The American Men's Internet Survey (AMIS) is conducted annually with 10,000 men age 15 + who have sex with men (MSM). Modeling was used with 39,863 AMIS surveys from 4 cycles between December 2013 to February 2017 to identify temporal trends in sexual behavior, substance use, and testing behavior (within 12 months preceding interview) stratified by participants' self-reported HIV status. HIV-negative/unknown status MSM had significant increases in condomless anal intercourse (CAI), marijuana use, use of other illicit substances, sexually transmitted infection (STI) diagnoses, and HIV or STI testing (testing only increased among MSM age 25 +). HIV-negative/unknown status MSM had significant decrease in CAI with an HIV-positive or unknown status partner. HIV-positive MSM had significant increases in CAI, methamphetamine use, and STI diagnoses/testing. Although encouraging, the few indicators of improvement in HIV/STI sexual health practices are not consistently seen across sub-groups of MSM and may be counteracted by growing proportions of MSM engaging in CAI and acquiring STIs.
美国男性互联网调查（AMIS）每年对 10000 名年龄在 15 岁及以上的与男性发生性关系的男男性接触者（MSM）进行调查。利用 2013 年 12 月至 2017 年 2 月期间的 4 个周期中 39863 份 AMIS 调查数据，对性行为、物质使用和检测行为（在接受采访前 12 个月内）进行建模，根据参与者自我报告的 HIV 状况对这些数据进行分层。HIV 阴性/未知状态的 MSM 中，无保护肛交（CAI）、大麻使用、其他非法物质使用、性传播感染（STI）诊断以及 HIV 或 STI 检测（仅在 25 岁及以上的 MSM 中增加）的比例显著增加。HIV 阴性/未知状态的 MSM 与 HIV 阳性或未知状态的伴侣发生 CAI 的比例显著下降。HIV 阳性的 MSM 中 CAI、冰毒使用和 STI 诊断/检测的比例显著增加。尽管令人鼓舞，但 HIV/STI 性健康行为方面的少数改善指标并未在 MSM 的各个亚组中一致出现，并且可能会被越来越多的从事 CAI 和感染 STI 的 MSM 所抵消。
