Changes in dietary intakes and cardiovascular disease risk factors in black South Africans from 2005 to 2015 : the PURE-SA-NW study
type: CreativeWork
description: Background: The diets of populations are constantly changing, and the South African population is no exception. Over the last couple of decades, the diets of rural and urban South Africans have been undergoing a rapid nutrition transition, changing from prudent traditional diets that have been typically low in fat and energy, to Westernised diets containing foods high in fat and energy. This shift in dietary patterns and nutrient intakes is referred to as the nutrition transition. Dietary changes associated with a nutrition transition are linked to an increase in non-communicable diseases (NCDs) globally, but also in South Africa in particular. The World Health Organisation (WHO) has identified NCDs as the leading cause of death worldwide. The 2018 NCD report of the WHO revealed that the majority (19%) of NCD deaths in South Africa could be attributed to cardiovascular disease (CVD). The emergence of cardiovascular diseases (CVDs) has been linked to several preventable risk factors, including hypertension, overweight, obesity, diabetes and high cholesterol levels. Lowering the prevalence of these preventable risk factors would be key to addressing the ongoing public health dilemma. Research evidence has shown that dietary and nutrient intake is associated with CVD risk. A growing body of evidence also suggests that the type of dietary fat rather than the total amount of dietary fat consumed drives CVD risk. The primary aim of this thesis is to examine the changes in dietary intake from 2005 to 2015, as well as the associations between the changes in dietary fat intake and the changes in CVD risk from 2005 to 2010, of rural and urban South African groups amid a nutrition transition. Methods: This study is a sub-study of the South African leg in the North-West province of the multinational Prospective Urban and Rural Epidemiological (PURE) study (PURE-SA-NWP). Data for PURE-SA-NWP were collected from two communities, one urban and one rural. Baseline data were collect…
