摘　　要：目的探索广场舞对不同年龄段绝经后妇女腰椎骨密度(LBMD)的影响,为指导广场舞预防绝经后妇女骨质疏松问题提供参考依据。方法本研究设计为前瞻性队列研究,招募250名西安市绝经后中老年妇女,其中广场舞组170例,非运动组80例。广场舞组人群维持广场舞运动习惯,非运动组保持不运动的习惯,6个月后对两组人群进行LBMD检测。以似然比检验分析广场舞与年龄分级(45~65岁及>65岁)对LBMD的交互作用后按年龄分级进行亚组分析,并通过倾向性评分匹配校正年龄亚组内广场舞组与非运动组的组间混杂因素,最后通过校正匹配后的数据分析广场舞对不同年龄亚组内绝经后妇女LBMD的影响。结果在45~65岁绝经后妇女中,6个月后广场舞组测量LBMD均值高于非运动组,组间差异均有统计学意义(P=0.006);在>65岁的绝经后妇女中,6个月后广场舞组与非运动组的LBMD均值差异无统计学意义(P=0.149)。结论在45~65岁的人群中,广场舞能有效改善中年绝经后妇女的LBMD,在>65岁的老年绝经后妇女中,广场舞对参与者LBMD的改善效果不明显。Objective To explore the effect of square dance on lumbar spine bone mineral density(LBMD)in postmenopausal women of different ages,so as to provide reference basis for guiding square dance to prevent osteoporosis in postmenopausal women.Methods This study was designed as a prospective cohort study,recruiting 250 postmenopausal middle-aged and elderly women in Xi an,including 170 in the square dance group and 80 in the non-exercise group.The square dance group maintained the exercise habit of square dance,while the non-exercise group maintained the exercise habit of not exercising.LBMD testing was performed on both groups after 6 months.The interaction between square dance and age classification(4565 years old and>65 years old)on LBMD was analyzed by likelihood ratio test,and the confounding factors between square dance group and non-exercise group in age subgroup were corrected by propensity score matching.Finally,the effects of square dance on LBMD in postmenopausal women of different ages were analyzed by corrected matching data.Results Among postmenopausal women aged 4565 years old,the mean LBMD measured in the square dance group was higher than that in the non-exercise group after 6 months,and the differences between groups were statistically significant(P=0.006).Among postmenopausal women aged>65 years old,there was no statistically significant difference in the mean LBMD between the square dance group and the non-exercise group after 6 months(P=0.149).Conclusion Square dance is effective in improving LBMD in middle-aged postmenopausal women aged 4565 years old,but not in elderly postmenopausal women aged>65 years old.
