| 目的 调查吉林省长春地区 4613 例 25 ～79 岁女性腰椎正位 L1-L4 TOTAL 骨密度(BMD)，分析长春地区女性骨质疏松患病率，研究女性腰椎 BMD 与年龄、绝经年限、体重指数的相关关系。方法 采用美国 Hologic 公司 Discovery WA 型骨密度仪检测受试者腰椎正位 L1-L4 TOTAL 骨密度。将 4613 例受试者腰椎 BMD 检测结果按 5 岁为一年龄段分组，应用 SPSS19. 0 统计学分析软件进行分析。腰椎 BMD 和骨质疏松患病率与年龄、绝经年限、体重指数的相关性采用直线相关分析。结果 30 岁以后，随着年龄增长，腰椎 BMD 值呈下降趋势，骨质疏松患病率高，年龄与腰椎 BMD 呈负相关，与 OP 患病率呈正相关;随绝经年限延长，BMD 值降低，OP 患病率升高，绝经年限与腰椎 BMD 呈负相关，与 OP 患病率呈正相关。低体重指数组，腰椎 BMD 值最低，OP 患病率最高;随体重指数增加，腰椎 BMD 增加，骨质疏松患病率降低，体重指数与腰椎 BMD 呈正相关，与骨质疏松患病率呈负相关。结论 年龄、绝经年限、体重指数是骨密度的重要影响因素，增龄、绝经年限延长与低体重指数是骨质疏松发生的危险因素。 |

| Abstract: Objective To investigate bone mineral density (BMD) of the total lumbar spine L1-L4 of 4613 25-79-year-old
females in Changchun，Jilin，to analyze the incidence of osteoporosis，and to study the correlation among lumbar spine bone BMD，
age，menopausal year，and body mass index (BMI)． Methods BMD of the total lumbar spine L1-L4 was detected using a
detector (Discovery-WA，Hologic，USA)． The BMD results of 4613 cases were grouped according to a 5-year age division． Data
were statistically analyzed using a SPSS 19. 0 software． Ｒesults Lumbar spine BMD decreased along with age after 30 years old，
and the incidence of osteoporosis increased． The age was negatively correlated with lumbar spine BMD，and positively correlated
with the incidence of osteoporosis． With the prolong of menopausal years，BMD decreased，and the incidence of osteoporosis
increased． The menopausal year was negatively correlated with lumbar spine BMD and positively correlated with the incidence of
osteoporosis． In the low BMI group，the lumbar spine BMD was the lowest，and the incidence of osteoporosis was the highest．
With the increase of BMI，the lumbar spine BMD increased，and the incidence of osteoporosis reduced． BMI was positively
correlated with the lumbar spine BMD and was negatively correlated with incidence of osteoporosis． Conclusion Age，menopausal
year，and BMI were important influential factors of BMD． Aging，delay of menopausal year，and lower BMI were the risk factors
of osteoporosis． |
