Wilson and colleagues compared the blood pressure response to low (50
mEq/day) vs high (150 mEq/day)
supplemental sodium diets in black vs. female adolescents (ages 13-16).
Urine sodium excretions on
both dietary sodium levels were similar in the boys and girls. Based on the
blood pressure response
to high or low sodium diets, the subjects were classified as salt-sensitive
or resistant. When BP
response to the low sodium diet was the criterion of salt sensitivity, 18% of
the males and 25% of
the females were judged to be salt sensitive. However, when BP response to a
high sodium diet was
used, 30% of the boys vs. 25% of the girls fulfilled the criteria of salt-
sensitivity.
These data suggest that the dietary protocol used may alter the identified
prevalence of salt
sensitivity, particularly in the black male adolescent population.
