The question of whether underage youth are disproportionately exposed to alcohol advertising lies at the heart of the public health debate about whether restrictions on alcohol advertising are warranted. The aim of this study was to determine whether alcohol brands popular among underage (ages 12 to 20 years) drinkers ("underage brands") are more likely than others ("other brands") to advertise in magazines with high underage readerships.
We analyze the advertising of 680 alcohol brands in 49 magazines between 2006 and 2011. Using a random effects probit model, we examine the relationship between a magazine's underage readership and the probability of an underage or other brand advertising in a magazine, controlling for young adult (ages 21 to 29 years) and total readerships, advertising costs and expenditures, and readership demographics.
We find that underage brands are more likely than other brands to advertise in magazines with a higher percentage of underage readers. Holding all other variables constant at their sample means, the probability of an "other" brand advertising in a magazine remains essentially constant over the range of underage readership from 0.010 (95% confidence interval [CI], 0.007 to 0.013) at 5% to 0.012 (95% CI, 0.008 to 0.016) at 35%. In contrast, the probability of an underage brand advertising nearly quadruples, ranging from 0.025 (95% CI, 0.015 to 0.035) to 0.096 (95% CI, 0.057 to 0.135), where underage brands are 7.90 (95% CI, 3.89 to 11.90) times more likely than other brands to advertise.
Alcohol brands popular among underage drinkers are more likely than other brands to advertise in magazines with high underage readerships, resulting in the disproportionate exposure of underage youth. Current voluntary advertising industry guidelines are not adequate to protect underage youth from high and disproportionate exposure to alcohol advertising in magazines. To limit advertising exposure among underage youth, policy makers may want to consider regulation of alcohol advertising in magazines.
未成年人是否不成比例地接触到酒精广告,这是关于是否有理由限制酒精广告的公共卫生辩论的核心问题。本研究的目的是确定在杂志上,未成年(12 至 20 岁)饮酒者中受欢迎的酒精品牌(“未成年品牌”)是否比其他品牌(“其他品牌”)更有可能在未成年读者比例较高的杂志上做广告。
我们分析了 2006 年至 2011 年间 49 本杂志上的 680 个酒精品牌的广告。使用随机效应概率模型,我们考察了杂志的未成年读者比例与未成年或其他品牌在杂志上做广告的概率之间的关系,同时控制了年轻成年人(21 至 29 岁)和总读者、广告成本和支出以及读者人口统计数据。
我们发现,未成年品牌比其他品牌更有可能在未成年读者比例较高的杂志上做广告。在其他所有变量保持在样本均值的情况下,“其他”品牌在杂志上做广告的概率在未成年读者比例从 5%的 0.010(95%置信区间[CI],0.007 至 0.013)到 35%的 0.012(95% CI,0.008 至 0.016)的范围内基本保持不变。相比之下,未成年品牌做广告的概率几乎增加了四倍,从 5%的 0.025(95% CI,0.015 至 0.035)到 35%的 0.096(95% CI,0.057 至 0.135),未成年品牌做广告的可能性是其他品牌的 7.90 倍(95% CI,3.89 至 11.90)。
在未成年饮酒者中受欢迎的酒精品牌比其他品牌更有可能在未成年读者比例较高的杂志上做广告,从而导致未成年青少年不成比例地接触到酒精广告。目前,自愿性广告行业准则不足以保护未成年青少年免受杂志上酒精广告的高比例和不成比例的影响。为了限制未成年青少年的广告接触,政策制定者可能希望考虑对杂志上的酒精广告进行监管。
