Introduction An understanding of epidemiology is fundamental for designing research and understanding evidence-based medicine (EBM). The purpose of our study was to determine the knowledge of epidemiology among postgraduate medical trainees. Methods We carried out a cross-sectional study from January 2017 to June 2017 at the Regional Centre Islamabad, College of Physicians and Surgeons Pakistan. About 204 postgraduate medical trainee were enrolled in the study after taking written consent. All of the participants were working as a postgraduate medical trainee in different hospitals of Rawalpindi and Islamabad. A self-designed structured questionnaire containing 20 multiple choice questions regarding knowledge of epidemiology was given to all the participants. Knowledge of epidemiology was measured and compared with gender, hospital, and previous history of research. Statistical Package for the Social Sciences (SPSS), version 21.0 (IBM, Armonk, NY) was used for data analysis. Results Out of 204 participants, 46.1% participants were males while 53.9% were females. The mean age of the participant was 28.5 ± 2.5. Majority fo the trainees (33.8%) were training in an Internal Medicine residency program. Most of the trainees (76%) had average knowledge of epidemiology while 18.6% of the trainees had good knowledge. Only 17.6% had some experience of research projects in the past, but this was not related to knowledge of epidemiology (p > 0.05). Conclusion Only 18.6% of the postgraduate trainees had good knowledge regarding epidemiology and 76% had average knowledge. This knowledge did not relate to their gender, hospital settings, and previous experience of conducting research proposals and articles.
引言
了解流行病学是设计研究和理解循证医学（EBM）的基础。我们研究的目的是确定医学研究生学员对流行病学的了解程度。
方法
2017年1月至2017年6月，我们在巴基斯坦伊斯兰堡地区中心、巴基斯坦内科医师与外科医师学院开展了一项横断面研究。在获得书面同意后，约204名医学研究生学员参与了该研究。所有参与者均在拉瓦尔品第和伊斯兰堡的不同医院担任医学研究生学员。我们向所有参与者发放了一份自行设计的结构化问卷，其中包含20道关于流行病学知识的多项选择题。对流行病学知识进行了测量，并与性别、医院以及既往研究经历进行了比较。使用社会科学统计软件包（SPSS）21.0版（IBM，纽约州阿蒙克）进行数据分析。
结果
在204名参与者中，46.1%为男性，53.9%为女性。参与者的平均年龄为28.5±2.5岁。大多数学员（33.8%）正在内科住院医师培训项目中接受培训。大多数学员（76%）对流行病学有一般了解，而18.6%的学员有良好的了解。过去只有17.6%的学员有一些研究项目经验，但这与流行病学知识无关（p>0.05）。
结论
只有18.6%的研究生学员对流行病学有良好的了解，76%的学员有一般了解。这种知识与他们的性别、医院环境以及以往撰写研究计划书和文章的经验无关。
