Description
For sample adults age 18 and over who have had their cholesterol level checked (or don't know whether they have had their cholesterol level checked), CHOLDIETADV reports if a doctor or other health professional ever advised the person to go on a diet or change eating habits to lower his or her cholesterol. Persons who were advised to change their eating habits were asked whether they were following this advice (CHOLDIETFOL).
This variable was part of annual supplements (Adult Prevention in 1998; Year 2000 in 1993; Health Promotion and Disease Prevention in 1991). For related variables, please use the IPUMS NHIS search function and drop-down menus.
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 IHIS weights.
