The adolescent obesity rate in the United States has nearly doubled over the past 3 decades. Currently, 20.6% of adolescents are affected by obesity (1). The primary cause of obesity is consuming more energy than one expends. For that reason, researchers seek to identify factors that are related to higher energy intakes. A recent German study found that, among adolescents, eating late in the day was associated with a higher total daily energy intake (2). However, information about consumption during this time of day by U.S. youth is lacking. This data brief characterizes food/beverage consumption by individuals age 12 to 19 years in the U.S. population during the late evening (from 8:00 pm through 11:59 pm; see “Definitions” on page 9) and identifies associations with energy and nutrient intake. This analysis is based on one day of dietary intake data from What We Eat in America (WWEIA), National Health and Nutrition Examination Survey (NHANES) 2013-2016.
