广西3～5岁儿童患龋情况与口腔健康行为的相关性研究

Relationship between Caries Status and Oral Health Behaviors among Children Aged 3-5 Years in Guangxi,China

目的:了解广西3~5岁儿童患龋情况,分析口腔健康行为和患龋率之间的关系。方法:采用多阶段分层等容量随机抽样方法,抽取广西3~5岁幼儿园儿童1949名,对其进行口腔健康检查,家长则接受面对面问卷调查,并通过Logistic回归模型探索口腔健康行为和患龋率之间的关系。结果:广西3~5岁儿童患龋率为72.3%,龋均为4.52,城市患龋率和龋均高于农村(P<0.05)。调整年龄、性别、家长学历、居住地后,甜点心、甜饮料摄入频率高及睡前吃甜食的儿童患龋风险更高(P<0.05)。调整口腔健康行为因素后,城市儿童患龋风险仍然高于农村(P<0.05)。结论:广西3~5岁儿童患龋情况严重,甜点心及甜饮料摄入频率、睡前吃甜食频率与儿童患龋有关,口腔健康行为因素不能解释城乡儿童间的患龋差异。

Objective:To investigate the caries status and explore the relationship between oral health behaviors and the prevalence of caries in children aged 3~5 years in Guangxi,China.Methods:A total of 1949 children aged 3-5 years were selected from kindergartens in Guangxi by using multi-stage stratified equal-volume random sampling method for oral health examination,and face-to--face questionnaire survey was conducted among parents.Logistic regression was used to explore the relationship between oral health behaviors and caries.Results:The prevalence of caries in children aged 3-5 years in Guangxi was 72.3%,and the mean dmft was 4.52.After adjusting for age,gender,parental education and place of residence,higher frequency of sweet snacks,sweet drinks and taking sweets before going to bed were significantly associated with higher risk of caries.After adjusting for oral health behaviors,urban children still have a higher probability of caries than rural.Conclusion:Children aged 3-5 years in Guangxi have serious caries.The frequency of sweet snacks,sweet drink intake,and the frequency of eating sweets before going to bed are related to children's caries.Oral health behaviors cannot fully explain the differences in caries between urban and rural children.
