National study finds fewer food allergies among new immigrants and Canadians with low education

 

The study, Surveying Prevalence of Food Allergy in All Canadian Environments (SPAACE), was published in September in the Journal of Allergy and Clinical Immunology: In Practice. It concluded that Canadians with lower education and new Canadians (individuals who immigrated to Canada within the last 10 years) have fewer food allergies than the general population. The study also found that there were no differences in the prevalence of food allergy according to income or Aboriginal status. 

 

The research was conducted by a team of AllerGen investigators and led by Ann Clarke, a professor in the Department of Medicine at the University of Calgary, and Susan Elliott, a professor in the Department of Geography and Environmental Management at the University of Waterloo.

 

In a previous AllerGen-funded study, the authors found that 8% of Canadians self-report a food allergy and prevalence differs across socioeconomic groups and geographic regions.

 

The current study is based on data collected from 5,734 households, representing over 15,000 individuals from low income, immigrant and Aboriginal populations across Canada. The study measured food allergy prevalence as self-reported by respondents.

 

“This research enables us not only to better characterize the prevalence and experience of food allergy in Canada, but also to understand how the environment may influence its development,” says Lianne Soller, first author of the study.

 

The reasons for the lower prevalence of food allergy among vulnerable Canadians are not clear; this difference could be due to a range of factors that require further research, according to the authors. 

 

Although immigrants were less likely to experience food allergy, the odds of their self-reporting food allergy increased by 2% with each additional year of residence in Canada.

 

“These findings support the ‘healthy immigrant effect,’ which states that new Canadians tend to have a low prevalence of chronic conditions, but their health status worsens with time and eventually converges with that of the Canadian-born population,” says Clarke.

 

The study’s findings will help researchers to better understand the lived experiences of food allergies in vulnerable populations. The findings may also help to identify and address gaps in education, health care and public policy, and to ensure equal opportunity for all Canadians to seek and receive appropriate care related to food allergies.
