Pre-Exposure Prophylaxis Uptake and Associated Factors Among Key Populations in the Nylon and New Bell Health Districts, Cameroon
This study found that only 28.2% of eligible key populations in Cameroon's Nylon and New Bell districts initiated PrEP, with higher income and MSM status positively influencing uptake, while condomless sex, higher education, and sex as income sources negatively impacted PrEP use, highlighting the need for targeted interventions.
Background Pre-Exposure Prophylaxis (PrEP) is an effective HIV prevention strategy for populations at high risk, including men who have Sex with men (MSM) and Female Sex Workers (FSW). Despite being a proven HIV prevention tool and its effectiveness, the uptake of PrEP remains low in many settings, including Cameroon, posing challenges to HIV control. This study assessed PrEP uptake and associated factors among key populations in Nylon and New Bell Health Districts of Cameroon. Methods A cross-sectional study was conducted among 284 participants (91 MSM and 193 FSW) between January and June 2024, recruited through purposive and snowball sampling. PrEP eligibility was assessed based on self-reported risk behaviors, as outlined in World Health Organization (WHO) guidelines. Data on demographic characteristics, PrEP awareness, and uptake were collected through structured questionnaires. Logistic regression analyses identified factors associated with PrEP uptake. Results Among the 220 participants eligible for PrEP, only 62 (28.2%) accepted and were initiated on the medication. Significant predictors of uptake included monthly income above 100,000 FCFA (aOR = 4.37, 95% CI: 1.76–11.5, p = 0.002), MSM status (aOR = 2.97, 95% CI: 1.24–7.30, p = 0.015). Conversely, engaging in condomless sex (aOR = 0.35, 95% CI: 0.15–0.75, p = 0.009), higher education (aOR = 0.36, 95% CI: 0.13–0.92, p = 0.034), and relying on sex as the primary source of income (OR = 0.10, 95% CI: 0.02–0.37, p < 0.001) were negatively associated with PrEP uptake. Discussion PrEP uptake in Nylon and New Bell remains suboptimal, reflecting persistent economic, behavioral, and structural barriers. Higher income and MSM status predicted uptake, while condomless sex, sex as a source of income, and higher education were negative factors. Addressing stigma, financial vulnerability, and risk perception through tailored, community-based interventions is essential to strengthen PrEP utilization and HIV prevention outcomes in Cameroon. Conclusion PrEP uptake remains suboptimal among key populations in the Nylon and New Bell Health Districts. Financial barriers, socio-demographic factors, and sexual behavior have a significant influence on uptake. Tailored public health interventions addressing these barriers are essential for enhancing PrEP utilization and reducing HIV transmission in these vulnerable groups.

Oral pre-exposure prophylaxis (PrEP) is a critical intervention for HIV prevention among key populations (KP) in Nigeria. However, little is known about its coverage among adolescent and young key populations (AYKP). Using the 2020 Integrated Biological & Behavioural Surveillance Survey conducted among KP, including female sex workers (FSW), men who have sex with men (MSM), people who inject drugs (PWID), and transgender people (TG), we assessed the awareness and uptake of PrEP among AYKP (15-24 years) in Nigeria. We performed weighted descriptive statistics and logistic regression analyses. Of the 6882 AYKP included in this study, 36.1% were aware of PrEP, ranging from 47.9% in MSM to 19.8% in FSW. Compared with FSW, MSM (aOR = 3.7, 95%CI = 3.22–4.35) and TG (aOR = 2.6, 95%CI = 2.18–2.98) had significant higher odds of PrEP awareness. Among those aware of PrEP, 24.5% had ever taken PrEP. The uptake of PrEP varied by KP group: TG (28.1%), MSM (25.3%), PWID (18.0%), and FSW (14.4%). MSM (aOR = 2.6, 95%CI = 1.72–4.07) and TG (aOR = 2.7, 95%CI = 1.71–4.14) had significant higher odds of PrEP uptake relative to FSW. The awareness and uptake of PrEP among AYKP in Nigeria is low. This calls for more awareness creation about PrEP addressing the barriers that limit its uptake.

Clinical trial data have shown that oral pre-exposure prophylaxis (PrEP) is efficacious when taken as prescribed; however, PrEP adherence is complex and must be understood within the context of variable risk for HIV infection and use of other HIV prevention methods. Different levels of adherence may be needed in different populations to achieve HIV prevention, and the optimal methods for achieving the necessary adherence for both individual and public health benefits are unknown. Guidance for PrEP use must consider these questions to determine the success of PrEP-based HIV prevention programs. In this article, we propose a new paradigm for understanding and measuring PrEP adherence, termed prevention-effective adherence, which incorporates dynamic HIV acquisition risk behaviors and the use of HIV alternative prevention strategies. We discuss the need for daily PrEP use only during periods of risk for HIV exposure, describe key issues for measuring and understanding relevant behaviors, review lessons from another health prevention field (i.e., family planning), and provide guidance for prevention-effective PrEP use. Moreover, we challenge emerging calls for sustained, near perfect PrEP adherence regardless of risk exposure and offer a more practical and public health-focused vision for this prevention intervention.

