Sleep problems persist in middle-aged women and influence changes in health but are moderated by menopause and its treatment

OBJECTIVE: This study aimed to compare the self-reported sleep problems of middle-aged women who had not menstruated for more than a year (postmenopause), those who have menstruated within the last year (premenopausal/perimenopausal) and those who could not have menstruated for medical reasons (e.g. hysterectomy). METHOD: = 20,000) analyses, drawing on responses from baseline and follow-up self-reported questionnaires. RESULTS: < 0.05). CONCLUSION: While not supported by objective measures of sleep, health or hormones, these results add substantially to the literature on women's sleep, health and menopause, highlighting the potential benefits of early, tailored interventions and timely hormone replacement therapy use for improving sleep and well-being in midlife.
