【摘要】 目的 调查医学生生物节律与抑郁、焦虑及压力的关系，为改善医学生心理健康状况提供依据。方法采用分层整群抽样和自填问卷的方式，选取某医学院共594名学生为研究对象，采用抑郁-焦虑-压力自评量表、清晨型-夜晚型量表、大学生健康生活方式量表中运动节律量表和青少年生物节律紊乱评定问卷中饮食节律量表评定医学生生物节律及心理健康状况。结果 单因素分析表明：学习负担、宿舍同学睡眠作息影响程度及睡眠、运动、饮食节律均影响医学生抑郁、焦虑与压力；是否为独生子女、在校期间每月生活费影响焦虑；母亲受教育程度影响压力（P均<0.05）。二元logistic回归分析显示：睡眠-觉醒昼夜节律为中间型学生不易有焦虑、压力倾向；清晨型不易有焦虑倾向；运动高得分者不易有抑郁倾向；饮食高得分者不易有抑郁、焦虑和压力倾向（P均<0.05）。结论 医学生抑郁、焦虑和压力倾向检出率较高，生物节律越规律，其检出率越低，应采用合理方式促进医学生身心健康全面发展。更多还原

【Abstract】 Objective This study investigated the relationships among biological rhythm and depression, anxiety,and stress in medical college students, to provide evidence for improving mental health among medical college students.Methods A total of 594 students from a medical college underwent stratified cluster sampling and a self-reported questionnaire study. The students’ biological rhythm and mental health status were evaluated according to a depression-anxietystress self-rating scale, early-evening scale, exercise rhythm scale in the Healthy Lifestyle Scale for College Students, and diet rhythm scale in the Adolescent Biorhythm Disorder Assessment Questionnaire.Results Univariate analysis indicated that study burden, the degree of influence of dormitory students’ sleep and rest, sleep rhythm, exercise, and diet affected depression, anxiety, and stress among medical college students. Being an only child and monthly living expenses during school were found to affect anxiety; moreover, maternal education level was found to influence stress(all P <0.05). Binary logistic regression analysis indicated that students with an intermediate sleep-wake circadian rhythm were not prone to anxiety and stress. The early morning type was not prone to anxiety. Students who scored higher in exercise were less prone to depression. Students with higher diet scores were less prone to depression, anxiety, and stress(all P <0.05).Conclusions The detection rates of depression, anxiety, and stress tendency among medical students were high, and a more regular biological rhythm was associated with lower detection rates. Reasonable measures should be adopted to achieve comprehensive promotion of physical and mental health among medical college students.更多还原
