[Epidemiology of respiratory diseases and osteoporosis.]

Abstract

A large scale of epidemiological studies demonstrated that osteoporosis risk was about 1.5 times higher and fracture risk was 1.2-1.8 times higher among COPD patients. In COPD, risk factors for fracture have been reported to be severity of the COPD and use of bronchodilator in addition to ordinal risk factors for the fracture such as age, previous fracture, smoking, usage of glucocorticoid and others. There were inconsistent results of the relationship between sleep apnea and low bone mass. The relationship was found between sleep apnea and fall and non-spin fracture risk.
