Abstract
This study aimed to examine trajectories with respect to the number of sexual partners among older men who have sex with men and to determine characteristics associated with trajectory groups. Nagin's group-based modeling was used to identify trajectories for 237 men from the Pitt Men's Study with respect to the number of male intercourse partners from age 50.0 to 59.5. Three distinct trajectory groups were identified. Most men (69.2%) had a median of two sexual partners in the past 6 months across the age range of the study. A smaller group (19.4%) had low or no sex partners. The smallest group (11.4%) had 30 or more sexual partners in the past 6 months at age 50. The groups were statistically different with respect to race, HIV status, drug use (marijuana, poppers, crack cocaine, and Viagra), the number of unprotected anal sex partners, and personal attitudes towards sex.
摘要
这项研究旨在探讨男男性行为者中老年男性性伴侣数量的变化轨迹，并确定与轨迹群体相关的特征。本研究采用纳金的基于群组的建模方法，对来自匹兹堡男性研究的 237 名男性在 50 岁至 59.5 岁期间的男性性交伴侣数量进行了轨迹分析。研究结果识别出了三个不同的轨迹群体。在研究期间，大多数男性（69.2%）在过去 6 个月中有中位数为两个性伴侣。较小的群体（19.4%）性伴侣较少或没有。最小的群体（11.4%）在 50 岁时过去 6 个月中有 30 个或更多的性伴侣。在种族、HIV 状况、药物使用（大麻、啪啪粉、可卡因和伟哥）、无保护肛交伴侣数量以及对性的个人态度方面，这些群体存在统计学差异。
