Epidemiology of gastroesophageal reflux disease

胃食管反流病(gastroesophagealre flux disease,GERD)在西方国家是一种常见病,易反复发作,严重影响患者的生活质量,他是近年来医学研究的热点之一.亚太地区GERD患病率较低,但近年来流行病学调查显示其患病率有上升趋势.GERD的流行病学、发生发展的危险因素等方面存在诸多问题需进行研究.我们就此领域的研究及最新进展作一综述.

Gastroesophageal reflux disease（GERD）,a common disorder in Western society,is less seen in Asian countries,but there is an evidence that the incidence of GERD and its complications is rising.Many factors are believed to be responsible for the pathogenesis of GERD.In addition to some recognized factors,the role of other factors,such as obesity and Helicobacter pylori infection,in the pathogenesis of GERD is still unclear.Furthermore,GERD is believed to be associated with the development of many other diseases.This review summarizes the prevalence and risk factors of GERD and its complications.
