We conducted a nationwide Canadian telephone survey on food allergy prevalence between February 2016 and January 2017, targeting vulnerable populations (New, Indigenous, and lower-income Canadians). To examine the independent effect of demographic characteristics on food allergy. Canadian households with vulnerable populations were targeted using Canadian Census data and the household respondent reported whether each household member had a perceived (self-reported) or probable (self-report of a convincing history or physician diagnosis) food allergy. The association between perceived and probable food allergy and demographic characteristics was assessed through weighted multivariable random effects logistic regressions. Children, females, Canadian-born participants, adults with post-secondary education, and those residing in smaller households were more likely to report perceived or probable food allergy. Although immigrant parents self-reported less food allergy, Canadian-born children of Southeast/East Asian immigrant versus other immigrant or Canadian-born parents reported more food allergy. We have demonstrated clear associations between demographic characteristics and food allergy, which may provide important clues to the environmental determinants of food allergy.

加拿大全国研究中与食物过敏相关的人口统计学特征

我们在 2016 年 2 月至 2017 年 1 月期间针对弱势人群（新加拿大人、原住民和低收入加拿大人）开展了一项全国性的加拿大食物过敏流行电话调查。检查人口统计学特征对食物过敏的独立影响。使用加拿大人口普查数据将具有弱势群体的加拿大家庭作为目标，家庭受访者报告每个家庭成员是否有感知（自我报告）或可能（令人信服的病史或医生诊断的自我报告）食物过敏。通过加权多变量随机效应逻辑回归评估感知和可能的食物过敏与人口统计学特征之间的关联。儿童、女性、加拿大出生的参与者、受过高等教育的成年人，居住在较小家庭中的人更有可能报告感知或可能的食物过敏。尽管移民父母自我报告的食物过敏较少，但与其他移民或加拿大出生的父母相比，东南亚/东亚移民的加拿大出生的孩子报告的食物过敏更多。我们已经证明人口统计学特征与食物过敏之间存在明显关联，这可能为食物过敏的环境决定因素提供重要线索。
