摘　　要：目的了解本市社区老年人群体重指数(BMI)与骨质疏松症(OP)发病的关系,为本地区OP的防治提供参考。方法使用美国Norland公司生产的XR-600双能X线骨密度仪对180例老年人正位腰椎和左股骨近端进行骨密度测定,并对各个因素与骨密度之间的相关性进行分析。结果 Spearman相关分析结果显示,年龄、绝经年龄、吸烟与骨密度呈负相关,BMI、服用钙剂、服用维生素D与骨密度呈正相关,且年龄、BMI差异最为显著;180例受试者中,体质量过低、正常、超重三者OP发生比率比较,差异有统计学意义(χ2=11.297,P<0.01)。结论本地区老年人群OP发病率与目前BMI呈负相关,老年人要合理适当地饮食,保持正常体质量,有效地减少发生骨质疏松的危险因素。Objective To elucidate the relationship between BMI and osteoporosis in aged people, so as to provide the reference for prevention and cure of OP of the region. Methods Bone density in lumbar spine and left proximal femur were measured in 180 aged patients used Norland XR - 600 dual energy X - ray absorptiometry and the relevancy between each factor and bone mineral density（BMD） was analyzed. Results Spearman correlation analysis showed that the age, menopausal age and smoking were negatively correlated with BMD; BMI, calcium and vitamin D were positively correlated with BMD. Age and BMI had significant difference. The difference of OP incidence rate in 180 subjects with too low, normal and overweight body mass was statistically significant （X^2 = 11. 297,P〈0. 01）. Conclusion The incidence of OP in the local elderly population is negatively correlated with BMI, the elder should be reasonable and proper diet, maintain a normal body weight, effectively reduce the risk factors for osteoporosis.
