This cross-sectional study aimed to determine the association between dental caries and weight status, and between dental caries and physical activity in Brazilian schoolchildren aged 8 to 12 years. A multi-stage sample of children enrolled in 20 private and public schools in 2010 in Pelotas, Southern Brazil, were invited to participate in the study. Socioeconomic data were collected from parents, and data regarding children characteristics were collected from children using a questionnaire and anthropometric measures. The Body Mass Index was obtained, and children were classified as overweight/obese considering age and sex. Dental examinations were performed to assess the presence of gingival inflammation, dental caries prevalence (DMFT≥1) and dental caries experience (mean DMFT). Multivariate Poisson Regression was used to assess factors associated with dental caries prevalence and experience. A total of 1,210 children were included in the study. Dental caries prevalence was 32.4% (95% CI 29.7-35.2), while the mean DMFT was 0.64 (± SD 1.00). Children who practiced less than 300 minutes per week of physical activity and overweigh/obese children had lower prevalence of dental caries, while children with obesity or overweight presented lower dental caries experience. Obesity/overweight and physical activity level presented an inverse relationship with dental caries. Longitudinal studies investigating the complexity of this relationship are required.
这项横断面研究旨在确定巴西8至12岁学童龋齿与体重状况之间以及龋齿与身体活动之间的关联。2010年，从巴西南部佩洛塔斯的20所私立和公立学校中抽取的多阶段样本儿童被邀请参与该研究。从家长处收集社会经济数据，并使用问卷和人体测量方法从儿童处收集有关儿童特征的数据。计算体重指数，并根据年龄和性别将儿童分类为超重/肥胖。进行牙科检查以评估牙龈炎症的存在、龋齿患病率（DMFT≥1）和龋齿经历（平均DMFT）。采用多变量泊松回归分析评估与龋齿患病率和经历相关的因素。共有1210名儿童纳入研究。龋齿患病率为32.4%（95%CI 29.7 - 35.2），而平均DMFT为0.64（±标准差1.00）。每周体育活动少于300分钟的儿童和超重/肥胖儿童龋齿患病率较低，而肥胖或超重儿童龋齿经历较少。肥胖/超重与身体活动水平与龋齿呈负相关。需要进行纵向研究来探究这种关系的复杂性。
