To investigate whether alcoholic beverages popular among underage youths are more likely than those less popular among these youths to be advertised in magazines with high underage youth readerships.
We compared the alcohol advertisement placement in 118 magazines during the period 2002 to 2006 for alcoholic beverages popular among youths to that of alcoholic beverages less likely to be consumed by youths. Using a random effects probit model, we examined the relationship between a magazine's youth (ages 12-20) readership and the probability of youth or nonyouth alcoholic beverage types being advertised in a magazine, controlling for young adult (ages 21-34) readership, cost of advertising, and other factors.
Youth alcoholic beverage types were significantly more likely to be advertised in magazines with higher youth readership. Holding all other variables constant, the ratio of the probability of a youth alcoholic beverage type being advertised to that of a nonyouth alcoholic beverage type being advertised in a given magazine increased from 1.5 to 4.6 as youth readership increased from 0% to 40%. In magazines with the highest levels of youth readership, youth alcoholic beverage types were more than four times more likely to be advertised than nonyouth alcoholic beverage types.

调查在青少年中流行的酒精饮料是否比那些在青少年中不太受欢迎的酒精饮料更有可能在青少年阅读率较高的杂志上做广告。
我们比较了 2002 年至 2006 年间 118 种杂志中青少年(12-20 岁)和非青少年(21-34 岁)读者的酒精饮料广告投放情况。采用随机效应概率模型,控制年轻成人(21-34 岁)读者、广告成本和其他因素,检验杂志的青年读者与杂志刊登青年或非青年酒精饮料类型广告的概率之间的关系。
青年酒精饮料类型在青年读者比例较高的杂志上做广告的可能性显著更高。在其他所有变量保持不变的情况下,给定杂志中青年酒精饮料类型的广告概率与非青年酒精饮料类型的广告概率之比从 1.5 增加到 4.6,当青年读者比例从 0%增加到 40%。在青年读者比例最高的杂志中,青年酒精饮料类型的广告刊登率是非青年酒精饮料类型的四倍多。
在青少年阅读率较高的杂志上,在青少年中流行的酒精饮料比那些在青少年中不太受欢迎的酒精饮料更有可能做广告。