Pre-exposure prophylaxis (PrEP) is a key strategy for HIV prevention in Thailand. National PrEP policy (2021) identifies priority populations; however, sex workers are not included, despite meeting established criteria for populations at substantial risk of HIV infection. PrEP uptake coverage among sex workers is very low - >7.5% coverage of all sex workers - and especially low among female sex workers. This study investigates key characteristics of PrEP non-users;that is, someone who has never initiated PrEP, among female, male and transgender sex workers to inform more inclusive and impactful PrEP policy and programming. A cross-sectional study was conducted from September to December2023 across seven high-HIV burden provinces (Bangkok, Chiang Mai, Chonburi, Kanchanaburi, Phuket, Sa Kaeo and Udonthani). We surveyed 1511 Thai female, male and transgender women aged ≥18years, engaged in sex work (venue-based, non-venue based and online) in the past 3months, reporting an HIV-negative or unknown HIV status. Structured questionnaires were used and data analyzed in Stata 15.1. Descriptive statistics summarized participant characteristics. Multivariate logistic regression identified factors independently associated with not using PrEP, estimating adjusted odds ratios with corresponding 95% confidence intervals. PrEP uptake was 1.3% among female sex workers (n=621), 13.9% among male sex workers (n=452) and 14.8% among transgender sex workers (n=438). The majority (83.9%) had not used PrEP (n=1268). PrEP awareness was lowest among female sex workers (27.7%). Those who had never used PrEP were significantly more likely to report PrEP concerns. Young sex workers (18-24years) and those who had recently entered sex work reported behaviors putting them at higher risk of HIV exposure. High levels of interest in using PrEP were found among PrEP non-users, which increased further when long-acting injectable PrEP was proposed. Tailored interventions to increase sex worker PrEP awareness, expanding options and addressing key concerns are needed for all sex worker populations. Specific programming is particularly needed for young, female and new entrant sex workers. Expanding PrEP options will increase PrEP demand and uptake among sex workers.

BackgroundEvidence has shown that HIV prevalence among young people, especially college students, has increased disproportionately. Preexposure prophylaxis (PrEP) and postexposure prophylaxis (PEP) are two of the most effective ways to prevent HIV, which are vital for college students with sexual experiences who have sexual risks.ObjectiveTo provide evidence for effective intervention to reduce the risk of HIV infection among young students, this study aimed to analyze the awareness and uptake of HIV PrEP and PEP among college students with sexual experiences.MethodsAn institutional-based cross-sectional study design was used to collect data through an electronic questionnaire from college students in 5 colleges located in Zhejiang Province. A total of 21,962 college students were investigated, of which 2605 students with sexual experiences were included in the data analysis with the following information collected: sociodemographic characteristics, awareness and uptake of HIV PrEP and PEP, sexual behaviors, and HIV tests. Binary logistic regression analysis was used to explore the factors on seeking PrEP and PEP.ResultsThe average age of college students with sexual experiences was 21.25 (SD 2.75) years. Overall, 61.4% (n=1600) of the participants were aware of PrEP, and 53.0% (n=1380) of them were aware of PEP. Moreover, 5.6% (n=146) of them have sought PrEP or/and PEP, and 89.1% (n=2321) have not sought PrEP or PEP. College students who had more than 6 sexual partners, have always had unprotected sex, have subjective perceived risk behavior, and undergo HIV testing were more likely to seek PrEP or/and PEP. The main ways for the participants to learn PrEP and PEP were through school clubs, the internet, and the Centers for Disease Control and Prevention. Moreover, senior students and those who had not undergone an HIV test had a lower likelihood of seeking PrEP and PEP. College students who did not have risky sexual behaviors (odds ratio 0.468, P=.004) and homosexual students (odds ratio 0.318, P=.03) were more likely not to seek PEP.ConclusionsCollege students with sexual experiences rarely seek PrEP and PEP, with a relatively low awareness of PrEP and PEP. It is very important to increase the knowledge and uptake of PrEP and PEP by educational and behavioral interventions among young students at risk for HIV infection.

