Introduction: The COVID-19 outbreak and the related lockdown measures have raised concerns regarding mental health, including alcohol misuse. Preliminary studies investigated alcohol consumption at the early stages of lockdown, but no longitudinal data regarding its evolution during and after the first lockdown are currently available. Methods: We investigated changes in alcohol consumption among a convenience sample of 1,693 French-speaking Belgian adults using a 3-stage longitudinal online survey. All participants reported their consumption at different stages of lockdown: before lockdown onset (retrospectively, T0), at 2 different times during lockdown (T1 and T2), and after lockdown offset (T3). We also measured socio-demographic variables and the harmfulness of drinking patterns before lockdown. Results: A mixed model with negative binomial distribution indicated that participants decreased their alcohol consumption after lockdown onset and returned to their initial alcohol consumption after lockdown offset. Younger individuals (18–30 years old) were more likely to decrease their consumption during the lockdown period (T1 and T2) than the periods preceding or following lockdown (T0 and T3), especially if they presented hazardous or problematic drinking patterns before lockdown. We only observed a rebound effect after lockdown offset among young moderate drinkers. All participants kept stable their alcohol consumption during lockdown (T1 and T2). Conclusions: Lockdown onset and offset constitute key periods for alcohol consumption changes during the COVID-19 crisis, particularly in youth and in individuals with hazardous or problematic drinking patterns.

在第一次 COVID-19 封锁期间对酒精消费的纵向评估：年龄和大流行前饮酒模式的贡献

简介： COVID-19 爆发和相关的封锁措施引起了人们对心理健康的担忧，包括酗酒。初步研究调查了锁定早期阶段的饮酒量，但目前尚无有关其在第一次锁定期间和之后的演变的纵向数据。方法：我们使用 3 阶段纵向在线调查调查了 1,693 名讲法语的比利时成年人的便利样本中酒精消费的变化。所有参与者都报告了他们在锁定的不同阶段的消费情况：锁定开始之前（追溯 T0）、锁定期间的 2 个不同时间（T1 和 T2）以及锁定偏移之后（T3）。我们还在封锁前测量了社会人口变量和饮酒方式的危害。结果：具有负二项分布的混合模型表明，参与者在锁定开始后减少了饮酒量，并在锁定抵消后恢复了初始饮酒量。与锁定之前或之后的时期（T0 和 T3）相比，年轻人（18-30 岁）更有可能在锁定期间（T1 和 T2）减少他们的消费，特别是如果他们在锁定之前呈现出危险或有问题的饮酒模式。我们只观察到年轻适度饮酒者在锁定抵消后的反弹效应。所有参与者在锁定期间（T1 和 T2）保持稳定的饮酒量。结论：在 COVID-19 危机期间，特别是在年轻人和有危险或有问题的饮酒模式的个人中，封锁开始和取消构成了酒精消费变化的关键时期。
