Description

For persons under age 18 who have at least one activity limitation (LANY), and for whom epilepsy or seizures was reported as a condition causing any activity limitation (CLIMEPILEP), CLIMEPILEPNO reports the number of time units which the respondent stated when reporting the duration of the epilepsy or seizures.

Data on the duration of limiting epilepsy or seizures were collected via the question, "How long [have/has] [you/person] had [epilepsy or seizures]?" Respondents could answer this open-ended question using the time unit of their choice (i.e., days, weeks, months, year, or since birth). The original responses to the question are reported in two complementary variables, CLIMEPILEPTP (which specifies the time unit) and CLIMEPILEPNO (which, as noted above, 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 (CLIMEPILEPY) and groups of months (CLIMEPILEPMO).

Comparability

The variable is completely comparable across time.
