Purpose: To determine the prevalence and correlates of missing meals among adolescents. Design: The 2010 National Youth Physical Activity and Nutrition Study, a cross-sectional study. Setting: School based. Participants: A nationally representative sample of 11 429 high school students. Measures: Breakfast, lunch, and dinner consumption; demographics; measured and perceived weight status; physical activity and sedentary behaviors; and fruit, vegetable, milk, sugar-sweetened beverage, and fast-food intake. Analysis: Prevalence estimates for missing breakfast, lunch, or dinner on ≥1 day during the past 7 days were calculated. Associations between demographics and missing meals were tested. Associations of lifestyle and dietary behaviors with missing meals were examined using logistic regression controlling for sex, race/ethnicity, and grade. Results: In 2010, 63.1% of students missed breakfast, 38.2% missed lunch, and 23.3% missed dinner; the prevalence was highest among female and non-Hispanic black students. Being overweight/obese, perceiving oneself to be overweight, and video game/computer use were associated with increased risk of missing meals. Physical activity behaviors were associated with reduced risk of missing meals. Students who missed breakfast were less likely to eat fruits and vegetables and more likely to consume sugar-sweetened beverages and fast food. Conclusion: Breakfast was the most frequently missed meal, and missing breakfast was associated with the greatest number of less healthy dietary practices. Intervention and education efforts might prioritize breakfast consumption.

Purpose. To examine behavioral and environmental factors that may be related to dietary behaviors among U.S. high school students. Design. Data were obtained from the 2010 National Youth Physical Activity and Nutrition Study, a cross-sectional study. Setting. The study was school-based. Subjects. Study subjects were a nationally representative sample of students in grades 9 to 12 (n = 11,458). Measures. Variables of interest included meal practices, in-home snack availability, and intakes of healthful foods/beverages (fruits, vegetables, water, and milk) and less healthful foods/beverages (fried potatoes, pizza, and sugar-sweetened beverages). Analysis. Sex-stratified logistic regression models were used to examine associations of meal practices and snack availability with dietary intake. Odds ratios (ORs) were adjusted for race/ethnicity and grade. Results. Eating breakfast daily, frequent family dinners, and bringing lunch from home were associated with higher odds of consuming at least three healthful foods or beverages. High fast-food intake was associated with lower odds of healthful dietary intake and higher odds of sugar-sweetened beverage intake (female OR = 3.73, male OR = 4.60). Students who mostly/always had fruits and vegetables available at home had increased odds of fruits (female OR = 3.04, male OR = 2.24), vegetables (female OR = 2.12, male OR = 1.65), water (female OR = 1.82, male OR = 1.85), and milk intake (female OR = 1.45, male OR = 1.64). Conclusion. Encouraging daily breakfast consumption, frequent family dinners, and fruit and vegetable availability at home may lead to higher intakes of healthful foods among high school students.
