Codes and Frequencies
For sample persons age 40 and over, PROCEXAMEV reports if he or she has ever had a proctoscopic exam.
For related variables, please use the IPUMS NHIS search function and drop-down menus.
Apart from changes in the universe, this variable is mostly comparable over time. 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 IHIS weights.
