ABSTRACT
The Evidence Project conducts systematic reviews and meta-analyses of HIV behavioral interventions, behavioral aspects of biomedical interventions, combination prevention strategies, modes of service delivery, and integrated programs in low- and middle-income countries. Here, we present the overall protocol for our reviews. For each topic, we conduct a comprehensive search of five online databases, complemented by secondary reference searching. Articles are included if they are published in peer-reviewed journals and present pre/post or multi-arm data on outcomes of interest. Data are extracted from each included article by two trained coders working independently using standardized coding forms, with differences resolved by consensus. Risk of bias is assessed with the Evidence Project tool. Data are synthesized descriptively, and meta-analysis is conducted when there are similarly measured outcomes across studies. For over 20 years, this approach has allowed us to synthesize literature on the effectiveness of interventions and contribute to the global HIV response.

Women's ability to control their fertility and have the number of children they want when they want them is an internationally recognized human right. This right has been the driving force behind family planning programs in low- and middle-income countries for more than five decades. The HIV epidemic added greater urgency to those efforts once the risk of vertical transmission of the virus from mothers to their infants was recognized. In 2013, we published a systematic review of the evidence of effectiveness of family planning counseling for women living with HIV, emphasizing HIV related behaviors. In this updated review, we examined 23 studies, primarily from sub-Saharan Africa. The evidence we uncovered reflected efforts to integrate services provided to women. These showed that providing contraceptive services, including intensified counseling and support, in the HIV clinics where women living with HIV received their care increased the likelihood of subsequent use of modern contraception by as much as fourfold. These studies reflected a greater focus on women's family planning decisions and behaviors and less focus on HIV-related behaviors. Among the possible causes of this noted difference we include the widespread coverage of antiretroviral treatment for HIV. This advance has apparently changed the rationale and the approach to integrating family planning and HIV services in ways that may not have been fully appreciated. The results, however, are beneficial: greater coverage of family planning for women who wish to control their fertility and a more equal partnership between family planning services and HIV services in pursuit of the mutual goal of providing integrated services to meet women's needs.

BACKGROUND: Oral pre-exposure prophylaxis (PrEP) with emtricitabine/tenofovir disoproxil fumarate (F/TDF) has high efficacy against HIV-1 acquisition. Seventy-two prospective studies of daily oral F/TDF PrEP were conducted to evaluate HIV-1 incidence, drug resistance, adherence, and bone and renal safety in diverse settings. METHODS: HIV-1 incidence was calculated from incident HIV-1 diagnoses after PrEP initiation and within 60 days of discontinuation. Tenofovir concentration in dried blood spots (DBS), drug resistance, and bone/renal safety indicators were evaluated in a subset of studies. RESULTS: Among 17,274 participants, there were 101 cases with new HIV-1 diagnosis (0.77 per 100 person-years; 95% CI 0.63-0.94). In 78 cases with resistance data, 18 (23%) had M184I or V, one (1.3%) had K65R, and three (3.8%) had both mutations. In 54 cases with tenofovir concentration data from DBS, 45 (83.3%), 2 (3.7%), 6 (11.1%), and 1 (1.9%) had average adherence of <2, 2-3, 4-6, and ≥7 doses/week, respectively, and the corresponding incidence was 3.9 (95% CI 2.9-5.3), 0.24 (0.060-0.95), 0.27 (0.12-0.60), and 0.054 (0.008-0.38) per 100 person-years. Adherence was low in younger participants, Hispanic/Latinx and Black participants, cisgender women, and transgender women. Bone and renal adverse event incidence rates were 0.69 and 11.8 per 100 person-years, respectively, consistent with previous reports. CONCLUSIONS: Leveraging the largest pooled analysis of global PrEP studies to date, we demonstrate that F/TDF is safe and highly effective, even with less than daily dosing, in diverse clinical settings, geographies, populations, and routes of HIV-1 exposure.
ABSTRACT
BACKGROUND: The HITSystem efficacy trial showed significant improvements in early infant diagnosis retention, return and notification of infant test results, and earlier antiretroviral therapy (ART) initiation compared with standard-of-care early infant diagnosis services in Kenya. This study aimed to analyse data from the HITSystem trial to assess the cost-effectiveness of the intervention in Kenya. METHODS: In this analysis, we extrapolated results from the HITSystem cluster randomised controlled trial to model early infant diagnosis outcomes and cost-effectiveness if the HITSystem was scaled up nationally in Kenya, compared with standard-of-care outcomes. We used a micro-costing method to collect cost data, which were analysed from a health-system perspective, reflecting the investment required to add HITSystem to existing early infant diagnosis services and infrastructure. The base model used to calculate cost-effectiveness was deterministic and calculated the progression of infants through early infant diagnosis. Differences in progression across study arms were used to establish efficacy outcomes. The number of life-years gained per infant successfully initiating ART were based on the Cost Effectiveness of Preventing AIDS Complications model in east Africa. HITSystem cost data were integrated into the model, and the incremental cost-effectiveness ratio was calculated in terms of cost per life-year gained. Sensitivity analyses were done using the deterministic model with triangular stochastic probability functions for key model parameters added. The number of life-years gained was discounted at 3% and costs were adjusted to 2021 values. FINDINGS: The cost per life-year gained from the HITSystem was US$82·72. Total cost for national HITSystem coverage in Kenya was estimated to be around $2·6 million; covering 82â230 infants exposed to HIV at a cost of $31·38 per infant and a yield of 1133 infants receiving timely ART, which would result in 31â189 life-years gained. With sensitivity analyses, the cost per life-year gained varied from $40·13 to $215·05. 90% of model values across iterations ranged between $55·58 (lower 5% threshold) and $132·38 (upper 95% threshold). INTERPRETATION: The HITSystem would be very cost-effective in Kenya and can optimise the return on the existing investment in the national early infant diagnosis programme.

