摘要
目的 了解成都地区骨峰值 ( PBM)的基本情况 ,为骨质疏松 ( OP)的防治提供依据。方法 随机抽取成都地区 2 0～ 4 9岁人群除外心肝肺肾、内分泌等慢性病及骨代谢疾病者 368名 ,进行了腰椎 ( L2 -4 )正位和髋部的双能 X线骨密度 ( BMD)的测量。结果 2 0～ 4 9岁人群的 BMD相对稳定 ,男性腰椎骨峰值见于 2 0～ 2 9岁 ,值为1.0 75± 0 .114( g/ cm2 ) ;女性见于 30～ 39岁 ,值为 1.10 6± 0 .113( g/ cm2 ) ;髋部 ( Neck,Ward's,Troch) PBM均见于2 0～ 2 9岁。各年龄组的 BMD男女无差异 ( P>0 .0 5) ,而 L2 -4 BMC(骨矿含量 )及椎体面积 ( AREA)男性均大于女性 ,且存在显著性差异 ( P<0 .0 1) ,BMD城乡无显著差异。成都地区的 PBM略低于北方地区。结论 成都地区男性PBM为 1.0 75± 0 .114( g/ cm2 ) ,女性 PBM为 1.10 6± 0 .113( g/ cm2 ) ;临床表现与 BMD不符时 ,分析 BMD的同时应参照 BMC及 AREA。
Objective To find out the peak bone mass (PBM) in people of Chengdu and provide useful reference data for preventing osteoporosis(OP). Methods Dual\|energy X\|ray bone mineral density(BMD) was investigated randomly for 368 people in Chengdu. Results The BMD is stable in 20~49 year old group,and the PBM of lumbar vertebrae is seen in 20~29 year old group for males and in 30~39 year old group for females. However, the PBM of femoral neck,Ward's triangle and trochanter are found in 20~29 year old group for both sexes. The PBM of females is equal to that of males,but L 2 4 BMC and L 2 4 AREA of females are much lower than those of males. There is no difference between urban district and suburbs. The PBM in people of Chengdu is lower than that in people of North China. Conclusion When we analyze the BMD of vertebrae,we should take into account the BMC and AREA of vertebrae at the same time.
