广场舞对绝经女性骨密度和性激素水平的影响

Effect of square dance on bone mineral density and female hormones in postmenopausal women

目的探讨广场舞对绝经妇女骨密度和性激素水平的影响。方法选择30名连续跳广场舞3年以上（平均每周3~4次以上）的绝经妇女为实验组,另选30名不跳舞的绝经妇女为对照组,比较两组骨密度、T-Score值及血清雌二醇、孕酮、黄体生成素水平。结果实验组骨密度及血清雌二醇、孕酮水平均明显高于对照组（P〈0.05）,两组的TScore值差异也有统计学意义（P〈0.01）。结论广场舞可延缓绝经后妇女骨量丢失,可能与提高绝经后妇女性激素水平有关。

Objective To study the effect of square dance on bone mineral density （BMD） and female hormones in postmenopausal women. Methods BMD, T-Score, and serum levels of estradiol, progesterone and luteinizing hormone were compared between 30 postmenopausal women （observation group） with continuous square dance for more than 3 years （3- 4 times weekly） and 30 controls without square dance （control group）. Results BMD and serum estradiol and luteinizing hormone levels were higher in observation group than in control group （P〈0.05）. There was also a significant difference in T-Score between both groups （P〈0.01）. Conclusion Square dance can delay the bone mass loss in postmenopausal women possibly through the improvement of female hormone level.