Optimizing uptake of pre-exposure prophylaxis (PrEP) for individuals at risk of HIV acquisition has been challenging despite clear scientific evidence and normative guidelines, particularly for key populations (KPs) such as men who have sex with men (MSM), female sex workers (FSWs), transgender (TG) people and persons who inject drugs (PWID). Applying an iterative Programme Science cycle, building on the effective programme coverage framework, we describe the approach used by the Centre for Infectious Disease Research in Zambia (CIDRZ) to scale up PrEP delivery and address inequities in PrEP access for KP in Lusaka, Zambia. In 2019, CIDRZ partnered with 10 local KP civil society organizations (CSOs) and the Ministry of Health (MOH) to offer HIV services within KP-designated community safe spaces. KP CSO partners led KP mobilization, managed safe spaces and delivered peer support; MOH organized clinicians and clinical commodities; and CIDRZ provided technical oversight. In December 2021, we introduced a community-based intervention focused on PrEP delivery in venues where KP socialize. We collected routine programme data from September 2019 to June 2023 using programme-specific tools and the national electronic health record. We estimated the before-after effects of our intervention on PrEP uptake, continuation and equity for KP using descriptive statistics and interrupted time series regression, and used mixed-effects regression to estimate marginal probabilities of PrEP continuity. Most (25,658) of the 38,307 (67.0%) Key Population Investment Fund beneficiaries were reached with HIV prevention services at community-based venues. In total, 23,527 (61.4%) received HIV testing services, with 15,508 (65.9%) testing HIV negative and found PrEP eligible, and 15,241 (98.3%) initiating PrEP. Across all programme quarters and KP types, PrEP uptake was >90%. After introducing venue-based PrEP delivery, PrEP uptake (98.7% after vs. 96.5% before, p<0.001) and the number of initiations (p=0.014) increased significantly. The proportion of KP with ≥1 PrEP continuation visit within 6 months of initiation was unchanged post-intervention (46.7%, 95% confidence interval [CI]: 45.7%, 47.6%) versus pre-intervention (47.2%, 95% CI: 45.4%, 49.1%). Applying Programme Science principles, we demonstrate how decentralizing HIV prevention services to KP venues and safe spaces in partnership with KP CSOs enabled successful community-based PrEP delivery beyond the reach of traditional facility-based services.

Introduction: Pre-exposure prophylaxis (PrEP) is provided free of costs to at-risk populations in Kenya, including men who have sex with men (MSM), but anal intercourse is not an eligibility criterion. We set out to determine PrEP eligibility, uptake and predictors of PrEP uptake among MSM enrolled in an HIV-1 vaccine feasibility cohort in coastal Kenya. Methods: We compared the number of MSM identified as eligible for PrEP from June-December 2017 by Kenyan Ministry of Health (MoH) criteria, which do not include reported anal intercourse, to those identified as eligible by a published MSM cohort-derived HIV-1 risk score (CDHRS). We determined PrEP uptake and assessed factors associated with uptake at first offer among eligible MSM followed up monthly. Results: Out of 167 MSM assessed for PrEP eligibility, 118 (70.7%) were identified by both MoH and CDHRS eligibility criteria; 33 (19.8%) by CDHRS alone, 11 (6.6%) by MoH criteria alone, and 5 (3.0%) by neither criterion. Of the men identified by CDHRS alone, the majority (24 or 72.7%) reported receptive anal intercourse (RAI). Of the 162 MSM eligible for PrEP, 113 (69.7%) accepted PrEP at first offer. Acceptance of PrEP was higher for men reporting RAI (adjusted prevalence ratio [aPR], 1.4; 95% confidence interval [CI], 1.0-1.9), having paid for sex (aPR, 1.3; 95% CI, 1.1-1.6) and group sex (aPR, 1.4; 95% CI, 1.1-1.8), after adjustment for sociodemographic factors. Conclusions: Assessing PrEP eligibility using the CDHRS identified 20% more at-risk MSM for PrEP initiation than when Kenyan MoH criteria were used. Approximately 70% of eligible men accepted PrEP at first offer, suggesting that PrEP is acceptable among at-risk MSM. MSM reporting RAI, group sex, or paying for sex were more likely to accept PrEP. Incorporating RAI into MoH PrEP eligibility criteria would enhance the impact of PrEP programming in Kenya.

