RESUMO
In the context of a couples cohort established to evaluate an optimised couples-focused behavioural intervention in rural South Africa, we examined: (1) Is couples' relationship quality (RQ) associated with couples HIV testing and counselling (CHTC) uptake? (2) Does CHTC uptake or the intervention components uptake improve subsequent RQ? Enrolled couples, (n = 218), previously naïve to couples HIV testing, were invited to two group sessions and offered four couples counselling sessions (CS1-CS4), as part of the intervention and administered a questionnaire individually at baseline, four weeks, and four months, which included item-scales to measure RQ: satisfaction, intimacy, dyadic trust, conflict, and mutual constructive communication. Logistic models indicated that no baseline RQ measures were significantly associated with CHTC uptake. Linear regression models showed that CHTC uptake before four weeks assessment significantly improved couples' satisfaction and trust at four weeks, and intimacy at four months. Attending at least one CS was associated with increased satisfaction, intimacy, and decreased conflict within couples at four weeks; the improvement in intimacy was sustained at four months. Consistent with the theoretical interdependence model, our findings suggest that CHTC and CS seemed to strengthen aspects of relationship quality, possibly leading to further collaboration in managing lifestyle changes and treatment adherence.

Background: COVID-19 is likely to have had an impact on the mental wellbeing of prison staff because of the high risk for infectious disease outbreaks in prisons and the pre-existing high burden of mental health issues among staff. Methods: A cross-sectional study of staff within 26 prisons in England was carried out between 20th July 2020 and 2nd October 2020. Mental wellbeing was measured using the Short-version of Warwick-Edinburgh Wellbeing Scale (SWEMWBS). Staff wellbeing was compared to that of the English population using indirectly standardised data from the Health Survey for England 2010-13 and a one-sample t-test. Multivariate linear regression modelling explored associations with mental wellbeing score. Results: Two thousand five hundred and thirty-four individuals were included (response rate 22.2%). The mean age was 44 years, 53% were female, and 93% were white. The sample mean SWEMWBS score was 23.84 and the standardised population mean score was 23.57. The difference in means was statistically significant (95% CI 0.09-0.46), but not of a clinically meaningful level. The multivariate linear regression model was adjusted for age category, sex, ethnicity, smoking status, occupation, and prison service region. Higher wellbeing was significantly associated with older age, male sex, Black/Black British ethnicity, never having smoked, working within the health staff team, and working in certain prison regions. Interpretation: Unexpectedly, prison staff wellbeing as measured by SWEMWBS was similar to that of the general population. Reasons for this are unclear but could include the reduction in violence within prisons since the start of the pandemic. Qualitative research across a diverse sample of prison settings would enrich understanding of staff wellbeing within the pandemic.

BACKGROUND: Between 2012 and 2015, the Uthando Lwethu (UL) study demonstrated that a theory-based behavioural couples-focused intervention significantly increased participation in couples HIV testing and counselling (CHTC) among South African couples who had never previously tested for HIV together or mutually disclosed their HIV status, 42% compared to 12% of the control group at 9 months follow-up. Although effective, we were nonetheless concerned that in this high prevalence setting the majority (58%) of intervention couples chose not to test together. In response we optimised the UL intervention and in a new study, 'Igugu Lethu', we are evaluating the success of the optimised intervention in promoting CHTC. METHODS: One hundred eighty heterosexual couples, who have been in a relationship together for at least 6 months, are being recruited and offered the optimised couples-focused intervention. In the Igugu Lethu study, we have expanded the health screening visit offered to couples to include other health conditions in addition to CHTC. Enrolled couples who choose to schedule CHTC will also have the opportunity to undertake a random blood glucose test, blood pressure and BMI measurements, and self-sample for STI testing as part of their health screening. Individual surveys are administered at baseline, 4 weeks and 4 months follow-up. The proportion of couples who decide to test together for HIV will be compared to the results of the intervention arm in the UL study (historical controls). To facilitate this comparison, we will use the same recruitment and follow-up strategies in the same community as the previous UL study. DISCUSSION: By strengthening communication and functioning within the relationship, the Igugu Lethu study, like the previous UL study, aims to transform the motivation of individual partners from a focus on their own health to shared health as a couple. The Igugu Lethu study findings will answer whether the optimised couples-focused behavioural intervention and offering CHTC as part of a broader health screening for couples can increase uptake of CHTC by 40%, an outcome that would be highly desirable in populations with high HIV prevalence. TRIAL REGISTRATION: Retrospectively registered. ISRCTN Registry ISRCTN 46162564 Registered on 26th May 2022.

