The Massachusetts Blood Pressure Study, Part 2. Modestly elevated levels of sodium in drinking water and blood pressure levels in high school students.
The blood pressure (BP) of tenth grade students from a town with 42 mg Na/L in drinking water was compared to that of comparable tenth grade students in a geographically contiguous community with 6 mg Na/L. No statistically significant difference occurred in mean BP between the two communities for males and females for diastolic BP and male systolic BP. However, the low sodium community females displayed a significantly higher BP (p less than 0.05) of 1.6 mmHg. Analysis of covariance for potentially confounding variables did not significantly alter the initial findings. In summary, an average of 36 mg Na/L higher Na levels in the drinking water was not associated with an increase in BP levels in tenth grade students.
