目的了解吉林省辽源市小学生龋齿患病情况及影响因素。方法通过分层整群随机抽样方法对吉林省辽源市2230名4~6年级小学生进行问卷调查及口腔检查,了解小学生龋齿患病情况;采用多因素logistic回归分析小学生龋齿发生的主要影响因素。结果回收有效问卷2071份,有效率92.9%。共有1413名小学生患龋齿,患龋率为68.2%。多因素logistic分析结果显示,居住城区(OR=4.511,95%CI=3.564~5.711)、低年级(OR_(4年级)=1.916,95%CI=1.496~2.455;OR_(5年级)=3.446,95%CI=2.653~4.478)、超重与肥胖(OR=1.757,95%CI=1.434~2.154)、不知道使用含氟牙膏情况(OR=1.324,95%CI=1.004~1.746)为辽源市小学生患龋齿的主要影响因素。结论吉林省辽源市小学生患龋率较高,应引起学生家长、学校及相关部门的高度重视,针对其主要影响因素制定有效的干预策略,以降低该市小学生龋齿患病率。

Objective To examine the prevalence of dental caries and its influencing factors among primary school students in Liaoyuan city of Jilin province.Methods An onsite self-administered questionnaire survey and oral examination were conducted among 2230 pupils of grade 4–6 recruited with stratified random cluster sampling from 8 primary schools in 4 districts/counties of Liaoyuan city,Jilin province during 2021.Multivariate logistic regression analysis was adopted to explore main influencing factors of dental caries for the pupils.Results Of the 2071 participants(92.9%of all pupils recruited)with complete information,1413(68.2%)were diagnosed with dental caries.The results of multivariate logistic analysis results showed that living in urban area(odds ratio[OR]=4.511,95%confidence interval[95%CI]:3.564–5.711),studying in the lower grade compared to in the grade 6(ORgrade 4=1.916,95%CI:1.496–2.455;ORgrade 5=3.446,95%CI:2.653–4.478),with overweight or obesity(OR=1.757,95%CI:1.434–2.154),not using fluoride toothpaste(OR=1.324,95%CI:1.004–1.746)were significant influencing factors of dental caries among the pupils.Conclusion The prevalence of dental caries is high among primary students in Liaoyuan city of Jilin province,suggesting that to control the prevalence,comprehensive intervention strategies should be developed for main influencing factors of dental caries among the pupils.
