Abstract
Background
Globally hypertension is stabilising, but in sub-Saharan Africa the incidence
of hypertension remains on an increase. Although this might be attributed to
poor healthcare and ineffective antihypertensive treatment, there is a
limited understanding of population and individual-specific cardiovascular
pathophysiology – necessary for effective prevention and treatment
strategies in Africa. As there is a lack of longitudinal studies tracking
the early pathophysiological development of hypertension in black
populations, the African-PREDICT study was initiated. The purpose of this
paper is to describe the detailed methodology and baseline cohort profile of
the study.
Methods and results
From 2013 to 2017, the study included 1202 black (N = 606)
and white (N = 596) men and women (aged 20–30 years) from
South Africa – screened to be healthy and clinic normotensive. At baseline,
and each 5-year follow-up examination, detailed measures of health
behaviours, cardiovascular profile and organ damage are taken. Also,
comprehensive biological sampling for the ‘omics’ and biomarkers is
performed. Overall, the baseline black and white cohort presented with
similar ages, clinic and 24-hour blood pressures, but black adults had lower
socioeconomic status and higher central systolic blood pressure than white
individuals.
Conclusions
The prospective African-PREDICT study in young black and white adults will
contribute to a clear understanding of early cardiovascular disease
development.
