Age and Gender Variations in Healthy Immigrant Effect: a Population Study of Immigrant Well-Being in Canada

The healthy immigrant effect (HIE) is the phenomenon in which immigrants show better health than their native-born counterparts but this healthier condition declines with length of residence. This study investigated whether (1) immigrants also show better adaptation than non-immigrants as well as better health, (2) length of residence affects their health and adaptation differently, and (3) differential outcomes are found for different age and gender groups. Utilizing the Canadian Community Health Survey (2011–2012) data, immigrants (N?=?17,555) and non-immigrants (N?=?103,579) were divided into adolescents (15–19 years old), adults (20–49), older adults (50–64), and seniors (65–74) to examine their subjective general and mental health, diagnosed chronic and psychological illnesses, and self-reported daily stress, life satisfaction and sense of belonging. After controlling for key demographics, HIE was found to be more robust in health than adaptation. In general, recent immigrants reported better health conditions than long-term immigrants; however, the two did not differ with daily stress or life satisfaction. The older adult immigrants were the only segment of the immigrant population who did not display HIE; within the immigrant population, working-aged long-term adult immigrants were those experiencing negative well-being in both health and adaptation compared to the same-aged recent immigrants. Regarding diagnosed psychological illnesses, immigrants yielded no difference by age, gender, or length of residence, indicating ‘reluctant’ views on seeking professional help for mental health were persistently held by both recent and long-immigrants. The findings suggest that health policy needs to take into consideration age-related life stages, and enhancement of mental health awareness for immigrant well-being.
