A previous study by the current authors demonstrated a statistically significant and clinically important elevation of 3-5 mmHg in mean systolic and diastolic blood pressure in high school sophomores in a community with 108 mg/L of sodium in the water supply when compared to their peers in an appropriately matched community with 8 mg/L of sodium. The current investigation, employing identical techniques but studying third graders in the same two communities, showed similar results. This second look considered dietary intake and urinary excretion of sodium. Since the difference in 24-hour dietary sodium consumption was 300 milligrams between the communities, an intake of one liter of high sodium tap water represented approximately 25 per cent of the difference in total sodium intake between the two communities. These studies suggest that sodium consumption in both drinking water and diet may be contributing to the difference in blood pressure distributions among the normotensive children in the two communities.
