CHENNAI, India, February 29, 2024 — A new study out of Southern India suggests that commonly used tools for predicting osteoporosis-related fractures may underestimate risk in postmenopausal women, particularly those of South Asian ancestry. This finding could have significant implications for fracture prevention strategies worldwide.
FRAX Tool Accuracy Questioned in Indian Women

Researchers evaluated the performance of FRAX and other assessment tools in a cohort of postmenopausal women in India.
- The FRAX tool, widely used to assess fracture risk, may not be as accurate for Indian women as it is for populations of European descent.
- The study highlights the need for population-specific fracture risk assessment tools.
- Vertebral fractures, a common consequence of osteoporosis, can significantly impact quality of life.
- Researchers analyzed data from 328 postmenopausal women in Chennai, India.
How well do current osteoporosis risk assessments work for women of South Asian descent? The study, conducted in Chennai, India, reveals that the FRAX (Fracture Risk Assessment Tool) may not accurately predict vertebral fractures in this population. This is a crucial question, as osteoporosis and subsequent fractures are a growing public health concern globally.
The Study Details
Researchers retrospectively analyzed data from 328 postmenopausal women who underwent dual-energy X-ray absorptiometry (DXA) scans at a tertiary care hospital in Chennai between January 2018 and December 2022. The study aimed to evaluate the performance of FRAX, along with other parameters, in identifying women who had experienced vertebral fractures.
The analysis revealed that FRAX demonstrated a sensitivity of 66.7% and a specificity of 66.3% for detecting vertebral fractures. Furthermore, the area under the receiver operating characteristic curve (AUC) for FRAX was 0.68, indicating moderate discriminatory ability. These findings suggest that FRAX may not be optimally calibrated for the Indian population.
Why the Discrepancy?
Several factors could contribute to the observed discrepancies. Genetic predisposition, dietary habits, lifestyle factors, and differences in bone mineral density between populations are all potential influences. The study authors emphasize the importance of considering these factors when assessing fracture risk in diverse populations.
Implications for Clinical Practice
The findings underscore the need for developing and validating population-specific fracture risk assessment tools. Relying solely on tools calibrated for other populations may lead to underdiagnosis and undertreatment of osteoporosis in certain groups. Further research is warranted to refine fracture risk prediction models for women of South Asian ancestry.
“Our study highlights the importance of considering population-specific factors when assessing fracture risk,” said a researcher involved in the study. “FRAX is a valuable tool, but it may not be universally applicable.”
The study’s results were published in February 2024.
What can be done to improve fracture risk assessment for postmenopausal women of South Asian descent? Researchers suggest developing and validating tools specifically tailored to this population, taking into account genetic, dietary, and lifestyle factors.
