Alcohol consumption increases the risk of several cancers, but public awareness of alcohol as a risk factor for cancer is low. Research indicates that public opinion about alcohol related policies can be influenced by mass media campaigns and awareness of alcohol as a carcinogen. The objective of this study was to test whether a mass media campaign intended to raise awareness of the relation between alcohol and cancer is associated with higher public awareness of alcohol as a risk factor for cancer, and higher levels of support for alcohol related policies. Cross-sectional surveys of a nationally representative sample of N = 6000 Danish adults were conducted pre- (n = 3000) and post campaign (n = 3000) in 2017-2018. Awareness of alcohol as a cancer risk factor significantly increased between the pre and post campaign survey (approximately 5 percentage points). The proportion of respondents who supported minimum unit pricing, a ban on alcohol advertising, and mandatory nutrition labelling was significantly higher post campaign than pre campaign, while support for limited number of retail outlets and limited sale hours were unchanged. For males, but not females, higher support for an 18 year age limit for purchasing alcohol, age limits for buying alcohol at secondary education school parties, and increased enforcement of age limits was found after the campaign than prior to it. Conclusively, the results show that a mass media campaign was associated with an increase in awareness of alcohol as a risk factor for cancer as well as alcohol policy support at a population level.
饮酒会增加罹患多种癌症的风险，但公众对酒精致癌风险的认识较低。研究表明，公众对酒精相关政策的看法可能会受到大众媒体宣传和对酒精致癌性认识的影响。本研究的目的是检验旨在提高公众对酒精与癌症之间关系的认识的大众媒体宣传活动是否与公众对酒精作为癌症风险因素的认识的提高以及对酒精相关政策的支持程度的提高有关。在 2017-2018 年，对丹麦全国代表性的 6000 名成年人进行了横断面调查，分别在宣传活动前（n=3000）和宣传活动后（n=3000）进行。在宣传活动前后，公众对酒精致癌风险的认识显著提高（约 5 个百分点）。宣传活动后，支持最低单位定价、禁止酒精广告和强制营养标签的受访者比例明显高于宣传活动前，而对限制零售店数量和销售时间的支持则保持不变。仅在男性中，而不是在女性中，在宣传活动后比宣传活动前发现对购买酒精的年龄限制为 18 岁、在中学派对上购买酒精的年龄限制以及对年龄限制的执法力度增强的支持率更高。总而言之，结果表明，大众媒体宣传活动与公众对酒精作为癌症风险因素的认识的提高以及在人群层面上对酒精政策的支持有关。
