简介：抽动障碍是儿童期神经发育障碍，与精神共病和学业问题相关。估计抽动障碍的患病率和了解其流行病学比以前想象的要复杂得多。直到最近，抽动障碍还被认为是罕见的，但如今抽动被认为是最常见的运动障碍，0.2-46.3% 的学童在一生中经历过抽动。对不同患病率估计值的初步解释包括抽动症的多维性质、表现形式多样且异质性，以及不同流行病学方法和研究设计的使用。方法：文献回顾和分析与抽动障碍流行病学研究相关的方法学问题。结果：回顾了抽动障碍的流行病学研究，以及流行病学研究的主要要素，包括样本选择、病例确定策略、抽动障碍的定义以及合格人群的覆盖程度。讨论：为了提高抽动障碍流行病学研究的质量，提出了一些建议，包括但不限于审查抽动障碍的诊断标准，以及为继发性抽动障碍患者纳入新的抽动障碍类别。
INTRODUCTION: Tic disorders are neurodevelopmental disorders of childhood associated with psychiatric comorbidity and academic problems. Estimating the prevalence and understanding the epidemiology of tic disorders is more complex than was once thought. Until fairly recently, tic disorders were thought to be rare, but today tics are believed to be the most common movement disorder, with 0.2-46.3% of schoolchildren experiencing tics during their lifetime. Tentative explanations for differing prevalence estimates include the multidimensional nature of tics with a varied and heterogeneous presentation, and the use of different epidemiological methods and study designs.METHODS: Literature review and analysis of methodological issues pertinent to epidemiological studies of tic disorders.RESULTS: Epidemiological studies of tic disorders were reviewed, and the main elements of epidemiological studies, including sample selection, case ascertainment strategy, definition of tic disorders, and the degree of coverage of the eligible population (i.e., the response rate) were examined.DISCUSSION: In order to improve the quality of epidemiological studies of tic disorders, a number of recommendations were made, including but not limited to a review of the diagnostic criteria for tic disorders, and inclusion of new tic disorder categories for those with tics of secondary etiology.
