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

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. 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.

A prospective matched study on symptomatic dengue in pregnancy.

Dengue fever is an increasing problem worldwide, but consequences during pregnancy remain unclear. Much of the available literature suffers from methodological biases that compromise the validity of clinical recommendations. We conducted a matched cohort study during an epidemic in French Guiana to compare events and pregnancy outcomes between two paired groups of pregnant women: women having presented with symptomatic dengue during pregnancy (n = 73) and women having had neither fever nor dengue during pregnancy (n = 219). Women in each arm were matched by place of follow up, gestation weeks at inclusion, and place of residence. Dengue infection was considered to be confirmed if viral RNA, N S1 antigen, the seroconversion of IgM antibodies or the presence of IgM was detected in collected samples. According to the 2009 WHO classification, 27% of the women with symptomatic dengue had at least one clinical or biological warning sign. These complications occurred after the 28th week of gestation in 55% of cases. The medical history, socioeconomic status and demographic characteristics were included in multivariate analysis. Exposure to dengue during pregnancy was not significantly associated with prematurity, small for gestational age infants, hypertension or emergency caesarian section. Maternal dengue with warning signs was a risk factor for peripartum hemorrhage with adjusted relative risk = 8.6(95% CI = 1.2-62). There was a near significant association between dengue and in utero death (p = 0.09). This prospective comparative study underlined the importance of taking into account potential confounders between exposure to dengue and the occurrence of obstetrical events. It also confirms the need for increased vigilance for pregnant women with dengue, particularly for women who present with severe dengue.

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

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.
