Description
For sample female adults who have not had a menstrual period in the last three months and who are not currently pregnant (for 1999) or whose menstrual periods have stopped permanently (for 1987), MENSLAGE reports the age at which the respondent had her last menstrual period.
MENSLAGE was first introduced in 1987 as part of a supplement on cancer epidemiology. For related variables, please use the IPUMS NHIS search function or drop-down menus.
Comparability
Changes in the universe may affect comparability between years. For 1987, this question was asked of sample female adults ages 18 and older whose menstrual periods have stopped permanently. For 1999, this question was asked of sample female adults who have not had a menstrual period in the past three months. (See the Universe Tab for more details.) Because of these changes, researchers should use caution when making comparisons across years.
