The Correlation between Bone Mineral Density and Particulate Matter in Patients with Osteoporosis
Abstract
Background: This study examined the correlation between bone mineral density (BMD) and particulate matter (PM) in patients with osteoporosis.
Methods: People with osteopenia, osteoporosis, and normal BMD were included in the study. BMD, bone mineral content (BMC), T-scores, and Z-scores of the lumbar vertebrae (L1-L4) and femur were obtained by dual-energy X-ray absorptiometry (DEXA). Daily PM2.5 and PM10 concentrations during the study period (January 21, 2022, to May 21, 2023) were obtained from local monitoring stations, with missing data estimated using satellite-derived aerosol optical depth (AOD).
Results: In patients with osteoporosis, inverse correlations were observed between PM2.5 and PM10 and BMD, BMC, T-scores, and Z- scores in different parts of the femur (except femoral neck T-score) and lumbar spine. Still, none of the correlations was statistically significant.
Conclusion: There was no significant correlation between the mean concentration of PM2.5 and PM10 and the parameters of BMD, BMC, T-score, and Z-score in the bones of the femur and lumbar spine of patients with osteoporosis.
