View abstract on PubMed
Summary
This summary is machine-generated.Both early and late menopause accelerate frailty progression in Chinese women. Understanding menopause timing is crucial for promoting healthy aging and implementing timely interventions for women experiencing atypical menopause.

- Epidemiology
Background
- Menopause is a key life stage influencing long-term health.
- The timing of menopause impacts later-life health risks.
- The relationship between menopause timing and frailty progression in Chinese women is not well understood.
Purpose Of The Study
- To investigate the association between age at menopause and the longitudinal progression of frailty.
- To analyze frailty progression across different menopause timing categories in Chinese women.
Main Methods
- Prospective cohort study (China Health and Retirement Longitudinal Study, 2011-2018).
- Included 11,984 women aged 45+ experiencing natural menopause.
- Frailty index calculated from 30 health deficits; menopause age categorized (<40, 40-44, 45-49, 50-55, >55 years).
- Mixed-effects linear regression models used for analysis, adjusting for confounders.
Main Results
- Late menopause (>55 years) showed the fastest frailty progression (β=0.43, P=0.027).
- Menopause at ages 40-44 also significantly accelerated frailty progression (β=0.35, P=0.016).
- Premature ovarian insufficiency (<40 years) was linked to lower baseline frailty and slower progression.
Conclusions
- Both early (<40 or 40-44 years) and late (>55 years) menopause are associated with increased frailty progression.
- Early identification and intervention for women with atypical menopause timing are essential for healthy aging.
- Findings emphasize the importance of monitoring menopause timing for geriatric health management.
