Adverse alcohol consumption is a major public health concern, which might have been further increased by the COVID-19 pandemic. In this study we investigated the impact of a lockdown stage on the association between alcohol consumption, loneliness, and COVID-19-related worries. We used smartphone-based Ecological Momentary Assessment (EMA) conducted during the COVID-19 pandemic in Germany. We recruited 280 participants from the general population, who experienced at least mild loneliness and distress due to the COVID-19 pandemic. We assessed daily alcohol intake, loneliness, and COVID-19-related worries every evening for 7 consecutive days across a no-lockdown [8th August 2020-1st November 2020] and lockdown stage [2nd November 2020-11th March 2021]. We did not find that a lockdown stage, compared to a no-lockdown stage, is associated with increased alcohol consumption. We found that loneliness, previous day drinking, and COVID-19-related worries were not associated with increased, but with decreased alcohol consumption. Moreover, COVID-19-related worries were more negatively associated with alcohol consumption during a no-lockdown stage compared to a lockdown stage. We found that the effect of COVID-19 related worries on alcohol consumption is mediated by loneliness. Our study suggests that heightened levels of worry can decrease alcohol intake. This association can be explained by loneliness: individuals who worry more are lonelier and thus less likely to engage in social drinking. However, during a lockdown stage, the negative association between worrying and drinking diminishes.
有害饮酒是一个重大的公共卫生问题，在新冠疫情期间这一问题可能进一步加剧。在本研究中，我们调查了封锁阶段对饮酒、孤独感和新冠相关担忧之间关联的影响。我们使用了在德国新冠疫情期间基于智能手机的生态瞬时评估（EMA）。我们从普通人群中招募了280名参与者，他们因新冠疫情至少经历了轻度的孤独感和痛苦。我们在一个非封锁阶段[2020年8月8日至2020年11月1日]和封锁阶段[2020年11月2日至2021年3月11日]连续7天每天晚上评估每日酒精摄入量、孤独感和新冠相关担忧。我们没有发现与非封锁阶段相比，封锁阶段与酒精消费增加有关。我们发现孤独感、前一天饮酒以及新冠相关担忧与酒精消费增加无关，而是与减少有关。此外，与封锁阶段相比，在非封锁阶段新冠相关担忧与酒精消费的负相关性更强。我们发现新冠相关担忧对酒精消费的影响是由孤独感介导的。我们的研究表明，担忧程度的增加会减少酒精摄入量。这种关联可以用孤独感来解释：担忧更多的人更孤独，因此参与社交饮酒的可能性更小。然而，在封锁阶段，担忧和饮酒之间的负相关减弱。
