Newcomer children show lower rates of emergency department use for non‑urgent conditions, study finds
Refugee and immigrant children are less likely to visit the emergency department for minor illnesses compared to children born in Ontario.
Poverty is one of the strongest determinants of health, regardless of immigration status, according to a new study from the Institute for Clinical Evaluative Sciences (ICES) and the University of Toronto.
“What our study found was despite the healthy immigrant effect, those living in the most deprived areas, irrespective of immigration status had the highest mortality rates,” says Laura Rosella, the study’s lead author, ICES scientist and assistant professor of epidemiology at the University of Toronto’s Dalla Lana School of Public Health.
The “healthy immigrant effect” refers to a trend where new immigrants to Canada are healthier than the Canadian population, but over time and successive generations, their health as well as that of their children and grandchildren tends to decline.
In the study, published today in Journal of Epidemiology & Community Health, the researchers examined data representing all deaths in Ontario from 2002 to 2012 to analyze how socioeconomic factors impact mortality according to immigration status.
The study found:
- All-cause and premature mortality were about 60 per cent lower among immigrants compared to Canadian or long-term residents. Over the 10 year study period, this translated into 42,700 fewer deaths overall and 18,400 fewer premature deaths in immigrants compared to Canadian-born or long term residents.
- The average age at death for female and male immigrants was approximately six years younger than that of female and male long-term residents.
- In both immigrants and non-immigrants, those living in the most deprived areas had higher rates of all-cause and premature mortality, although immigrant mortality was lower across all levels.
- The advantage in all-cause and premature mortality among male immigrants over male long-term residents was slightly more pronounced than the advantage among female immigrants over female long-term residents.
“These findings support the need to better examine the factors that drive these inequalities to ensure equitable health for the totality of the population,” says Rosella, who is also a scientist at Public Health Ontario.
“Socioeconomic gradients in all-cause, premature and avoidable mortality among immigrants and long-term residents using linked death records in Ontario, Canada,” was published today in the Journal of Epidemiology & Community Health.

The Institute for Clinical Evaluative Sciences (ICES) is an independent, non-profit organization that uses population-based health information to produce knowledge on a broad range of healthcare issues. Our unbiased evidence provides measures of health system performance, a clearer understanding of the shifting healthcare needs of Ontarians, and a stimulus for discussion of practical solutions to optimize scarce resources. ICES knowledge is highly regarded in Canada and abroad, and is widely used by government, hospitals, planners, and practitioners to make decisions about care delivery and to develop policy.
