Description

For persons who have at least one activity limitation (LANY), and for whom a vision problem was reported as a condition causing any activity limitation (CLIMVISIONY), CLIMVISIONY reports the duration, in years, of the vision problem.

Data on the duration of limiting vision problem were collected via the question, "How long [have/has] [you/person] had [a vision problem]?" Respondents could answer this open-ended question using the time unit of their choice (i.e., days, weeks, months, or years). The original responses to the question are reported in two complementary variables, CLIMVISIONTP (which specifies the time unit) and CLIMVISIONNO (which reports the number of such units). For the NHIS public use files, the National Center for Health Statistics (NCHS) recoded the results from these two variables to create two other variables using standard time units: years (CLIMVISIONY) and groups of months (CLIMVISIONMO).

Comparability

Apart from a change in the coding of "unknown" cases, this variable is comparable across years.

[show more]

In 2002 forward, the unknowns were categorized as:

Unknown number of years (IPUMS NHIS code 96)

Unknown-refused (IHIS code 97)

Unknown-not ascertained (IHIS code 98)

Unknown-don't know (IHIS code 99)

However, in 1997-2001, the category of "Unknown number of years" did not occur.

Analysts can achieve comparability across all years by combining two-digit codes for 96 forward into a single "unknown" category.
