Upon arrival, immigrant populations in Canada tend to present less allergies than their Canadian-born counterparts, but prevalence increases with time, a national study finds. However, exposing them to ethnic foods and cultural practices that they were accustomed to may help reduce allergies in this population, according to the researchers.
“There is no definitive answer as to the cause(s) of the definitely noted increase in allergies in immigrant populations when they move to Western countries such as Canada. However, the pattern is real and needs to be analyzed”, says Dr. David Fischer, President of the Canadian Society of Allergy and Clinical Immunology (CSACI).
As first-generation immigrants to Canada, Dr. Hind Sbihi (picture below), Research Associate at the University of British Columbia, and Jiayun Angela Yao, PhD candidate at the same institution, became intrigued by allergy rates among newcomers and conducted a study to understand the role that genetics and environmental factors play in the development of non-food allergies, such as hay fever.
The researchers explain that in the past decade, the media, public and researchers have mainly focused on food allergies “It’s critical to raise awareness for non-food allergies given their high prevalence in our population, and posing a big burden to our health care system,” they add.
Canada has some of the highest allergy rates
This is particularly true because Canada has some of the highest allergy rates in the world. According to the American Academy of Allergy Asthma & Immunology, approximately 10-30% of the global population has hay fever. While in the United States roughly 7.8% of people 18 and over has this allergy, almost 20% of the population in Canada is affected by it. Considering these statistics, Sbihi and Yao wanted to understand if immigrants in the country would also display an increase in allergies.
“Our study highlighted the unique opportunity to investigate allergies in migrant populations, who are going through a natural experiment, in which the environment around them changes dramatically in a relatively short period of time,” they explain.
To conduct the study, the scholars used the data collected in the Canadian Community Health Survey, which gathered information about the health status, lifestyle habits and basic demographics of a large and representative sample of Canadians. In the survey, respondents were asked whether they had non-food allergies – diagnosed by a physician-, and whether they were immigrants to Canada and if so, their time since arrival. “We took the responses to these questions, and assessed the statistical association between non-food allergies and immigration status”, they say.
Following this method, the study found that only 14.3% immigrants who had lived in Canada for less than 10 years had non-food allergies, while the rates for immigrants over 10 years and non-immigrants were 23.9% and 29.6%, respectively.
These results suggest that environmental factors, such as pollution, levels of sanitization and dietary choices, carry more weight in the development of allergic conditions in Canada, Dr. Fischer explains, while Dr. Sbihi and Yao add that more research is needed to pinpoint what those factors are, and to better understand how allergies arise by country of origin.
They also highlight the need for undertaking multicultural strategies to improve newcomers’ health.
Ethnic foods may help
Dr. Sbihi and Yao add that it is also important to understand that allergies are symptoms of a loss of internal balance that results from a dysfunction of the immune system. “Providing immigrants with means to access food or cultural practice that are ethnically-friendly may help them transition smoothly into the new environment without perturbing their natural balance,” they suggest.
“Our best hope to curb the increasing trend in allergic disorders is to prevent it. Prevention can only happen when there is a good understanding of risk factors that come to play in the development of these disorders.” For these reasons, they suggest that raising awareness among health practitioners about the link between immigration, environment and allergies might help in their patients’ management.
“The main role for medical practitioners is to work with patients to recognize if they have allergies, to manage them acutely with their patients and if necessary refer them allergist if there is some doubt about the diagnosis or for more definitive management,” says Dr. Fischer.

Female genital mutilation (FGM) comprises of all procedures involving partial or total removal of the female external genitalia such as the labia majora, labia minora, clitoris and other injuries to the female genitalia for non-medical reasons as defined by the World Health Organization (WHO).
Proponents of this act often engage in these behaviors to adhere to and preserve an ongoing cultural tradition that failed to take into consideration the dignity, physical trauma, emotional trauma, and human rights of young girls and women.
In a recent article titled SALWACE’s “imitated not mutilated” Campaign, the author/s referred to Bondo (a society for the performance of FGM) as “the recognition of adult women to choose what they want to do with their own bodies.” The author/s further describes the act of FGM as “labiaplasty” and “clitoroplexy” and other forms of “so-called female genital cosmetic surgeries.”

ONE of the biggest sources of conflict between South Asian couples is the perceived over-involvement of in-laws. This belief that in-laws are “meddling” in the relationship is a perception that both men and women alike seem to feel.
In the book “Multicultural Couple Therapy,” Mudita Rastogi notes that in her counselling work with South Asian couples in the United States, it was rare for the couples to not mention in-law problems, and that it was common for them to cite the in-laws as the main source of the relationship problem. Women typically mentioned feeling judged or persecuted by in-laws, while men felt in-laws meddled in their relationship with their spouse.

