RESUMO

HIV is highly prevalent in men who have sex with men (MSM) in West Africa. Many MSM in the region also have sex with women (MSMW). Accordingly, they are a potential bridge subpopulation for HIV transmission to women. We aimed to evaluate the proportions and characteristics of West African MSMW at high behavioral risk of acquiring HIV from male partners and transmitting it to female partners (HBRMF). The cohort ANRS-12324 CohMSM Study included 630 HIV-negative MSM in Burkina Faso, Cote d'Ivoire, Mali, and Togo. Among MSMW (i.e., with ≥ 1 female partner) in the cohort, HBRMF was identified using trajectory models based on seven at-risk sexual practices with male and female partners, including inconsistent condom use, multiple partnerships, and receptive same-sex anal intercourse. To assess the relevance of using trajectory models, we compared the proportions of participants who seroconverted during the cohort follow-up among those at HBRMF and those not at HBRMF. Factors associated with HBRMF were identified using a generalized estimation equation logistic regression model accounting for longitudinal data. Approximately half (47%) of the 304 MSMW (22% of all CohMSM study participants) were at HBRMF. This group accounted for 75% of the 28 HIV seroconversions observed during follow-up (p = 0.001). HBRMF was positively associated with being aged < 25 years (aOR 95% CI 1.67 [1.23-2.27]), being sexually attracted only to men (1.97 [1.38-2.78]), feelings of loneliness (1.92 [1.38-2.65]), and homonegative violence score (1.22 [1.05-1.41]). HBRMF was negatively associated with having had both stable and casual female partners in the previous 6 months (0.34 [0.20-0.60] vs. only a stable female partner). HBRMF tended to be negatively associated with having ≥ 4 sexual intercourses with female partners in the previous four weeks (0.54 [0.27-1.06] vs. no intercourse). Establishing official relationships with women might be a strategy for young and/or stigmatized MSMW to comply with social pressure to display a heterosexual lifestyle. However, this seems to increase the risk of HIV transmission to female partners. In the present study, almost half of MSMW were at HBRMF. This result stresses the need to adapt HIV research and prevention to MSMW and their female partners.

RESUMO

PURPOSE: This study aimed to provide a better understanding of the patient-perceived effects of France's first COVID-19-related lockdown on the quality of life (QoL) of women affected by cancer, and to test an ad hoc measurement scale for evaluating quasi-individualized QoL. QoL was measured for both during (i.e., current) and before (i.e., retrospectively) the lockdown. Respondents were women registered on the research platform Seintinelles. METHODS: A tool for measuring quasi-individualized QoL was adapted from the SeiQol-DW and PGI. It was distributed as part of a larger online self-questionnaire to a sample of 1303 women with a history of cancer (i.e., former or current) and with no such history. RESULTS: Current and retrospective QoL scores were not significantly different between the two respondent groups. An analysis of reconceptualization and reprioritization revealed a cancer-specific effect: women with a history of cancer reconceptualized more, while women with no such history reprioritized more. CONCLUSION: Our novel ad hoc quasi-qualitative tool made it possible to assess the QoL of women with a history of cancer, a particularly vulnerable population in the context of the COVID-19 pandemic. Furthermore, it highlighted a difference in reconceptualization and reprioritization between this population and women with no such history.

