Objective To investigate the distribution of prevalence of primary osteoporosis (POP) in the middle aged and the elderly in parts of China. Methods Bone mineral density (BMD) was measured and questionnaire was surveyed from 5 602 people aged above 40 years old in five administrative areas in China, by the stratified multi steps cluster sampling method. Results The total prevalence of POP in these population was 12.4％ according to the most significant parts of the accumulation lose rate. Among them, the prevalence was 8.5％ in male and 15.7％ in female(P

Objective To investigate the normal references of standardized bone mineral density (sBMD) and provide important basis for diagnosis and treatment of osteoporosis. Methods Using Dual Energy X－ ray Absorptiometry (DEXA), the bone mineral density was measured in 2 331 people aged above 20 years in parts of China by the method of random sampling， the study was standardized by equations. Results The normal references and peak values of sBMD in lumbar spine and proximal femur were determined based on sex and age. Conclusion This study provides the treatment references and the diagnosis references of sBMD for osteoporosis.

ObjectiveTo assess the superiority of comprehensive therapy in the elder with osteoporotic hip fracture.Methods163 elderly patients with osteoporotic hip fracture were retrospectively analyzed,in which 50 patients accepted routine therapy only,and other 113 patients accepted routine therapy combined with anti-osteoporosis comprehensive therapy.The effect and the incidence of complications in two groups were compared. Results105 patients had been followed-up for 5—36 months. There were the high effective rate and the low complication rate in the group of comprehensive therapy(P<0.05),compared with the routine group. Conclusions Comprehensive therapy should be adopted in the elder with osteoporotic hip fracture.

Objective To investigate osteoporosis prevalence in the elderly with type 2 diabetics. Method Osteoporosis prevalence in 338 elderly patients with type 2 diabetics (60-69 and 70-79 years old, respectively) was compared with 199 non-elderly (50-59 years old) patients and 531 elderly subjects from local reference data. Bone mineral density was measured at lumbar spine and proximal femur in DPX-L. Results (1) In female patients, osteoporosis prevalence at both sites in the elderly group was higher than that in non-elderly group (all P

OBJECTIVETo understand the distribution of prevalence rate of osteoporosis in the middle - aged and elderly in parts of China.

METHODSBone mineral density (BMD) was measured and questionnaires were taken for 5593 people aged above 40 years in five administrative areas in China selected by the stratified - multi - steps - cluster sampling method.

RESULTSThe total prevalence rate of osteoporosis was 16.1%. The prevalence rate among males was 11.5% and among females was 19.9% (P < 0.01). There were also osteoporosis prevalence differences among cities, age groups, gender groups and areas.

CONCLUSIONThe prevention and treatment of osteoporosis are very important for females but also should not be ignored in males.
