Abstract (Summary)

There is a disproportionate burden of low diet quality among young adults compared to other adult sub-populations, but there is limited understanding of this low diet quality and reasons for it. To fill this gap, data from a sample of young adults (N = 1261) from the National Health and Nutrition Examination Survey (NHANES), 2013-2014, were used to explore relationships between self-rated diet quality and objective diet quality, as measured by Healthy Eating Index (HEI) scores. Multiple regression analysis showed that excellent (b = 8.445, p < .001), very good (b = 9.256, p < .001), and good (b = 5.438, p < .001) perceived diet quality are significant predictors of total HEI score compared to the referent category of poor perceived diet quality, but the full model only predicted 16.7% of the variance in total HEI score suggesting other factors may also be at play. Results of the ordered logit showed that whole fruit (OR=1.092, p = .033), whole grains (OR= 1.044, p = .035), and empty calories (OR=1.053, p = .001) have a statistically significant effect on the odds of having a higher rating of perceived diet quality (fair, good, very good, excellent) instead of a poor rating of diet quality, but the increase in odds is low. Overall the findings suggest that there are significant relationships between perceived and objective diet quality, but other variables play a substantial role in explaining these two types of diet quality.
