特应性皮炎的流行病学特征

Epidemiological Features of Atopic Dermatitis

特应性皮炎(atopic dermatitis,AD)是一种慢性复发性、炎症性皮肤疾病,好发于婴幼儿和青少年,可延续至成人期或成人发作。AD发病情况不同国家、不同地区报道不一,但研究表明,其发病的总体趋势是上升的,给家庭、经济和社会带来负担。了解AD的流行病学特征及其相关因素,对于其致病因素和发病机制的探讨,以及在社会层面建立合适的应对措施具有重要意义。本文对近年来AD的流行病学特征总结综述如下。

Atopic dermatitis is a common,chronic relapsing,inflammatory skin disorder that usually occurs in infants and children but can also start or persist in adulthood. The prevalence of atopic dermatitis（ AD） is vary from different countries and districts. According to the existing literatures,the prevalence shows arising tendency overall. AD lowers the quality of life in the affected families and also increases economic burden of the society. Therefore,it is necessary to assess the prevalence and other epidemiologicalfeatures to assist with the exploration of the precise etiology and pathogenesis of the disease,and establish a proper strategy for management at the society level. This paper reviews some progress of atopic dermatitis in the epidemiological profiles.