We conducted a systematic review and meta-analysis of the impact of needle and syringe exchange programs (NSP) on both individual- and community-level needle-sharing behaviors and other HIV-related outcomes in low- and middle-income countries (LMIC). A search of five databases for peer-reviewed trial or quasi-experimental studies reported through July 2021 identified 42 interventions delivered in 35 studies, with a total of 56,751 participants meeting inclusion criteria. Random-effects meta-analysis showed a significant protective association between NSP exposure and needle-sharing behaviors at the individual-level (odds ratio [OR] = 0.25, 95% confidence interval [CI] = 0.16-0.39, 8 trials, n = 3947) and community-level (OR 0.39, CI 0.22-0.69, 12 trials, n = 6850), although with significant heterogeneity. When stratified by needle-sharing directionality, NSP exposure remained associated with reduced receptive sharing, but not distributive sharing. NSP exposure was also associated with reduced HIV incidence and increased HIV testing but there were no consistent associations with prevalence of bloodborne infections. Current evidence suggests positive impacts of NSPs in LMICs.
RESUMEN: Realizamos una revisión sistemática y un metanálisis del impacto de los programas de intercambio de agujas y jeringas (NSP, por sus siglas en inglés) de los comportamientos de uso compartido de agujas tanto a nivel individual como comunitario y otros resultados relacionados con el VIH en países de ingresos bajos y medianos (LMIC, por sus siglas en inglés). Realizamos búsquedas sistemáticas en cinco bases de datos hasta julio de 2021 en busca de ensayos revisados por pares o estudios cuasiexperimentales. En general, 42 intervenciones informadas en 35 estudios entre 56 751 participantes cumplieron los criterios de inclusión. El metanálisis de efectos aleatorios de ocho estudios a nivel individual y 12 a nivel comunitario con 11 075 participantes en total mostró una asociación protectora significativa entre la exposición a NSP y los comportamientos de compartir agujas (individual: OR 0,25, IC95%: 0,160,39; comunidad: OR 0,39, IC95%:0,220,69), aunque con una heterogeneidad importante. Cuando se estratificó por la direccionalidad del intercambio de agujas, la exposición a NSP permaneció asociada con un intercambio receptivo reducido, pero no con un intercambio distributivo. La exposición a NSP también se asoció con una incidencia reducida del VIH y un aumento de las pruebas del VIH, pero no hubo asociaciones consistentes para la prevalencia de infecciones transmitidas por la sangre. La evidencia actual sugiere impactos positivos de los NSP en los LMIC.

