Clinical analysis of bone mineral density of the calcaneal region in 11 559 cases in Wuhan district

Objective To investigate the prevalence of osteoporosis in Wuhan,in order to provide scientific basis for the prevention and treatment of osteoporosis.Methods Bone mineral density(BMD) assessment of right calcaneal region(11 559 citizens who had medical examination in Jianghan District of the WuHan City from 2004 to 2008,including 6434 men and 5125 women,aged from 20 to 99) were measured with dual energy X-ray absorptiometer(DXA). Prevalence of osteopenia and osteoporosis are analyzed according to BMD.Subjects were divided into groups according to different age and sex.Results The percentage of the normal bone mass decreased as the age increased,while the percentage of the osteopenia and osteoporosis was reverse.Male and female had significant differences of the BMD,no matter in which age group,in case of the same bone mass status(P0.05).Conclusion The prevalence of osteopenia or os- teoporosis increaseed with age.The 20-year-group had the highest percentage of normal bone mass and the lowest percentage of osteopenia and osteoporosis.Females are more liable to suffer from osteoporosis.Males had higher BMD than females.
