Background: Public health initiatives must look for ways to cost-effectively scale critical interventions to achieve high coverage. Private sector distribution channels, can potentially distribute preventive healthcare products to hard-to-reach populations, decongest public healthcare systems, and increase the sustainability of programs by getting customers to share costs. However, little is known about how sellers set prices for new products. By introducing a new product, HIV self-test kits, to local drug shops, we observed whether shops experimented with pricing, charged different buyers different prices, and whether prices converged within the local market over our study period., Methods: From August to December 2019, we provided free HIV self-test kits, a new product, to 26 drug shops in Shinyanga, Tanzania to sell to the local community. We measured sales volume, price, customer age and sex using shop records. Using a multiple linear regression model, we conducted F-tests to determine whether shop, age, sex, and time (week) respectively were associated with price. We measured willingness-to-pay to restock test kits at the end of the study., Results: 514 test kits were sold over 18 weeks; 69% of buyers were male, 40% were aged 25-34 and 32% aged 35-44. Purchase prices ranged from 1000 to 6000 Tsh (median 3000 Tsh; ~$1.30 USD). Within shops, prices were 11.3% higher for 25-34 and 12.7% higher for 45+ year olds relative to 15-19-year olds (p = 0.029) and 13.5% lower for men (p = 0.023) on average. Although prices varied between shops, prices varied little within shops over time, and did not converge over the study period or cluster geospatially. Mean maximum willingness-to-pay to restock was 2000 Tsh per kit., Conclusions: Shopkeepers charged buyers different prices depending on buyers' age and sex. There was limited variation in prices within shops over time and low demand among shopkeepers to restock at the end of the study. Given the subsidized global wholesale price ($2 USD or ~ 4600 Tsh), further demand creation and/or cost-reduction is required before HIV self-test kits can become commercially viable in drug shops in this setting. Careful consideration is needed to align the motivations of retailers with public health priorities while meeting their private for-profit needs.

Background: HIV risk remains high among adolescent girls and young women (AGYW, ages 15-24) in Tanzania. Many AGYW experience stigma and provider bias at health facilities, deterring their use of HIV prevention services. Privately-owned drug shops, ubiquitous in many communities, may be an effective and accessible channel to deliver HIV prevention products to AGYW, including oral pre-exposure prophylaxis (PrEP) and the dapivirine vaginal ring., Methods: In July-August 2019, we enrolled 26 drug shops in Shinyanga, Tanzania in an ongoing study to create "girl-friendly" drug shops where AGYW can access HIV self-testing and contraception. At baseline, all shop dispensers were given basic information about oral PrEP and the dapivirine ring and were asked about their interest in stocking each. During the next 3-5 months, we surveyed AGYW (n = 56) customers about their interest in oral PrEP and the ring., Results: Among dispensers, the median age was 42 years and 77% were female. Overall, 42% of dispensers had heard of a medication for HIV prevention. Almost all dispensers reported some interest in stocking oral PrEP (92%) and the dapivirine ring (96%). Most (85%) reported they would provide oral PrEP to AGYW who requested it. Among AGYW customers, the median age was 17 years; 29% of AGYW were married or had a steady partner and 18% had children. Only 20% of AGYW had heard of a medication to prevent HIV, yet 64% and 43% expressed some interest in using oral PrEP and the dapivirine ring, respectively, after receiving information about the products. PrEP interest was higher among AGYW who were partnered and had children., Conclusions: Despite low prior awareness of PrEP among shop dispensers and AGYW, we found high levels of interest in oral PrEP and the dapivirine ring in both groups. Community-based drug shops represent a promising strategy to make HIV prevention more accessible to AGYW.

Transportation cost is a barrier to HIV treatment, yet no studies have examined its association with contraceptive use among women living with HIV. We analyzed cross-sectional data from women attending three public healthcare facilities in Shinyanga, Tanzania where they initiated antiretroviral therapy for HIV infection in the previous 90 days; all facilities offered free contraception. Women self-reported current contraceptive use and the round-trip cost of transportation to the facility. Among 421 women aged 18-49, 86 (20.4%) were using any modern contraceptive method, of which half were using modern methods other than condoms. Women who paid more than 2,000 Tanzanian shillings for transportation had a significantly lower prevalence of any modern method use than women who paid nothing (9.1% vs. 21.3%; adjusted difference: -12.9; 95% confidence interval: -21.3, -4.4). A similar difference was observed for non-condom modern method use. We conclude that high transportation cost may impede contraceptive use even among women accessing HIV treatment.

Heavy load carrying of water, firewood, and sand/stones is a ubiquitous activity for women living in developing countries. Although the intra-abdominal pressure associated with heavy load carrying is hypothesized to increase the risk of pelvic organ prolapse (POP) among women, relevant epidemiologic data are lacking. We conducted a comparative study involving two exploratory cross-sectional studies among convenience samples of women carrying heavy loads, with different characteristics: (1) as part of their activities for daily living, in Shinyanga region, Tanzania; and (2) working as sand miners in Pokhara, Nepal. Women were categorized has having "low" or "high" load-carrying exposures based on the measured weights of the loads being carried at the time of the survey, as well as on self-reported duration and frequency of load carrying. A summary score for lower abdominal discomfort suggestive of POP was generated using questions from the Pelvic Organ Prolapse Distress Inventory (POPDI-6). Women with higher load carrying exposures had on average higher discomfort scores in both Tanzania (adjusted prevalence difference (PD a ) = 3.7; 95% CI: -3.8-11.3; p = 0.33) and Nepal (PD a = 9.3; 95% CI: -4.9-23.6; p = 0.18). We identified trends suggestive of an association between increasing heavy load carrying exposures and symptoms of lower abdominal discomfort. Our findings underscore the need for larger epidemiologic studies of the potential adverse reproductive health effects of heavy load carrying activities on women in developing countries.

Background: Financial incentives promote use of HIV services and might support adherence to the sustained antiretroviral therapy (ART) necessary for viral suppression, but few studies have assessed a biomarker of adherence or evaluated optimal implementation. We sought to determine whether varying sized financial incentives for clinic attendance effected viral suppression in patients starting ART in Tanzania., Methods: In a three-arm, parallel-group, randomised controlled trial at four health facilities in Shinyanga region, Tanzania, adults aged 18 years or older with HIV who had started ART within the past 30 days were randomly assigned (1:1:1) using a tablet-based application (stratified by site) to receive usual care (control group) or to receive a cash incentive for monthly clinic attendance in one of two amounts: 10 000 Tanzanian Shillings (TZS; about US$4·50) or 22 500 TZS (about $10·00). There were no formal exclusion criteria. Participants were masked to the existence of two incentive sizes. Incentives were provided for up to 6 months via mobile health technology (mHealth) that linked biometric attendance monitoring to automated mobile payments. We evaluated the primary outcome of retention in care with viral suppression (<1000 copies per mL) at 6 months using logistic regression. This trial is registered with ClinicalTrials.gov, NCT03351556., Findings: Between April 24 and Dec 14, 2018, 530 participants were randomly assigned to an incentive strategy (184 in the control group, 172 in the smaller incentive group, and 174 in the larger incentive group). All participants were included in the primary intention-to-treat analysis. At 6 months, approximately 134 (73%) participants in the control group remained in care and had viral suppression, compared with 143 (83%) in the smaller incentive group (risk difference [RD] 9·8, 95% CI 1·2 to 18·5) and 150 (86%) in the larger incentive group (RD 13·0, 4·5 to 21·5); we identified a positive trend between incentive size and viral suppression (p trend=0·0032), although the incentive groups did not significantly differ (RD 3·2, -4·6 to 11·0). Adverse events included seven (4%) deaths in the control group and 11 (3%) deaths in the intervention groups, none related to study participation., Interpretation: Small financial incentives delivered using mHealth can improve retention in care and viral suppression in adults starting HIV treatment. Although further research should investigate the durability of effects from short-term incentives, these findings strengthen the evidence for implementing financial incentives within standard HIV care., Funding: National Institute of Mental Health at the US National Institutes of Health., (Copyright © 2020 Elsevier Ltd.

Foreign-born persons living in the US have an increased risk of exposure to HIV and higher rates of HIV diagnosis (Patel-Larson et al. in Poster presented at the 2007 National HIV Prevention Conference, pp 2-5, 2007; Prosser et al. in JAMA 308:601-607, 2012). Foreign-born persons also tend to live in areas with high concentration of immigrants and more often neighborhoods of high poverty, for at least some time (Jargowsky in J Ethn Migr Stud 35:1129-1151, 2009). Using HIV surveillance data in Alameda County, California, we examined whether the association between immigrant status and the four outcomes on the HIV care cascade (late diagnosis, linkage to care within 30 days of diagnosis, retention in HIV care, and viral load status a year after diagnosis) differed by census tract poverty level. We used generalized estimating equations (GEE) adjusted for sex at birth, age, race, and transmission mode. Of 1235 individuals with HIV diagnosis reported between 2011 and 2016, 29% were foreign-born. Foreign-born status was significantly associated with late HIV diagnosis but not with linkage, retention in care, and achievement of undetectable viral load a year after diagnosis. Neighborhood poverty modified the association between immigrant status and retention in care, but not late diagnosis, linkage or viral load status. Our findings suggest that neighborhood resources may buffer against disparities in retention. Thus, immigrants in poorer neighborhoods may require more support to stay in care.

