RESUMEN

BACKGROUND: While the COVID-19 pandemic disrupted HIV preventative services in sub-Saharan Africa, little is known about the specific impacts the pandemic has had on men who have sex with men (MSM) in Kenya. METHODS: Data were from an HIV self-testing intervention implemented in Kisumu, Mombasa and Kiambu counties in Kenya. Baseline data collection took place from May to July 2019, and endline in August-October 2020, coinciding with the lifting of some COVID-19 mitigation measures. Using endline data, this study characterised the impact the pandemic had on participants' risk behaviours, experience of violence and behaviours related to HIV. Logistic regression was used to understand factors related to changes in risk behaviours and experiences of violence; adjusted AORs (AORs) and 95% CIs are reported. RESULTS: Median age was 24 years (IQR: 21-27). Most respondents (93.9%) reported no change or a decrease in the number of sexual partners (median number of male sexual partners: 2, IQR: 2-4). Some participants reported an increase in alcohol (10%) and drug (16%) consumption, while 40% and 28% reported decreases in alcohol and drug consumption, respectively. Approximately 3% and 10% reported an increase in violence from intimate partners and police/authorities, respectively. Compared with those with primary education, those with post-secondary education were 60% less likely to report an increase in the number of male sexual partners per week (AOR: 0.4, 95% CI: 0.2 to 0.9), while those who were HIV positive were at twofold the odds of reporting an increase or sustained levels of violence from intimate partners (AOR: 2.0, 95% CI: 1.1 to 4.0). CONCLUSION: The results of this study demonstrate heterogeneity in participants' access to preventative HIV and clinical care services in Kenya after the onset of the COVID-19 epidemic. These results indicate the importance of responding to specific needs of MSM and adapting programmes during times of crisis.

RESUMEN

BACKGROUND: HIV programming in Ukraine largely targets "key population" groups. Men who purchase sex are not directly reached. The aim of our study was to explore the prevalence of sexually transmitted and blood-borne infections (STBBIs) among men who purchase sex from female sex workers. METHODS: Following geographic mapping and population size estimation at each "hotspot", we conducted a cross-sectional bio-behavioural survey with men who purchase sex between September 2017 and March 2018 in Dnipro, Ukraine. Eligibility criteria included purchasing sex services at a "hotspot" and being ≥ 18 years. Participants completed a structured questionnaire, followed by HIV/HCV rapid testing and a dried blood spot (DBS) sample collection for confirmatory serology. RESULTS: The study enrolled 370 participants. The median age was 32 (interquartile range [IQR] = 27-38) and the median age of first purchase of sexual services was 22 (IQR = 19-27). Over half (56%) of participants reported ever testing for HIV; four participants (2%, N = 206) reported having tested positive for HIV, with three out of the four reporting being on ART. Forty percent of participants had ever tested for HCV, with three (2%, N = 142) having ever tested positive for HCV. In DBS testing, nine participants (2.4%) tested positive for HIV and 24 (6.5%) tested positive for ever having an HCV infection. CONCLUSION: Prevalence of HIV and HCV in this population was high. Given high rates of study enrolment and testing, efforts should be made to reach men who purchase sex with expanded STBBI programming.

RESUMEN

Based on a diary writing exercise, this paper illuminates the complex ways in which sex workers in Ukraine actively work through and manage stigma in their daily lives. Pushing beyond the notion of stigma as a static and fixed psychosocial designation that can be readily measured, we argue that stigma is actively confronted by sex workers through various forms of gendered emotional and physical labour that enable them to recuperate a sense of moral personhood. This notion of moral personhood is often tied to wider gender-specific values pertaining to caregiving and motherhood.

RESUMEN

PURPOSE OF REVIEW: To review the impact of the COVID-19 pandemic and its public health response on key populations at risk of HIV infection, with a focus on sex workers. RECENT FINDINGS: Since last year several groups have documented how the COVID-19 pandemic has impacted the livelihoods and health of sex workers. We focus on case studies from Kenya, Ukraine, and India and place these in the broader global context of sex worker communities, drawing on common themes that span geographies. COVID-19-associated lockdowns have significantly disrupted sex work, leading to economic and health challenges for sex workers, ranging from HIV-related services to mental health and exposure to violence. Several adaptations have been undertaken by sex workers and frontline workers, including migration, a move to mobile services, and struggling to find economic supports. Strengthening community-based responses for future pandemics and other shocks is critical to safeguard the health of marginalized populations.

