This study aimed to investigate the early childhood caries (ECC) prevalence among preschoolers aged 3-5 years in Xiangyun of Yunnan, China and explore the factors associated with the prevalence.
A cross-sectional survey including 3-5-year-old children was conducted in Xiangyun County, China, between September and November 2020. According to the dental examination standard of the WHO 2013 criteria, the presence of ECC was recorded. Besides the dental examination for children, their parents completed questionnaires about caries-related factors, including demographic variables, family socioeconomic status, feeding, and oral health-related habits, parental dental knowledge, and the condition of dental service utilization. SPSS Statistics 25.0 (IBM, Chicago, IL, USA) was used for data analysis. Statistical significance was set at < 0.05.
The ECC prevalence among a sample of 1,280 children aged 3-5 years consisting of 665 boys and 615 girls in this study, was 74.3%, and the mean decayed-missing-filled teeth (dmft) was 4.9 ± 5.0. There were no statistically significant differences in the ECC prevalence between the sexes and among different ethnic groups. Children with different dietary and oral hygiene habits showed no significantly different prevalence of ECC. Logistic regression analysis showed that the most significantly associated factors were older age, lower family income, and worse parental perception of children's oral health status.
The ECC prevalence among 3-5-year-old preschool children in Xiangyun was higher than the average national ECC prevalence in China. This study implies that more attention should be given to children's caries prevention from early childhood; oral health education and promotion should be intensified to reduce the ECC prevalence and improve the oral health status of children in Xiangyun.
本研究旨在调查中国云南祥云县 3-5 岁学龄前儿童的幼儿龋（ECC）患病率，并探讨与患病率相关的因素。
本研究采用横断面调查方法，于 2020 年 9 月至 11 月在云南省祥云县对 3-5 岁儿童进行调查。根据世界卫生组织 2013 年标准的口腔检查标准，记录 ECC 的存在情况。除了对儿童进行口腔检查外，其家长还完成了与龋病相关因素的问卷调查，包括人口统计学变量、家庭社会经济状况、喂养、口腔健康相关习惯、父母口腔健康知识和口腔服务利用情况。采用 SPSS Statistics 25.0（IBM，芝加哥，IL，美国）进行数据分析。统计显著性设为<0.05。
本研究共纳入 1280 名 3-5 岁儿童，其中男童 665 名，女童 615 名，ECC 患病率为 74.3%，平均患龋失补牙数（dmft）为 4.9±5.0。性别和不同民族之间 ECC 患病率无统计学差异。不同饮食和口腔卫生习惯的儿童 ECC 患病率无显著差异。Logistic 回归分析显示，年龄较大、家庭收入较低和父母对儿童口腔健康状况的认知较差是最显著的相关因素。
祥云县 3-5 岁学龄前儿童 ECC 患病率高于中国全国平均 ECC 患病率。本研究表明，应更加关注儿童龋病预防，加强口腔健康教育和促进，以降低祥云县儿童 ECC 患病率，改善儿童口腔健康状况。