OBJECTIVES: This qualitative study explored how to optimise a couples-focused intervention to promote couples HIV testing and counselling (CHTC). SETTING: Community setting in Kwa-Zulu Natal, South Africa. PARTICIPANTS: Qualitative interviews were conducted with 20 couples who had participated in a couples-focused intervention and five staff members delivering the intervention. Partners were interviewed individually by researchers of the same gender. INTERVENTION: A couples-focused intervention comprised of two group sessions and four couples counselling sessions was previously shown to significantly increase uptake to CHTC in Kwa-Zulu Natal, South Africa. However, more than half of couples participating in the intervention still chose not to test together during follow-up. ANALYSIS: The transcripts were analysed using the table of changes from the person-based approach. Proposed optimisations were discussed with a community group to ensure the intervention was as persuasive and acceptable as possible. RESULTS: Many couples found it challenging to discuss CHTC with their partner due to an implied lack of trust. Optimisations to the intervention were identified to increase readiness to discuss CHTC, including education about serodiscordance, discussions about CHTC by peer mentors and open discussion of personal barriers to CHTC during couples' counselling sessions. Additional training for staff in open questioning techniques could help them feel more comfortable to explore couples' perceived barriers to CHTC, rather than advising couples to test. A logic model was developed to show anticipated mechanisms through which the optimised intervention would increase uptake to CHTC, including increasing knowledge, increasing positive outcome beliefs and managing negative emotions. CONCLUSIONS: In-depth qualitative research informed optimisations to a couples-focused intervention for further evaluation in South Africa to encourage uptake to CHTC. Suggestions are made for optimal methods to gain open feedback on intervention experiences where participants may be reluctant to share negative views.

INTRODUCTION: The uptake of HIV testing and linkage to care remains low among men, contributing to high HIV incidence in women in South Africa. We conducted the "Home-Based Intervention to Test and Start" (HITS) in a 2x2 factorial cluster randomized controlled trial in one of the World's largest ongoing HIV cohorts in rural South Africa aimed at enhancing both intrinsic and extrinsic motivations for HIV testing. METHODS: Between February and December 2018, in the uMkhanyakude district of KwaZulu-Natal, we randomly assigned 45 communities (clusters) (n = 13,838 residents) to one of the four arms: (i) financial incentives for home-based HIV testing and linkage to care (R50 [$3] food voucher each); (ii) male-targeted HIV-specific decision support application, called EPIC-HIV; (iii) both financial incentives and male-targeted HIV-specific decision support application and (iv) standard of care (SoC). EPIC-HIV was developed to encourage and serve as an intrinsic motivator for HIV testing and linkage to care, and individually offered to men via a tablet device. Financial incentives were offered to both men and women. Here we report the effect of the interventions on uptake of home-based HIV testing among men. Intention-to-treat (ITT) analysis was performed using modified Poisson regression with adjustment for clustering of standard errors at the cluster levels. RESULTS: Among all 13,838 men ≥ 15 years living in the 45 communities, the overall population coverage during a single round of home-based HIV testing was 20.7%. The uptake of HIV testing was 27.5% (683/2481) in the financial incentives arm, 17.1% (433/2534) in the EPIC-HIV arm, 26.8% (568/2120) in the arm receiving both interventions and 17.8% in the SoC arm. The probability of HIV testing increased substantially by 55% in the financial incentives arm (risk ratio (RR)=1.55, 95% CI: 1.31 to 1.82, p < 0.001) and 51% in the arm receiving both interventions (RR = 1.51, 95% CI: 1.21 to 1.87 p < 0.001), compared to men in the SoC arm. The probability of HIV testing did not significantly differ in the EPIC-HIV arm (RR = 0.96, 95% CI: 0.76 to 1.20, p = 0.70). CONCLUSIONS: The provision of a small financial incentive acted as a powerful extrinsic motivator substantially increasing the uptake of home-based HIV testing among men in rural South Africa. In contrast, the counselling and testing application which was designed to encourage and serve as an intrinsic motivator to test for HIV did not increase the uptake of home-based testing.

