The Claim
In community-dwelling older adults at risk of falls, the full MNA-Total score (0–30 scale) is not significantly associated with skeletal muscle mass index, knee extension strength, gait speed, or timed-up-and-go performance.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In older adults at risk of falls, the full MNA-Total score does not correlate with measures of muscle mass, leg strength, walking speed, or time to stand and walk.
See the scientific wording
In community-dwelling older adults at risk of falls, the full MNA-Total score (0–30 scale) is not significantly associated with skeletal muscle mass index, knee extension strength, gait speed, or timed-up-and-go performance, suggesting that the screening component may be more predictive than the comprehensive assessment for these outcomes.
The body's muscle size and strength depend on mechanical use and protein availability, but in older adults at risk of falls, short-term nutritional cues do not directly control these muscle traits. Instead, movement patterns and physical activity levels determine muscle performance, while overall nutrition affects other systems that do not strongly link to these specific outcomes.
What the research says
1 studyFor older adults at risk of falling, a short nutrition quiz predicts muscle strength and walking ability better than a longer, more detailed quiz — and the full combined score didn’t predict anything at all.
