Determinants of knowledge and attitudes toward personal protective equipment use among commercial motorcycle riders in a conflict-affected region of Cameroon
Background: Road traffic injuries are a leading cause of death globally, disproportionately affecting motorcyclists in low- and middle-income countries (LMICs). Personal protective equipment (PPE) such as helmets and visibility materials substantially reduce injury severity, yet their consistent use remains suboptimal in many African settings. In conflict-affected areas, where displacement and informal transport systems are common, safety behavio…
How do repeated financial incentives affect HIV care-seeking behaviours over time? Evidence from a cluster-randomised controlled trial
BACKGROUND: A more nuanced understanding of behavioural responses to incentives over time, particularly after they are removed, could guide more effective interventions. In this study, we build on the primary trial evaluation to explore the dynamic effectiveness of small, short-term monthly financial incentives on HIV care-seeking behaviours during and after incentive removal. METHODS: We conducted a 32-site cluster-randomised controlled trial (N…
Epidemiological patterns of motorcycle-related injuries in Cameroon
Motorcycles are a common mode of transport in major Cameroonian cities, contributing to a rising burden of injuries among both users and pedestrians. These groups differ in exposure, mechanisms, and vulnerability, yet both bear a disproportionately high injury burden. However, comparative data on their epidemiological patterns and outcomes remain scarce. To support targeted prevention policies, we analysed trauma registry data to describe demogra…
Epidemiological profile of road traffic injury patients, and post-traumatic stress disorder (PTSD) screening uptake in hospitals in Fako Division, Cameroon
Road traffic injuries (RTIs) are a major global public health concern, often leading to serious physical and psychological consequences, including post-traumatic stress disorder (PTSD). A limited understanding of specific RTI patient characteristics, particularly regarding PTSD screening recommendation and uptake in health facilities in Cameroon, hinders the development of effective PTSD management strategies. This study aimed to determine the ep…
Impact of Financial Incentives on Intimate Partner Violence for Women Living with HIV Initiating Antiretroviral Therapy
Financial incentives have demonstrated effectiveness in improving outcomes for people living with HIV; however, little is known about their impact on intimate partner violence (IPV) in this vulnerable population. A cluster-randomized trial investigating financial incentives and viral suppression was conducted in the Lake Zone of Tanzania (clinicaltrials.gov: NCT0420135). Between May 2021-March 2022, 32 clinics were randomized 1:1 to receive the s…
Effect of a Gender-Synchronized Family Planning Intervention on Inequitable Gender Norms in a Cluster Randomized Control Trial Among Husbands of Married Adolescent Girls in Dosso, Niger
Gender inequitable norms have severe consequences for safety and health globally. Using data from a four-arm cluster randomized control trial of the Reaching Married Adolescents in Niger (RMA) intervention (2016-2019), this study assesses effects on gender norms among husbands of married adolescent girls ( n = 1,055). Using an adjusted hierarchical difference-in-differences model, we found assignment to the RMA small groups intervention to be ass…
A Systematic Review of HIV Pre-exposure Prophylaxis (PrEP) Implementation in U.S. Emergency Departments
In the pursuit of ending the HIV epidemic, U.S. emergency departments (EDs) have emerged as a valuable setting to increase HIV testing and linkage to care. There is limited data available, however, describing the incorporation of HIV prevention initiatives in U.S. EDs. Over the last decade, HIV pre-exposure prophylaxis (PrEP) has significantly changed the HIV prevention landscape globally and very little is known about the provision of PrEP in U.…
Who seeks care after intimate partner violence in Cameroon? sociodemographic differences between a hospital and population sample of women
Introduction Little is known regarding health care seeking behaviors of women in sub-Saharan Africa, specifically Cameroon, who experience violence. The proportion of women who experienced violence enrolled in the Cameroon Trauma Registry (CTR) is lower than expected. Methods We concatenated the databases from the October 2017-December 2020 CTR and 2018 Cameroon Demographic and Health Survey (DHS) into a singular database for cross-sectional stud…
The impact of cash incentives on mental health among adults initiating antiretroviral therapy in Tanzania
Mental illness is prevalent among people living with HIV (PLHIV) and hinders engagement in HIV care. While financial incentives are effective at improving mental health and retention in care, the specific effect of such incentives on the mental health of PLHIV lacks quantifiable evidence. We evaluated the impact of a three-arm randomized controlled trial of a financial incentive program on the mental health of adult antiretroviral therapy (ART) i…
Age-disparate relationships at first sex and reproductive autonomy, empowerment, and sexual violence among adolescent girls and young women in Rwanda
Our results suggest a high prevalence of sexual violence among AGYW engaging in first sex with an age-disparate partner. However, we did not find evidence that ADR at first sex affects reproductive autonomy or empowerment within the first few years of sexual initiation. Further research is needed to explore the impact of ADR at first sex and longer-term trajectories of sexual behavior, empowerment and autonomy
Effect of a Lottery Intervention on Gender-Based Violence among Female Sex Workers in Dar es Salaam, Tanzania
Financial incentives are a promising approach for HIV prevention. Some studies have shown that financial incentive interventions aimed to promote positive health and social behaviors have mixed or harmful effects on gender-based violence, and little is known about their effects among higher risk groups such as female sex workers. To address this gap, this study investigated the relationship between a lottery-based incentive and gender-based viole…
Financial incentives to improve re-engagement in HIV care
Objective Determine the feasibility, acceptability, and preliminary effectiveness of financial incentives to motivate re-engagement in HIV care in Shinyanga, Tanzania.Methods Out-of-care people living with HIV (PLHIV) were identified from medical records in four clinics and home-based care providers (HBCs) from April 13, 2018 to March 3, 2020. Shinyanga Region residents, ≥18 years, who were disengaged from care were randomized 1:1 to a financial …
Risks of Intimate Partner Violence for Women Living with HIV Receiving Cash Transfers
Cash transfers are increasingly used to motivate adherence to HIV care. However, evidence on cash transfers and intimate partner violence (IPV) is mixed and little is known about their safety for women living with HIV. We conducted in-depth interviews with women living with HIV who participated in a randomized trial providing 6 months of cash transfers (~$4.5 or $11 USD) conditional on HIV clinic attendance in Shinyanga, Tanzania to assess how re…
Food Insecurity and Engagement in Transactional Sex Among Female Secondary Students in Rwanda
The relationship between food insecurity and transactional sex is well recognized, but less is known about this relationship among adolescents. We analyzed cross-sectional baseline data from 3,130 female secondary students aged 12-19 enrolled in a three-arm, cluster randomized controlled trial to examine the association between food insecurity and transactional sex. The explanatory variable was food security and the outcome was ever engaging in t…

