This study describes changes over a 12-month period in prevalence and frequency of alcohol and other drug use and correlates of change at 12 months in a sample of gay/bisexual men entering gay-identified outpatient substance abuse treatment.
A sequential sample of gay/bisexual men (n = 455) were recruited for a study in which substance use, sexual risk and psychological factors were assessed every 3 months. Changes in substance use were evaluated in 321 men who used in the 90 days before entering treatment and who completed at least one follow-up interview, whether or not they continued in treatment.
At baseline, 95% of the sample reported alcohol use in the prior 90 days; 64%, marijuana/hashish use; 46%, amphetamine use; 33%, inhalant nitrites use; and 31%, cocaine use. Most men were polydrug users: 10% reported using only one drug (including alcohol); 39% used > or = 4 drugs. A marked reduction occurred in prevalence of use over time; declines on the order of 50% occurred in the first 90 days; prevalence then stabilized in remaining assessments. Frequency of usage by those reporting use of any given class of drugs also declined. No consistent predictors of reduction or cessation of use across different drug categories were found at 1 year.
Substance use declined considerably in this sample. Given the scope of substance abuse problems among gay/bisexual men, and linkages to the HIV epidemic, considerable resources need to be focused on treatment and prevention for gay/bisexual men.
本研究描述了在为期12个月的时间里，进入以同性恋者为对象的门诊药物滥用治疗的男同性恋者/双性恋男性样本中酒精及其他药物使用的流行率和频率变化，以及12个月时变化的相关因素。
招募了一个男同性恋者/双性恋男性的连续样本（n = 455）进行一项研究，在该研究中每3个月评估一次药物使用、性风险和心理因素。对321名在进入治疗前90天内使用过药物且至少完成了一次随访访谈的男性进行了药物使用变化评估，无论他们是否继续接受治疗。
在基线时，95%的样本报告在之前90天内饮酒；64%报告使用大麻/哈希什；46%报告使用安非他命；33%报告使用吸入性亚硝酸盐；31%报告使用可卡因。大多数男性是多药使用者：10%报告仅使用一种药物（包括酒精）；39%使用≥4种药物。随着时间的推移，使用流行率显著下降；在最初90天内下降了约50%；此后在其余评估中流行率稳定下来。报告使用任何特定类别的药物的人的使用频率也下降了。在1年时，未发现不同药物类别使用减少或停止的一致预测因素。
该样本中的药物使用大幅下降。鉴于男同性恋者/双性恋男性中药物滥用问题的范围以及与艾滋病毒流行的关联，需要将大量资源集中于男同性恋者/双性恋男性的治疗和预防。
