Objective To investigate the bone mineral density (BMD) of special printing industry population and analyze its influencing factors. Methods 159 employees in a bill printing factory were enrolled in this study. The questionnaire was used to collect the general information. Omnisense7000 bone densitometry was used to obtain Tscore of BMD. Tscore of employees with different characteristics were compared using two sample t test and oneway ANOVA. The effects of investigating factors on BMD were analyzed using ordered logistic regression. Results Tscore of average BMD of 159 employees was0.65±1.10. Gender, age, parents underwent osteoporosis, insolation, and smoking affected Tscore of BMD significantly (P＜0.05). The ordered Logistic regression analysis of 16 facts ( gender, age, parents underwent osteoporosis, smoking and so on) showed that gender and insolation were the influencing factors (P＜0.05). Conclusion The Tscore of BMD in special printing industry population decreased which was affected by gender and insolation.
