Abstract

The present study examines the energy intake resulting from eating snacks and drinking energy containing drinks while watching television. 2546 first and fourth year students in a random sample of 15 secondary schools in Flanders, Belgium received quantifiable, closed survey questions about average weekly TV viewing volume and about eating five types of snacks and drinking two types of soft drinks. On an average, the respondents watched 22:27 h of television per week (SD = 11:53). Only 3.5% of the adolescents never eat snacks or drink soft drinks while they watch TV. Estimated daily energy intake accompanying TV viewing amounts to 19% of the Belgian average energy allowance (AEA) in boys and between 12 and 14% of AEA in girls. On an average 1 h of watching television equals the consumption of 653 kJ.

摘要

本研究调查了边看电视边吃零食和喝含能量饮料所导致的能量摄入情况。比利时弗拉芒地区15所中学的2546名一年级和四年级学生，收到了关于平均每周看电视时长以及食用五种零食和饮用两种软饮料情况的可量化封闭式调查问卷。受访者平均每周看电视22小时27分钟（标准差=11小时53分钟）。只有3.5%的青少年在看电视时从不吃零食或喝软饮料。看电视时估计的每日能量摄入量，在男孩中占比利时平均能量摄入量（AEA）的19%，在女孩中占AEA的12%至14%。平均来看，观看1小时电视相当于消耗653千焦能量。
