RESUMEN

BACKGROUND: Four large community-randomized trials examining universal testing and treatment (UTT) to reduce HIV transmission were conducted between 2012-2018 in Botswana, Kenya, Uganda, Zambia and South Africa. In 2014, the UNAIDS 90-90-90 targets were adopted as a useful metric to monitor coverage. We systematically review the approaches used by the trials to measure intervention delivery, and estimate coverage against the 90-90-90 targets. We aim to provide in-depth understanding of the background contexts and complexities that affect estimation of population-level coverage related to the 90-90-90 targets. METHODS: Estimates were based predominantly on "process" data obtained during delivery of the interventions which included a combination of home-based and community-based services. Cascade coverage data included routine electronic health records, self-reported data, survey data, and active ascertainment of HIV viral load measurements in the field. RESULTS: The estimated total adult populations of trial intervention communities included in this study ranged from 4,290 (TasP) to 142,250 (Zambian PopART Arm-B). The estimated total numbers of PLHIV ranged from 1,283 (TasP) to 20,541 (Zambian PopART Arm-B). By the end of intervention delivery, the first-90 target (knowledge of HIV status among all PLHIV) was met by all the trials (89.2%-94.0%). Three of the four trials also achieved the second- and third-90 targets, and viral suppression in BCPP and SEARCH exceeded the UNAIDS target of 73%, while viral suppression in the Zambian PopART Arm-A and B communities was within a small margin (~ 3%) of the target. CONCLUSIONS: All four UTT trials aimed to implement wide-scale testing and treatment for HIV prevention at population level and showed substantial increases in testing and treatment for HIV in the intervention communities. This study has not uncovered any one estimation approach which is superior, rather that several approaches are available and researchers or policy makers seeking to measure coverage should reflect on background contexts and complexities that affect estimation of population-level coverage in their specific settings. All four trials surpassed UNAIDS targets for universal testing in their intervention communities ahead of the 2020 milestone. All but one of the trials also achieved the 90-90 targets for treatment and viral suppression. UTT is a realistic option to achieve 95-95-95 by 2030 and fast-track the end of the HIV epidemic.

RESUMEN

With 2.9% of HIV prevalence in the general population, Côte d'Ivoire is one of the countries most affected by the HIV epidemic in West Africa. In this country, only 63% of people infected with HIV are aware of their status. A cross-sectional phone survey was conducted with a representative sample of 3,867 individuals to describe the practices and factors associated with a recent HIV testing (≤ 1 year) in Côte d'Ivoire. Data relative to the last done HIV test as well as the socio-demographic characteristics, sexual behavior, access to information, perceptions, capacities and autonomy as well as social and geographical environment of the participants were collected. Logistical regression models were used to identify the associated factors with a recent HIV test (≤ 1 year). Lack of information is one of the main barriers to HIV testing (only 60% of individuals know a place to get tested). For men, despite the fact that HIV testing is free of charge, poor economic conditions seem to be a barrier to testing. The social environment, including peer influence, also appears to have an effect on testing among men. For women, testing is associated with their perceptions of HIV exposure. There is a need to rethink the current HIV testing communication in Côte d'Ivoire and to identify economic or social incentives to remove access barriers to HIV testing.


Avec 2,9 % de sa population infectée par le VIH, la Côte d'Ivoire fait partie des pays d'Afrique de l'Ouest les plus touchés par l'épidémie à VIH. On estime que seules 63 % des personnes infectées par le VIH connaissent leur statut. Une enquête transversale, par téléphone, a été réalisée auprès d'un échantillon représentatif de 3 867 personnes afin de décrire les pratiques et les facteurs associés à la réalisation récente (≤ 1 an) d'un dépistage du VIH en Côte d'Ivoire. Les données collectées concernaient le dernier test réalisé ainsi que les caractéristiques sociodémographiques, comportements sexuels, accès à l'information, perceptions, capacités, autonomies ainsi que l'environnement social et géographique des participants. Des modèles de régression logistique ont été réalisés afin d'identifier les facteurs associés à la réalisation récente d'un test du VIH (≤ 1 an). Le manque d'information est l'un des principaux freins au dépistage (seuls 60 % des individus connaissent un lieu où réaliser un test). Chez les hommes, malgré la gratuité du dépistage, une faible condition économique semble être un frein à la réalisation d'un test. L'environnement social, notamment l'influence des pairs, semble aussi avoir un effet sur le recours au dépistage chez les hommes. Chez les femmes, le dépistage est associé à leurs perceptions d'exposition au VIH. L'offre de dépistage actuelle en Côte d'Ivoire nécessite de repenser la communication autour du test ainsi que d'identifier des incitatifs économiques ou sociaux permettant de lever les freins au dépistage.

RESUMEN

The purpose of this paper is to identify which Provider-Initiated HIV Testing and Counseling (PITC) organizational models are the most efficient to maximize testing coverage. We conducted a systematic literature review to identify published articles that evaluated routine PITC programs implemented in adult health facilities in Sub-Saharan Africa. We considered only articles measuring PITC offer, PITC acceptability and PITC coverage. Adjusted meta-regression models were performed to measure the association between PITC offer, acceptability and coverage with PITC organizational model. A total of 30 articles were included in the meta-analysis. Overall, 85.4% [95%CI: 77.2-93.5] of patients were offered a test, and 87.1% [82.4-91.7] accepted the test resulting in a PITC coverage of 74.3% [66-82.6]. Four types of PITC organizational models were identified: PITC initiated and performed during the consultation (model A), PITC initiated before consultation (model B), PITC referred on-site (model C) and PITC referred off-site (model D). Compared to model A, model B had a similar coverage (aOR: 1.02 [0.82-1.26]). However, coverage was lower for model C (aOR: 0.81 [0.68-0.97]) and model D (aOR: 0.58 [0.44-0.77]). Initiating the testing process before or during medical consultation is recommended for maximizing testing coverage among patients.