RESUMO

BACKGROUND: Data on human immunodeficiency virus (HIV) seroconversion among men who have sex with men (MSM) using pre-exposure prophylaxis (PrEP) in West Africa are needed. This study aimed to document HIV seroconversion and associated determinants, PrEP adherence, plasma drug concentrations, and HIV drug resistance in MSM using event-driven or daily PrEP in Burkina Faso, Côte d'Ivoire, Mali, and Togo. METHODS: A prospective cohort study was conducted in 2017-2021 among HIV-seronegative MSM aged 18 or over who were at high risk of HIV infection. Participants could choose between event-driven and daily PrEP, switch regimens, and discontinue or restart PrEP. The determinants of HIV incidence were investigated using a multivariate mixed-effects Poisson regression analysis. RESULTS: A total of 647 participants were followed for a total time of 1229.3 person-years. Of 5371 visits, event-driven PrEP was chosen in 3873 (72.1%), and daily PrEP in 1400 (26.1%). HIV incidence was 2.4 per 100 person-years (95% confidence interval [CI] 1.5-3.6) for event-driven PrEP, and 0.6 per 100 person-years (95% CI .1-2.3) for daily PrEP (adjusted incidence rate ratio 4.40, 95% CI 1.00-19.36, P = .050). Adequate adherence was lower with event-driven than daily PrEP (44.3% vs 74.9%, P < .001). Plasma drug concentrations were undetectable in 92 (97.9%) of the 94 measures taken for 23 participants who seroconverted. Only 1 participant had resistance to PrEP drugs. CONCLUSIONS: HIV seroconversions mainly occurred in participants who chose event-driven PrEP. The study's data highlighted major difficulties with adherence to this regimen. Improving adherence to event-driven PrEP constitutes a major research and public health priority in this context.

RESUMO

Most domestic servants (DS) in Mali are very young female migrants living in precarious conditions. We aimed to understand their living and working conditions in relation to their general and sexual health. Seven focus groups (53 participants) were conducted by the DS community-based organization ADDAD. Narratives were thematically analyzed using an inductive method. The dominant emerging theme was DS' strong dependence on their employers. Employers' attitudes regarding DS workload, the provision of food, water and hygiene products, housing conditions, and healthcare cover, appeared decisive for DS' physical and mental health, and the type of healthcare they used (self-medication, traditional care, healthcare facilities). Psychological, physical and sexual violence in employers' households was frequent. HIV/STI prevention knowledge was poor. These results highlight the serious risks for DS in terms of HIV/STI and unwanted pregnancies. DS were interested in receiving healthcare from ADDAD; this was motivated by the organization's trusting and understanding community-based environment, and DS' fear of discrimination in healthcare facilities. This study highlights the relevance of tackling the defense of rights and sexual health promotion for DS at the community level. Its findings can help identify research questions to evaluate the extent to which DS constitute a key HIV population.

RESUMO

Observing sexual behaviour change over time could help develop behavioural HIV prevention interventions for female sex workers in Zambia, where these interventions are lacking. We investigated the evolution of consistent condom use among female sex workers and their clients and steady partners. Participants were recruited into an HIV incidence cohort from 2012 to 2017. At each visit, women received HIV counselling and testing, screening for sexually transmitted infections (STIs) and free condoms. Our outcome was reported consistent (100%) condom use in the previous month with steady partners, repeat clients, and non-repeat clients. Consistent condom use at baseline was highest with non-repeat clients (36%) followed by repeat clients (27%) and steady partners (17%). Consistent condom use between baseline and Month 42 increased by 35% with steady partners, 39% with repeat clients and 41% with non-repeat clients. Access to condoms, HIV/STI counselling and testing promoted positive sexual behaviour change.

RESUMO

We investigated the rate and predictors of ineffective HIV protection in men who have sex with men (MSM) taking pre-exposure prophylaxis (PrEP) in a prospective cohort study from November 2017 to November 2020 in Mali, Côte d'Ivoire, Burkina Faso, and Togo. MSM had to be 18 years or older and at high risk of HIV infection to participate. They also received a comprehensive sexual health prevention package, including PrEP, in community-based clinics as part of the cohort study. Using socio-behavioral/clinical data, HIV protection during their most recent anal intercourse with a male partner was categorized as effective or ineffective (i.e., incorrect PrEP adherence and no condom use). Seventeen percent (500/2839) of intercourses were ineffectively protected for the 520 study participants. Predictors of ineffective HIV protection included being an event-driven user with financial difficulties, having a high alcohol misuse score, and not being a member of a community association. PrEP programs in West Africa must be tailored to socially vulnerable MSM who struggle to adopt PrEP.