BACKGROUND: Men experience twice the mortality of women while on ART in sub-Saharan Africa (SSA) largely due to late HIV diagnosis and poor retention. Here we propose to conduct an individually randomized control trial (RCT) to investigate the impact of three-month home-based ART (hbART) on viral suppression among men who were not engaged in care. METHODS AND DESIGN: A programmatic, individually randomized non-blinded, non-inferiority-controlled trial design (ClinicalTrials.org NCT04858243). Through medical chart reviews we will identify "non-engaged" men living with HIV, ≥15years of age who are not currently engaged in ART care, including (1) men who have tested HIV-positive and have not initiated ART within 7 days; (2) men who have initiated ART but are at risk of immediate default; and (3) men who have defaulted from ART. With 1:1 computer block randomization to either hbART or facility-based ART (fbART) arms, we will recruit men from 10-15 high-burden health facilities in central and southern Malawi. The hbART intervention will consist of 3 home-visits in a 3-month period by a certified male study nurse ART provider. In the fbART arm, male participants will be offered counselling at male participant's home, or a nearby location that is preferred by participants, followed with an escort to the local health facility and facility navigation. The primary outcome is the proportion of men who are virally suppressed at 6-months after ART initiation. Assuming primary outcome achievement of 24.0% and 33.6% in the two arms, 350 men per arm will provide 80% power to detect the stated difference. DISCUSSION: Identifying effective ART strategies that are convenient and accessible for men in SSA is a priority in the HIV world. Men may not (re-)engage in facility-based care due to a myriad of barriers. Two previous trials investigated the impact of hbART on viral suppression in the general population whereas this trial focuses on men. Additionally, this trial involves a longer duration of hbART i.e., three months compared to two weeks allowing men more time to overcome the initial psychological denial of taking ART.

Background. Across settings, individuals from populations that are multiply stigmatized are at increased risk of HIV and experience worse HIV treatment outcomes. As evidence expands on how intersecting stigmatized identities and conditions influence HIV outcomes, researchers have used diverse quantitative approaches to measure HIV-related intersectional stigma and discrimination. To date, no clear consensus exists regarding how to best quantitatively measure and analyze intersectional stigma and discrimination. Objectives. To review and document existing quantitative measures of HIV-related intersectional stigma and discrimination to inform research, programmatic, and policy efforts. Search Methods. We searched 5 electronic databases for relevant studies. References of included articles were screened for possible inclusion. Additional articles were screened on the basis of consultations with experts in the field. Selection Criteria. We included peer-reviewed studies published between January 1, 2010, and May 12, 2021, that were HIV related and presented 1 or more quantitative measures of stigma and discrimination using an intersectional lens in measure design or analysis. Data Collection and Analysis. Systematic methods were used to screen citations and abstract data via a standardized coding form. Data were analyzed by coding categories stratified according to 2 subgroups: (1) studies incorporating a single intersectional measure and (2) studies that examined intersectional stigma through analytical approaches combining multiple measures. Main Results. Sixteen articles met the inclusion criteria, 7 of which explicitly referenced intersectionality. Ten studies were from the United States. All of the studies included participants living with HIV. Among the 4 studies incorporating a single intersectional stigma measure, 3 explored race and gender stigma and 1 explored gender and HIV stigma. Studies involving analytic approaches (n = 12) mostly examined intersectional stigma via interaction terms in multivariate regression models. Three studies employed structural equation modeling to examine interactive effects or latent constructs of intersectional stigma. Conclusions. Research on the measurement of HIV-related intersectional stigma and discrimination is currently concentrated in high-income settings and generally focuses on the intersection of 2 identities (e.g., race and gender). Efforts are needed to expand appropriate application of intersectionality in the development, adaptation, and use of measures of HIV-related intersectional stigma and discrimination. The use of context-, identity-, or condition-adaptable measures should be considered. Researchers should also carefully consider how to meaningfully engage communities in the process of measurement development. Public Health Implications. The measures and analytic approaches presented could significantly enhance public health efforts in assessing the impact of HIV-related intersectional stigma and discrimination on critical health outcomes.

