Pre-exposure prophylaxis (PrEP) has been demonstrated to be an efficacious HIV prevention tool for men who have sex with men (MSM), but epidemic simulation models estimate that high levels of PrEP coverage – perhaps as high as 40%-60% of eligible MSM – might be required to reduce HIV incidence. In the United States, is no current system to provide annual estimates of PrEP awareness, willingness to use or current usage among MSM. There is a particular lack of data from MSM in non-urban areas.
Method / Issue:
We used data from two cycles of the American Men’s Internet Survey (AMIS), an annual national cross-sectional internet survey of MSM in the US. Data were collected from December 2013-April 2014 (AMIS-2013 cycle) and September 2014-April 2015 (AMIS-2014 cycle) from men aged at least 18 years who resided in the US and reported sex with another man in the 12 months before interview. Men were recruited through banner advertisements on a variety of gay-frequented websites and social networking websites/applications. Men who reported being HIV-negative were asked whether they had ever heard of taking anti-HIV medicines to prevent HIV infection (awareness), whether they would be willing to take a daily pill to reduce the risk of becoming HIV infected (willingness), and whether they had ever taken anti-HIV medications before sex to reduce their risk of becoming HIV infected (took PrEP). We calculated proportions of men with each outcome by year compared proportions of men by ed characteristics within year using chi-square tests for AMIS-2013 and calculated the prevalence ratio comparing AMIS-2014 respondents with the AMIS-2013 respondents for each outcome.
Results / Comments:
Data were obtained from 3,096 MSM in AMIS-2013, and from 3,931 men in AMIS-2014 . In AMIS-2013, 44% of men were aware of PrEP, 42% were willing to take PrEP, and 1.3% reported ever using PrEP. In AMIS-2014, 65% of men were aware of PrEP, 41% were willing to take PrEP, and 2.8% reported ever using PrEP. In AMIS-2013, PrEP willingness was higher in Black and Hispanic MSM (each 51%) than in White MSM (41%, p<0.01), but PrEP use was higher in White versus Black MSM (1.3% vs 0%, p < 0.01). In AMIS-2013, comparing men in urban and rural areas, PrEP awareness (48% vs 37%, P< 0.01) and use (1.7% vs. 0.6%, p<0.01) were higher in urban MSM than rural MSM. The AMIS-2014 compared to AMIS-2013 prevalence ratios for awareness (PR 1.48, 95% CI 1.41-1.54) and use (PR 2.1, 95% CI 1.5-3.1) indicated that the awareness and use of PrEP had increased significantly between the two periods.
In these two convenience samples of MSM, PrEP awareness and use increased in the US from 2013-2015. There is still a need to increase PrEP coverage and a need to address lower PrEP awareness in rural MSM and lower PrEP use among MSM of color.
