To support strategies to reduce dietary sodium intake, 2013 Behavioral Risk Factor Surveillance System (BRFSS) data from states and territories that implemented the new sodium-related behavior module were assessed. A total of 180,067 were included in the study; participants answered questions from the optional sodium-related behavior module. The proportion of respondents who reported taking action to reduce sodium intake ranged from 38.7% (Utah) to 73.4% (Puerto Rico), with a median of 50.6%. Across all participating locations, a higher proportion of participants with hypertension reported taking action to reduce sodium intake compared with those without hypertension (p<0.001 for all comparisons).

The proportion of participants who reported receiving advice from a healthcare professional to reduce sodium intake ranged from 13.5% (Minnesota) to 41.4% (Puerto Rico), with a median of 21.1%. Across all locations, a higher proportion of participants with hypertension reported receiving health professional advice to reduce sodium intake compared with those without hypertension (p<0.001 for all comparisons). Receiving advice from a healthcare practitioner was associated with taking action towards reducing sodium levels (prevalence ratio=1.59).
