I need some assistance in locating certain variables on the NHIS core or person-level 1994 and 1995 files.
In particular, I am looking for smoking status (current, former, never) and chronic condition indicators including hypertension, heart disease, diabetes, lung disease, stroke, cancer.
I have used the 1997 to 2004 NHIS data with these variables, but I am having trouble locating the variables on the 1994 and 1995 files.
These are the codebooks that I have been using to locate the variables. Can you tell me if these variables are available on the 1994 and 1995 files?
