School Lunch Source and Adolescent Dietary Behavior (Preventing Chronic Disease)

Using data from the 2005 California Health Interview Survey, the authors examine the association between dietary behaviors and the number of days that adolescents bring lunch to school. In bivariate analyses, adolescents who typically brought their lunch from home five days per week ate fast food on fewer occasions; consumed fewer servings of soda, fried potatoes and high-sugar foods; and ate more fruit and vegetables compared with adolescents who never brought their lunch to school. In linear regressions controlling for demographics, body mass index, desire to change weight, parent education and adult presence after school, students who typically brought their lunch to school five days per week ate fast food 0.35 fewer times and consumed 0.35 fewer servings of soda, 0.10 fewer servings of fried potatoes, 0.25 fewer servings of high-sugar foods and 0.95 more servings of fruit and vegetables per day compared with students who never brought their lunch to school.

Findings suggest that adolescents who bring lunch to school from home have more positive dietary behaviors than do adolescents who get their lunches from other sources. Improving the nutritional quality of foods offered from other sources, such as the National School Lunch Program and competitive foods, could help improve adolescent dietary behaviors.
