| 目的 了解中国男性大学生与东南亚地区男性大学生体力活动水平和骨密度的差异，并探讨体力活动水平与骨密度的相关性。方法 随机选取我校 442 名男性大学生，其中中国男性大学生 294 名，东南亚地区男性大学生 148 名，采用国际体力问卷(中文版)收集其近 1 周内体力活动情况，超声骨密度测量仪测量右跟骨骨密度，采用 spss16. 0 软件进行统计分析。结果 除中等强度体力活动水平以外，中国男性大学生的步行活动水平、高强度体力活动水平及总体力活动水平均高于东南亚
地区男性大学生(P ＜0. 05);中国男性大学生的骨密度明显高于东南亚地区男性大学生(P ＜0.05);pearson 相关分析，步行活动水平、中等强度体力活动水平均与骨密度无相关性(P ＜ 0. 05)，高强度体力活动水平与骨密度具有相关性(相关系数 r =
0. 157，P =0. 000)。结论 中国男性大学生的体力活动水平及骨密度均高于东南亚地区男性学生，可能与民族、遗传基因等有关;高强度体力活动能增加骨密度含量。 |

| Objective To investigate the difference of physical activity level and bone mineral density (BMD) between male
college students in China and in Southeast Asia，and to explore the correlation between the level of physical activity and BMD．
Methods A total of 442 male college students were randomly selected in our school，including 294 male college students from China
and 148 male college students from Southeast Asia． A questionnaire (Chinese version) was used to collect their physical activity in the
past 1 week． BMD of the right calcaneus was measured using an ultrasonic bone density measuring instrument． Data were statistically
analyzed using a SPSS 16. 0 software． Ｒesults Except the moderate intensity physical activity level，walking activity level，high
level of physical activity level，and total physical activity level of Chinese male students were higher than those of male college
students in Southeast Asia，and the difference was statistically significant (P ＜0. 05)． BMD of Chinese male college students was
significantly higher than that of male college students in Southeast Asia，and the difference was statistically significant (P ＜0. 05)．
Pearson correlation analysis showed that walking activity level and moderate intensity physical activity level were not correlated with
BMD (P ＜0. 05)． High intensity physical activity level was correlated with BMD (correlation coefficient r =0. 157，P =0. 000)．
Conclusion The level of physical activity and BMD of male college students in China are higher than those of male students in
Southeast Asia，which may be related to ethnic groups，genetic genes，and so on． High intensity physical activity can
increase BMD． |
