A study followed 750 women aged 50-94 years for a decade. Researchers wanted to see the effect of changes in bone mineral density (BMD) and appendicular lean mass (ALM) on mortality. The study found that deaths increased as BMD and ALM diminished irrespective of age.
A quote from the study, Musculoskeletal decline and mortality: prospective data from the Geelong Osteoporosis Study:
“Poor musculoskeletal health increased the risk for mortality independent of age. This appears to be driven mainly by a decline in bone mass. Low lean mass independently exacerbated mortality risk, and this appeared to operate through poor health exposures.”
