Does a higher nutritional risk index lower osteoporosis risk in women with Type 2 Diabetes?
Osteoporosis is a condition where bones become weak and break easily. Women with type 2 diabetes have a higher risk of osteoporosis. The Geriatric Nutritional Risk Index (GNRI) is a simple score that uses your weight and a blood protein called albumin to check your nutrition. Several studies show that a higher GNRI (meaning better nutrition) is linked to a lower chance of having osteoporosis in women with type 2 diabetes.
What the research says
A 2024 study of 324 postmenopausal women with type 2 diabetes found that those with osteoporosis had significantly lower GNRI scores than those without osteoporosis 6. The study showed that a lower GNRI was an independent risk factor for osteoporosis, meaning it was linked to higher risk even after accounting for other factors like age and weight 6.
Another study from 2022 looked at 610 older adults with type 2 diabetes in Northern China. It found that people with nutritional risk (lower GNRI) had lower bone density and were more likely to have osteoporosis 10. The GNRI helped predict who had osteoporosis, with a certain cutoff score giving good accuracy 10.
A 9-year study that followed 580 older adults with type 2 diabetes found that a lower GNRI was linked to a higher risk of breaking a bone (fragility fracture) 11. People with the lowest GNRI scores had a higher chance of hip fracture and major osteoporotic fracture over the next 10 years, as estimated by a standard tool called FRAX 11.
Taken together, these studies suggest that better nutritional status, as measured by a higher GNRI, is linked to lower osteoporosis risk and fewer fractures in women with type 2 diabetes.
What to ask your doctor
- Could my GNRI score help assess my bone health?
- What can I do to improve my nutrition and possibly lower my osteoporosis risk?
- Should I have a bone density test (DXA scan) to check for osteoporosis?
- Are there other ways to reduce my fracture risk besides nutrition?
- How often should I have my nutritional status and bone health checked?
