Description

For sample adults age 18 and over, CHOLCHEKYRG reports the last time (in grouped years) the person had a blood cholesterol level check by a doctor or other health professional.

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

Changes in the response categories across years reduce comparability. See the Survey Text tab to compare response categories between samples.
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. Aside from this, there are no comparability issues.
