OBJECTIVES Shift work is defined as any irregular work schedule that extends beyond the usual 9 am to 5 pm time frame. Evidence from outside medicine suggests that it may be related to detrimental health outcomes. Our objective from this study is to evaluate sleep quality, health risks, and chronic diseases among post-graduate resident physicians who work on rotating shifts at a large tertiary health care center. STUDY DESIGN A self-reported questionnaire-based cross-sectional study. METHODS Sleep quality was assessed by Pittsburgh Sleep Quality Index (PSQI) while anxiety and depression were estimated through the four-item patient health questionnaire for anxiety and depression (PHQ-4). Associations between sleep quality and the following: Gender, PHQ-4 stage, year of residency, number of on-calls per month and subjective fatigue; memory impairment; and lack of concentration was investigated. RESULTS A total of 201 resident physicians participated in the study [60.7% males, median; IQR age: 27 years (26-29). More than one third of subjects were smokers, 41.3% were overweight, and 16.4% were obese. The majority (90%) reported poor sleep quality, 38.3% mild PHQ-4, 21.4% moderate PHQ-4, and 18.9% severe PHQ-4. Residents having six on-calls or more per month had significantly poorer sleep quality (p: 0.03), as well as higher anxiety and depression scores compared to their counterparts. Poor sleep quality was markedly associated with moderate PHQ-4, subjective fatigue, and lack of concentration (p: 0.026, 0.004 and 0.001, respectively). Subjective difficulty with concentration was reported in 86.6% of resident physicians and was significantly higher as the number of on-calls per month is 3 or more. Most residents report subjective fatigue (92.5%) while subjective memory impairment was prevalent in 68.7%. Irritable bowel syndrome was the most prevalent chronic disorder (13%), followed by heartburn or gastrointestinal ulcers and disc prolapse (6% and 3.5%, respectively). CONCLUSIONS Resident physicians have considerable risk for developing severe diseases. Our findings suggest that several modifications should be undertaken to enhance work facilities, limit working hours, and raise awareness among post-graduate resident physicians.

住院医师轮班工作中与睡眠质量和健康有关的问题：一项横断面研究。

目标轮班工作的定义是任何超出正常上午9点至下午5点时间范围的不定期工作计划。外部医学的证据表明，它可能与有害的健康结果有关。这项研究的目的是评估在大型三级医疗保健中心轮班工作的研究生住院医师中的睡眠质量，健康风险和慢性疾病。研究设计基于自我报告的基于问卷的横断面研究。方法采用匹兹堡睡眠质量指数（PSQI）评估睡眠质量，并通过四项患者健康问卷调查焦虑和抑郁（PHQ-4）评估焦虑和抑郁。睡眠质量与以下各项之间的关联：性别，PHQ-4阶段，居住年限，每月待命次数和主观疲劳；记忆力减退; 和缺乏集中力进行了调查。结果共有201位住院医师参与了该研究[男性比例为60.7％，中位数；男性为60.7％。IQR年龄：27岁（26-29）。超过三分之一的受试者是吸烟者，超重的占41.3％，肥胖的占16.4％。大多数（90％）的人报告睡眠质量差，轻度的PHQ-4为38.3％，中度的PHQ-4为21.4％，重度的PHQ-4为18.9％。与他们的同龄人相比，每月有6次以上通话的居民的睡眠质量明显较差（p：0.03），并且焦虑和抑郁评分更高。睡眠质量差与中度PHQ-4，主观疲劳和注意力不集中显着相关（分别为p：0.026、0.004和0.001）。据报道有86人主观集中注意力困难。有6％的为住院医师，并且每月的通话次数为3个或更多，因此明显更高。大多数居民报告主观疲劳（92.5％），而主观记忆障碍占68.7％。肠易激综合症是最普遍的慢性疾病（13％），其次是胃灼热或胃肠道溃疡和椎间盘脱出（分别为6％和3.5％）。结论住院医师有发展严重疾病的巨大风险。我们的研究结果表明，应进行一些修改以增强工作设施，限制工作时间并提高研究生住院医师的认识。其次是胃灼热或胃肠道溃疡和椎间盘脱出（分别为6％和3.5％）。结论住院医师有发展严重疾病的巨大风险。我们的研究结果表明，应进行一些修改以增强工作设施，限制工作时间并提高研究生住院医师的认识。其次是胃灼热或胃肠道溃疡和椎间盘脱出（分别为6％和3.5％）。结论住院医师有发展严重疾病的巨大风险。我们的研究结果表明，应进行一些修改以增强工作设施，限制工作时间并提高研究生住院医师的认识。
