ASTH1STAGE is a 2-digit numeric variable. Ages begin at 0 and are top-coded at 85 for all years. Missing value codes are as follows:
97: Unknown - Refused
98: Unknown - Not ascertained
99: Unknown - Don't know
Description
For sample adults age 18 and over who were currently employed or employed at some time in the past 12 months and still have asthma, ASTH1STAGE reports how old the respondent was when he or she was diagnosed with asthma. Researchers interested in a less detailed measure may want to use ASTH1STAGE16, which reports whether or not the respondent was younger than 16 when first diagnosed with asthma.
