Little is known about the nature of Canadian children with participation or activity limitations. Our objective was to profile a nationally representative sample of Canadian children with report of participation or activity limitation including identifying the major medical reasons attributed to these limitations and describe their sociodemographic and functional characteristics. We used data from the Canadian 2006 Participation and Activity Limitation Survey, a post-census Statistics Canada national survey of adults and children whose everyday activities were limited because of a condition or health problem. Data were collected by telephone interview of children's (<15 years) parents. A sample of those who answered 'yes' to the 2006 Canada Census disability filter questions was chosen for follow-up. Functional ability was assessed using the Health Utility Index. Mental health (26.1%) was the most common reason reported for participation and activity limitations followed by respiratory (9.8%), neurological (5.5%), and congenital (4.6%) conditions. Having a comorbid condition was associated with each major reason for limitation. Mental health, neurological, and congenital conditions showed the highest risk of functional limitation. In conclusion, mental health conditions and those with multiple conditions should be a primary focus for interventions aimed at reducing the impact of health conditions.
