目的 :了解福建省健康人群峰值骨量 ( PBM)的基本情况 ,为骨质疏松症 ( OP)的防治提供依据。方法 :选取福州市 2 5～ 45岁健康人群共 2 46人 ,用双能 X线骨密度仪 ( DEXA)测定前臂远端的骨密度 ( BMD) ;选取漳州市 2 5～ 5 0岁健康人群共 3 0 0人 ,用超声骨密度仪测定足跟的 PBM;选取泉州市健康女性人群共 3 0 2人 ,用 DEXA测量腰椎 ( L2 ～ L4 )正位及股骨近端 ( Neck,Ward’ s,Troch) BMD。结果 :男性和女性前臂远端PBM均在 3 0～ 3 4岁年龄组 ,其中男性 BMD为 0 .5 77± 0 .0 61 g/cm2 ,女性 BMD为 0 .496± 0 .0 3 7g/cm2。男性、女性足跟峰值 PBM均在 3 5～ 3 9岁年龄组。男性 BUN峰值为 78.87± 6.0 8db/MHz,SOS峰值为 1 5 2 8.88± 3 5 .60 M/S,STI峰值为 98.5 1± 7.90 % ;女性 BUN峰值为 73 .2 3± 8.3 4db/MHz,SOS峰值为 1 5 2 2 .97±3 4.91 M/S,STI峰值为 93 .3 7± 8.2 0 %。女性腰椎 ( L2 ～ L4 )和股骨近端 ( Neck,Ward’ s,Troch)的 PMD均见于3 5岁～ 3 9岁年龄组 ,分别为 0 .9749± 0 .1 2 43 ,1 .0 449± 0 .1 2 68,1 .0 71 7± 0 .1 3 80 ,0 .875 6± 0 .0 984,0 .80 3 2±0 .1 1 47,0 .73 91± 0 .0 876( g/cm2 )。运动有利于 PBM形成 ,而吸烟和饮酒不利于 PBM形成。结论 :骨骼不同部
Objective: To understand the basic situation of peak bone mass (PBM) in healthy population in Fujian Province, and to provide basis for the prevention and treatment of osteoporosis (OP). Methods: A total of 246 healthy subjects from 25 to 45 years old in Fuzhou city were enrolled in this study. The bone mineral density (BMD) of distal forearm was measured by dual energy X-ray absorptiometry (DEXA) A total of 300 healthy volunteers were enrolled in this study. The heel PBM was measured by ultrasonic bone densitometry. A total of 302 healthy female population were enrolled in Quanzhou. The densities of lumbar spine (L2 ~ L4) and proximal femur (Neck, Ward’s , Troch) BMD. Results: The distal PBM of male and female forearm were all in the range of 30 to 34 years old, in which the male BMD was 0.577 ± 0.061 g / cm 2 and the female BMD was 0.496 ± 0.30 7g / cm2. Male and female heel peak PBM are in the 35 ~ 39 age group. The peak of BUN in male was 78.87 ± 6.0 8db / MHz, the peak value of SOS was 1528.88 ± 35.560 M / S, the peak value of STI was 98.5 1 ± 7.90%, the peak value of female BUN was 73.223 ± 8.3 4db / MHz, The SOS peak value was 1 522 2 .97 ± 3 4.91 M / S and the STI peak value was 93.37 ± 8.2 0%. The PMD of female lumbar (L2 ~ L4) and proximal femur (Neck, Ward ’s, Troch) were all found in the age groups from 35 to 39 years old, which were 0.9749 ± 0.1243 and 1.0449 ± 0 .1 2 68,1 .0 71 7 ± 0 .1 3 80, 0 .875 6 ± 0 .0 984,0 .80 3 2 ± 0 .1 1 47,0 .73 91 ± 0 .0 876 (g / cm2). Exercise is beneficial to PBM formation, while smoking and drinking adversely affect PBM formation. Conclusion: different parts of the skeleton
