北京郊区不同职业人群的前臂远端骨密度对比分析

Beijing suburb of different occupations in the distal forearm bone mineral density comparative analysis

目的：探讨不同职业人群的骨密度的变化规律和骨质疏松症的发病率。方法整理在本院做骨密度检查的体检人群，按职业特点进行职业分类，每十岁为一年龄段分组。运用多因素方差分析不同职业人群、不同年龄组骨密度值进行均值比较、运用卡方检验比较各组骨质疏松症患病率的差异。结果男女不同职业人群骨密度的峰值骨量均出现在30～39岁，且铁矿职工最高、农民最低、公务员及医务人员居中；骨质疏松症的发病率有明显差异，铁矿职工最低、农民最高、公务员及医务人居中，男性为：农民32％、公务员9％、医务人员8％、铁矿职工1％（P＜0.01）；女性为：农民19％、公务员8％、医务人员5％、铁矿职工1％（ P ＜0.01）。结论铁矿职工骨质疏松症发病率最低，农民最高，公务员及医务人居中。骨质疏松症发生率与职业有关，主要受环境因素影响。

Objective To investigate the incidence of different occupations variation in BMD and osteoporosis.Methods Finishing in the hospital to do bone density examination population, by occupational characteristics of occupational classification, each age group aged one.Multivariate analysis of variance of the four occupations mean of BMD of different age groups were compared using the chi-square test to compare the differences in each group the prevalence of osteoporosis.Results The results of four different professional men and women between the peak bone mineral density in volume of 30 to 39 years, and the highest iron workers, peasants minimum, civil servants and medical staff center.The incidence of osteoporosis were significantly different, iron workers, minimum, maximum farmers, civil servants and medical staff center; males： 32% of the farmers, 9% of civil servants, medical staff by 8%, iron miners 1%;women： 19% of farmers, civil servants 8%, 5% of the medical staff, iron workers 1% （P 〈0.01 ）.Conclusion Iron workers lowest incidence of osteoporosis, highest farmer, civil servants and medical staff center. Osteoporosis and career-related, but mainly affected by environmental factors.
