Abstract：
To evaluate the effectiveness of a French mass-media campaign in raising knowledge of both long-term alcohol-related harms (LTH) and low-risk drinking guidelines (LRDG), as well as in lowering alcohol consumption.
An 8-month longitudinal survey from February to October 2019, with three waves of on-line data collection (T0 before the campaign, T1 just after it ended and T2 6 months after it ended).
France.
A total of 2538 adult drinkers (aged 18-75 years).
The main outcomes\' variables were LTH knowledge (cancer, hypertension, brain haemorrhage), LRDG knowledge (two guidelines: \'maximum of two drinks a day\' and \'minimum of 2 days without alcohol per week\'), intention to reduce alcohol consumption and self-declared consumption with respect to the French LRDG. At T1, exposure to the campaign was measured using self-reported campaign recall.
In T1, we observed significant positive interactions between exposure group based on campaign recall and survey waves on knowledge of (i) the \'maximum two drinks a day\' guideline [adjusted odds ratio (aOR) = 1.32, 95% confidence interval (CI) = 1.08-1.62, P = 0.008], (ii) brain haemorrhage (aOR = 1.80, 95% CI = 1.44-2.25, P < 0.001) and (iii) hypertension (aOR = 1.41, 95% CI = 1.09-1.81, P = 0.008) risks. Campaign exposure was also associated with a significant decrease in at-risk drinking in women (aOR = 0.67, 95% CI = 0.50-0.88, P = 0.004). No significant interaction was observed at T1 for the knowledge of the \'minimum of 2 days without alcohol a week\' guideline, or of cancer risk. At T2, no significant interaction was observed for the main outcomes\' variables.
There appears to be an association between exposure to a 2019 French mass-media campaign to raise knowledge of long-term alcohol-related harms and low-risk drinking guidelines and reduce alcohol consumption and (i) improved knowledge of the \'maximum two drinks per day guideline\', (ii) knowledge of the risks of hypertension and brain haemorrhage and (iii) a reduction in the proportion of people exceeding low-risk drinking guidelines (in the general population only). These associations were only observed over the short term and, in some cases, only for certain segments of the population.

摘要：
目的：评估法国大众媒体宣传活动在提高对长期酒精相关危害（LTH）和低风险饮酒指南（LRDG）的认识方面的有效性，以及减少酒精消费。
方法：从2019年2月至10月进行了为期8个月的纵向调查，进行了三波在线数据收集（活动前T0，T1刚结束，和T26个月后结束)。
方法：法国参与者：2,538名成人饮酒者（18-75岁）测量：主要结果变量是LTH知识（癌症，高血压,脑出血)，LRDG知识（两个准则：\“每天最多喝2杯”和\“每周最少不喝酒2天”），减少饮酒的意图，以及关于法国LRDG的自我申报消费。在T1时，使用自我报告的活动召回来测量活动的暴露。
结果：在T1中，我们根据活动回忆和关于i的知识的调查波观察到暴露组之间的显着正相互作用）\“每天最多2杯”指南（调整后的优势比[aOR]1.32[95％置信区间1.08-1.62]，p=0.008),ii）脑出血（aOR=1.80[1.44-2.25]，p<0.001)，和iii)高血压(aOR=1.41[1.09-1.81]，p=0.008）风险。运动暴露也与女性饮酒风险显着下降有关（aOR=0.67[0.50-0.88]，p=0.004)。对于“每周至少2天不饮酒”指南的知识，在T1时未观察到明显的相互作用，或癌症风险。在T2时，没有观察到主要结果变量的显著交互作用。
结论：接触2019年法国大众媒体宣传活动以提高对长期酒精相关危害的认识，与低风险饮酒指南（LRDG）和减少饮酒和i）提高对“每天最多喝2杯”的认识之间似乎存在关联。ii）了解高血压和脑出血的风险，和iii）减少超过LRDG的人口比例（仅在普通人群中）。这些关联仅在短期内观察到，在某些情况下,仅适用于某些人群。
