摘　　要：目的探讨浙江地区人群骨量的分布规律和骨质疏松的患病情况。方法采用美国进口Dove3000骨密度测量仪对11926例浙江居民的跟骨骨量进行测定,按年龄分成14组,SPSS10.0统计软件对各组数据进行处理。结果浙江地区人群骨量约在25～35岁达到峰值,50岁开始随年龄的增加而逐年减少;20岁后男性骨密度明显高于女性（P〈0.01）,女性骨量的丢失速率明显快于男性;女性绝经1～3年骨量开始快速丢失,约10年后趋缓;骨质疏松的患病率与年龄的变化呈正相关（r=0.99）,女性患病率明显高于男性（P〈0.01）。结论浙江地区人群骨量25～35岁达到峰值,50岁后随年龄的增加而逐年减少;女性骨量低于男性,50岁后骨量丢失的速率明显快于男性;女性骨量丢失与绝经时间密切相关。Objective To explore the bone mineral density（BMD） regularity and the osteoporosis condition in Zhejiang residents of our country. Methods BMD in the calcaneus was measured in 11926 Zhejiang residents with Dove3000 OsteoAnalyzer. The population was divided into 14 age groups. Data were analyzed with SPSS10.0 software. Results The study showed that the peak bone mass of the calcaneus occurred in the age group of 25-35 years old. The value of bone mass in women was lower than that in men after 20 （ P 〈 0.01 ）. Bone loss began at 50. The bone loss rate in women was faster than in men and manifestly faster from 1 to 3 years after menopause but slowed down after 10 years. The incidence of osteoporosis was positively related to the age（ r=0.99）and markedly higher in women than in men（ P 〈 0.01 ）. Conclusions The peak bone mass of Zhejiang residents occurs in the age group of 25-35 years old. The value of bone mass in women is lower than that in men. Bone loss begins at 50. The bone loss rate in women is faster than in men after 50. The bone loss in women is closely related to the postmenopausal period.
