This study investigated variables that may mediate the relationship between advertising susceptibility and adolescent preference for and consumption of sugar-sweetened beverages (SSBs), with the goal of informing inoculation-based mitigation approaches grounded in media literacy and messaging resistance.
The study utilized data from a nationally representative sample of US adolescents (ages 12-17 years, n = 1,657) from the National Cancer Institute's Family Life, Activity, Sun, Health, and Eating survey.
Variables of interest were SSB preference and consumption, advertising susceptibility, perceived self-efficacy to make good nutritional choices, perceived SSB consumption by peers, and attitude toward SSBs. Exposure to obesogenic environments was examined as a moderator.
Direct and mediated associations between advertising susceptibility and SSB preference were estimated through a series of regression and mediation analyses.
Advertising susceptibility was a strong predictor of SSB preference (unstandardized B = .29, SE = .026, P < .001), which, in turn, was a strong predictor of consumption (unstandardized B = .10, SE = .01, P < .001), controlling for potential mediators. The only statistically significant mediator of this association was perceived peer consumption (unstandardized B = .38, SE = .08, P < .001), which was stronger for adolescents with higher exposure to obesogenic environments.
This study offers developers of inoculation-based strategies additional insight into levers that could be targeted for building adolescent resistance to advertising effects.
本研究调查了可能介导广告易感性与青少年对含糖饮料（SSB）的偏好及消费之间关系的变量，旨在为基于媒介素养和信息抵制的预防接种式缓解方法提供依据。
该研究使用了美国国立癌症研究所“家庭生活、活动、阳光、健康和饮食”调查中具有全国代表性的美国青少年样本（12 - 17岁，n = 1657）的数据。
感兴趣的变量包括对SSB的偏好和消费、广告易感性、做出良好营养选择的自我效能感、对同龄人SSB消费的认知以及对SSB的态度。将暴露于致胖环境作为一个调节因素进行了考察。
通过一系列回归和中介分析估计了广告易感性与SSB偏好之间的直接和中介关联。
在控制潜在中介因素后，广告易感性是SSB偏好的有力预测因素（非标准化B = 0.29，标准误 = 0.026，P < 0.001），而SSB偏好又是消费的有力预测因素（非标准化B = 0.10，标准误 = 0.01，P < 0.001）。该关联中唯一具有统计学意义的中介因素是对同龄人消费的认知（非标准化B = 0.38，标准误 = 0.08，P < 0.001），对于暴露于致胖环境程度较高的青少年，这种中介作用更强。
本研究为基于预防接种策略的开发者提供了更多见解，有助于确定可针对增强青少年对广告影响的抵抗力的关键因素。
