To the Editor: Dr Whelton and colleagues1 did not accurately address the role of dietary
sodium reduction in the primary prevention of hypertension. They summarized
the findings of the TONE trial2 and the
DASH-Sodium trial,3 but neither of these
can be considered as primary preventive interventions. Participants in these
trials had treated hypertension or fulfilled, in most instances, the Joint
National Committee VI criteria for blood pressure–lowering treatment.4 Similarly, their description of observational studies
(NHANES I Epidemiologic Follow-up Study and Finnish Study), which demonstrated
an association between dietary sodium intake and mortality independent of
blood pressure, do not seem relevant.
