons living with HIV in ongoing prevention programs.