RESUMEN: En este artículo hemos investigado la proporción y los factores predictivos de la protección ineficaz de VIH en un grupo de hombres, que tienen sexo con hombres (HSH) y que usan la profilaxis pre-exposición (PrEP). Se usaron los datos de un estudio de cohorte prospectivo realizado entre noviembre del 2017 y noviembre del 2020 en Mali, Costa de Marfil, Burkina Faso y Togo. Los participantes son HSH, de 18 años o más, y con alto riesgo de contaminación por el VIH. Estos han recibido un paquete completo de prevención en salud sexual incluyendo la PrEP en clínicas comunitarias como parte del estudio de cohorte. La protección contra el VIH durante la última relación sexual anal con un hombre fue categorizada como eficaz o ineficaz a partir de datos socio-comportamentales/clínicos (i.e. adhesión incorrecta à la PrEP y no utilización del condón). Concerniente a 520 participantes, 17% (500/2839) de las relaciones sexuales fueron protegidas de manera ineficaz. Entre los factores predictivos de la protección ineficaz contra el VIH se encuentran, el uso intermitente de la PrEP asociado a una situación financiera difícil, el consumo de alcohol y no ser miembro de una asociación comunitaria. Los programas de PrEP en África del Oeste, deben adaptarse a los HSH más vulnerables quienes podrían tener más dificultad para adoptar la PrEP.

RESUMO

BACKGROUND: Multiple barriers compromise pre-exposure prophylaxis (PrEP) engagement (i.e., use and adherence) in men who have sex with men (MSM). In low/middle-income countries, little is known about PrEP engagement in this population. In West Africa, the CohMSM-PrEP study was one of the rare interventions providing PrEP to MSM. We estimated PrEP use and correct adherence rates in CohMSM-PrEP, together with associated factors over time.  METHODS: CohMSM-PrEP recruited MSM in four community-based clinics in Mali, Côte d'Ivoire, Burkina Faso, and Togo. Quarterly follow-up included collecting socio-behavioral data, and providing a comprehensive HIV prevention package, PrEP (daily or event-driven), and peer educator (PE)-led counselling. Using repeated measures, multivariate generalized estimating equations models were used to identify factors associated with self-reported i) PrEP use and ii) correct PrEP adherence during participants' most recent anal intercourse (defined as four pills/week for daily users and 2 + 1 + 1 for event-driven users). RESULTS: Five hundred twenty participants were included with a median follow-up time of 12 months (IQR 6-21). Of the 2839 intercourses declared over the follow-up period, PrEP use was self-reported for 1996 (70%), and correct PrEP adherence for 1461 (73%) of the latter. PrEP use was higher in participants who also attended participating clinics outside of scheduled visits (adjusted odds ratio (aOR) [95% Confidence Interval, CI], p-value; 1.32[1.01-1.71], 0.040), and in those who practiced condomless anal sex (1.86[1.54-2.24], < 0.001). Correct adherence was higher in those who often contacted PE outside of scheduled visits (2.16[1.01-4.64], 0.047) and in participants who adopted receptive/versatile sexual positions with stable partners (1.36[1.03-1.81], 0.030). Instead, after an interaction effect between financial situation and regimen was tested, it was lower in event-driven users with a difficult/very difficult financial situation (comfortable/just making ends meet & daily, 4.19[2.56-6.86], < 0.001; difficult/very difficult & daily, 6.47[4.05-10.30], < 0.001; comfortable/just making ends meet & event-driven, 1.63[1.22-2.17], 0.001), and in participants who felt alone (0.76[0.58-0.99], 0.042). CONCLUSIONS: Community-based clinic attendance and PE contact outside of scheduled visits were both associated with higher PrEP engagement, but some socially and economically marginalized participants struggled with adherence. As scale-up continues in West Africa, we recommend implementing community-based interventions and providing extra support for vulnerable users to ensure adequate PrEP engagement.

