Menopause transition stage and endogenous estradiol and follicle-stimulating hormone levels are not related to cognitive performance: cross-sectional results from the study of women's health across the nation (SWAN).
2007
Background: By one estimate, 60% of women experiencing the menopause transition perceive that they have memory problems, but most studies that have used cognitive function tests have not substantiated a relation between menopause stage and cognitive performance. We sought to describe the cross-sectional relation between menopause status, estradiol (E2), follicle-stimulating hormone (FSH), and measured cognitive function. Methods: Cross sectional analysis of a community-based cohort of midlife women was used. Cognitive tests were the East Boston Memory Test, Symbol Digit Modalities, and Digits Span Backward. Menopause categories (premenopausal, early perimenopausal, late perimenopausal, and postmenopausal) were defined based on menstrual patterns. One set of general linear models assessed the relations between each cognitive test and menopause transition category, initially adjusted for age, race/ethnicity, education, symptoms, self-rated general health, and body mass index (BMI); next, these were addition...
