Assessment of a couples HIV counseling and testing program for pregnant women and their partners in antenatal care (ANC) in 7 provinces, Thailand

Efficacy of mobile phone intervention to increase male partner antenatal care attendance for HIV testing in Moshi municipal, Tanzania: a randomized controlled trial

BACKGROUND

HIV partner counselling and testing in antenatal care (ANC) is a crucial strategy to raise the number of males who know their HIV status. However, in many settings like Tanzania, male involvement in antenatal care remains low, and there is a definite need for innovative strategies to increase male partner involvement. This study was designed to evaluate the efficacy of mobile phone intervention increase male partner ANC attendance for HIV testing in Moshi municipal, Tanzania.

METHODS

Between April and July 2022, we enrolled pregnant women presenting to a first ANC visit at Majengo and St. Joseph reproductive health facilities without their male partners. Eligible pregnant women were randomly assigned to invitation of their male partners either via phone calls, text messages from clinic staff and verbal invites from pregnant partners (intervention arm) or verbal invites only from the pregnant partners (control arm). Neither healthcare provider nor participant were blinded. The primary outcome was the proportion of male partners who attended ANC with their pregnant partners during a follow-up period of two consecutive visits. The secondary outcome measure was HIV testing among male partners following the invitation. Participants were analyzed as originally assigned (intention to treat).

RESULTS

A total of 350 pregnant women presenting to ANC for the first time were enrolled, with 175 women enrolled in each arm. The efficacy of male attendance with their pregnant women following the invitations was 83.4% (147/175) in the intervention arm and 46.3% (81/175) in the control arm. Overall, the results suggest a positive and statistically significant average treatment effect among men who received mobile phone intervention on ANC attendance. For the secondary outcome, the percent of male partners who accepted HIV counselling and testing was 99.3% (146/147) in the intervention arm and 93.8% (76/81) in the control arm. Married men were having higher odds of ANC attendance compared with single men (aOR:6.40(3.26-12.56), Males with multigravida women were having lower odds of ANC attendance compared with primigravida women (aOR:0.17(0.09-0.33).

CONCLUSION

The study demonstrates that supplementing verbal invitations with mobile phone calls and text messages from clinic staff can significantly increase male partner ANC attendance and HIV testing. This combined approach is recommended in improving ANC attendance and HIV testing of male partners who do not accompany their pregnant partners to antenatal clinics in the first visits.

Access to HIV/STI testing among male and female Venezuelan migrants in Peru: evidence from a nationwide survey

BACKGROUND

Human immunodeficiency virus (HIV) infection and sexually transmitted infections (STIs) are major global public health issues. Migrants represent a vulnerable group that faces multiple barriers to access to healthcare services, including HIV/STI testing. This study aimed to assess the factors associated with access to HIV/STI testing in male and female Venezuelan migrants in Peru.

METHODS

This was a cross-sectional study involving secondary data analysis of the 2022 Venezuelan Population Residing in Peru Survey. The study was conducted in the eight most populated cities inhabited by Venezuelan migrants and refugees. For each city, the sampling design was probabilistic, stratified, and independent. The outcome variable was whether participants had access to HIV or other STI testing during their stay in Peru. Statistical analysis was stratified by sex owing to potential effect modification. Crude and adjusted prevalence ratios were calculated using generalized linear models Poisson family with log link function. Confidence intervals were calculated to 95%.

RESULTS

A total of 3,723 male and 3,984 female migrants were included. Access to HIV/STI testing among male and female migrants was 19.85% and 25.16%, respectively. Among male migrants, being LGBTI, health insured, and married or cohabiting were associated with increased access to HIV/STI testing. Among females, those aged 18-44 years, those who were married or cohabiting and were health insured, and those residing for more than 1 year in Peru were significantly more likely to have access to HIV/STI testing. Moreover, physical/mental disability and unemployed status were associated with a lower probability of HIV/STI testing in females.