RESUMO

BACKGROUND: The prevalence of receptive anal intercourse (RAI) is increasing. A few studies, with heterogeneous designs, have investigated the associated risk of fecal incontinence (FI). AIM: The primary objective of this study was to determine FI prevalence in a population of men who have sex with men (MSM) engaging in RAI. The secondary objective was to identify risk factors for severe FI. METHODS OUTCOMES: An online survey of 24,308 MSM was performed in 2019. Demographic and socioeconomic data were collected, together with information about RAI sexual practices, and FI defined by: "During the last month, have you experienced any involuntary leakage of stools?" RESULTS CLINICAL IMPLICATIONS: In total, 1,734 (8%) of the 21,762 participants reported FI. Mean age was 35.3 years. The prevalence of FI was correlated with RAI frequency: 12.7% (if RAI ≥ 1 /wk) versus 5.7% (if no RAI). In multivariate analysis, the factors associated with FI were age (OR: 1.01), low socioeconomic status (OR 1.32 to 1.40), HIV-seropositivity (OR: 1.78), high RAI frequency (OR: 1.64), chemsex (OR: 1.67) and fist-fucking (OR: 1.61). STRENGTHS AND LIMITATIONS: Main strengths of our study are population size and assessment of detailed modalities of sexual practices. Main limitations are the use of a convenience non-random sample and the assessment of FI only during the past month. CONCLUSION: This study of a large MSM population, highlights risk factors for FI among RAI practices: RAI ≥ 1 /wk, chemsex, fist-fucking, low socioeconomic status.

RESUMO

BACKGROUND: Access to tailored HIV prevention services remains limited for West African MSM. We assessed adherence to quarterly HIV prevention services and its impact on HIV incidence in MSM followed up in four cities in Burkina Faso, Côte d'Ivoire, Mali, and Togo. METHODS: We performed a prospective cohort study between 2015 and 2018. HIV-negative MSM aged over 18 benefited from quarterly medical visits which included a clinical examination, HIV testing, screening and treatment for other sexually transmitted infections, peer-led counselling and support, and the provision of condoms and lubricants. Determinants of adherence to quarterly follow-up visits and incident HIV infections were identified using generalized estimating equation models and Cox proportional hazard models, respectively. RESULTS: 618 MSM were followed up for a median time of 20.0 months (interquartile range 15.2-26.3). Overall adherence to quarterly follow-up visits was 76.5% (95% confidence interval [CI] 75.1-77.8), ranging from 66.8% in Abidjan to 87.3% in Lomé (p < 0.001). 78 incident HIV infections occurred during a total follow-up time of 780.8 person-years, giving an overall incidence of 10.0 per 100 person-years (95% CI 8.0-12.5). Adherence to quarterly follow-up visits was not associated with the risk of incident HIV infection (adjusted hazard ratio 0.80, 95% CI 0.44-1.44, p = 0.545). CONCLUSIONS: Strengthening HIV prevention services among MSM in West Africa, including the use of PrEP, will be critical for controlling the epidemic, not only in this key population but also in the general population. Quarterly follow-up of MSM, which is essential for PrEP delivery, appears feasible. TRIAL REGISTRATION: ClinicalTrials.gov, number NCT02626286 (December 10, 2015).

RESUMO

OBJECTIVES: Whether regular HIV testing and counselling reduce risky sexual behaviours in African men who have sex with men (MSM) is still a matter for debate. We aimed to identify behavioural trajectories based on HIV risk exposure (HRE) and factors affecting their evolution. METHODS: Data were collected from 621 HIV-negative West African MSM (Mali, Cote d'Ivoire, Burkina Faso and Togo) included in a community-based cohort providing quarterly HIV testing and counselling. Sociobehavioural data were collected every 6 months. HRE was defined as reporting inconsistent condom use during receptive anal sex with male partners of unknown HIV status in the previous 6 months. Using 18-month follow-up data, group-based trajectory modelling helped identify behavioural trajectories and determine the factors associated with their evolution. HIV seroconversions (n=67) were specified in each group trajectory. RESULTS: Two distinct group trajectories were identified: medium-risk exposure MSM (ME-MSM) (61%, 6.4% of whom having seroconverted) and high-risk exposure MSM (HE-MSM) (39%, 17.5% of whom having seroconverted). A significant declining trend in the probability of reporting HRE over time ((95% CI)) was observed for HE-MSM (from 0.59 (0.48 to 0.70) at M0 to 0.31 (0.22 to 0.41) at M18), while it remained constant for ME-MSM (0.034 (0.0 to 0.079)). This can be explained by a progressive use of risk reduction strategies (less receptive anal sex, better knowledge of their partners' status and increasing condom use). Being younger, living in Burkina Faso, self-considering both a man and a woman and reporting a higher level of depression were all associated with HE membership. Among HE-MSM, HRE was higher in those practising transactional or group sex and those experiencing psychological harassment. CONCLUSIONS: Quarterly HIV testing and counselling seem to reduce risky sexual behaviours in HIV-negative MSM at greatest risk of infection. Specific support for young MSM, focusing on identity and mental health, is needed to strengthen HIV prevention in West African MSM.

