Healthy Eating Index-2015 Scores Vary by Types of Food Outlets in the United States.

ABSTRACT: Diet quality in the United States is improving over time but remains poor. Food outlets influence diet quality and represent the environments in which individuals make choices about food purchases and intake. The objective of this study was to use the Healthy Eating Index-2015 (HEI-2015) to evaluate the quality of foods consumed from the four major outlets where food is obtained-stores, full-service restaurants, quick-services restaurants, and schools-and to assess changes over time. This cross-sectional study used 24 h dietary recall data from eight cycles (2003-2004 to 2017-2018) of the National Health and Nutrition Examination Survey (NHANES). Linear trend estimation was used to test for changes in HEI scores over time, and balanced repeated replicate weighted linear regression was used
