Age-standardized weighted mean (95% CI) consumed sodium, kilocalories, and sodium density in the US population in 2005–2006 in NHANES, with prevalence of the population adhering to a recommended sodium intake of <2,300 mg/day and a recommended sodium density of <1.1 mg/kcal (or 2,300 mg/2,100 kcal)a

aData are presented as mean (95% CI) or proportion (95% CI).
bVariance could not be estimated due to few numbers across strata, so variance was estimated using the average of the variances from the strata with multiple sampling units for each stratum with 1 sampling unit.
cNon-Hispanic Asian was not assessed by NHANES in 2005–2006.
