北京郊区成年人桡骨远端骨密度调查分析(1)
[摘要] 目的 通過测量北京大兴区、密云地区成年人的桡骨远端骨密度，分析比较北京南北郊区成年人在各年龄段的骨密度差异及随年龄变化规律。 方法 采用美国DTX-200型双能X线骨密度仪，检测北京大兴区成年男性1040例、女性1892例，密云地区成年男性780例、女性423例的非优势前臂桡骨远端1/3处的骨密度，记录BMD值。将检测结果按地区、性别、年龄段分组(每10岁为1个年龄组，分为7个年龄组)。采用两独立样本t检验分别比较同地区、同年龄段成年人的桡骨远端骨密度在性别间的差异，分别比较同性别、同年龄段成年人的桡骨远端骨密度在北京南北郊区间的差异，分析两地区成年男性、成年女性骨密度随年龄变化趋势。 结果 大兴区、密云地区成年人在各年龄段的桡骨远端骨密度BMD均值男性均大于女性，且差异有统计学意义(P<0.05)；大兴区60～69岁年龄段男性、50～59岁年龄组女性的桡骨远端骨密度BMD均值低于密云地区，差异有统计学意义(P<0.05)；北京大兴区其他各年龄段女性BMD均值略低于或接近于密云地区，但差异均无统计学意义(P>0.05)。北京大兴区、密云地区成年男性、成年女性桡骨远端骨密度BMD峰值均出现在30～49岁年龄段间，且BMD均值随年龄增高而逐步降低。 结论 密云地区人群整体骨量稍高于大兴区，但骨质疏松的发生情况两地区差异不明显。大兴区、密云地区人群中的50岁以后中老年人群，尤其女性更易发生骨质疏松，应给予适当预防和治疗措施。

[Abstract] Objective To analyze and compare the differences in bone mineral density among adults in north and south suburbs of Beijing and the change regular pattern of bone mineral density with age by measuring the bone mineral density of the distal radius of adults in Daxing District and Miyun area. Methods The bone density of the distal 1/3 of non-dominant forearm radius in 1040 adult males and 1892 females in Daxing District of Beijing， 780 adult males and 423 females in Miyun area were measured by the United States DTX-200 dual-energy X-ray absorptiometry， and the BMD values were recorded. The test results were grouped by region， sex and age (1 age group per 10 years， divided into 7 age groups). Two independent samples t test was used to compare the differences in distal radius bone mineral density between gender in the same area and the same age group， and to compare the differences in distal radius bone mineral density between the north and south suburbs in the same gender and the same age group. The changes of bone mineral density (BMD) in adult males and adult females of the two areas were analyzed. Results The mean BMD in the distal radius of adults at all ages of males in Daxing District and Miyun area was significantly higher than that in female， and the difference was statistically significant(P<0.05)； The mean BMD in the distal segment of males in the 60-69 years old group and females in the 50-59 age group in the Daxing District was significantly lower than that in the Miyun area， and the difference was significant(P<0.05). The mean BMD of the females in Daxing District at other age groups was slightly lower or close to that in the Miyun area， but the difference was not statistically significant(P> 0.05). The BMD peak of bone mineral density in adult males and females in Daxing District and Miyun area of Beijing was between 30 and 49 years old， and the mean BMD was gradually decreased with age. Conclusion The bone mass of the population in Miyun area is slightly higher than that in Daxing area， but there is no obvious difference in the incidence of osteoporosis between the two regions. The elderly after 50 years of age in Daxing District and Miyun area， especially women， are more prone to osteoporosis， and should be given appropriate prevention and treatment measures., http://www.100md.com(郭勇 栗敏 杨鸿兵)
