Alcohol use among immigrants in Ontario, Canada.

INTRODUCTION AND AIMS

This study examined prevalence of alcohol consumption among immigrants and the Canadian-born populations of Ontario by ethnic origin, and the association between ethnicity, country of birth, age at arrival, length of residence in Canada and drinking measures.

DESIGN AND METHODS

Data were derived from the Centre for Addiction and Mental Health (CAMH) Monitor, a cross-sectional survey of Ontario adults, conducted between January 2005 and December 2010 (n = 13,557).

RESULTS

The prevalence of alcohol consumption and risk drinking was generally lower among foreign-born than Canadian-born respondents, but significant variations across ethnic groups were found. In general, foreign-born respondents of European descent reported higher rates of alcohol use and risk drinking than foreign-born respondents from other ethnic groups. We also observed that ethnicity effects varied by whether or not respondents were born in Canada, and by the age at which they arrived in Canada.

DISCUSSION AND CONCLUSIONS

While previous studies generally found an increase in immigrants' alcohol consumption with years in Canada, our data suggest that longer duration of residence may have either positive or negative effects on immigrants' alcohol use, depending on the country of origin/traditional drinking pattern. More research is needed to explore determinants of alcohol use and risk drinking among immigrants and to identify those groups at highest risk.
