the relationship between particulate matter and body mass index in osteoporosis

A strong relationship is observed between air pollution and a higher risk of being overweight or obese, reduced bone mineral density (bmd), and an increased likelihood of osteoporosis.  this study aimed to examine the relationship between suspended particles and body mass index (bmi) in patients with osteoporosis and osteopenia. data on particulate matter (pm) collected by the abadan environmental protection department from february 1, 2022, to august 22, 2023, were utilized in abadan city, iran. demographic information, along with the bmd and t-scores of the patient’s left femur and lumbar spine (l1-l4), as well as the bmi of patients with osteoporosis, osteopenia, and those with normal bone density, were obtained from the files of individuals referred to the nuclear medicine center. in this study, out of 431 individuals referred to the density measurement center, 383(88.9%) were women and 48(11.1%) were men. the participants mean bmi was 28.78±5.45, indicating that it was elevated across all three groups (normal, osteopenia, and osteoporosis). the mean concentrations of pm2.5 and pm10 on the days of admission of the study participants were 95.51±126.05 and 188.62±181.11, respectively. the pearson correlation analysis between pm10, pm2.5, and bmi revealed no significant relationships. in this study, the average bmi among the groups (osteopenia, osteoporosis, and normal bmd) was above the normal range, and no significant correlation was observed between pm and bmi.