Adherence self-efficacy, belief in one's ability to adhere to daily medication, is strongly associated with antiretroviral therapy (ART) adherence and preventing mother-to-child HIV transmission. Couple-based interventions could enhance self-efficacy and adherence. We assessed the relationship between couple HIV testing and counseling (cHTC) and adherence self-efficacy using a 100-point culturally-adapted adherence self-efficacy scale (ASES). Secondarily, we explored the relationship between ASES and ART adherence. Ninety HIV-positive pregnant women at an antenatal clinic in Lilongwe, Malawi were enrolled in an observational cohort study. They were assessed with ASES immediately before and one month after receiving cHTC. Median ASES scores were 100 (IQR 95, 100) before and 100 (IQR 99, 100) after cHTC; there was a significant median difference (p = 0.02) for participants before and after cHTC. This change in ASES scores was associated with the odds of self-reported ART adherence in the full population (OR 1.1, p = 0.01), and there was a trend in the same direction for participants with imperfect baseline ASES scores (OR 1.1, p = 0.2). In our population, adherence self-efficacy and ART adherence were both quite high, and those who had room to improve in self-efficacy may have benefited from cHTC, which in turn could impact ART adherence and ultimately mother-to-child transmission.

INTRODUCTION: The universal test-and-treat (UTT) strategy aims to maximize population viral suppression (PVS), that is, the proportion of all people living with HIV (PLHIV) on antiretroviral treatment (ART) and virally suppressed, with the goal of reducing HIV transmission at the population level. This article explores the extent to which temporal changes in PVS explain the observed lack of association between universal treatment and cumulative HIV incidence seen in the ANRS 12249 TasP trial conducted in rural South Africa. METHODS: The TasP cluster-randomized trial (2012 to 2016) implemented six-monthly repeat home-based HIV counselling and testing (RHBCT) and referral of PLHIV to local HIV clinics in 2 × 11 clusters opened sequentially. ART was initiated according to national guidelines in control clusters and regardless of CD4 count in intervention clusters. We measured residency status, HIV status, and HIV care status for each participant on a daily basis. PVS was computed per cluster among all resident PLHIV (≥16, including those not in care) at cluster opening and daily thereafter. We used a mixed linear model to explore time patterns in PVS, adjusting for sociodemographic changes at the cluster level. RESULTS: 8563 PLHIV were followed. During the course of the trial, PVS increased significantly in both arms (23.5% to 46.2% in intervention, +22.8, p < 0.001; 26.0% to 44.6% in control, +18.6, p < 0.001). That increase was similar in both arms (p = 0.514). In the final adjusted model, PVS increase was most associated with increased RHBCT and the implementation of local trial clinics (measured by time since cluster opening). Contextual changes (measured by calendar time) also contributed slightly. The effect of universal ART (trial arm) was positive but limited. CONCLUSIONS: PVS was improved significantly but similarly in both trial arms, explaining partly the null effect observed in terms of cumulative HIV incidence between arms. The PVS gains due to changes in ART-initiation guidelines alone are relatively small compared to gains obtained by strategies to maximize testing and linkage to care. The achievement of the 90-90-90 targets will not be met if the operational and implementational challenges limiting access to care and treatment, often context-specific, are not properly addressed. Clinical trial number: NCT01509508 (clinicalTrials.gov)/DOH-27-0512-3974 (South African National Clinical Trials Register).

OBJECTIVES: To investigate socioeconomic inequalities, using maternal educational attainment, maternal and partner employment status, and lone motherhood indicators, in the risk of small-for-gestational-age (SGA) births, their time trend, potential mediation by maternal smoking and body mass index, and effect modification by parity. DESIGN: Population-based birth cohort using routine antenatal healthcare data. SETTING: Babies born at University Hospital Southampton, UK, between 2004 and 2016. PARTICIPANTS: 65 909 singleton live births born to mothers aged ≥18 years between 24-week and 42-week gestation. MAIN OUTCOME MEASURES: SGA (birth weight <10th percentile for others born at the same number of completed weeks compared with 2013/2014 within England and Wales). RESULTS: Babies born to mothers educated up to secondary school level (adjusted OR (aOR) 1.32, 99% CI 1.19 to 1.47), who were unemployed (aOR 1.27, 99% CI 1.16 to 1.38) or with unemployed partners (aOR 1.27, 99% CI 1.13 to 1.43), were at greater risk of being SGA. There was no statistically significant change in the magnitude of this risk difference by these indicators over time between 2004 and 2016, as estimated by linear interactions with year of birth. Babies born to lone mothers were not at higher risk compared with partnered mothers after adjusting for maternal smoking (aOR 1.05, 99% CI 0.93 to 1.20). The inverse association between maternal educational attainment and SGA risk appeared greater in multiparous (aOR 1.40, 99% CI 1.10 to 1.77) compared with primiparous women (aOR 1.28, 99% CI 1.12 to 1.47), and the reverse was true for maternal and partner's unemployment where the association was stronger in primiparous women. CONCLUSIONS: Socioeconomic inequalities in SGA risk by educational attainment and employment status are not narrowing over time, with differences in association strength by parity. The greater SGA risk in lone mothers was potentially explained by maternal smoking. Preventive interventions should target socially disadvantaged women, including preconception and postpartum smoking cessation to reduce SGA risk.