RESUMO

OBJECTIVES: To estimate geographical variations of child immunisation at the regional level in Senegal, to identify individual and contextual factors that could explain these regional discrepancies, and to measure their effects. METHODS: Data come from the 2015, 2016 and 2017 Senegalese Demographic and Health Survey, a national survey targeting women aged 15-49, with a questionnaire focusing on health and reproductive issues including their children's immunisation status. We restricted the analysis to children aged 12-23 months (n = 4955) and conducted a multilevel logistic regression to assess individual and contextual factors associated with complete immunisation coverage. RESULTS: The complete immunisation coverage rate of children was estimated at 68% and ranged from 41% in the region of Kedougou to 83% in the region of Dakar. The inter-regional variance was significantly different from zero (P = 0.006) in the empty multilevel model. It decreased by more than half (57 %) after adjusting for individual factors but remained significantly different from zero (P = 0.010). Regional variations of complete immunisation rates drastically decreased and were no longer statistically significant (P = 0.343) after adjusting for the following regional factors: population density, density of hospitals, literacy rate and proportion of health facilities with an antenatal care service. CONCLUSIONS: Regarding health policies designed to improve childhood immunisation and to reduce related inequalities, our results highlight the need to take into account both individual and contextual factors, with a focus on rural and deprived areas where children are at higher risk of incomplete immunisation.


OBJECTIFS: Estimer les variations géographiques de la vaccination des enfants au niveau régional au Sénégal, identifier les facteurs individuels et contextuels qui pourraient expliquer ces écarts régionaux et mesurer leurs effets. MÉTHODES: Les données proviennent de l'enquête démographique et la santé du Sénégal de 2015, 2016 et 2017, une enquête nationale ciblant les femmes âgées de 15 à 49 ans, avec un questionnaire axé sur les problèmes de santé et de reproduction, y compris le statut vaccinal de leurs enfants. Nous avons limité l'analyse aux enfants âgés de 12 à 23 mois (n = 4.955) et avons effectué une régression logistique à plusieurs niveaux pour évaluer les facteurs individuels et contextuels associés à une couverture vaccinale complète. RÉSULTATS: Le taux de couverture vaccinale complète des enfants était estimé à 68% et variait de 41% dans la région de Kédougou à 83% dans la région de Dakar. La variance interrégionale était significativement différente de zéro (P = 0,006) dans le modèle vide à plusieurs niveaux. Il diminuait de plus de la moitié (57%) après ajustement pour les facteurs individuels mais est restait significativement différent de zéro (P = 0,010). Les variations régionales des taux de vaccination complète ont considérablement diminué et n'étaient plus statistiquement significatives (P = 0,343) après ajustement pour les facteurs régionaux suivants: densité de population, densité des hôpitaux, taux d'alphabétisation et proportion d'établissements de santé disposant d'un service de soins prénatals. CONCLUSIONS: En ce qui concerne les politiques de santé conçues pour améliorer la vaccination des enfants et réduire les inégalités associées, nos résultats soulignent la nécessité de prendre en compte les facteurs individuels et contextuels, en mettant l'accent sur les zones rurales et défavorisées où les enfants sont plus à risque de vaccination incomplète.

