摘要:
目的 探讨专科生睡眠时间与负性情绪症状的关联, 为提高大学生心理健康水平提供参考。 方法 采用整群抽样的方法, 于2021年3月选取安徽省淮南市某专科院校2 524名大一学生为研究对象, 采用问卷调查一般人口学特征、睡眠时间、负性情绪症状等信息, 应用限制性立方样条和多因素Logistic回归模型分析专科生睡眠时间与负性情绪症状的关联。 结果 专科生中抑郁症状、焦虑症状、压力症状的检出率分别为19.4%(490名), 28.2%(713名), 9.9%(250名), 男生(24.3%, 34.0%, 19.1%)的负性情绪症状检出率高于女生(18.7%, 27.4%, 8.5%), 差异均有统计学意义(χ2值分别为5.81, 6.27, 36.23, P值均 < 0.01)。调整相关混杂因素后, 专科生睡眠时间与负性情绪症状呈非线性的剂量-反应关系。与参照组8~ < 9 h相比, 专科生学习日和周末的每天睡眠时间 < 7 h与抑郁和压力症状风险增加有关, < 8 h与焦虑症状风险增加有关; 与参照组 < 1 h相比, 专科生周末每天补充睡眠时间≥5 h与负性情绪症状风险增加有关(P值均 < 0.01)。 结论 专科生较短睡眠时间以及较长周末补充睡眠时间与负性情绪症状关联密切, 指导大学生合理安排睡眠时间有利于负性情绪问题的防控。 Abstract:Objective To explore the associations between sleep duration and negative emotions among junior college students, and to provide reference for mental health promotion among college students. Methods Cluster sampling method were used to select 2 524 freshmen from a college in Huainan, Anhui Province. Questionnaires were used to investigate general demographic characteristics, sleep timing, negative emotions and other information. The restricted cubic spline and multivariate Logistic regression were used to analyze the relationship between sleep duration and negative emotion among junior college students. Results The prevalence of depressive symptoms, anxiety symptoms, stress-associated symptoms were 19.41%(490), 28.2%(713), 9.9%(250) respectively.The prevalence of negative emotions was higher among boys(24.3%, 34.0%, 19.1%) than girls(18.7%, 27.4%, 8.5%). The differences between groups were statistically significant(P < 0.01). After adjusting for confounding factors, sleep duration and negative emotions showed a non-linear dose-response relationship. Compared with the reference group (8-<9 h), sleep duration < 7 h was significantly associated with an increased risk of depressive symptoms and stress symptoms, and < 8 h was associated with an increased risk of anxiety symptoms. The additional sleep time on weekends ≥5 h was associated with negative emotions compared with the reference group(< 1 h) (P < 0.01). Conclusion Short sleep duration and extra weekend sleep are associated with negative emotions. Reasonable sleep schedule among junior college students might be helpful for the prevention and control of negative emotions. -
