Abstract
The study was conducted to estimate the relation between lead exposure and the risk of various symptoms of osteoporosis in male and female battery manufacturing workers by using dual energy X-ray absorptiometry. A total of 18 female and 24 male workers were chosen with the same age range, duty hours per day, work history and weight. A total of 15 healthy controls were chosen with no previous history of bone illness and normal blood lead concentration. Blood lead concentration was measured in all workers and controls. Non-lead elevated subjects were excluded. Bone mineral density was measured by X-ray-based dual-energy X-ray absorptiometry scan machine. Spine, femur neck and radius sites were studied. Results showed that both male and female workers recorded significant elevated levels of lead concentration accompanied by osteoporosis when compared with control. Interestingly, the data revealed that fracture risk in female was significantly higher than male workers. It was concluded that lead poisoning may act as osteoporosis risk factor or co-factor in female workers by activating the conversion of osteopenia to osteoporosis.
