摘要：Objectives. To examine the prevalence, exacerbations and management of asthma among Canada’s Aboriginal populations, and its relationship to socio-economic and geographic factors. Study design. Secondary analysis of a national cross-sectional questionnaire survey. Methods. Data were collected in 2000 and 2001 through a survey of Aboriginal children and adults residing on-and off-reserve as part of the 2001 Aboriginal People’s Survey (APS). The asthma related outcome variables — physician-diagnosed asthma, attack in past year and regular use of inhalants — were examined in relation to socio-economic and geographic factors such as income, education, housing and location of residence. Statistical analyses were based on weighted univariate and multivariate logistic regressions. Results. The results show variations in asthma diagnosis, attacks and inhalant use across geographic location, socio-economic and demographic characteristics. Geographic location was found to be significantly associated with asthma for both adults and children, with those living in the northern territories, on-reserve or rural locations being the least likely to be diagnosed. Geographic location and Aboriginal identity were also found to be significantly associated with asthma medication use. Conclusions. While these findings may suggest a “healthier” population in more remote locations, they alternatively point to a general pattern of under-diagnosis, potentially due to poor health care access, as is typical in more remote locations.
