川渝地区学龄前儿童乳牙患龋状况与全身营养状况的关系

Relationship between caries status of primary tooth and nutritional condition of preschool children in area of Sichuan and Chongqing

目的探索川渝地区学龄前儿童乳牙患龋状况与儿童全身营养状况的关系。方法随机抽取川渝4市9所幼儿园的学龄前儿童713名,进行全口乳牙患龋情况调查和身高、体质量测量,计算其BMI指数,并由此将纳入对象分为低BMI、中BMI和高BMI组,分析学龄前儿童BMI指数与其乳牙患龋率和龋均的相关性。结果不同BMI分组的学龄前儿童患龋率和龋均无统计学意义(P>0.05);不同dft分组的学龄前儿童其BMI指数无统计学意义(P>0.05)。结论川渝地区学龄前儿童乳牙患龋状况与全身营养状况之间未发现相关性。

Objective To explore the relationship between caries status of primary tooth and nutritional condition of preschool children in the area of Sichuan and Chongqing. Methods A total of 713 preschool children in 9 kindergartens were randomly recruited from 4 cities of the area of Sichuan and Chongqing. The examination of caries status of primary tooth and the measurements of the weight（ kg） and height（ m） were performed. The BMI was calculated and the children were divided into 3 groups（ low BMI,medium BMI and high BMI）. The correlation between BMI and the caries prevalence rates and average caries was analyzed respectively. Results There was no significant difference between the caries prevalence rate and BMI and between average caries and BMI,respectively（ P〉0. 05）. Conclusions There is no correlation between caries status of primary tooth and nutritional condition of preschool children in the area of Sichuan and Chongqing.
