You can’t eat the sweet with the paper on : An anthropological study of perceptions of HIV and HIV prevention among Xhosa youth in Cape Town, South Africa

Yllequist, Kajsa January 2018 (has links)
South Africa has the biggest HIV epidemic in the world and the HIV rates among youth are especially alarming. In 2016 there were 110 000 new cases of HIV among 15 to 24-year-olds. The aim of this study is to describe and analyse perceptions of HIV and HIV prevention among Xhosa youth in the township of Langa, Cape Town. In order to study this, I focus on the organisation loveLife and their employed peer educators called groundBREAKERs (gBs). To gain knowledge on what fuels the HIV epidemic in this setting I will examine their thoughts and notions of HIV/AIDS, sexuality and sexual behaviour in relation to the information that is available to them. Examining the socio-cultural context of HIV/AIDS is important to understand the spread and why HIV is not declining sufficiently in response to HIV preventative efforts. This thesis is based on ten weeks of fieldwork at loveLife’s Y-Centre in Langa. The material was gathered through semi-structured interviews and participant observation. To analyse the drivers for the spread of HIV among Xhosa youth an analytical tool of gender roles, with a main focus on masculinity, has been utilized.

Prise en charge des travailleuses du sexe confrontées au VIH/sida au Burkina Faso : évaluation d’un paquet d’intervention offert aux jeunes travailleuses du sexe dans la ville de Ouagadougou / HIV prevention and care services for female sex workers : efficacy of a community-based intervention package among young female sex workers in Ouagadougou (Burkina Faso)

