Description
For sample persons age 18 and over, HYPCHECKMO reports the number of months since blood pressure was last checked by a doctor or other health professional.
Comparability
Apart from changes in the universe, there are no comparability issues. Changes in survey design (e.g., quarters in which the supplement was collected) may affect raw frequencies, but do not affect comparability of the variable. As always, data users should use the prescribed IPUMS NHIS weights.
