【摘要】：目的了解银川市儿童青少年骨密度及骨矿含量,为促进儿童青少年骨骼发育及预防骨质疏松提供科学依据。方法采用现况研究,运用分层整群抽样方法,在银川市抽取1 614名7~18岁儿童青少年进行问卷调查、体格测量和骨密度及骨矿物质含量测量。结果被试平均全身骨密度为(0.89±0.12)g/cm~2,平均全身骨矿含量为(1 548.40±477.04)g。随着年龄的增加,儿童青少年骨密度和骨矿含量水平均呈上升趋势。男女骨密度和骨矿含量随年龄的变化曲线均出现了"2次交叉",骨密度的第1次交叉在11岁,第2次在15岁;骨矿含量的第1次交叉在10岁,第2次在14岁。且骨密度和骨矿含量的第1次交叉前和第2次交叉后男生均高于女生,差异均有统计学意义(P值均0.05)。回族和汉族儿童青少年骨密度和骨矿含量水平差异均无统计学意义(t值分别为-1.876,-1.838,P值均0.05)。结论银川地区儿童青少年骨密度和骨矿含量随年龄增长而增加并受性别影响。应对儿童青少年定期进行骨密度和骨矿物含量的测量,以及早预防骨质疏松的发生。
[Abstract]:Objective to investigate bone mineral density and bone mineral content of children and adolescents in Yinchuan City, and to provide scientific basis for promoting bone development and preventing osteoporosis. A questionnaire survey was conducted among 1,614 children and adolescents aged 718 years old in Yinchuan City. The results showed that the average BMD and BMD were 0.89 卤0.12 g / cm ~ (-2) and 1 548.40 卤477.04 g / cm ~ (-2) respectively. The changes of bone mineral density and bone mineral content with age showed "two crossover" in male and female, the first cross of bone mineral density was 11 years old, the second time was 15 years old. The first crossover of bone mineral content occurred at the age of 10 and the second at the age of 14. The bone mineral density and bone mineral content before and after the first crossover were higher in boys than in girls. There was no significant difference in bone mineral density (BMD) and bone mineral content (BMD) and bone mineral content (BMD) between children and adolescents of Hui nationality and Han nationality were -1.876 and 1.838 P, respectively. Conclusion the bone mineral density and bone mineral content of children and adolescents in Yinchuan area are 0.050.Conclusion the bone mineral density and bone mineral content of children and adolescents in Yinchuan area are not significantly different. Increased with age and affected by gender. Bone mineral density and bone mineral content should be measured regularly in children and adolescents. And early prevention of osteoporosis.