Traore, Isidore Tiandiogo 02 December 2015 (has links)
Contexte: Les travailleuses du sexe (TS) sont un groupe à risque de l’infection à VIH, jouant un rôle majeur dans la dynamique de l’épidémie en Afrique de l’Ouest. Les interventions de prévention et de prise en charge du VIH ciblant ces femmes sont donc indispensables, mais leur contenu reste à définir. Nous avons conçu un paquet d’intervention qui combinait la prévention et les soins, et estimé son impact sur l’incidence du VIH. Méthodes: Entre septembre 2009 et septembre 2010, nous avons réalisé une étude transversale à Ouagadougou (Burkina Faso) suivie d’une étude de cohorte interventionnelle chez des jeunes TS âgées de 18 à 25 ans, avec un suivi trimestriel pendant 21 mois maximum. Le paquet d’intervention de la cohorte combinait des activités de prévention effectuées par des pairs (sessions de communication pour un changement de comportement) et de soins (IST, VIH, soins généraux, santé sexuelle et reproductive, soutien psychologique).A chaque visite, les comportements sexuels étaient collectés par un questionnaire ; des tests VIH, HSV-2 et de grossesses étaient réalisés. L’incidence de l’infection à VIH observée dans la cohorte a été comparée à l’incidence attendue en absence d’intervention. Cette dernière a été estimée grâce à un modèle mathématique de Bernouilli utilisant les données collectées chez les clients des TS, et des estimations de paramètres clés issus de la littérature.Durant le suivi, nous avons défini un comportement à risque comme le premier épisode d’un évènement biologique résultant d’un rapport sexuel non-protégé : grossesse non-désirée, primo-infection HSV-2 ou à T. vaginalis. Nous avons utilisé un modèle logistique à effet aléatoire pour identifier les déterminants de ces comportements à risque durant le suivi.Résultats: Parmi les 609 travailleuses du sexe pré-sélectionnées dont 188 (30,9%) professionnelles, la prévalence du VIH était de 10,3% chez les professionnelles et 6,5% chez les non-professionnelles l’âge médian était de 21 ans. Au total, 41,2% des professionnelles et 47,5% des non-professionnelles rapportaient une utilisation non systématique du préservatif, principalement avec leurs partenaires réguliers.Dans cette étude transversale, l’infection à VIH était associée à l’âge (aOR=1,44; IC95%: 1,22-1,71), la vie en couple (AOR=2,70; IC95%: 1,21-6,04), et l’infection à T. vaginalis (aOR=9,63; IC95%: 2,93-31,59), tandis que la réalisation antérieure d’un test VIH réduisait nettement ce risque (AOR=0,18; IC95%: 0,08-0,40). Les 321 TS non-infectées par le VIH incluses dans la cohorte ont effectué un suivi total de 409 personne-années (p-a). Aucune participante n’a fait une séroconversion au VIH durant le suivi (0/409 p-a) alors que l’incidence attendue modélisée était de 5,05/409 p-a (IC95%, 5,01-5,08) soit 1,23 infection/100 p-a (p=0,005). Cette incidence nulle était associée à une réduction du nombre de partenaires réguliers et de clients réguliers ainsi qu’à une augmentation du taux d’utilisation constante du préservatif avec les nouveaux clients (aOR =2,19; IC95%, 1,16-4,14) et avec les clients réguliers (aOR=2,18; IC95%, 1,26-3,76). Cependant, les comportements à risque restaient élevés durant l’intervention : 26,7/100 p-a (IC95%, 24,1-33,7). Ce risque résiduel était plus élevé chez les TS vivant en couple (aOR =7,47, IC95%, 1,70-30,80) et chez les non-professionnelles (AOR =5,53, IC95%, 1,75-16,84). Ces dernières avaient le plus tendance à ne pas déclarer les comportements à risque lors des interviews. Conclusions: Notre étude a démontré la nécessité de cibler les jeunes TS par des interventions adaptées.Notre paquet d’intervention combinant la prévention du VIH et les soins a permis de réduire l’incidence du VIH chez les jeunes travailleuses du sexe au Burkina Faso. Les interventions devront se focaliser sur le dépistage du VIH, les TS non-professionnelles et les partenaires réguliers. / Background: In West Africa, interventions targeting female sex workers (FSW) are crucial to impact on the HIV dynamics. However, the contents and efficacy of these interventions are unclear, and identifying the most at risk FSW in order to adapt these interventions remain challenging, partly because of the limitations of self-reported sexual behaviours. We therefore designed a comprehensive dedicated intervention targeting young female sex workers, and assessed its impact on HIV incidence in Burkina Faso and the reliability of interview data. Methods: From September 2009 to September 2010 we conducted a cross sectional study in Ouagadougou, Burkina Faso. Then HIV-uninfected FSW aged 18-25 years were enrolled in a prospective interventional cohort. The participants were followed quarterly for a maximum of 21 months. The intervention group received a package which combined prevention and care within the same setting, and consisting of peer-led education sessions, psychological support, sexually transmitted infections and HIV care, general routine health care, and reproductive health services. At each visit, behavioural characteristics were collected and HIV, HSV-2 and pregnancy were tested. High-risk behaviour was defined as the first occurrence of any biological event resulting from unsafe sex, including unexpected pregnancy or HSV-2 or T. vaginalis infection. We used random logistic models to assess the relationship between socio-demographic characteristics and the residual high risk behaviours during the intervention.We compared the cohort HIV incidence with a Bernoulli modelled expected incidence in the absence of intervention, using data collected at the same time from FSW clients and key parameters from the litterature. Results: We screened 609 FSW including 188 (30.9%) professionals. Their median age was 21 years [IQR, 19-23], and the prevalence of HIV was 10.3% among professionals and 6.5% among non-professionals. Overall, 277 (45.6%) women reported high-risk behaviours (41.2% among professionals and 47.5% among non-professionals), which were driven mainly by non-consistent condom use with regular partners. In multivariable analysis, before the intervention, HIV infection was associated with older age (AOR=1.44; 95%CI: 1.22-1.71), with being married/cohabiting (AOR=2.70; 95%CI: 1.21-6.04), and with T. vaginalis infection (AOR=9.63; 95%CI: 2.93-31.59), while previous HIV testing was associated with a decreased risk (AOR=0.18; 95%CI: 0.08-0.40).The 321 HIV-uninfected FSW enrolled in the cohort completed 409 person-years of follow-up. No participant seroconverted for HIV during the study while the expected modelled number of HIV infections were 5.05 (95%CI, 5.01-5.08) during the same follow-up (409 person-years) or 1.23 infection per 100 person-years (p=0.005). This null incidence was related to a reduction in the number of regular partners and regular clients, and to an increase in consistent condom use with casual clients (AOR =2.19; 95%CI, 1.16-4.14, p=0.01) and with regular clients (AOR=2.18; 95%CI, 1.26-3.76, p=0.005). However, the incidence of residual risk was high, at 26.7/100 person-years (95% CI, 24.1-33.7). The residual risk was higher among FSW living in couple (adjusted odd ratio [AOR] =7.47, 95% CI, 1.70-30.80) and among those for whom sex work was not the main source of income (AOR =5.53, 95% CI, 1.75-16.84). The latter also tended not to report high-risk behaviours during face –to–face interview. Conclusions: This study highlights the need for targeted interventions among young FSW focusing particularly on non-professionals, sexual behaviours with regular partners and regular HIV testing. The ANRS 1222 study intervention package which combined peer-based prevention and care within the same setting markedly reduced HIV incidence among young female sex workers in Burkina Faso, through reduced risky behaviours.