If sexual partner concurrency drives HIV transmission dynamics, shouldn't HIV prevention efforts be addressing this behavior? We systematically reviewed studies evaluating interventions to reduce sexual partner concurrency in low- and middle-income countries using pre/post or multi-arm designs. Only two studies met our inclusion criteria; neither found significant differences by intervention exposure on self-reported concurrency. Overall, very few interventions have specifically targeted concurrency, and those that did have not been rigorously evaluated. In practice, concurrency may be difficult to separate from multiple partnerships more generally.

Introduction: Heterosexual couples are at high risk for HIV acquisition in sub-Saharan Africa, and HIV self-testing (HST) is an additional approach to expand access to HIV testing services. However, it is not well known how gender equality is associated with HST.Methods: We used intervention-arm data from a cluster-randomised controlled HST intervention trial (N = 1 618) conducted in Uganda to determine the association between attitudes towards intimate partner violence (IPV), decision-making power and male partner's uptake of HST among heterosexual couples expecting a child in south-central Uganda. The original study question was to assess the impact of providing pregnant women with HST kits to improve male partner's HIV testing rates. For this analysis, the primary exposures were gender equality (measured by male partner's and female partner's attitudes towards IPV and the female partner's household decision-making power), and the primary outcome was the male partner's uptake of HST. Multivariate logistic regression was used for analysis.Results: We found that male partner HST uptake did not vary depending on male partner's attitudes towards IPV or decision-making power; however, male partner HST uptake did depend on the female partner's attitude towards IPV, with 1.76 times more testing (95% CI 1.06-2.92) in couples where the woman had "medium" versus "high" acceptance of IPV, and 1.82 times more testing (95% CI 1.08-3.08) in couples where the woman had "low" versus "high" acceptance of IPV.Conclusions: This study shows the importance of appropriate negative attitudes by women to IPV in increasing male partner's HST uptake to integrate HST into national health care policies.

BACKGROUND: A substantial number of new HIV infections in sub-Saharan Africa occur within stable couples. Biomedical prevention (pre-exposure prophylaxis, PrEP) and treatment (antiretroviral therapy, ART) can provide benefits to sexual partners and can be used to prevent infection within HIV serodiscordant couples. However, research is typically focused on individuals, not dyads, even when the intervention may directly or indirectly impact sexual partners. Gaps remain in understanding best practices for recruitment, informed consent, and intervention implementation in studies involving HIV prevention and treatment among heterosexual serodiscordant couples. This qualitative study was undertaken to understand and describe decision-making and dyadic-level influence among members of serodiscordant couples regarding (1) participation in a dyadic-based research study involving HIV self-testing and access to PrEP, and (2) utilization of PrEP and ART. METHODS: This qualitative study was nested within an observational cohort study assessing the acceptability of home-based couples' HIV self-testing and uptake of dyadic care for serodiscordant couples involving facilitated referral for HIV-positive partners and access to PrEP for HIV-negative partners. Semi-structured in-depth interviews were conducted among a subset of study participants (n = 22) as well as individuals involved in serodiscordant relationships who chose not to participate (n = 9). Interviews focused on couples' decision-making regarding study participation and dyadic-level influence on medication use. Interviews were transcribed verbatim and translated from Kiswahili into English. Data were analyzed using thematic analysis. RESULTS: Three major themes were identified: (1) HIV as "two people's secret" and the elevated role of partner support in serodiscordant relationships; (2) the intersectional role of HIV-status and gender on decision-making; (3) the relational benefits of PrEP, including psychosocial benefits for the couple that extend beyond prevention. CONCLUSIONS: The study found that couples made joint decisions regarding study participation and uptake of HIV-related medication. Relational autonomy and dyadic-level influence should be considered within research and programs involving HIV serodiscordant couples.

