The prevalence of childhood obesity has increased worldwide and various environmental factors have accelerated this trend. Several reports have suggested that food advertising causes childhood obesity. We proposed a review study to evaluate the relationship between TV food advertisements and obesity in children. By searching over electronic databases (including PubMed, Web of Science, Scopus, and Google Scholar), the reference lists of original studies, and reviews using key search terms, 1181 articles were identified. Out of these, only 9 articles met the inclusion and quality criteria. Most of the longitudinal study carried out at the national level have reported a significant association between commercial viewing and BMI in children. The duration of these studies varied between 7 months and 5 years. The children's TV viewing time was between 1.5 and 3.5 hours per day. Results of the reviewed studies have revealed a controversial attitude about the influence of TV food advertisements on obesity. However, three of four modeling studies indicated an increment in the prevalence of overweight and obesity following exposure to food advertisements. Further interventional and longitude studies are needed to achieve more precise results.
儿童肥胖症的患病率在全球范围内不断上升，各种环境因素加速了这一趋势。有几项报告表明，食品广告会导致儿童肥胖。我们提出了一项综述研究，以评估电视食品广告与儿童肥胖之间的关系。通过在电子数据库（包括 PubMed、Web of Science、Scopus 和 Google Scholar）、原始研究的参考文献列表以及使用关键搜索词进行的综述中进行搜索，共确定了 1181 篇文章。其中，只有 9 篇文章符合纳入和质量标准。在国家层面进行的大多数纵向研究报告称，商业广告观看与儿童 BMI 之间存在显著关联。这些研究的持续时间在 7 个月至 5 年之间不等。儿童每天看电视的时间在 1.5 到 3.5 小时之间。已审查研究的结果表明，对于电视食品广告对肥胖的影响存在争议态度。然而，四项建模研究中有三项表明，接触食品广告后，超重和肥胖的患病率会增加。需要进一步的干预和纵向研究来得出更精确的结果。
