成都市学龄前儿童龋病与出生状况的调查分析

目的:了解学龄前儿童龋病与其出生状况的关系,筛选患龋的高危人群。方法:对四川省成都市五城区3~6 岁儿童2500名进行患龋情况调查,随机选取龋敏感儿童和无龋对照儿童各260名,按年龄、性别配对,对出生状况、喂养方式、饮食习惯等29个可能引起儿童乳牙龋的指标变量进行问卷调查,获得200对有效样本。对样本进行Lo- gistic回归及V2检验分析。结果:新生儿出生状况对学龄前儿童的乳牙龋有影响(P<0105),出生时为早产儿的学龄前儿童患龋状况较出生时为足月产的学龄前儿童患龋严重(P<0105),足月难产与足月顺产的新生儿到学龄前其患龋无明显差异(P>0105)。结论:为更好地预防儿童龋病,应将胎龄不足的早产儿作为龋病预防的重点人群。

A Study on the Relationship between Deciduous Tooth Caries in Pre-school Children and Their Neonatal Conditions

OBJECTIVE: This study was designed to examine whether the neonatal conditIon might be related to the caries of deciduous teeth in pre-school children. METHODS: 1000 children from 3 years old to 6 years old in Chengdu were surveyed, and 260 children with dmft > or = 6 and 260 caries-free children were chosen. Data was collected by 200 pairs of useful questionnaire from their parents and analyzed by using logistic regression analysis and chi 2 test. RESULTS: The neonatal condition was closely related with incidence rates of deciduous caries in pre-school children (P < 0.05). The incidence rate of children with premature delivery was higher than that with full-term normal delivery (P < 0.05). No significant difference was showed in children with full-term normal delivery and children with dystrophy (P < 0.05). CONCLUSION: There should be emphasis on the children with premature delivery in caries preventive cares.
