Comments
Guide for use:
This data element relates to the age of onset of an impairment, activity limitation or participation restriction (including present at birth), which may be different from the age that a person needs assistance because of that impairment, limitation, or restriction.
The onset of disability may be later than the first appearance of a health condition that eventually results in disability.
Context:
The onset of disability may indicate a current or future need for assistance.
