Positive associations between menstrual lifespan, geriatric depression and healthy longevity in Chinese oldest-old and centenarian women.

OBJECTIVE: Menstrual lifespan (ML) is an important biological characteristic for women. Rare evidence has established the associations between menopause age (MI), geriatric depression and healthy longevity. This study aimed to address these associations in Chinese oldest-old and centenarian women, and explore their related factors in order to provide strategy support for healthy aging. METHODS: The China Hainan Centenarian Cohort Study provides a population-based sample in Hainan, China. A total of 723 women including 318 centenarian women and 405 oldest-old women aged 80-99 years were included in this study. Data on demographic information were collected using a structured questionnaire. Physical examination and blood samples were obtained following standard procedure. Geriatric Depression Scale (GDS-15) was used to evaluate depressive symptoms for all participants. RESULTS: The proportions of participants with depression and longevity were 19.78 % (143 older adults) and 43.98 % (318 older adults), respectively. After adjusting for a wide range of other covariates in multiple logistic regression analyses, ML was positively and significantly associated with depression and longevity [Exp(ß) 1.076 and 1.121; P < 0.05 for all]. In multiple linear regression analyses, there were significantly positive associations of ML with GDS-15 (ß = 0.061) and age (ß = 0.238, p < 0.05 for all) after adjusting for all covariates. CONCLUSIONS: This study provides epidemiological evidence that menstrual lifespan has positive associations with geriatric depression and healthy longevity in Chinese oldest-old and centenarian women. Future researches should focus on the effects of intervening MI on psychological health and successful longevity.
