COVID-19 emerged as a serious pandemic in 2019 and billions of people were infected. Various precautionary methods were taken to contain the spread of virus such as social distancing, public lockdown, sanitation, and closure of schools and colleges. Many colleges started online classes to resume their syllabus and to complete the course curriculum. These evening online sessions resulted in late night sleep, long term mobile/computer exposure, and disturbed sleep pattern.
The present study aimed to determine the impact of COVID-19 online classes on morningness- eveningness personality and to compare it with different age groups, gender, and body mass index.
The cluster sampling method was used to collect the subjects from the total of 1153 adult college students, 897 subjects were selected based on the selection criteria and instructed to submit an online survey consists of the Morningness-eveningness Questionnaire and demographic and anthropometric data through mail, social media, or through a researcher by direct interview.
The mean score for the 897 participants is 56.7, indicating intermediate morningness-eveningness personality type. On comparing the different groups, the youngest group (18-20 years) scored 4.23%(mean = 46.7), female subjects scored 6.13%(mean = 58.1), the underweight 2.67%(mean = 59.2) and overweight groups scored 2.89%(mean = 59.7) indicating definite eveningness. Among the 897 collected samples of the population 8.13%of the subjects experienced definite eveningness, 14.93%has moderate eveningness, 17.38%are under intermediate category, 22.4%have moderate morningness, and 37.11%have definite morningness.
Subjects with eveningness personality have high risk of developing mental illness, thus it's important to determine the eveningness personality among student population to avoid serious complications in later age.
2019 年，COVID-19 爆发成为一场严重的大流行病，数十亿人感染。为了遏制病毒的传播，采取了各种预防措施，如保持社交距离、公共封锁、卫生和关闭学校和学院。许多学院开始开设在线课程，以恢复教学大纲并完成课程。这些晚上的在线课程导致睡眠延迟、长期使用手机/电脑以及睡眠模式紊乱。
本研究旨在确定 COVID-19 在线课程对早晚人格的影响，并将其与不同年龄组、性别和体重指数进行比较。
采用聚类抽样法从 1153 名成人大学生中抽取受试者，根据选择标准选择 897 名受试者，并通过邮件、社交媒体或通过研究人员直接访谈，向他们发送包含 Morningness-eveningness Questionnaire 和人口统计学及人体测量数据的在线调查。
897 名参与者的平均得分为 56.7，表明中间型早晚人格类型。在比较不同组时，年龄最小的组（18-20 岁）得分 4.23%（平均=46.7），女性受试者得分 6.13%（平均=58.1），体重过轻的 2.67%（平均=59.2）和超重组得分 2.89%（平均=59.7）表明明确的晚睡型。在 897 名被收集的人群样本中，有 8.13%的受试者出现明确的晚睡型，14.93%有中度晚睡型，17.38%处于中间类别，22.4%有中度早起型，37.11%有明确的早起型。
具有晚睡人格的受试者患精神疾病的风险较高，因此确定学生群体中的晚睡人格对于避免晚年出现严重并发症很重要。