BACKGROUND: Economic compensation interventions may help support higher voluntary medical male circumcision (VMMC) coverage in priority sub-Saharan African countries. To inform World Health Organization guidelines, we conducted a systematic review of economic compensation interventions to increase VMMC uptake. METHODS: Economic compensation interventions were defined as providing money or in-kind compensation, reimbursement for associated costs (e.g. travel, lost wages), or lottery entry. We searched five electronic databases and four scientific conferences for studies examining the impact of such interventions on VMMC uptake, HIV testing and safer-sex/risk-reduction counseling uptake within VMMC, community expectations about compensation, and potential coercion. We screened citations, extracted data, and assessed risk of bias in duplicate. We conducted random-effects meta-analysis. We also reviewed studies examining acceptability, values/preferences, costs, and feasibility. RESULTS: Of 2484 citations identified, five randomized controlled trials (RCTs) and three non-randomized controlled trials met our eligibility criteria. Studies took place in Kenya, Malawi, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe. Meta-analysis of four RCTs showed significant impact of any economic compensation on VMMC uptake (relative risk: 5.23, 95% CI: 3.13 to 8.76). RCTs of food/transport vouchers and conditional cash transfers generally showed increases in VMMC uptake, but lotteries, subsidized VMMC, and receiving a gift appeared somewhat less effective. Three non-randomized trials showed mixed impact. Six additional studies suggested economic compensation interventions were generally acceptable, valued for addressing key barriers, and motivating to men. However, some participants felt they were insufficiently motivating or necessary; one study suggested they might raise community suspicions. One study from South Africa found a program cost of US$91 per additional circumcision and US$450-$1350 per HIV infection averted. CONCLUSIONS: Economic compensation interventions, particularly transport/food vouchers, positively impacted VMMC uptake among adult men and were generally acceptable to potential clients. Carefully selected economic interventions may be a useful targeted strategy to enhance VMMC coverage.

BACKGROUND: Voluntary medical male circumcision (VMMC) remains an essential component of combination HIV prevention services, particularly in priority countries in sub-Saharan Africa. As VMMC programs seek to maximize impact and efficiency, and to support World Health Organization guidance, specific uptake-enhancing strategies are critical to identify. METHODS: We systematically reviewed the literature to evaluate the impact of service delivery interventions (e.g., facility layout, service co-location, mobile outreach) on VMMC uptake among adolescent and adult men. For the main effectiveness review, we searched for publications or conference abstracts that measured VMMC uptake or uptake of HIV testing or risk reduction counselling within VMMC services. We synthesized data by coding categories and outcomes. We also reviewed studies assessing acceptability, values/preferences, costs, and feasibility. RESULTS: Four randomized controlled trials and five observational studies were included in the effectiveness review. Studies took place in South Africa, Tanzania, Uganda, Zambia, and Zimbabwe. They assessed a range of service delivery innovations, including community-, school-, and facility-based interventions. Overall, interventions increased VMMC uptake; some successfully improved uptake among age-specific subpopulations, but urban-rural stratification showed no clear trends. Interventions that increased adult men's uptake included mobile services (compared to static facilities), home-based testing with active referral follow-up, and facility-based HIV testing with enhanced comprehensive sexual education. Six acceptability studies suggested interventions were generally perceived to help men choose to get circumcised. Eleven cost studies suggested interventions create economies-of-scale and efficiencies. Three studies suggested such interventions were feasible, improving facility preparedness, service quality and quantity, and efficiencies. CONCLUSIONS: Innovative changes in male-centered VMMC services can improve adult men's and adolescent boys' VMMC uptake. Limited evidence on interventions that enhance access and acceptability show promising results, but evidence gaps persist due to inconsistent intervention definition and delivery, due in part to contextual relevance and limited age disaggregation.

