摘　　要：对上海市区居民３０５１人进行了跟骨骨密度测定。其中男１４４４人，女１６０７人，年龄１１～９５岁，按５岁为一年龄组将其分为１７组。结果：跟骨骨峰值出现在２０～２４岁组，女性骨峰值显著小于男性，中年开始出现跟骨骨量丢失，女性的骨丢失速度显著快于男性。女性骨累积丢失量也显著大于男性。女性的跟骨累积丢失量仅次于Ｗａｒｄ三角。跟骨骨密度除了随年龄变化外，也受身高、体重及体重指数的影响。６０岁以上老年女性骨质疏松症的患病率显著高于男性，男、女分别为１３．９％、５８．０％。Bone mineral density in the calcaneus was measured in 3051 Shanghai residents(1444 men, 1607 women,aged from 11 to 95). The population was divided into 17 age groups. The cross-section study showed that the peak bone mass of the calcaneus occurred in the age group of 20-24 years old. The value of peak bone mass in women was lower than that in men. Bone loss began at middle age. The bone loss rate was faster in women than in men. The accumulated amount of bone loss in the calcaneus was larger in women than in men ,and was only less than Ward's triangle in women. The bone density of the calcaneus was affected by age, weight and height. The prevalence rate of osteoporosis in old people(age>=60)was 58% in women and 14% in men. It is concluded that the calcaneus is a satisfactory site for measurement. The reference data in this study will. be helpful in assessing bone mass in Chinese people suspected of suffering from osteoporosis.
