The Study
Malnutrition is associated with poor muscle mass and physical performance in community-dwelling older adults: COINS study baseline data
This study looked at a group of older people and found that those who scored lower on a nutrition test also tended to have weaker muscles and move slower. But it didn't watch them over time, so we don't know if eating less made their muscles weak, or if their weak muscles made them eat less.
Analysis score
Maximum 44 for a cross-sectional study.
Where the score came from
Researchers checked if a quick nutrition quiz (MNA-Screening) or a longer one (MNA-Assessment) could predict how strong or mobile older adults are.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — a 15-minute nutrition screen may catch muscle loss earlier than a longer assessment, helping identify who needs help before they fall.
- 2Quick quiz: linked to stronger legs and more muscle.
- 3Long quiz: linked to faster walking and quicker standing up.
- 4Combined score: not linked to anything.

Older adults at risk of falling who score higher on a basic nutritional screening test tend to have stronger knee muscles and more skeletal muscle mass per unit of body size.
Among older adults at risk of falls, those with higher nutritional scores on the MNA assessment walk faster and complete mobility tests more quickly.
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.
In older adults living at home who are at risk of falling, 15% are flagged as at-risk or malnourished using a quick screening tool, but only 6.7% are flagged using a more detailed nutritional assessment.
In older adults at risk of falls, a nutritional screening score called MNA-Total does not predict muscle mass, leg strength, walking speed, or mobility better than those individual measures alone.
Among older adults at risk of falls, the MNA-Screening tool identifies 15% as at risk of malnutrition, while the full MNA-Assessment identifies only 6.7%, showing that screening captures more individuals with potential muscle decline than comprehensive assessment.
