Résumé : International audience
In French Guiana, the prevalence of HIV among pregnant women along the Maroni river, has risen from 0 to over 1% in the 1990's. Despite this sharp increase, no behavioural surveillance study has ever taken place in this border region. The present study showed that an important proportion of boatmen have risky sexual behaviour. These results underline the importance of targeting prevention interventions on this population that is not currently receiving specific HIV prevention messages.

Résumé : International audience
: French Guiana is the French territory that is most affected by HIV. AIDS incidence is much higher than in mainland France and sex work seems to be an important driver of the epidemic. The objective of this study was to describe consistent condom use among female sex workers with their clients and their intimate partners and to identify determinants of non-use of condoms. An HIV/AIDS Knowledge, Attitudes, Behaviours and Practices survey was conducted in 2009-2010 among sex workers in French Guiana. A total of 477 sex workers were interviewed. Female sex workers were more likely to use condoms with their clients (97%) than with their intimate partners (45%). The factors associated with non-consistent condom use with the intimate partner were having had an abortion, feeling at risk for HIV, not evaluating one's own risk for HIV, living as a couple, being Dominican, not feeling comfortable asking intimate partners to use condoms. Although a high proportion of female sex workers declared using condoms with commercial partners, there is still room for improvement in the prevention of transmission with both commercial and intimate partners.

Résumé : International audience
Background: Access to health care is a global public problem. In French Guiana, there exists social inequalities which are specially marked amongst immigrants who make up a third of the population. Health care inequalities are prevalent. The objective of this study was to determine factors associated with why health care amongst the poor population of Cayenne was renounced.Study design The study was cross sectional. It focused on knowledge, attitudes, practices and beliefs of the population living in poor neighborhoods of the Cayenne area. Methods: Populations coming at the Red Cross mobile screening unit in poor urban areas of Cayenne were surveyed from July 2013 to June 2014. Structured questionnaires consisted of 93 questions. Written informed consent was requested at the beginning of the questionnaire. The predictors for renouncing medical care were determined using logistic regression models and tree analysis. Results: Twenty percent of persons had renounced care. Logistic regression showed that renouncement of health care was negatively associated with having no regular physician Adjusted Odds Ratio (AOR)=0.43 (95%CI=0.24-0.79) and positively associated with being embarrassed to ask certain questions AOR=6.81 (95%CI=3.98-11.65) and having been previously refused health care by a doctor AOR=3.08 (95%CI=1.43-6.65) . Tree analysis also showed that three of these variables were linked to renouncement, with feeling shy to ask certain questions as the first branching.Conclusion: Although most people felt it was easy to see a doctor, one in five had renounced health care. The variables identified by the models suggest vulnerable persons generally had previous negative encounters with the health system and felt unwanted or non eligible for healthcare. Health care mediation and welcoming staff may be simple solutions to the above problems which were underscored in our observations.

Résumé : International audience
The French Antilles (Martinique, Saint Martin and Guadeloupe) and French Guiana are the French territories most affected by the HIV epidemic. Some population groups such as men who have sex with men (MSM), especially those involved in transactional sex, are thought to be particularly vulnerable to HIV but few data exist to help characterize their health-related needs and thus implement relevant prevention interventions. To fill this knowledge gap, we used data collected from an HIV/AIDS Knowledge, Attitudes, Behaviours and Practices survey conducted in 2012 among MSM living in the French Antilles and French Guiana and recruited through snowball sampling. Our objectives were to compare social and demographic characteristics and sexual behaviours between MSM engaging in transactional sex and MSM not engaging in transactional sex and to identify factors associated with transactional sex involvement using a logistic regression model. A total of 733 MSM were interviewed, 21% of whom reported to undergo transactional sex. Their behaviour and social and demographic characteristics were different from other MSMs’ and they were more exposed to factors that are recognized to potentiate HIVvulnerability, at the individual, community, network and structural levels. The variables positively associated with sex trade involvement were having ever consumed drug (OR = 2.84 [1.23–6.52]; p = .002), having a greater number of sex partners than the median (OR = 8.31 [4.84–14.30]; p < .001), having experienced intimate partner violence (OR = 1.72 [0.99–3.00]; p = .053) and having undergone physical aggression because of sexual orientation (OR = 2.84 [1.23–6.52];p = .014). Variables negatively associated with sex trade involvement were being older (OR = 0.93 [0.90–0.97] per year; p = .001), having a stable administrative situation (OR = 0.10 [0.06–0.19]; p < .001), having a stable housing (OR = 0.29 [0.15–0.55]; p < .001) and being employed full-time (OR = 0.29 [1.23–6.52]; p = .002).

Résumé : International audience
In Cayenne, French Guiana, 80% of HIV+ patients followed at the hospital are migrants. Behavioral information is crucial for optimizing HIV testing for this vulnerable group. Predictors of ignorance of the existence of free VCT centre and willingness to get tested were investigated in 2006 among 398 migrants from Haiti, Guyana, Suriname, and Brazil using a structured questionnaire. Only 27 % of migrants knew simultaneously about the existence of free VCT, its localisation and its operating hours. Factors associated with ignorance of the existence of free VCT centre were birthplace in Haiti, being in French Guiana for less than 3 years, not thinking one's birth country as strongly affected by HIV, and not thinking to be personally at risk for HIV. Factors independently associated with willingness to get tested were thinking to be at risk for HIV, birthplace in Brazil and Haiti, having a high integration level and fear of suffering if HIV test was positive. In order to improve testing among migrants, the accessibility of testing facilities and the knowledge of their whereabouts and operating hours must be improved to promote the desired behaviour among the majority of migrants which is often willing to do the test.

