成都市与徐州市5岁和12岁儿童酸蚀症患病情况比较

目的了解成都市和徐州市5岁和12岁儿童酸蚀症的患病情况,为政府检测和评价口腔预防保健工作、制定口腔健康目标规划提供信息支持和科学依据。方法参照第3次全国口腔健康流行病抽样调查,采用分层整群随机抽样方法,对成都市区969名5岁儿童、1142名12岁儿童和徐州市区1219名5岁儿童、786名12岁儿童进行牙齿酸蚀症检查登记和问卷调查。采用Logistic回归分析方法,分析影响酸蚀症的有关因素。结果5岁组酸蚀症的患病率为11.56,不同性别儿童差异无统计学意义(P>0.05);成都市5岁儿童酸蚀症的患病率为12.38,徐州市为10.91,差异无统计学意义(P>0.05)。12岁儿童酸蚀症的患病率为23.65,不同性别儿童差异无统计学意义(P>0.05);成都市12岁儿童酸蚀症的患病率为24.69,徐州市为22.14,差异无统计学意义(P>0.05)。Logistic回归分析结果显示,酸蚀症危险因素分别为酸性水果、酸奶、运动饮料、碳酸饮料、果汁,睡前喝酸性饮料或酸奶、胃食道返流性疾病、维生素C、补铁剂。结论成都市和徐州市儿童酸蚀症患病情况较为严重。应减少儿童酸性食品和饮料的摄入,加强口腔卫生教育和饮食指导,促进口腔健康。

Comparison of Tooth Erosion Prevalence in 5-and 12-year-old Children in Chengdu and Xuzhou

Objective To know the prevalence and the distribution characteristics of tooth erosion in a representative sample of 5-year-old and 12-year-old children in Chengdu and Xuzhou,and to provide evidence for oral health care and making oral health strategies.Methods The stratified cluster random sampling methods were performed.A random sample of 969 children aged 5,1 142 children age 12 were chosen in Chengdu and 1 219 children aged 5,786 children aged 12 were chosen in Xuzhou.Tooth erosion was assessed using the index employed in the survey of The Third Dental Health Survey in China.Multi-factors to tooth erosion also were investigated and analyzed with Logistic regression model in the study.Results The prevalence of tooth erosion was 11.56% in 5-year-old children group(12.38%for Chengdu,10.91% for Xuzhou) and 23.65% in 12-year-old children group(24.19%for Chengdu,22.14% for Xuzhou).There was no significant differences between male and female or two cities respectively(P>0.05).Logistic regression analysis showed that the risk factors were acidic fruits,yoghurt,sport drinks,carbonated drinks,fruit juice,gastroesophageal reflux disease,vitamin C,drinking acidic drinks before sleeping and Fe supplement.Conclusion The prevalence of tooth erosions is high in Chengdu and Xuzhou.In order to improve oral health education and improve quality of life,oral health education and dietary guidance should be strengthened to restrict children' s intake of acid foods.
