最近的一篇文献综述得出的结论是，电视上的食品广告可能会影响儿童的食物选择并鼓励不健康的饮食，但该综述承认有大量明确的证据可以得出这一结论。本文利用儿童电视广告调查数据以及对美国、澳大利亚和八个欧洲国家儿童超重流行率的估计，研究了儿童广告与超重风险之间联系的生态证据。研究发现，超重儿童的比例与儿童电视上每小时的广告数量之间存在显着关联，尤其是那些鼓励食用高能量、微量营养素匮乏食品的广告（r = 0.81，P < 0.005）。研究发现，超重儿童的比例与鼓励健康饮食的广告数量之间存在较弱的负相关关系（r = -0.56，P < 0.10）。儿童电视上的广告数量似乎与儿童体重超标的普遍程度有关。此外，广告的内容似乎具有特定的效果。研究结果证明有必要采取预防措施来减少儿童接触致肥胖的营销行为。
A recent review of the literature concluded that advertising of foods on television may influence children's food choices and encourage unhealthy diets, but the review acknowledged there was a tack of clear evidence in coming to this conclusion. The present paper examines ecological evidence for a link between advertising to children and the risk of overweight using data from surveys of advertising on children's television and estimates of the prevalence of overweight among children, in the USA, Australia and eight European countries. A significant association was found between the proportion of children overweight and the numbers of advertisements per hour on children's television, especially those advertisements that encourage the consumption of energy-dense, micronutrient-poor foods (r = 0.81, P < 0.005). A weaker, negative association was found between the proportion of children overweight and the number of advertisements encouraging healthier diets (r = -0.56, P < 0.10). The quantity of advertising on children's television appears to be related to the prevalence of excess body weight among children. Furthermore, the content of the advertising appears to have a specific effect. The findings justify the need for taking precautionary measures to reduce children's exposure to obesogenic marketing practices.
