Defensive coping, urbanization, and neuroendocrine function in Black Africans: the THUSA study
Dissociation between b-adrenergic behavioral and physiological defensive active coping (AC) responses was associated with cardiometabolic risk in urban but not rural African males. Whether this is partly driven by underlying ...
Differences in MetS marker prevalence between black African and Caucasian teachers from the North West Province: Sympathetic activity and ambulatory blood pressure in Africans (SABPA) study
Background: The aim of this study was to compare metabolic syndrome (MetS) prevalence between black and Caucasian Africans using different definitions, and secondly, to determine the association between MetS, anthropometric ...
Prognostic significance of dipping in older hypertensive patients
(Taylor & Francis, 2015)
Background and aims. Arterial hypertension doubles the risk of coronary heart disease, heart and kidney failure, and peripheral arterial disease. Less variation in diurnal ambulatory blood pressure monitoring (ABPM) patterns ...
Cardiovascular function and psychological distress in urbanised black South African : The SABPA study
(Clinics cardiv publishing, 2010)
Sex hormones associated with subclinical kidney damage and atherosclerosis in South African men: the SABPA study
Background: Hypertension and increased blood glucose are associated with subclinical kidney damage, atherosclerosis and with low testosterone values. Low testosterone in men is often accompanied by increased levels of ...
A significant decline in IGF-I may predispose young Africans to subsequent cardiometabolic vulnerability
(Oxford Univ Press, 2010)
Objectives: Low serum IGF-I is an independent risk factor for diabetes and cardiovascular disease. These noncommunicable diseases are extremely common in urban black South Africans, but their IGF-I concentration is unknown. ...
QTc prolongation, increased NT-proBNP and pre-clinical myocardial wall remodeling in excessive alcohol consumers: the SABPA study
Alcohol contributes greatly to vascular and structural modifications. Due to differences in the metabolism and tolerance of alcohol between ethnic groups, the manner of these modifications may differ. We investigated the ...
Serum calcium revisited: associations with 24-h ambulatory blood pressure and cardiovascular reactivity in Africans
Sub-Saharan Africans face an increasing burden of hypertension. Although controversial, recent experimental evidence strongly suggests that serum calcium contributes to elevated blood pressure through increased vascular ...
Testosterone and acute stress are associated with fibrinogen and Von Willebrand factor in African men: the SABPA study
Background: Low testosterone, acute and chronic stress and hypercoagulation are all associated with hypertension and hypertension-related diseases. The interaction between these factors and future risk for coronary ...
The usefulness of Y-glutamyltransferase as a marker of cardiovascular function in Africans and caucasians: the SABPA study
(Informa HealthcareTaylor & Francis, 2012)
Aim. Serum γ-glutamyltransferase (GGT) is increasingly regarded as a marker of vascular function. However, the usefulness of this marker is in dispute. Gender and ethnic differences, as well as the serum level range where ...
