More than one-quarter of New Zealand children are overweight or obese. Research on the causes of obesity has found associations with high consumption of sweetened foods and beverages, which have also been shown to be risk factors for dental caries, but studies investigating a possible association between dental caries and obesity have had conflicting findings.
The aim of this study was to determine whether deciduous dental caries experience was associated with BMI among paediatric dental clinic attenders.
This was a cross-sectional study of clinical records of 200 children aged eight and under (70% European) treated in the University of Otago undergraduate paediatric dentistry clinic between 2004 and 2006. Height and weight were measured and used to calculate BMI. Deciduous dental caries experience was recorded.
The overall mean BMI was 16.0 (SD = 2.0). Pacific Island children had a higher mean BMI (at 17.0) than NZ European, Maori, and Asian/Other children (15.7, 16.8, and 15.9 respectively; P < 0.05). The dmft ranged from 0 to 15, with a mean of 6.1 (SD = 3.8); 24% had dmft <3, and 38% had dmft >8. No significant association was found between the BMI and caries experience (P-value = 0.932).
There was no association between BMI and dental caries experience in this convenient sample.
超过四分之一的新西兰儿童超重或肥胖。肥胖原因的研究发现，与高糖食品和饮料的消费有关，而这些食品和饮料也被认为是龋齿的危险因素，但调查龋齿和肥胖之间可能存在关联的研究得出了相互矛盾的结果。
本研究旨在确定乳牙龋齿经历是否与儿科牙科诊所就诊者的 BMI 相关。
这是一项对 200 名 8 岁以下（70%为欧洲人）儿童的临床记录进行的横断面研究，这些儿童于 2004 年至 2006 年在奥塔哥大学本科儿科牙科诊所接受治疗。测量身高和体重，并用于计算 BMI。记录乳牙龋齿经历。
总体平均 BMI 为 16.0（SD = 2.0）。太平洋岛屿儿童的 BMI 平均值（17.0）高于新西兰欧洲人、毛利人和亚洲/其他儿童（分别为 15.7、16.8 和 15.9；P<0.05）。dmft 范围从 0 到 15，平均值为 6.1（SD = 3.8）；24%的儿童 dmft<3，38%的儿童 dmft>8。BMI 与龋齿经历之间没有显著关联（P 值=0.932）。
在这个方便的样本中，BMI 与龋齿经历之间没有关联。
