Key result
Racial and environmental factors influence blood pressure levels, with blacks and whites showing differences in plasma renin activity and plasma noradrenaline concentration.
Why the study?
Do genetic and environmental factors influence blood pressure levels and its biochemical correlates in black and white populations?
Observational
Do genetic and environmental factors influence blood pressure levels and its biochemical correlates in black and white populations?
Genetic and environmental factors both influence blood pressure, with differing pathogenetic mechanisms (renin and noradrenaline) suggested between black and white populations.

Racial BP differences may reflect distinct mechanisms; hypothesis-generating and should not change practice.
Summary The present study shows that different racial groups (black and white) living in a similar environment have different levels of blood pressure. Furthermore the same ethnic group living in a dissimilar environment also has different blood pressure distributions: thus it seems that both genetic (racial) and environmental factors influence the levels of arterial pressure. The data presented also reveal that there are racial differences in certain biochemical correlates of blood pressure, namely plasma renin activity and plasma noradrenaline concentration, and it is suggested that these observations may underline differing pathogenetic mechanisms for blood pressure elevation in blacks and whites.

Peter Sever (1981) conducted an observational in Blood pressure. Race (black vs white) and environmental factors was evaluated on Blood pressure levels and biochemical correlates (plasma renin activity and plasma noradrenaline concentration). Racial and environmental factors influence blood pressure levels, with blacks and whites showing differences in plasma renin activity and plasma noradrenaline concentration.
