Objective: To examine the cross-sectional and longitudinal relationships between television viewing and preferred food choices in a sample of ethnic minority, low income adolescents. Methods: A sample of predominantly minority students (n=133) completed surveys at two time points, six months apart. Linear regression models examined television viewing and eating associations. Results: Participants watched >3.5 hours/day of television, which is similar to the national average. Positive cross-sectional relationships existed between television viewing with fast food and sweetened beverage intakes at Time 1 and with snack food intake at both time points (p<0.01). The longitudinal association between change in snack food intake and change in average television hours/day approached significance after adjusting for baseline measure (β=0.305, p=0.017), as did the relationship with family meals (β=-0.20, p=0.02). No other longitudinal relationships were significant. Conclusions and implications: If interventions reduced adolescents television viewing time, such interventions could positively impact eating habits and thereby reduce adolescents risk for obesity.