I was born at the Vavuniya General Hospital in the winter of 1988, in a town that is often referred to as the gateway to the northern Vanni region. As so many other families before us, we fled Sri Lanka during the civil war, amid death, destruction and uncertainty.
We arrived in Scarborough, Canada, in the early 90’s, in what would become the single largest Sri Lankan Tamil diaspora community outside of South Asia. I grew up speaking Tanglish (a blend of Tamil and English), eating string hoppers and spaghetti, and listening to A.R. Rahman and the Backstreet Boys.
In short, I am a ‘third culture’ kid, a blend of the home we left behind in Jaffna and the home we worked hard to create in Canada. So as a Canadian medical student when I was presented with the opportunity to spend several weeks training in any field and in any country around the world, the natural choice for me was to go “back home”.
Having spent over two decades away, I didn’t quite know what “back home” would mean on this first visit back. After months of phone calls, emails and planning, at the end of June, I arrived at the Jaffna Teaching Hospital, ready to start my five weeks of electives in internal medicine and general surgery. Unsurprisingly, I spent the first few days overwhelmed by the experience.
I have been volunteering, working, and learning in hospitals for most of my life. For most, hospitals are places that cause anxiety and stress, but for me, they are often a place of familiarity and comfort, somewhere where I feel engaged and useful. Despite years in this environment, the Jaffna Teaching Hospital felt foreign to me. The wards, the equipment, the staff uniforms, the very rhythm of the place was completely alien.
The most obvious difference was that everything was done by hand. There was not a single computer in sight. Having worked in a health system that is increasingly digital, this was a big change for me. I also soon discovered that patient records are not kept locked away in a filing cabinet at the clinic or hospital.
Rather, the patients themselves carry their clinic books, lab reports and even MRI scans to each appointment with them. While cumbersome and running the risk of losing documents, this system gives full autonomy to patients over their personal health records and also allows for the mobility of those records from one site to the next.
Despite (or perhaps because of) this system, the consultants (in Canada, we call them “attendings”) are able to see a massive case load in a very short period of time. This was most obvious on clinic days where upwards of 40 patients were assessed, treated, and dismissed and/or given a date for follow up, all within the span of two to three hours. It’s a whirlwind of papers shuffling, names being called, patients shifting in and out of the examination rooms, and notes hurriedly scrawled into clinic books.
I was equally stunned the first time I stepped into the casualty theatre – a carryover, it seemed, from Sri Lanka’s civil war, when trauma patients would flood into the hospital every day. Two tables, with one anesthetist each, for procedures that require general anesthesia.
All other procedures were conducted under local anesthesia on stretchers flying in and out of the large operating theatre. And, at the centre of it all, a group of dedicated and talented registrars and surgeons operate on everything from in-grown toenails causing infection to inguinal hernias, all using proper aseptic and clean protocols.
As a student, it was incredible to move from one table to the next and see so many different techniques and procedures happening simultaneously.
To me, this was controlled chaos. And this phrase echoed through my mind again and again as I proceeded through my weeks of training in Jaffna.
But beyond the differences, the language of medicine remained a constant thread to which I could hold. Human anatomy is the same the world over. And I marvelled as I watched my general surgery preceptor carefully reveal the facial nerves of a patient with a suspected tumour over his jaw bone. Like the branches of a tree, the branches of cranial nerve seven spread out across one half of the patient’s face, beginning to divide and separate just in front of the ear. It was like I was looking at a diagram in a textbook, the dissection down to the tumour was so precise and clean.
Acetaminophen too is the same all over the world. Whether we call it Panadol, Paracetamol or Tylenol, all three can be used to bring down a fever, all three can be used to relieve pain.
Though the medicine was fascinating, the most enriching aspects of this journey to Jaffna were the people that I had the privilege of meeting. From the patients, nursing staff, and fellow medical students to the registrars and consultants who served as my teachers and mentors, the people I met throughout my five weeks at the Jaffna Teaching Hospital made the experience unforgettable. They worked to bridge the cultural and linguistic gaps between us, provided thoughtful and insightful answers to my questions, and facilitated opportunities to practice clinical skills and learn new techniques.
What do you do, for example, with a patient with diabetic foot ulcers who can’t afford to buy shoes? Or having to label an otherwise medically fit patient as a “poor candidate” for kidney transplant because all such surgeries are done in the private sector and require hundreds of thousands of rupees to carry out?
I feel honoured to have had the opportunity to be a learner in Jaffna, and to speak to patients and practise medicine in my mother tongue, Tamil. I feel especially privileged to have met the dedicated, passionate, and talented physicians and medical students who propel medicine forward in Jaffna. Despite systemic barriers, low resources and a significantly complex patient population, they persevere, they innovate and they thrive.
As a teacher and friend from my general surgery elective in Jaffna so poignantly stated, “We have the resilience gene”. And I could not agree with him more.
