High levels of postmigration HIV acquisition within nine European countries
OBJECTIVE: We aimed to estimate the proportion of post-migration HIV acquisition among HIV-positive migrants in Europe. DESIGN: To reach HIV positive migrants we designed a cross sectional study performed in HIV clinics. METHODS: The study was conducted from July 2013-July 2015 in 57 clinics (9 European countries, targeting individuals over 18 years diagnosed in the preceding 5 years and born abroad. Electronic questionnaires supplemented with clinical data were completed in any of 15 languages. Post-migration HIV acquisition was estimated through Bayesian approaches combining extensive information on migration and patients' characteristics. CD4 counts and HIV-RNA trajectories from seroconversion were estimated by bivariate linear mixed models fitted to natural history data. Post-migration acquisition risk factors were investigated with weighted logistic regression. RESULTS: Of 2009 participants, 46% were men who have sex with men (MSM) and a third originated from Sub-Saharan Africa (SSA) and Latin America & Caribbean (LAC), respectively. Median time in host countries was 8 years. Post-migration HIV acquisition was 63% (95% CI: 57%-67%); 72% among MSM, 58% and 51% in heterosexual men and women, respectively. Post-migration HIV acquisition was 71% for LAC migrants and 45% for people from SSA. Factors associated with post-migration HIV acquisition among heterosexual women and MSM were age at migration, length of stay in host country and HIV diagnosis year and among heterosexual men, length of stay in host country, and HIV diagnosis year. CONCLUSIONS: A substantial proportion of HIV-positive migrants living in Europe acquired HIV post-migration. This has important implications for European public health policies

Publisher Copyright: © 2018 The Authors.To close gaps in HIV prevention and care, knowledge about locations and populations most affected by HIV is essential. Here, we provide subnational and sub-population estimates of three key HIV epidemiological indicators, which have been unavailable for most settings. Methods: We used surveillance data on newly diagnosed HIV cases from 2004 to 2014 and back-calculation modelling to estimate in France, at national and subnational levels, by exposure group and country of birth: the numbers of new HIV infections, the times to diagnosis, the numbers of undiagnosed HIV infections. The denominators used for rate calculations at national and subnational levels were based on population size (aged 18 to 64) estimates produced by the French National Institute of Statistics and Economic Studies and the latest national surveys on sexual behaviour and drug use. Results: We estimated that, in 2014, national HIV incidence was 0.17& (95% confidence intervals (CI): 0.16 to 0.18) or 6607 (95% CI: 6057 to 7196) adults, undiagnosed HIV prevalence was 0.64& (95% CI: 0.57 to 0.70) or 24,197 (95% CI: 22,296 to 25,944) adults and median time to diagnosis over the 2011 to 2014 period was 3.3 years (interquartile range: 1.2 to 5.7). Three mainland regions, including the Paris region, out of the 27 French regions accounted for 56% of the total number of new and undiagnosed infections. Incidence and undiagnosed prevalence rates were 2-to 10-fold higher than the national rates in three overseas regions and in the Paris region (p-values < 0.001). Rates of incidence and undiagnosed prevalence were higher than the national rates for the following populations (p-values < 0.001): born-abroad men who have sex with men (MSM) (respectively, 108-and 78-fold), French-born MSM (62-and 44-fold), born-abroad persons who inject drugs (14-and 18-fold), sub-Saharan African-born heterosexuals (women 15-and 15-fold, men 11-and 13-fold). Importantly, affected populations varied from one region to another, and in regions apparently less impacted by HIV, some populations could be as impacted as those living in most impacted regions. Conclusions: In France, some regions and populations have been most impacted by HIV. Subnational and sub-population estimates of key indicators are not only essential to adapt, design implement and evaluate tailored HIV interventions in France, but also elsewhere where similar heterogeneity is likely to exist.publishersversionPeer reviewe
"I will not let my HIV status stand in the way." Decisions on motherhood among women on ART in a slum in Kenya- a qualitative study
"Men are always scared to test with their partners … it is like taking them to the Police": Motivations for and barriers to couples' HIV counselling and testing in Rakai, Uganda: a qualitative study.
