Evidence for an Increased Intake of Sodium in Hypertension Based on Urinary Excretion of Sodium. ∗ †

Conclusion

Among 28 subjects with and without hypertension, the group with high blood pressure had significantly greater (p<.01) sodium intakes (as measured by urinary outputs) than did the group of non-hypertensives. This finding was in agreement with a hypothesis previously proposed, namely, that the level of sodium intake was of primary etiologic importance in the development of essential hypertension.