Machine learning with routine electronic medical record data to identify people at high risk of disengagement from HIV care in Tanzania
Machine learning methods for health care delivery optimization have the potential to improve retention in HIV care, a critical target of global efforts to end the epidemic. However, these methods have not been widely applied to medical record data in low- and middle-income countries. We used an ensemble decision tree approach to predict risk of disengagement from HIV care (missing an appointment by ≥28 days) in Tanzania. Our approach used routine…
Covid-19 outbreak in a state prison
Our adapted framework facilitates systematically assessing prison-based infectious disease outbreaks and multi-level interventions. We find implementing some recommended public health strategies may have contributed to outbreak containment. However, even with a rapidly mobilized, inter-institutional response, failure to decarcerate created an overreliance on chance conditions. This left the facility vulnerable to future catastrophic outbreaks and…
Durability of effects from short-term economic incentives for clinic attendance among HIV positive adults in Tanzania
INTRODUCTION: Conditional economic incentives are shown to promote medication adherence across a range of health conditions and settings; however, any long-term harms or benefits from these time-limited interventions remain largely unevaluated. We assessed 2-3 years outcomes from a 6-month incentive programme in Tanzania that originally improved short-term retention in HIV care and medication possession. METHODS: We traced former participants in …
Transportation cost as a barrier to contraceptive use among women initiating treatment for HIV in Tanzania
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-…
Heavy Load Carrying and Symptoms of Pelvic Organ Prolapse among Women in Tanzania and Nepal
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 heav…
Designing drug shops for young women in Tanzania
Adolescent and young adult women in sub-Saharan Africa experience barriers to sexual and reproductive health (SRH) services that elevate their risk of human immunodeficiency virus (HIV) acquisition and unintended pregnancy. Community drug shops may be effective distribution points to connect young women with SRH products. Thus, we used human-centred design (HCD) to create drug shops where young women could access HIV self-testing and contraceptio…
Measuring Family Planning Provider Bias
The unmet need for modern contraception remains high around the world, particularly for youth. While some of this unmet need is driven by limited health infrastructure and method mix availability, many adolescents who visit family planning providers still do not receive methods that fit their needs. This suggests that providers may be biased against youth and that interventions to change provider behavior could help close this gap. However, it is…

Female sex workers use power over their day-to-day lives to meet the condition of a conditional cash transfer intervention to incentivize safe sex
Barriers and facilitators to HIV testing and linkage to primary care
Persons with unrecognized HIV infection forgo timely clinical intervention and may unknowingly transmit HIV to partners. However, in the USA, unrecognized infection and late diagnosis are common. To understand barriers and facilitators to HIV testing and care, we conducted a qualitative study of 24 HIV infected persons attending a Southeastern HIV clinic who presented with clinically advanced illness. The primary barrier to HIV testing prior to d…
Social support and delays seeking care after HIV diagnosis, North Carolina, 2000–2006
Many adults in the USA enter primary care late in the course of HIV infection, countering the clinical benefits of timely HIV services and missing opportunities for risk reduction. Our objective was to determine if perceived social support was associated with delay entering care after an HIV diagnosis. Two hundred and sixteen patients receiving primary care at a large, university-based HIV outpatient clinic in North Carolina were included in the …

Food insecurity is a barrier to prevention of mother-to-child HIV transmission services in Zimbabwe
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
Women’s Relationship Power Modifies the Effect of a Randomized Conditional Cash Transfer Intervention for Safer Sex in Tanzania
Female sex workers use power over their day-to-day lives to meet the condition of a conditional cash transfer intervention to incentivize safe sex
The heterogeneous effect of short-term transfers for improving ART adherence among HIV-infected Tanzanian adults
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 …