INTRODUCTION: Uptake of couples' HIV counselling and testing (couples' HCT) can positively influence sexual risk behaviours and improve linkage to HIV care among HIV-positive couples. However, less than 30% of married couples have ever tested for HIV together with their partners. We explored the motivations for and barriers to couples' HCT among married couples in Rakai, Uganda. METHODS: This was a qualitative study conducted among married individuals and selected key informants between August and October 2013. Married individuals were categorized by prior HCT status as: 1) both partners never tested; 2) only one or both partners ever tested separately; and 3) both partners ever tested together. Data were collected on the motivations for and barriers to couples' HCT, decision-making processes from tested couples and suggestions for improving couples' HCT uptake. Eighteen focus group discussions with married individuals, nine key informant interviews with selected key informants and six in-depth interviews with married individuals that had ever tested together were conducted. All interviews were audio-recorded, translated and transcribed verbatim and analyzed using Nvivo (version 9), following a thematic framework approach. RESULTS: Motivations for couples' HCT included the need to know each other's HIV status, to get a treatment companion or seek HIV treatment together - if one or both partners were HIV-positive - and to reduce mistrust between partners. Barriers to couples' HCT included fears of the negative consequences associated with couples' HCT (e.g. fear of marital dissolution), mistrust between partners and conflicting work schedules. Couples' HCT was negotiated through a process that started off with one of the partners testing alone initially and then convincing the other partner to test together. Suggestions for improving couples' HCT uptake included the need for couple- and male-partner-specific sensitization, and the use of testimonies from tested couples. CONCLUSIONS: Couples' HCT is largely driven by individual and relationship-based factors while fear of the negative consequences associated with couples' HCT appears to be the main barrier to couples' HCT uptake in this setting. Interventions to increase the uptake of couples' HCT should build on the motivations for couples' HCT while dealing with the negative consequences associated with couples' HCT
How Treatment Partners Help: Social Analysis of an African Adherence Support Intervention
Treatment partnering is an adherence intervention developed in sub-Saharan Africa. This paper describes the additional social functions that treatment partners serve and shows how these functions contribute to health and survival for patients with HIV/AIDS. Ninety-eight minimally structured interviews were conducted with twenty pairs of adult HIV/AIDS patients (N = 20) and treatment partners (N = 20) treated at a public HIV-care setting in Tanzania. Four social functions were identified using inductive, category construction and interpretive methods of analysis: (1) encouraging disclosure; (2) combating stigma; (3) restoring hope; and (4) reducing social difference. These functions work to restore social connections and reverse the isolating effects of HIV/AIDS, strengthening access to essential community safety nets. Besides encouraging ARV adherence, treatment partners contribute to the social health of patients. Social health as well as HIV treatment success is essential to survival for persons living with HIV/AIDS in sub-Saharan Africa
Bidirectional links between HIV and intimate partner violence in pregnancy: implications for prevention of mother-to-child transmission.
