Immigrant children’s health declines rapidly after arrival in Canad

A healthy, happy future, free from poverty: This is the aspiration of many new immigrants and refugees to Canada and the United States. Leaving harsh conditions and food scarcity behind, they embrace the safety and relative affluence that North America offers.

Few would have imagined that migration would damage their family’s well-being and lead to rapid health decline.

Yet research studies over the past 15 years have found that immigrants arrive in better health than Canadians — with a lower incidence of chronic diseases such as heart disease, cancer and diabetes — but suffer a decline in their health as their time in Canada increases.

This decline applies to young children too. As a professor and a postdoctoral fellow in the School of Public Health and College of Pharmacy and Nutrition at the University of Saskatchewan, we recently conducted the first comprehensive research project in Canada examining the health of immigrant and refugee children after their arrival in the country.

This study, published in Applied Physiology, Nutrition and Metabolism, found several health concerns and nutritional deficiencies in many of these children.

Higher blood pressure, unhealthy cholesterol
Our study of 300 immigrant and refugee children in Saskatoon and Regina, Saskatchewan, found that these newcomer children often embrace a Western diet and sedentary lifestyle. Some parents are unaware of the dangers of overeating and the calories attached to the Western diet.

Overall, newcomer children were found to have borderline or elevated blood pressure— substantially higher than that of Canadian children.

Thirty-six per cent of the children in our study also had an inadequate intake of zinc, which is essential for growth and development.

Fifty-two per cent had unhealthy cholesterol levels, whereas just 35 per cent of Canadian children had similar levels. It is worth mentioning that increased stress is a known risk factor for high cholesterol.

Other research has found that some groups, such as South Asian immigrants — particularly women — are at a higher risk of developing high blood pressure the longer they reside in Canada.

Non-European newcomers also experience significant deterioration in how they rate their own health, and increase in body mass index (BMI) over time, compared to people who were born in Canada.

Poverty and dead-end jobs
Why this decline in health? Canada offers relatively abundant food, accessible health care and a standard of living that is one of the highest in the world, so the findings may appear counter-intuitive.

The answer lies both in the situations that immigrants and refugees have left behind, and the conditions they find when they get here.

Some immigrants find their pre-immigration dreams confounded by circumstance. They live in relative poverty, working dead-end jobs that fail to exploit their experience and potential. Some came to Canada as highly qualified professionals, optimistic about their prospects in a new country, but are unable to find meaningful, rewarding employment. Some who dreamed of a middle-class lifestyle struggle at the bottom of the economic pile due to language and educational barriers.

A diet of cheap, readily available junk food doesn’t help.

For many immigrant families, the stress of adjusting to life in Canada may contribute to deteriorating health. Many lose their social support network through migration. It can also be challenging to access culturally appropriate health care.

Living in survival mode
We spoke with numerous immigrants and health-care providers about newcomer health, diet and lifestyles. Many newcomers spoke of their aspirations to attain a good standard of living in Canada and the daily struggles they experienced to achieve this.

Some had become disillusioned with life in Canada because of their difficulties achieving the lifestyle they had expected, or aspired toward.
