Abstract

Background

Effective preventive interventions for both eating disorders and obesity in adolescence should be focused on shared risk factors. We analyzed the association between television (TV) viewing time and the risk of eating disorders, as well as the potential role of obesity in this association.

Methods

The sample consisted of a total of 3458 Spanish adolescents, aged 13–18.5 years, from the Food and Assessment of the Nutritional Status of Adolescents (AVENA) and Physical Activity as a Preventive Measure of the Development of Overweight, Obesity, Allergies, Infections, and Cardiovascular Risk Factors in Adolescents (AFINOS) studies. Adolescents’ TV time was assessed by self-report. Body mass index was calculated and the adolescents were classified into non-overweight and overweight–obesity. The risk of eating disorders was evaluated using the SCOFF questionnaire.

Results

Adolescents who watched TV >1 h/day had a higher risk for eating disorders, compared with those adolescents who watch TV <1 h/day. Also, overweight–obese adolescents had a higher risk for eating disorders than those who were non-overweight. Analyses across groups of TV viewing time and weight status showed similar trends, so that the higher the time spent in TV viewing, the higher the risk of eating disorders, regardless of weight status.

Conclusions

TV viewing time might be a focal point for prevention of both eating disorders and obesity in adolescence.