An understanding of HIV and AIDS discourses of teachers in Cape Town, South Africa, and its' relevance for HIV prevention in schools

Davids, Mogamat Noor January 2010 (has links)
Philosophiae Doctor - PhD / This study investigates the content and nature of the HIV and AIDS "discourses" of teachers, which I have identified as a knowledge gap in the existing HIV and AIDS education literature that, presumably, is informing practice. The argument is that, without an understanding of teachers' HIV and AIDS discourses, we will continue to speculate about why HIV education often does not have the effect we expect of it - reduced HIV infection, reduced risk behaviour, reduced teenage pregnancies - and why it has been regarded as a failure by many. The public media often expose rampant teenage sexual behaviour, such as abortions, pregnancies, and an addiction for electronically generated pornographic materials, causing consternation and sending shockwaves through schools and society. These reports attest to the kind of risky sexual behavior which makes children vulnerable to HIV infection. In spite of more than twenty years of HIV and AIDS education, teachers and society at large remain uncertain and uncomfortable about teenage sexual behavior, HIV infection and the inability of adults to protect young people from sexual exploitation. / South Africa

Use of modified respondent driven sampling methodology to enhance identification and recruitment of most at risk persons into an HIV prevention trial in Kisumu, Western Kenya

Otieno, Fredrick Odhiambo January 2016 (has links)
Philosophiae Doctor - PhD / This thesis presents research on the use of modified respondent driven sampling (mRDS) methodology to enhance identification and recruitment of key populations (KP) into an HIV prevention trial in Kisumu, western Kenya through a three phase mixed method study. The study was carried out in Kisumu, western Kenya within the Kenya Medical Research Institute (KEMRI) and the US Centers for Disease Control and Prevention (CDC) Research and Public Health Collaboration platform. The three phases included: 1. PHASE I: Identification and determination of categories of KPs and techniques of locating and motivating them to participate in HIV prevention trials.2. PHASE II: Design and Implementation of a mRDS methodology in recruiting Ks into HIV prevention trials.3. PHASE III: Evaluation of the mRDS in recruitment of KPs into an HIV incidence cohort study. Methods Phase I of the study included the conduct of in depth interviews which were used to identify different categories of persons considered to be KPs within Kisumu, identify strategies of locating the KPs and determine motivators and inhibitors of KPs participation in HIV prevention trials. Phase II on the other hand included the administration of a survey that had been refined in Phase I. The survey was used to design a mRDS methodology which was then implemented to recruit KPs into the survey. Phase III evaluated the success of the mRDS in recruiting KPs into an HIV prevention study by assessing the risk profiles for participants screened and enrolled into the Phase III study. Ethical approval for the study was sought from the ethics committee of the Kenya Medical Research Institute, the US CDC and the University of the Western Cape.The study recruited 53 individuals into phase I and was able to 8 identify different categories of people considered to be KPs and the 4 salient strategies that could be used to recruit them into HIV prevention studies. The phase also identified 8 potential motivators and 9 potential inhibitors to participation in HIV prevention research. These categories and salient strategies were used in phase II to develop and pilot a mRDS methodology in recruiting 203 individuals into a survey. The survey was used as a validation tool for the risk levels of persons recruited by the mRDS using the variables of inconsistent condom use and having multiple partners. The validated mRDS was then applied in the recruitment of 1,292 participants in phase III of thestudy. These study participants had characteristics similar to those seen in similar studies and elucidated from phases I and II of the study. HIV seropositivity was used as the variable for validating risk levels of participants in this study and this was found to be higher that that seen in general population and comparable to that seen in other KPs groups in the region. Results: Overall the study was able to identify different categories of people considered to be at high riskof HIV acquisition. The groups identified included people who frequent bars (e.g. bar workers, drunkards, sex workers, businessmen), people who work in transportation (e.g. truck drivers, matatu drivers, motorcycle drivers, taxi drivers, bicycle taxi drivers), fishermen/fishmongers, MSM and hair salon workers. The study also identified using personal contact, link persons, peer mobilisers and leaders as strategies of identifying and locating KPs. The study used the mRDS successfully in recruiting participants with evaluation of inconsistent condom use and multiple sexual partnerships showing the participants to be of high risk behaviour. Of all the females in the study, only 3.3% were pregnant. The prevalence of Chlamydia was 2.9%, gonorrhoea was 5.0%, syphilis was 0.4% and HSV-2 was 46.0%. Those who tested positive for HIV were 26.2% with 42.3% of the HIV positive participants having CD4 counts of between 250 – 500 cells/ml. Recommendations and Conclusion:The mRDS was successful in recruiting KPs in an HIV prevention trial. Majority of the participants reported inconsistent condom use and having multiple sex partners. In addition to MSM, SW and transport industry workers, fisherfolk, discordant couples, widowers, street youth, car washers and police also form part of KPs groups. The HIV prevalence was higher amongst these groups compared to general population with discordant couples having the highest HIV prevalence. The study recommends that mRDS should be used to identify and recruit KPs as it not only allows for faster recruitment of KPs, it also reduces the expense and complexity associated with coupon management in the standard RDS.

