Description

For Sample Adults age 18+ who, without using special equipment, had any difficulty with one or more functional activities (FLANY), and for whom a skin problem was reported as a condition causing a functional activity limitation (FLSKIN), FLSKINTP reports the time unit in which the duration of the skin problem was measured by the respondent.

Data on the duration of the limiting nervous condition were collected via the question, "How long have you had [a skin problem]?" Respondents could answer this open-ended question using the time unit of their choice (i.e., days, weeks, months, years, or since birth). The original responses to the question are reported in two complementary variables, FLSKINTP (which, as noted above, specifies the time unit) and FLSKINNO (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 (FLSKINY) and groups of months (FLSKINMO).

The 1997 forward NHIS Survey Descriptions caution that because the ad hoc classified condition categories (such as a "skin problem" (FLSKIN)) were not included on flashcards given to respondents during the course of the interview, it is possible that weighted frequencies for these conditions may be underestimated. Thus, the NCHS recommends that "these variables should be analyzed with care."
