Anxiety disorders among older Canadians: Focus on Indigenous and racialized population groups.

Abstract

Background: Anxiety disorders are among the most common mental health problems. However, few studies have examined the prevalence of, and factors associated with, anxiety disorders among older Canadians (65 years or older), with a particular focus on Indigenous and racialized population groups.

Data and methods: Data from eight cycles of the annual Canadian Community Health Survey (CCHS) - 2015 to 2022 - were used to examine anxiety disorders among older Canadians. Multivariable logistic regression, stratified by sex, was carried out on a pooled sample of 151,755 respondents aged 65 years or older.

Results: From 2015 to 2022, on average, 6.0% of older Canadians reported a diagnosis of an anxiety disorder, with females (7.5%) more likely than males (4.2%) to have done so. Indigenous males had higher odds of having an anxiety disorder than non-Indigenous, non-racialized males, while Chinese and other racialized females had lower odds of having an anxiety disorder than non-Indigenous, non-racialized females.

Interpretation: Findings of this study highlight the importance of considering Indigenous and racialized population groups disaggregated by sex when examining anxiety disorders among older Canadians to inform screening and intervention programs.
