Abstract 12478: Evaluating Sodium and Saturated Fat Intake Patterns to Identify Likely Change in Guideline Compliance
Background: Altering sodium and saturated fat intake at a population level is integral for achieving cardiovascular health, but compliance with recommended dietary guidelines within the population is low. Evaluating population intake data and dietary patterns could provide useful information for developing targeted behavior change strategies. As such, within a US-population based cohort we sought to evaluate compliance to sodium and saturated fat guidelines and overall intake patterns to identify potential avenues for triggering sustainable behaviour change.
Methods & Results: Analyses were based on the NHANES 2005-2006 data (n = 2451) and daily sodium and saturated fat intake were extracted from the dietary interview data. Dietary guidelines were drawn from the American Heart Association 2020 impact goals. Intake analyses demonstrated that 7% of the population were compliant with the sodium guidelines (<1500mg per day) and 11% were compliant with the saturated fat recommendations (<7% of total energy intake). Pattern analyses showed that for sodium 54 people were within 10% of these guidelines and 166 were within 20%. For saturated fat the potential benefit of change was larger, with 131 people being within 10% of the guidelines and 340 being within 20% of the guidelines. The findings highlight that a 20% reduction in sodium and saturated fat at the population-based level would provide a net reclassification from exceeding guidelines to complying with guidelines of 6% and 14% respectively.
Conclusions: Evaluating the population intake data highlighted that whilst the majority of the population does not reach sodium and saturated fat guidelines, a noteworthy proportion of the population are within a reasonable range. Change analyses showed that small changes of 10 or 20% could convey useful benefits at the population-based level. As such, it would be beneficial for future cardiovascular prevention efforts to focus on achieving small dietary changes in individual within reach of the guidelines, rather than solely the failure of the majority of the population to be guideline compliant. An exploration of various methods is provided and examples of how this could be achieved are discussed.