This study investigated the awareness, willingness, and practice of HIV Pre-Exposure Prophylaxis (PrEP) among female sex workers (FSWs) in Uyo, Akwa Ibom State, Nigeria. Conducted between June and August 2020, the cross-sectional research engaged 344 HIV-negative FSWs attending services at Uyo's One-Stop Shop for key populations services. Through a semi-structured questionnaire, data were collected on awareness, willingness, and practice of PrEP, and subsequently analyzed using statistical methods. The study's participants had a mean age of 29.06±5.20 years, with 68.6% falling between 25-34 years old. Notably, 76.5% were adequately aware of PrEP, while 8.1% expressed willingness to use it, and 42.4% had practiced PrEP. Factors like age, marital status, and years engaged in sex work were found to significantly influence awareness of PrEP. Participants aged 25-34 years, those previously married, and those with fewer years in sex work exhibited greater PrEP awareness. The frequency of first-time and boyfriend clients per week impacted willingness and practice of PrEP, with the former positively influencing willingness and the latter negatively affecting practice. Engaging in unprotected sex was also found to negatively correlate with PrEP practice. These findings highlight that while awareness of PrEP is relatively high among FSWs, willingness to use and actual practice of PrEP remain low. The study underscores the importance of tailored health education programs targeting FSWs, to enhance awareness and encourage adoption of effective HIV preventive measures. By addressing factors like age, marital status, and specific aspects of sex work, interventions could be designed to increase PrEP utilization, thereby contributing to the reduction of HIV transmission in this population. Keywords: Female sex workers, HIV, Key Populations, One Stop Shop, Pre-exposure prophylaxis, Uyo.

We assessed the awareness, acceptance (willingness to use), and uptake of pre-exposure prophylaxis (PrEP), along with the gap between PrEP eligibility and self-perceived HIV risk among men who have sex with men (MSM) in Shaanxi Province, China in 2022. Participants completed surveys on PrEP, and were screened for HIV, syphilis, Chlamydia trachomatis, and Neisseria gonorrhoeae. PrEP eligibility was determined using Chinese PrEP guidelines, and participants' self-perceived HIV risk was documented. Multivariable logistic regression Analysed factors influencing PrEP-related outcomes And the discrepancy between perceived and actual risk. Among 1,085 participants (median age: 32 years), 54.4% resided in urban areas, 71.1% identified as homosexual, And 60.8% held a college degree or higher. Although 87.0% were PrEP-eligible, only 28.5% were identified as high risk. PrEP awareness was 82.0%, yet only 8.8% had used it, And 3.3% currently used it. Despite 72.9% expressing willingness, uptake was hindered by high costs. Rural residence and lower education correlated with reduced awareness and acceptance, while greater income, more male partners, and recent STI testing predicted higher acceptance. Prior PEP use was strongly associated with PrEP use. Targeted efforts to improve affordability, accessibility, and education are crucial for better prevention results.

Despite theincreasing availability of prevention tools like pre-exposure prophylaxis (PrEP), HIV incidence remains disproportionately high in sub-Saharan Africa. We examined PrEP awareness, uptake and persistence among participants enrolling into an HIV incidence cohort in Kenya. We used cross-sectional enrolment data from the Multinational Observational Cohort of HIV and other Infections (MOCHI) in Homa Bay and Kericho, Kenya. The cohort recruited individuals aged 14-55 years with a recent history of sexually transmitted infection, transactional sex, condomless sex and/or injection drug use. Participants completed questionnaires on PrEP, demographics and sexual behaviours. We used multivariable robust Poisson regression to estimate adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs) for associations with never hearing of PrEP, never taking PrEP and ever stopping PrEP. Between 12/2021 and 5/2023, 399 participants attempted the PrEP questionnaire, of whom 316 (79.2%) were female and median age was 22 years (interquartile range 19-24); 316 of 390 participants (81.0%) engaged in sex work or transactional sex. Of 396 participants who responded to the question, 120 (30.3%) had never heard of PrEP. Of 275 participants who had heard of PrEP, 206 (74.9%) had never taken it. Of 69 participants who had ever taken PrEP, 50 (72.5%) stopped it at some time prior to enrolment. Participants aged 15-19 years more often reported never taking PrEP compared with those 25-36 years (aPR 1.31, 95% CI: 1.06-1.61). Participants who knew someone who took PrEP less often reported never hearing about PrEP (aPR 0.10, 95% CI: 0.04-0.23) and never taking PrEP (aPR: 0.69, 95% CI: 0.60-0.80). Stopping PrEP was more common among participants with a weekly household income ≤1000 versus >1000 Kenyan shillings (aPR 1.40, 95% CI: 1.02-1.93) and those using alcohol/drugs before sex (aPR 1.53, 95% CI: 1.03-2.26). Stopping PrEP was less common among those engaging in sex work or transactional sex (aPR 0.6, 95% CI: 0.40-0.92). We identified substantial gaps in PrEP awareness, uptake and persistence, which were associated with potential system- and individual-level risk factors. Our analyses also highlight the importance of increasing PrEP engagement among individuals who do not know others taking PrEP.
