Few studies have investigated the factors associated with asthma in young Aboriginal children.
To characterize the association of demographic, environmental and early life factors with asthma in young Aboriginal children in Canada.
The 2006 Aboriginal Children's Survey was conducted among off-reserve Aboriginal children zero to six years of age to obtain information on Aboriginal children's development and well-being. The prevalence of asthma in Aboriginal children was obtained from the parental report of asthma as diagnosed by a health care professional.
The prevalence of reported asthma among off-reserve Aboriginal children zero to six years of age (n=14,170) was 9.4%. Asthma prevalence in both exclusively breastfed children (6.8%) and ever but not exclusively breastfed children (9.0%) was significantly lower than that in nonbreastfed children (11.0%). In the multiple logistic regression analysis, exclusive breastfeeding was protective of asthma compared with nonbreastfeeding (OR 0.59 [95% CI 0.44 to 0.78]). Older age groups, male sex, having two or more older siblings, low birth weight, day care attendance and ear infection were significant risk factors for asthma.
The prevalence of asthma among young Aboriginal children zero to six years of age living off reserve was slightly lower than that reported for all other Canadian children. Breastfeeding, especially exclusively breastfeeding, was protective of asthma in Aboriginal children, which is consistent with what has been observed in non-Aboriginal children in Canada. Public health interventions intended for reducing asthma incidence in young Aboriginal children should include breastfeeding promotion programs.
很少有研究调查与年轻的原住民儿童哮喘相关的因素。
描述与加拿大年轻原住民儿童哮喘相关的人口统计学、环境和生命早期因素。
2006 年在保留地外的原住民儿童中进行了“原住民儿童调查”，以获取有关儿童发育和健康状况的信息。通过父母报告由医疗保健专业人员诊断的哮喘，获得原住民儿童哮喘的患病率。
零至六岁保留地外的原住民儿童（n=14170）报告的哮喘患病率为 9.4%。纯母乳喂养儿童（6.8%）和曾经母乳喂养但非纯母乳喂养儿童（9.0%）的哮喘患病率明显低于非母乳喂养儿童（11.0%）。在多因素逻辑回归分析中，与非母乳喂养相比，纯母乳喂养对哮喘具有保护作用（OR 0.59 [95%CI 0.44 至 0.78]）。年龄较大、男性、有两个或更多年长的兄弟姐妹、低出生体重、日托和耳部感染是哮喘的显著危险因素。
生活在保留地外的零至六岁的年轻原住民儿童的哮喘患病率略低于所有其他加拿大儿童的报告。母乳喂养，特别是纯母乳喂养，对原住民儿童的哮喘具有保护作用，这与加拿大非原住民儿童的观察结果一致。旨在降低年轻原住民儿童哮喘发病率的公共卫生干预措施应包括促进母乳喂养计划。
