A health warning label (HWL) cautioning about the link between alcohol and cancer may be able to communicate alcohol risks to consumers and potentially counter health-oriented nutrition advertising on ready-to-drink alcoholic beverages. This study aimed to examine the independent and combined effects of nutrient content claims (e.g. 0 g sugar) and a HWL on perceived product characteristics and intentions to consume, and whether these effects differed by gender and age.
A between-subjects randomized experiment. Participants were randomized to view one of six experimental label conditions: nutrient content claims plus nutrition declaration (NCC + ND), ND only, NCC + ND + HWL, ND + HWL, HWL only and no NCC, ND or HWL, all on a ready-to-drink (RTD) vodka-based soda container.
Alcohol consumers (n = 5063; 52% women) in Canada aged 18-64 recruited through a national online panel.
Participants completed ratings of perceived product characteristics, perceived product health risks, and intentions to try, buy, binge and drink the product.
Compared with the reference condition NCC + ND (current policy scenario in Canada), the other five experimental label conditions were associated with lower ratings for perceiving the product as healthy. All experimental conditions with a HWL were associated with lower product appeal, higher risk perceptions and reduced intentions to try, buy and binge. The experimental condition with a HWL only was associated with intentions to consume fewer cans in the next 7 days (β = -0.72, 95% confidence interval [CI] = -1.37,-0.08) versus the reference. Few interactions were observed, suggesting that label effects on outcomes were similar by gender and age.
Health warning labels on alcohol packaging appear to be associated with lower product appeal, higher perceived health risks and reduced consumption intentions, even in the presence of nutrient content claims.
一个健康警示标签（HWL）警告酒精和癌症之间的联系，可能能够向消费者传达酒精风险，并可能对抗即饮酒精饮料的以健康为导向的营养广告。本研究旨在检验营养素含量声明（例如 0 克糖）和 HWL 对感知产品特征和消费意愿的独立和综合影响，以及这些影响是否因性别和年龄而异。
一项基于受试者的随机实验。参与者被随机分配到六个实验标签条件之一：营养素含量声明加营养声明（NCC + ND）、仅 ND、NCC + ND + HWL、ND + HWL、HWL 仅和没有 NCC、ND 或 HWL，全部在一种即饮（RTD）伏特加苏打水容器上。
在加拿大通过全国在线小组招募的 18-64 岁的酒精消费者（n = 5063；52%为女性）。
参与者完成了对感知产品特征、感知产品健康风险和尝试、购买、狂饮和饮用产品的意愿的评分。
与参考条件 NCC + ND（加拿大当前政策情景）相比，其他五个实验标签条件与对产品健康的感知较低相关。所有带有 HWL 的实验条件均与产品吸引力降低、风险感知增加以及尝试、购买和狂饮的意愿降低相关。仅带有 HWL 的实验条件与在接下来的 7 天内消费更少罐的意图相关（β = -0.72，95%置信区间 [CI] = -1.37，-0.08）与参考相比。观察到很少的交互作用，这表明标签对结果的影响在性别和年龄上相似。
即使存在营养素含量声明，酒精包装上的健康警示标签似乎也与产品吸引力降低、感知健康风险增加和消费意愿降低有关。
