Introduction. Medicine is one of the most stressful fields of education because of its highly demanding professional and academic requirements. Psychological stress, anxiety, depression and sleep disturbances are highly prevalent in medical students. Methods. This cross-sectional study was undertaken at the Combined Military Hospital Lahore Medical College and the Institute of Dentistry in Lahore (CMH LMC), Pakistan. Students enrolled in all yearly courses for the Bachelor of Medicine and Bachelor of Surgery (MBBS) degree were included. The questionnaire consisted of four sections: (1) demographics (2) a table listing 34 potential stressors, (3) the 14-item Perceived Stress Scale (PSS-14), and (4) the Pittsburgh Quality of Sleep Index (PSQI). Logistic regression was run to identify associations between group of stressors, gender, year of study, student's background, stress and quality of sleep. Results. Total response rate was 93.9% (263/280 respondents returned the questionnaire). The mean (SD) PSS-14 score was 30 (6.97). Logistic regression analysis showed that cases of high-level stress were associated with year of study and academic-related stressors only. Univariate analysis identified 157 cases with high stress levels (59.7%). The mean (SD) PSQI score was 8.1 (3.12). According to PSQI score, 203/263 respondents (77%) were poor sleepers. Logistic regression showed that mean PSS-14 score was a significant predictor of PSQI score (OR 1.99, P < 0.05). Conclusion. We found a very high prevalence of academic stress and poor sleep quality among medical students. Many medical students reported using sedatives more than once a week. Academic stressors contributed significantly to stress and sleep disorders in medical students.
引言。医学是教育领域中压力最大的专业之一，因为它对专业和学术的要求极高。心理压力、焦虑、抑郁和睡眠障碍在医学生中非常普遍。
方法。这项横断面研究在巴基斯坦拉合尔军事总医院和拉合尔牙科学院（CMH LMC）进行。研究对象为所有攻读医学学士和外科学士（MBBS）学位的各年级学生。问卷包括四个部分：（1）人口统计学信息；（2）一个列出 34 种潜在应激源的表格；（3）14 项感知压力量表（PSS-14）；（4）匹兹堡睡眠质量指数（PSQI）。采用逻辑回归分析来确定应激源组、性别、学习年限、学生背景、压力和睡眠质量之间的关联。
结果。总应答率为 93.9%（263/280 名受访者返回问卷）。PSS-14 的平均（SD）得分为 30（6.97）。逻辑回归分析显示，高水平压力与学习年限和与学业相关的应激源有关。单变量分析发现 157 例压力水平高的病例（59.7%）。PSQI 的平均（SD）得分为 8.1（3.12）。根据 PSQI 评分，263 名受访者中有 203 名（77%）睡眠质量差。逻辑回归显示，平均 PSS-14 评分是 PSQI 评分的显著预测因子（OR 1.99，P<0.05）。
结论。我们发现医学生的学业压力和睡眠质量差的现象非常普遍。许多医学生报告每周使用镇静剂超过一次。学业应激源对医学生的压力和睡眠障碍有显著影响。
