Adolescent gay and bisexual men (AGBM) are disproportionately affected by human immunodeficiency virus (HIV), but little is known about testing rates among men aged 18 years and under or about the barriers that they face when contemplating an HIV test. Therefore, we investigate here the testing behaviors and barriers among a diverse national sample of AGBM.
A total of 302 AGBM aged 14-18 years were recruited via Facebook ads to participate in an mHealth (text messaging-based) HIV prevention program. Recruitment was stratified to ensure approximately 50% were sexually inexperienced.
Only 30% of sexually active participants had ever been tested for HIV, and nearly half of them did not know where they could go to get tested for HIV (42.9%). Based on exploratory factor analysis, nine questions assessing potential barriers to HIV testing factored into three subscales: external factors, fear, and feelings of invincibility. Among sexually active participants, those who had never tested for HIV had significantly greater scores on the external factors (odds ratio, 1.63; 95% confidence interval, 1.01-2.66) and fear (odds ratio, 1.88; 95% confidence interval, 1.11-3.19) subscale. Older (16-18 years old) youth were especially likely to be affected by external factor barriers, and fear was associated with never testing among gay-identified individuals.
HIV testing rates were low among AGBM. Several modifiable barriers emerged, especially a lack of knowledge about the closest testing site. Interventions and programs that target high school-age adolescents could address external barriers by introducing HIV testing services into high schools.
青少年男同性恋者和双性恋者(AGBM)受人类免疫缺陷病毒(HIV)的影响尤为严重,但对于18岁及以下男性的检测率以及他们在考虑进行HIV检测时所面临的障碍知之甚少。因此,我们在此调查了一个多样化的全国性AGBM样本的检测行为和障碍。
通过Facebook广告招募了总共302名年龄在14 - 18岁的AGBM,以参与一项移动健康(基于短信)的HIV预防项目。招募进行了分层,以确保约50%的人没有性经验。
只有30%的性活跃参与者曾接受过HIV检测,其中近一半(42.9%)不知道去哪里进行HIV检测。基于探索性因素分析,评估HIV检测潜在障碍的九个问题被归纳为三个子量表:外部因素、恐惧和无敌感。在性活跃参与者中,从未接受过HIV检测的人在外部因素子量表(优势比,1.63;95%置信区间,1.01 - 2.66)和恐惧子量表(优势比,1.88;95%置信区间,1.11 - 3.19)上的得分显著更高。年龄较大(16 - 18岁)的青少年尤其容易受到外部因素障碍的影响,并且恐惧与男同性恋身份的人从未进行检测有关。
AGBM中的HIV检测率较低。出现了几个可改变的障碍,尤其是对最近检测地点缺乏了解。针对高中年龄青少年的干预措施和项目可以通过在高中引入HIV检测服务来解决外部障碍。
