The association between seven-day objectively measured habitual physical activity and 24 h ambulatory blood pressure: the SABPA study
Hamer, M.; Bruwer, E.J.; De Ridder, J.H.; Swanepoel, M.; Cockeran, M.; Malan, L. (Springer Nature, 2017)Few studies have examined objective physical activity in relation to 24 h ambulatory blood pressure (BP). We aimed to assess the association of 7-day objectively measured habitual physical activity with ambulatory BP in a ... -
Association of waist circumference with perception of own health in urban African males and females: the Sympathetic Activity and Ambulatory Blood Pressure in Africans (SABPA) study
Botha, J.; Malan, L.; Potgieter, J.C.; Steyn, H.S.; De Ridder, J.H. (Health & Medical Publishing Group (JEMDSA), 2012)Background: Current waist circumference (WC) cut-points of the Joint Statement Consensus (JSC) (male ≥ 94 cm, female ≥ 80 cm) were compared with a recently proposed WC cut-point (RPWC) (male ≥ 90 cm, female ≥ 98 cm). In ... -
Determining the waist circumference cut off which best predicts the metabolic syndrome components in urban Africans: the SABPA study
Prinsloo, J.; Malan, L.; De Ridder, J.H.; Potgieter, J.C.; Steyn, H.S. (Thieme Publishing, 2011)Various studies have shown that the relationship between waist circumference (WC) and abdominal obesity is age, gender as well as ethnicity-dependent. WC criteria for Sub Saharan Africans have not been defined by the ... -

The effect of a 12-week resistance training programme on the body composition and resting metabolic rate in a cohort of caucasian and coloured, premenopausal women aged 25-35 years
Swanepoel, Mariëtte; De Ridder, J. Hans; Wilders, Cilas J.; Van Rooyen, Johannes; Strydom, Gert L.; Ellis, Suria (AFAHPER-SD, 2013)Resting metabolic rate (RMR) is the largest component of daily energy expenditure, with lower values in the black population. Resistance training is considered to be the most effective exercise modality to increase fat-free ... -
Liggaamsamestelling en rustende metaboliese tempo (RMT) in 25 tot 35 jarige vroue van gemengde herkoms en Kaukasiër vroue : 'n profielontleding
Swanepoel, Mariëtte; De Ridder, J. Hans; Wilders, Cilas J.; Van Rooyen, Johannes; Strydom, Gert L.; Ellis, Suria (University of Stellenbosch, 2013)Obesity is a rapid growing epidemic worldwide, affecting more women, especially black and coloured women (women of mixed ancestry) in South Africa. Limited research regarding the body composition and resting metabolic rate ... -
Structural vascular disease in Africans: performance of ethnic-specific waist circumference cut points using logistic regression and neural network analyses: the SABPA study
Botha, J.; De Ridder, J.H.; Potgieter, J.C.; Steyn, H.S.; Malan, L. (George Thieme Verlag, 2013)A recently proposed model for waist circumference cut points (RPWC), driven by increased blood pressure, was demonstrated in an African population. We therefore aimed to validate the RPWC by comparing the RPWC and the Joint ...
