The aim of the present study was to evaluate the association between dental caries, childhood body mass index (BMI), and socioeconomic status in Swedish children.
The study cohort consisted of 2303 10-year-old children with data on socioeconomic status, BMI at 4, 5, 7 and 10 years of age, and caries at 6, 10 and 12 years of age. Anthropometric measures were carried out by trained nurses according to standardized routines. The occurrence of caries was registered from county records, and the children were classified into one of five socioeconomic clusters based on their census registration address.
Caries prevalence decreased with increasing socioeconomic status at all ages, whereas childhood BMI and proportion of overweight/obese children were unrelated to socioeconomic status. Obese, but not overweight, children had more caries affected teeth than non-obese, and BMI had an independent, though weak, effect on caries variation in multiple regression. Interestingly, overweight/obese 4-year-olds, who had normal body weight at 5, 7 and 10 years of age, had significantly less caries than children who had normal body weight from 4 to 10 years of age.
Overweight and caries prevalence are significantly associated in Swedish children. However, the association is weak. Nevertheless, the concept that child dental services and child welfare services can benefit from joint programs is supported.
本研究旨在评估瑞典儿童龋齿、儿童体重指数（BMI）与社会经济地位之间的关联。
研究队列由2303名10岁儿童组成，这些儿童有社会经济地位数据，以及4岁、5岁、7岁和10岁时的BMI数据，还有6岁、10岁和12岁时的龋齿数据。人体测量由经过培训的护士按照标准化程序进行。龋齿的发生情况从县记录中登记，并且根据儿童的人口普查登记地址将他们分为五个社会经济类别之一。
在所有年龄段，龋齿患病率均随着社会经济地位的提高而降低，而儿童BMI以及超重/肥胖儿童的比例与社会经济地位无关。肥胖儿童（而非超重儿童）比非肥胖儿童有更多患龋齿的牙齿，并且在多元回归分析中，BMI对龋齿变化有独立的（尽管较弱）影响。有趣的是，4岁时超重/肥胖但在5岁、7岁和10岁时体重正常的儿童，比4至10岁体重一直正常的儿童患龋齿的情况明显更少。
在瑞典儿童中，超重与龋齿患病率显著相关。然而，这种关联较弱。尽管如此，儿童牙科服务和儿童福利服务可以从联合项目中受益这一观点得到了支持。
