目的了解中国6城市教师肥胖相关的知识、态度和行为,为开展儿童肥胖干预提供依据。方法采用多阶段随机整群抽样方法,从北京、哈尔滨、济南、上海、广州、重庆6座城市38所小学中抽取843名教师,进行肥胖相关知识、态度和行为的问卷调查。结果 16个肥胖相关知识题中,教师对12个问题的知晓率在95%以上,但对“中国居民平衡膳食宝塔”的知晓率仅为42.4%,仍有24.4%的教师不知道“粗粮比细粮营养更全面”。教师对于培养儿童健康生活方式的态度较好,但对“应该少看电视”、“尽量少吃西式快餐”等持正确态度的比例较低。坚持每周参加运动的教师比例为40.9%。有26.6%的教师曾经用不吃主食的方法控制体重。教师们最希望通过专家指导(63.7%)获得肥胖相关知识。结论 6城市教师对肥胖相关知识掌握较好,但对某些问题缺乏正确态度,存在某些不健康行为。 Objective To understand the obesity-related knowledge, attitudes and behaviors of teachers in 6 cities in China and provide the basis for the intervention of obesity in children. Methods A total of 843 teachers from 38 primary schools in Beijing, Harbin, Jinan, Shanghai, Guangzhou and Chongqing were enrolled in this study. A questionnaire survey was conducted on obesity-related knowledge, attitudes and behaviors using a multistage randomized cluster sampling method. Results Among 16 obesity-related knowledge questions, the awareness rate of teachers over 12 questions was above 95%, but only 42.4% of them were aware of the “Chinese dietary balance pagoda,” and 24.4% of teachers still did not know “Coarse grains more nutritious than fine grain ”. Teachers have a good attitude toward cultivating children’s healthy lifestyles, but have a lower percentage of correct attitudes such as “should watch less TV” and “try to eat less Western fast food”. The percentage of teachers insisting on participating in sports weekly is 40.9%. 26.6% of the teachers used to eat the staple food to control their weight. Teachers most want to get obesity-related knowledge through expert guidance (63.7%). Conclusions 6 city teachers have good knowledge of obesity, but they lack correct attitudes towards certain problems and some unhealthy behaviors.