CONCLUSIONS

Only two in ten Venezuelan migrants and refugees in Peru were screened for HIV/STI, with fewer males than females. Sex-specific sociodemographic, health-related, and migration-related variables were independently associated with access to HIV/STI testing.

Socio-cultural and economic barriers, and facilitators influencing men's involvement in antenatal care including HIV testing: a qualitative study from urban Blantyre, Malawi

Background

Male partner involvement in antenatal care (ANC) is associated with positive maternal and neonatal outcomes. However, only a handful of men attend ANC with their partners. This study aimed to understand the underlying barriers and facilitators influencing men’s ANC attendance including HIV testing in Blantyre, Malawi.

Methods

Data were collected during a formative qualitative study of a cluster-randomised trial. Six focus group discussions (FGDs) with 42 men and women and 20 in-depth interviews (IDIs) were conducted at three primary health centres in urban Blantyre, Malawi. FGD participants were purposively sampled with IDI participants subsequently sampled after FGD participation. Thematic analysis was used to analyse the data.

Results

The economic requirement to provide for their families exerted pressure on men and often negatively affected their decision to attend ANC together with their pregnant partners despite obvious benefits. Peer pressure and the fear to be seen by peers queueing for services at ANC, an environment traditionally viewed as a space for women and children made men feel treated as trespassers and with some level of hostility rendering them feeling emasculated when they attend ANC. Health system problems associated with overall organization of the ANC services, which favours women created resistance among men to be involved. An association between ANC and HIV testing services discouraged men from attending ANC because of their fear of testing HIV-positive in the presence of their partners. The availability of a male friendly clinic offering a private, quick, supportive/sensitive and flexible service was considered to be an important incentive that would facilitate men’s ANC attendance. Men described compensation to cover transport and opportunity cost for attending the clinic as a motivator to attending ANC services and accepting an HIV test.

Conclusion

Peer and economic influences were the most influential barriers of men attending ANC and testing for HIV with their pregnant partners. Addressing these socio-economic barriers and having a male friendly clinic are promising interventions to promote male ANC attendance in this setting.

Cost-effectiveness of couples' voluntary HIV counselling and testing in six African countries: a modelling study guided by an HIV prevention cascade framework

INTRODUCTION

Couples' voluntary HIV counselling and testing (CVCT) is a high-impact HIV prevention intervention in Rwanda and Zambia. Our objective was to model the cost-per-HIV infection averted by CVCT in six African countries guided by an HIV prevention cascade framework. The HIV prevention cascade as yet to be applied to evaluating CVCT effectiveness or cost-effectiveness.

METHODS

We defined a priority population for CVCT in Africa as heterosexual adults in stable couples. Based on our previous experience nationalizing CVCT in Rwanda and scaling-up CVCT in 73 clinics in Zambia, we estimated HIV prevention cascade domains of motivation for use, access and effectiveness of CVCT as model parameters. Costs-per-couple tested were also estimated based on our previous studies. We used these parameters as well as country-specific inputs to model the impact of CVCT over a five-year time horizon in a previously developed and tested deterministic compartmental model. We consider six countries across Africa with varied HIV epidemics (South Africa, Zimbabwe, Kenya, Tanzania, Ivory Coast and Sierra Leone). Outcomes of interest were the proportion of HIV infections averted by CVCT, nationwide CVCT implementation costs and costs-per-HIV infection averted by CVCT. We applied 3%/year discounting to costs and outcomes. Univariate and Monte Carlo multivariate sensitivity analyses were conducted.

RESULTS

We estimated that CVCT could avert between 54% (Sierra Leone) and 62% (South Africa) of adult HIV infections. Average costs-per-HIV infection averted were lowest in Zimbabwe ($550) and highest in South Africa ($1272). Nationwide implementations would cost between 7% (Kenya) and 21% (Ivory Coast) of a country's President's Emergency Plan for AIDS Relief (PEPFAR) budget over five years. In sensitivity analyses, model outputs were most sensitive to estimates of cost-per-couple tested; the proportion of adults in heterosexual couples and HIV prevention cascade domains of CVCT motivation and access.

