Technical Abstract: The aim of this study was to examine the association of snacking with diet quality in adolescents aged 12-18 years (n = 5,811). Snacks/drinks were combined when eating occasions were named in the 24-h recall, but analysis separated snacks from snacks/drinks that were only drinks. Adolescents were classified by frequency of snack consumption (0, 1, 2, 3, 4+ snacks per day), and by % of daily energy intake obtained from snacks (0, <10, 10-19, 20-29, 30-39, 40% or more). Diet quality was assessed using the Healthy Eating Index (HEI-2005) with component scores determined by dietary intakes of macronutrients, sodium, and MyPyramid food groups per 1,000 calories. Energy intake increased, but energy-adjusted intakes of total fat did not differ, carbohydrate was positively associated, and sodium was inversely associated with snacking frequency and percentage of energy from snacks. HEI-2005 components improved with snacking included total and whole fruit, total and whole grain, healthy oils, and sodium; the solid fat, alcohol, added sugars score did not differ, but the meat & beans score was decreased with snacking frequency and with intake of calories from snacks. Snackers eating 2+ snacks per day, and snackers having <40% energy from snacks had higher total HEI-2005 scores than non-snackers. Snacking in moderation is associated with improved diet quality among adolescents in the U.S.