RESUMEN

BACKGROUND: Previous studies have shown substantial differences in geographic clustering of sexually transmitted infections (STI), such as chlamydia (CT) and gonorrhea (NG), conditional on epidemic phase. Chlamydia and NG have recently shown resurgent epidemiology in the northern hemisphere. This study describes the recent epidemiology of CT and NG in Winnipeg, Canada, combining traditional surveillance tools with place-based analyses, and comparing the ecological niches of CT and NG, in the context of their evolving epidemiology. METHODS: Data were collected as part of routine public health surveillance between 2007 and 2016. Secular trends for CT and NG, and CT/NG coinfection were examined. Gini coefficients and population attributable fractions explored the distribution, and concentration of infections over time and space. RESULTS: Rates of CT increased from 394.9/100,000 population to 476.2/100,000 population from 2007 to 2016. Gonorrhea rates increased from 78.0/100,000 population to 143.5/100,000 population during the same period. Each pathogen had its own ecological niche: CT was widespread geographically and socio-demographically, while NG was clustered in Winnipeg's inner-core. CT/NG co-infections had the narrowest space and age distribution. NG was shown to be undergoing a growth phase, with clear signs of geographic dispersion. The expansion of NG resembled the geographic distribution of CT. CONCLUSIONS: We demonstrated that NG was experiencing a growth phase, confirming theoretical predictions of geographic dispersion during a growth phase. During this phase, NG occupied similar geographic spaces as CT. Knowledge of different ecological niches could lead to better targeting of resources for subpopulations vulnerable to STIs.

RESUMEN

BACKGROUND: Manitoba is a central Canadian province with annual rates of new HIV infections consistently higher than the Canadian average. National surveillance statistics and data from the provincial HIV care program suggest that epidemiological heterogeneity exists across Manitoba. New HIV cases are disproportionately reported among females, Indigenous-identifying individuals, and those with a history of injection drug use. Given the heterogeneity in acquisition, it is of interest to understand whether this translates into inequalities in HIV care across Manitoba. METHODS: A sample of 703 participants from a clinical cohort of people living with HIV in Manitoba, with data current to the end of 2017, was used to conduct cross-sectional, disaggregated analyses of the HIV care cascade to identify heterogeneity in service coverage and clinical outcomes among different groups receiving HIV care in Manitoba. Equiplots are used to identify and visualize inequalities across the cascade. Exploratory multivariable logistic regression models quantify associations between equity variables (age, sex, geography, ethnicity, immigration status, exposure category) and progression along the cascade. Adjusted odds ratios (AOR) and 95% confidence intervals (95%CI) are reported. RESULTS: Equity analyses highlight inequalities in engagement in and coverage of HIV-related health services among cohort participants. Equiplots illustrate that the proportion of participants in each cascade step is greater for those who are older, white, non-immigrants, and report no history of injection drug use. Compared to those living in Winnipeg, participants in eastern Manitoba have greater odds of achieving virologic suppression (AOR[95%CI] = 3.8[1.3-11.2]). The odds of Indigenous participants being virologically suppressed is half that of white participants (AOR[95%CI] = 0.5[0.3-0.7]), whereas African/Caribbean/Black participants are significantly less likely than white participants to be in care and retained in care (AOR[95%CI] = 0.3[0.2-0.7] and 0.4[0.2-0.9], respectively). CONCLUSIONS: Inequalities exist across the cascade for different groups of Manitobans living with HIV; equiplots are an innovative method for visualizing these inequalities. Alongside future research aiming to understand why inequalities exist across the cascade in Manitoba, our equity analyses can generate hypotheses and provide evidence to inform patient-centred care plans that meet the needs of diverse client subgroups and advocate for policy changes that facilitate more equitable HIV care across the province.

