New findings from non-linear longitudinal modelling of menopausal hormone changes.
Changes in  FSH and estradiol ( E2 ) across the menopausal transition are clearly not linear . The present study utilizes data from 204 women who completed the 13-year prospect i ve Melbourne Women 's Midlife Health Project .  E2 , FSH , symptoms , self-rated health , mood , sexual function and coronary heart disease ( CHD ) risk were measured longitudinally . We presumed an s-shaped curve for each hormone and estimated five parameters for each hormone curve for each woman : baseline , final value , range , slope at inflexion point and age at inflexion point . These parameters were found to adequately estimate the curve for each hormone . The median age of transition observed for E2 occurs > 1 year later than the median age of transition observed for FSH . FSH parameters did not affect any of the health outcomes analysed . Hot flushes , night sweats , sleeping problems , vaginal dryness and to a lesser extent self-rated health were highly significantly associated with E2 range and slope . Sexual response and CHD risk were highly significantly associated with final E2 level ( post-menopausally ) . These findings have clinical relevance in identifying which symptoms will be triggered by steep transitions of E2 such as sudden withdrawal and which health parameters may require a maintenance level of E2
