Current Projects

Historical perspective

The Non-Communicable Diseases Research Unit (NCDRU) was formed in 2013 during the revitalization of the South African Medical Research Council. The unit was established by merging three existing units which were previously conducting research in different areas of non-communicable diseases (NCDs), and by attracting additional staff from other units affected by the revitalization process. The three units merged to form the NCDRU were:

  1. The Chronic Diseases of Lifestyle Research Unit (CDL)
  2. The Diabetes Discovery Platform (DDP)
  3. The National Collaborative Research Programme on Cardiovascular and Metabolic Diseases (NCRP CV&MD)
NCDRU led projects

2. The South African Diabetes Prevention Programme (SA-DPP) The overall purpose of this project to develop and evaluate a culturally-relevant model of diabetes prevention programme for South Africa, using evidence from successful diabetes prevention effectiveness and implementation programmes. Our expectations are to arrive at a model that will inform lifestyle interventions to prevent diabetes and other lifestyles related conditions at primary health care level in South Africa, and serves as a prototype for adaptation in other countries in the region that are confronted to similar challenges like South Africa.

10. Identification of metabolic pathways that predict type 2 diabetes in black South African women. This study aims to identify metabolites and/or metabolic pathways that predict progression to impaired glucose tolerance and type 2 diabetes in black South African women, and to determine whether these metabolites/metabolic pathways are modified by lifestyle factors, including diet, physical activity and socioeconomic status. Funding: Swedish Development Grant, in collaboration with Prof Tommy Olsson, University of Umeå, Sweden. Julia Goedecke Amy Mendham
11. Determinants of type 2 diabetes risk in middle-aged black South African men and women: dissecting the roles of sex hormones, inflammation and glucocorticoids. The study aims to examine the changes in sex hormone levels over the menopausal transition in women, and in men of the same age, and explore the effects on body fat distribution and insulin sensitivity and secretion, dissecting the specific roles of glucocorticoids and inflammatory mediators, in the context of HIV.

12. Essential fatty acid status of pre-school children and women with distinct eating patterns in South Africa Investigating the essential fatty acid status of (i) pre-school children in relation to lipid profile, anthropometry and dietary intake, and (ii) women in relation to lipid profile, waist:height ratio, obesity and dietary intake in four geographical areas (2 urban, 2 rural) with distinct eating patterns in South Africa. Paul van Jaarsveld Lize van Stuijvenberg

13. An epidemiological study on the anthropometric status and liver intake (an exceptionally rich source of preformed vitamin A) in under-5 children in the Northern Cape province. The aim is  (i) to  identify pockets where the prevalence of stunting is high, and (ii)  to establish how widespread liver consumption (and hence vitamin A intake from liver) in the young children of this province is. Lize van Stuijvenberg  
14. Total body vitamin A pool size in preschool children before and after vitamin A supplementation in an impoverished South African community where liver is frequently eaten and children exposed to vitamin A fortified staple foods. This study is part of a multi-country regional study, coordinated by the IAEA, which aims to assess total body vitamin A (as measured by stable isotope dilution), as well as risk of toxicity, in populations exposed to multiple vitamin A interventions. Lize van Stuijvenberg  
15. Cardiovascular Risk in Black South Africans (CRIBSA) Study This study, which previously examined the prevalence of cardiovascular disease (CVD) risk factors in the black population of Cape Town, now aims to determine the biochemical and genetic markers, genes and level of renal impairment associated with these CVD risk factors.

6. The effects of an aspalathin-enriched unfermented rooibos extract on cardio-metabolic risk factors in obese black South African women. The primary aim of the study is to identify indigenous plants endemic to the Northern KwaZulu Natal area, and produce standardized bioactive extracts or fractions with health properties that have been shown to be effective at preventing or ameliorating metabolic conditions related to IR and T2D. The secondary aim is to compare the efficacy of the most effective extract(s) produced to an aspalathin-enriched rooibos extract, which will be the benchmark in terms of bioactivity. A tertiary aim will be to understand the mechanism of action of the effective extract and ensure its effectiveness and safety using cell and animal models and finally to test the efficacy of the selected extract in an obese black African women.
