Key Components of Parenting Education Interventions for Preterm Infant–Parent Dyads Admitted to the Nicu
NICU educational interventions positively influence parental knowledge, confidence, and parent-infant interaction; however, substantial variation and limited conceptual grounding hinder their comparability and scalability. The evidence base remains dominated by high-income settings, which limits its global applicability. Future research must prioritise theory-informed design, transparent reporting, and context-sensitive adaptation, particularly i…
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…
Strategies of Modelling Incident Outcomes Using Cox Regression to Estimate the Population Attributable Risk
When the Cox model is applied, some recommendations about the choice of the time metric and the model's structure are often disregarded along with the proportionality of risk assumption. Moreover, most of the published studies fail to frame the real impact of a risk factor in the target population. Our aim was to show how modelling strategies affected Cox model assumptions. Furthermore, we showed how the Cox modelling strategies affected the popu…
Noncommunicable Disease Conditions and HIV in Rural and Urban South Africa
Although average blood pressure of urban hypertensive individuals decreased, urgent measures focused on early identification, treatment, and control of the respective conditions should be implemented to decrease the burden of noncommunicable diseases
Perceived built environment characteristics associated with walking and cycling across 355 communities in 21 countries
The Metabolic Profiles of Metabolically Healthy Obese and Metabolically Unhealthy Obese South African Adults over 10 Years
Obesity is associated with an increased cardiometabolic risk, but some individuals maintain metabolically healthy obesity (MHO). The aims were to follow a cohort of black South African adults over a period of 10 years to determine the proportion of the group that maintained MHO over 10 years, and to compare the metabolic profiles of the metabolically healthy and metabolically unhealthy groups after the follow-up period. The participants were Sout…
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…
The association between anthropometric measures and physical performance in black adults of the North West Province, South Africa
OBJECTIVE: This study investigated associations between anthropometric measures and physical performance in black South African adults. It was hypothesized that noninvasive, simple anthropometric measurements, such as calf circumference (CC) and body mass index (BMI), may be useful predictors of physical performance and strength. METHODS: Black human immunodeficiency virus (HIV) negative men and women (aged 32-93 years) participating in the Prosp…
Education, Smoking and CRP Genetics in Relation to C-Reactive Protein Concentrations in Black South Africans
Because elevated circulating C-reactive protein (CRP) and low socio-economic status (SES), have both been implicated in cardiovascular disease development, we investigated whether SES factors associate with and interact with CRP polymorphisms in relation to the phenotype. Included in the study were 1569 black South Africans for whom CRP concentrations, 12 CRP single nucleotide polymorphisms (SNPs), cardiovascular health markers, and SES factors w…
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…
Coverage and factors associated with vitamin A supplementation among children aged 6–59 months in twenty-three sub-Saharan African countries
Objective The present study aimed to give an overall view of the pattern of high-dose vitamin A supplementation (VAS) coverage in twenty-three sub-Saharan African countries and factors associated with receipt of VAS among children aged 6–59 months. Design Cross-sectional data from the twenty-three Demographic and Health Surveys conducted from 2011 to 2015 in twenty-three sub-Saharan African countries were pooled. A multilevel logistic regression …
CRP Genotypes Predict Increased Risk to Co-Present with Low Vitamin D and Elevated CRP in a Group of Healthy Black South African Women
Low 25-hydroxyvitamin D (25(OH)D) and elevated C-reactive protein (CRP) concentrations are independently associated with adverse health outcomes, including cardiovascular disease (CVD). Although an inverse association between these factors has been described, the underlying mechanisms remain unknown. We postulate that environment-gene interactions, through which 25(OH)D interacts with single nucleotide polymorphisms (SNPs) within the CRP gene, mo…
Socio-Demographic and Lifestyle Factors Predict 5-Year Changes in Adiposity among a Group of Black South African Adults
The rising prevalence of obesity and excessive adiposity are global public health concerns. Understanding determinants of changes in adiposity over time is critical for informing effective evidence-based prevention or treatment. However, limited information is available to achieve this objective. Cultural, demographic, environmental, and behavioral factors including socio-economic status (SES) likely account for obesity development. To this end, …
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…
