Hypothesis
Is the Geriatric Nutritional Risk Index (GNRI) associated with bone stiffness and osteoporotic fracture risk in elderly men and women?
Conclusion
The GNRI is positively associated with bone stiffness and lower osteoporotic fracture risk in elderly individuals with underweight or normal weight.
Supporting Evidence
- In underweight/normal weight individuals, higher GNRI values positively affected the stiffness index.
- Better GNRI values were associated with higher chances of a low osteoporotic fracture risk.
- Associations were absent in overweight or obese individuals.
Takeaway
This study found that older people who are underweight or have a normal weight and have better nutrition scores are less likely to have weak bones.
Methodology
Data from 1417 elderly participants were analyzed using linear and logistic regression models to assess the relationship between GNRI and bone stiffness.
Potential Biases
Self-selection bias may have occurred as participants needed to have physical and cognitive resources to participate.
Limitations
The study had a small number of underweight/normal weight individuals, limiting the statistical power of subgroup analyses.
Participant Demographics
The study included 755 men and 662 women aged 65 to 90 years.
