Early childhood caries (ECC) and childhood obesity are among the most prevalent health conditions affecting children. ECC is associated with obesity through the common risk factor of sugar consumption. The present study aimed to assess the association between ECC and obesity in preschool children.
A cross-sectional study was conducted among 1250 preschool children (698 girls, 552 boys; mean age: 4.3 [1.1] years). The children's body mass index was determined (BMI: weight/height in kg/m2). The World Health Organization criteria were used for the diagnosis of caries. Multivariable logistic regression was used to analyse the relationship between ECC prevalence and childhood obesity.
ECC was detected in 929 (74.3%) children. The mean dmft and dmfs was 5.91 (1.13) and 8.92 (2.07), respectively. The multiple regression model showed a statistically significant association between ECC prevalence and obesity with an adjusted odds ratio (OR) of 2.59 (95% CI: 1.88 - 3.57; P = 0.001). The logistic regression model showed that in children with a monthly family income > $2666, sugar consumption, preterm low birth-weight/full-term low birth-weight (PTLBW/FTLBW), and toothbrushing frequency ≤ 1 time/day were statistically significantly associated with ECC prevalence.
ECC was positively associated with obesity.
儿童龋病（ECC）和儿童肥胖症是影响儿童健康的最常见疾病之一。ECC 通过糖消耗这一共同危险因素与肥胖相关。本研究旨在评估学龄前儿童 ECC 与肥胖之间的关系。
本研究为横断面研究，共纳入 1250 名学龄前儿童（女孩 698 名，男孩 552 名；平均年龄：4.3[1.1]岁）。儿童的体重指数（BMI：kg/m2）。采用世界卫生组织（WHO）标准诊断龋病。采用多变量逻辑回归分析 ECC 患病率与儿童肥胖的关系。
929 名（74.3%）儿童检出 ECC。dmft 和 dmfs 的平均值分别为 5.91（1.13）和 8.92（2.07）。多因素回归模型显示 ECC 患病率与肥胖之间存在统计学显著关联，调整后的优势比（OR）为 2.59（95%CI：1.88-3.57；P=0.001）。Logistic 回归模型显示，在月家庭收入＞$2666 的儿童中，糖消耗、早产低出生体重/足月低出生体重（PTLBW/FTLBW）和每日刷牙次数≤1 次与 ECC 患病率有统计学显著关联。
ECC 与肥胖呈正相关。
