Timing of menopause and patterns of menstrual bleeding.

Age at menopause is associated with a variety of health outcomes. Menstrual histories, both as markers of physiologic function and through their potential association with age at menopause, have also been investigated for their links to health outcomes. This study used data from a cohort of women from the United States who provided prospectively recorded data on their menstrual cycles for many years.

Damage to the cervical spine was due to fractures of the C-6 body and superior articular facet undetected by routine radiologic studies.