The barriers and enabling factors for the uptake of voluntary medical male circumcision among "Coloured" males between the ages of 15 and 49 years in the Cape Town Metropolitan Municipality

Cockburn, Jonathan January 2016 (has links)
Magister Public Health - MPH / Voluntary Medical Male Circumcision (VMMC) has been proven to reduce heterosexual HIV transmission to men by approximately 60%. It has been argued that achieving 80% circumcision coverage among males aged 15–49 years within five years and maintaining this coverage rate in subsequent years, could avert 3.4 million new HIV infections within 15 years and generate treatment and care savings of US$16.5 billion. As a result the South African Government plans to circumcise 4.3 million males aged 15 and 49 years by the 2015/2016 financial year. However, in the Western Cape the uptake for circumcision has been poor. While there is not a great deal of knowledge out there about the reasons for the uptake (or lack thereof) of VMMC in the Western Cape, current research focus on Xhosa males predominantly. However, there is limited research on circumcision among the "Coloured" population of the Western Cape. As the "Coloured" population is the largest group in the Western Cape, this gap in research and knowledge is worth noting. The current study aimed to explore the barriers to and enablers of uptake of VMMC among "Coloured" males between the ages of 15 and 49 years in the Cape Town Metropolitan Municipality. Methodology: The study adopted a qualitative design; semi-structured interviews were conducted with seven key informants, and two focus group discussions with men who had undergone VMMC and men who had chosen not to volunteer to undergo VMMC. Thematic analysis was used to analyse the data. Results: The key enablers to uptake of VMMC were: the desire for improved hygiene; the reduction in the risk of contracting other STIs; the reduction in the risk of contracting HIV; the role of partners and family members who can encourage males to access services; the perceived improvement in the males' sexual experience and performance; and cultural reasons and religious injunction. On the other hand the key barriers that discouraged "Coloured" participants from accessing the services include: fear, particularly the fear of pain; the experience of the health services and the role of health staff; the six week healing period in which males cannot have sex; the unwillingness to alter the body that they were born with; role of partners and family as discouragers of uptake; the influence of gangsterism on the ability of males to access services offered on a different gang's 'turf'; and, substance abuse. The recommendations in this study focus largely on the need to expand the coverage of VMMC in the Cape Town Metropolitan Municipality and to increase the uptake among "Coloured" males between the ages of 15 and 49 years. . These recommendations essentially involve the need to break down the barriers and to accentuate the enablers. To this end social mobilisation campaigns should not focus solely on HIV prevention but rather on hygiene and improved sexual experience and appearance as well as the cultural and religious aspects. With regard to the barriers it is essential that any social mobilisation engages with the fear of pain. On method to do this would be through the introduction and expansion of the PrePex™ device. The fear that circumcision could impact on sexual performance and the fear of embarrassment and discomfort the whole process would potentially bring would need to be allayed. In addition it is essential that the health services and health staff are orientated and trained in a way that ensures that the process of circumcision is as easy as possible for the clients. / National Research Foundation