Résumé : International audience
The Maroni basin, an isolated region delineating the border between Suriname and French Guiana has been affected by the human immunodeficiency virus (HIV) epidemic 10 years after coastal French Guiana. However, the rise in HIV prevalence was sharp, exceeding 1% within 10 years. The aim of the present study is to compare, using the first quantitative data from the general population in remote villages, the knowledge, attitudes, and behaviors regarding HIV between Maroon and Amerindian populations, the two most frequent populations living along the Maroni. Data were collected in 2012 using a structured questionnaire among a random sample of 896 individuals residing in the remote villages on the Maroni river. Proportions were compared between the Maroni and the coastal general population, and between Maroon and Amerindian populations. The present study shows significant differences between territories and between communities living on the Maroni river: the multiple sexual partnerships, more common among population living on the Maroni river, were more frequently reported in Maroons than in Amerindians. Condom use was more frequently reported among men on the Maroni river than on the coast, but these findings were reversed for women. Moreover, among people living on the Maroni river, condom use was more frequently reported among Maroons than among Amerindians. Regarding genital factors that may affect transmission, penile implant seemed to have no ethnic boundaries, steam baths seemed specific to Maroon women. The present results should help to improve community-based specific interventions.

Résumé : International audience
Résumé :Introduction : Les départements Français d’Amérique sont à la fois parmi les territoiresfrançais les plus affectés par le VIH et parmi les territoires français les plus impactés par laconsommation de crack. L’épidémie de VIH en Guyane est une épidémie concentrée quitouche plus spécifiquement certains groupes vulnérables. Parmi ces groupes, les usagers decrack sont particulièrement touchés.Matériel et Méthodes : Une étude a été réalisée simultanément dans les trois départements en2012 dans le but de décrire les connaissances, les attitudes et les pratiques vis-à-vis du VIH etdes IST chez les usagers de crack. Au total 640 personnes ont été interrogées. La méthoded’échantillonnage utilisée était non probabiliste et combinait un échantillonnage deconvenance dans les associations recevant ce public (75% de l’échantillon), et unéchantillonnage en boule de neige en dehors afin d’atteindre les personnes ne fréquentant pasles structures (25% de l’échantillon).Résultats : Un tiers des personnes n’utilisait pas systématiquement le préservatif avec lespartenaires occasionnels (36,2%) ou avec les partenaires commerciaux (32,3%), et 64%n’utilisaient pas le préservatif à chaque fois avec les partenaires réguliers. Différents facteursprédictifs de la non utilisation du préservatif ont été identifiés selon le type de partenaire àl’aide d’un modèle log-binomial. Parmi les différents facteurs repérés, deux étaient communsà chaque type de partenaire : la perception élevée de son risque face au VIH et le fait de nepas se sentir à l’aise pour persuader un partenaire à utiliser le préservatif.Discussion : Dans un contexte de multipartenariat, de violences sexuelles fréquentes et dedépistage insuffisant du VIH, la non utilisation systématique du préservatif peut avoir unimpact non négligeable dans la diffusion de l’épidémie. Bien que la non utilisation dupréservatif soit sensiblement inférieure à ce que l’on retrouve dans la littérature, cesproportions traduisent un réel problème.La capacité à persuader un partenaire sexuel à utiliser un préservatif était négativementcorrélée avec la non utilisation du préservatif quel que soit le type de partenaire. Ainsi, ilsemble que lorsque les personnes se sentaient capables de négocier l'utilisation du préservatif,elles l’utilisaient de manière plus systématique. La capacité personnelle perçue est souventconsidérée comme un levier important pour adapter les comportements de santé. Or, elle peutêtre affectée dans des situations de stigmatisation, d’addiction ou de relation violente. Cesrésultats soulignent l’importance d’interventions spécifiques de prévention parmi les usagersde crack et notamment des interventions visant à améliorer le sentiment d’efficacitépersonnelle (perceived self-efficacy) et d’estime de soi.

Résumé : International audience
The French overseas territories in the Americas are the French territories most affected by HIV. Crack cocaine users are particularly impacted. The objective of this study was to describe sexual risk behaviors and inconsistent condom use among crack cocaine users. A total of 640 crack cocaine users were interviewed. The sampling method was non-probabilistic. An anonymous standardized questionnaire of 110 questions was used. Over a third of persons did not use condoms systematically with casual sex partners (36.2%) or commercial sex partners (32.3%), and 64% did not use condoms systematically with regular sex partners. In a context of multiple sexual partnerships, frequent forced sex, and insufficient HIV testing, the lack of systematic condom use may favor the spread of HIV. Different predictive factors of inconsistent condom use were identified, depending on the type of partner, with a log binomial regression. However, among the predictor variables identified, two predictive factors frequently occur among the different type of sex partners: high perceived risk of HIV and self-perceived capacity to persuade a sex partner to use condom. These results pointed towards interventions improving access to rights and raising perceived self-efficacy.
