体重指数与骨量减少或骨质疏松发病率关系的探讨

摘要

目的：探讨体重指数(BMI)对骨量减少和骨质疏松发病率的影响。方法：对1668例行骨密度测量的健康体检者按BMI分为体重偏低、体重正常、超重、肥胖四组。比较各组间骨量减少或骨质疏松的发生情况。结果：随着体重指数的增高，骨量减少或骨质疏松的患病率降低(P<0.01)，女性绝经后与绝经前比，骨量减少或骨质疏松的患病率显著增高。结论：体重偏低者、特别是体重偏低的绝经后女性更易患骨质疏松，应加强体重偏低者(特别是体重偏低的绝经后女性)对骨质疏松的诊断、治疗和预防，早期干预，以避免骨折的发生。%Objective:To investigate the effect of BMI on morbidity of osteopenia or osteoporosis,Methods:Bone mineral density (BMD was measured by dual energy X-ray absorptiometry in 1668 physical examination person, and all the person were divided into low BMI group , normal BMI group, overweight group and fat group according to their BMI.Results:The morbidity of osteopenia or osteoporosis reduced with BMI increasing (P<0.01), the morbidity of osteopenia or osteoporosis of post menopause is significantly higher than premenopause. Conclusions:BMI is one of the most important factors effect the morbidity of osteopenia or osteoporosis, low BMI ,especially low BMI of the women of post menopause,are more likely suffer osteopenia or osteoporosis. We shoud strengthen the diagnose、treatment and prevent of osteopenia or osteoporosis especially low BMI of the women of post menopause and beneficial to early intervention to avoid fracture.
