摘要
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。
Six hundred and fifty five radiographs of calcaneum were taken from city residents, farmers, fishermen and herdsmen aged 45～75 years old living in five areas on different dietary habits. The bone density was evaluated by the trabecular pattern of the calcaneum on radiographs and divided into five grades. The results show that the bone density of city residents is the highest, the bone density of fishermen is in the medium and the bone density of farmers is the lowest. The bone density of male is higher than that of female. The bone density is decreasing with the incrasing of age. Body mass index (BMI)is directly related to bone density. The animal food intake is positively related to bone density. Analysis of bone density on radiographs of the calcaneum is considered to be used as a reference for the estimation of the prevalence of osteoporosis of population in the field study.