Communication between sexual partners is an important component of HIV prevention and occurs within a broader context of socio-culturally defined gender norms and dynamics. We analyzed cross-sectional data from a community-based random sample of men and women living in Kisarawe, Tanzania to understand factors related to partner communication about HIV. Bivariate and multivariate logistic regression analyses, disaggregated by gender, included variables at the individual-, relational-, and community-levels. Individuals who knew their HIV-positive status prior to the study were excluded as the focus was on risk communication, not HIV status disclosure. Of 524 participants, 129 women (43.3%) and 96 men (42.5%) reported HIV-related communication with their most recent sexual partner. For women but not men, individual-level socioeconomic factors-including education, possession of a household radio, and employment-and relational-level factors-including partner age and type-were significantly associated with partner communication. At the community level, being socially engaged was positively correlated with partner communication across genders (aOR = 2.02, 95% CI 1.05-3.89, p = 0.03 for men and aOR = 1.74, 95% CI 1.03-2.95, p = 0.04 for women). For women, having less discriminatory attitudes toward people living with HIV and favorable perceived norms of HIV-related communication were significantly associated with partner communication. For men, agreeing that women should be allowed to work outside the home was significantly correlated with partner communication (aOR = 6.02, 95% CI 2.23-16.24, p < 0.001). Findings suggest a link between gender dynamics and partner communication, with individual and relational factors being associated with communication for women and community-level factors being associated with communication for both genders.

OBJECTIVE: To update the prior systematic review from studies published in the past 9 years that examine the effects of condom social marketing (CSM) programs on condom use in low- and middle-income countries. DATA SOURCES: PubMed, CINAHL, PsycINFO, Sociological Abstracts, and EMBASE. Hand searching of AIDS, AIDS and Behavior, AIDS Care, and AIDS Education and Prevention. STUDY INCLUSION AND EXCLUSION CRITERIA: (a) Published from 1990 to January 16, 2019, (b) low- or middle-income country, (c) evaluated CSM, (d) analyses across preintervention to postintervention exposure or across multiple study arms, (e) measured condom use behavior, and (f) sought to prevent HIV transmission. DATA EXTRACTION: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, 2 reviewers extracted citation, inclusion criteria, methods, study population, setting, sampling, study design, unit of analysis, loss to follow-up, comparison group characteristics, intervention characteristics, and eligible outcome results. DATA SYNTHESIS: The 2012 review found 6 studies (combined N = 23 048). In a meta-analysis, the pooled odds ratio for condom use was 2.01 (95% confidence interval [CI]: 1.42-2.84) for the most recent sexual encounter and 2.10 (95% CI: 1.51-2.91) for a composite of all condom use outcomes. Studies had significant methodological limitations. Of 518 possible new citations identified in the update, no new articles met our inclusion criteria. CONCLUSIONS: More studies are needed with stronger methodological rigor to help provide evidence for the continued use of this approach globally. There is a dearth of studies over the past decade on the effectiveness of CSM in increasing condom use in low- and middle-income countries (LMIC).

BACKGROUND: Gender inequality is a pervasive problem in sub-Saharan Africa, and has negative effects on health and development. OBJECTIVE: Here, we sought to identify socioeconomic predictors of gender inequality (measured by low decision-making power and high acceptance of intimate partner violence) within heterosexual couples expecting a child in south-central Uganda. METHOD: We used data from a two-arm cluster randomized controlled HIV self-testing intervention trial conducted in three antenatal clinics in south-central Uganda among 1,618 enrolled women and 1,198 male partners. Analysis included Cochran Mantel-Haenzel, proportional odds models, logistic regression, and generalized linear mixed model framework to account for site-level clustering. RESULTS: Overall, we found that 31.1% of men had high acceptance of IPV, and 15.9% of women had low decision-making power. We found religion, education, HIV status, age, and marital status to significantly predict gender equality. Specifically, we observed lower gender equality among Catholics, those with lower education, those who were married, HIV positive women, and older women. CONCLUSION: By better understanding the prevalence and predictors of gender inequality, this knowledge will allow us to better target interventions (increasing education, reducing HIV prevalence in women, targeting interventions different religions and married couples) to decrease inequalities and improve health care delivery to underserved populations in Uganda.

