Are behavioural risk factors to be blamed for the conversion from optimal blood pressure to hypertensive status in Black South Africans? A 5-year prospective study
Key result
Modifiable risk factors including smoking, waist circumference, and alcohol intake significantly predicted the development of hypertension in 24% of Black South Africans with optimal baseline BP.
Why the study?
Do modifiable behavioral risk factors predict the 5-year development of hypertension in Black South Africans with optimal baseline blood pressure?
Population
478 African volunteers aged > 30 years with optimal blood pressure at baseline, from a sample of 6000…

Do modifiable behavioral risk factors predict the 5-year development of hypertension in Black South Africans with optimal baseline blood pressure?
P
Population
478 African volunteers aged > 30 years with optimal blood pressure (≤ 120/80 mm Hg) at baseline, from a sample of 6000 randomly selected households in rural and urban areas of North West Province, South Africa.
I
Intervention
Modifiable behavioral risk factors (smoking, alcohol intake, waist circumference, γ-glutamyltransferase)
O
Outcome
Development of hypertension (≥ 140/90 mmHg) and 5-year change in blood pressuresurrogate
Modifiable lifestyle factors, including alcohol intake (indicated by γ-glutamyltransferase) and central obesity, are significant drivers of the rapid conversion from optimal blood pressure to hypertension in Black South Africans.
Cite This Study
Schutte et al. (2012) conducted a cohort in optimal blood pressure (n=1,994). Modifiable risk factors (smoking, waist circumference, alcohol intake) was evaluated on development of hypertension. Modifiable risk factors including smoking, waist circumference, and alcohol intake significantly predicted the development of hypertension in 24% of Black South Africans with optimal baseline BP.
