Description

For sample persons ages 18 and older who have been tested for HIV, AIDTYRNO reports the number of HIV tests the person has had in the past 12 months. Please see the Comparability tab for a discussion of changes in universe and categories across samples.

Comparability

Changes in the universe over time affect the comparability of this variable. In 1988-1989, AIDTYRNO is restricted only to sample persons 18 and older who have been tested more than once. From 1990 until 1995 the universe expands to include sample persons 18 and older who have ever been tested for HIV. In 2002 this only includes sample adults who have been tested in the past 12 months.

In 1988-1990, responses were top coded at 12 tests; this top code was removed in subsequent years.

Changes in survey design (e.g. quarters or subsamples) affect raw frequencies but do not affect comparability between samples. As always, data users should apply prescribed IPUMS NHIS weights.
