PrEP Interest Among Men Who Have Sex with Men in the Netherlands: Covariates and Differences Across Samples.

ABSTRACT: Despite increased availability of pre-exposure prophylaxis (PrEP), PrEP uptake has remained low. To promote uptake, factors related to PrEP interest among relevant target populations warrant investigation. The aim of this study was to provide an analysis of PrEP interest among men who have sex with men (MSM) in the Netherlands, while taking study recruitment strategies into account. We recruited 154 MSM from an LGBT research panel (AmsterdamPinkPanel) and 272 MSM from convenience sampling. Both samples were part of the Flash! PrEP in Europe Survey and were compared on their PrEP interest, usage intentions, and sexual behavior. We conducted logistic regression analyses to discover variables associated with PrEP interest and intentions. Participants from the AmsterdamPinkPanel were less likely to use PrEP, had less knowledge of PrEP, and were less interested in PrEP than participants from convenience sampling. Significant covariates of PrEP interest were being single, more prior PrEP knowledge, sexual risk behaviors, such as not having used a condom during last sex and having ever used drugs in a sexual context, and not participating in the AmsterdamPinkPanel. Adding the recruitment strategy to the regression increased explained variance on top of predictors already described in the literature. Increased sexual risk behavior is related to increased PrEP interest and it helps to identify PrEP target groups. Recruitment strategies have a substantial impact on findings regarding PrEP interest and usage intentions. This study emphasizes the importance of using multiple strategies for recruiting participants to obtain a more comprehensive view of MSM's attitudes toward PrEP.

Project description:BackgroundOptimising HIV pre-exposure prophylaxis (PrEP) provision requires insight into preferences of PrEP regimens and PrEP discontinuation. We assessed regimen switching and discontinuation and their determinants among men who have sex with men (MSM) participating in the Amsterdam PrEP demonstration project.MethodsBetween 3-August-2015 and 31-May-2016, we enrolled MSM (n = 374) and TGP (n = 2) in a prospective, longitudinal study. Participants could choose between daily or event-driven PrEP regimens at enrolment and every 3 months. We assessed transition intensities (TI) and determinants of switching (i) between regimens, and (ii) from either regimen to discontinuing PrEP using a multi-state Markov model. PrEP discontinuation was defined as formally stopping study participation or having no study visit for ≥6 months.FindingsOf 367 analysed participants, 73·3% chose daily and 26·7% event-driven PrEP at enrolment. Median follow-up was 3·1 years (IQR 2·9-3·2). 121 participants switched their PrEP regimen at least once (cumulative probability 34·2%, 95% CI 29·4-39·6), with 90 switches from event-driven to daily PrEP (TI 0·35/PY, 95% CI 0·29-0·44) and 113 switches from daily to event-driven PrEP (TI 0·16/PY, 95% CI 0·13-0·20). Switching from event-driven to daily PrEP was associated with younger age, not reporting sex with HIV-positive partners, chemsex, and sexual compulsivity. Switching from daily to event-driven PrEP were associated with younger age and lower sexual satisfaction. 67 participants discontinued PrEP (cumulative probability 17·7%, 95% CI 14·1-22·2), with no difference between regimens: event-driven (n = 23, TI 0·08/PY, 95% CI 0·05-0·13) and daily PrEP (n = 44, TI 0·06/PY, 95% CI 0·04-0·08). Discontinuing daily PrEP was associated with younger age, fewer casual partners, and higher number of condomless anal sex acts with casual partners.InterpretationSwitching between PrEP regimens was common, while going from event-driven to daily PrEP use was associated with certain sexual-related determinants (i.e. chemsex, sexual compulsivity, no known HIV-positive partners). PrEP discontinuation rates were low and independent of regimens. PrEP care should consider the reasons for choice and switch of regimen and involve education on safely switching or discontinuing PrEP, especially among younger MSM.FundingZonMw, H-TEAM, RIVM, GGD research funds, Aidsfonds, Amsterdam Diner Foundation, Gilead Sciences, Gilead Sciences Europe Ltd, Janssen Pharmaceuticals, MAC AIDS Fund, ViiV Healthcare.

