Associations between dietary salt, potassium and blood pressure in South African adults: WHO SAGE Wave 2 Salt & Tobacco
(Elsevier, 2017)Background & aims In June 2016, South Africa implemented legislation mandating maximum sodium levels in a range of processed foods with a goal of reducing population salt intake and disease burden from hypertension. Our ... -
A comparison of the cardiometabolic profile of black South Africans with suspected non-alcoholic fatty liver disease (NAFLD) and excessive alcohol use
(Elsevier, 2015)Excessive alcohol use and non–alcoholic fatty liver disease (NAFLD) are putative cardiovascular disease risk factors. In order to ease the identification of these conditions on primary health care level, we aimed to determine ... -
The contribution of the C-824T tyrosine hydroxylase polymorphism to the prevalence of hypertension in a South African cohort: the SABPA study
(Taylor & Francis, 2013)The C-824T single nucleotide polymorphism in the promoter region of the tyrosine hydroxylase gene has been associated with hypertension. It is well documented that African South Africans exhibit a higher prevalence of ... -
Cultural coping as a risk for depression and hypertension: the SABPA prospective study
(Clinics Cardive, 2018)Objectives: In past studies, a lack of social support has been associated with cardiovascular disease (CVD) risk, particularly in black Africans. However, whether or not coping strategies have beneficial effects on blood ... -
Defensive coping facilitated a smaller cortisol-to-estradiol ratio and a higher hypertension risk: the SABPA study
(Taylor & Francis, 2018)Objectives: Taxing psychosocial stress and defensive coping have been associated with hypoactivity in cortisol, a vasoconstrictive agent. Estradiol has vasodilatory properties with cardio- and neuroprotective effects. It ... -
Effects of Montmorency tart cherry (Prunus Cerasus L.) consumption on vascular function in men with early hypertension
(Amer Soc Nutrition, 2016)Background: Tart cherries contain numerous polyphenolic compounds that could potentially improve endothelial function and reduce cardiovascular disease risk. Objective: We sought to examine the acute effects of ... -
Longitudinal changes of cardiac troponin and inflammation reflect progressive myocyte stretch and likelihood for hypertension in a Black male cohort: the SABPA study
(Springer, 2019)Inflammation was cross-sectionally associated with subclinical wall remodeling and hypertension. Whether longitudinal changes (∆) in inflammation, myocyte injury (troponin T), and stretch (N-terminal-pro-B-type natriuretic ... -
The protective role of oestradiol against silent myocardial ischemia and hypertension risk in South African men: the SABPA study
(Elsevier, 2017)Background Oestradiol has a protective effect on coronary artery health in women but the effect it has on men, is controversial. A translational approach was followed to assess whether sex hormone levels are associated ... -
Self-reported alcohol intake is a better estimate of 5-year change in blood pressure than biochemical markers in low resource settings: the PURE study
(Wolters Kluwer, 2014)Background: Despite criticism of self-reported alcohol intake, it is a valuable tool to screen for alcohol abuse as a risk factor for cardiovascular disease. We aimed to compare various self-reported estimates of alcohol ... -
Sodium and potassium intake in South Africa: an evaluation of 24-hour urine collections in a white, black, and Indian population
(Elsevier, 2016)Limited number of studies on salt intake has been conducted in the South Africa. The present study established the sodium and potassium excretion (24-hour urine collection) of three different South African populations. In ...