Introduction: Despite improvements in prevention of mother-to-child transmission (PMTCT) of HIV outcomes, there remain unacceptably high numbers of mother-to-child transmissions (MTCT) of HIV. Programmes and research collect multiple sources of PMTCT data, yet this data is rarely integrated in a systematic way. We conducted a data integration exercise to evaluate the Zimbabwe national PMTCT programme and derive lessons for strengthening implementation and documentation., Methods: We used data from four sources: research, Ministry of Health and Child Care (MOHCC) programme, Implementer - Organization for Public Health Interventions and Development, and modelling. Research data came from serial population representative cross-sectional surveys that evaluated the national PMTCT programme in 2012, 2014 and 2017/2018. MOHCC and Organization for Public Health Interventions and Development collected data with similar indicators for the period 2018 to 2019. Modelling data from 2017/18 UNAIDS Spectrum was used. We systematically integrated data from the different sources to explore PMTCT programme performance at each step of the cascade. We also conducted spatial analysis to identify hotspots of MTCT., Results: We developed cascades for HIV-positive and negative-mothers, and HIV exposed and infected infants to 24 months post-partum. Most data were available on HIV positive mothers. Few data were available 6-8 weeks post-delivery for HIV exposed/infected infants and none were available post-delivery for HIV-negative mothers. The different data sources largely concurred. Antenatal care (ANC) registration was high, although women often presented late. There was variable implementation of PMTCT services, MTCT hotspots were identified. Factors positively associated with MTCT included delayed ANC registration and mobility (use of more than one health facility) during pregnancy/breastfeeding. There was reduced MTCT among women whose partners accompanied them to ANC, and infants receiving antiretroviral prophylaxis. Notably, the largest contribution to MTCT was from postnatal women who had previously tested negative (12/25 in survey data, 17.6% estimated by Spectrum modelling). Data integration enabled formulation of interventions to improve programmes., Conclusions: Data integration was feasible and identified gaps in programme implementation/documentation leading to corrective interventions. Incident infections among mothers are the largest contributors to MTCT: there is need to strengthen the prevention cascade among HIV-negative women., (© 2020 The Authors.

Background: Despite a growing body of literature on HIV service costs in sub-Saharan Africa, only a few studies have estimated the facility-level cost of prevention of Mother-to-Child Transmission (PMTCT) services, and even fewer provide insights into the variation of PMTCT costs across facilities. In this study, we present the first empirical costs estimation of the accelerated program for the prevention of mother-to-child transmission of HIV in Zimbabwe and investigate the determinants of heterogeneity of the facility-level average cost per service. To understand such variation, we explored the association between average costs per service and supply-and demand-side characteristics, and quality of services. One aspect of the supply-side we explore carefully is the scale of production-which we define as the annual number of women tested or the yearly number of HIV-positive women on prophylaxis., Methods: We collected rich data on the costs and PMTCT services provided by 157 health facilities out of 699 catchment areas in five provinces in Zimbabwe for 2013. In each health facility, we measured total costs and the number of women covered with PMTCT services and estimated the average cost per woman tested and the average cost per woman on either ARV prophylaxis or ART. We refer to these facility-level average costs per service as unitary costs. We also collected information on potential determinants of the variation of unitary costs. On the supply-side, we gathered data on the scale of production, staff composition and on the types of antenatal and family planning services provided. On the demand side, we measured the total population at the catchment area and surveyed eligible pairs of mothers and infants about previous use of HIV testing and prenatal care, and on the HIV status of both mothers and infants. We explored the determinants of unitary cost variation using a two-stage linear regression strategy., Results: The average annual total cost of the PMTCT program per facility was US$16,821 (median US$8,920). The average cost per pregnant woman tested was US$80 (median US$47), and the average cost per HIV-positive pregnant woman initiated on ARV prophylaxis or treatment was US$786 annually (median US$420). We found substantial heterogeneity of unitary costs across facilities regardless of facility type. The scale of production was a strong predictor of unitary costs variation across facilities, with a negative and statistically significant correlation between the two variables (p<0.01)., Conclusions: These findings are the first empirical estimations of PMTCT costs in Zimbabwe. Unitary costs were found to be heterogeneous across health facilities, with evidence consistent with economies of scale., Competing Interests: The authors have declared that no competing interests exist.

Objectives: Diarrhoeal illness is a leading cause of childhood morbidity and mortality and has long-term negative impacts on child development. Although flooring, water and sanitation have been identified as important routes of transmission of diarrhoeal pathogens, research examining variability in the association between flooring and diarrhoeal illness by water and sanitation is limited., Methods: We utilised cross-sectional data collected for the evaluation of Zimbabwe's Prevention of Mother-to-Child HIV transmission programme in 2014 and 2017-18. Mothers of infants 9-18 months of age self-reported the household's source of drinking water and type of sanitation facility, as well as infant diarrhoeal illness in the four weeks prior to the survey. Household flooring was assessed using interviewer observation, and households in which the main material of flooring was dirt/earthen were classified as having unimproved flooring, and those with solid flooring (e.g. cement) were classified as having improved flooring., Results: Mothers of infants living in households with improved flooring were less likely to report diarrhoeal illness in the last four weeks (PD a  = -4.8%, 95% CI: -8.6, -1.0). The association between flooring and diarrhoeal illness did not vary by the presence of improved/unimproved water (p RERI  = 0.91) or sanitation (p RERI  = 0.76)., Conclusions: Our findings support the hypothesis that household flooring is an important pathway for the transmission of diarrhoeal pathogens, even in settings where other aspects of sanitation are sub-optimal. Improvements to household flooring do not require behaviour change and may be an effective and expeditious strategy for reducing childhood diarrhoeal illness irrespective of household access to improved water and sanitation., (© 2020 John Wiley & Sons Ltd.)

Background: Heavy load carrying has been associated with musculoskeletal discomfort (MSD) and disability. However, there is a lack of research investigating this association in resource-constrained settings where heavy load carrying by women is common., Objectives: We assessed the impact of heavy load carrying on musculoskeletal pain and disability among women in Shinyanga Region, Tanzania, in an exploratory cross-sectional study., Methods: Eligible participants were a convenience sample of women, at least 18 years of age, who passed a study recruitment site carrying a load. We collected information on load-carrying practices, including frequency and time spent carrying water, wood, agricultural products, coal, sand, or rocks, and measured the weight of the load carried at the time. Outcomes included self-reported MSDs, defined as experiencing pain lasting >3 days in the neck, head, back, knees, feet and/or ankles within the last 1 year, and related disability. Using multivariable logistic regression we assessed for associations between load carrying exposures and MSDs and disability., Findings: Results showed a high prevalence of MSDs across the body regions assessed and evidence to suggest a relationship of back pain and related disability with several measures of load-carrying, including duration, frequency, and weight. Multivariable analyses revealed associations of increased load carrying exposures with low back pain (LBP) and related disability, including statistically significant increases in odds of LBP with increasing weight, total duration of load carrying/week and cumulative loads/week., Conclusions: Findings indicate a substantial burden of MSDs and disability in this population of women who carry heavy loads daily. The extent of discomfort and disability increased with increasing exposure to various load-carrying measures, especially for LBP. Larger epidemiologic studies that definitively assess relationships of load carrying with MSDs and disability are warranted., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2020 The Author(s).)

Background: Ambitious targets have been set to end the HIV epidemic by 2030. Such targets assume that tools to end HIV exist and are successfully being deployed across populations, albeit unequally. Implementation science approaches are needed to understand the drivers of disparities and how to bring effective interventions to those most in need. We describe a hybrid implementation science approach, adapting a strategy to facilitate retention and viral suppression (VS) among people living with HIV/AIDS in Tanzania., Methods/design: We used Proctor framework and the multiphase optimization strategy to optimize a cash transfer to improve antiretroviral therapy adherence and VS among people living with HIV/AIDS in Tanzania. This involved 3 trials. The first trial tested the efficacy of cash and food assistance compared with the standard of care in improving antiretroviral therapy adherence among treatment initiators. Cash transfers were superior to the standard of care and noninferior, less expensive, and logistically simpler to implement compared with food. The second trial is dose-finding: identifying the optimal amount of cash for a 20% improvement in VS at 6 months. Before this, components were simplified to maximize reach, align with local policies, and reduce staff time. We assessed implementation science constructs to understand barriers to uptake and sustainability. Trial 3 is a cluster randomized controlled trial, testing the effectiveness of the optimized intervention in multiple settings., Discussion/implications: Our process illustrates the utility of applying multiple implementation science frameworks to arrive at an optimal implementation strategy to bridge the know-do gap with data to show efficacy and maximum potential for scalability and sustainability.

