摘要
A blood pressure survey was performed in isolated Pygmy communities and Bantu population samples living either in close relationship with the Pygmies or in separate areas within the same region. The Pygmies are still living as hunter-gatherers, whereas the Bantus rely on agriculture for food provision. Mean blood pressures in Pygmies were 130/85 mm Hg in males and 126/80 mm Hg in females and in Bantus were 137/87 mm Hg in males and 136/84 mm Hg in females. In spat urine the mean urinary sodium concentration was higher in Bantus than Pygmies (86 versus 37 mmol/L in malts; 95 versus 56 mmol/L in females). In the total population urinary potassium concentration was very high (150 mmol/L), calcium concentration very low (0.4 mmol/L), and urea concentration low (6.9 g/L). After adjustment for age, height, weight, and sex, no racial differences in blood pressure were present. Blood pressure increased with age but body mass index did not. Diastolic pressure correlated significantly but negatively with urinary sodium in multiple regression analysis. Our study demonstrates that blood pressure increases with age in hunter-gatherer populations on a low to moderately high sodium diet in the presence of a low urinary excretion of calcium coupled with a low protein intake.