BACKGROUND: Although couples HIV testing and counseling (CHTC) is effective for facilitating mutual disclosure and linkage to HIV care, uptake remains low. Using a randomized controlled design, we tested the efficacy of a behavioral couples-based intervention aimed to increase CHTC. SETTING: The Vulindlela district of KwaZulu-Natal, South Africa. METHODS: Couples were recruited from the community (eg, markets and community events). Couples were excluded if mutual HIV serostatus disclosure had occurred. Both partners had to report being each other's primary partner and relationship length was at least 6 months. Assessments occurred at baseline, and 3, 6, and 9 months after intervention. Eligible couples attended a group session (3-4 hours) after which randomization occurred. Intervention couples additionally received: one couples-based group session followed by 4 couples' counseling sessions (1-2 hours). Intervention topics included communication skills, intimate partner violence, and HIV prevention. Our primary outcomes were CHTC and sexual risk behavior. RESULTS: Overall, 334 couples were enrolled. Intervention couples were significantly more likely to have participated in CHTC [42% vs. 12% (P ≤ 0.001)]. In addition, their time to participate in CHTC was significantly shorter (logrank P ≤ 0.0001) (N = 332 couples). By group, 59% of those who tested HIV-positive in intervention and 40% of those who tested in control were new HIV diagnoses (P = 0.18). There were no group differences in unprotected sex. CONCLUSIONS: Our intervention improved CHTC uptake-a vehicle for mutual serostatus disclosure and entrée into HIV treatment, both of which exert a significant public health impact on communities substantially burdened by HIV.

BACKGROUND: Adolescent girls and young women (AGYW) bear the brunt of the HIV epidemic in South Africa. 'DREAMS' aims to reduce HIV incidence through multi-level combination prevention. We describe HIV incidence and uptake of HIV and sexual reproductive health (SRH) by AGYW in KwaZulu-Natal (KZN), prior to DREAMS. METHODS: Longitudinal and cross-sectional analysis of women (15-24 year old) in a population-based HIV incidence cohort within a demographic surveillance site in KZN. Observation time for HIV incidence was person-years at risk while resident. "Current use of contraceptives" and "having an HIV test in the past 12 months" was compared between 2011 and 2015. RESULTS: In 2015, HIV prevalence was 11.0% and 34.1% and HIV incidence (2011-2015) was 4.54% (95%CI:3.89-5.30) and 7.45% (95%CI:6.51-8.51) per year in 15-19 and 20-24 year olds respectively, with no significant decline compared to 2006-2010. In 2015, 90.7% of 20-24-year-olds were unemployed, 36.4% and 51.7% of 15-19 and 20-24 year olds reported recent migration; 20.9% and 72.6% of 15-19 and 20-24 year olds had ever been pregnant. In 2015, less than 50% reported condom-use at last sex, 15.0% of 15-19 year olds and 48.9% of 20-24 year olds were currently using contraception and 32.0% and 66.7% of 15-19 and 20-24 year olds had tested for HIV in the past 12 months. There had been no improvement compared to 2011. Factors associated with AGYW testing for HIV in the past 12 months were, survey year-2011 more likely than 2015 (aOR = 0.50), number of partners (aOR = 3.25), ever been pregnant (aOR = 2.47) and knowing where to find ART (aOR = 1.54). Factors associated with contraception use were being older (aOR = 4.83); ever been pregnant (aOR = 12.62); knowing where to get ART (aOR = 1.79) and having had an HIV test in past 12 months (aOR = 1.74). CONCLUSION: Prior to DREAMS, HIV incidence in AGYW was high. HIV and SRH service uptake did not improve and was suboptimal. Findings highlight the need for combination HIV prevention programmes for AGYW in this economically vulnerable area.

