Previous study revealed that the link between dental caries and obesity has been controversial. The purpose of this research is to investigate the association between dental caries and obesity among primary school children in Wannan area, China.
A cross-sectional study was designed to collect the routine health screening data for primary school children aged 5-14 years in Wannan area,China, Overweight and obesity status were determined using the International Obesity Task Force standard (IOTF) BMI cut-off points. Caries status was recorded based on WHO recommendations.
Our results revealed that the overall caries prevalence of the subjects was 44.9%, Maximum number of caries affected children belonged to underweight and normal group, followed by overweight, and the least number was obesity. These differences were statistically significant (chi-square test, P < 0.001). Children with obesity were 1.908 times (OR =1.908; CI95%=1.750, 2.079) more likely have caries than children with underweight or health weight. Overweight children were 1.547 times (OR = 1.547; CI95% = 1.479, 1.618) more likely to have caries than children with underweight or health weight. After adjusted the gender and age, a statistically significant association was also observed between body mass index categories and caries.
Obesity may have a significant effect on caries prevalence of primary school children in Wannan area, China. The importance of obesity should not only be emphasized with respect to general diseases but also with regard to carious lesions.
先前的研究表明，龋齿与肥胖之间的联系一直存在争议。本研究的目的是调查中国皖南地区小学生龋齿与肥胖之间的关联。
设计一项横断面研究，收集中国皖南地区5-14岁小学生的常规健康筛查数据。采用国际肥胖特别工作组（IOTF）的BMI切点来确定超重和肥胖状况。根据世界卫生组织的建议记录龋齿状况。
我们的结果显示，受试者的总体龋齿患病率为44.9%。受龋齿影响儿童数量最多的是体重不足和正常组，其次是超重组，最少的是肥胖组。这些差异具有统计学意义（卡方检验，P<0.001）。肥胖儿童患龋齿的可能性是体重不足或健康体重儿童的1.908倍（OR=1.908；95%CI=1.750，2.079）。超重儿童患龋齿的可能性是体重不足或健康体重儿童的1.547倍（OR=1.547；95%CI=1.479，1.618）。在调整性别和年龄后，体重指数类别与龋齿之间也观察到具有统计学意义的关联。
肥胖可能对中国皖南地区小学生的龋齿患病率有显著影响。不仅应在一般疾病方面强调肥胖的重要性，还应在龋齿病变方面予以强调。