The effect of a sports-based HIVv prevention programme on HIV risk related behaviours among high school learners

Wasiu, Awotidebe Adedapo January 2012 (has links)
Philosophiae Doctor - PhD / Background: The Human Immunodeficiency virus (HIV) has become a global public health challenge amid the growing concern of adolescent risky sexual behaviour, influenced by biological and psycho-social factors. There is an increasing demand for adolescent sexual risk reduction interventions, especially in sub-Saharan Africa which remains the hub of HIV epidemic worldwide. Sport-based HIV prevention programme has been identified as one of the interventions, in addition to other approaches to provide young people with appropriate HIV knowledge and skills to either delay or reduce risk-taking behaviour. Despite the potential of sport-based programme for sexual risk reduction, there is limited information on how to adapt it to meet adolescent needs in terms of design, contents, and delivery. This information is necessary to provide sufficiently strong evidence to support widespread implementation of sport-based programme, especially in rural African schools. Therefore, the study aimed to measure the impact of a sport-based HIV prevention intervention in the reduction of HIV related sexual risk behaviour among rural high school learners aged 13-18. Method: The overall study design was a concurrent mixed method, utilizing both the quantitative and qualitative approach. The population for the quantitative and the qualitative studies was made up of two high schools in a predominantly “Coloured” community in Ceres. Two classes each were randomly selected from grades 8-10 in both intervention and control school. The intervention was developed through a process of focus group discussions with the Grassroot Soccer (GRS) staff and it was guided by the Social Cognitive Theory. The intervention was delivered to grade 8-10 learners by GRS peer facilitators using the GRS generation skillz curriculum that consists of 12-week sessions in the intervention school. Quantitative data were analysed with multivariate statistical techniques and qualitative data with thematic analysis approach. Results: The data that assessed the behavioural and protective factors to understand why learners in rural schools engage in risky sexual behaviour showed that about 27.2% of the learners reported being sexually active. Of the sexually active learners, 48.7% reported engaging in sex by 14 years or younger and nearly 42.2% reported multiple sexual partners with significant higher proportion of boys than girls. Nearly 55.2% of the sexually active learners reported irregular condom use and 46.3% did not use a condom at the last sexual encounter. The majority of the learners (87%) did not know their HIV status. Being male (OR = 6.60;95% C I = 1.62 – 26.84) and peer influence (OR = 3.01; 95% CI = 1.97-4.60) were the strongest predictors of reporting sexual intercourse and early sexual activities before the age 15 respectively. Though the knowledge of HIV was low, those with greater knowledge of HIV were more likely to use a condom at last the sexual encounter (OR = 1.22; 95% C I =1.03-1.44). The learners who participated in sport-based intervention were 1.43times likely to report higher self-efficacy to refuse sex compared to the control group (OR = 1.43; 95% C.I =1.07-1.92).The process evaluation indicated that the sport-based intervention was well received among the learners as it gave them free space to freely express themselves. Conclusion: The findings have shown that sport-based intervention can be successfully implemented in school and is a promising approach to reduce risks associated with risky sexual behaviour in learners. However, the quality of the programme delivery was hampered by irregular session‟s schedule and language of instruction. The process suggests for a longer exposure period and because of social-cultural diversity, learners must be provided with the ownership of the programme in schools.

