Changes in Diet Quality over 10 Years Are Associated with Baseline Sociodemographic and Lifestyle Factors in the Multiethnic Cohort Study.

ABSTRACT:

Background

Trends in diet quality among US adults indicate a steady improvement, but data on longitudinal individual-level changes in diet quality are still limited.

Overall diet quality was measured by use of the Healthy Eating Index-2015 (HEI-2
