Codes and Frequencies
Description
For sample female adults ages 18 and older (or ages 18-59 in 1992) who have never had menstrual periods, MENSURGNEV reports whether the reason the respondent never had menstrual periods was surgery.
MENSURGNEV was first introduced in 1987. For related variables, please use the IPUMS NHIS search function or drop-down menus.
Comparability
Slight changes in the universe and survey wording may affect comparability over time. In 1987, this question was asked of sample female adults ages 18 and older. In 1992, it was asked of sample female adults ages 18-59 (see Universe Tab for more details). In 1992, respondents who no longer had, or had never had, menstrual periods were asked if this was "due to surgery, such as a hysterectomy". In 1987, they were asked if this was "due to surgery", but were not prompted about hysterectomies. As a result of these changes, researchers should use caution when making comparisons between years.
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. Data users are reminded to use the prescribed IHIS weights in their analyses.
