Pre-school dental caries is a significant public health problem and may be associated with the growth and nutritional status of children. This study aimed to investigate the association between body mass index (BMI) and early childhood caries (ECC) among pre-school children.
This population-based retrospective study involves all 5-year-old children who resided in northern New Zealand and received school entry dental examinations between 1 January 2014 and 31 December 2015. ECC status was determined with the decayed missing filled teeth (dmft) score obtained from a routinely collected regional dental data set. Objectively measured BMI information was obtained from the 'Before School Check' (B4SC) Programme. Logistic regression analyses were used to assess the association between BMI and the occurrence of ECC (dmft score ≥ 1). Ethnic subgroup analyses were also conducted.
Of the 27 333 children involved in this analysis, 11 173 (40.9%) had ECC with a mean dmft score of 1.85, and 3948 (14.4%) were overweight and 2964 (10.8%) were obese at school entry. The prevalence of ECC was higher in overweight and obese children but in subgroup analyses by ethnicity, this positive association was observed in European children only (adjusted odds ratio for overweight children compared to normal weight children: 1.16; 95% CI: 1.02, 1.32 and adjusted odds ratio for obese children: 1.20; 95% CI: 1.00, 1.45).
ECC is highly prevalent in New Zealand children and associated with higher BMI in children of European ethnicity.
学前龋齿是一个重大的公共卫生问题，可能与儿童的生长和营养状况有关。本研究旨在调查儿童肥胖指数（BMI）与学龄前儿童早期儿童龋（ECC）之间的关系。
这是一项基于人群的回顾性研究，涉及所有居住在新西兰北部并在 2014 年 1 月 1 日至 2015 年 12 月 31 日期间接受学校入学牙科检查的 5 岁儿童。ECC 状况通过从常规收集的区域牙科数据集获得的龋齿、缺失和补牙（dmft）评分来确定。客观测量的 BMI 信息从“入学前检查”（B4SC）计划中获得。使用逻辑回归分析评估 BMI 与 ECC（dmft 评分≥1）发生之间的关系。还进行了种族亚组分析。
在参与这项分析的 27333 名儿童中，有 11173 名（40.9%）患有 ECC，平均 dmft 评分为 1.85，3948 名（14.4%）超重，2964 名（10.8%）肥胖。超重和肥胖儿童的 ECC 患病率较高，但在按种族进行的亚组分析中，这种正相关仅在欧洲儿童中观察到（与正常体重儿童相比，超重儿童的调整优势比：1.16；95%CI：1.02，1.32；肥胖儿童的调整优势比：1.20；95%CI：1.00，1.45）。
新西兰儿童的 ECC 患病率很高，与欧洲裔儿童的 BMI 较高有关。
