Junk Food Consumption and Screen Time: Association With Childhood Adiposity

Abstract

Objectives: To determine the joint association of junk food consumption (JFC) and screen time (ST) with adiposity in children. Methods: Two hundred fourteen (121 girls, 93 boys) third-to-fifth-grade students (54% Hispanic, 35% African American, 8% white) completed a lifestyle behavior survey, which included self-reported JFC and ST, as part of a school-based lifestyle intervention program. Results: Neither JFC nor ST, independently or jointly, was associated with adiposity measures. JFC and ST were significantly correlated (r = .375). Conclusions: The low achievement of physical activity and screen time recommendations and high prevalence of overweight/obesity in this mostly minority, low socioeconomic status population indicates a potential focus for intervention.
