Collection and usage attributes
|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.
Count age in completed years.
If onset of disability occurs before the second birthday, record age in months (see the data element Person—age at onset of disability, total months N[N]).