CONCLUSIONS

Our model indicates that nationalized CVCT could prevent over half of adult HIV infections for 7% to 21% of the modelled countries' five-year PEPFAR budgets. While other studies have indicated that CVCT motivation is high given locally relevant promotional and educational efforts, without required indicators, targets and dedicated budgets, access remains low.

Husband's willingness-to-pay for HIV and syphilis screening at antenatal care clinic under the Thai universal coverage scheme

Background

Screening for sexually transmitted infection (STI) especially HIV as early detection and treatment have been financially supported under the Thai Universal Coverage (UC) scheme since 2009 (THB140 for HIV). However, the implementation has not been evidence-based, strategic risk-based, nor economically evaluated whereas husbands who accompanied the pregnant women are likely to have a lower risk than those who did not come along. This study is aimed to determine the husband’s willingness-to-pay (WTP) for his HIV and syphilis screening tests and potential factors affecting STI screenings at the antenatal care (ANC) clinic of a tertiary hospital in Thailand.

Methods

A pilot open-ended interview was conducted among 50 participants to estimate the mean and standard deviation of WTP prices for HIV and syphilis screening tests. A questionnaire was developed to obtain demographics, STI knowledge and screening history, as well as two contingent valuation methods (bidding and payment scale), using the mean WTP prices identified from the pilot study as a starting WTP with ¼SD step-up/down. The survey of 200 randomly selected husbands of pregnant women was conducted at King Chulalongkorn Memorial Hospital from April to June 2018. Descriptive statistics and logistic regression were used for data analysis.

Results

During the study period, 597 pregnant women received their first ANC. Of 368 accompanying husbands, 200 were enrolled in the study. Their median age was 31 (IQR 27–36) years old and 67% had a first child. Eighty-eight percent of the participants were willing to test for the STIs. Based on the bidding method, WTP prices for HIV and syphilis screening tests were US$14.5 (IQR 12.4–14.5) and US$9.7 (IQR 10–12), respectively. The payment scale method suggested approximately three-quarters of the WTP prices from the bidding method.

Conclusions

The husbands who accompanied their pregnant wives to the ANC clinic showed positive behaviors according to the propitious selection theory. They tend to cooperate well with STI testing and are willing to pay at least two times the price of the STI screening tests. The financial support to promote STI screenings should be reconsidered to cover other groups with higher sexual behavior risks and less WTP.

Male involvement in prevention of mother to child transmission of human immuno virus and associated factors among partners' of reproductive age women at Debre Tabor town, Northwest Ethiopia: a community based cross sectional study

Objective

The aim of this study was to determine the prevalence of male involvement in prevention of mother to child transmission (PMTCT) of human immune virus (HIV) and associated factors among partners’ of reproductive age women at Debre Tabor town, Northwest Ethiopia. A community based cross sectional study was employed among 561 study participants. Data was collected with pretested structured questionnaire. The data was entered by Epi-Info version 7 software and exported to SPSS version 23 for analysis. Statistical significance was declared at P value of < 0.05.

Results

In this study, only 119 (21.2%) of males (95% CI 17.8%, 24.8%) were involved in PMTCT of HIV. Being government employee (AOR = 3.73, 95%CI (2.169, 6.419)), had ever heard about PMTCT of HIV (AOR = 2.46, 95%CI (1.20, 5.02)), discussed with their partner (AOR = 3.11, 95%CI (1.43, 6.55)), partners’ who were informed the need to go PMTCT of HIV clinic (AOR = 2.45, 95%CI (1.17, 5.14)), Health workers friendly approach (AOR = 2.36, 95%CI (1.34, 4.15)), and long waiting time (AOR = 0.36, 95%CI (0.216, 0.610)) were found to be significantly associated with male involvement in PMTCT of HIV. Improving service provision including respectful care and health education on PMTCT of HIV for males and their partners shall be emphasized by the government.

