The analytic sample consisted of 2,956 women for whom we had 23,532 person years ofobservations over the 10 years of annual visits. We compared the baseline characteristics ofwomen with and without high anxiety at baseline to identify factors that were significantlydifferent between these groups. Longitudinal random effects logistic regression models wereused to examine the odds of having high anxiety for each menopausal stage (premenopause,early perimenopause, late perimenopause, natural postmenopause and postmenopause withHT use) from study entry through visit 10. Women were censored at the visit when theirmenopausal stage was undetermined (premenopausal or perimenopausal and concurrent useof HT, which can cause bleeding), but their data were included in subsequent analyses oncethey ceased HT use and stage could be determined. Women who reported having ahysterectomy and/or oophorectomy were censored from that visit forward.
