Abstract

Epidemiology is a fundamental discipline in medical research, as it examines the distribution and determinants of diseases within populations. To achieve this, it employs various research designs, which are broadly classified into observational and experimental studies. Observational studies include descriptive studies, such as case series and cross-sectional studies, as well as analytical studies, such as cohort and case-control studies, which assess associations between exposures and health outcomes. Experimental studies, particularly randomized controlled trials, establish causal relationships. The choice of study design depends on the research question, feasibility and available resources.

It is essential to understand their characteristics, the contexts in which they should be applied and the most common sources of bias to ensure the accurate interpretation of results.

儿科科学研究和出版方法。主要方法学设计

流行病学是医学研究中的一门基础学科，因为它研究人群中疾病的分布和决定因素。为了实现这一目标，它采用了各种研究设计，这些设计大致分为观察研究和实验研究。观察性研究包括描述性研究，如病例系列研究和横断面研究，以及分析性研究，如队列研究和病例对照研究，评估接触与健康结果之间的关系。实验研究，特别是随机对照试验，建立了因果关系。研究设计的选择取决于研究问题、可行性和可用资源。重要的是要了解它们的特点、应用它们的背景和最常见的偏见来源，以确保对结果的准确解释。
