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 bone mineral density (BMD) in 2820 healthy adults aged from 1 to 80 years in Kunming was analyzed. The changes of BMD with age were as follows: before 30 years old, and reached the peak between 30 and 39 (male 0755 ± 0101, female 0 678 ± 0067), after 40 years of age decreased, the average annual bone mineralization rate and bone peak male> female, the average annual rate of female bone loss> male, the difference was significant. The fastest rise in adolescent BMD, female early male 2 years. Women’s menopause 5 to 10 years to accelerate the loss of bone, which is 7 times before, men with slow bone loss, 75-year-old has been accelerated. The cumulative incidence of total bone loss for 40 years was 17.48% male and 34.07% female. The prevalence of osteoporosis in middle-aged and elderly people aged over 50 was 4.21% male and 26.19% female (1:6 22). This group of men and women bone peak value and the average of 13 provinces and cities across the country but higher than most of the northern group, which is related to Kunming and the geographical environment.