BACKGROUND: Estimates of sexually transmitted infection (STI) prevalence are essential for efforts to prevent and control STIs. Few large STI prevalence studies exist, especially for low- and middle-income countries (LMICs). Our primary objective was to estimate the prevalence of chlamydia, gonorrhea, trichomoniasis, syphilis, herpes simplex virus type 2 (HSV-2), and bacterial vaginosis (BV) among women in sub-Saharan Africa by age, region, and population type. METHODS AND FINDINGS: We analyzed individual-level data from 18 HIV prevention studies (cohort studies and randomized controlled trials; conducted during 1993-2011), representing >37,000 women, that tested participants for ≥1 selected STIs or BV at baseline. We used a 2-stage meta-analysis to combine data. After calculating the proportion of participants with each infection and standard error by study, we used a random-effects model to obtain a summary mean prevalence of each infection and 95% confidence interval (CI) across ages, regions, and population types. Despite substantial study heterogeneity for some STIs/populations, several patterns emerged. Across the three primary region/population groups (South Africa community-based, Southern/Eastern Africa community-based, and Eastern Africa higher-risk), prevalence was higher among 15-24-year-old than 25-49-year-old women for all STIs except HSV-2. In general, higher-risk populations had greater prevalence of gonorrhea and syphilis than clinic/community-based populations. For chlamydia, prevalence among 15-24-year-olds was 10.3% (95% CI: 7.4%, 14.1%; I2 = 75.7%) among women specifically recruited from higher-risk settings for HIV in Eastern Africa and was 15.1% (95% CI: 12.7%, 17.8%; I2 = 82.3%) in South African clinic/community-based populations. Among clinic/community-based populations, prevalence was generally greater in South Africa than in Southern/Eastern Africa for most STIs; for gonorrhea, prevalence among 15-24-year-olds was 4.6% (95% CI: 3.3%, 6.4%; I2 = 82.8%) in South Africa and was 1.7% (95% CI: 1.2%, 2.6%; I2 = 55.2%) in Southern/Eastern Africa. Across the three primary region/population groups, HSV-2 and BV prevalence was high among 25-49-year-olds (ranging from 70% to 83% and 33% to 44%, respectively). The main study limitation is that the data are not from random samples of the target populations. CONCLUSIONS: Combining data from 18 HIV prevention studies, our findings highlight important features of STI/BV epidemiology among sub-Saharan African women. This methodology can be used where routine STI surveillance is limited and offers a new approach to obtaining critical information on STI and BV prevalence in LMICs.

We aimed to understand drivers of HIV-infection in pregnant women in Malawi. The study was conducted in antenatal and labor and delivery wards. HIV-infected women and their partners (cases) were frequency matched in a 1:2 ratio based on age and screening location to HIV-uninfected women and their partners (controls) in a prevalent case-control study. Characteristics associated with female HIV infection were assessed using logistic regression modeling. At screening, HIV-infected women were more likely to have partners outside Lilongwe than HIV-uninfected women (24% vs. 0%, p < 0.0001). Case females were more likely to have HIV-infected study partners than control females (75% vs. 4%, p < 0.0001). The odds of female HIV-infection were higher if either couple member reported ≥ 2 lifetime marriages (OR 9.0, CI 2.6-30.9) or ≥ 3 lifetime partners (OR 18.0, CI 3.1-103.6) and lower if either reported past couple HIV testing and counseling (OR 0.1, CI 0.04-0.3). Targeting women with migrating partners, promoting couple HIV testing and counseling, and limiting partners could slow HIV transmission.