Male involvement in prevention of mother to child transmission of human immunodeficiency virus and associated factors in Enebsiesarmider District, north West Ethiopia, 2018: a cross-sectional study

BACKGROUND

Globally, male involvement has been identified as a priority target area to be strengthened in the prevention of mother to child transmission (PMTCT) of HIV. However, there are limited studies on husband involvement in the prevention of mother to child transmission of HIV in Ethiopia. Therefore, this study aimed to assess male involvement in the prevention of mother to child transmission of HIV and associated factors among males whose wives gave birth in the last six months before the survey in Enebsiesarmider district, Northwest Ethiopia.

METHODS

A Community-based cross-sectional study was employed to assess male involvement in the prevention of mother to child transmission of human immunodeficiency virus and associated factors in Enebsiesarmider District, Northwest Ethiopia. The study was conducted from February 10-30, 2018. A total of 525 participants were involved in the study. A stratified cluster sampling method was used to recruit study participants. Data were collected using a structured interviewer-administered questionnaire. Data were entered using the epi Data software and exported to SPPS for analysis. Descriptive statistics including mean, a proportion were used to describe study variables. Multivariable logistic regression was employed to describe variables with the outcome variable.

RESULT

Overall male involvement in PMTCT was found to be 26.1% [95%CI, 22.1-29.5]. Respondents who have attended secondary education and above were more likely get involved in PMTCT than who have no formal education [AOR 2.45, 95%CI, 1.47-4.11], Respondents who have good knowledge on PMTCT [AOR 2.57, 95%CI, 1.58-4.18], good knowledge on ANC [AOR 2.10, 95%CI, 1.28-3.44], low cultural barriers [AOR 2.20, 95%CI, 1.34-3.63] low health system barriers [AOR 2.40, 95%CI, 1.37-4.20] were variables that significantly increase male involvement in PMTCT practices.

CONCLUSION

Male involvement in PMTCT was found to be low in the study area. Therefore, the district health office in collaboration with local health care providers shall design strategies for enhancing male involvement through creating a husband's knowledge regarding the merit of prevention of mother to child transmission through the provision of adequate information for all male partners at ANC clinic is recommended.

Rate of Couple HIV Testing in a Prenatal Care Clinic and Factors Associated with Refusal of Testing Among Male Partners

Objective

To determine the rate of HIV testing in couples during pregnancy and the reasons and risk factors related to male partners refusing to be tested.

Materials and methods

This was a cross-sectional study conducted in pregnant women undergoing prenatal care after receiving information about HIV testing on their first visit. After 20 weeks of gestation, they were approached to participate in the study, which consisted of an interview and examination of their medical records. Data collection included the women’s socioeconomic status, obstetric condition and serological test results together with their partner information. If relevant, the partner’s reasons for refusing to undergo HIV testing.

Results

A total of 400 pregnant women were recruited between February and August 2018, 150 (37.5%) of whose male partners underwent HIV testing. There were five couples in which one or both members were found to be positive for HIV: 1 seroconcordant couple, 1 serodiscordant couple in which the pregnant woman was positive, and 3 serodiscordant couples in which the male partners were positive. The most common reason for male partners refusing to take the test was their already having been tested once before. The women having had other sexual partners prior to their current partners was a significant risk factor for the partners refusing to be tested.

Conclusion

There was a low rate of couple HIV testing and a substantial portion of discordant infection among positive couples. Routine couples counseling and testing should be encouraged to reduce the vertical transmission and the number of new cases of HIV infection.

Mapping evidence of intervention strategies to improving men's uptake to HIV testing services in sub-Saharan Africa: A systematic scoping review

Background

HIV testing serves as a critical gateway for linkage and retention to care services, particularly in sub-Saharan African countries with high burden of HIV infections. However, the current progress towards addressing the first cascade of the 90–90-90 programme is largely contributed by women. This study aimed to map evidence on the intervention strategies to improve HIV uptake among men in sub-Saharan Africa.

