Title: Study of bone mineral density with quantitative CT in Ningxia Hui people.
Abstract:Objective To investigate the changes and differences of bone mineral density in Ningxia Ningxia Hui people under different age and gender.Methods A total of 181 males and 231 females from Ningxia Hui ...Objective To investigate the changes and differences of bone mineral density in Ningxia Ningxia Hui people under different age and gender.Methods A total of 181 males and 231 females from Ningxia Hui people who were confirmed normal by dual-energy X-ray absorptiometry from July 2011 to December 2011 were collected.The subjects all underwent quantitative CT and completed the questionnaire regarding the general condition.Results(1) Bone mineral density of eight volunteers was measured for three times in L 2~4 lumbar vertebral body.The quantitative CT values were corrected,and the variation coefficients were 1.82%,1.91%,1.87%.(2) The males showed peak bone mineral density from 30 to 33.8 years old,(31.1±1.2) years old in average;The females showed peak bone mineral density from 29.8 to 35.1 years old,(30.7±2.6) years old in average.With the increase of age,the bone mineral density of males was decreased gradually after the peak.The bone mineral density of females decreased gradually after the peak and decreased significantly after(43.9±2.7) years old.(3) The bone mineral density of Ningxia Hui people were closely related to the industry,weight,eating habits,the age of menopause,and showed no significant correlation with the exercise status,smoking or drinking.Conclusion The quantitative CT makes full use of the features of CT anatomical localization,and can distinguish the cancellous bone and cortical bone in three-dimensional space,selective measure the cancellous bone and exclude the effect of the measurement of the cortical bone sclerosis and adjacent tissue,with high sensitivity and specificity.The female Ningxia Hui people shows significant decrease in bone mineral density after(43.9±2.7) years old,while the males have no significant decrease,which might due to the age of the subjects.Read More