Objective: At 789 maternal deaths per 100,000 live births, South Sudan has one of the worst maternal mortality indicators in the world. Utilization of maternal health services namely antenatal care (ANC), skilled birth attendance (SBA), and early postnatal care (EPNC) is critical in reducing these deaths. We evaluated whether health education on birth preparedness and complication readiness (BPCR) has an impact on the utilization of skilled birth attendance and early postnatal care in Mundri East County, South Sudan., Design: We used observational data collected from antenatal clinics in South Sudan to perform a propensity score matched analysis. Treatment effects in both unmatched and matched cohorts were estimated using modified Poisson regression analysis with robust standard errors in prevalence risk ratios (PR) and 95% confidence intervals., Setting: 13 primary healthcare facilities., Participants: 385 postpartum mothers., Interventions: Health education on BPCR., Measurements: Two outcomes were evaluated: (1) SBA measured as delivery in a health facility, and (2) EPNC use measured as use of postnatal care within 2-7 days of delivery., Findings: Data on 243 (67.9%) mothers who attended antenatal care were analyzed. 92 participants who received BPCR health education were matched with 92 who had never. In unmatched adjusted analysis, health education on BPCR significantly increased SBA (Adjusted PR (APR), 1.99; 95% confidence interval (CI), 1.99-3.65) but not EPNC use (APR, 1.78; 95% CI, 0.73-4.35). In propensity score-matched analysis, SBA significantly improved (PR, 2.64; 95% CI, 1.91-3.66) while the increase in EPNC use was insignificant (PR, 1.14; 95% CI, 0.43-3.03)., Conclusions: Health education on BPCR improves SBA but not EPNC use among mothers in Mundri East County, South Sudan., Implication for Practice: South Sudan's health systems should design new strategies to enhance EPNC use in order to significantly reduce maternal and newborn deaths in the earlier days of the postpartum period. In addition, a qualitative study is needed to identify barriers to EPNC use., (Copyright © 2019. Published by Elsevier Ltd.)

Evidence of the effectiveness of programs to change gendered social norms related to intimate partner violence (IPV) is growing, but their potential to significantly impact actual occurrence of IPV at population level is lacking. We study whether modest changes in gendered social norms related to wife-beating can result in significant changes in the incidence of emotional, physical, and sexual IPV among ever married women in Uganda. We employ an imputation-based causal inference approach, based on nationally representative Demographic Health Survey data. The steps are (1) model the association between adjusted neighborhood norms and experiences of IPV using a random effects logistic regression model, (2) impute unobserved counterfactual probabilities of experiencing IPV for each woman while manipulating her neighborhood norms by setting it to different values, (3) average the probabilities across the population, and (4) bootstrap confidence intervals. Results show that statistically significant inverse associations between more prohibitive neighborhood IPV norms and women's experiences of different forms of IPV at the population level exist. The effect is however small, that even if an entire community disapproves of wife-beating, incidence of IPV falls by about 10 percentage points to 48.5% (95% CI 46.0%-50.9%) from the observed value of 57.6% (95% CI 55.2%-59.9%). Furthermore, changes in neighborhood social norms are found to have no statistical significant effect on the incidence of sexual violence. In conclusion, changing gendered social norms related to wife-beating will not result in significant reductions in different forms for IPV at the population level.

Purpose of the Review: In 2015, antiretroviral therapy (ART) was recommended for all people living with HIV (PLHIV) regardless of CD4 count ("Treat All"). To better understand how to improve linkage to care under these new guidelines, we conducted a systematic review of studies evaluating linkage interventions in Sub-Saharan Africa under Treat All., Recent Findings: We identified 14 eligible articles and qualitatively analyzed the effectiveness of the interventions. Increases in linkage were reported by supply-side and counseling interventions. Mobile testing and economic incentives did not increase linkage. Given the lag time between adoption and implementation, only two of the studies were conducted in a Treat All setting. None of the interventions specifically focused on re-linking PLHIV who had disengaged from care. Future studies must design interventions that target not only newly diagnosed or treatment naïve PLHIV, but should explicitly focus on PLHIV who have disengaged from care.

Objective: Food insecurity impedes antiretroviral therapy (ART) adherence. We previously demonstrated that short-term cash and food incentives increased ART possession and retention in HIV services in Tanzania. To elucidate potential pathways that led to these achievements, we examined whether incentives also improved food insecurity., Design: Three-arm randomized controlled trial., Methods: From 2013 to 2015, 805 food-insecure adult ART initiates (≤90 days) at three clinics were randomized to receive cash or food transfers (∼$11 per month for ≤6 months, conditional on visit attendance) or standard-of-care (SOC) services. We assessed changes from baseline to 6 and 12 months in: food insecurity (severe; access; dietary diversity), nutritional status (body weight; BMI), and work status. Difference-in-differences average treatment effects were estimated using inverse-probability-of-censoring-weighted longitudinal regression models., Results: The modified intention-to-treat analysis included 777 nonpregnant participants with 41.6% severe food insecurity. All three study groups experienced improvements from baseline in food insecurity, nutritional status, and work status. After 6 months, severe food insecurity declined within the cash (-31.4% points to 11.5%) and food (-30.3 to 10.4%) groups, but not within the SOC. Relative to the SOC, severe food insecurity decreased by an additional 24.3% points for cash (95% CI -45.0 to -3.5) and 23.3% percent points for food (95% CI -43.8 to -2.7). Neither intervention augmented improvements in severe food insecurity at 12 months, nor food access, dietary diversity, nutritional status, or work status at 6 or 12 months., Conclusion: Small cash and food transfers provided at treatment initiation may mitigate severe food insecurity. These effects may have facilitated previously observed improvements in ART adherence.

Background: WHO recommends that HIV infected women receive antiretroviral therapy (ART) minimally during pregnancy and breastfeeding ("Option B"), or ideally throughout their lives regardless of clinical stage ("Option B+") (Coovadia et al., Lancet 379:221-228, 2012). Although these recommendations were based on clinical trials demonstrating the efficacy of ART during pregnancy and breastfeeding, the population-level effectiveness of Option B+ is unknown, as are retention on ART beyond the immediate post-partum period, and the relative impact and cost-effectiveness of Option B+ compared to Option A (Centers for Disease Control and Prevention, Morb Mortal Wkly Rep 62:148-151, 2013; Ahmed et al., Curr Opin HIV AIDS 8:473-488, 2013). To address these issues, we conducted an impact evaluation of Zimbabwe's prevention of mother to child transmission programme conducted between 2011 and 2018 using serial, community-based cross-sectional serosurveys, which spanned changes in WHO recommendations. Here we describe the rationale for the design and analysis., Methods/design: Our method is to survey mother-infant pairs residing in the catchment areas of 157 health facilities randomly selected from 5 of 10 provinces in Zimbabwe. We collect questionnaires, blood samples from mothers and babies for HIV antibody and viral load testing, and verbal autopsies for deceased mothers/babies. Using this approach, we collected data from two previous time points: 2012 (pre-Option A standard of care), 2014 (post-Option A / pre-Option B+) and will collect a third round of data in 2017-18 (post Option B+ implementation) to monitor population-level trends in mother-to-child transmission of HIV (MTCT) and HIV-free infant survival. In addition, we will collect detailed information on facility level factors that may influence service delivery and costs., Discussion: Although the efficacy of antiretroviral therapy (ART) during pregnancy and breastfeeding for prevention of mother-to-child transmission of HIV (PMTCT) has been well-documented in randomized trials, little evidence exists on the population-level impact and cost-effectiveness of Option B+ or the influence of the facility on implementation (Siegfried et al., Cochrane Libr 7:CD003510, 2017). This study will provide essential data on these gaps and will provide estimates on retention in care among Option B+ clients after the breastfeeding period., Trial Registration: NCT03388398 Retrospectively registered January 3, 2018.

Background: The postpartum period is an opportune time for contraception adoption, as women have extended interaction with the reproductive healthcare system and therefore more opportunity to learn about and adopt contraceptive methods. This may be especially true for women who experience unintended pregnancy, a key target population for contraceptive programs and programs to eliminate mother-to-child HIV transmission. Among women in Zimbabwe surveyed in 2014, we examined the relationship between pregnancy intention associated with a woman's most recent pregnancy, and her subsequent postpartum contraceptive use., Methods: In our analysis we utilized a dataset from a random selection of catchment areas in Zimbabwe to examine the association between pregnancy intention of most recent pregnancy and subsequent postpartum contraceptive use using multinomial logistic regression models. We also explored whether this association differed by women's HIV status. Finally, we examined the association between pregnancy intention and changes in contraception from the pre- to postpartum periods., Results: Findings suggest that women who reported that their pregnancy was unintended adopted less modern (all non-traditional) contraceptive methods overall, but adopted long-acting reversible contraception (LARC) more frequently than women reporting an intended pregnancy (OR 1.41; CI 1.18, 1.68). Among HIV-positive women, this relationship was particularly strong (OR 3.12; CI 1.96, 4.97). However, when examining changes in contraceptive use from the pre-pregnancy to the postpartum period, women who had an unintended pregnancy had lower odds of changing to a more effective method postpartum overall (OR 0.71; CI 0.64, 0.79)., Conclusions: We did not find evidence of higher modern method adoption in the postpartum period among women with an unintended pregnancy. However, women who were already on a method in the pre-pregnancy period were catalyzed to move to more effective methods (such as LARC) postpartum. This study provides evidence of low modern (non-traditional) method adoption in general in the postpartum period among a vulnerable sub-population in Zimbabwe (women who experience unintended pregnancy). Simultaneously, however, it shows a relatively greater portion specifically of LARC use among women with an unintended pregnancy. Further research is needed to more closely examine the motivations behind these contraceptive decisions in order to better inform distribution and counseling programs.

