背景和目的：不健康的饮食行为随着年龄的增长而增加，并与成年后的不良健康后果有关。我们在近6万名有代表性的青少年样本中研究了屏幕久坐行为(SBS)对不健康食物消费的影响，如高能量食物和含糖饮料，并评估了可能的调节剂的作用。方法：数据来自意大利2009-10年学龄儿童健康行为调查(HBSC)。根据HBSC研究方案收集关于饮食模式、SBS、体力活动、同伴网络、BMI和社会经济状况(SES)的数据。采用分层Logistic回归模型。结果：不健康食物摄入与水果和蔬菜摄入量减少以及SBS增加有关，无论男女和各年龄段。有趣的是，在正常体重的青少年、那些与同龄人有更广泛关系的人和低SES儿童中，风险更高。结论：这项研究增加了证据，支持在教育举措上投入更多资源的重要性，这些举措包括提高父母的意识，支持青少年的饮食选择和花在屏幕上的行为上的时间，而不考虑他们的肥胖状况；以及发展年轻人获得和适当使用媒体和技术的能力。政策制定者还应更多地关注对年轻人接触的电视食品广告实行监管政策。
Backgrounds and aim: Unhealthy eating behaviours increase with age and have been associated with adverse health consequences in adulthood. We examined the influence of screen-based sedentary behaviours (SBs) on unhealthy food consumption, such as energy-dense foods and sweetened drinks, among a representative sample of nearly 60 000 adolescents and assessed the role of possible modifiers. Methods: Data come from the Italian 2009-10 Health Behaviour in School-aged Children (HBSC) survey. Data on Eating patterns, SBs, physical activity, peers network, BMI and socio-economic status (SES) were collected following the HBSC study protocol. Hierarchical logistic regression models were used. Results: Unhealthy food consumption was significantly associated with a lower intake of fruit and vegetables and with the increase of SBs in both sexes and in all ages. The risk was interestingly higher in normal weight adolescents, in those with wider relationships with peers and in low SES children. Conclusions: This study adds evidence to support the importance of investing more resources in educational initiatives both to increase parents' awareness to support adolescents on dietary choices and on time spent in screen-based behaviours, independently of their adiposity status; and to develop youth's ability to access and appropriately use media and technologies. Policy makers should also increase their attention on introducing regulatory policies on television food advertising to which youth are exposed.
