To investigate the relationship between common psychiatric disorders (CPDs) and sleep characteristics (evening chronotype, poor sleep quality and daytime sleepiness) among Thai college students.
A cross-sectional study was conducted among 2,970 undergraduate students in Thailand. Students were asked to complete a self-administered questionnaire that collected information about lifestyle and demographic characteristics. The Horne and Ostberg Morningness-Eveningness Questionnaire (MEQ), Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) were used to evaluate circadian preference, sleep quality and daytime sleepiness, respectively. The General Health Questionnaire-12 (GHQ-12) was used to evaluate presence of CPDs. Logistic regression models were used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) of CPDs in relation to the covariates of interest.
A total of 337 students were classified as having CPDs (11.2%; 95% CI 10.1-12.3%). Evening chronotype (OR = 3.35; 95% CI 2.09-5.37), poor sleep quality (OR = 4.89; 95% CI 3.66-6.54) and excessive daytime sleepiness (OR = 1.95; 95% CI 1.54-2.47) were statistically significantly associated with CPDs.
Our study demonstrated that CPDs are common among Thai college students. Further, evening chronotype, poor sleep quality and excessive daytime sleepiness were strongly associated with increased risk of CPDs. These findings highlight the importance of educating students and school administrators about the importance of sleep and their impact on mental health.
探讨泰国大学生常见精神障碍（CPDs）与睡眠特征（夜晚型生物钟类型、睡眠质量差和日间嗜睡）之间的关系。
对泰国2970名本科生进行了一项横断面研究。要求学生完成一份自填式问卷，收集有关生活方式和人口统计学特征的信息。分别使用霍恩和奥斯特伯格晨型-夜型问卷（MEQ）、匹兹堡睡眠质量指数（PSQI）和爱泼华嗜睡量表（ESS）来评估昼夜节律偏好、睡眠质量和日间嗜睡情况。使用一般健康问卷-12（GHQ-12）来评估CPDs的存在情况。采用逻辑回归模型估计CPDs与相关协变量的调整比值比（ORs）和95%置信区间（95% CIs）。
共有337名学生被归类为患有CPDs（11.2%；95% CI 10.1 - 12.3%）。夜晚型生物钟类型（OR = 3.35；95% CI 2.09 - 5.37）、睡眠质量差（OR = 4.89；95% CI 3.66 - 6.54）和日间过度嗜睡（OR = 1.95；95% CI 1.54 - 2.47）与CPDs在统计学上显著相关。
我们的研究表明CPDs在泰国大学生中很常见。此外，夜晚型生物钟类型、睡眠质量差和日间过度嗜睡与CPDs风险增加密切相关。这些发现凸显了向学生和学校管理人员宣传睡眠重要性及其对心理健康影响的重要性。
