摘　　要：目的了解不同体重水平职业人群业余时间身体活动认知、态度和活动(KAP)的现况。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岁职业人群,询问身体活动有关的知识、态度,并利用调整后的全球体力活动问卷(GPAQ)询问其业余时间中等强度及以上身体活动的频率和持续时间,并测量身高和体重。以代谢当量(METs)描述活动强度并计算每周活动量(MET-min/周)。结果 3297名35～60岁样本人群中,180人(5.5%)知道"每天应该活动6千步或1万步",且3249人(98.5%)认为"经常活动对促进健康重要",不同体重水平人群没有显著性差异。正常体重者业余时间中等强度身体活动的参与率(45.7%)显著低于超重(54.4%)和肥胖者(56.6%),差异有统计学意义(P<0.05)。1304人(42.6%)达到或超过了450～750MET-min/周的最低建议标准。业余时间不参加中等强度身体活动、未达标(<450MET-min/周)、达标(450～750MET-min/周)人群中肥胖者所占的比例(16.5%,17.7%,17.4%)均显著低于活动超标(≥750MET-min/周)人群中的比例(21.9%),差异有统计学意义(P<0.05)。结论不同体重水平的样本人群身体活动有关知识知晓率普遍较低,业余时间中等强度活动相对较少,有必要加强身体活动促进和健康教育。Objective To understand the characteristics of knowledge, attitude and practice （KAP） related to physical activity in leisure time among employed adults with different body weight. Methods A cluster random sampling method was used to recruit employed adults aged 35-60 years old in Shunyi and Haidian districts in Beijing as well as in Jiaxing and Tongxiang in Zhejiang Province. After measuring their body height and weight, the information of KAP related to physical activity were collected. Moderate and high intensity activity during their leisure time was inquired by modified global physical activity questionnaire （GPAQ）. METs were used to illustrate activity intensity and activity volume per week （MET-min/w） was computed. Results Of 3 297 adults enrolled, 180 persons （5.5%） were aware of ＂6 000 or 10 000 steps per day＂, while 3 249 （98.5%） believed ＂regular activities are good for health＂. The percentage of those with normal body weight who engaged in afterhours moderate or high intensity activity was significantly lower than that of those with over-weight （45.7% vs. 54.4%） or with obese （56.6%）. A total of i 304 adults （42.6%） met or exceeded the recommended minimum activity criteria of 450-750 MET-mi/w. Among the subjects with obesity, the proportion of those without moderate or high intensity activity in leisure time, activity volume per week 〈450 MET-min/w, and activity volume per week between 450-750 MET-min/w was 16.5%, 17.7% and 17.4%, respectively; which all significantly lower than that （21.9%） in those with activity volume per week 〉750 MET-min/w （P〈0.05）. Conclusion The awareness of KAP related to afterhours moderate or high intensity physical activity still remains some gaps among the population with different level of body weight. It is necessary to enhance health education and promote physical activity.