RESUMEN

BACKGROUND: Across Sub-Saharan Africa, young women who sell sex (YSW) face institutional barriers in accessing sexual health and HIV prevention programs designed for female sex workers. In 2018, Kenya developed a national framework to guide service provision for YSW aged 14-24 years. To help inform the implementation of the framework, we estimated the burden of vulnerabilities related to the Sustainable Development Goals (SDGs related to health and gender equality) and program contact among YSW. METHODS: We used data from Transitions, a 2015 bio-behavioural cross-sectional survey of 408 YSW aged 14-24 years in Mombasa, Kenya. We estimated the prevalence of sexual (inconsistent condom use), structural (financial, violence), and reproductive health vulnerabilities; and characterized engagement with local HIV programs tailored to sex workers. We then compared the prevalence of vulnerabilities by age group (14-18 years, N = 117; 19-24 years, N = 291) and by program contact (ever contacted by local program for sex workers). RESULTS: 47.3% reported inconsistent condom use with any partner in the previous week (no difference by age-group, p = 1.00). Structural vulnerabilities were common and did not vary by age: 83.6% did not have a regular source of income; 29.9 and 29.2% had experienced physical and sexual violence, respectively. 26.5% reported at least one pregnancy before age 18, and 18.5% used a non-reliable form of contraception with little variability by age. 25.7% were aware of at least one program, and only 13.7% of YSW had ever been contacted by a program (8.5% of those aged 14-18 years; and 15.8% of those aged 19-24 years, p = 0.06). Sexual, structural, and reproductive health vulnerabilities did not vary by program contact. CONCLUSIONS: SDG-related vulnerabilities begin early in the lives of YSW who are not currently reached by programs designed for female sex workers.

RESUMEN

OBJECTIVES: Ukraine has one of the largest HIV epidemics in Europe, with high prevalence among female sex workers (FSWs). We aimed to identify factors associated with HIV testing and receipt of the test result in the last 12 months, HIV prevalence and self-reported positive status among FSWs in Ukraine. METHODS: We used data from an Integrated Bio-Behavioural Survey among FSWs conducted in 2013-2014. The survey methodology combined three sampling strategies: time and location sampling, respondent-driven sampling and key informant recruitment. We used multivariable regression to identify factors associated with self-reported HIV testing in the last 12 months, HIV prevalence and self-reported positive status among FSWs living with HIV. Explored factors included: age, age at first sex, age at entry into sex work, education, marital status, employment status beside sex work, condom use with last paying or non-paying sexual partner, drug or alcohol consumption and sex work venue. RESULTS: Recent HIV testing was low overall with only 63.2% of FSWs reported having tested and received their test result in the last 12 months prior to the survey. HIV prevalence was 7.1% overall, but only 45.0% of FSWs living with HIV were aware of their HIV status. Testing in the last 12 months with receipt of test result was less common among FSWs who used drugs ever in life (adjusted OR (AOR) 0.7, 95% CI 0.6 to 0.9), women soliciting clients indoors (AOR 0.8, 95% CI 0.7 to 0.9) and those not using a condom with last paying sexual partner (AOR 0.3, 95% CI 0.2 to 0.5). HIV positivity was associated with history of ever using drugs (AOR 2.3, 95% CI 1.4 to 3.6) and soliciting clients outdoors (AOR 1.5, 95% CI 1.1 to 2.0). Women working indoors were less aware of their positive status (AOR 0.1, 95% CI 0.1 to 0.9). CONCLUSION: HIV prevalence is high among FSWs in Ukraine, and testing and knowledge of one's status remain insufficient. HIV testing programmes need to expand with strategies to reach specific subgroups of FSWs.

RESUMEN

OBJECTIVES: In 2013, Kenya's National AIDS and STI Control Programme established a Learning Site (LS) in Mombasa County to support and strengthen capacity for HIV prevention programming within organisations working with sex workers. A defining feature of LS was the use of a Programme Science approach throughout its development and implementation. We provide an overview of the key components of LS, present findings from 23 months of programme monitoring data, and highlight key Programme Science lessons from its implementation and monitoring. METHODS: Routine monitoring data collected from September 2013 through July 2015 are presented. Individual-level service utilisation data were collected monthly and indicators of interest were analysed over time to illustrate trends in enrolment, programme coverage and service utilisation among sex workers in Mombasa County. RESULTS: Over the monitoring period, outreach programme enrolment occurred rapidly; condom distribution targets were met consistently; rates of STI screening remained high and diagnoses declined; and reporting of and response to violent incidents increased. At the same time, enrolment in LS clinics was relatively low among female sex workers, and HIV testing at LS was low among both female and male sex workers. CONCLUSION: Lessons learnt from operationalising the Programme Science framework through the Mombasa LS can inform the development and implementation of similar LS in different geographical and epidemiological contexts. Importantly, meaningful involvement of sex workers in the design, implementation and monitoring processes ensures that overall programme performance is optimised in the context of local, 'on-the-ground' realities. Additionally, learnings from LS highlight the importance of introducing enhanced monitoring and evaluations systems into complex programmes to better understand and explain programme dynamics over time.

