摘　　要：目的　调查分析身高、体重及体重指数 (BMI)对辽宁地区正常中老年人群骨矿含量的影响。方法　在辽宁地区年龄在 40～ 79岁的中老年人群中随机抽样 173 1例 ,除外可能导致继发性骨质疏松症的各种疾病 ,应用美国lunar公司生产的双能X线骨密度仪 ,分别测试受试者的腰椎及股骨上段的骨密度 (BMD) ,全部资料输入微机 ,用SPSS软件进行统计学处理。结果　身高与腰椎及股骨上段的BMD相关性较差 (r=0 0 87～ 0 197,P <0 0 5 ) ,体重与腰椎及股骨上段的BMD相关性较好(r=0 2 2 6～ 0 3 5 2P <0 0 1)。体重指数与腰椎的相关性最好 ,其次是大转子。腰椎及股骨颈的BMD在超体重组 (BMI>2 5kg/m2 )明显大于低体重组 (BMI≤ 19kg/m2 ) ,其差异有显著性 ,该特点在腰椎最为明显。结论　体重是影响中老年人骨矿含量的重要因素。对低体重的中老年人 (BMI≤ 19kg/m2 )可作为骨质疏松症的易发人群 ,及时监测BMD 。Objective To study the effect of height,weight and body mass index (BMI) on bone mineral density (BMD) in middle age and old people in Liaoning Province Methods 1731 subjects aged 40 79 who were excluded the diseases that can cause secondary osteoporosis were obtained in Liaoning Province,their BMD of L 2-4 and upper femur were measured by Lunar DPX L dual energy X ray absorptiometry,then statistically analyzed with SPSS software Results Height is less related with BMD in L 2-4 and upper femur ( r =0 087 0 197 P <0 05) Wight is better related with BMD in L 2-4 and upper femur ( r =0 226 0 352, P <0 01) BMI is closely correlated with BMD in L 2-4 , next is troch and femur neck The BMD of L 2-4 and femur neck in BMI>25 kg/m 2 group is much higher than that in BMI≤19 kg/m 2 group ( P <0 01),especially in L 2-4 Conclusion Weight is one of most important factors that affect the bone mineral content in middle age and old people The low BMI people (BMI≤19 kg/m 2) are subject to osteoporosis, their BMD should be measured on time to prevent osteoporosis
