北京市海淀区3岁儿童婴幼儿龋患病率调查及相关因素分析

Epidemiological investigation of early childhood caries and the correlative factors,analysis for 3 years old children in the Haidian district in Beijing

【目的】了解北京市海淀区3岁儿童婴幼儿龋(early childhood caries,Ecc)患病率及其影响因素,为探索幼儿园集体儿童龋病综合预防模式提供依据。【方法】随机抽取海淀区12所幼儿园588名3岁儿童进行患龋状况调查,并对家长进行问卷调查统,统计分析Ecc发病情况与影响因素间的关系。【结果】本研究3岁儿童Ecc患病率为47.6%,龋均(dft)为2.20,dft>3的儿童占样本量的26%,其龋齿数占样本量龋齿总数的76%;Logistic回归分析结果显示,不良的喂养方式、口腔中唾液的变链细菌水平及母乳喂养时间与Ecc的发生率有相关性。【结论】北京市海淀区刚入园3岁儿童Ecc患病率较高,治疗率低,绝大多数的龋齿集中发生在少部分人身上,提示对龋高危儿童应进行重点监控,及早进行筛查,做好防控工作。

The prevalence of early childhood caries was 47.6 %. The mean dft score was 2.20. The children with dft value greater than 3 occupy 26% of the entire examples whereas the number of their dft was 76% of the total caries. Logistic regression analysis showed that the feeding habits, the level of saliva mutans streptococci and the duration of feeding were significant. [Conclusions] 3 years old children who have just entered kindergarten have a high rate of early childhood caries and low rate of treatment. A few children have a higher risk of early childhood caries and more attention should be need to them, check for them as soon as possible, meanwhile do a better job in prevention.