BACKGROUND: Universal antiretroviral therapy (ART), as per the 2015 WHO recommendations, might reduce population HIV incidence. We investigated the effect of universal test and treat on HIV acquisition at population level in a high prevalence rural region of South Africa. METHODS: We did a phase 4, open-label, cluster randomised trial of 22 communities in rural KwaZulu-Natal, South Africa. We included individuals residing in the communities who were aged 16 years or older. The clusters were composed of aggregated local areas (neighbourhoods) that had been identified in a previous study in the Hlabisa subdistrict. The study statisticians randomly assigned clusters (1:1) with MapInfo Pro (version 11.0) to either the control or intervention communities, stratified on the basis of antenatal HIV prevalence. We offered residents repeated rapid HIV testing during home-based visits every 6 months for about 4 years in four clusters, 3 years in six clusters, and 2 years in 12 clusters (58 cluster-years) and referred HIV-positive participants to trial clinics for ART (fixed-dose combination of tenofovir, emtricitabine, and efavirenz) regardless of CD4 cell count (intervention) or according to national guidelines (initially ≤350 cells per µL and <500 cells per µL from January, 2015; control). Participants and investigators were not masked to treatment allocation. We used dried blood spots once every 6 months provided by participants who were HIV negative at baseline to estimate the primary outcome of HIV incidence with cluster-adjusted Poisson generalised estimated equations in the intention-to-treat population after 58 cluster-years of follow-up. This study is registered with ClinicalTrials.gov, number NCT01509508, and the South African National Clinical Trials Register, number DOH-27-0512-3974. FINDINGS: Between March 9, 2012, and June 30, 2016, we contacted 26â518 (93%) of 28â419 eligible individuals. Of 17â808 (67%) individuals with a first negative dried blood spot test, 14â223 (80%) had subsequent dried blood spot tests, of whom 503 seroconverted after follow-up of 22â891 person-years. Estimated HIV incidence was 2·11 per 100 person-years (95% CI 1·84-2·39) in the intervention group and 2·27 per 100 person-years (2·00-2·54) in the control group (adjusted hazard ratio 1·01, 95% CI 0·87-1·17; p=0·89). We documented one case of suicidal attempt in a woman following HIV seroconversion. 128 patients on ART had 189 life-threatening or grade 4 clinical events: 69 (4%) of 1652 in the control group and 59 (4%) of 1367 in the intervention group (p=0·83). INTERPRETATION: The absence of a lowering of HIV incidence in universal test and treat clusters most likely resulted from poor linkage to care. Policy change to HIV universal test and treat without innovation to improve health access is unlikely to reduce HIV incidence. FUNDING: ANRS, GiZ, and 3ie.

BACKGROUND: In sub-Saharan Africa couple HIV testing and counseling (CHTC) has been associated with substantial increases in safe sex, especially when at least one partner is HIV infected. However, this relationship has not been characterized in an Option B+ context. SETTING: The study was conducted at the antenatal clinic at Bwaila District Hospital in Lilongwe, Malawi in 2016 under an Option B+ program. METHODS: Ninety heterosexual couples with an HIV-infected pregnant woman (female-positive couples) and 47 couples with an HIV-uninfected pregnant woman (female-negative couples) were enrolled in an observational study. Each couple member was assessed immediately before and 1 month after CHTC for safe sex (abstinence or consistent condom use in the last month). Generalized estimating equations were used to model change in safe sex before and after CHTC and to compare safe sex between female-positive and female-negative couples. RESULTS: Mean age was 26 years among women and 32 years among men. Before CHTC, safe sex was comparable among female-positive couples (8%) and female-negative couples (2%) [risk ratio (RR): 3.7, 95% confidence interval (CI): 0.5 to 29.8]. One month after CHTC, safe sex was higher among female-positive couples (75%) than among female-negative couples (3%) (RR: 30.0, 95% CI: 4.3 to 207.7). Safe sex increased substantially after CTHC for female-positive couples (RR 9.6, 95% CI: 4.6 to 20.0), but not for female-negative couples (RR: 1.2, 95% CI: 0.1 to 18.7). CONCLUSIONS: Engaging pregnant couples in CHTC can have prevention benefits for couples with an HIV-infected pregnant woman, but additional prevention approaches may be needed for couples with an HIV-uninfected pregnant woman.

