Challenging the assumption that experience- and training-related factors improve accuracy of cervical cancer screening image interpretation
Visual inspection of the cervix with acetic acid (VIA), although recognized as inaccurate, remains widely used for cervical screening in low-resource settings. Training and image review by more experienced providers − such as the smartphone-enhanced VIA (SEVIA) in Tanzania − are assumed to improve VIA performance, but remain untested against a reference standard of disease. Between June and December 2023, 486 VIA providers in Tanzania completed a…
Adapting a Stigma-Reduction Workshop for Adolescent Sexual and Reproductive Health and Contraceptive Stigma in Kilimanjaro, Tanzania
Background Although contraception is free of charge in Tanzania, adolescent girls and young women (AGYW) often avoid seeking services due to stigma and moral judgments around adolescent sexuality. Existing stigma-reduction programs in Tanzania primarily target HIV-related stigma in clinical settings and have not been tailored to the unique social context of sexual and reproductive health (SRH) and contraceptive stigma in youth populations. Object…
The relationship between rural residence and cervical cancer screening in three sub-Saharan countries with different national screening policies
PURPOSE: To compare cervical cancer screening prevalence between urban and rural women aged 30-49 years in three sub-Saharan African countries chosen by their country-specific screening strategy (Burkina Faso, which has a systematic population-based cervical cancer screening programme in place; Tanzania, where opportunistic screening options only are implemented; and Ghana, which has implemented neither one). METHODS: We used the most recent Demo…
In the Village That She Comes from, Most of the People Don’t Know Anything about Cervical Cancer”
Our results demonstrate that there is a low level of knowledge of the role of screening and preventive services among stakeholders, HCPs, and women living in rural and semi-rural locations in Tanzania. There is a critical need to implement more initiatives and programs to increase the uptake of screening and related services and allow women to make more informed decisions on their health
An Implementation Evaluation of the Smartphone-Enhanced Visual Inspection with Acetic Acid (Sevia) Program for Cervical Cancer Prevention in Urban and Rural Tanzania
SEVIA is a practical and feasible mobile health intervention and tool that is easily integrated into the National CCS program to enhance the quality of care
Comparing estimates of household expenditures between pictorial diaries and surveys in three low- and middle-income countries
In most low- and middle-income countries (LMICs), household out-of-pocket (OOP) health spending constitutes a major source of healthcare financing. Household surveys are commonly used to monitor OOP health spending, but are prone to recall bias and unable to capture seasonal variation, and may underestimate expenditure–particularly among households with long-term chronic health conditions. Household expenditure diaries have been developed as an a…
Perceived built environment characteristics associated with walking and cycling across 355 communities in 21 countries
Differences and agreement between two portable hand-held spirometers across diverse community-based populations in the Prospective Urban Rural Epidemiology (Pure) study
Introduction Portable spirometers are commonly used in longitudinal epidemiological studies to measure and track the forced expiratory volume in first second (FEV 1 ) and forced vital capacity (FVC). During the course of the study, it may be necessary to replace spirometers with a different model. This raise questions regarding the comparability of measurements from different devices. We examined the correlation, mean differences and agreement be…
Impact of social isolation on mortality and morbidity in 20 high-income, middle-income and low-income countries in five continents
OBJECTIVE: To examine the association between social isolation and mortality and incident diseases in middle-aged adults in urban and rural communities from high-income, middle-income and low-income countries. DESIGN: Population-based prospective observational study. SETTING: Urban and rural communities in 20 high income, middle income and low income. PARTICIPANTS: 119 894 community-dwelling middle-aged adults. MAIN OUTCOME MEASURES: Associations…
Modifiable risk factors, cardiovascular disease, and mortality in 155 722 individuals from 21 high-income, middle-income, and low-income countries (Pure)
Availability and affordability of medicines and cardiovascular outcomes in 21 high-income, middle-income and low-income countries
OBJECTIVES: We aimed to examine the relationship between access to medicine for cardiovascular disease (CVD) and major adverse cardiovascular events (MACEs) among people at high risk of CVD in high-income countries (HICs), upper and lower middle-income countries (UMICs, LMICs) and low-income countries (LICs) participating in the Prospective Urban Rural Epidemiology (PURE) study. METHODS: We defined high CVD risk as the presence of any of the foll…
The household economic burden of non-communicable diseases in 18 countries
Background: Non-communicable diseases (NCDs) are the leading cause of death globally. In 2014, the United Nations committed to reducing premature mortality from NCDs, including by reducing the burden of healthcare costs. Since 2014, the Prospective Urban and Rural Epidemiology (PURE) Study has been collecting health expenditure data from households with NCDs in 18 countries. Methods: Using data from the PURE Study, we estimated risk of catastroph…
Socioeconomic status and risk of cardiovascular disease in 20 low-income, middle-income, and high-income countries
Background Socioeconomic status is associated with differences in risk factors for cardiovascular disease incidence and outcomes, including mortality. However, it is unclear whether the associations between cardiovascular disease and common measures of socioeconomic status—wealth and education—differ among high-income, middle-income, and low-income countries, and, if so, why these differences exist. We explored the association between education a…
Household, community, sub-national and country-level predictors of primary cooking fuel switching in nine countries from the Pure study
The importance of community and sub-national factors relative to household characteristics in determining polluting-to-clean fuel switching varied dramatically across the nine countries examined. This highlights the potential importance of national and other contextual factors in shaping large-scale clean cooking transitions among rural communities in low- and middle-income countries
Process evaluation in the field
This research demonstrates the important role of process evaluation in understanding implementation process of complex interventions. This can help to highlight a broad range of system requirements such as new policies and capacity building to support implementation. Process evaluation is crucial in understanding contextual factors that may impact intervention implementation which is important in considering whether or not the intervention can be…
Wealth and cardiovascular health
Inequality in hypertension management outcomes decreased as countries became richer, but the considerable variation in patterns of wealth-related inequality - even among countries at similar levels of economic development - underscores the importance of health systems in improving hypertension management for all. These findings show that some, but not all, countries, including those with limited resources, have been able to achieve more equitable…
