Menarche age, menopause age and other reproductive factors in association with post-menopausal onset depression: Results from Health Examinees Study (HEXA)
Abstract
Background: Although there are plausible mechanisms of female hormones in depression, epidemiological evidence has shown conflicting results.
Objective: This study aimed to evaluate the associations between female hormonal events and post-menopausal depression and further investigate the relative association between the age of menarche, the age of menopause and depression.
Methods: Among 111,589 women who took part in the Health Examinees (HEXA) Study, a total of 60,114 postmenopausal participants were included in the final analysis. Each participant provided information on depression and questions related to reproductive history. The outcome variable was self-reported by the history of depression diagnosed by physicians and the Center for Epidemiologic Studies Depression Scale (CES-D) score. With the multivariate logistic regression, odds ratios were calculated. Possible interactions between depression prevalence and the ages of menarche and menopause were assessed.
Results: A total of 2.2% (1342/60,114) women were diagnosed with depression after menopause, and 5.9% (500/8472) showed depressive symptoms. As the age of menopause and duration of reproductive years increased, the odds ratio of depression decreased (P-trend <0.001). As the age of menarche increased, the likelihood of physician-diagnosed depression also increased (P-trend 0.048). As the number of both spontaneous and induced abortions increased, the odds ratio of depression increased (P-trend <0.001).
Limitation: it is possible that women show inaccuracies in recalling their hormonal events and reporting other past mental disorders as depression.
Conclusion: Both the ages of the initiation and the termination of menstruation were associated with the increased odds ratio of post-menopausal depression. However, the age of menopause seems to be more important.