OBJECTIVES: Partners are a significant influence on individuals' health, and concordance in health behaviours increases over time in couples. Several theories suggest that couple-focused interventions for health behaviour change may therefore be more effective than individual interventions. DESIGN: A systematic review of health behaviour change interventions for couples was conducted. METHODS: Systematic search methods identified randomized controlled trials (RCTs) and non-randomized interventions of health behaviour change for couples with at least one member at risk of a chronic physical illness, published from 1990-2014. RESULTS: We identified 14 studies, targeting the following health behaviours: cancer prevention (6), obesity (1), diet (2), smoking in pregnancy (2), physical activity (1) and multiple health behaviours (2). In four out of seven trials couple-focused interventions were more effective than usual care. Of four RCTs comparing a couple-focused intervention to an individual intervention, two found that the couple-focused intervention was more effective. CONCLUSIONS: The studies were heterogeneous, and included participants at risk of a variety of illnesses. In many cases the intervention was compared to usual care for an individual or an individual-focused intervention, which meant the impact of the couplebased content could not be isolated. Three arm studies could determine whether any added benefits of couple-focused interventions are due to adding the partner or specific content of couple-focused interventions. Statement of contribution What is already known on this subject? Health behaviours and health behaviour change are more often concordant across couples than between individuals in the general population. Couple-focused interventions for chronic conditions are more effective than individual interventions or usual care (Martire, Schulz, Helgeson, Small, & Saghafi, ). What does this study add? Identified studies targeted a variety of health behaviours, with few studies in any one area. Further assessment of the effectiveness of couple-focused versus individual interventions for those at risk is needed. Three-arm study designs are needed to determine benefits of targeting couples versus couple-focused intervention content.

Men's poorer engagement with healthcare generally and HIV care specifically, compared to women, is well-described. Within the HIV public health domain, interest is growing in universal test and treat (UTT) strategies. UTT strategies refer to the expansion of antiretroviral therapy (ART) in order to reduce onward transmission and incidence of HIV in a population, through a "treatment as prevention" (TasP). This paper focuses on how masculinity influences engagement with HIV care in the context of an on-going TasP trial. Data were collected in January-November 2013 using 20 in-depth interviews, 10 of them repeated thrice, and 4 focus group discussions, each repeated four times. Analysis combined inductive and deductive approaches for coding and the review and consolidation of emerging themes. The accounts detailed men's unwillingness to engage with HIV testing and care, seemingly tied to their pursuit of valued masculinity constructs such as having strength and control, being sexually competent, and earning income. Articulated through fears regarding getting an HIV-positive diagnosis, observations that men preferred traditional medicine and that primary health centres were not welcoming to men, descriptions that men used lay measures to ascertain HIV status, and insinuations by men that they were removed from HIV risk, the indisposition to HIV care contrasted markedly with an apparent readiness to test among women. Gendered tensions thus emerged which were amplified in the context where valued masculinity representations were constantly threatened. Amid the tensions, men struggled with disclosing their HIV status, and used various strategies to avoid or postpone disclosing, or disclose indirectly, while women's ability to access care readily, use condoms, or communicate about HIV appeared similarly curtailed. UTT and TasP promotion should heed and incorporate into policy and health service delivery models the intrapersonal tensions, and the conflict, and poor and indirect communication at the micro-relational levels of couples and families.

In the context of the ANRS 12249 Treatment as Prevention (TasP) trial, we investigated perceptions of regular and repeat HIV-testing in rural KwaZulu-Natal (South Africa), an area of very high HIV prevalence and incidence. We conducted two qualitative studies, before (2010) and during the early implementation stages of the trial (2013-2014), to appreciate the evolution in community perceptions of repeat HIV-testing over this period of rapid changes in HIV-testing and treatment approaches. Repeated focus group discussions were organized with young adults, older adults and mixed groups. Repeat and regular HIV-testing was overall well perceived before, and well received during, trial implementation. Yet community members were not able to articulate reasons why people might want to test regularly or repeatedly, apart from individual sexual risk-taking. Repeat home-based HIV-testing was considered as feasible and convenient, and described as more acceptable than clinic-based HIV-testing, mostly because of privacy and confidentiality. However, socially regulated discourses around appropriate sexual behaviour and perceptions of stigma and prejudice regarding HIV and sexual risk-taking were consistently reported. This study suggests several avenues to improve HIV-testing acceptability, including implementing diverse and personalised approaches to HIV-testing and care, and providing opportunities for antiretroviral therapy initiation and care at home.

