摘要目的 了解不同职业人群活动模式的各类身体活动特点.方法 采用整群随机抽样的方法,在北京市和浙江省选取35～60岁职业人群,采用调整后的全球体力活动问卷(GPAQ)询问调查对象在过去1年中身体活动相关信息,对各类身体活动的强度以代谢当量(Mets)赋值,进而计算各类身体活动量(Met-min)及构成.采用方差分析和秩和检验比较不同职业劳动模式人群的业余静态行为时间和各类身体活动量.结果 具有完整身体活动信息的职业人群共计3 326人,其中35～44岁1 567人(47.1％);女性1 671人(50.2％).职业活动以坐位读写为主(Ⅰ类)、上下肢参与但用力不多(Ⅱ类)、用力较多(Ⅲ类)的3类人群分别占30.79％、50.75％和18.46％.3类人群每周的业余锻炼、骑车活动量中位数均为0,并且家务动量的差异均无统计学意义.在非职业活动中,Ⅱ类人群家务活动量占总量的比例(58.87％)最高(F=31.814,P＜0.01),Ⅰ类人群业余锻炼量所占比例(12.70％)最高(F=14.587,P＜0.01),Ⅲ类人群的交通活动量所占比例(34.20％)最高(F=39.293,P＜0.01).Ⅰ类职业者平均每天业余静态行为时间(220.92 min)最长.结论 不同职业活动模式人群的各类身体活动情况存在差异,家务活动是各类职业人群非职业活动的主要内容.有必要针对不同人群特点,开展针对性深入研究和身体活动促进.

abstractsObjective To explore the profiles of physical activity domains among professionals with different occupational activity patterns.Methods A cluster random sampling method was used to recruit employed adults aged 30-60 years in Beijing as well as Zhejiang province.The information on the physical activity domains was collected with a revised Global Physical Activity Questionnaire (GPAQ).Results Of 3 326 professionals,about 30.79％,50.75％ and 18.46％ adults had "Class Ⅰ (mostly sedentary reading or writing during work time) ","Class Ⅱ (mostly working with arms or legs with little effort) ",and "Class Ⅲ (working with effort) " occupational activity patterns,respectively.The median volume of leisure time activity and bicycling were all 0 Met-min/week,and no significant difference of domestic activity volume was detected among all the three classes of professionals.Of all the non-occupational activity volume among three classes of adults,domestic activity accounted for the most proportion (58.87％) performed by adults of Class Ⅱ,traffic activity accounted for the most proportion (34.2％) by those of Class Ⅲ,and leisure time activity accounted for the most proportion (12.7％) by those of Class Ⅰ.Most time was spent in sedentary behaviors by those of Class Ⅰ after hours.Conclusions Besides the generally low level of moderate activity,the diversity of the domains of physical activity among this population was evident.It is necessary to develop appropriate technology to improve physical activity for professionals with different occupational activity patterns.