RESUMEN

Since the early 2010s, the President's Emergency Plan for AIDS Relief (Pepfar) and the Global Fund to Fight AIDS, Tuberculosis and Malaria have stiffened their result-based management strategies. Disbursement conditions are increasingly demanding for funded NGOs (achievement of quantified objectives, frequent reporting, and monitoring of activities), and their remuneration depends on the results achieved. This article aims to analyze the effects of this strengthening of policies based on New Public Management on local implementation of activities, based on the example of community-based HIV testing. In three health districts of Côte d'Ivoire, in 2015 and 2016, we mapped the actors involved in community-based HIV testing and conducted semi-directive interviews with members of the community-based NGOs (n = 18). The funding of local HIV testing organizations is channeled through intermediary organizations according to a complex pyramid system. This, combined with cumbersome activity reporting and data validation, results in delays in the disbursement of funds and significantly reduces the actual time available to implement activities, i.e., to less than half the time planned for this purpose. This managerialization -of both Pepfar and the Global Fund - produces the counterproductive effects against which it was supposed to fight.

RESUMEN

BACKGROUND: In Ivory Coast, little is known about health needs and health access barriers among young people. The aim of this study was to describe health provision, health needs and barriers when seeking medical care, with an emphasis on sexual and reproductive health, and the acceptability of a medical examination for students attending their first year at the Houphouët-Boigny University, Abidjan, Ivory Coast. METHODS: We conducted a representative cross-sectional study among second year students who were selected by two-stage equiprobable random sampling. In-depth interviews were conducted among students and the university health center staff. RESULTS: Five hundred and forty three students (322 men and 221 women) answered a questionnaire (participation rate 98.4%). Among women who ever had sex, 38.4% (95%CI [30.5%-47.0%]) had unmet contraception needs and 31.2% [23.7%-40.0%] had experienced an unwanted pregnancy. Fear about impaired fertility was the leading reason for non-use of hormonal contraception, the method of choice among most students. The main health problems among students, by order of frequency were malaria (54.3%), respiratory infection (44.6%), constipation (28.0%) and psychological problems (25.9%). High cost perception of services offered, despite their gratuity, were the main barriers against access to the university health center, indicating a lack of communication about this structure and its services. The majority of students favored the establishment of a medical examination during the first year at the university. CONCLUSION: Establishing a medical examination would improve health center visibility. The following services could be offered: (i) HIV, chlamydia and gonorrhea screening, (ii) hepatitis B virus screening and vaccination, (iii) provision and information about contraceptive methods, (iv) presentation of the university health center services. Dedicated spaces where students could have access to information about health-related topics (e.g. sexuality, nutrition, depression) could complete the university's healthcare offer.

RESUMEN

BACKGROUND: Like many African countries, the issue of sex between men in Burkina Faso remains taboo and sometimes result in social exclusion. This population which is vulnerable to HIV/AIDS is unknown, due to lack of scientific researches. AIM: Our study aimed to characterize knowledge, attitudes and sexual practices and to estimate HIV seroprevalence among men having sex with men (MSM) living in Ouagadougou. METHODS: A cross-sectional study was conducted in order to describe and analyze MSM living in Ouagadougou. They were recruited by snowball sampling, aged at least 18 years, and accepted to participate at the study. Data were collected by qualified interviewers through administered questionnaire face to face. HIV test was systematically proposed. RESULTS: A total of 142 MSM were recruited during the study period. The sample was mostly composed of students or pupils (60.8%), single men (91%), with age range 18-30 years (96.5%). The HIV knowledge median score was 8/10. HIV seroprevalence was 8.9% (4.5-15.4). CONCLUSION: Our study confirms the vulnerability of MSM living in Ouagadougou about HIV/AIDS given the high rate of HIV seroprevalence. Targeted interventions for prevention, care and scientific research are challenges for the authorities to sustain the achievements of the national fight against HIV and AIDS.

RESUMEN

OBJECTIVES: Research on men who have sex with men (MSM) in sub-Saharan Africa was neglected for a long time. The objective of this study was to understand factors associated with unprotected anal intercourse (UAI) with male partners among a group of MSM living in the city of Douala, Cameroon. METHODS: In 2008, a survey on the sexual activity and practices of MSM was set up in Douala in collaboration with a local community-based organisation. Data were collected among a convenience sample of 168 MSM during face-to-face interviews with trained interviewers. RESULTS: A total of 142 individuals reported sexual activity during the previous 6 months, among whom 80 (57%) reported UAI with male partners. In a multivariate logistic regression model adjusted for the frequency of sexual intercourse, not having had access to prevention interventions and not knowing any HIV-infected person were both independently associated with a higher risk of UAI. Other factors associated with this higher risk included having had a stable male partnership at some point in one's life and not having been out of Douala for more than 4 weeks during the previous year. CONCLUSIONS: This community-based research is the first study of MSM in Cameroon and the HIV transmission risks they face. Results show the importance of HIV prevention interventions from peers, and underline the need to maintain efforts to develop specific interventions targeting MSM more efficiently in the African context.
