Transition to menopause has long been considered a period of increased risk for depressive symptoms. However, the extent to which this period is one of increased risk for major depressive disorder is less clear. Some
1,2 but not all,
3,4 studies suggest an association between the menopausal transition and significant psychosocial impairment with concomitant vulnerability to depressive symptoms. These inconsistent findings may be due at least in part to variability in study designs and other methodological limitations. For example, there has been little uniformity with respect to selection of study participants, with some studies targeting specialized menopause clinics, while others have included subjects from community-based samples. Another source of inconsistency across some studies has been the definition of menopausal status. Menopausal status has frequently been assigned based on 1 single criterion (eg, age) or by a combination of various criteria including age, presence of menopause-related symptoms, hormone levels, or history of menstrual cycle irregularity. Last, some studies have lacked a standardized assessment of psychiatric symptoms or disorders and/or rigorous criteria to delineate severity of depressive episodes.
