Morningness-eveningness dimension in humans have been indicated to influence social behavior and individual health. The aim of the present study was to investigate the association of the morningness-eveningness dimension with behavioral and health aspects in a sample of undergraduate students. We assessed demographic data; the Pittsburgh Sleep Quality Index was used to evaluate sleep quality; the Morningness/Eveningness Questionnaire to determine morningness-eveningness, and the Self-Reporting Questionnaire to assess minor psychiatric disorders. A total of 372 students (66.7% females), on average 21.6 years old, participated in this study. Among them, 92.2% did not smoke, 58.9% engaged in physical activities, and 19.7% were night-shift workers. In regard to morningness-eveningness, 55.9% of the participants were intermediate between evening (39.5%) and morning (4.6%) types. Poor sleep quality (OR = 1.89), minor psychiatric disorders (OR = 1.92), and tobacco consumption (OR = 3.65) predominated among evening types. Evening types were predominantly males (OR = 1.72). This study suggests that evening types are more vulnerable to sleep and psychiatric disturbances, and tend to smoke more than morning types.
人类的晨型/晚型维度被表明会影响社交行为和个体健康。本研究的目的是调查晨型/晚型维度与大学生样本中行为和健康方面的关联。我们评估了人口统计学数据；使用匹兹堡睡眠质量指数评估睡眠质量；使用 Morningness/Eveningness Questionnaire 确定晨型/晚型，使用自我报告问卷评估轻微精神障碍。共有 372 名学生（66.7%为女性），平均年龄 21.6 岁，参加了这项研究。其中，92.2%的人不吸烟，58.9%的人参加体育活动，19.7%的人上夜班。关于晨型/晚型，55.9%的参与者处于晚型（39.5%）和晨型（4.6%）之间。睡眠质量差（OR=1.89）、轻微精神障碍（OR=1.92）和吸烟（OR=3.65）在晚型中更为普遍。晚型主要为男性（OR=1.72）。这项研究表明，晚型更容易出现睡眠和精神障碍，并且比晨型更倾向于吸烟。
