Sleep disturbances and stress are common among postgraduate medical students, adversely affect their physical and mental health, academic performance, and patient care. However, the existing evidence does not provide a comprehensive understanding of sleep pattern of medical students in India. We studied sleep pattern and associated factors of clinical medical postgraduate students in Kerala state of India.
This cross-sectional study assessed sleep patterns, lifestyle behaviors, and stress levels among 150 postgraduate medical students (aged between 25 and 44 years) from four medical institutions (one government and three private) in Kerala, India. Data were collected using a pretested structured questionnaire. Questions regarding socio-demographics, work pattern and lifestyle factors were also included. We used Pittsburgh Sleep Quality Index (PSQI) to evaluate sleep quality, and the Perceived Stress Scale-10 (PSS-10) to measure stress levels. Both bivariate and multivariate analysis were performed.
The prevalence of poor sleep quality was 62.7% (95% confidence interval (CI): 54.4-70.4%), based on the PSQI. Stress levels, measured by the PSS-10, reported that 10.7% (95% CI: 6.2-16.7%) had severe stress. Medical specializations, lack of exercise, family relationship challenges, social anxiety, and severe stress were significantly associated with poor sleep. Those who were having severe stress were more likely to report poor sleep quality compared to their counterparts (adjusted odds ratio (AOR):11.61, CI:1.35-99.39). Medical post graduates were more likely to report poor sleep quality compared to the surgical specialty (AOR: 2.27, CI:1.06-4.87).
Poor sleep quality and stress are highly prevalent among postgraduate medical students in Kerala. Better management of sleep hygiene by physicians is likely to increase the advice and treatment provided for their patients' sleep quality.
睡眠障碍和压力在医学研究生中很常见，会对他们的身心健康、学业成绩和患者护理产生不利影响。然而，现有证据并未全面了解印度医学生的睡眠模式。我们研究了印度喀拉拉邦临床医学研究生的睡眠模式及相关因素。
这项横断面研究评估了来自印度喀拉拉邦四所医疗机构（一所政府机构和三所私立机构）的150名医学研究生（年龄在25至44岁之间）的睡眠模式、生活方式行为和压力水平。数据通过预先测试的结构化问卷收集。问卷还包括社会人口统计学、工作模式和生活方式因素等问题。我们使用匹兹堡睡眠质量指数（PSQI）评估睡眠质量，使用感知压力量表-10（PSS-10）测量压力水平。进行了双变量和多变量分析。
根据PSQI，睡眠质量差的患病率为62.7%（95%置信区间（CI）：54.4 - 70.4%）。通过PSS-10测量的压力水平显示，10.7%（95%CI：6.2 - 16.7%）有严重压力。医学专业、缺乏运动、家庭关系挑战、社交焦虑和严重压力与睡眠质量差显著相关。与同龄人相比，有严重压力的人更有可能报告睡眠质量差（调整后的优势比（AOR）：11.61，CI：1.35 - 99.39）。与外科专业相比，医学研究生更有可能报告睡眠质量差（AOR：2.27，CI：1.06 - 4.87）。
喀拉拉邦医学研究生中睡眠质量差和压力普遍存在。医生更好地管理睡眠卫生可能会增加为患者睡眠质量提供的建议和治疗。
