在美国儿童中观察到哮喘和过敏的高患病率和种族差异。本研究旨在确定儿童哮喘和过敏的危险因素，以及它们对过敏患病率种族差异的贡献。2008-2009年在德克萨斯州东北部1-8岁的儿童中进行了一项基于人群的横断面研究。本研究以家长问卷调查方式，透过托儿所、国小、诊所等方式，调查3766名儿童的健康状况、生活型态及家庭环境。在表明其种族的参与者中，255人是墨西哥裔美国人，178人是非洲裔美国人，969人是高加索人。非裔美国儿童的哮喘和湿疹患病率明显较高。白种人的鼻炎患病率最高。与墨西哥裔美国儿童相比，非洲裔美国儿童和白人儿童母乳喂养时间更短，更经常去日托中心，更经常在家中接触环境烟草烟雾。对于所有的孩子来说，在日托中心，暴露在潮湿的环境中和家中的烟草烟雾是哮喘和过敏的强危险因素。中央空调系统与墨西哥裔美国儿童喘息的患病率增加有关，而宠物与非洲裔美国人和白人儿童鼻炎的风险增加有关。白人儿童一般不比相对贫穷的墨西哥裔美国儿童健康。不同种族间哮喘和过敏症患病率的差异不能仅仅用社会经济地位来解释。生活方式和家庭环境暴露是德克萨斯州东北部儿童哮喘和过敏的重要危险因素。(C)2011 Elsevier B.

A high prevalence and racial disparities in asthma and allergy have been observed in American children. This study aimed to identify risk factors for asthma and allergy among children, and their contribution to racial disparities in allergy prevalence. A population-based cross-sectional study was carried out among children aged 1-8 years in Northeast Texas 2008-2009. The health conditions, life style and home environment of 3766 children were surveyed by parental questionnaires through e.g. daycares, elementary school, and medical clinics. Among participants who indicated their ethnicity, 255 were Mexican-Americans, 178 Afro-Americans and 969 Caucasians. Afro-American children had a significantly higher prevalence of asthma and eczema. Caucasian had the highest prevalence of rhinitis. Compared to Mexican-American children, Afro-American and Caucasian children were breast fed shorter time, more often went to day care center, had pets and environmental tobacco smoke exposure at home more often. For all children, being at a day care center, being exposed to dampness and environmental tobacco smoke at home were strong risk factors for asthma and allergy. Central air conditioning system was associated with an increased prevalence of wheeze among Mexican-American children, while pets were associated with an increased risk of rhinitis among Afro-American and Caucasian children. Caucasian children were generally not healthier than relatively poor Mexican-American children. Differences in the prevalence of asthma and allergy between races cannot be explained by socioeconomic status only. Life style and home environmental exposures are important risk factors for asthma and allergy in Northeast Texas children. (C) 2011 Elsevier B.V. All rights reserved.
