交谊舞运动对中老年人骨密度及平衡机能影响的流行病学研究

An Epidemiological Study on the Effects of Social Dance on Bone Mineral Density in the Crowd of Middle-Aged and Older

运用流行病学研究方法探讨了交谊舞运动对中老年人骨密度及平衡机能的影响。实验组中骨量减少者少于对照组(OR=1.9,95%,C I=1.1-3.1),当控制调整其它因素后综合评价时发现交谊舞运动者骨量减少相对较小,60岁以上老年人交谊舞组的平衡机能明显优于对照组。

An epidemiological study is used to investigate the effects of social dance on bone mineral density in the crowd of middle-aged and older. The results shows that dance group had a significantly lower proportion in the loss of bone mineral density than that of in control group, （OR=1.9, 95% confidence interval=1.1-3.1） after adjusted for several synthetical factors, dance group also shows a trend toward lower proportion in the losing of BMD. Balance mech- anism of older who aged 60 or above have predominant than control group.
