Codes and Frequencies
For sample females ages 30 and older who have had a breast exam (BXEV), BREXWHY reports the reason for the most recent breast exam: a specific breast problem, follow-up to a previous exam, part of a routine physical (or pregnancy) exam, or other. In 1992, BREXWHY was asked of half of female sample persons ages 30 and older in quarters 1 and 2 and in 2 weeks of quarter 3 (excluded from CAEP supplement) who have ever had a breast physical exam and whose most recent exam was in the past 3 years.
BREXWHY was first introduced as part of a supplement on cancer control. For related variables, please use the IPUMS NHIS search function and drop-down menus.
Comparability may be affected by changes in the universe and response categories and the 2019 questionnaire redesign. 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.
