Dietary Sodium Intake and Sodium Density in the United States: Estimates From NHANES 2005–2006 and 2015–2016

BACKGROUND In the United States, current guidelines recommend a total sodium intake METHODS In the National Health and Nutrition Examination Survey (NHANES), we estimated the prevalence of adherence to sodium intake recommendations ( RESULTS In 2005–2006, 23.1% (95% confidence interval [CI]: 21.5, 24.9) of the US population consumed CONCLUSIONS Adherence estimated by sodium density is substantially less than adherence estimated by total sodium intake, especially among persons with lower kilocalorie intake. Further efforts to achieve population-wide reduction in sodium density intake are urgently needed.
