Early and young child feeding in South Africa
Stunting under the age of two years remains a significant public health problem in South Africa. This study used data from the 2023/24 Food-EPI assessment to benchmark implementation of public nutrition policy related to undernutrition to develop recommendations for priority policy action. The assessment included ratings by an expert panel including academics, civil society, and government representatives (n = 13). Implementation of food fortific…
Tool for assessing food industry commitments and practices to address the double burden of malnutrition
BACKGROUND: Many low- and middle-income countries face a double burden of malnutrition, i.e., a co-occurrence of undernutrition with overweight, obesity, or other diet-related noncommunicable diseases. In an increasingly connected global food system, multinational and domestic food industry actors - through their commercial practices and corporate political activity - both contribute to the double burden of malnutrition and hold potential to addr…
Drivers and levers of the double burden of malnutrition in Cape Town, South Africa
South Africa faces a high burden of malnutrition, including undernutrition, overweight, obesity, and diet-related non-communicable diseases. This coexistence and interaction of multiple forms of malnutrition within individuals and communities across the life-course is referred to as the double burden of malnutrition (DBM) and has complex, interrelated causes that need to be concurrently addressed. This qualitative study explored the drivers and p…

The findings underscore the need for policy interventions and community awareness programs to address and regulate the advertising environment around schools, promoting healthier food and…
Health systems performance for hypertension control using a cascade of care approach in South Africa, 2011–2017
Hypertension is a major contributor to global morbidity and mortality. In South Africa, the government has employed a whole systems approach to address the growing burden of non-communicable diseases. We used a novel incident care cascade approach to measure changes in the South African health system’s ability to manage hypertension between 2011 and 2017. We used data from Waves 1–5 of the National Income Dynamics Study (NIDS) to estimate trends …
Nutrition policy reforms to address the double burden of malnutrition in Zambia
The evolution of nutrition patterns in Zambia has resulted in the coexistence of undernutrition and overnutrition in the same population, the double burden of malnutrition. While Zambia has strong policies addressing undernutrition and stunting, these do not adequately address food environment drivers of the double burden of malnutrition and the adolescent age group and hence the need for nutrition policy reforms. We conducted a theory-based qual…
Self-Management of Diabetes and Associated Factors among Patients Seeking Chronic Care in Tshwane, South Africa
The burden of diabetes continues to increase in South Africa and a significant number of diabetes patients present at public primary healthcare facilities with uncontrolled glucose.

Meals on Wheels
Food insecurity (FI) prevails in Sub-Saharan Africa. Yet, in South Africa, although many people, including the elderly, are vulnerable to FI, little is known about the experiences of older persons (OPs) with FI and the interventions thereof. In South Africa, Meals on Wheels Community Service (MOWCS) provides readymade home meal deliveries for OPs through 209 branches across the country. Therefore, this study investigated MOWCS' role in the promot…

Association between Macronutrient and Fatty Acid Consumption and Metabolic Syndrome
We aimed to examine the association between macronutrient and fatty acid intake and metabolic syndrome (MetS) and its components in South African male mini-bus taxi drivers. One hundred and eighty-five ( n = 185) male taxi drivers, aged 20 years and older, who operate in the Cape Town metropole, South Africa, were included. The International Diabetes Federation (IDF) algorithm was used to define MetS. The association between macronutrient and fat…
Comparison of the Ability of Anthropometric Indices to Predict the Risk of Diabetes Mellitus in South African Males
This study aimed to assess the sensitivity of body mass index (BMI) to predict the risk of diabetes mellitus (DM) and whether waist circumference (WC), waist-to-hip (WHR) and waist-to-height (WHtR) ratios are better predictors of the risk of DM than BMI in South African men aged 20 years and older. Data from the first South African National Health and Nutrition Examination Survey (SANHANES-1) were used. Overall, 1405 men who had valid HbA1c outco…
School Food Environment in Urban Zambia

Nurturing children's development through healthy eating and active living
Fostering the growth, development, health, and wellbeing of children is a global priority. The early childhood period presents a critical window to influence lifelong trajectories, however urgent multisectoral action is needed to ensure that families are adequately supported to nurture their children's growth and development. With a shared vision to give every child the best start in life, thus helping them reach their full developmental potentia…
Exposure of Children to Unhealthy Food and Beverage Advertisements in South Africa
Television (TV) is a powerful medium for marketing food and beverages. Food and beverage marketers tend to use this medium to target children with the hope that children will in turn influence their families' food choices. No study has assessed the compliance of TV marketers with the South African Marketing to Children pledge since the enactment of the 2014 food advertising recommendations by the South African Department of Health and the Adverti…
Exploring Factors Associated with Diabetic Retinopathy Treatment Compliance Behaviour in Cape Town, South Africa
Complete patient adherence to treatment for diabetic retinopathy (DR) is critical to limit vision loss. There is a dearth of evidence regarding the reasons why South African patients referred for suspected vision-threatening DR stay compliant to or default their treatment. The current study sought to explore factors associated with treatment compliance among patients living with diabetes who have been referred for suspected vision-threatening DR …
Body Image and the Double Burden of Nutrition among South Africans from Diverse Sociodemographic Backgrounds

Diet and mortality rates in Sub-Saharan Africa
Countries in SSA are clearly undergoing a nutrition transition. More than half of them are still in the early stage, while a few have reached a point where changes in dietary patterns are affecting health outcomes in a large portion of the population. Those in the early stage of the transition are especially important, since primordial prevention can still be introduced
Intra-familial and ethnic effects on attitudinal and perceptual body image
Resemblances exist between pre-adolescent girls and their mothers on issues related to ideal and attitudinal body image. In this regard, South African researchers should consider the effects ethnicity and family status on body image of women when developing targeted interventions to prevent or manage obesity
