Analysis of 24-hour urine samples from a large sample of US adults provides important baseline data on estimated sodium and potassium intake, reports a study in The Journal of the American Medical Association.
The cross-sectional study included 24-hour urine collections from 827 men and women aged 20 to 69 years. The subjects were drawn from the examination component of the National Health and Nutrition Examination Survey (NHANES) in 2014. The researchers estimated 24-hour urinary sodium and potassium excretion and their molar ratios.
Nearly two-thirds of the study population were white; Hispanic, black, and Asian racial/ethnic groups were represented
