Second, most studies do not examine heterogeneity in the impact of the lockdown on drinking patterns. Yet, there may be differences between groups of individuals. For instance, the living arrangements in which individuals faced the lockdown -i.e. whether they lived alone or a shared a household with partner and/or family- may be relevant (Corbin et al., 2020, Skrzynski and Creswell, 2020). Accordingly, studies analysing the impact of the lockdown on mental health have shown that the effect was stronger for individuals who lived alone (Ahrens et al., 2021), whereas others have shown that those with children in the household during the lockdown suffered higher stress levels, which may have exposed them to increased alcohol consumption (Villanueva-Blasco et al., 2021).