RESUMEN

Standardized self-management supports are an integral part of care delivery for many chronic conditions. We used the validated Patient Activation Measure (PAM®) to assess level of engagement for self-management from a sample of 165 people living with HIV (PLWH) and 163 people with diabetes. We conducted multivariable logistic regression to assess associations between demographics and PAM® scores. PLWH had high levels of activation that were no different from those of people with diabetes (mean score = 67.2, SD = 14.2 versus 65.0, SD = 14.9, p = 0.183). After adjusting for patient characteristics, only being on disability compared to being employed or a student was associated with being less activated (AOR = 0.276, 95%CI = 0.103-0.742). Our findings highlight the potential for the implementation of existing standardized chronic disease self-management programs to enhance the care delivery for PLWH, with people on disability as potential target populations.

RESUMEN

Understanding patterns of serological testing for hepatitis B & C, and syphilis among HIV-positive individuals, prior to HIV diagnosis, can inform HIV diagnosis, engagement and prevention strategies. This was a population-based, retrospective analysis of prior serological testing among HIV-positive individuals in Manitoba, Canada. HIV cases were age-, sex- and region-matched to HIV-negative controls at a 1:5 ratio. Conditional logistic regression was used to examine previous serological tests and HIV status. Odds ratios (ORs) and their 95% confidence intervals (95% CI) were reported. A total of 193 cases and 965 controls were included. In the 5 years prior to diagnosis, 50% of cases had at least one test, compared to 26% of controls. Compared to those who did not have serological testing in the 5 years prior to HIV infection, those who had one serological test were at twice the odds of being HIV positive (OR: 1.9, 95% CI: 1.2-2.9), while those with 2 or more tests were at even higher odds (OR: 5.5, 95%CI: 3.7-8.4). HIV cases had higher serological testing rates. Interactions between public health and other healthcare providers should be strengthened.

RESUMEN

Evidence suggests that in India, the early stages of a woman's career as a sex worker may be an important period to target for HIV and sexually transmitted infection prevention. Before such an intervention is designed and implemented, it is necessary to first understand the life circumstances of women at the start of their sex work careers. We performed a review to bring together available literature pertaining to entry into sex work in India and to highlight knowledge gaps. We found that historical traditions of dedication into sex work, financial insecurity, family discord, violence and coercion, and desire for financial independence are commonly reported reasons for entering into sex work. We also found that families and the broader sex worker community play an important role in the early stages of a woman's sex work career. We suggest that HIV-prevention programmes in India would substantially benefit from a deeper understanding of the life circumstances of new and young women sex workers. Further research should be conducted focusing on family and community involvement in women's entry into sex work, and on the important period of time after a woman's first commercial sex encounter, but before self-identification as a sex worker.

RESUMEN

INTRODUCTION: Since the onset of the Russian invasion on 24 February 2022, the health system in Ukraine has been placed under tremendous pressure, with damage to critical infrastructure, large losses of human resources, restricted mobility and significant supply chain interruptions. Based on a longstanding partnership between the Ukrainian Institute for Social Research after Oleksandr Yaremenko (UISR after O. Yaremenko) and the Institute for Global Public Health at the University of Manitoba, we explore the impact of the full-scale war on non-governmental organizations (NGOs, including charitable organizations) providing services for key population groups in Ukraine. METHODS: We conducted in-depth qualitative interviews with key representatives from NGOs working with key population groups (i.e., people living with HIV, sex workers, men who have sex with men, people who inject drugs and transgender people) throughout Ukraine. Members of the UISR after O. Yaremenko research team recruited participants from organizations working at national, regional and local levels. The research team members conducted 26 interviews (22 with women and four with men) between 15 May and 7 June 2023. Interviews were conducted virtually in Ukrainian and interpretively analysed to draw out key themes. RESULTS: Applying Roels et al.'s notion of "first responders", our findings explore how the full-scale war personally and organizationally impacted workers at Ukrainian NGOs. Despite the impacts to participants' physical and mental health, frontline workers continued to support HIV prevention and treatment while also responding to the need for humanitarian aid among their clients and the wider community. Furthermore, despite inadequate pay and compensation for their work, frontline workers assumed additional responsibilities, thereby exceeding their normal workload during the extraordinary conditions of war. CONCLUSIONS: NGOs play a vital role as responders, adapting their services to meet the emergent needs of communities during structural shocks, such as war. There is an urgent need to support NGOs with adequate resources for key population service delivery and to increase support for their important role in humanitarian aid.