Background: In the United States, young men who have sex with men (YMSM) experience a disproportionate burden of HIV and sexually transmitted infections (STIs). Mobile health (mHealth) interventions, including those that incorporate elements of games ("gamification"), have the potential to improve YMSM engagement in desirable sexual health services and behaviors. Gamification leverages theory and tools from behavioral science to motivate people to engage in a behavior in a context of fun. The objective of the study was to determine whether an intervention using gamification is acceptable to YMSM in California and potentially increases repeat HIV screening., Methods: Eligible YMSM were: (I) 18-26 years, (II) born as and/or self-identified as male, (III) reported male sexual partners, and (IV) lived in a zip code adjacent to one of the two study clinics in Oakland and Hollywood, California. The gamification intervention, Stick To It , had four components: (I) recruitment (clinic-based and online), (II) online enrollment, (III) online activities, and (IV) 'real-world' activities at the clinic. Participants earned points through online activities that could be redeemed for a chance to win prizes during HIV/STI screening and care visits. The primary outcome was intervention acceptability measured with participant engagement data and in-depth interviews. The secondary outcome was the intervention's preliminary effectiveness on repeat HIV screening within 6 months, restricted to the subset of men who provided consent for review of medical records and who had ≥6 months of follow-up. Outcomes were compared to a historical control group of similar YMSM who attended study clinics in the 12 months prior to intervention implementation., Results: Overall, 166 of 313 (53%) eligible YMSM registered. After registration, 93 (56%) participants completed enrollment and 31 (19%) completed ≥1 online activity in the subsequent 6 months. Points were redeemed in clinic by 11% of the 166 users (27% and 5% of those who enrolled in the clinic and online, respectively). Despite moderate engagement, participants provided a positive assessment of the program in interviews, reporting that the inclusion of game elements was motivating. The analysis of repeat HIV testing was assessed among 31 YMSM who consented to medical record review and who had ≥6 months of follow-up. During follow-up, 15 (48%) received ≥2 HIV tests compared to 157 (30%) of a historical comparison group of 517 similar YMSM who lived in the same zip codes and who received care at the same clinics before the intervention (OR =2.15, 95% CI: 1.03-4.47, P=0.04)., Conclusions: Engagement in the intervention was modest, with YMSM who enrolled in a clinic more actively engaged than YMSM who enrolled online. Among the subset of participants recruited in the clinic, repeat HIV screening was higher than a comparison group of similar YMSM attending the same clinic in the prior year., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Background: Cash and in-kind incentives can improve health outcomes in various settings; however, there is concern that incentives may 'crowd out' intrinsic motivation to engage in beneficial behaviors. We examined this hypothesis in a randomized trial of food and cash incentives for people living with HIV infection in Tanzania., Methods: We analyzed data from 469 individuals randomized to one of three study arms: standard of care, short-term cash transfers, or short-term food assistance. Eligible participants were: 1) ≥18 years old; 2) HIV-infected; 3) food insecure; and 4) initiated antiretroviral therapy (ART) ≤90 days before the study. Food or cash transfers, valued at ~$11 per month and conditional on attending clinic visits, were provided for ≤6 months. Intrinsic motivation was measured at baseline, 6, and 12 months using the autonomous motivation section of the Treatment Self-Regulation Questionnaire (TSRQ). We compared the change in TSRQ score from baseline to 6 and 12 months and the change within study arms., Results: The mean intrinsic motivation score was 2.79 at baseline (range: 1-3), 2.91 at 6 months (range: 1-3), and 2.95 at 12 months (range: 2-3), which was 6 months after the incentives had ended. Among all patients, the intrinsic motivation score increased by 0.13 points at 6 months (95% CI (0.09, 0.17), Cohen's d = 0.29) and 0.19 points at 12 months (95% CI (0.14, 0.24), Cohen's d = 0.49). Intrinsic motivation also increased within each study group at 6 months: 0.15 points in the food arm (95% CI (0.09, 0.21), Cohen's d = 0.37), 0.11 points in the cash arm (95% CI (0.05, 0.18), Cohen's d = 0.25), and 0.08 points in the comparison arm (95% CI (-0.03, 0.19), Cohen's d = 0.21); findings were similar at 12 months. Increases in motivation were statistically similar between arms at 6 and 12 months., Conclusion: Intrinsic motivation for ART adherence increased significantly both overall and within the food and cash incentive arms, even after the incentive period was over. Increases in motivation did not differ by study group. These results suggest that incentive interventions for treatment adherence should not be withheld due to concerns of crowding out intrinsic motivation., Competing Interests: The authors have declared that no competing interests exist.

This study tests whether women's relationship power modifies the effect of a conditional cash transfer (CCT) on STI risk. We analyzed 988 women enrolled in the RESPECT study in Tanzania, a yearlong, randomized-controlled trial testing the effectiveness of a CCT to reduce STI incidence. Women were randomized at the individual level to a no-cash control group, a low-cash, or a high-cash study arm. After one year, there was no main effect of study arm on risk of having an STI among women. However, in tests of heterogeneity, the effect of the CCT varied by a woman's relationship power (adjusted RRs of the interaction term for women with higher relationship power: RR 0.567 (95% CI 0.240-0.895) for high cash and RR 1.217 (95% CI 0.794-1.641) for low cash). Specifically, women with higher relationship power in the low cash transfer arm had an elevated risk of testing positive for an STI, whereas women with high relationship power in the high cash transfer arm had a decreased risk of testing positive for an STI.

A recently concluded randomized study in Tanzania found that short-term conditional cash and food transfers significantly improved HIV-infected patients’ possession of antiretroviral therapy (ART) and reduced patient loss to follow-up (LTFU) (McCoy, S. I., Njau, P. F., Fahey, C., Kapologwe, N., Kadiyala, S., Jewell, N. P., & Padian, N. S. (2017). Cash vs. food assistance to improve adherence to antiretroviral therapy among HIV-infected adults in Tanzania. AIDS, 31(6), 815–825. doi:10.1097/QAD.0000000000001406 ). We examined whether these transfers had differential effects within population subgroups. In the parent study, 805 individuals were randomized to one of three study arms: standard-of-care (SOC) HIV services, food assistance, or cash transfer. We compared achievement of the medication possession ratio (MPR) ≥ 95% at 6 and 12 months and patient LTFU at 12 months between those receiving the SOC and those receiving food or cash (combined). Using a threshold value of p < 0.20 to signal potential effect measure modifiers (EMM), we compared intervention effects, expressed as risk differences (RD), within subgroups characterized by: sex, age, wealth, and time elapsed between HIV diagnosis and ART initiation. Short-term transfers improved 6 and 12-month MPR ≥ 95% and reduced 12-month LTFU in most subgroups. Study results revealed wealth and time elapsed between HIV diagnosis and ART initiation as potential EMMs, with greater effects for 6-month MPR ≥ 95% in the poorest patients (RD: 32, 95% CI: (9, 55)) compared to those wealthier (RD: 16, 95% CI: (5, 27); p = 0.18) and in newly diagnosed individuals (<90 days elapsed since diagnosis) (RD: 25, 95% CI: (13, 36)) compared to those with ≥90 days (RD: 0.3, 95% CI (−17, 18); p = 0.02), patterns which were sustained at 12 months. Results suggest that food and cash transfers may have stronger beneficial effects on ART adherence in the poorest patients. We also provide preliminary data suggesting that targeting interventions at patients more recently diagnosed with HIV may be worthwhile. Larger and longer-term assessments of transfer programs for the improvement of ART adherence and their potential heterogeneity by sub-population are warranted.

Background: Hepatitis C virus (HCV) infection is highly prevalent among prisoners and this prevalence estimates reach 64% among prisoners who inject illicit drugs. Prisons are important sites for HCV transmission in the absence of access to sterile injecting equipment; hence, it can be transmitted between prisoners who share contaminated needles and syringes. We aimed to estimate the prevalence of risk factors for anti-HCV prevalence, with particular interest on injecting behavior, and to assess correlates of anti-HCV positivity among Mexico City prisoners., Methods: Cross-sectional study based on information -collected in three male and two female prisons in Mexico City during 2010-2011- about sexually transmitted infections, socio-demographics, criminal history, substance use, vitamin injection, tattooing, among others (n=3,910). Weighted multivariable adjusted logistic regression models were estimated to assess the overall and differential odds for anti-HCV due to injecting behavior., Results: Overall prevalence of anti-HCV was 3.3%. This figure rose to 43.1% among prisoners with a history of illicit drug injection. Prisoners with history of vitamin injection showed a similar prevalence of anti-HCV (43.8%). After stratifying by substance injected, the adjusted odds ratio was 9.8 (95% CI: 4.0, 23.8) for illicit drug injection and 11.9 (95% CI: 5.8, 23.8) for illicit drug and vitamin injection., Conclusion: Based on data from the most populous prisons in Mexico City, this study showed that anti-HCV is highly prevalent among prisoners with history of injecting behavior. In this sense, injecting behavior per-se, independent of the substance used, is associated with increased odds of anti-HCV positivity., (Copyright © 2017 Elsevier B.V. All rights reserved.)

