A population-based profile of adult Canadians living with participation and activity limitations.

BACKGROUND

Currently, one out of every seven Canadians is affected by limitations to their participation and activity. This study describes the self-reported main causes of these limitations in a national sample.

METHODS

The 2006 Participation and Activity Limitation Survey was a two-phase stratified survey based on filter questions posed in the 2006 Census of Population conducted by Statistics Canada. Respondents to the survey represent 5,185,980 Canadian adults with activity and participation limitations. We used these data to develop a profile of our population of interest: adult Canadians with activity and participation limitations. Associations between demographic variables and self-reported causes of activity and participation limitations were assessed using multiple logistic regression.

RESULTS

One quarter of participants did not attribute their disability to any medical cause. The most prevalent medical conditions to which disabilities were attributed were musculoskeletal (46.1%), cardio/cerebrovascular (12.3%), mental health (8.4%), neurologic (6.0%), endocrine (6.0%) and respiratory (4.5%) conditions. Significant associations were noted between sociodemographic variables and participants' attributions of medical conditions as cause of disability. Multiple logistic regression with bootstrapping showed that people who reported a medical cause for their limitation were more likely (p < 0.05) to be female, widowed, 40 years of age or older, born in Canada or white and were less likely (p < 0.05) to be in the highest income category or to be employed (i.e., to work more than 0 h/w).

INTERPRETATION

Most people living with activity and participation limitations report having a musculoskeletal disorder. However, a significant proportion of respondants did not attribute their limitations to a medical cause.
