摘　　要：目的：调查秦皇岛市第一医院就诊的老年人骨密度及其与体质量指数的关系。方法应用双能 X 线骨密度仪对入选的898例（男415例，女483例）60～94岁人群进行左侧股骨颈、ward’s 三角、大粗隆及腰椎的骨密度测定，按5岁为1年龄组，统计其骨质疏松发生率，记录年龄、身高、体质量，计算体质量指数。结果60～64．9岁年龄组及90岁以上年龄组男女骨质疏松发生率分别为8．2％（4／49）、18．5％（15／81）和80．0％（4／5）、100％（6／6），差异无统计学意义（P ＞0．05）；65～69．9岁年龄组男女骨质疏松发生率11．3％（7／62）、27．1％（16／59），70～74．9岁25．3％（20／83）、42．6％（46／108），75～79．9岁22．8％（21／92）、67．3％（68／101），80～84．9岁33．7％（29／86）、79．5％（62／78），85～89．9岁60．5％（23／38）、88．0％（44／50），差异均有统计学意义（P ＜0．01）。体质量及体质量指数与左侧股骨颈、ward’s 三角、大粗隆及腰椎1～4骨密度呈正相关（P ＜0．01），而年龄与左侧股骨颈、ward’s 三角、大粗隆骨密度呈负相关（P ＜0．01）。结论随着年龄增加男女性骨质疏松发生率逐渐增加，65～89．9岁女性骨质疏松发生率明显高于男性，体质量及体质量指数是骨质疏松的保护因素。ABSTRACT：Objective To investigate the bone mineral density（BMD）of the old people in Qinhuangdao city and its relationship with body mass index（BMI）.Methods The BMD at the left femoral neck,ward’s,greater trochanter and lumbar vertebrae of 898 subjects （415 males and 483 females）aged from 60 to 94 years were detected by dual-energy X-ray absorptiometry（DEXA）.The subjects were divided into different groups based on every 5-year old segment.The incidence of osteoporosis and BMI of each group were calculated and analyzed.Results The incidence of osteoporosis was 8.2%（4/49）in males and 18.5%（15/81）in females in the group aged from 60 to 64.9 years and 80.0%（4/5）in males and 100%（6/6）in females in the group over than 90 years old,showing no significant difference between males and in females in two groups （both P 〉0.05）.In the group aged from 65 to 69.9 years,the incidence of osteoporosis was 11.3%（7/62）in males and 27.1%（16/59）in females;in the group aged from 70 to 74.9 years,it was 25.3%（20/83）in males and 42.6%（46/108）in females;in the group aged from 75 to 79.9 years,it was 22.8%（21/92）in males and 67.3%（68/101）in females;in the group aged from 80 to 84.9 years,it was 33.7%（29/86）in males and 79.5%（62/78）in females and in the group aged from 85 to 89.9 years,it was 60.5%（23/38）in males and 88.0%（44/50）in females.There were significant differences between males and in females all the latter groups （all P〈0.05 ）.The BMD at the left femoral neck,ward’s,greater trochanter and lumbar vertebrae were positively correlated with body mass and BMI,but the BMD at the left femoral neck,ward’s,greater trochanter were negatively correlated with age.Conclusion The incidence of osteoporosis increases with the age in both males and females.It is higher in females than in males （aged from 65 to 89.9 years）.Body mass and BMI are two protective factors of osteoporosis.
