摘要
分析昆明地区2820例1~80岁健康人桡尺骨骨密度(BMD),发现BMD随年龄的变化规律为:30岁前上升,30~39岁达高峰(男0755±0101、女0678±0067),40岁后下降,年均增骨率及骨峰值男>女、年均失骨率女>男,差异均非常显著。青春期BMD上升最快,女早男2年。妇女绝经5~10年间失骨加速,是此前的7倍,男性失骨缓慢,75岁后有所加快。累积40年总失骨率男1748%、女3407%,50岁以上中老年骨质疏松患病率男421%、女2619%(1∶622)。本组男女骨峰值与全国十三省市平均值相近而高于多数北方组,后者与昆明的地理环境因素有关。
The changes of regularity with age of bone mineral density (BMD) in ulna and radius of 2820 subjects aged 1-80 years in Kunming region were assesssed The peak values of BMD for both male and female were in 30-39 years old The average rise rate per year and peak value of BMD in male were more than that in female, and average loss rate of BMD per year in male was lower than that in female The total loss rate of BMD on 40 years was 17 48% in male, and 34 07% in female In over 50 years old subjects, the incidence of osteoporosis was 4 21% in male and 26 19% in female