RESUMO

Pre-Exposure Prophylaxis (PrEP) is changing the landscape of HIV prevention, and may bring changes in sexual behaviors. The double-blind phase (DBP) and open-label extension (OLE) study of the ANRS-IPERGAY trial allowed us to assess changes in sexual behavior of men who have sex with men (MSM) taking sexual activity-based (i.e., on-demand) PrEP. Generalized Estimating Equation (GEE) models found a significant decrease in the number of sexual partners (Coefficient [CI95%], p value; - 0.37[- 0.70 to - 0.04], p = 0.03) between the DBP and OLE as well as in the number of sexual relations (- 0.25 [- 0.49 to 0.00], 0.04). GEE estimates also showed that respondents' most recent sexual relation was less likely to have been with an unknown casual partner during the OLE than during the DBP (Odds Ratio [CI95%], p value: 0.75[0.62-0.92], 0.005). Furthermore, they showed an increase in the proportion of condomless anal sex in the OLE (1.32[1.04-1.67], 0.02), a decrease in the proportion of 'suboptimal PrEP adherence' over time (0.75[0.58-0.97], p = 0.03), a decrease in PrEP only use (0.73[0.55-0.96], 0.03) and in both PrEP and condom use over time (0.70[0.51-0.95], 0.02) and finally, a decrease in alcohol consumption between the DBP and OLE (0.74[0.61-0.90], 0.002). We observed both protective and risky behaviors in terms of HIV and STI risk after on-demand PrEP uptake in the OLE phase. Our findings are consistent with results from previous PrEP trials.

RESUMO

Understanding the dynamics of HIV infection in men who have sex with men (MSM) can help improve efficiency in existing prevention strategies. We aimed to identify and describe the sexual behaviors of MSM most at risk of HIV infection in West Africa. HIV-negative MSM were provided a quarterly preventive follow-up package in the community-based cohort CohMSM. They completed face-to-face sociobehavioral questionnaires every 6 months. This sub-study on 520 participants used a baseline, 6-, 12- and 18-month data cluster analysis to categorize two profiles (high risk [HRE] and moderate risk [MRE] of exposure to HIV) based on three risky sexual practices over the previous 6 months. HRE-MSM (61%) were more engaged in receptive practices, had a higher proportion of inconsistent condom use during anal sex, and reported more sexual partners than MRE-MSM (39%). The proportion of HIV seroconversions observed during the first 18 months of follow-up using sexual behavioral profiles (92% are HRE-MSM) was higher than using the three risky sexual practices separately. Factors associated with the HRE-MSM profile were being younger (18-21 years), reporting stigma, and having had no female partner while being attracted only to men. Our findings suggest that in order to identify MSM most at risk of HIV infection, several risky sexual practices need to be evaluated in a combined approach. Prevention programs should pay particular attention to younger MSM, and implement activities addressing questions of MSM identity and stigma in order to reduce the dynamic of HIV infection in Western African MSM.

RESUMO

HIV-incidence studies are used to identify at-risk populations for HIV-prevention trials and interventions, but loss to follow-up (LTFU) can bias results if participants who remain differ from those who drop out. We investigated the incidence of and factors associated with LTFU among Zambian female sex workers (FSWs) in an HIV-incidence cohort from 2012 to 2017. Enrolled participants returned at month one, month three and quarterly thereafter. FSWs were considered LTFU if they missed six consecutive months, or if their last visit was six months before the study end date. Of 420 FSWs, 139 (33%) were LTFU at a rate of 15.7 per 100 person years. In multivariable analysis, LTFU was greater for FSWs who never used alcohol, began sex work above the age of consent, and had a lower volume of new clients. Our study appeared to retain FSWs in most need of HIV-prevention services offered at follow-up.

RESUMO

People living with HIV who spontaneously control the virus without antiretroviral treatment are called HIV Controllers and their status places them at the limits of bio-clinical normality. The objective of this study was to investigate an unexplored field: HIV Controllers' quality of life (QOL). Using quantitative methods, we compared the QOL of untreated (by definition) HIV Controllers in the ANRS CO18 HIV Controller cohort study, with the QOL of treated patients in the French national survey ANRS VESPA 2. In particular, the physical, social, mental and sexual dimensions of QOL were examined. Results highlight that perceiving oneself to be ill or healthy is linked to stigma and to a lack of self-identification with a social group. Some components of the QOL were significantly impaired in HIV controllers. This study is the first to investigate this field.

