Abstract: 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±17.63 for men and 87.41±15.43 for women and the mean value of T value is -0.972±1.47 and -0.425±1.54 respectively. 2. The combined detection rate of bone loss and osteoporosis in male and female was 55.8% and 55.8% respectively. 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.
