India, being the third worst affected country from COVID-19 pandemic at the time of study, faced complete lockdown to minimize community transmission that confined people to social isolation for extended durations. Therefore, we conducted an online questionnaire-based survey for the Indian population after 37 days of complete lockdown to assess the integrative effects of such home restriction and social isolation on mid-sleep time, social jetlag, and their associated psychosocial behavior. From the reports of sleep onset and waking-up times before and during lockdown as obtained from a total of 1511 respondents of ≥18 years, midsleep time (MST) and social jetlag (SJL) were calculated. Participants also rated their psychosocial behavior related variables on a Likert scale. Significantly delayed MST was noted during the lockdown. The majority showed reduced social jetlag; however, younger people and female subjects exhibited more SJL with delay in MST. Also, delayed MST and elevated SJL problems were more clearly demonstrated in people exhibiting more disturbances in sleep quality and daily routine, lower general mood status, irregular feeding habits (snacking frequency), worsened personal relationship, quality of life, and increased daydreaming events. The study emphasizes the importance of maintaining a regular daily routine with respect to sleep-wake patterns and eating habits to minimize the impact of such a crisis situation on sleep behavior, social jetlag, and associated psychosocial wellbeing.
在本研究开展时，印度是受新冠疫情影响第三严重的国家，为尽量减少社区传播，印度实施了全面封锁，导致人们长期处于社会隔离状态。因此，在全面封锁37天后，我们针对印度人群开展了一项基于在线问卷的调查，以评估这种居家限制和社会隔离对睡眠时间中点、社会时差及其相关心理社会行为的综合影响。根据1511名18岁及以上受访者提供的封锁前和封锁期间入睡时间和起床时间报告，计算出睡眠时间中点（MST）和社会时差（SJL）。参与者还根据李克特量表对其心理社会行为相关变量进行评分。研究发现，封锁期间睡眠时间中点显著延迟。大多数人社会时差减小；然而，年轻人和女性的社会时差更大，且睡眠时间中点延迟。此外，睡眠质量和日常生活受到更多干扰、总体情绪状态较低、饮食习惯不规律（零食频率）、人际关系恶化、生活质量下降以及白日梦事件增多的人群，睡眠时间中点延迟和社会时差问题加剧的情况更为明显。该研究强调了在睡眠-清醒模式和饮食习惯方面保持规律日常作息的重要性，以尽量减少此类危机情况对睡眠行为、社会时差及相关心理社会健康的影响。
