Description
For sample adults aged 18 and over whose doctor or other health professional did not ask them about smoking habits in the past 12 months, MDSMKNOW reports whether the reason was that the doctor, dentist, or other health professional already knew whether or not the respondent smoked or used tobacco.
MDSMKNOW is one of a series of variables dealing with doctor advice. For related variables, please use the IPUMS NHIS search function and drop-down menus.