Conseil prénatal du VIH orienté vers le couple : faisabilité et effets sur la prévention du VIH au Cameroun / Couple-oriented prenatal HIV counseling : feasibility and effects on HIV prevention in Cameroon

Tchendjou tankam, Patrice Yves 17 December 2014 (has links)
Cette intervention a été construite par la méthode du « health belief model », en renforçant l’intervention de conseil post-test classiquement offerte au cours du dépistage prénatal du VIH, en prenant en compte le contexte conjugal de la femme. Une approche méthodologique en deux étapes a été adoptée. La première étape, encore appelée étape de preuve de concept, a consisté, à travers un essai d’intervention randomisé mené dans une structure de référence en zone urbaine (essai ANRS 12127- Prenahtest), à évaluer l’efficacité de la nouvelle intervention de COC pour améliorer le dépistage prénatal du VIH des partenaires, le conseil de couple de VIH, la communication conjugale autour du VIH. Outre les effets du COC, nous avons aussi documenté les autres facteurs associés à l’approche de couple de prévention du VIH. La deuxième étape a consisté en une phase de passage à l’échelle de la mise en oeuvre de l’intervention de COC, de façon à évaluer sa transférabilité dans la pratique des soins courants. A cet effet, une étude de type Avant/Après (le projet SIMECAM-FGSK) a été réalisée. Ce choix méthodologique a permis de prendre en compte l’architecture sanitaire du système de santé, en incluant le niveau périphérique qui comporte trois catégories de formations sanitaires (hôpital de district ; centre médical d’arrondissement ; centre de santé intégré). Il a aussi permis de prendre en compte les contraintes éthiques, liées à la connaissance de la supériorité de la nouvelle intervention de COC décrite en zone urbaine. Les résultats les plus importants de l’essai ANRS 12127/12236l en zone urbaine au Cameroun sont les suivants :- La réalisation d’un essai comparatif randomisé de puissance moyenne et sans biais majeur et qui a été bien mené jusqu’à la fin - La description de l’acceptabilité du conseil orienté vers le couple dans un contexte où la prévalence du VIH atteint les 12% ;- La description de l’efficacité du nouveau type de conseil orienté vers le couple pour améliorer en zone urbaine la fréquence du dépistage du VIH du partenaire jusqu’à atteindre 27% des femmes ayant reçu le COC (vs 16% pour les femmes du groupe classique) ; - La description de l’efficacité du nouveau type de conseil pour améliorer la fréquence du conseil et dépistage du VIH en couple autour de 13% des femmes ayant reçu le COC (vs 3% pour les femmes du groupe classique) ;- La description de l’efficacité du nouveau type de conseil pour améliorer la fréquence de la communication conjugale autour du VIH. En zone rurale, les principaux résultats préliminaires du projet SIMECAM-FGSK, après seulement six mois effectifs d’activités de passage à l’échelle sont : - Le taux de prévalence du VIH est de 20,5% ; - Le COC permet le dépistage du VIH de près de 18% des partenaires ; et ce dépistage est majoritairement effectué dans le cadre d’un conseil VIH en couple ; - Le taux de prévalence du VIH chez les partenaires est de 22% et 11,2% des couples sont sérodiscordants ; - Sur cinquante trois femmes dépistées positives pour le VIH, 94% ont bénéficié d’une prise en charge par les ARV pour la PTME, dont 28,3% suivant le protocole de l’option B+. Le travail réalisé dans le cadre de cette thèse a permis de montrer que les effets du COC sur l’approche de prévention du VIH en couple sont modestes mais réels. Les faibles proportions observées peuvent entre autres s’expliquer par un certain nombre de barrières individuelles (telles que la peur de découvrir son statut VIH en même temps que sa partenaire), de barrières programmatiques (telles que les délais d’attente et la qualité de l’accueil des hommes en prénatale), et des barrières culturelles (la considération de la prénatale comme un espace réservé aux femmes). Par ailleurs, il est important de relever un certain de limites au cours de ce travail de thèse. L’essai Prenahtest compte un taux de perdues de vue de près de 25%, ce qui ne permet pas d’exclure tous les biais. / It is a little above 30 years that the first cases of AIDS resulting from HIV infection were described in the United States of America. This disease remains a public health problem worldwide, with a great social and economic impact. In 2012, it was reported that the disease had already caused over 25 million deaths, and yet every year, more than 70% of the 2.3 million new HIV infections occurred in Africa, where there are only 12% of the world’s population. In Africa, there is a peculiar evolution of this infection overtime. After nearly two decades of promoting the ABC programs (abstinence, be faithful, condoms); promotion of counseling and testing; or more recently, introduction of pre- and post-exposure prophylaxis, usage of antiretroviral therapy as treatment and prevention, the prevalence of HIV remained stable or decreased in the most at-risk populations but increased dramatically in the formerly low-risk populations. Recent data from South Africa, Botswana an Cameroon showed that the prevalence of HIV is twice as much in women as in men and was higher in the population age range of 30 to 45 years, which constitute the economic livelihood of the continent. Furthermore, in some countries like in Cameroon, HIV prevalence was reported to be higher in stable couples (married, prolonged cohabitation etc.). It therefore seems necessary to revise the actual strategies of HIV prevention to deal with the new facet of the HIV epidemic in the African context. This thesis, which is a reported experience from an operational research, presents the results of the evaluation of a new intervention so called couple-oriented HIV counseling (COC), built by using the health belief model. It is an enhanced HIV post-test counseling offered during prenatal HIV testing, in replacement of the classical HIV post-test counseling. The originality of this study was the quality of our study design with a good level of proof and the public health perspective of the new strategy. To realize the study, we adopted two methodological approaches. The first one, acting as a proof of concept, was a randomized trial, conducted in a reference structure in an urban area (ANRS 12127-Prenahtest trial), to evaluate the efficiency of the new COC intervention to improve prenatal HIV testing of male partners, couple counseling for HIV and spousal communication about. Besides the effects of the COC, we documented other conditions for the improvement of previously mentioned indicators. After the proof of concept phase, we realized a second stage which consisted of scaling-up of the new intervention, with implementation conditions very close to the field conditions to take into account the future needs of transferability in practical standard care conditions. The study design used for this phase was the before/ after study (SIMECAM – FGSK project). This type of study was chosen to take into account the organization of the health system with three categories of health facilities at the peripheral level (district hospitals, divisional medical centers and integrated health centers). It also took into account the ethical component resulting from the superiority of the new intervention of COC described in an urban area.