RESUMO

BACKGROUND: Unlike their younger counterparts, some of today's older HIV patients were diagnosed before the advent of highly active antiretroviral therapy (HAART). The psychosocial and behavioral outcomes of people living with HIV (PLWH) have been widely studied, and associated factors are well known. However, their evolution both in terms of age and diagnosis-specific cohort effects is not well understood. METHODS: Data from the ANRS-VESPA2 cross-sectional survey, representative of French PLWH, were used to investigate whether psychosocial and behavioral outcomes such as quality of life, need for support and HIV status disclosure, evolve under both the influence of patients' age and diagnosis-specific cohort effects. A semi-parametric generalized additive model (GAM) was employed. The physical and mental components of health-related quality of life, the need for material and moral support, and HIV-status disclosure, constituted our outcomes. RESULTS: Non-linear diagnosis-specific cohort effects were found for physical and mental QoL and HIV-status disclosure. Overall, physical QoL was better in recently diagnosed patients than in those diagnosed in the early 1980s. An increasing influence of diagnosis-specific cohort effects between 1983 and 1995 was observed. No cohort effects were noticeable between 1996 and 2000, while an increasing influence was apparent for patients diagnosed with HIV from 2000 to 2011 (year of study). For mental QoL, the only increase was observed in participants diagnosed with HIV between 1983 and 2000. The relationship between diagnosis-specific cohort effects and HIV status disclosure was negative overall: participants diagnosed after 2000 were much less likely to disclose than those diagnosed before 1995. The effect of age was significantly associated with all outcomes, with a non-linear influence on mental QoL and with the need for material/moral support. CONCLUSIONS: Psychosocial and behavioral outcomes are complex processes which can be explained in different ways by a combination of the clinical and social contexts which PLWH are exposed to at the time of diagnosis, and by developmental characteristics. A greater understanding of these processes could inform healthcare policy-making for specific HIV generations and different HIV age groups.

RESUMO

Female sex workers (FSW) in mining sites are considered to be at very high risk of HIV infection. We aimed to characterize FSW at the Kôkôyô artisanal gold mining site in Mali, and identify factors associated with sex work using data from ANRS-12339 Sanu Gundo, a cross-sectional survey conducted in 2015 at the mine by ARCAD-SIDA, a Malian non-governmental organisation. People attending HIV-prevention activities were invited to participate in the quantitative and qualitative parts of the survey. A probit logistic regression was used for data analysis. Of 101 women who participated in the survey, 26.7% reported sex work as their main activity. Multivariate analysis showed that the probability of sex work as a main activity decreased by 1% per 1-year age increase (p = 0.020). Sex work was significantly more likely to be reported by single, divorced and widowed women (25.4% probability; p = 0.007). FSW were significantly more likely to be non-Malian (36.3% probability; p = 0.003), more likely to have a secondary activity (77% probability; p = 0.002), to work fewer than 56h/week (40.2% probability; p = 0.001) and to be in good health (12.1% probability; p = 0.016). In addition, being aware of the existence of sexually transmitted infection, using psychoactive substances, and having unprotected receptive anal sex during the previous six months were significantly associated with sex work (50.2%; p = 0.006; 45.6%, p = 0.003; and 7.4%, p = 0.016 probability, respectively). Qualitative findings confirm that poverty and boyfriends' refusal to use condoms remain key barriers to systematic condom use among FSW.

