Liu J, et al. - This study was intended to characterize the quality of diets among youth in the United States. Between 1999 and 2016, researchers conducted serial cross-sectional investigation utilizing 24-hour dietary recalls from youth aged 2 to 19 years from 9 National Health and Nutrition Examination Survey (NHANES) cycles. A total of 3,1 420 youth aged 2 to 19 years were recruited in this study, the mean age was 10.6 years; 49.1% were female. The primary endpoints included the survey-weighted, energy-adjusted mean consumption of dietary components and proportion meeting targets of the American Heart Association (AHA) 2020 continuous diet score (range, 0-50; based on total fruits and vegetables, whole grains, fish and shellfish, sugar-sweetened beverages, and sodium). According to the serial NHANES surveys from 1999 to 2016, it was noted that the calculated overall diet quality of US youth revealed modest improvement, but more than half of youth still had poor-quality diets.
