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 ... -
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 ...
