摘要
   仅有少数研究对加拿大土著儿童的哮喘患病率进行了分析。本研究数据来自于2006年进行的土著人调查，旨在研究加拿大6～14岁土著儿童和15～64岁土著成人中的哮喘患病率和危险因素。哮喘患病率在儿童为14.3%，成人为14.0%。与北美印第安人和梅蒂斯人相比，有因纽特人血统的儿童和成人的哮喘患病率较低。与儿童哮喘相关的因素有：男性、过敏症、低出生体重、肥胖、居住条件较差和城市居民。在成人中，与哮喘相关的因素在土著人群中也存在差异，但年龄组、性别和城市居民在所有4个土著人群均与哮喘相关。与研究报道的加拿大人哮喘患病率相比，土著儿童的哮喘患病率较低，土著成人的哮喘患病率较高。不同土著加拿大人的哮喘患病率和危险因素也存在差异，可能与遗传因素和环境因素相关，这一点还需进行深入研究。

Prevalence and risk factors of asthma in off-reserve Aboriginal children and adults in Canada.

Chang HJ, Beach J, Senthilselvan A.

Abstract
Only a few studies have investigated asthma morbidity in Canadian Aboriginal children. In the present study, data from the 2006 Aboriginal Peoples Survey were used to determine the prevalence and risk factors for asthma in Canadian Aboriginal children six to 14 years of age and adults 15 to 64 years of age living off reserve. The prevalence of asthma was 14.3% in children and 14.0% in adults. Children and adults with Inuit ancestry had a significantly lower prevalence of asthma than those with North American Indian and Métis ancestries. Factors significantly associated with ever asthma in children included male sex, allergy, low birth weight, obesity, poor dwelling conditions and urban residence. In adults, factors associated with ever asthma varied among Aboriginal groups; however, age group, sex and urban residence were associated with ever asthma in all four Aboriginal groups. The prevalence of asthma was lower in Aboriginal children and higher in Aboriginal adults compared with that reported for the Canadian population. Variation in the prevalence of and risk factors for asthma among Aboriginal ancestry groups may be related to genetic and environmental factors that require further investigation.