The ANRS 12249 Treatment-as-Prevention (TasP) cluster-randomized trial in rural South Africa uses a "test and treat" approach. Home-based testing services and antiretroviral treatment initiation satellite clinics were implemented in every cluster as part of the trial. A social science research agenda was nested within TasP with the aim of understanding the social, economic and contextual factors that affect individuals, households, communities and health systems with respect to TasP. Considering the rural nature of the trial setting, we sought to understand community perceptions and experiences of the TasP Trial interventions as seen through the eyes of traditional health practitioners (THPs). A qualitative study design was adopted using four repeat focus group discussions conducted with nine THPs, combined with community walks and photo-voice techniques, over a period of 18 months. A descriptive, interpretive and explanatory approach to analysis was adopted. Findings indicate that THPs engaged with the home-based testing services and HIV clinics established for TasP. Specifically, home-based testing services were perceived as relatively successful in increasing access to HIV testing. A major gap observed by THPs was linkage to HIV clinics. Most of their clients, and some of the THPs themselves, found it difficult to use HIV clinics due to fear of labelling, stigma and discrimination, and the ensuing personal implications of unsolicited disclosure. On the one hand, a growing number of patients diagnosed with HIV have found sanctuary with THPs as alternatives to clinics. On the other hand, THPs in turn have been struggling to channel patients suspected of HIV into clinics through referrals. Therefore, acceptability of the TasP test and treat approach by THPs is a major boost to the intervention, but further success can be achieved through strengthened ties with communities to combat stigma and effectively link patients into HIV care, including partnerships with THPs themselves.

Critical to preventing the spread of HIV is promoting condom use among HIV-positive individuals. Previous studies suggest that gender norms (social and cultural constructions of the ways that women and men are expected to behave) may be an important determinant of condom use. However, the relationship has not been evaluated among HIV-positive women and men in South Africa. We examined gender norms and condom use at last sex among 550 partnerships reported by 530 sexually-active HIV-positive women (372) and men (158) who had sought care, but not yet initiated antiretroviral therapy in a high HIV-prevalence rural setting in KwaZulu-Natal, South Africa between January 2009 and March 2011. Participants enrolled in the cohort study completed a baseline questionnaire that detailed their socio-demographic characteristics, socio-economic circumstances, religion, HIV testing history and disclosure of HIV status, stigma, social capital, gender norms and self-efficacy. Gender norms did not statistically differ between women and men (p = 0.18). Overall, condoms were used at last sex in 58% of partnerships. Although participants disclosed their HIV status in 66% of the partnerships, 60% did not have knowledge of their partner's HIV status. In multivariable logistic regression, run separately for each sex, women younger than 26 years with more equitable gender norms were significantly more likely to have used a condom at last sex than those of the same age group with inequitable gender norms (OR = 8.88, 95% CI 2.95-26.75); the association between condom use and gender norms among women aged 26+ years and men of all ages was not statistically significant. Strategies to address gender inequity should be integrated into positive prevention interventions, particularly for younger women, and supported by efforts at a societal level to decrease gender inequality.

BACKGROUND: The Universal HIV Test and Treat (UTT) strategy represents a challenge for science, but is also a challenge for individuals and societies. Are repeated offers of provider-initiated HIV testing and immediate antiretroviral therapy (ART) socially-acceptable and can these become normalized over time? Can UTT be implemented without potentially adding to individual and community stigma, or threatening individual rights? What are the social, cultural and economic implications of UTT for households and communities? And can UTT be implemented within capacity constraints and other threats to the overall provision of HIV services? The answers to these research questions will be critical for routine implementation of UTT strategies. METHODS/DESIGN: A social science research programme is nested within the ANRS 12249 Treatment-as-Prevention (TasP) cluster-randomised trial in rural South Africa. The programme aims to inform understanding of the (i) social, economic and environmental factors affecting uptake of services at each step of the continuum of HIV prevention, treatment and care and (ii) the causal impacts of the TasP intervention package on social and economic factors at the individual, household, community and health system level. We describe a multidisciplinary, multi-level, mixed-method research protocol that includes individual, household, community and clinic surveys, and combines quantitative and qualitative methods. DISCUSSION: The UTT strategy is changing the overall approach to HIV prevention, treatment and care, and substantial social consequences may be anticipated, such as changes in social representations of HIV transmission, prevention, HIV testing and ART use, as well as changes in individual perceptions and behaviours in terms of uptake and frequency of HIV testing and ART initiation at high CD4. Triangulation of social science studies within the ANRS 12249 TasP trial will provide comprehensive insights into the acceptability and feasibility of the TasP intervention package at individual, community, patient and health system level, to complement the trial's clinical and epidemiological outcomes. It will also increase understanding of the causal impacts of UTT on social and economic outcomes, which will be critical for the long-term sustainability and routine UTT implementation.
