Marketing on television showcases less-healthful options, with emerging research suggesting movies promote similar products. Given the obesity epidemic, understanding advertising to youth should be a public health imperative. The objective of this study was to estimate youth impressions to food and beverages delivered through movies.
Impressions were calculated by dividing US receipts annually into average movie ticket prices, then multiplying this by the number of brand appearances. Examination by ratings, product types and ages were conducted by Spearman rank correlation coefficient tests.
Youth in the USA saw over 3 billion food, beverage or food-retail establishment (FRE) impressions on average, annually from 1996 to 2005. Those aged 12-18 viewed over half of all impressions, with PG-13-rated movies containing 61.5% of impressions. There were no significant trends in brand appearances by food, beverage or FRE impressions over the decade, although there was a decreasing trend in R-rated impressions for both foods (P< 0.01) and beverages (P< 0.01), but not FREs (P= 0.08).
Movies promote billions of food and beverage impressions annually to youth. Given the public health crisis of obesity, future research should further investigate these trends, as well as the potential association of these unhealthy exposures in youth.
电视广告宣传了许多不够健康的选择,新兴研究表明电影也在推销类似的产品。鉴于肥胖症的流行,了解年轻人的广告宣传应该是公共卫生的当务之急。本研究旨在估计电影中所呈现的食品和饮料对年轻人的影响。
通过将美国每年的票房收入除以平均电影票价,然后将其乘以品牌出现的次数,来计算印象数。通过 Spearman 秩相关系数检验,对收视率、产品类型和年龄进行了检验。
1996 年至 2005 年,美国年轻人每年平均观看超过 30 亿次食品、饮料或食品零售企业(FRE)的广告印象。年龄在 12-18 岁之间的年轻人观看了所有印象的一半以上,PG-13 级电影中包含 61.5%的广告印象。在这十年中,食品、饮料或 FRE 印象的品牌出现次数没有明显的趋势,但 R 级电影的食品(P<0.01)和饮料(P<0.01)的印象数量呈下降趋势,而 FRE 则没有(P=0.08)。
电影每年向年轻人宣传数十亿次的食品和饮料广告。鉴于肥胖症这一公共卫生危机,未来的研究应该进一步调查这些趋势,以及年轻人接触这些不健康广告的潜在关联。
