“…The profile was blank, did not contain any information, and no users were messaged. Based on previous research, we expect 18% of urban users to report PrEP use [ 14 ]. If we estimate a 6% difference as clinically significant between urban and rural users, we estimated a need to sample 2100 profiles with an 80% power and a 2-tailed α of .05.…”

“…Irrespective of whether the user profile presented a face picture, a body picture, other photos (neither face nor body), or no picture (blank) were abstracted. Picture status was considered a surrogate for willingness to share , as those who share a face picture have been found to be associated with a likelihood of reporting more data about themselves, including PrEP use [ 14 , 28 ].…”

“…Lack of pictures, minimal bios, grammatically incorrect bios, or lack of linked social media accounts are viewed as less trustworthy [ 13 ]. In a nationwide survey of urban Grindr profiles, 18.1% of users reported PrEP use, and 61% reported their HIV status [ 14 ]. PrEP disclosure was 40% less common among Black users than among White users and 30% less common among users in the southern United States than in the northeastern United States [ 14 ].…”

These disparities in PrEP disclosures on GSN apps mirror those reported by the Centers for Disease Control and Prevention (CDC) and, as such, may provide a real-world avenue for epidemiological surveillance.…”

Background Geosocial networking (GSN) apps play a pivotal role in catalyzing sexual partnering, especially among men who have sex with men. Objective To quantify the prevalence and disparities in disclosure of pre-exposure prophylaxis (PrEP) use and COVID-19 vaccination among GSN app users, mostly men who have sex with men, in the United States. Methods Web-based Grindr profiles from the top 50 metropolitan areas as well as the 50 most rural counties in the United States by population were randomly sampled. Grindr provides an option to disclose current PrEP use (HIV positive, HIV negative, or HIV negative with PrEP use). The free text in all profiles was analyzed, and any mention of COVID-19 vaccination was recorded. Multivariable logistic regression to assess independent associations with PrEP disclosure and COVID-19 vaccination was performed. Imputation analyses were used to test the robustness of the results. Results We evaluated 1889 urban and 384 rural profiles. Mean age among urban profiles was 32.9 (SD 9.6) years; mean age among rural profiles was 33.5 (SD 12.1) years (P=.41). Among the urban profiles, 16% reported being vaccinated against COVID-19 and 23% reported PrEP use compared to 10% and 8% in rural profiles, respectively (P=.002 and P<.001, respectively). Reporting COVID-19 vaccination (adjusted odds ratio [aOR] 1.7, 95% CI 1.2-2.4), living in an urban center (aOR 3.2, 95% CI 1.8-5.7), and showing a face picture as part of the Grindr profile (aOR 4.0, 95% CI 2.3-7.0) were positively associated with PrEP disclosure. Self-identified Black and Latino users were less likely to report PrEP use (aOR 0.6, 95% CI 0.4-0.9 and aOR 0.5, 95% CI 0.4-0.9, respectively). Reporting PrEP use (aOR 1.7, 95% CI 1.2-2.4), living in an urban center (aOR 2.5, 95% CI 1.4-4.5), having a “discreet” status (aOR 1.6, 95% CI 1.0-2.5), and showing a face picture (aOR 2.7, 95% CI 1.5-4.8) were positively associated with reporting COVID-19 vaccination on their profile. Users in the southern United States were less likely to report COVID-19 vaccination status than those in the northeast United States (aOR 0.6, 95% CI 0.3-0.9). Conclusions Variations in PrEP disclosure are associated with race, whereas COVID-19 vaccination disclosure is associated with geographic area. However, rural GSN users were less likely to report both PrEP use and COVID-19 vaccination. The data demonstrate a need to expand health preventative services in the rural United States for sexual minorities. GSN platforms may be ideal for deployment of preventative interventions to improve access for this difficult-to-reach population.

“…Understanding the current levels of knowledge and the barriers to access to PEP/PrEP among this group is an important step to expand their acceptance, as the knowledge of PEP/PrEP was correlated with the future willingness to adopt it (Petroll et al, 2017;Chu et al, 2019). Therefore, the objective of this study is to assess awareness of PEP and PrEP among Brazilian MSM.…”

AIM: We aim to characterize PEP and PrEP awareness in alarge national sample of Brazilian MSM. SUBJECT: Various disparities exist in HIV transmission among men who have sex withmen (MSM). Post-exposure Prophylaxis (PEP) and Pre-exposure prophylaxis (PrEP)has been shown as important strategies to prevent HIV, but there is variation in uptakewithin the MSM population. METHODS: This was a cross-sectional,population survey-based, analytical study, conducted exclusively online in all theregions of Brazil, with a sample of 2250 MSM. The multivariate logistic regressionmodel was adopted to produce adjusted odds ratios (ORa), considering a significancelevel at .05. RESULTS: We found a low knowledge about forms of prevention, with 54.6%claiming to know PEP and 46.4% PrEP. Men who did not recognize themselves ashomosexual, that is bisexual (ORa = 1.89, 95% CI 1.48-2.40) and heterosexual (ORa =3.83, 95% CI 2.80-5.24) were more likely to know the PEP. Having a higher minimumwage (ORa = 0.72, 95% CI 0.56-0.93) decreased the chances of knowing PrEP, aswell as having a higher level of education, factors that usually coexist, with thegraduate level being the highest of them (ORa = 0.13, 95% CI 0.06-0.28). CONCLUSION: Men still seem to know PEP from experience, after the failure of other preventivemeasures and not beforehand. PrEP awareness is permeated by barriers related tostructure and social determinants.
