Description
KIDNYINFYRC indicates whether the person had a chronic kidney infection in the past year. This variable is created with supplemental programming by the IPUMS NHIS staff from the pre-1997 condition records. For general information about IHIS variables (such as KIDNYINFYRC) created from the pre-1997 condition records, see the User Note on Condition Records and Condition Variables.
Defining Kidney Infection Records and Identifying Persons with a Kidney Infection
For all available years, persons who were asked a direct question about having a kidney infection and who have a chronic kidney infection condition record are given a "Yes" code for KIDNYINFYRC. Persons who were asked a direct question about having a kidney infection but do not have a chronic kidney infection record are given a code of "No." Persons who were not asked a direct question about a kidney infection, or for whom it is unknown whether they were asked such a question, are given a code of "NIU" (not in universe), regardless of whether they have a chronic kidney infection record.
For all available years (1984 to 1996), chronic kidney infection records were defined as those condition records with a code of "410" ("Kidney infections") in the variable C1CONDRC in the original NHIS public use files. This condition code value comes from NCHS's Diagnostic Recode C: Chronic Conditions and Impairments.
Weights
For all available years (1984-1996), KIDNYINFYRC should be weighted with CONDWT4.
