This paper combines multiple cross-sections of data drawn from the National Population Health Survey and Canadian Community Health Survey to confirm the existence of the ‘healthy immigrant effect’, specifically that immigrants are in relatively better health on arrival in Canada compared to native-born Canadians, and that immigrant health converges with years in Canada to native-born levels. The paper finds robust evidence that the healthy immigrant effect is present for the incidence of chronic conditions for both men and women, and results in relatively slow convergence to native-born levels. There is only weak evidence in terms of self-assessed health status. The inclusion of controls for region of origin and year of arrival does not account for the observed effects, although region of origin is an important determinants of immigrant health. The paper then considers some alternative explanations for the observed differences, and support is found for the idea that the healthy immigrant effect reflects convergence in physical health rather than convergence in screening and detection of existing health problems.

Abstract: Immigrants in Canada constitute approximately 20% of the total population and will continue to account for a significant portion of the country''s population in the future. Accordingly, a growing body of research has focused on examining the disparity in health status between the increasing foreign-born and the Canadian-born populations. The healthy immigrant effect, in particular, acknowledges that immigrants have better health status than their Canadian-born counterparts upon arrival in the country. However, studies have shown that over time the health of immigrants declines to a level on par with the Canadian-born population. There is much speculation as to the reasons for this decline including acculturation (i.e., uptake of unhealthy lifestyles) and a lack of access to health care. Yet, there have been few studies to examine possible reasons for potential declines in health, especially from the perspective of immigrants themselves. This study is one of the first to qualitatively examine perceived changes in health status and reasons for health status change among immigrants. The paper presents the results of 23 in-depth interviews with adults with recent (less than 3 years of residency), mid-term (3–10 years), and long-term (more than 10 years) immigrants living in the Greater Toronto Area. The results reveal that the majority of the participants believed their health had remained stable or even improved over time due to improved living standards and lifestyle behaviours in Canada. Those who perceived their health to have worsened over time attributed the change to the stress associated with migration, and the aging process rather than the adoption of an unhealthy lifestyle. Additionally, while the vast majority of participants reported improved access to resources upon migration, there were mixed reviews in terms of how beneficial these resources were or could be for health. The findings highlight the need for research to incorporate mental health into studies on changing immigrant health status and to focus on those factors contributing to high levels of stress among more recent immigrants.