Project description:There are still important gaps in our understanding of how people will incorporate PrEP into their existing HIV prevention strategies. In this paper, we explore how PrEP use impacted existing sexual risk behaviours and risk reduction strategies using qualitative data from the PROUD study. From February 2014 to January 2016, we conducted 41 in-depth interviews with gay, bisexual and other men who have sex with men (GBMSM) enrolled in the PROUD PrEP study at sexual health clinics in England. The interviews were conducted in English and were audio-recorded. The recordings were transcribed, coded and analysed using framework analysis. In the interviews, we explored participants' sexual behaviour before joining the study and among those using or who had used PrEP, changes to sexual behaviour after starting PrEP. Participants described the risk behaviour and management strategies before using PrEP, which included irregular condom use, sero-sorting, and strategic positioning. Participants described their sexual risk taking before initiating PrEP in the context of the sexualised use of drugs, geographical spaces linked with higher risk sexual norms, and digitised sexual networking, as well as problematic psychological factors that exacerbated risk taking. The findings highlight that in the main, individuals who were already having frequent condomless sex, added PrEP to the existing range of risk management strategies, influencing the boundaries of the 'rules' for some but not all. While approximately half the participants reduced other risk reduction strategies after starting PrEP, the other half did not alter their behaviours. PrEP provided an additional HIV prevention option to a cohort of GBMSM at high risk of HIV due to inconsistent use of other prevention options. In summary, PrEP provides a critical and necessary additional HIV prevention option that individuals can add to existing strategies in order to enhance protection, at least from HIV. As a daily pill, PrEP offers protection in the context of the sex cultures associated with sexualised drug use, digitised sexual applications and shifting social norms around sexual fulfilment and risk taking. PrEP can offer short or longer-term options for individuals as their sexual desires change over their life course offering protection from HIV during periods of heightened risk. PrEP should not be perceived or positioned in opposition to the existing HIV prevention toolkit, but rather as additive and as a tool that can and is having a substantial impact on HIV.

Project description:IntroductionEvent-driven pre-exposure prophylaxis (edPrEP) with oral tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC) is highly effective for preventing HIV acquisition in men who have sex with men (MSM) and is preferred over daily PrEP by some MSM. However, it is largely unknown how well MSM adhere to edPrEP. We then aimed to assess PrEP protection during CAS among MSM using edPrEP and participating in the Amsterdam PrEP demonstration project (AMPrEP).MethodsWe analysed data from participants enrolled in AMPrEP who were taking edPrEP. We measured adherence through (1) a mobile application in which sexual behaviour and PrEP-use were recorded daily, (2) three-monthly self-completed questionnaires and (3) dried blood spot (DBS) samples collected around six, twelve and twenty-four months after PrEP initiation. We assessed the proportion of days with condomless anal sex (CAS) acts that were protected by PrEP, per partner type (i.e. steady partners, known casual partners, unknown casual partners), and the proportion of three-month periods during which PrEP was correctly used. Intracellular TFV-diphosphate (TFV-DP) concentrations were determined from DBS. Good adherence was defined as at least one tablet before and one tablet within 48 hours after a CAS act.ResultsBetween 11 September 2015 and 6 October 2019, 182 of 376 MSM (48.4%) used edPrEP for at least one three-month period. Of the 8224 CAS days that were reported in the app during edPrEP-use, we observed good protection for most CAS days involving steady partners (n = 1625/2455, 66.9%), known casual partners (n = 3216/3472, 92.6%) and unknown casual partners (n = 2074/2297, 90.3%). Men reported consistently correct PrEP-use in 851 (81.4%) of the 1046 three-month periods of edPrEP-use. The median TFV-DP concentration was 591 fmol/sample (interquartile range = 270 to 896).ConclusionsAdherence to edPrEP was high as determined from the online app and questionnaire. DBS measurements were consistent with two to three tablets per week on average.
