  • Social deprivation among people living with HIV in the French-swiss Cross-border area: the need for targeted interventions

    by Marie-Claire Parriault, Jules Fontaine, Emilie Piet, Olivier Epaulard, Paule Letertre-Gibert, Alexie Bosch, Mélissa Petrier, Océane Vendrasco, Tristan Delory, Cécile Janssen

    Social deprivation is a major determinant of health inequalities and may affect the trajectory of people living with HIV (PLWH), even in high-income countries with universal healthcare coverage such as France. We conducted a cross-sectional study in 2022 among PLWH followed in rural and urban settings in the French Alps to characterize social deprivation and assess the impact of the Covid-19 pandemic on their socioeconomic situation. Data from 639 participants were collected through medical records and standardized questionnaires, including the EPICES score, a validated measure of individual social deprivation. Among the 595 participants with complete data, 61.5% were classified as socially deprived. Deprivation was independently associated with unstable employment and a monthly income below €1500. During the first Covid-19 lockdown, 10% of initially non-deprived participants became deprived, and the median EPICES score increased by five points. Sub-Saharan African origin, low income and unstable employment were independently associated with this deterioration. These findings indicate that a majority of PLWH in this region experience social deprivation, which was further exacerbated by the Covid-19 pandemic, highlighting the need for locally adapted public health and social interventions targeting the most vulnerable populations.

    Knowledge, attitudes, practices about HIV and implications in risk and stigma prevention among French Guianese and Brazilian border inhabitants

    by E. Mosnier, M. Nacher, M. C. Parriault, C. Dao, B. Bidaud, P. Brousse, M. Gaillet, L. Epelboin, A. M. Mendes, L. Montenegro, et al.

    Background: The border area between French Guiana and Brazil is an active HIV-transmission zone. The aim of the present study was to describe HIV knowledge, risk and the level of stigma among inhabitants of this border area. Methods: A cross-sectional study was conducted among 621 inhabitants over 18 years of age in the border cities of Saint-Georges-de-l’Oyapock in French Guiana and Oiapoque in Brazil. It was conducted between October 2017 and February 2018. An anonymous standardized questionnaire was filled out by culturally-trained mediators, then analyzed using STATA 12. Results: Almost half (45.9%) of the individuals had a low education level. Participants whose native language was Portuguese or French demonstrated better HIV knowledge than other populations, notably native Amerindian and creole-speaking people. HIV risk behavior was more frequent in men and in younger age groups. People with good HIV knowledge reported having performed more HIV tests in the last year than participants with poor knowledge. The stigma level was high and reported in 74.8% of respondents. Conclusions: These results illustrate the need for initiatives to improve HIV prevention among autochthonous populations on both sides of this border area. Cross-border collaboration on health policies could produce common key messages adapted to the education level and multi-linguistic populations who live in this area.

    Air Drep—A Retrospective Study Evaluating the Influence of Weather Conditions and Viral Epidemics on Vaso-Occlusive Crises in Patients with Sickle Cell Disease Living in French Guiana

    by Marie-Claire Parriault, Claire Cropet, Aniza Fahrasmane, Stéphanie Rogier, Michaël Parisot, Mathieu Nacher, Narcisse Elenga

    (1) Objectives: French Guiana is the French territory most affected by sickle cell disease (SCD). This study investigates the associations between different environmental factors relative to climate, infectious outbreaks, and emergency visits or weekly hospital admissions for vaso-occlusive crisis (VOC). The identification of risk factors would lead to better patient care and patient management, and more targeted prevention and therapeutic education for patients with SCD in French Guiana. (2) Methods: This study was performed using data collected from the medicalized information system and emergency medical records of Cayenne General Hospital, between 1 January 2010 and 31 December 2016. ARIMA models were used to investigate the potential impact of weather conditions and flu epidemics on VOC occurrence. (3) Results: During the study period, 1739 emergency visits were recorded among 384 patients, of which 856 (49.2%) resulted in hospitalization, 811 (46.6%) resulted in hospital discharge, and 72 (4.2%) in another orientation. Decreased temperature and decreased humidity were both independent factors associated with an increase of VOC cases (p = 0.0128 and p = 0.0004, respectively). When studying severe VOC (leading to hospitalization, with or without prior emergency visit), 2104 hospital admissions were recorded for 326 patients. The only factor associated with severe VOC, in the multivariate analysis, was flu epidemics (p = 0.0148). (4) Conclusions: This study shows a link between climate, flu epidemics, and VOC in French Guiana. Patient’s awareness of risks related to climate and flu epidemics should be encouraged, as home prevention measures can help avoid painful crises. Moreover, physicians should encourage patients to get immunized for influenza every year.

