For sample persons age 18 and older, AIDDAMBRA indicates if the person believes the statement "AIDS can damage the brain" to be true or false.

This variable is part of the NHIS supplement on AIDS knowledge and attitudes. For related variables, please use the IPUMS NHIS search function and drop-down menus.


The response categories changed over time. From 1988-1990, sample persons were asked to what extent they believed the statement to be true, ranging from "definitely true" to "definitely false". Starting in 1991, sample persons were asked only if they believed the statement to be true or false.

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.


  • 1988: Sample persons age 18+ in quarters 2 through 4.
  • 1989-1992: Sample persons age 18+.


  • 1988-1992
