Background: Excess sodium consumption has strong links with hypertension and cardiovascular disease with FDA calling to limit sodium intake. However, little is known regarding the trends of actual sodium intake among hypertensive patients in the United States.
Methods: Data from The National Health and Nutrition Examination Survey (1999-2012), was used to identify adults with self-reported hypertension. Sodium intake was measured through 24-hour dietary recall. Linear regression was used to assess the time trends of sodium intake.
Results: Between 1999 and 2012, sodium consumption increased 14.2% among all adults with hypertension (P=0.01). This was true for males (13.3%, P=0.02) and females (12.1%, P=0.02). A trend for increased sodium consumption was noted for Hispanic (26.2%, P=0.02) and African-American (20%, P=0.03) patients, but not among non-Hispanic Whites (P=0.1) (fig 1). Daily sodium consumption was lower among patients taking antihypertensive medications (3.2±1.6g vs. 3.5±2.0g) and those with a history of myocardial infarction (3.0±1.7g vs. 3.4±1.7g), heart failure (3.0±1.8g vs. 3.4±1.7g), diabetes mellitus (3.2±1.6g vs. 3.4±1.8g) or stroke (3.0±1.4g vs. 3.4±1.8g) (all p <0.001).
Conclusions: In the past two decades, sodium intake has increased among individuals with hypertension, especially among minority populations. Improved population-based interventions to reduce the sodium consumption among hypertensive adults are needed.