BACKGROUND: Higher gender equality is associated with many human immunodeficiency virus (HIV) preventive behaviors, including HIV testing. HIV self-testing is a relatively new testing technology that could assist with HIV prevention. However, there are no studies examining gender equality and HIV self-testing. We examined the associations between gender equality and couples' uptake of HIV self-testing among heterosexual couples expecting a child in central Kenya. METHODS: This analysis used data from a HIV self-testing randomized intervention trial among pregnant women attending antenatal care and their male partners. The primary exposures were gender equality (measured by the male partner's attitudes toward intimate partner violence, and the woman's report on her household decision making power), and the primary outcome was couples' uptake of HIV self-testing. Generalized linear mixed models framework was used to account for site-level clustering. RESULTS: In comparison to male partners reporting high acceptance of intimate partner violence, couples with male partners reporting medium acceptance (odds ratio, 2.36; 95% confidence interval, 0.99-5.63) or low acceptance (odds ratio, 2.50; 95% confidence interval, 1.20-5.21) were significantly more likely to use HIV self-testing. Gender equality measured by decision making power was not associated with couples' uptake of HIV self-testing. CONCLUSIONS: This study is the first of its kind to examine the association between gender equality and couples' HIV self-testing. This holds important implications for HIV self-testing as we strive to achieve the United Nations Programme on HIV/acquired immune deficiency syndrome goal that 90% of individuals living with HIV should know their status.

BACKGROUND: Different tools exist for assessing risk of bias of intervention studies for systematic reviews. We present a tool for assessing risk of bias across both randomized and non-randomized study designs. The tool was developed by the Evidence Project, which conducts systematic reviews and meta-analyses of behavioral interventions for HIV in low- and middle-income countries. METHODS: We present the eight items of the tool and describe considerations for each and for the tool as a whole. We then evaluate reliability of the tool by presenting inter-rater reliability for 125 selected studies from seven published reviews, calculating a kappa for each individual item and a weighted kappa for the total count of items. RESULTS: The tool includes eight items, each of which is rated as being present (yes) or not present (no) and, for some items, not applicable or not reported. The items include (1) cohort, (2) control or comparison group, (3) pre-post intervention data, (4) random assignment of participants to the intervention, (5) random selection of participants for assessment, (6) follow-up rate of 80% or more, (7) comparison groups equivalent on sociodemographics, and (8) comparison groups equivalent at baseline on outcome measures. Together, items (1)-(3) summarize the study design, while the remaining items consider other common elements of study rigor. Inter-rater reliability was moderate to substantial for all items, ranging from 0.41 to 0.80 (median κ = 0.66). Agreement between raters on the total count of items endorsed was also substantial (κw = 0.66). CONCLUSIONS: Strengths of the tool include its applicability to a range of study designs, from randomized trials to various types of observational and quasi-experimental studies. It is relatively easy to use and interpret and can be applied to a range of review topics without adaptation, facilitating comparability across reviews. Limitations include the lack of potentially relevant items measured in other tools and potential threats to validity of some items. To date, the tool has been applied in over 30 reviews. We believe it is a practical option for assessing risk of bias in systematic reviews of interventions that include a range of study designs.

Imbalance of power and equality in sexual relationships is linked to health in various ways, including (1) reduced ability to get information or take action, (2) increased violence between partners, and (3) influence on the reduced use of health services. While there has been research assessing multiple social and economic variables related to gender inequality, studies have used many different definitions of gender inequality, and there is a lack of this research within a pregnancy context. Here, we attempt to identify social and economic predictors of gender inequality (measured by decision-making power and acceptance of intimate partner violence) within heterosexual couples expecting a child in central Kenya. We ran a secondary data analysis using data from a three-arm individually randomized controlled HIV self-testing intervention trial conducted in 14 antenatal clinics in central and eastern Kenya among 1410 women and their male partners. The analysis included Cochran Mantel-Haenszel, logistic regression, proportional odds models, and generalized linear mixed model (GLMM) framework to account for site-level clustering. Overall, we show that there are significant social and economic variables associated with acceptance of intimate partner violence including higher age, being married, "other" religion, lower partner education, higher wealth status, and variables associated with decision-making power including lower partner education and lack of equality in earnings. This study contributes to the literature on the influence of social and economic factors on gender inequality, especially in Kenya which has a high burden of HIV/AIDS. Our results show some areas to improve these specific factors (including education and employment opportunities) or create interventions for targeted populations to potentially improve gender equality in heterosexual pregnant couples in Kenya.