RESUMEN

Testing for human immunodeficiency virus (HIV) and hepatitis C virus (HCV) using dried blood spot (DBS) specimens has been an integral part of bio-behavioural surveillance in Canada for almost two decades, though less is known regarding the use of DBS in surveillance of other sexually transmitted and blood-borne infections (STBBI). A systematic review was conducted using a peer-reviewed search strategy to assess the current evidence regarding the validity of STBBI testing using DBS specimens. Eligibility criteria included studies reporting use of DBS specimens for STBBI testing with either commercially available or "in-house" tests in populations 15 years of age or older. Studies reporting a measure of validity such as sensitivity, specificity, positive and negative predictive values were eligible for inclusion. Quality of studies and risk of bias were assessed using the QUADAS-2 tool. A total of 7,132 records were identified. Of these, 174 met the criteria for inclusion. Among the studies that reported validity measures, a substantial proportion demonstrated high sensitivity (≥90%) in 62.5% of cases (N = 334/534 sensitivity measurements), and high specificity (≥90%) was observed in 84.9% of instances (N = 383/451 specificity measurements). However, the quality of the studies varied greatly. Our findings support the validity of the use of DBS specimens in STBBI testing where sufficient evidence was available, but validity is highly dependent on thorough method development and validation.

RESUMEN

INTRODUCTION: Measuring the coverage of HIV prevention services for key populations (KPs) has consistently been a challenge for national HIV programmes. The current frameworks and measurement methods lack emphasis on effective coverage, occur infrequently, lack timeliness and limit the participation of KPs. The Effective Programme Coverage framework, which utilizes a programme science approach, provides an opportunity to assess gaps in various coverage domains and explore the underlying reasons for these gaps, in order to develop targeted solutions. We have demonstrated the application of this framework in partnership with the KP community in Nairobi, Kenya, using an expanded Polling Booth Survey (ePBS) method. METHODS: Data were collected between April and May 2023 among female sex workers (FSWs) and men who have sex with men (MSM) using (a) PBS, (b) bio-behavioural survey and (c) focus group discussions. Data collection and analysis involved both KP community and non-community researchers. Descriptive analysis was performed, and proportions were used to assess the programme coverage gaps. The data were weighted to account for the sampling design and unequal selection probabilities. Thematic analysis was conducted on the qualitative data. RESULTS: The condom programme for FSW and MSM had low availability (60.2% and 50.9%), contact (68.8% and 65.9%) and utilization (52.1% and 43.9%) coverages. The pre-exposure prophylaxis (PrEP) programme had very low utilization coverage for FSW and MSM (4.4% and 2.8%), while antiretroviral therapy utilization coverage was higher (86.6% and 87.7%). Reasons for coverage gaps included a low peer educator-to-peer ratio, longer distance to the clinics, shortage of free condoms supplied by the government, experienced and anticipated side effects related to PrEP, and stigma and discrimination experienced in the facilities. CONCLUSIONS: The Effective Programme Coverage framework allows programmes to assess coverage gaps and develop solutions and a research agenda targeted at specific domains of coverage with large gaps. The ePBS method works well in collecting data to understand coverage gaps rapidly and allows for the engagement of the KP community.

