目的了解东北地区12岁儿童口腔健康知识、行为现状,为东北地区口腔卫生保健工作提供信息支持。方法按照第3次全国口腔健康流行病学抽样调查方案,对东北9个城市、9个农村地区部分12岁学生进行集体自答式问卷调查,并采用SPSS14.0软件包对数据进行分析。结果 12岁学生每天刷牙率为74.7%,城市高于农村(P<0.01),女生高于男生(P<0.01)。每天进食含糖食品的比例为62.1%,城乡之间、性别之间差异均无统计学意义(P值均>0.05)。口腔卫生知识及含氟牙膏知晓率偏低;获取口腔卫生保健知识的途径主要通过媒体;过去12个月口腔科就诊率为54.2%,农村(60.8%)高于城市(47.2%)(P<0.01),就诊的主要原因是急慢性牙痛和其他口腔问题绝大部分12岁学生对自己的牙齿、牙龈和口腔卫生状况表示满意。大部分学生认为定期口腔检查非常必要,但实际接收定期检查的学生只占1/3。结论学生口腔保健的基本知识尚不普及。应加强口腔保健知识特别是有效刷牙的宣传教育,促进儿童尤其是农村儿童建立口腔健康行为。
Objective To understand the oral health knowledge and behaviors of 12-year-old children in Northeast China and to provide information support for the oral health care in northeast China. Methods According to the 3rd National Oral Health Epidemiology Sampling Survey, a questionnaire survey was conducted among 9 cities in Northeast China and some 12-year-olds in 9 rural areas. SPSS14.0 software package was used to analyze the data. Results The average brushing rate of 12-year-old students was 74.7%, higher in rural than in rural areas (P <0.01), and higher in girls than in boys (P <0.01). The proportion of eating sugary foods per day was 62.1%. There was no significant difference between urban and rural areas (P all> 0.05). Oral hygiene knowledge and low awareness of fluoride toothpaste; access to oral health care knowledge mainly through the media; in the past 12 months, the stomatology clinic rate was 54.2%, rural areas (60.8%) higher than the city (47.2%) (P < 0.01). The main reason for the visit was acute and chronic toothache and other oral problems. Most 12-year-old students expressed satisfaction with their dental, gingival and oral hygiene. Most students think regular oral examinations are necessary, but only 1/3 actually receive regular exams. Conclusions Students’ basic knowledge of oral health is not yet universal. Publicity and education on oral health knowledge, especially effective brushing should be strengthened so as to promote the oral health behaviors of children, especially rural children.
