Early and ate perimenopause and early postmenopause were defined as outlined in the Stages of Reproductive Aging Workshop +10 criteria33. Early perimenopause was defined as persistent menstrual cycle length change of at least 7 days longer than typical for that individual; late perimenopause was defined as an interval of amenorrhea of at least 60 days; early postmenopause was defined as within two years of their final menstrual period30. Within early postmenopause hormone variability is still present as are vasomotor menopause symptoms33.
