Analysis of bone mineral density of the calcaneus using ultrasound in 476 healthy adult males in Bama,Guangxi

Objective To investigate the changing pattern of bone mineral density(BMD) along with the changes of age,height,weight,and BMI by testing BMD in healthy adult males in Bama,Guangxi.Methods Four hundred and seventy-six healthy adult males,aging from 20 to 111 years old,were selected randomly.They were divided into 7 groups according to a 10-year-age division.People over 80 years old were in the same group.BMD of the calcaneus was tested using ultrasound BMD detector(Korea).A SPSS1 6.0 software was used to analyze the data.Results The peak SI of BMD of the calcaneus in males presented in the group of 20-30 years old.SI of BMD declined along with the increase of age.The prevalence of osteoporosis in males increased along with the increase of age.Partial correlation analysis showed that SI of BMD in males was negatively correlated with age(r=-0.216,P0.05).And it was significantly correlated with weight(r=0.167,P0.05).But SI of BMD in males did not have correlation with height and BMI.Conclusions SI of BMD in healthy males,aging from 20 to 111 years old,in Bama,Guangxi is significantly correlated with age and weight.The SI acquired in this study provides reference value of BMD and the clinical diagnosis of osteoporosis in males in this region.
