炎症性肠病流行病学研究进展

炎症性肠病(IBD)在不同地区、种族人群中的发病率有显著差异。近年来,IBD在既往高发病率的西方国家趋于稳定,而在亚洲国家呈逐渐增加趋势。IBD发病率在发展中国家逐年增高,可能与发展中国家经济高速发展、工业化进程加速有关,提示环境因素在IBD病因中扮演重要角色。目前国内关于IBD流行病学的研究处于起步阶段,有待联合更多医学中心进行以人群为基础的IBD流行病学研究。

Advances in Study on Epidemiology of Inflammatory Bowel Disease

Significant geographical and racial differences are seen in prevalence of inflammatory bowel disease （IBD）. The prevalence of IBD in western countries has the trend to be stabilized in recent years, while it has a trend to be increased rapidly in Asian countries which are formerly of low prevalence. The increase of prevalence of IBD in developing countries may be related to the rapid economic development and industrialization process. Environmental factors may play an important role in the pathogenesis of IBD. The epidemiological study on IBD in China is still at an early stage, and multicenter population-based epidemiological studies are urgently needed.
