机关工作人员骨密度现状调查及其影响因素分析和风险评估

Investigation on the Current Situation of Office workers' BMD and Its Influencing Factor Analysis and Risk Assessment

目的:调查与分析4364名不同性别、年龄机关工作人员的骨密度现状及其影响因素和风险评估。研究方法:测试法;问卷调查法,数理统计法。结果:1.BQI、T值男、女均随年龄增加呈降低趋势(P<0.001),随BMI增大呈升高趋势(P<0.001);男、女BQI均值分别为92.55±17.63、87.41±15.43,T值分别为-.972±1.47,-.425±1.54。2.骨质流失和骨质疏松两者合计检出率男、女分别达55.8%和40.1%;45岁前男、女均随年龄增长而增加(P<0.001),并随BMI值增大而降低(P<0.001)。3.Logistic回归分析显示,性别、年龄、BMI、上班步行、周运动频率、食用牛奶、偏食与骨质疏松症的发生高度相关(P<0.01)。结论:1.机关工作人员的骨质强度和骨密度随年龄的增加而降低,随BMI的增大而提高。2.机关工作人员缺钙、骨质流失现象严重;年轻人未达到良好骨峰值。3.性别、BMI、上班步行、周运动频率、食用牛奶系骨密度的保护因素;年龄、偏食为骨密度的危险因素;偏食、上班步行和年龄的优势比突出,与骨质疏松的关联度更高。

Objective：The paper is to survey and analyze of status of bone mineral density of 4364 government staff of different genders, ages, and its influencing factors and risks assessment. Method： Test, questionnaire investigation and statistic method are adopted. Results：1. Both males and females undergo a trend of decrease of BQI. The T value decreases with ages （P〈0. 001） and increases with the increasing of BMI（P〈0. 001）. The mean value of BQI is 92. 55＆#177;17 . 63 for men and 87 . 41＆#177;15 . 43 for women and the mean value of T value is -0 . 972＆#177;1 . 47 and -0 . 425＆#177;1 . 54 re-spectively . 2 . The combined detection rate of bone loss and osteoporosis in male and female was 55 . 8% and 55 . 8% re-spectively. Before the age of 45 , the rate in both male and female increases with the age （P〈0. 001） and decreases along the increase of BMI（P〈0. 001）. 3. The logistic regression analysis indicates that osteoporosis is correlated to sex, ages, BMI, going to work on foot, the frequency of weekly exercise, milk taking and food preference. Conclusion：1. The bone strength and bone mineral density in office workers decrease with age and increase with the increasing of BMI. 2. Civil servants suffer a severe situation of lacking calcium and bone losing, which takes a great proportion in the bone mineral density problem （ male 55 . 8%, female 40 . 1%） . The peak of bone mineral density in young civil servants is not good. 3. Gender, BMI, walking to work, the frequency of weekly exercises and milk taking are the protective factors of the bone mineral density. Age, food partiality are the risk factors. The advantage of food partiality, walking to work age is more outstanding,and correlation to osteoporosis is thus higher.
