Investigation of bone mass density and prevalence rate of osteoporosis in healthy Hui people in Ningxia Province

Objective To investigate the BMD and the incidence of osteoporosis(OP) in healthy hui people in NingXia Province of China,To obtain the reference ranges of the bone density(BMD) in healthy Hui people in Ningxia Province,and provide scientific basis for diagnosis and treatment of osteoporosis.Methods 384 healthy hui people were divided into groups according to age and sex.The range of age was 30 to 80 and divided into groups of 10 yeas each.Their Bone mass density(BMD) at the right distal of radius were measured by dual energy X-ray absorptiometry(DEXA),then statistically analyzed.Results ① The peak value of BMD appeared during 30 to 39 years of age in every groups and BMD decreased with age During 50 to 59 years of age,the BMD of females dropped obviously;The prevalence rates of OP(WHO) after 50 years of age were 28.8% in male and 41.9% in female;② LiBai had no effect on BMD in male and female;③ There are positive correlation between the BMD and height in male and female,as well as the BMD and weight in male.Conclusion ① BMD decreases with age,and the incidence of osteoporosis increases with age.The incidence of OP in females is higher than that in males;② LiBai have no effect on BMD in male and female;③ Height and weight be both influence factors to BMD.