Methods

We conducted a scoping review guided by Arksey and O’Malley’s (2005) framework and Levac et al. (2010) recommendation for methodological enhancement for scoping review studies. We searched for eligible articles from electronic databases such as PubMed/MEDLINE; American Doctoral Dissertations via EBSCO host; Union Catalogue of Theses and Dissertations (UCTD); SA ePublications via SABINET Online; World Cat Dissertations; Theses via OCLC; and Google Scholar. We included studies from January 1990 to August 2018. We used the PRISMA extension for scoping reviews (PRISMA-ScR): checklist and explanation. The Mixed Method Appraisal Tool version 2018 was used to determine the methodological quality of the included studies. We further used NVivo version 11 to aid with content thematic analysis.

Results

This study revealed that teaching men about HIV; Community-Based HIV testing; Home-Based HIV testing; Antenatal Care HIV testing; HIV testing incentives and HIV Self-testing are important strategies to improving HIV testing among men in sub-Saharan Africa. The need for improving programmes aimed at giving more information to men about HIV that are specifically tailored for men, especially given their poor uptake of HIV testing services was also found. This study further revealed the need for implementing Universal Test and Treat among HIV positive men found through community-based testing strategies, while suggesting the importance of restructuring home-based HIV testing visits to address the gap posed by mobile populations.

Conclusion

The community HIV testing, as well as, HIV self-testing strategies showed great potential to increase HIV uptake among men in sub-Saharan Africa. However, to address poor linkage to care, ART should be initiated soon after HIV diagnosis is concluded during community testing services. We also recommend more research aimed at addressing the quality of HIV self-testing kits, as well as, improving the monitoring systems of the distributed HIV self-testing kits.

Pregnancy outcomes and effects of antiretroviral drugs in HIV-positive pregnant women: a systematic review

Aim: Despite the clear morbidity, mortality and vertical transmission rates in women infected with HIV, there is still controversy surrounding the relationship between maternal infection and adverse neonatal outcomes. Antiretroviral therapy during pregnancy is considered the main and most effective method for reducing the vertical transmission of infection. However, there is no consensus over potential associations between antiretroviral therapy and adverse pregnancy outcomes. This systematic review focuses on the effects of antiretroviral drugs on pregnancy outcomes in HIV-positive women. Methods: After searching MEDLINE, the Cochrane Database of Systematic Reviews, the ISI Web of Sciences and EMBASE, 570 potentially eligible papers were identified. Only 32 papers were selected based on the inclusion criteria. Results: The most prevalent adverse pregnancy outcomes were low birth weight, preterm birth and stillbirth. Conclusion: Considering the higher prevalence of adverse pregnancy outcomes in HIV-infected women, HIV screening methods should be administered in all pregnant women. Appropriate treatment modalities should also be selected to minimize adverse pregnancy outcomes.

Providers' Perceptions of Couples' HIV Testing and Counseling (CHTC): Perspectives From a U.S. HIV Epicenter

Current epidemiology demonstrate the significance of couple-based HIV transmission among vulnerable U.S. populations and its contribution to health disparity in HIV prevalence. Couples HIV testing and counseling (CHTC) can be used to address couple-based HIV risk in the U.S. Though a globally recognized service, the literature lacks U.S.-based healthcare providers' (HCP) perspectives of CHTC. To address this research gap, a qualitative descriptive design was used to ascertain HCPs' perceptions about CHTC. Semi-structured in-depth interviews were conducted with 22 HCPs who were experienced with engaging patients or clients across the HIV care continuum. Overall, HCPs supported CHTC among different U.S.

