对5个不同膳食习惯地区的655名45～75岁中、老年城市居民、农民、渔民和牧民跟骨X光片的跟骨小梁的分布及密度进行分级评定。跟骨小梁密度(骨密度)分为5级。结果市民的骨密度最高,渔民次之,农民最低。男性比女性的骨密度高,骨密度随年龄的增加而降低。体质指数(BMI)与骨密度呈正相关;膳食中动物性食物的摄入量与骨密度有显著正相关。X光片跟骨小梁密度分级判定法可以作为估计人群骨质疏松盛行状况的参考指标。
The distribution and density of 655 calcaneal trabeculae in 655 middle-aged and aged urban residents, peasants, fishermen and herdsmen in 45 different areas with different dietary habitats were graded. Trabecular bone density (bone density) is divided into five levels. The results of the public’s highest bone mineral density, followed by fishermen, farmers the lowest. Men than women, high bone density, bone density decreased with increasing age. Body mass index (BMI) and bone mineral density were positively correlated; dietary intake of animal food and bone mineral density had a significant positive correlation. X-ray calcaneal trabecular meshwork density grading method can be used as a reference to estimate the prevalence of osteoporosis in the population.