Background: Couples' HIV testing and counselling (CHTC) is associated with greater engagement with HIV prevention and care than individual testing and is cost-effective, but uptake remains suboptimal. Initiating discussion of CHTC might result in distrust between partners. Offering incentives for CHTC could change the focus of the pre-test discussion. We aimed to determine the impact of incentives for CHTC on uptake of couples testing and HIV case diagnosis in rural Zimbabwe., Methods: In this cluster-randomised trial, 68 rural communities (the clusters) in four districts receiving mobile HIV testing services were randomly assigned (1:1) to incentives for CHTC or not. Allocation was not masked to participants and researchers. Randomisation was stratified by district and proximity to a health facility. Within each stratum random permutation was done to allocate clusters to the study groups. In intervention communities, residents were informed that couples who tested together could select one of three grocery items worth US$1·50. Standard mobilisation for testing was done in comparison communities. The primary outcome was the proportion of individuals testing with a partner. Analysis was by intention to treat. 3 months after CHTC, couple-testers from four communities per group individually completed a telephone survey to evaluate any social harms resulting from incentives or CHTC. The effect of incentives on CHTC was estimated using logistic regression with random effects adjusting for clustering. The trial was registered with the Pan African Clinical Trial Registry, number PACTR201606001630356., Findings: From May 26, 2015, to Jan 29, 2016, of 24 679 participants counselled with data recorded, 14 099 (57·1%) were in the intervention group and 10 580 (42·9%) in the comparison group. 7852 (55·7%) testers in the intervention group versus 1062 (10·0%) in the comparison group tested with a partner (adjusted odds ratio 13·5 [95% CI 10·5-17·4]). Among 427 (83·7%) of 510 eligible participants who completed the telephone survey, 11 (2·6%) reported that they were pressured or themselves pressured their partner to test together; none regretted couples' testing. Relationship unrest was reported by eight individuals (1·9%), although none attributed this to incentives., Interpretation: Small non-monetary incentives, which are potentially scalable, were associated with significantly increased CHTC and HIV case diagnosis. Incentives did not increase social harms beyond the few typically encountered with CHTC without incentives. The intervention could help achieve UNAIDS 90-90-90 targets., Funding: The study was funded by the UK Department for International Development, Irish AID, and Swedish SIDA, through Population Services International Zimbabwe under the Integrated Support Program., (Copyright © 2017 The Author(s).

Introduction: Community health workers (CHWs) are lay workers who have the potential to enhance services to prevent mother-to-child HIV transmission (PMTCT) and improve the health of women living with HIV infection. We conducted a cluster-randomized trial of an intervention to integrate CHWs with 'Option B+' PMTCT services in Shinyanga Region, Tanzania., Methods: The intervention was implemented for 11 months and included four integrated components: 1) formal linkage of CHWs to health facilities; 2) CHW-led antiretroviral therapy (ART) adherence counseling; 3) loss to follow-up tracing by CHWs; and 4) distribution of Action Birth Cards (ABCs), a birth planning tool. We cluster-randomized 32 facilities offering PMTCT services, within strata of size, to the intervention (n = 15) or comparison (standard of care, n = 17) groups. Intervention effectiveness was determined with a difference-in-differences strategy based on clinical and pharmacy data from HIV-infected postpartum women at baseline (births in 2014) and endline (births April-Oct 2015). The primary outcome was retention in care between 60 and 120 days postpartum. Secondary outcomes included ART initiation, timing of ART initiation (as measured by week of gestation), and ART adherence 90 days postpartum, measured using the medication possession ratio (MPR≥95%)., Results: Intervention and comparison facilities were similar at baseline. Data were collected from 1,152 and 678 mother-infant pairs at baseline and endline, respectively. There were no significant differences in retention in care, ART initiation, or timing of ART initiation between the intervention and control groups. Adherence (MPR≥95%) at 90 days postpartum was 11.3 percentage points higher in the intervention group in ITT analyses (95% CI: -0.7, 23.3, p = 0.06), though this effect was attenuated after adjusting for baseline imbalance (9.5 percentage points, 95% CI: -2.9, 22.0, p = 0.13). Among only sites that had the greatest fidelity to the intervention, however, we found a stronger effect on adherence (13.6 percentage points, 95% CI: 2.5, 24.6)., Conclusions: Despite being feasible and acceptable, the CHW-based intervention did not have strong effects on most PMTCT indicators. CHW involvement in PMTCT programs may improve ART adherence among HIV-infected postpartum women, however, and success appears heavily dependent on program implementation., Trial Registration: Registry for International Development Impact Evaluations (RIDIE, ID 552553838b402) and ClinicalTrials.gov (NCT03058484).

Background: In the United States, young men who have sex with men (YMSM) remain disproportionately affected by human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs). Although routine HIV/STI screening is pivotal to the timely diagnosis of HIV and STIs, initiation of appropriate treatment, and reduced onward disease transmission, repeat screening is underused. Novel interventions that incorporate elements of games, an approach known as gamification, have the potential to increase routinization of HIV/STI screening among YMSM., Objective: The study aims to test the hypothesis that an incentive-based intervention that incorporates elements of gamification can increase routine HIV/STI screening among YMSM in California., Methods: The study consists of a formative research phase to develop the intervention and an implementation phase where the intervention is piloted in a controlled research setting. In the formative research phase, we use an iterative development process to design the intervention, including gathering information about the feasibility, acceptability, and expected effectiveness of potential game elements (eg, points, leaderboards, rewards). These activities include staff interviews, focus group discussions with members of the target population, and team meetings to strategize and develop the intervention. The final intervention is called Stick To It and consists of 3 components: (1) online enrollment, (2) Web-based activities consisting primarily of quizzes and a countdown "timer" to facilitate screening reminders, and (3) in-person activities that occur at 2 sexual health clinics. Participants earn points through the Web-based activities that are then redeemed for chances to win various prizes during clinic visits. The pilot study is a quasi-experimental study with a minimum of 60 intervention group participants recruited at the clinics, at community-based events, and online. We will compare outcomes in the intervention group with a historical control group consisting of individuals meeting the inclusion criteria who attended study clinics in the 12 months prior to intervention implementation. Eligible participants in the pilot study (1) are 18 to 26 years old, (2) were born or identify as male, 3) report male sexual partners, and 4) have a zip code of residence within defined areas in the vicinity of 1 of the 2 implementation sites. The primary outcome is repeat HIV/STI screening within 6 months., Results: This is an ongoing research study with initial results expected in the fourth quarter of 2017., Conclusions: We will develop and pilot test a gamification intervention to encourage YMSM to be regularly screened for HIV/STIs. The results from this research will provide preliminary evidence about the potential effectiveness of using gamification to amplify health-related behavioral change interventions. Further, the research aims to determine the processes that are essential to developing and implementing future health-related gamification interventions., Trial Registration: Clinicaltrials.gov NCT02946164; https://clinicaltrials.gov/ct2/show/NCT02946164 (Archived by WebCite at http://www.webcitation.org/6ri3G4HwD)., (©Christopher M Mejia, Daniel Acland, Raluca Buzdugan, Reva Grimball, Lauren Natoli, Mark R McGrath, Jeffrey D Klausner, Sandra I McCoy.

Financial and in-kind incentives have been shown to improve outcomes along the HIV care cascade, however the potential mechanismsthrough which they work remain unclear. To identify the pathways through which incentives improve retention in care and adherence to antiretroviral therapy (ART), we conducted a qualitative study with participants in a trial evaluating conditional food and cash incentives for HIV-positive food insecure adults in Shinyanga, Tanzania. We found that the incentives acted through three pathways to potentially increase retention in care and adherence to ART: (1) addressing competing needs and offsetting opportunity costs associated with clinic attendance, (2) alleviating stress associated with attending clinic and meeting basic needs, and (3) by potentially increasing motivation. Participants did not report any harmful events associated with the incentives, but reported myriad beneficial effects on household welfare. Understanding how incentives are used and how they impact outcomes can improve the design of future interventions.

Background: Interventions incorporating constructs from behavioral economics and psychology have the potential to enhance HIV 'treatment as prevention' (TasP) strategies. To test this hypothesis, we evaluated an intervention to improve antiretroviral therapy (ART) adherence based on the concepts of social norms and priming., Methods: We used tools from marketing research and patient-centered design to develop a combination intervention that included visual feedback about clinic-level retention in care, a self-relevant prime, and useful take-home items with the priming image. The intervention was implemented at two HIV primary clinics in Shinyanga, Tanzania in 2-week intervals for six months. We conducted a quasi-experimental pilot study with a random sample of exposed and unexposed adult patients living with HIV infection (PLHIV) to compare retention and the proportion of patients with medication possession ratio (MPR) ≥95% after six months. Intervention acceptability was determined with a convenience sample of 405 PLHIV at baseline (n = 189) and endline (n = 216)., Results: Medical records were reviewed for 438 PLHIV (320 intervention, 118 standard of care). In adjusted analyses, PLHIV exposed to the intervention were significantly more likely to be in care after 6 months (87% vs. 79%, adjusted odds ratio (ORa) = 1.73, 95% CI: 1.08, 2.78, p<0.05) and were more likely to achieve MPR≥95% (70% vs. 59%, OR = 1.51, 95% CI: 0.96, 2.37, p = 0.07). The intervention was associated with increases in staff support of treatment goals (100% vs. 95%, p = 0.01) and life goals (66% vs. 50%, p<0.01), the perceived likelihood of other patients' adherence (54% vs. 32%, p<0.01), support from other patients (71% vs. 60%, p = 0.03), and being very satisfied with care (53% vs. 35%, p<0.01)., Conclusions: This novel intervention has the potential to improve the clinic experience, short-term retention in care, and ART adherence. Future studies are needed to expand the generalizability of the approach and evaluate effectiveness on clinical outcomes., Trial Registration: Clinicaltrials.gov NCT02938533.

Female Sex Workers are a core population in the HIV epidemic, and interventions such as conditional cash transfers (CCTs), effective in other health domains, are a promising new approach to reduce the spread of HIV. Here we investigate how a population of Tanzanian female sex workers, though constrained in many ways, experience and use their power in the context of a CCT intervention that incentivizes safe sex. We analyzed 20 qualitative in-depth interviews with female sex workers enrolled in a randomized-controlled CCT program, the RESPECT II pilot, and found that while such women have limited choices, they do have substantial power over their work logistics that they leveraged to meet the conditions of the CCT and receive the cash award. It was through these decisions over work logistics, such as reducing the number of workdays and clients, that the CCT intervention had its greatest impact on modifying female sex workers' behavior., (Copyright © 2017.

