Description

KIDNEYWKYR identifies sample adults whom a doctor or other health professional had diagnosed as having weak or failing kidneys during the past 12 months. Respondents were instructed to exclude "kidney stones, bladder infections, or incontinence." In 2020, KIDNEYWKYR was asked only of sample adults interviewed in quarter 3 or 4.

In 1999, a separate question identified sample adults whom a doctor or other health professional had diagnosed as having kidney stones in the past 12 months (KIDNYSTONYR). In 2002 and 2007, sample adults who had ever been told by a doctor or other health professional that they had urinary problems (such as incontinence, frequent or slow urination, or infections) were identified (URINPROBEV). Those identified as ever having such urinary problems were asked whether they had such problems during the past 12 months (URINPROBYR).

Comparability

While the basic meaning of this variable is completely comparable over time, major questionnaire changes introduced in 2019 may affect comparability with earlier years. The NHIS questionnaire was substantially redesigned in 2019 to introduce a different data collection structure and new content. For more information on changes in terminology, universes, and data collection methods beginning in 2019, please see the user note.
