(1) Background: The lockdown, imposed to limit the pandemic evolution, impacted the social habits and lifestyle of inhabitants also from many countries other than Italy. Caffeine consumption could be a useful option to improve mood, as the lockdown strongly affected mental health, particularly increasing anxiety and sleep disorders. (2) Methods: It was a cross-sectional study aimed to evaluate the change in caffeine consumption after the pandemic period in a sample of Italian University students. It investigated coffee and products containing caffeine consumption, the anxiety level by State Trait Anxiety Inventory (STAI) and sleep quality with the Insomnia Severity Index (ISS). (3) Results: A total of 404 participants were enrolled in the study. During the lockdown period, 23% of subjects consumed more coffee compared to the pre-pandemic period. Daily coffee consumption also changed after the lockdown period compared to the pre-pandemic period, with 36.1% of subjects that increased their consumption. Comparing other caffeine-based products, energizing supplement consumption showed a greater increase after the lockdown period than energy drinks. Regarding anxiety, subjects who reported increased coffee consumption reported higher STAI scores and ISS. (4) Conclusions: About a quarter of university students increased their consumption of caffeine-based products after the pandemic, reporting higher levels of anxiety and poor sleep quality.
(1) 背景：为限制疫情发展而实施的封锁措施，也对意大利以外许多国家居民的社会习惯和生活方式产生了影响。由于封锁对心理健康产生了强烈影响，尤其是增加了焦虑和睡眠障碍，咖啡因摄入可能是改善情绪的一个有效选择。(2) 方法：这是一项横断面研究，旨在评估疫情期间后意大利大学生样本中咖啡因摄入量的变化。该研究调查了咖啡及含咖啡因产品的摄入量、通过状态特质焦虑量表（STAI）评估的焦虑水平以及通过失眠严重程度指数（ISS）评估的睡眠质量。(3) 结果：共有404名参与者纳入该研究。在封锁期间，23%的受试者比疫情前饮用了更多咖啡。与疫情前相比，封锁期过后每日咖啡摄入量也发生了变化，36.1%的受试者增加了咖啡摄入量。比较其他含咖啡因产品，与能量饮料相比，封锁期过后提神补充剂的消费量增长幅度更大。关于焦虑，报告咖啡摄入量增加的受试者STAI得分和ISS更高。(4) 结论：疫情过后，约四分之一的大学生增加了含咖啡因产品的摄入量，报告显示他们的焦虑水平更高且睡眠质量较差。