Objective: We evaluated the effectiveness of short-term cash and food assistance to improve adherence to antiretroviral therapy (ART) and retention in care among people living with HIV in Tanzania., Methods: At three clinics, 805 participants were randomized to three groups in a 3 : 3 : 1 ratio, stratified by site : nutrition assessment and counseling (NAC) and cash transfers (∼$11/month, n = 347), NAC and food baskets (n = 345), and NAC-only (comparison group, n = 113, clinicaltrials.gov NCT01957917). Eligible people living with HIV were at least 18 years, initiated ART 90 days or less prior, and food insecure. Cash or food was provided for 6 or less consecutive months, conditional on visit attendance. The primary outcome was medication possession ratio (MPR ≥ 95%) at 6 months. Secondary outcomes were appointment attendance and loss to follow-up (LTFU) at 6 and 12 months., Results: The primary intent-to-treat analysis included 800 participants. Achievement of MPR ≥ 95% at 6 months was higher in the NAC + cash group compared with NAC-only (85.0 vs. 63.4%), a 21.6 percentage point difference [95% confidence interval (CI): 9.8, 33.4, P < 0.01]. MPR ≥ 95% was also significantly higher in the NAC + food group vs. NAC-only (difference = 15.8, 95% CI: 3.8, 27.9, P < 0.01). When directly compared, MPR ≥ 95% was similar in the NAC + cash and NAC + food groups (difference = 5.7, 95% CI: -1.2, 12.7, P = 0.15). Compared with NAC-only, appointment attendance and LTFU were significantly higher in both the NAC + cash and NAC + food groups at 6 months. At 12 months, the effect of NAC + cash, but not NAC + food, on MPR ≥ 95% and retention was sustained., Conclusion: Short-term conditional cash and food assistance improves ART possession and appointment attendance and reduces LTFU among food-insecure ART initiates in Tanzania.

Background: We assessed Zimbabwe's progress toward elimination of mother-to-child HIV transmission (MTCT) under Option A., Methods: We analyzed 2012 and 2014 cross-sectional serosurvey data from mother-infant pairs residing in the same 157 health facility catchment areas randomly sampled from five provinces. Eligible women were at least 16 years and mothers/caregivers of infants born 9-18 months prior. We aggregated individual-level questionnaire and HIV serostatus within catchment areas or district to estimate MTCT and the number of HIV-infected infants; these data were mapped using facility global positioning system coordinates., Results: A weighted population of 8800 and 10 404 mother-infant pairs was included from 2012 and 2014, respectively. In 2014, MTCT among HIV-exposed infants was 6.7% (95% confidence interval: 5.2, 8.6), not significantly different from 2012 (8.8%, 95% confidence interval: 6.9, 11.1, P = 0.13). From 2012 to 2014, self-reported antiretroviral therapy or prophylaxis among HIV-infected women increased from 59 to 65% (P = 0.05), as did self-reported infant antiretroviral prophylaxis (63 vs. 67%, P = 0.08). In 2014, 65 (41%), 55 (35%), and 37 (24%) catchment areas had the same, lower, and higher MTCT rate as in 2012, respectively. MTCT in 2014 varied by catchment areas (median = 0%, mean = 4.9%, interquartile range = 0-10%) as did the estimated number of HIV-infected infants (median = 0, mean = 1.1, interquartile range = 0-1.0). Also in 2014, 106 (68%) catchment areas had MTCT = 0%. Geovisualization revealed clustering of catchment areas where both MTCT and the estimated number of HIV-infected infants were relatively high., Conclusion: Although MTCT is declining in Zimbabwe, geospatial analysis indicates facility-level variability. Catchment areas with high MTCT rates and a high burden of HIV-infected infants should be the highest priority for service intensification.

Objective: We evaluated the impact of Option A on HIV-free infant survival and mother-to-child transmission (MTCT) in Zimbabwe., Design: Serial cross-sectional community-based serosurveys., Methods: We analyzed serosurvey data collected in 2012 and 2014 among mother-infant pairs from catchment areas of 132 health facilities from five of 10 provinces in Zimbabwe. Eligible infants (alive or deceased) were born 9-18 months before each survey to mothers at least 16 years old. We randomly selected mother-infant pairs and conducted questionnaires, verbal autopsies, and collected blood samples. We estimated the HIV-free infant survival and MTCT rate within each catchment area and compared the 2012 and 2014 estimates using a paired t test and number of HIV infections averted because of the intervention., Results: We analyzed 7249 mother-infant pairs with viable maternal specimens collected in 2012 and 8551 in 2014. The mean difference in the catchment area level MTCT between 2014 and 2012 was -5.2 percentage points (95% confidence interval = -8.1, -2.3, P < 0.001). The mean difference in the catchment area level HIV-free survival was 5.5 percentage points (95% confidence interval = 2.6, 8.5, P < 0.001). Between 2012 and 2014, 1779 infant infections were averted compared with the pre-Option A regimen. The association between HIV-free infant survival and duration of Option A implementation was NS at the multivariate level (P = 0.093)., Conclusion: We found a substantial and statistically significant increase in HIV-free survival and decrease in MTCT among infants aged 9-18 months following Option A rollout in Zimbabwe. This is the only evaluation of Option A and shows the effectiveness of Option A and Zimbabwe's remarkable progress toward eMTCT.

Background: In developing countries, facility-based delivery is recommended for maternal and neonatal health, and for prevention of mother-to-child HIV transmission (PMTCT). However, little is known about whether or not learning one's HIV status affects one's decision to deliver in a health facility. We examined this association in Zimbabwe., Methods: We analyzed data from a 2012 cross-sectional community-based serosurvey conducted to evaluate Zimbabwe's accelerated national PMTCT program. Eligible women (≥16 years old and mothers of infants born 9-18 months before the survey) were randomly sampled from the catchment areas of 157 health facilities in five of ten provinces. Participants were interviewed about where they delivered and provided blood samples for HIV testing., Results: Overall 8796 (77 %) mothers reported facility-based delivery; uptake varied by community (30-100%). The likelihood of facility-based delivery was not associated with maternal HIV status. Women who self-reported being HIV-positive before delivery were as likely to deliver in a health facility as women who were HIV-negative, irrespective of when they learned their status - before (adjusted prevalence ratio (PRa) = 1.04, 95% confidence interval (CI) = 1.00-1.09) or during pregnancy (PRa = 1.05, 95% CI = 1.01-1.09). Mothers who had not accessed antenatal care or tested for HIV were most likely to deliver outside a health facility (69%). Overall, however 77% of home deliveries occurred among women who had accessed antenatal care and were HIV-tested., Conclusions: Uptake of facility-based delivery was similar among HIV-infected and HIV-uninfected mothers, which was somewhat unexpected given the substantial technical and financial investment aimed at retaining HIV-positive women in care in Zimbabwe.

Background: Food insecurity is an important barrier to retention in care and adherence to antiretroviral therapy (ART) among people living with HIV infection (PLHIV). However, there is a lack of rigorous evidence about how to improve food security and HIV-related clinical outcomes. To address this gap, this randomized trial will evaluate three delivery models for short-term food and nutrition support for food insecure PLHIV in Shinyanga, Tanzania: nutrition assessment and counseling (NAC) alone, NAC plus food assistance, and NAC plus cash transfers., Methods/design: At three HIV care and treatment sites, 788 participants will be randomized into one of three study arms in a 3:3:1 ratio, stratified by site: NAC plus food assistance, NAC plus cash transfer, and NAC only. Eligible participants are: 1) at least 18 years of age; 2) living with HIV infection; 3) initiated ART in the past 90 days; and 4) food insecure, as measured with the Household Hunger Scale. PLHIV who are severely malnourished (body mass index (BMI) < 16 kg/m(2)) will be excluded. Participants randomized to receive food or cash transfers are eligible to receive assistance for up to six months, conditional on attending regularly scheduled visits with their HIV care provider. Participants will be followed for 12 months: the initial 6-month intervention period and then for another 6 months post-intervention. The primary outcome is ART adherence measured with the medication possession ratio. Secondary outcomes include 1) retention in care; 2) nutritional indicators including changes in food security, BMI, and weight gain; 3) viral suppression and self-reported ART adherence; and 4) participation in the labor force., Discussion: This rigorously designed trial will inform policy decisions regarding supportive strategies for food insecure PLHIV in the early stages of treatment. The study will measure outcomes immediately after the period of support ends as well as 6 months later, providing information on the duration of the interventions' effect. The comparison of food to cash transfers will better inform policies favoring cash assistance or will provide rationale for the continued investment in food and nutrition interventions for PLHIV., Trial Registration: ClinicalTrials.gov: NCT01957917.

