Table 2.

Estimated mean (SE) usual 24-hour sodium excretion, potassium excretion, and sodium-to-potassium ratio among U.S. adults aged 20–69 years, by hypertension status, NHANES 2014.

Hypertensive
(n=235)		 Pre-hypertensive
(n=183)		 Optimal
(n=348)
Mean SE Mean SE Mean SE
Sodium excretion, mg/d 3739.6 70.0 3553.7 60.1 3657.9 73.3
Potassium excretion, mg/d 1993.7 42.8 2080.6 50.2 2154.2 53.4
Sodium-to-potassium ratio 3.4 0.1 3.2 0.1 3.2 0.1

Least square means of usual excretion were adjusted for mean-centered age, sex, race/ethnicity, and mean-centered BMI. F tests for trend in 24-hour urinary analyte excretion by hypertensive status were not statistically significant. Sodium-to-potassium ratio expressed as molar ratio.
