A systematic review of the longitudinal relationships between subjective sleep disturbance and menopausal stage.

Sleep disturbance is a common complaint for women going through the menopausal transition. A previous systematic review and meta-analysis of cross-sectional studies showed a small but significant relationship between self-reported sleep disturbance and menopausal stage and highlighted a possible influence of culture. However, the longitudinal relationship between self-reported sleep disturbance and menopausal transition has not been explored.
