'Less Education' Associated with PrEP and PEP Use: Only One in Five Gay Men Yet Aware of PrEP

A survey (Mansergh) of 454 HIV-negative gay men in four US cities (New York, Los Angeles, Chicago and San Francisco) has found that men with lower educational attainment (high school only) were more likely to use antiretrovirals informally for HIV prevention, either as pre-exposure prophylaxis (PrEP) or post-exposure prophylaxis (PEP), than men who had had further education.

In a parallel survey of 557 HIV-positive gay men, men with lower educational attainment were, similarly, more likely to share their antiretroviral pills with HIV-negative partners to use as PrEP or PEP.

Taken together, 22% of the men in the two surveys were under 30, 35% in their 30s and 43% 40 or over. A third were black, 38% white and the rest Hispanic or of other ethnicity.

Roughly a third each of the sample had education only to high school level, to some college qualification, or to a university degree.

The survey asked both groups if they had used PrEP or PEP or, in the case of the HIV-positive men, provided it to others, in the last six months.

Informal use of PrEP or PEP was still comparatively uncommon; only a few per cent of those surveyed overall had used ARVs as prevention or provided them in the previous six mnoths.

However men with high-school-only education were two to six times more likely to report using one of these strategies.

In the negative group, 5% of men with only high school education had used PrEP compared with 1% of others, and 8% had used PEP compared with 3% of others.

In the positive group, 6% of men with only high school education had provided PrEP compared with 1% of others and 8% had provided PEP compared with 2%. Men in their 30s and black men were also more likely to provide ARVs to partners for use as PrEP or PEP than other groups.

In multivariate analysis, lower educational level remained statistically significant in the case of PEP, but not with PrEP. HIV-negative men with high-school-only education were 3.5 times more likely to use PEP than others. HIV-positive men with high school-only education were 2.7 times more likely to provide PEP than men with some college education and 9.3 times more likely to provide it than men with university degrees.

This is a survey of informal (non-prescribed) use of ARVs as prevention and, while some of the PrEP/PEP use may reflect difficulties with safer sex, in may also reflect two other things: firstly, gay men and especially black gay men with lower socioeconomic status are more likely to have HIV and may therefore encounter partners with HIV more often or judge themselves to be at higher risk; and secondly gay men with better educations may be better at getting healthcare providers to prescribe PEP or PrEP.

Nonetheless, the authors say, "non-prescribed use of antiretroviral therapy for prophylaxis should be monitored".

Another survey (Al-Tayyib) of gay men in Denver found that only one in five gay men there had heard of PrEP.

This survey was part of the annual National HIV Behavioral Survey (NHBS) which asks gay men, injecting drug users and high-risk heterosexual people about their sexual risk behavior over the last year.

In the Denver survey of gay men, 462 men participated. Two-thirds were white, 27% Hispanic and 9% black or of other ethnicity. Forty-three per cent had had more than four partners in the past year and 17% more than ten.

The survey told participants: "In PrEP, people take a pill every day that contains the same medicine used to treat people with HIV. Scientists want to know if taking this medicine will prevent people exposed to HIV from becoming infected." Participants were asked if they were aware of this.

Only 22% of gay men had heard of PrEP. However, when it was described to them, nearly 60% said they would take PrEP if it was 75% effective and 44% said they would take it if it was only 50% effective.

Reasons for not considering PrEP (people could give more than one reason) included low perceived risk (48%); worry it would be expensive (48%); always using condoms (45%); worry they might forget to take it (38%); distrust of the scientists (17%); and worry about what others would think (10%).

More than 90% of the men said they didn't foresee changing the number of partners they had if they took PrEP, and 82% said it wouldn't change their use of condoms; 10% said they would use condoms less but 6% said they would use them more.

Presenter Alia Al-Tayyib told the Tenth AIDS Impact conference: “Understanding the attitudes and preferences of persons at risk for HIV infection is needed to help guide the development of prevention strategies that incorporate PrEP use.”
