大学生睡眠问题与非自杀性自伤行为的关系

Relationship between sleep problems and non-suicidal self-injury behavior among college students

目的探讨大学生睡眠问题与非自杀性自伤行为(non-suicidal self-injury,NSSI)的关系,为大学生NSSI行为的预防和干预提供科学依据。方法采用随机整群抽样方法,选取广东省3所高校的11689名大学生作为研究对象,采用大学生心理健康状况调查问卷调查大学生的NSSI行为、睡眠问题、一般人口学特征、生活习惯和抑郁症状。结果大学生在过去1年内的NSSI行为报告率为7.8%。单因素Logistic回归分析显示,NSSI行为与工作日睡眠时间、周末睡眠时间、失眠、噩梦睡眠问题均有相关性(P值均<0.05);在控制年级、性别、父母教育水平、身体健康状况、家庭收入、吸烟、饮酒和抑郁症状后,多因素Logistic回归分析显示,周末较短的睡眠时间(<7 h/d)、失眠症状和频繁噩梦均能增加大学生NSSI行为的发生风险(OR=1.32~3.25,P值均<0.05),而工作日较长的睡眠时间(≥9 h/d)则与NSSI行为呈负相关(OR=0.60,P<0.05)。结论睡眠时间过短、失眠和噩梦是大学生NSSI行为的重要风险因素,加强对睡眠问题的干预和管理可减少自伤行为的发生。

Objective To explore the relationship between sleep problems and non-suicidal self-injury behavior in Chinese college students,and to provide scientific basis for the prevention and intervention of non-suicidal self-injury behavior. Methods A cross-sectional survey of 11 689 college students from three universities in Guangzhou were selected as the research subjects. A questionnaire survey of college students’ mental health was conducted to investigate non-suicidal self-injury behavior,sleep problems,demographic information,lifestyle,and depressive symptoms. Results In the past year,the prevalence rates of non-suicidal self-injury in college students was 7.8%. Univariate Logistic analysis showed that all sleep problems were associated with non-suicidal self-injury behavior( P<0.05). After controlling for potential confounders,including grade,gender,parents’ education level,health conditon,family income,smoking,drinking and depression,multivariate Logistic regression showed that shorter sleep time at weekend( <7 h/d),insomnia symptoms and frequent nightmares significantly increased the risk of non-suicidal self-injury behavior in college students( OR = 1.32-3.25,P<0.05),while longer sleep time at weekdays( ≥9 h/d) was an important protective factor( OR= 0.60,P<0.05). Conclusion These findings indicate that short sleep time,insomnia and nightmares are important risk factors for college students’ non-suicidal self-injury behavior. Intervention and management on sleep problems can effectively reduce the occurrence of self-injury behaviors.