    Penile implants and other high risk practices in French Guiana’s correctional facility: A cause for concern

    by Marie-Claire Parriault, Amandine Chaponnay, Claire Cropet, Vincent About, Agathe Pastre, Roch Perusseau-Lambert, Mathieu Nacher, Florence Huber

    Prisoners in French Guiana, a French territory located in South America, have a HIV and hepatitis B prevalence of 4%. Body modifications such as penile implants, tattoos, and body piercings are common among detainees, increasing the risk of blood-borne virus transmission. We conducted a cross-sectional randomised survey in which the primary objective was to estimate the prevalence of high risk ‘bloody practices’ (penile implants, tattoos, body piercings) in French Guiana’s only correctional facility. The secondary objective was to describe the risk factors for penile implants, the procedures and motivations for insertion, the reported complications, their risk factors and adverse impact on condom use. Of the 221 male inmates interviewed, 19% had tattoos or body piercings while incarcerated, and 68% had penile implants, of which, 85% had been inserted inside the correctional facility. Addictive behaviors such as cannabis use and alcohol addiction (positive AUDIT-C score), early age at first sexual intercourse, and the number of incarcerations correlated positively with having inserted one or more penile implants while incarcerated. In contrast, having reported previous psychiatric hospitalizations and having a high knowledge score for HIV/AIDS and sexually transmitted infections (STIs) were negatively correlated with the insertion of penile implants while incarcerated. Penile implants were inserted in poor hygienic conditions, usually using the sharp lid of a canned food container, with 18% of early complications, mostly haemorrhage and edema. Condom use was negatively impacted for 52% of men with penile implants. Our results highlight the need for prevention interventions which should aim at increasing knowledge levels and at implementing comprehensive risk-reduction measures.

    Renouncing care in French Guiana: the national health barometer survey

    by Astrid Van Melle, Claire Cropet, Marie-Claire Parriault, Leila Adriouch, Hélène Lamaison, Francine Sasson, Hélène Duplan, Jean-Baptiste Richard, Mathieu Nacher

    In French Guiana, health inequalities are patent for a broad range of pathologies for all age groups. The objective of the present study was to quantify the proportion of the population that had renounced care in the past year, to study predictive factors, and to compare results with other French territories. A two-stage random sample of 2015 individuals aged 15 to 75 years was surveyed by telephone. A descriptive analysis of variables relative to renouncing care, use of health care, screening, and vaccination was initially performed. Multivariate analysis was then used to determine variables associated with renouncing care for financial reasons and renouncing for reasons linked to time were directly estimated using a Poisson model on weighted data. Variables with a significance level < 0.2 in the bivariate analysis were included in the full multivariate model. In French Guiana, during the past 12 months, 30.9% of surveyed persons renounced care whatever the type for financial reasons. Results of the multivariate analysis showed that gender, perceived financial situation, perceived health and complementary insurance status were independent predictive factors of care renouncement for financial reasons. Overall, 24% of the surveyed population declared having renounced to care for time-related motives. The independent predictors for time-related renouncing were different than those for renouncing care for financial reasons: a higher education level and a poor perceived health were independently associated with time-related renouncement; retired persons and students were found to renounce care less frequently than persons with a job. Renouncing for financial reasons, a major target of the 2016 health law, represented a public health problem in French Guiana. Renouncing for lack of time was an important motive for renouncing, which is aggravated by the insufficient number of health professionals, but may benefit from organizational solutions. There are avenues for improvement of health for the most vulnerable: promote health, act on risk factors, and facilitate the readability and accessibility of the health system. Recent reforms to stabilize health insurance may however have some adverse consequences for migrants.

    Factors associated with sexual risk taking behavior by precarious urban migrants in French Guiana

    by August Eubanks, Marie Claire Parriault, Astrid Van Melle, Célia Basurko, Leila Adriouch, Claire Cropet, Mathieu Nacher

    French Guiana is highly affected by HIV. The migrant population is particularly susceptible. The objective of this study was to evaluate the level of risk of HIV transmission and its perception among migrants in French Guiana and to identify predictive factors. An HIV/AIDS Knowledge, Attitudes, Behaviors and Practices study was conducted in 2012 among migrants living in precarious neighborhoods of French Guiana. Of the 1039 participants surveyed, 893 were analyzed, of which 35.6% had risky sex during the past 12 months. Sexual risk taking was higher among the migrant population than in the general population. The predictors of sexual risk taking behavior were: younger age groups, males, having a job, not living with a spouse, having first had sex before age 16, using alcohol or drugs before sex, and having engaged in commercial sex recently. The factors associated with not being aware of one’s risk were: being a woman, being from Guyana or Suriname, non-systematic use of condoms with a regular partner, and never or not recently having been tested for HIV. The results suggest there is still a need for information on HIV risks in a highly vulnerable population.


  • Sexual risk behaviors and predictors of inconsistent condom use among crack cocaine users in the French overseas territories in the Americas

    by Marie-Claire Parriault, Astrid Van-Melle, Célia Basurko, Larissa Valmy, Bruno Hoen, André Cabié, Marie-Thérèse Goerger-Sow, Mathieu Nacher

    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.

    Prevalence and predictive factors for renouncing medical care in poor populations of Cayenne, French Guiana

    by Larissa Valmy, Barbara Gontier, Marie Claire Parriault, Astrid Van Melle, Thomas Pavlovsky, Célia Basurko, Claire Grenier, Maylis Douine, Antoine Adenis, Mathieu Nacher

    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. The study was cross sectional. It focused on knowledge, attitudes, practices and beliefs of the population living in poor neighborhoods of the Cayenne area. 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. 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. 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.


  • Predictive factors of unprotected sex for female sex workers: first study in French Guiana, the French territory with the highest HIV prevalence

    by Marie-Claire Parriault, Célia Basurko, Astrid Van Melle, Emilie Gaubert-Maréchal, Stéphanie Rogier, Pierre Couppié, Mathieu Nacher

    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, and 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.
