To determine the dietary patterns typically consumed by urban African American and White population and their association of the diet quality of these patterns with 2013 ACC/AHA 10-year risk for atherosclerotic cardiovascular disease (ASCVD).
Subjects were persons who completed two 24-hour dietary recalls during the follow-up wave of the Healthy Aging in Neighborhoods of Diversity across the Life Span study, 2009-2013. Of the 2140 persons with two recalls, 1358 had sufficient data to calculate the 10-year ASCVD risk score. Hierarchical case clustering was used to generate 4 dietary patterns (DPs) based on food group energy contribution. The Healthy Eating Index (HEI)-2010 was used to evaluate diet quality. The four DPs were then used as a grouping factor in linear regression, adjusting for sex, race and income with Tukey HSD multiple comparisons used for post hoc comparison of diet quality and ASCVD risk score means.
All the patterns had sandwiches as the first or second food group contributing the majority of daily energy (10.30-16.06%). The pattern with the highest HEI-2010 score included sandwiches (10.12% of energy) along with vegetables (9.87%) and cheese/yogurt (4.99%). Persons consuming this pattern had significantly lower 10-year ASCVD risk (6.3±0.8) compared to the meats/sandwiches DP (9.6±0.9) and sandwiches/bakery products DP (9.2±0.4)(p=0.0208 and p=0.0031, respectively).
HEI-2010 scores indicated improvements in diet quality were warranted to achieve a healthful diet. The findings provided evidence that variations of the Western dietary pattern were associated with different ASCVD 10-year risks.
