Abstract

The authors estimated the prevalence of taking action to reduce intake related to actual sodium consumption among 2970 nonpregnant US adults 18 years and older with self-reported hypertension by using data from the National Health and Nutrition Examination Survey 1999-2004. Adjusted multiple linear regression assessed differences in mean sodium intake by action status. A total of 60.5% of hypertensive adults received advice to reduce sodium intake. Of this group, 83.7% took action to reduce sodium. Action to reduce sodium intake differed significantly by age, race/ethnicity, and use of an antihypertensive. The mean (±standard error) sodium intake among hypertensive adults was 3341±37 mg and differed by sex, age, race/ethnicity, education, and body mass index (P<.05), with the lowest intake among adults aged 65 years and older (2780±48 mg). Mean intake did not differ significantly by action status either overall or by subgroup except for one age category: among patients 65 years and older, mean intake was significantly lower among those who took action (2715±63 mg) than among those who did not (3401±206 mg; P=.0124). Regardless of action, mean intake was well above 1999-2004 recommendations for daily sodium intake and about twice as high as the current recommendation for hypertensive adults (1500 mg).
