Abstract

Objective: The purpose of this article is to examine sociodemographic and health behavior factors associated with dietary intake as measured by the healthy eating index (HEI-2010) for persons with and without diabetes (T2D). Design: A secondary data analysis of three NHANES data cycles spanning 2007-2012. Multiple linear regression assessed racial/ ethnic differences in HEI-2010 scores in those without T2D, with T2D, and with undiagnosed T2D. Participants: The sample included nonpregnant adults aged ≥20 years who had two days of reliable dietary recall data. Outcome Measures: Total scores for the HEI-2010. Results: For those without T2D, there was a significant association between race/ ethnicity and HEI score, with non-Hispanic Blacks achieving significantly lower scores than their non-Hispanic White counterparts. Differences in HEI-2010 score were also associated with age, sex, smoking status and time spent in the United States. Racial/ ethnic differences in dietary patterns were present, but not significant in those with undiagnosed or diagnosed T2D. Conclusions: Racial/ethnic disparities in dietary patterns are present in individuals without T2D, but differences are not statistically significant in those with undiagnosed or diagnosed T2D. Non-Hispanic Blacks without T2D received significantly lower HEI-2010 scores than non-Hispanic Whites. Further research is necessary to determine whether or not similarities in dietary intake across racial/ethnic groups with T2D will be reflected in diabetes-related health outcomes in this population.
