METHODS: A cross-sectional study was carried out in the Northeast of Brazil. The sample was comprised of 793 schoolchildren randomly selected from public and private schools. Calibrated examiners (Kappa >0.80) performed the clinical examination of dental caries using the International Caries Detection and Assessment System and applied the Revised Children\'s Manifest Anxiety Scale and the Sleep Disturbance Scale for Children questionnaires. The anthropometric variables evaluated were weight and height. Negative binomial regressions (α ≤ 0.05) were performed. A Directed Acyclic Graph was prepared using DAGitty software (version 3.0), to select the co-variables for the statistical fits.
RESULTS: The prevalence of tooth decay was 52.8%. The mean number of tooth surfaces with cavitated caries was 2.2(2.8), 58.9% of the schoolchildren had some type of sleep disorder, while 20.2% were anxious and 29.1% were obese. Sleep disturbance (RR = 1.38; 95% CI: 1.05-1.83), general anxiety (RR = 1.71; 95% CI: 1.32-2.21), obesity (RR = 1.48; 95% CI: 1.17-1.86) were associated with dental caries in the final model.
CONCLUSIONS: The presence of carious lesions was higher in children with sleep disorders, anxiety, obesity, and those who experienced dry mouth.
方法:在巴西东北部进行了一项横断面研究。样本由从公立和私立学校随机选择的793名学童组成。校准检查者(Kappa>0.80)使用国际龋齿检测和评估系统进行龋齿的临床检查,并应用修订的儿童表现焦虑量表和儿童睡眠障碍量表问卷。评估的人体测量变量是体重和身高。进行负二项回归(α≤0.05)。使用DAGitty软件(3.0版)制备了一个有向无环图,选择统计拟合的共变量。
结果:蛀牙的患病率为52.8%。有空化龋齿的牙齿表面的平均数量为2.2(2.8),58.9%的学童有某种类型的睡眠障碍,20.2%的人焦虑,29.1%的人肥胖。睡眠障碍(RR=1.38;95%CI:1.05-1.83),一般焦虑(RR=1.71;95%CI:1.32-2.21),在最终模型中,肥胖(RR=1.48;95%CI:1.17-1.86)与龋齿相关.
结论:睡眠障碍儿童龋齿病变的发生率更高,焦虑,肥胖,那些经历过口干的人。
