静态职业人群身体活动现状调查

目的了解不同社会经济状况的静态职业人群的身体活动特点。方法采用整群随机抽样的方法，在北京市顺义区、海淀区和浙江省嘉兴市、桐乡市选取35—60岁以坐位读写为主要职业劳动形式的职业人群，进行有关社会经济状况和身体活动特点的问卷调查。结果共调查1031人。步行、骑车、中等强度业余锻炼、高强度业余锻炼等身体活动的总参与率为57．8％，并随文化程度和家庭人均收入的增长而增加（x2=25．699，P〈0．01；x2=8．768，P〈0．05）。48．0％的调查对象每周中、高强度身体活动合计量达到或超过了450～750（MET—min／w）的建议水平。不同年龄、不同文化程度者的身体活动达标情况的差异有统计学意义（x2=17．647，P〈0．01；x2=29．967，P〈0．01），不同家庭人均收入水平者的身体活动达标情况的差异无统计学意义（x2=12．784，P〉0．05）。结论中等强度及以上身体活动的总参与率受文化程度和家庭人均收入的影响，身体活动达标情况与年龄、文化程度有关。

Significant difference of standard meeting percentages was found among different age （x2 = 17. 647, P 〈 0. 01 ） and education groups （ X2 = 29. 967, P 〈 0. 01 ）, while there was no difference found a- mong different household income groups （ X2 = 12. 784, P 〉 0.05 ）.
