Evaluation of the relationship between abdominal fat distribution and osteoporotic vertebral compression fracture with MRI.

OBJECTIVE

This study was carried out to investigate the effects of abdominal subcutaneous adiposity and visceral adiposity on osteoporotic compression fractures.

MATERIAL AND METHODS

The study group consisted of a total of 152 individuals aged 50-80 years; 76 were included in the vertebral fracture group and 76 in the healthy control group, whose bone mineral density was calculated. In order to determine the distribution of abdominal fat in both groups, four different measurements, i.e., sagittal abdominal diameter (SAD), abdominal diameter (AD), ventral subcutaneous thickness (VST), and dorsal subcutaneous thickness (DST), were made using lumbar magnetic resonance imaging (MRI). The visceral fat ratio (VFR) was also calculated based on these measurements.

RESULTS

There was a significant difference between the patient and control groups in VST and DST values, both when gender distribution was and was not taken into account (p < 0.006 for all cases). There was no significant difference between the patient and control groups in SAD and AS values, both when only female patients were considered, and gender distribution was not taken into account (p > 0.25 for all cases). On the other hand, in the analysis, when only male patients were considered, the SAD and AD values of the patient group were found to be significantly lower than those of the control group (p = 0.046 and p = 0.048, respectively).

CONCLUSION

In conclusion, the study findings indicated that high SAD values in the male gender and high VST and DST values in both genders were associated with low lumbar vertebral fracture risk.
