广西5岁儿童乳牙龋病相关因素分析

Deciduous teeth caries status and impact factors in a 5 year old Guangxi cohort

目的:调查广西5岁儿童乳牙患龋情况及相关影响因素,为儿童龋病预防提供资料。方法:采用多阶段、分层、等容量、随机抽样的方法抽取广西420名5岁儿童进行乳牙龋病检查,同时对其家长进行现场问卷调查。对调查结果采用卡方检验分析和多因素非条件Logistic回归分析。结果:乳牙患龋率和龋均分别为80.7%、6.06,男女间差异无统计学意义(P>0.05)。单因素分析表明城乡差别、是否壮族、家长职业、学历、父母有无获得口腔健康知识途径、对含氟牙膏知晓率、是否检查孩子刷牙效果、儿童开始刷牙年龄、儿童喝奶习惯等相关因素都对乳牙患龋有明显影响。多因素Logistic回归分析表明壮族儿童、家长没有听说过含氟牙膏、家长不检查孩子刷牙效果是儿童乳牙患龋的危险因素。结论:广西儿童口腔健康工作的重点对象是农村、壮族儿童,通过提高儿童家长应对口腔健康知识的知晓率,主动采取利于口腔健康的行为,以帮助儿童建立健康的口腔行为。

AIM： To investigate the status of deciduous caries in a population 5-year olds in Guangxi and the possible relative influencing factors, thus to provide scientific basis for the establishment of oral health care policies in Guangxi. METHODS： An Equal-sized stratified multi-stage randomly sampling design was applied to obtain a rep- resentative sample group consisted of Guangxi residents aged 5 years, with a gender ratio of 1 ： 1. The caries on the crown of deciduous teeth was assessed ; thereafter the data including their oral health habits, diet condition, and family -related factors etc. were obtained through questionnaires from children＇ s parents. RESULTS： In the group aged 5, the caries rate was 80.7%, and the mean dmft（ decayed, missed and filled teeth） was 6.06, there was no significant difference of prevalence between two sexes （ P 〉 0.05 ）. In a multivariate logistic regression model, three factors inclu- ding Zhuang nationality, the knowledge of fluoride toothpaste and checking the effect of children＇ s teeth brushing were proved to be relevant to deciduous teeth caries, although in single variable analysis the data showed that except these key variables more factors such as the frequency of intake of dairy products and the start age of bushing teeth also ex- hibited obvious impact on the status of deciduous caries. CONCLUSION： More efforts are in crucial need to help the rural and Zhuang children with their oral health behavior through promoting their parents＇ awareness, attitude and be- havior of oral health.
