辽西南部健康体检者指骨骨密度的调查研究

Investigation of bone mineral density of the phalanx in healthy people in Southwest region of Liaoning

目的了解辽西南部地区健康成人体检者骨密度现状,为诊断、预防骨质疏松提供科学依据。方法采用MertiscanTM骨密度仪,调查测量了辽西南部地区的1204(男性598,女性606,年龄在20～70岁之间,并按10岁分组)名汉族成人的第2～4手指的平均骨密度。根据T值判定骨量减少和骨质疏松,并计算其发生率。结果 1.指骨骨密度男性平均为0.572 g/cm2,女性平均为0.523 g/cm2,男性明显大于女性并有高度显著性差异(P<0.01)。2.骨量减少发生率男性平均占17.2%,女性平均占17.8%。骨质疏松发生率男性平均占11.4%女性平均占13.2%。结论辽西南部地区男女手指骨密度值处低水平。指骨骨密度值、骨量减少和骨质疏松发生率有明显的性差、年龄差和地区差。

Objective This study investigated the current status of bone mineral density of healthy adults in southwest region of Liaoning province, and provided scientific evidence of diagnosis and prevention for osteoporosis. Methods Mean values of bone mineral density of the 2-4 phalanx were measured in 1204 healthy Han nationality people in Panjin city （598 males and 606 females, aged from 20 to 70 years old, grouped by every 10 years） , using MertiscanTM bone mineral density equipment. Osteopenia and osteoporosis were diagnosed according to T values and the incidences were calculate. Results 1 ） The mean values of bone mineral density in males and female were 0. 572g/cm2and 0. 523g/cm2, respectively, with significant difference （P 〈0.01 ）. 2） Osteopenia rate was 17.2% in the male and 17.8% in the female. Osteoporosis rate was 11.4% in the male and 13.2% in the female. Conclusion The bone mineral density of the phalanx in the male and female in southwest region of Liaoning was at low level. Significant differences of bone mineral density, and ostcopenia and osteoporosis rate existed between the genders, ages and the regions.
