The Claim

The coexistence of low lean mass (defined by Baumgartner criteria) and osteoporosis (T-score ≤ -2.5) is associated with a 3.39-fold increased risk of low-trauma fractures compared to individuals with normal lean mass and normal bone density.

In plain English

People with both low muscle mass and osteoporosis have 3.39 times higher risk of breaking a bone from a minor fall than people with normal muscle mass and bone density.

See the scientific wording

The coexistence of low lean mass (Baumgartner definition) and osteoporosis (T-score ≤–2.5) increases the risk of low-trauma fractures by 3.39-fold compared to individuals with normal lean mass and bone density, indicating a synergistic effect between muscle and bone loss.

Why this might work

Less muscle mass weakens the body's ability to control movement and absorb impact, making falls more likely from standing height. At the same time, weaker muscles pull less on bones during daily activity, causing bones to become thinner and more fragile. When a fall happens, the combination of poor balance and weak bones leads to fractures at common sites like the wrist, ankle, or shoulder.

    Older adults who have both weak muscles and weak bones are more than three times as likely to break a bone from a minor fall than those with normal muscle and bone strength — and this study proved it by tracking thousands of seniors over three years.