Objective: We estimated HIV-free infant survival and mother-to-child HIV transmission (MTCT) rates in Zimbabwe, some of the first community-based estimates from a UNAIDS priority country., Methods: In 2012 we surveyed mother-infant pairs residing in the catchment areas of 157 health facilities randomly selected from 5 of 10 provinces in Zimbabwe. Enrolled infants were born 9-18 months before the survey. We collected questionnaires, blood samples for HIV testing, and verbal autopsies for deceased mothers/infants. Estimates were assessed among i) all HIV-exposed infants, as part of an impact evaluation of Option A of the 2010 WHO guidelines (rolled out in Zimbabwe in 2011), and ii) the subgroup of infants unexposed to Option A. We compared province-level MTCT rates measured among women in the community with MTCT rates measured using program monitoring data from facilities serving those communities., Findings: Among 8568 women with known HIV serostatus, 1107 (12.9%) were HIV-infected. Among all HIV-exposed infants, HIV-free infant survival was 90.9% (95% confidence interval (CI): 88.7-92.7) and MTCT was 8.8% (95% CI: 6.9-11.1). Sixty-six percent of HIV-exposed infants were still breastfeeding. Among the 762 infants born before Option A was implemented, 90.5% (95% CI: 88.1-92.5) were alive and HIV-uninfected at 9-18 months of age, and 9.1% (95%CI: 7.1-11.7) were HIV-infected. In four provinces, the community-based MTCT rate was higher than the facility-based MTCT rate. In Harare, the community and facility-based rates were 6.0% and 9.1%, respectively., Conclusion: By 2012 Zimbabwe had made substantial progress towards the elimination of MTCT. Our HIV-free infant survival and MTCT estimates capture HIV transmissions during pregnancy, delivery and breastfeeding regardless of whether or not mothers accessed health services. These estimates also provide a baseline against which to measure the impact of Option A guidelines (and subsequently Option B+).

A growing body of research has identified food insecurity as a barrier to antiretroviral therapy (ART) adherence. We systematically reviewed and summarized the quantitative literature on food insecurity or food assistance and ART adherence. We identified nineteen analyses from eighteen distinct studies examining food insecurity and ART adherence. Of the thirteen studies that presented an adjusted effect estimate for the relationship between food insecurity and ART adherence, nine found a statistically significant association between food insecurity and sub-optimal ART adherence. Four studies examined the association between food assistance and ART adherence, and three found that ART adherence was significantly better among food assistance recipients than non-recipients. Across diverse populations, food insecurity is an important barrier to ART adherence, and food assistance appears to be a promising intervention strategy to improve ART adherence among persons living with HIV. Additional research is needed to determine the effectiveness and cost-effectiveness of food assistance in improving ART adherence and other clinical outcomes among people living with HIV in the era of widespread and long-term treatment.

Objective: To examine the uptake of services and behaviors in the prevention of mother-to-child HIV transmission (PMTCT) cascade in Zimbabwe and to determine factors associated with MTCT and maternal antiretroviral therapy (ART) or antiretroviral (ARV) prophylaxis., Design: Analysis of cross-sectional data from mother-infant pairs., Methods: We analyzed baseline data collected in 2012 as part of the impact evaluation of Zimbabwe's Accelerated National PMTCT Program. Using multistage cluster sampling, eligible mother-infant pairs were randomly sampled from the catchment areas of 157 facilities in 5 provinces, tested for HIV infection, and interviewed about PMTCT service utilization., Results: Of 8800 women, 94% attended ≥ 1 antenatal care visit, 92% knew their HIV serostatus during pregnancy, 77% delivered in a health facility, and 92% attended the 6-8 week postnatal visit. Among 1075 (12%) HIV-infected women, 59% reported ART/ARV prophylaxis and 63% of their HIV-exposed infants received ARV prophylaxis. Among HIV-exposed infants, maternal receipt of ART/ARV prophylaxis was protective against MTCT [adjusted prevalence ratio (PR(a)): 0.41, 95% confidence interval (CI): 0.23 to 0.74]. Factors associated with receipt of maternal ART/ARV prophylaxis included ≥ 4 antenatal care visits (PR(a): 1.18, 95% CI: 1.01 to 1.38), institutional delivery (PR(a): 1.31, 95% CI: 1.13 to 1.52), and disclosure of serostatus (PRa: 1.30, 95% CI: 1.12 to 1.49)., Conclusions: These data from women in the community indicate gaps in the PMTCT cascade before the accelerated program, which may have been missed by examination of health facility data alone. These gaps were especially noteworthy for services targeted specifically to HIV-infected women and their infants, such as maternal and infant ART/ARV prophylaxis.

Background: Food insecurity (FI) is the lack of physical, social, and economic access to sufficient food for dietary needs and food preferences. We examined the association between FI and women's uptake of services to prevent mother-to-child HIV transmission (MTCT) in Zimbabwe., Methods: We analyzed cross-sectional data collected in 2012 from women living in five of ten provinces. Eligible women were ≥16 years old, biological mothers of infants born 9-18 months before the interview, and were randomly selected using multi-stage cluster sampling. Women and infants were tested for HIV and interviewed about health service utilization during pregnancy, delivery, and post-partum. We assessed FI in the past four weeks using a subset of questions from the Household Food Insecurity Access Scale and classified women as living in food secure, moderately food insecure, or severely food insecure households., Results: The weighted population included 8,790 women. Completion of all key steps in the PMTCT cascade was reported by 49%, 45%, and 38% of women in food secure, moderately food insecure, and severely food insecure households, respectively (adjusted prevalence ratio (PRa) = 0.95, 95% confidence interval (CI): 0.90, 1.00 (moderate FI vs. food secure), PRa = 0.86, 95% CI: 0.79, 0.94 (severe FI vs. food secure)). Food insecurity was not associated with maternal or infant receipt of ART/ARV prophylaxis. However, in the unadjusted analysis, among HIV-exposed infants, 13.3% of those born to women who reported severe household food insecurity were HIV-infected compared to 8.2% of infants whose mothers reported food secure households (PR = 1.62, 95% CI: 1.04, 2.52). After adjustment for covariates, this association was attenuated (PRa = 1.42, 95% CI: 0.89, 2.26). There was no association between moderate food insecurity and MTCT in unadjusted or adjusted analyses (PRa = 0.68, 95% CI: 0.43, 1.08)., Conclusions: Among women with a recent birth, food insecurity is inversely associated with service utilization in the PMTCT cascade and severe household food insecurity may be positively associated with MTCT. These preliminary findings support the assessment of FI in antenatal care and integrated food and nutrition programs for pregnant women to improve maternal and child health.

Background: The evidence from epidemiological research into whether use of hormonal contraception increases women's risk of HIV acquisition is inconsistent. We did a robust meta-analysis of existing data to provide summary estimates by hormonal contraceptive method which can be used to inform contraceptive guidelines, models, and future studies., Methods: We updated a recent systematic review to identify and describe studies that met inclusion criteria. To ensure inclusion of more recent research, we searched PubMed for articles published after December, 2011, using the terms "hormonal contraception", "HIV/acquisition", "injectables", "progestin", and "oral contraceptive pills". We assessed statistical heterogeneity for these studies, and, when appropriate, combined point estimates by hormonal contraception formulation using random-effects models. We assessed publication bias and investigated heterogeneity through subgroup and stratified analyses according to study population and design features., Findings: We identified 26 studies, 12 of which met inclusion criteria. There was evidence of an increase in HIV risk in the ten studies of depot medroxyprogesterone acetate (pooled hazard ratio [HR] 1·40, 95% CI 1·16-1·69). This risk was lower in the eight studies done in women in the general population (pooled HR 1·31, 95% CI 1·10-1·57). There was substantial between-study heterogeneity in secondary analyses of trials (n=7, I(2) 51·1%, 95% CI 0-79·3). Although individual study estimates suggested an increased risk, substantial heterogeneity between two studies done in women at high risk of HIV infection (I(2) 54%, 0-88·7) precluded pooling estimates. There was no evidence of an increased HIV risk in ten studies of oral contraceptive pills (pooled HR 1·00, 0·86-1·16) or five studies of norethisterone enanthate (pooled HR 1·10, 0·88-1·37)., Interpretation: Our findings show a moderate increased risk of HIV acquisition for all women using depot medroxyprogesterone acetate, with a smaller increase in risk for women in the general population. Whether the risks of HIV observed in our study would merit complete withdrawal of depot medroxyprogesterone acetate needs to be balanced against the known benefits of a highly effective contraceptive., Funding: None., (Copyright © 2015 Elsevier Ltd.

We analyzed biomarker validation data of unprotected sex from women in Zimbabwe to determine whether condom and sexual behavior misreporting differs between users of different contraceptive methods. Self-reported sexual behavior was compared with the presence of prostate-specific antigen (PSA) in vaginal fluid, a biomarker of semen exposure. Of the 195 women who were PSA positive, 94 (48 %) reported no sex or only condom-protected sex. Hormonal contraceptive users misreported sexual behavior less than women using non-hormonal methods (45 vs. 67 %, P = 0.03). This misclassification pattern could have implications on the elevated risk of HIV infection associated with hormonal contraception in some studies.

Adherence to antiretroviral therapy (ART) is critical for reducing HIV/AIDS morbidity and mortality. Food insecurity (FI) is emerging as an important barrier to adherence to care and treatment recommendations for people living with HIV (PLHIV), but this relationship has not been comprehensively examined. Therefore, we reviewed the literature to explore how FI may impact ART adherence, retention in medical care, and adherence to health care recommendations among PLHIV. We found data to support FI as a critical barrier to adherence to ART and to other health care recommendations among HIV-infected adults, HIV-infected pregnant women and their HIV-exposed infants, and child and adolescent populations of PLHIV. Associations between FI and ART non-adherence were seen in qualitative and quantitative studies. We identified a number of mechanisms to explain how food insecurity and ART non-adherence may be causally linked, including the exacerbation of hunger or ART side effects in the absence of adequate food and competing resource demands. Interventions that address FI may improve adherence to care and treatment recommendations for PLHIV.