POPULATIONS

Content and thematic analysis revealed HCPs perceived CHTC to be an evolution from current HIV testing approaches and a mechanism to screen people who may not otherwise. CHTC was perceived to have biomedical and bio-behavioral merit that warranted consideration for implementation within health service settings and among populations with heightened HIV risk. This strategy was perceived to be a mechanism for introducing PrEP and conception health into one's practice. CHTC also signaled patients reorienting perceptions of personal health as being linked to the health of another individual. Providers recognized that couples have evolved to be increasingly non-heteronormative and thought that CHTC should be offered to all couples. However, participants also noted that HCPs in the U.S. need to be comfortable with promoting sexual health among various populations for implementation of CHTC to be successful.

Couples HIV counselling and couple relationships in India, Georgia and the Dominican Republic

BACKGROUND

Couples HIV counseling and testing is essential for combination HIV prevention, but its uptake remains very low. We aimed to evaluate factors associated with couples HIV counseling uptake in India, Georgia and the Dominican Republic, as part of the ANRS 12127 Prenahtest intervention trial.

METHODS

Pregnant women ≥15 years, attending their first antenatal care (ANC) session between March and September 2009, self-reporting a stable partner, and having received couple-oriented post-test HIV counseling (trial intervention) were included. Individuals and couple characteristics associated with the acceptability of couples HIV counseling were assessed using multivariable logistic regression for each study site.

RESULTS

Among 711 women included (232, 240 and 239 in the Dominican Republic, Georgia and India, respectively), the uptake of couples HIV counseling was 9.1% in the Dominican Republic, 13.8% in Georgia and 36.8% in India. The uptake of couples HIV counseling was associated with women having been accompanied by their partner to ANC, and never having used a condom with their partner in the Dominican Republic; with women having been accompanied by their partner to ANC in India; with women having a higher educational level than their partner and having ever discussed HIV with their partner in Georgia.

CONCLUSION

Couple HIV counseling uptake was overall low. Strategies adapted to local socio-cultural contexts, aiming at improving women's education level, or tackling gender norms to facilitate the presence of men in reproductive health services, should be considered.

Thai national guidelines for the prevention of mother-to-child transmission of human immunodeficiency virus 2017

BACKGROUND

Thailand has made progress in reducing perinatal HIV transmission rates to levels that meet the World Health Organization targets for so-called "elimination" (<2%) of mother-to-child transmission (MTCT).

OBJECTIVES

To highlight the Thailand National Guidelines on HIV/AIDS Treatment Prevention Working Group issued a new version of its National Prevention of MTCT guidelines in March 2017 aimed to reduce MTCT rate to <1% by 2020.

DISCUSSION OF GUIDELINES

The guidelines include recommending initiation of antepartum antiretroviral therapy (ART) containing tenofovir disoproxil fumarate (TDF) plus lamivudine (3TC)/emtricitabine (FTC) plus efavirenz regardless of CD4 cell count as soon as HIV is diagnosed for ART naïve HIV-infected pregnant women. An alternative regimen is TDF or zidovudine (AZT) plus 3TC/FTC plus lopinavir/ritonavir (LPV/r) for HIV-infected pregnant women suspected resistant to non-nucleoside reverse transcriptase inhibitors. Treatment should be started immediately irrespective of gestational age and continued after delivery for life. Raltegravir is recommended in addition to the ART regimen for HIV-infected pregnant women who present late (gestational age (GA) ≥32 weeks) or those who have a viral load (VL) >1000 copies/mL at GA ≥32 weeks. HIV-infected pregnant women who conceive while receiving ART should continue their treatment regimen during pregnancy. HIV-infected pregnant women who present in labor and are not receiving ART should receive single-dose nevirapine immediately along with oral AZT, and continue ART for life. Infants born to HIV-infected mothers are categorized as high or standard risk for MTCT. High MTCT risk is defined as an infant whose mother has a viral load (VL) > 50 copies/mL at GA > 36 weeks or has received ART <12 weeks before delivery, or has poor ART adherence. These infants should be started on AZT plus 3TC plus NVP for 6 weeks after delivery. Infants with standard MTCT risk should receive AZT for 4 weeks. Formula feeding exclusively is recommended for all HIV-exposed infants.

