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.
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.
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.
TV viewing time might be a focal point for prevention of both eating disorders and obesity in adolescence.
针对青少年饮食失调和肥胖的有效预防干预措施应聚焦于共同的风险因素。我们分析了看电视时间与饮食失调风险之间的关联，以及肥胖在这种关联中的潜在作用。
样本包括来自青少年营养状况评估（AVENA）和青少年超重、肥胖、过敏、感染及心血管危险因素发展的体育活动预防措施（AFINOS）研究的3458名13至18.5岁的西班牙青少年。青少年的看电视时间通过自我报告进行评估。计算体重指数，并将青少年分为非超重和超重肥胖组。使用SCOFF问卷评估饮食失调风险。
与每天看电视时间少于1小时的青少年相比，每天看电视超过1小时的青少年患饮食失调的风险更高。此外，超重肥胖的青少年患饮食失调的风险高于非超重青少年。对看电视时间和体重状况组的分析显示出类似趋势，即无论体重状况如何，看电视时间越长，患饮食失调的风险越高。
看电视时间可能是预防青少年饮食失调和肥胖的一个重点。
