目的了解广州市荔湾区低龄儿童龋病(ECC)的流行情况及其影响因素,为儿童ECC防治提出对策。方法采用整群抽样的方法,选取广州市荔湾区3所幼儿园783名1~6岁儿童为研究对象。对儿童进行口腔健康检查,对家长进行问卷调查。结果 783名儿童患龋率为39.59%(310/783),其中男童患病率为40.62%,女童为38.58%。310名ECC儿童共检出龋齿1 454个,龋失补牙数(dmft)为4.69,其中男童为4.56,女童为4.83。多因素逐步Logistic回归分析显示,户籍分布、父母监督孩子刷牙、每天饮用碳酸饮料次数、父亲文化程度、喂养方式、母亲文化程度、年龄组、睡前刷牙、饭后漱口、开始刷牙时间等10个因素均入选方程,均为ECC发生的独立影响因素(P值均<0.01)。结论儿童ECC的发生率较高;ECC发生与生活环境、父母对儿童口腔健康重视程度、饮食及饮食习惯、生活方式、口腔卫生习惯等因素关系密切。
Objective To understand the prevalence and influencing factors of dental caries (ECC) in young children in Liwan District of Guangzhou City and to provide countermeasures for the prevention and treatment of ECC in children. Methods A cluster sampling method was used to select 783 children aged 1 ~ 6 years from 3 kindergartens in Liwan District of Guangzhou City as the research object. Oral health checkups for children, and questionnaire surveys of parents. Results The caries prevalence of 783 children was 39.59% (310/783), of which 40.62% were for boys and 38.58% for girls. A total of 1 454 dental caries were detected in 310 ECC children. The number of dental caries lost (dmft) was 4.69, of which 4.56 were for boys and 4.83 for girls. Logistic regression analysis showed that the distribution of household registration, parental supervision of children brushing their teeth, drinking carbonated drinks daily, father’s education, feeding methods, mother’s education level, age group, brushing before going to bed, mouthwash after meals, starting brushing time 10 All the factors were included in the equation, which were all independent factors of ECC (P <0.01). Conclusions The incidence of ECC in children is high. The occurrence of ECC is closely related to the living environment, the importance of parents to children’s oral health, diet and eating habits, life style and oral health habits.