Sexual partner testing for HIV to eliminate mother-to-child HIV transmission: a needs assessment in an urban hospital community clinic

OBJECTIVE

To characterize pregnant patients' knowledge, attitudes and preferences regarding antenatal HIV testing for themselves and their sexual partners.

STUDY DESIGN

Observational, mixed methods study of HIV-negative pregnant women from a university-based urban clinic. Participants completed an anonymous survey about HIV testing for themselves and their partners. Descriptive statistics, bivariable analyses, multivariable logistic regression and qualitative thematic analysis were utilized.

RESULTS

One hundred and forty-two patients (mean age 28.6±5.5 years) participated. A majority (57.7%) were married or partnered, and 92.9% reported having at least one current sexual partner. Although a majority (62.8%) reported their partner had a prior HIV test, and 93.0% of these women were aware of test results, only 20.7% reported partner testing had occurred in the past 6 months. Women who had a prior HIV test, who were older or who were non-white were more likely to be aware of their partner's HIV status. A majority (66.9%) of women desired knowledge of their partner's current status and 76.0% believed their partners would like to know his HIV status; in addition, 74% were interested in receiving partner testing at the site of prenatal care. Qualitative analysis demonstrated that health concerns and believing HIV knowledge is important to the relationship were motivators for desiring partner testing.

CONCLUSIONS

In this urban community, a majority of pregnant women do not know HIV test results of their sexual partner during the current pregnancy. Women desired to know their partner's HIV status and were receptive to partner testing at the site of prenatal care or other locations. Partner testing may be a critical step toward elimination of seroconversion during pregnancy and maternal-to-child HIV transmission.

Evaluation of a demand-creation intervention for couples' HIV testing services among married or cohabiting individuals in Rakai, Uganda: a cluster-randomized intervention trial

BACKGROUND

Uptake of couples' HIV counseling and testing (couples' HCT) services remains largely low in most settings. We report the effect of a demand-creation intervention trial on couples' HCT uptake among married or cohabiting individuals who had never received couples' HCT.

METHODS

This was a cluster-randomized intervention trial implemented in three study regions with differing HIV prevalence levels (range: 9-43 %) in Rakai district, southwestern Uganda, between February and September 2014. We randomly assigned six clusters (1:1) to receive the intervention or serve as the comparison arm using computer-generated random numbers. In the intervention clusters, individuals attended small group, couple and male-focused interactive sessions, reinforced with testimonies from 'expert couples', and received invitation coupons to test together with their partners at designated health facilities. In the comparison clusters, participants attended general adult health education sessions but received no invitation coupons. The primary outcome was couples' HCT uptake, measured 12 months post-baseline. Baseline data were collected between November 2013 and February 2014 while follow-up data were collected between March and April 2015. We conducted intention-to-treat analysis using a mixed effects Poisson regression model to assess for differences in couples' HCT uptake between the intervention and comparison clusters. Data analysis was conducted using STATA statistical software, version 14.1.

RESULTS

Of 2135 married or cohabiting individuals interviewed at baseline, 42 % (n = 846) had ever received couples' HCT. Of those who had never received couples' HCT (n = 1,174), 697 were interviewed in the intervention clusters while 477 were interviewed in the comparison clusters. 73.6 % (n = 513) of those interviewed in the intervention and 82.6 % (n = 394) of those interviewed in the comparison cluster were interviewed at follow-up. Of those interviewed, 72.3 % (n = 371) in the intervention and 65.2 % (n = 257) in the comparison clusters received HCT. Couples' HCT uptake was higher in the intervention than in the comparison clusters (20.3 % versus 13.7 %; adjusted prevalence ratio (aPR) = 1.43, 95 % CI: 1.02, 2.01, P = 0.04).

CONCLUSION

Our findings show that a small group, couple and male-focused, demand-creation intervention reinforced with testimonies from 'expert couples', improved uptake of couples' HCT in this rural setting.