RESUMO

INTRODUCTION: Decreasing international financial resources for HIV and increasing numbers of antiretroviral treatment (ART)-treated patients may jeopardise treatment continuity in low-income settings. Using data from the EVOLCam ANRS-12288 survey, this study aimed to document the prevalence of unplanned treatment interruption for more than 2 consecutive days (TI>2d) and investigate the associated individual and health care supply-related factors within the Cameroonian ART programme. METHODS: A cross-sectional mixed methods survey was carried out between April and December 2014 in 19 HIV services of the Centre and Littoral regions. A multilevel logistic model was estimated on 1885 ART-treated patients in these services to investigate factors of TI>2d in the past 4 weeks. RESULTS: Among the study population, 403 (21%) patients reported TI>2d. Patients followed up in hospitals reporting ART stock-outs were more likely to report TI>2d while those followed up in the Littoral region, in medium- or small-sized hospitals and in HIV services proposing financial support were at lower risk of TI>2d. The following individual factors were also associated with a lower risk of TI>2d: living in a couple, having children, satisfaction with attention provided by doctor, tuberculosis co-infection and not having consulted a traditional healer. CONCLUSIONS: Besides identifying individual factors of TI>2d, our study highlighted the role of health care supply-related factors in shaping TI in Cameroon's ART programme, especially the deleterious effect of ART stock-outs. Our results also suggest that the high proportion of patients reporting TI could jeopardise progress in the fight against HIV in the country, unless effective measures are quickly implemented like ensuring the continuity of ART supply.

RESUMO

OBJECTIVE: To explore the interest in taking PrEP among Western African men who have sex with men (MSM). METHODS: A cross-sectional survey was implemented at enrolment of HIV-negative MSM in a multiple centre community-based cohort study in four West African countries (Mali, Côte d'Ivoire, Burkina Faso, Togo). A standardised face-to-face questionnaire collected data on socio-demographic and behavioural characteristics over the previous 6 months. Descriptive analysis and multivariate logistic regression helped identify factors associated with the interest in taking PrEP. RESULTS: Of 564 participants, 87% were interested in taking PrEP. Interest in PrEP was associated with inconsistent condom use for anal sex (adjusted odds ratio (aOR): 2.11; 95% confidence interval (CI) 1.21-3.67), transactional sex (aOR: 2.02; 95% CI 1.11-3.71), searching for male sexual partners on the Internet in the previous month (aOR: 1.86; 95% CI 1.01-3.43), having a high level of self-esteem (aOR: 1.20; 95% CI 1.06-1.36), having at least one sexually transmitted infections at enrolment (aOR: 5.08; 95% CI 1.40-18.4) and not being aware of PrEP (aOR: 2.03; 95% CI 1.04-3.96). Participants having sex with HIV-positive male partners (aOR: 0.28; 95% CI 0.11-0.74), those being more sexually attracted to women than to men (aOR: 0.20; 95% CI 0.07-0.89) and those reporting psychological and material support from close friends (aOR: 0.33; 95% CI 0.15-0.73) were less interested in taking PreP. CONCLUSIONS: Western African HIV-negative MSM appear very interested in taking PrEP, especially those most at risk of HIV infection. PrEP implementation in a comprehensive prevention package should be considered urgently.

RESUMO

OBJECTIVES: To investigate whether adherence to antiretroviral treatment (ART) can be explained not only by individual factors but also by health care facilities' characteristics, among a sample of people living with HIV (PLWH) treated with PI-based regimens in Cambodia. METHODS: The ANRS 12276 2PICAM cross-sectional survey was conducted between February 2013 and April 2014 among PLWH followed up in 13 health care facilities. The 1316 patients in this analysis corresponded to 90% of the total number of adult patients treated with 2nd-line PI-based regimens in Cambodia in the study period. A variable indicating whether patients were non-adherent (=1) or completely adherent (=0) was constructed. Health care facilities and individual characteristics were included in a two-level logistic model to investigate their influence on patients' adherence to ART. RESULTS: A total of 17% of participants did not adhere to ART. Patients in health care facilities outside the capital Phnom Penh were six times more likely to be non-adherent than those treated in health care facilities in the capital (OR: 6.15, 95% CI [1.47, 25.79]). Providing psychosocial care (provided by psychologist counsellors and/or full-time coaches) was found to be a structural facilitator of adherence, as the probability of non-adherence fell by 38.5% per each additional psychological worker present in health care facilities (OR: 0.62, 95% CI [0.43, 0.89]). Financial constraints were the main individual factor preventing adherence. CONCLUSIONS: Our results suggest that inefficiencies in health care delivery are detrimental to PLWH health and to the exceptional progress currently being made by Cambodia in response to HIV. Policy makers should focus on increasing the number of psychosocial workers, especially in areas outside the capital.
