摘要
目的观察成都市城区健康人群骨密度变化规律,建立该型骨密度仪成都地区骨密度正常值,为骨质疏松诊断、防治提供参考依据。方法①采用EXPERT-XL双能X线骨密度仪(美国 LUNAR公司生产)测定成都市城区健康体检者771例,其中男性300例,女性471例,测量部位包括腰椎1~4和髋部;②按年龄、性别分别输入数据,以10岁为一年龄组,分别计算各组骨密度值,结果以x-±s表示。结果男性腰椎及股骨近端骨密度峰值出现在30~39岁,女性腰椎及股骨近端骨密度峰值出现在20~29岁,随着年龄增加,骨密度逐渐降低,男性在70岁后腰椎骨密度有反弹,而女性在50~59岁间骨密度下降迅速。结论本组健康人群骨密度数据将为成都地区骨质疏松诊断、防治提供参考依据;分析男性腰椎骨密度时应结合股骨近端骨密度;女性50岁后应注意预防、治疗骨质疏松,男性骨质疏松不容忽视。
Objective To analyze the changes of the bone mineral density (BMD) in the healthy population in Chengdu and define the normal range of BMD for diagnosis and treatment of osteoporosis. Methods (1) BMDs of lumbar spine and proximal femur were measured by dual energy X-ray ab-sorptiometry (DXA) in 771 normal subjects (300 men and 471 women) aged 20-100. (2)BMD values were analyzed by different age group in 10 years interval. Results The peak bone mass (PBM) of male and female were in the age groups of 30-39 and 20-29, respectively; BMDs declined with the age increase, except the 70-79 age-group in male; A remarkable decrease in BMD was shown in the 50-59 age group in women. Conclusions This study provides references in diagnosing and managing osteoporosis; BMD of the femur should be taken into account while analyzing the BMD of vertebrae in men; Prevention and treatment of osteoporosis are very important in both women after 50 years old and men.