RESUMEN

BACKGROUND: Approximately 26% of Canadians living with HIV are unaware of their status. Point-of-care (POC) HIV tests have been introduced to simplify and expand HIV testing. OBJECTIVE: To evaluate the feasibility and acceptability of POC testing in an emergency department (ED) setting in Winnipeg, Manitoba. METHODS: A cross-sectional study of unselected adults presenting to the ED at the Health Sciences Centre Hospital (Winnipeg, Manitoba) was performed. Study procedures included pre- and post-test counselling, administration of the INSTI HIV-1/HIV-2 Antibody Test (bioLytical Laboratories, Canada) and a brief questionnaire. Venous blood samples were collected from participants for confirmatory testing on all reactive and indeterminate specimens. RESULTS: In total, 501 adults participated in the study. The majority of participants were younger than 40 years of age, approximately one-half (48.5%) were women and 53% self-identified as Aboriginal. Nearly one-half (49.1%) of the participants had undergone previous HIV testing, although 63% of these tests were performed more than a year earlier. A total of seven individuals tested reactive with the POC test, all of whom were confirmed positive using serological testing (1.4%) and were linked to an HIV specialist within 24 h. Nearly all of the participants (96%) reported satisfaction with the test and believed it belonged in the ED (93%). CONCLUSIONS: Of the participants tested, 1.4% tested reactive for HIV, which is significantly higher than the reported prevalence in Manitoba and in other similar studies conducted in North America. Furthermore, all individuals were linked to timely care. The present study demonstrated that this particular busy tertiary care ED is an important and feasible location for HIV POC testing.


INTRODUCTION: Environ 26 % des Canadiens qui sont atteints du VIH ne connaissent pas leur statut. Les tests du VIH au point de service (PDS) ont créés pour simplifier et généraliser le test du VIH. OBJECTIF: Évaluer la faisabilité et l'acceptabilité du test au PDS au sein d'une urgence de Winnipeg, au Manitoba. MÉTHODOLOGIE: Les chercheurs ont procédé à une étude transversale auprès d'adultes non sélectionnés qui se sont présentés à l'urgence du Health Sciences Centre Hospital de Winnipeg, au Manitoba. Pendant l'étude, les interventions incluaient des conseils avant et après le test, l'administration du test INSTI de recherche des anticorps anti-VIH-1/VIH-2 (bioLytical Laboratories, Canada) et un bref questionnaire. Ils ont prélevé du sang veineux pour effectuer un test de confirmation sur tous les échantillons réactifs ou indéterminés. RÉSULTATS: Au total, 501 adultes ont participé à l'étude. La majorité avaient moins de 40 ans, environ la moitié (48,5 %) étaient des femmes et 53 % ont eux-mêmes précisé qu'ils étaient des Autochtones. Près de la moitié (49 %) avaient déjà subi un test du VIH, mais 63 % de ces tests avaient été exécutés plus d'un an auparavant. Au total, sept personnes étaient réactives au test au PDS, toutes confirmées comme positives au test sérologique (1,4 %) et ont été orientées vers un spécialiste du VIH dans les 24 heures. Presque tous les participants (96 %) se sont dits satisfaits du test et pensaient qu'il était caractéristique de l'urgence (93 %). CONCLUSIONS: Sur les participants qui ont subi le dépistage, 1,4 % était réactif au VIH, ce qui est considérablement plus élevé que la prévalence déclarée au Manitoba et dans d'autres études similaires d'Amérique du Nord. De plus, toutes les personnes ont été orientées rapidement vers des soins. La présente étude a démontré que cette urgence de soins tertiaires achalandée est un lieu important et faisable comme PDS pour effectuer le test du VIH.

RESUMEN

Improvements in context-specific programming are essential to address HIV and other sexually transmitted and blood-borne infection epidemics globally. A programme science approach emphasises the need for context-specific evidence and knowledge, generated on an ongoing basis, to inform timely and appropriate programmatic decisions. We aim to accelerate and improve the use of embedded research, inquiry, and learning to optimise population-level impact of public health programmes and to introduce an effective programme coverage framework as one tool to facilitate this goal. The framework was developed in partnership with public health experts in HIV and sexually transmitted and blood-borne infections through several workshops and meetings. The framework is a practice-based tool that centres on the use of data from iterative cycles of programme-embedded research and learning, as well as routine programme monitoring, to refine the strategy and implementation of a programme. This programme science approach aims to reduce programme coverage gaps, to optimise impact at the population level, and to achieve effective coverage. This framework should facilitate the generation of programme-embedded research and learning agendas to inform resource allocation, optimise population-level impact, and achieve equitable and effective programme coverage.

