目的 了解海宁市成人骨量的分布规律及骨质疏松症的患病情况。方法 采用DOVE3 0 0 0骨密度测量仪对 3 3 65例对象的跟骨骨量进行测定 ,SPSS统计软件对各组数据进行处理。结果 海宁市成人骨量约在 2 5～ 3 5岁达到峰值 ,5 0岁开始随年龄的增加而逐年减少 ;骨质疏松症的发病率与年龄的变化呈正相关 (r=0 82 3 ) ;在 5 0岁前男性骨量虽比女性高 ,但两者比较无统计学差别 (P >O 0 5 ) ,5 0岁后男性明显高于女性 (P <0 0 5 ) ,且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 15年后趋缓。结论 海宁市成人骨量 2 5～ 3 5岁达到峰值 ;女性骨量低于男性 ,5 0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 understand the distribution of adult bone mass and the prevalence of osteoporosis in Haining City. Methods Calcaneal bone mass of 3365 subjects was measured by DOVE3000 bone density meter. SPSS statistical software was used to process each group of data. Results The bone mass of adults in Haining city peaked at about 25-55 years and decreased gradually with the increase of age at the age of 50 years. The incidence of osteoporosis was positively correlated with age (r = 0.823). The bone mass of males was higher than that of females before the age of 50, but there was no significant difference between the two groups (P> O 0 5). After the age of 50 males were significantly higher than females (P 0 05) Of the rate of loss was significantly faster than men; women 1 to 3 years after bone mass began to lose rapidly, about 15 years later slowed down. Conclusions The bone mass of adults in Haining City reaches the peak at 25 ~ 35 years old. The bone mass of females is lower than that of males. The rate of bone loss after 50 years is obviously faster than that of males. The loss of females is closely related to the time of menopause