Background: Prevention of unintended pregnancies among women living with HIV infection is a strategy recommended by the World Health Organization for prevention of mother-to-child transmission of HIV (PMTCT). We assessed pregnancy intentions and contraceptive use among HIV-positive and HIV-negative women with a recent pregnancy in Zimbabwe., Methods: We analyzed baseline data from the evaluation of Zimbabwe's Accelerated National PMTCT Program. Eligible women were randomly sampled from the catchment areas of 157 health facilities offering PMTCT services in five provinces. Eligible women were ≥16 years old and mothers of infants (alive or deceased) born 9 to 18 months prior to the interview. Participants were interviewed about their HIV status, intendedness of the birth, and contraceptive use., Results: Of 8,797 women, the mean age was 26.7 years, 92.8% were married or had a regular sexual partner, and they had an average of 2.7 lifetime births. Overall, 3,090 (35.1%) reported that their births were unintended; of these women, 1,477 (47.8%) and 1,613 (52.2%) were and were not using a contraceptive method prior to learning that they were pregnant, respectively. Twelve percent of women reported that they were HIV-positive at the time of the survey; women who reported that they were HIV-infected were significantly more likely to report that their pregnancy was unintended compared to women who reported that they were HIV-uninfected (44.9% vs. 33.8%, p<0.01). After adjustment for covariates, among women with unintended births, there was no association between self-reported HIV status and lack of contraception use prior to pregnancy., Conclusions: Unmet need for family planning and contraceptive failure contribute to unintended pregnancies among women in Zimbabwe. Both HIV-infected and HIV-uninfected women reported unintended pregnancies despite intending to avoid or delay pregnancy, highlighting the need for effective contraceptive methods that align with pregnancy intentions.

Food insecurity (FI) is associated with higher-risk sexual behavior in some studies. However, the overlap between FI and socioeconomic status (SES) has been poorly described. The study objectives were to: (1) determine the relationship between household FI and four dimensions of SES among sexually active Tanzanian women in farming households: expenditures, assets, flooring material of the home, and land ownership; and (2) determine whether FI is associated with higher-risk sexual behavior and relationship power. In male-headed households, FI was associated with assets, flooring material, and land ownership but not expenditures. There was no association between FI and the four dimensions of SES in female-headed households. Among women in male-headed households, but not female household heads themselves, severe FI was associated with a non-significant increase in the likelihood of being in a relationship because of material goods [adjusted prevalence ratio (PRa) = 1.76, 95 % confidence interval (CI) 0.81, 3.81] and was inversely associated with being able to ask partners to use condoms (PRa = 0.47, 95 % CI 0.25, 0.88). There was not a strong association between food security and relationship power. Our findings suggest that the association between FI and HIV risk behavior may differ depending on the type of household.

Background: The authors piloted an HIV testing and counseling (HTC) approach using respondent-driven sampling (RDS), financial incentives, and persons living with HIV infection (PLHIV)., Methods: Eligible participants were aged 30-60 years, African American or black, and residents of Oakland, CA. Participants were tested for HIV infection and asked to refer up to 3 others. The authors compared the efficiency of RDS to conventional outreach-based HTC with the number needed to screen (NNS). They evaluated the effect of 2 randomly allocated recruitment incentives on the enrollment of high-risk or HIV-positive network associates: a flat incentive ($20) for eligible recruits or a conditional incentive ($10-35) for eligible recruits in priority groups, such as first-time testers., Results: Forty-eight participants (10 PLHIV and 38 HIV negative) initiated recruitment chains resulting in 243 network associates. Nine (3.7%) participants tested HIV positive, of whom 7 (78%) were previously recognized. RDS was more efficient than conventional HTC at identifying any PLHIV (new or previously recognized; RDS: NNS = 27, 95% CI: 14 to 59; conventional: NNS = 154, 95% CI: 95 to 270). There was no difference between the 2 incentive groups in the likelihood of recruiting at least 1 high-risk HIV-negative or HIV-positive network associate (adjusted odds ratio = 0.89, 95% CI: 0.06 to 13.06) or in total number of high-risk HIV-negative or HIV-positive associates (adjusted odds ratio = 0.79, 95% CI: 0.23 to 2.71)., Conclusions: Social network HTC strategies may increase demand for HTC and efficiently identify PLHIV. The flat incentive was as successful as the conditional incentive for recruiting high-risk individuals. Unexpectedly, this method also reidentified PLHIV aware of their status.

Objective: To evaluate the effect of oral and injectable hormonal contraception on the risk of HIV acquisition among women in South Africa and Zimbabwe., Design: Secondary data analysis of 4913 sexually active women aged 18-49 years followed for up to 24 months in the Methods for Improving Reproductive Health in Africa (MIRA) phase III effectiveness trial of the diaphragm and lubricant gel for HIV prevention., Methods: Participants were interviewed quarterly about contraception and sexual behavior and were tested for pregnancy, HIV, and other sexually transmitted infections. We used a Cox proportional hazards marginal structural model, weighted by the inverse probability of hormonal contraception use, to compare the risk of HIV acquisition among nonpregnant women reporting use of combined oral contraceptive pills (COC), progestin-only pills (POP), and/or injectable hormonal contraception to women not using these methods., Results: During the study, 283 participants seroconverted. Use of oral contraceptives (POP or COC) was not associated with HIV risk [adjusted hazard ratio (HRa) = 0.86, 95% confidence interval (CI) 0.32, 1.78]. Injectable hormonal contraception was associated with a small nonsignificant risk of HIV infection (HR(a) = 1.34, 95% CI 0.75, 2.37). The effect of injectable hormonal contraception was similar in the unweighted site-adjusted only (HR(a) = 1.32, 95% CI 1.00, 1.74) and baseline factor adjusted models (HR(a) = 1.27, 95% CI 0.94, 1.72)., Conclusions: In this study, oral contraceptives were not associated with HIV acquisition. There is substantial uncertainty in the effect of injectable hormonal contraception on HIV risk. These findings underscore the importance of dual protection with condoms and the need for diverse contraceptive options for women at risk of HIV infection.

Background: We assessed the association between dietary diversity and CD4 count, moderate anemia, and mortality among 876 antiretroviral therapy-naive people living with HIV/AIDS infection (PLHIV) in Uganda., Methods: Participants were interviewed and followed for an average of 21.6 months. Dietary diversity was measured using the Individual Dietary Diversity Score (IDDS) (range, 0-12) and summarized into an overall measure and disaggregated into nutrient-rich food groups (range, 0-7), cereals, roots, and tubers (range, 0\x{2013} 2); and oils, fats, sugars, and condiments (range, 0\x{2013} 3). We determined the cross-sectional associations between dietary diversity and (1) immunosuppression (CD4 count ≤ 350 cells/μL) and (2) moderate anemia (hemoglobin < 10 g/dL) at baseline with logistic regression. We assessed the association between IDDS and mortality using Cox proportional hazards regression., Results: The mean IDDS score was 6.3 (SD 1.7) food groups per day, with a mean of 2.7 (SD 1.1) nutrient-rich food groups per day. Each additional nutrient-rich food group consumed was associated with a 16% reduction in the likelihood of having a CD4 count ≤350 cells/μL [adjusted odds ratio, 0.84; 95% confidence interval (CI): 0.72 to 0.97] at baseline. Among those with >350 CD4 cells per microliter, but not those with CD4 count ≤350 cells per microliter, consumption of nutrient-rich food groups was associated with a lower odds of moderate anemia (adjusted odds ratio, 0.57; 95% CI: 0.34 to 0.96). During follow-up, 48 participants (5.6%) died (mortality rate of 3.1 per 100 person-years). IDDS was inversely associated with mortality [adjusted hazard ratio, 0.76; 95% CI: 0.63 to 0.91]., Conclusion: These results suggest that diet quality is an important determinant of HIV disease severity and mortality in antiretroviral therapy-naive PLHIV.

Background: Although women occupy a central position in agriculture in many developing countries, they face numerous constraints to achieving their full potential including unequal access to assets and limited decision-making authority. We explore the intersection of agricultural livelihoods, food and economic security, and women's sexual and reproductive health in Iringa Region, Tanzania. Our goal was to understand whether the benefits of supporting women in the agricultural sector might also extend to more distal outcomes, including sexual and reproductive health., Methods: Using the Sustainable Livelihoods Framework to guide data collection, we conducted 13 focus group discussions (FGD) with female (n = 11) and male farmers (n = 2) and 20 in-depth interviews with agricultural extension officers (n = 10) and village agro-dealers (n = 10)., Results: Despite providing the majority of agricultural labor, women have limited control over land and earned income and have little bargaining power. In response to these constraints, women adopt adaptive livelihood strategies, such as alcohol production, that allow them to retain control over income and support their households. However, women's central role in alcohol production, in concert with the ubiquitous nature of alcohol consumption, places them at risk by enhancing their vulnerability to unsafe or transactional sex. This represents a dangerous confluence of risk for female farmers, in which alcohol plays an important role in income generation and also facilitates high-risk sexual behavior., Conclusions: Alcohol production and consumption has the potential to both directly and indirectly place women at risk for undesirable sexual and reproductive health outcomes. Group formation, better access to finance, and engaging with agricultural extension officers were identified as potential interventions for supporting women farmers and challenging harmful gender norms. In addition, joint, multi-sectoral approaches from health and agriculture and alternative income-generating strategies for women might better address the complexities of achieving safe and sustainable livelihoods for women in this context.
