Activity links to lower sarcopenic obesity risk across menopause
Active women had lower post-menopausal progression risk (odds ratio 0.39) and somewhat active women had lower peri-menopausal onset (odds ratio 0.42) versus inactive peers.
Maturitas
A longitudinal cohort study tracked 1,450 Korean women aged 42 to 52 years who underwent health examinations between 2012 and 2024 and reached menopause during follow-up. Researchers evaluated sarcopenic obesity patterns relative to the final menstrual period over a median of 10.6 years using bioelectrical impedance analysis.
Annual changes averaged a 0.215 percentage point increase in body fat, a 0.038 kg/m² rise in body mass index, and a 0.011 kg/m² decline in skeletal muscle mass index. Trajectory modeling identified three distinct groups: stable low-risk (82.6%), peri-menopausal onset (6.0%), and post-menopausal progressive (11.4%). Higher physical activity levels significantly associated with reduced odds of following either adverse trajectory.
Why it matters
The menopausal transition represents a vulnerable window for adverse body composition shifts that accelerate musculoskeletal and metabolic aging. These findings identify physical activity as a key modifiable behavior linked to the preservation of muscle mass and prevention of excess fat gain during reproductive aging.
Caveats
Because this study was observational and limited to Korean women, it cannot confirm a causal relationship or generalize directly to other populations. In addition, body composition was assessed using bioelectrical impedance analysis rather than direct imaging modalities.
