Polymorphisms in Estrogen Synthesis Genes and Symptom Clusters During the Menopausal Transition and Early Postmenopause: Observations From the Seattle Midlife Women's Health Study.

During the menopausal transition and early postmenopause, participants in the Seattle Midlife Women's Health Study (SMWHS) experienced one of the three symptom severity clusters identified through latent class analysis: severe hot flashes with moderate sleep, mood, cognitive, and pain symptoms (high-severity hot flash); low-severity hot flashes with moderate levels of all other symptom groups (moderate severity); and low levels of all symptom groups (low severity). In an effort to determine whether gene polymorphisms were associated with these symptom severity classes, we tested associations between gene polymorphisms in the estrogen synthesis pathways (cytochrome P450 19 [CYP 19] and 17 beta hydroxysteroid dehydrogenase [ 17HSDB1]) and the three symptom severity clusters. SMWHS participants ( N = 137) recorded symptoms monthly in diaries and provided buccal smears for genotyping.

Symptom clusters during the late reproductive stage through the early postmenopause: observations from the Seattle Midlife Women's Health Study.

Objective: The aim of this study was to identify symptom clusters that characterize women's experiences through the late reproductive stage, the menopausal transition, and early postmenopause and to explore the influence of the menopausal transition stages and early postmenopause, compared with that of the late reproductive stage, on the clusters of symptoms women experience.

Methods: Participants from the Seattle Midlife Women's Health Study whose symptom calendars were staged for the menopausal transition provided data for a total of 6,857 occasions. Multilevel latent class analysis was used to identify classes using scores for hot flashes and symptom factors (sleep, cognitive, mood, pain, tension).
