“…Similar to the results observed in Aboriginal children, asthma prevalence in Aboriginal adults increased from 11.6% in the 2001 APS to 14.0% in the present study using the 2006 APS (7). An increase of asthma-related emergency room and physician office visits was also reported in studies based in Alberta and Saskatchewan (3,5,6), where the Aboriginal population was more likely to be hospitalized and to have emergency room and physician office visits than the nonAboriginal population (6). …”

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.

“…Wheezing rates rose during the study in the placebo group, likely because of increased exposure to respiratory viruses during mid‐winter, when rates of viral infection peak in the arctic (Singleton et al., 2006). Asthma and atopy, including allergy to house dust‐mites, are not common in Inuit children (Gao et al., 2008; Hemmelgarn and Ernst, 1997) and these houses have negligible concentrations of dust‐mite allergens (Hemmelgarn and Ernst, 1997; Kovesi et al., 2006), so a potential reduction in dust‐mite levels cannot explain our results. In the case of influenza virus, aerosol, rather than droplet or direct contact spread, is more likely to lead to lower respiratory tract infection (Salgado et al., 2002).…”

Heat recovery ventilators prevent respiratory disorders in Inuit children

Reduced ventilation is common in the houses of Inuit children in arctic Canada, and is associated with an increased risk of respiratory infection. Installation of HRV brings indoor carbon dioxide concentration, as a marker of adequate ventilation, to within recommended concentrations, although relative humidity is also reduced. Installation of HRV is associated with improvements in indoor air quality, and a reduced risk of wheezing and rhinitis not associated with cold air exposure in young Inuit children. Further research is required to explore traditional Inuit cultural attitudes about air movement in dwellings.

“…Finally, both asthma and food allergies are related atopic conditions, and although there has yet to be an established causal link between the two, the risks of having both are well known (Wang and Liu 2011). Comorbidity of general allergies and asthma has also been reported in previous research on northern Aboriginal children in Canada (Gao et al 2008b).…”

“…One exception is a recent study by MacMillan and colleagues () which reveals that allergies (13 percent) and asthma (12 percent) represent the second and third most frequently reported health conditions among First Nations and Inuit children behind ear conditions (15 percent). Furthermore, while asthma has received the most research attention to this point (Sin et al ; Gao et al ; Crighton et al ), there is some indication that allergies affect Aboriginal children at a higher rate than the general population (Lix et al ; Smylie and Adomako ). However, food allergies tend to be merged with other allergies (e.g., environmental), or other chronic conditions, making it difficult to tease out prevalence.…”

Food allergies have emerged as an important public health risk in many countries, Canada included, affecting children at a disproportionate rate. However, we know very little about food allergies among Aboriginal children in Canada, who are often characterized as representing a particularly vulnerable population with respect to health and life conditions more generally. Our objective was to address this gap by exploring the prevalence and management of food allergies in this population. Data from the 2006 Aboriginal Children's Survey were used for this analysis. Descriptive analyses were undertaken to determine the prevalence of diagnosed food allergies among off-reserve Aboriginal children, and logistic regression was used to explore factors associated with diagnosis, and the determinants of receiving treatment. Estimates of prevalence (2.9%) appear lower than the general population in Canada. Controlling for demographic and socioeconomic factors, co-morbidity of asthma and access to family physicians and specialists (e.g., allergists) most strongly predicted both prevalence and treatment. Lower prevalence rates suggest either truly lower rates or lower rates of detection in this population. Access to treatment appears most significant for diagnosis and treatment for this population, raising important directions for future research addressing disparities in the management of food allergies among Aboriginal children. Diagnostic et traitement des allergies alimentaires chez les enfants autochtones hors réserve au CanadaLes allergies alimentaires ont fait leur apparition comme un risque majeur de santé publique dans nombreux pays, y compris le Canada; et les enfants les subissent d'une manière disproportionnée. Cependant, nous en connaissons très peu sur les allergies alimentaires chez les enfants autochtones au Canada, eux qui constituent une population particulièrement vulnérable tant au niveau de la santé que des conditions de vie en général. Nous nous sommes donc employés à combler cette lacune en examinant la prévalence et la gestion des allergies alimentaires au sein de cette population. Cette étude s'est appuyée sur les données tirées de l'Enquête sur les enfants autochtones de 2006. Des analyses descriptives ont permis d'estimer la prévalence des allergies alimentaires diagnostiquées parmi des enfants autochtones hors réserve et une régression logistique a été effectuée pour analyser les facteurs associés au diagnostic et ceux déterminant le commencement d'un traitement. La prévalence estimée (2,9%) parait moins élevée que dans l'ensemble de la population canadienne. Le contrôle des variables indique que les facteurs démographiques et socioéconomi-ques, la présence de la comorbidité asthmatique et l'accès à des médecins de famille et des spécialistes (par exemple, des allergologues) sont les meilleurs prédicteurs de la prévalence et du traitement. Les faibles taux de prévalence indiquent soit des taux réellement inférieurs, soit des taux de détection plus faibles dans cette population. L'accès au traitement...
