Racial differences in blood pressure: genetic and environmental factors
  1. P. S. Sever


    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.