INTRODUCTION: Prevention of mother-to-child transmission (PMTCT) has the potential to eliminate new HIV infections among infants. Yet in many parts of sub-Saharan Africa, PMTCT coverage remains low, leading to unacceptably high rates of morbidity among mothers and new infections among infants. Intimate partner violence (IPV) may be a structural driver of poor PMTCT uptake, but has received little attention in the literature to date. METHODS: We conducted qualitative research in three Johannesburg antenatal clinics to understand the links between IPV and HIV-related health of pregnant women. We held focus group discussions with pregnant women (n=13) alongside qualitative interviews with health care providers (n=10), district health managers (n=10) and pregnant abused women (n=5). Data were analysed in Nvivo10 using a team-based approach to thematic coding. FINDINGS: We found qualitative evidence of strong bidirectional links between IPV and HIV among pregnant women. HIV diagnosis during pregnancy, and subsequent partner disclosure, were noted as a common trigger of IPV. Disclosure leads to violence because it causes relationship conflict, usually related to perceived infidelity and the notion that women are "bringing" the disease into the relationship. IPV worsened HIV-related health through poor PMTCT adherence, since taking medication or accessing health services might unintentionally alert male partners of the women's HIV status. IPV also impacted on HIV-related health via mental health, as women described feeling depressed and anxious due to the violence. IPV led to secondary HIV risk as women experienced forced sex, often with little power to negotiate condom use. Pregnant women described staying silent about condom negotiation in order to stay physically safe during pregnancy. CONCLUSIONS: IPV is a crucial issue in the lives of pregnant women and has bidirectional links with HIV-related health. IPV may worsen access to PMTCT and secondary prevention behaviours, thereby posing a risk of secondary transmission. IPV should be urgently addressed in antenatal care settings to improve uptake of PMTCT and ensure that goals of maternal and child health are met in sub-Saharan African settings
Contraceptive Use and Method Preference among Women in Soweto, South Africa: The Influence of Expanding Access to HIV Care and Treatment Services
Objective: Preventing unintended pregnancy among HIV-positive women constitutes a critical and cost-effective approach to primary prevention of mother-to-child transmission of HIV and is a global public health priority for addressing the desperate state of maternal and child health in HIV hyper-endemic settings. We sought to investigate whether the prevalence of contraceptive use and method preferences varied by HIV status and receipt of highly active antiretroviral therapy (HAART) among women in Soweto, South Africa. Methods: We used survey data from 563 sexually active, non-pregnant women (18–44 years) recruited from the Perinatal HIV Research Unit in Soweto (May–December, 2007); 171 women were HIV-positive and receiving HAART (median duration of use = 31 months; IQR = 28, 33), 178 were HIV-positive and HAART-naïve, and 214 were HIV-negative. Medical record review was conducted to confirm HIV status and clinical variables. Logistic regression models estimated adjusted associations between HIV status, receipt of HAART, and contraceptive use. Results: Overall, 78 % of women reported using contraception, with significant variation by HIV status: 86 % of HAART users, 82 % of HAART-naïve women, and 69 % of HIV-negative women (p,0.0001). In adjusted models, compared with HIVnegativ
Framing rights and responsibilities: accounts of women with a history of AIDS activism
<p>Abstract</p> <p>Background</p> <p>In South Africa, policy with respect to HIV/AIDS has had a strong rights-based framing in line with international trends and in keeping with the constitutional overhaul in the post-Apartheid era. There have also been considerable advances since 1994 towards legal enshrinement of sexual and reproductive health rights and in the provision of related services. Since HIV in this setting has heavily affected women of reproductive age, there has been discussion about the particular needs of this subgroup, especially in the context of service integration. This paper is concerned with the way in which HIV positive women conceptualise these rights and whether they wish and are able to actualise them in their daily lives.</p> <p>Methods</p> <p>In 2003 a group of women involved with the Treatment Action Campaign and Medicines Sans Frontières participated in an initiative to ‘map’ their bodies as affected by the virus. A book containing the maps and narratives was published and used as a political tool to pressure the government of the day to roll out antiretroviral therapy (ART) to the population. In 2008, the authors coordinated an initiative that involved conducting follow-up in-depth interviews in which five of these women reflected on those body maps and on how their lives had changed in the intervening five years since gaining the right to treatment through the public sector.</p> <p>Results</p> <p>Drawing upon this qualitative data and published sources, these new accounts are analysed in order to reflect the perspectives of these women living with chronic HIV with respect to their sexual relations and fertility desires. The paper reveals difficulties faced by these women in negotiating sexual relationships and disclosure of their HIV positive status. It focuses on how they perceive relative responsibilities in terms of taking preventative measures in sexual encounters. Women adopt tactics within a context characterised by various inequalities in order to ‘make do’, such as by remaining silent about their status. Concerns about childbearing can be addressed by information and support from a health care worker.</p> <p>Conclusions</p> <p>Women’s experience of HIV as a chronic illness and the need to adhere to ART, is linked to the way in which the language of responsibility can come to counter-balance a language of rights in treatment programmes.</p