RESUMEN

Men who have sex with men (MSM) bear a disproportionate burden of new HIV infections in Kenya, while experiencing discrimination, leading to suboptimal levels of HIV care. HIV self-testing (HIVST) is a tool to increase HIV screening and earlier diagnosis; however, questions remain regarding how best to scale-up HIVST to MSM in Kenya. The main objective of this study was to examine changes in knowledge and use of HIVST after implementation of a community-led HIVST project. Participants were MSM recruited from Kisumu, Mombasa, and Kiambu counties. Data were collected from two rounds (Round 1: 2019; Round 2: 2020) of serial cross-sectional integrated biological and behavioural assessments (IBBA), pre-, and post-project implementation. Two main outcomes were measured: 1) whether the respondent had ever heard of HIVST; and 2) whether they had ever used HIVST kits. Changes in outcomes between IBBA rounds were examined using modified multivariable Poisson regression models; adjusted prevalence ratios (aPR) and 95% confidence intervals (95% CI) are reported. A total of 2,328 respondents were included in main analyses. The proportion of respondents who had heard of HIVST increased from 75% in Round 1 to 94% in Round 2 (aPR: 1.2, 95% CI: 1.2-1.3), while those reporting using an HIVST kit increased from 20% to 53% (aPR: 2.3, 95% CI: 2.0-2.6). Higher levels of education and HIV programme awareness were associated with both outcomes. Awareness and use of HIVST kits increased after implementation of a community-led HIVST implementation project, demonstrating the importance of integration with existing community groups.

RESUMEN

Inferring HIV transmission networks from HIV sequences is gaining popularity in the field of HIV molecular epidemiology. However, HIV sequences are often analyzed at distance from those affected by HIV epidemics, namely without the involvement of communities most affected by HIV. These remote analyses often mean that knowledge is generated in absence of lived experiences and socio-economic realities that could inform the ethical application of network-derived information in 'real world' programmes. Procedures to engage communities are noticeably absent from the HIV molecular epidemiology literature. Here we present our team's protocol for engaging community activists living in Nairobi, Kenya in a knowledge exchange process - The CIPHR Project (Community Insights in Phylogenetic HIV Research). Drawing upon a community-based participatory approach, our team will (1) explore the possibilities and limitations of HIV molecular epidemiology for key population programmes, (2) pilot a community-based HIV molecular study, and (3) co-develop policy guidelines on conducting ethically safe HIV molecular epidemiology. Critical dialogue with activist communities will offer insight into the potential uses and abuses of using such information to sharpen HIV prevention programmes. The outcome of this process holds importance to the development of policy frameworks that will guide the next generation of the global response.

RESUMEN

OBJECTIVES: To assess the levels and trends in the prevalence of HIV and sexually transmitted infections in the general population in Bagalkot district using 2 cross-sectional surveys undertaken in 2003 and 2009. METHODS: In both surveys, a target sample of 6600 adult males and females was selected systematically from a sample of 10 rural villages and 20 urban blocks in 3 of the 6 talukas (subdistrict units) in the district. Urine and blood samples were collected from all consenting participants for HIV and sexually transmitted infection testing. Changes in HIV prevalence in age subgroups were determined by logistic regression, taking into account the survey design. RESULTS: HIV prevalence fell not significantly from 3.2% to 2.5% during the 6-year study period. It decreased significantly (P = 0.023) among persons aged 15 to 24 years, from 2.4% in 2003 (95% confidence interval [95% CI]: 1.2-3.7) to 1.3% in 2009 (95% CI: 0.6 -2.0). However, among males aged 35 and above, HIV prevalence increased significantly (P = 0.008), from 3.0% (95% CI: 1.1-4.8) to 4.2% (95% CI: 1.8-6.6), a level similar to that found in the younger age-group in 2003. CONCLUSIONS: We observed a significant decline in HIV prevalence among people aged 15 to 24 years, where HIV prevalence more closely reflects incidence. The increase in HIV prevalence among older males may have been because of the aging of a cohort of men among whom HIV prevalence was highest in the 2003 survey. It may also have in part reflected increased survival, as a result of the scaling up of antiretroviral treatment programs throughout the district and state.
