摘要
目的探讨日常性体力活动对绝经后妇女骨量的影响。方法将222名绝经后妇女（平均年龄56．51±8．33岁）按体力活动水平分为3类：体力不足、体力活跃、体力高度活跃，比较3组之间腰椎骨密度、骨矿含量和腰椎骨面积。结果不同体力水平之间平均腰椎和第1．4腰椎骨密度值不同（F=10．818，P=0．000；F=11．060，P=0．000；F=7．309，P=0．001；F=11．703，P=0．000；F=12．347，P=0．000），体力高度活跃组平均腰椎和第1～4腰椎骨密度值高于体力不足组和体力活跃组（P分别为0．003、0．006；0．009、0．000；0．015、0．001；0．002、0．000；0．000、0．000），而体力活跃组与体力不足组间差异无统计学意义（P分别为0．986、0．579、0．967、0．942、0．520）。骨矿含量L1、骨矿含量L4在不同体力活动水平间不同（F=4．172，P=0．017；F=3．690，P=0．027），体力不足组骨矿含量L1低于高度活跃组（P=0．006），骨矿含量L4明显低于体力活跃组和高度活跃组（P分别为0．017、0．009）。除L3骨面积无差异（F=2．844，P=0．060）外，其余腰椎L1，L2，L4骨面积在不同体力活动水平间有差异（F=6．478，P=0．002；F=5．370，P=0．005；F=6．197，P=0．1302），体力活跃组腰椎L1，L2，L4骨面积均大于体力不足组和高度活跃组（P分别为0．001、0．005：0．028、0．002；0．028、0．001）。结论体力活动水平与绝经后妇女骨量有关。
Objective To investigate influence of daily physical activities of the postmenopausal women on their BMD, BMC and bone area. Methods 222 postmenopausal women （mean age：56.51±8.33 years old） were divided into 3 groups according their daily physical activity levels： physically inactive group, physically active group and physically vigorously active group. The BMD, BMC and bone area of their vertebrae were compared. Results Mean BMD value of the lumbar vertebrae and BMD values of the first to the forth lumbar vertebrae of the women in different groups were different （ F = 10.818, P = 0.000 ; F = 11. 060, P = 0. 000 ; F = 7. 309, P = 0.001 ; F = 11. 703, P = 0.000;F = 12. 347 ,P = 0.000 respectively）. Of which, the mean BMD value of the lumbar vertebrae and BMD values of the first to the forth lumbar vertebrae of the women in the physically vigorously active group was higher than both that in the other two groups （ P = 0. 003, 0. 006 ;P = 0.009, 0.000; P = 0.015, 0.001 ;P = 0. 002, 0.000 ; P = 0.000, 0.000 respectively）. While in the mean BMD value of the lumbar vertebrae and BMD values of the first to the forth lumbar vertebrae, there were no significant differences between the physically active group and physically inactive group （P = 0.986 ; P = 0.579 ; P = 0.967 ; P = 0.942 ; P = 0.520 respectively）. BMC L1 and BMC L4 of the women in different groups were different （ F = 4. 172, P = 0. 017 ; F = 3. 690, P = 0.027 respectively）, of which, BMC L1 of the women in the physically inactive group was lower than that in the physically vigorously active group （P = 0.006）, and BMC L4 of the women in this group was significantly lower than both that in the physically active group and physically vigorously active group （P =0. 017, 0. 009, respectively）. Except the third lumbar vertebra （ F =2. 844, P =0.060）, in bone areas of Lm, L2 and L4 vertebrae there were differences between different groups （ F = 6.478,P = 0. 002 ; F = 5. 370,P = 0.005 ; F = 6. 197, P = 0.002, respectively） ： bone areas of L1 , L2 and L4 of those women in the physically active group were higher than both that in the other two groups （P = 0. 001,0.005 ;P = 0. 028,0.002;P = 0. 028 ,0. 001 respectively）. Conclusion We concluded that daily habitual physical activity level of postmenopausal women is related with their bone mass.