Development of a safe conception training programme for healthcare workers in antiretroviral therapy units in the Volta region, Ghana

Klutsey, Ellen Eyi January 2021 (has links)
Philosophiae Doctor - PhD / Women living with HIV (WLHIV) desire to bear children. Safe conception (SC) education for informed decision-making to prevent peri-conception HIV infection is needed but not routinely available. Poor SC knowledge, attitude, skills in addition to the absence of a standardised training programme were challenges that limited delivery. This study therefore aimed at developing a training programme for healthcare workers to facilitate SC education among WLHIV. The study adopted the intervention research approach. Both qualitative and quantitative methods were employed.

Church-based HIV prevention programs in the African-American church: a scoping analysis

Dowers, Donovan Paul 11 July 2018 (has links)
In lifetime risk for Human Immunodeficiency Virus (HIV), Black men who have sex with men (BMSM) are at the greatest risk of all demographic groups. Creative modes of engagement have been established to reach this group in prevention efforts, including prevention programming in community-based organizations such as churches. Church-based HIV prevention is an emerging area of research and existing studies fall into one of three categories: BMSM’s perspectives on church and church-based HIV prevention, church leaders’ and members’ perspectives on HIV prevention in their congregations, and reported outcomes of HIV prevention interventions that have been conducted in church settings. Given the paucity of research in this area, a scoping analysis was conducted to survey the existing studies in order to identify overarching themes and gaps for future research efforts. In a review of the research, facilitators and barriers to successful implementation of HIV programming in churches emerged. Prominent barriers were stigmatizing sermons given in church and pastoral denial that HIV is a relevant issue to the Black community. Facilitators reported commonly were BMSM’s comfort found in faith and a pastor’s blessing of HIV prevention efforts in churches. Interventions primarily reported lessons learned in implementation of church-based HIV programs. A frequently reported lesson learned was the importance of close collaboration with participant churches to develop program curricula that were effectively couched within church doctrine, and that would be received well by church members. Some interventions also measured intervention efficacy outcomes, one of which showed a statistically significant decrease in HIV stigma post-intervention. This research has important implications for the effective development, implementation, and reporting of outcomes for future, church-based HIV interventions. As research in HIV prevention in the church continues to develop, it may be able to serve as a template for other community-based HIV prevention efforts and open doors for inclusion of other high risk groups such as injection drug users and sex workers.
