目的了解西安市7~10岁儿童口腔健康相关知识和行为情况,为开展儿童口腔健康教育提供参考。方法多阶段随机整群抽取西安市1 180名7~10岁儿童,采用集体填写学龄儿童口腔健康知识和行为调查问卷的方法进行横断面调查。结果龋齿病因及日常防龋方法的知晓率均不足85%,正确刷牙率低于70%。口腔健康知识知晓率和正确刷牙率,城市优于农村(χ~2值分别为46.227,108.645,P值均<0.01),女孩好于男孩(Fisher确切概率法,P值均<0.05),较高年级组的知晓率也较高(χ~2=23.056,P<0.01)。结论应该加强农村地区口腔健康教育工作,充分发挥大众媒体以及学校和社区的作用,以丰富多样的形式、通俗易懂的内容对儿童及家长同时进行宣教。
Objective To understand the oral health related knowledge and behavior of children aged 7 ~ 10 in Xi’an and to provide reference for the oral health education in children. Methods A total of 1,180 children aged 7-10 years old in Xi’an were collected by multi-stage random cluster analysis. Cross-sectional surveys were conducted by using collective oral health knowledge and behavior questionnaire. Results The awareness rate of dental caries and daily caries prevention methods were less than 85%, and the correct brushing rate was less than 70%. Oral health awareness and correct brushing rate were higher in urban areas than in rural areas (χ ~ 2 values 46.227 and 108.645, P <0.01 respectively), girls better than boys (Fisher exact test, P <0.05) High-grade group awareness is also higher (χ ~ 2 = 23.056, P <0.01). Conclusion Oral health education in rural areas should be strengthened and the role of the mass media, schools and communities should be brought into full play. Children and parents should be simultaneously educated in a variety of forms and with easy-to-understand contents.
