INTRODUCTION AND AIMS
Data are lacking on drug use among gay and bisexual men (GBM) in New Zealand. We establish a baseline estimate of drug use and investigate associations with sexual health and HIV risk.
DESIGN AND METHODS
A cross-sectional survey of GBM was conducted in gay community settings and online. Participants were asked their frequency of using nine drugs (poppers, cannabis, ecstasy, methamphetamine, amphetamine, cocaine, LSD, gamma hydroxybutyrate and ketamine) in the previous 6 months. We examined associations between selected drugs and number of recent partners, unprotected anal intercourse with a casual partner and sexually transmitted infections using adjusted odds ratios (AOR).
RESULTS
Overall, 3211 participants provided information of whom 55.8% reported any drug use, and 37.9% cannabis, 36.7% poppers, 16.5% ecstasy, 10.5% amphetamine, 7.4% methamphetamine, 6.6% LSD, 6.1% cocaine, 5.3% gamma hydroxybutyrate and 4.4% ketamine use. A quarter of all respondents (25.6%) reported using one drug, 22.8% two to four and 7.4% five or more drugs (polydrugs). Methamphetamine and polydrug use was independently predictive of reporting >20 recent partners (AOR 1.6 and 7.0, respectively), unprotected anal intercourse with a casual partner (AOR 1.8 and 3.2, respectively) and a sexually transmitted infection (AOR 1.6 and 4.3, respectively).
DISCUSSION AND CONCLUSIONS
Drug use was common in this sample of GBM. Polydrug and methamphetamine users had especially high sexual health needs, but risks remained elevated among GBM consuming other drugs. Drug harm reduction programs and HIV prevention should target GBM with problematic drug use. Limitations include an inability to attribute causation.

引言和目的
新西兰缺乏男同性恋和双性恋者（GBM）的药物使用数据。我们建立了一个药物使用的基线估计，并调查了与性健康和 HIV 风险的关联。
设计和方法
在同性恋社区环境和在线对 GBM 进行了横断面调查。参与者被要求报告他们在过去 6 个月中使用九种药物（啪啪剂、大麻、摇头丸、冰毒、苯丙胺、可卡因、LSD、γ-羟基丁酸和氯胺酮）的频率。我们使用调整后的优势比（AOR）检查了选定药物与最近伴侣数量、与偶然伴侣无保护肛交和性传播感染之间的关联。
结果
共有 3211 名参与者提供了信息，其中 55.8%报告了任何药物使用，37.9%使用大麻，36.7%使用啪啪剂，16.5%使用摇头丸，10.5%使用苯丙胺，7.4%使用冰毒，6.6%使用 LSD，6.1%使用可卡因，5.3%使用γ-羟基丁酸，4.4%使用氯胺酮。所有受访者中有四分之一（25.6%）报告使用了一种药物，22.8%使用了两种到四种药物，7.4%使用了五种或更多药物（多药物）。冰毒和多药物使用独立预测报告了 >20 名最近伴侣（AOR 分别为 1.6 和 7.0）、与偶然伴侣无保护肛交（AOR 分别为 1.8 和 3.2）和性传播感染（AOR 分别为 1.6 和 4.3）。
讨论和结论
在这个 GBM 样本中，药物使用很常见。多药物和冰毒使用者的性健康需求特别高，但其他药物使用者的风险仍然很高。药物危害减少计划和 HIV 预防应针对有问题药物使用的 GBM。限制包括无法归因于因果关系。[Saxton P、Newcombe D、Ahmed A、Dickson N、Hughes A. 新西兰男同性恋和双性恋者的非法药物使用：流行情况和与性行为健康行为的关联。药物和酒精评论 2017;00:000-000]。
