The aim of this study was to determine the association between obesity and caries by utilizing the data of a cohort of preschool children aged 4-5 years.
Data were obtained from a cohort of 1,160 children. Dental caries detection was performed according to the World Health Organization criteria. The caries index was measured as the number of decayed (d), extracted (e), and filled (f) teeth (t) (deft), or surfaces (defs). The body mass index (BMI) in units of kg/m2 was determined, and children were categorized according to age- and gender-specific criteria as normal weight (5th-85th percentile), at-risk overweight (> or = 85th-<95th percentile), and overweight (> or = 95th percentile). Odds ratios were determined for at-risk overweight and overweight children using logistic regression.
The prevalence of dental caries was 17.9 percent. A slightly higher percentage of dental caries was found in boys (19.6 percent) than in girls (16.4 percent). From the total sample, the mean BMI was 17.10 +/- 3.83. Approximately 53.7 percent of children were classified as normal weight, 14.2 percent as at-risk overweight, and 32.1 percent as overweight. At-risk overweight children were higher among girls (17.1 percent) than among boys (11.3 percent). When adjusted for covariates, the logistic regression model showed that there was a significant association between at-risk overweight children (P < 0.001), overweight children (P < 0.001), and caries in the primary dentition. Mean (SD) deft value of the sample was 1.08 (2.34), while the corresponding defs value was 1.43 (3.29).
Obesity appears to be associated with dental caries in the primary dentition of preschool Mexican children.
本研究旨在利用一组 4-5 岁学龄前儿童的队列数据，确定肥胖与龋齿之间的关联。
本研究的数据来源于一个由 1160 名儿童组成的队列。根据世界卫生组织的标准进行龋齿检测。龋病指数用龋齿（d）、缺失（e）和填充（f）的牙齿（t）（deft）或牙面（defs）的数量来衡量。体重指数（BMI）以 kg/m2 为单位，根据年龄和性别特定标准，儿童分为正常体重（第 5-85 百分位）、超重风险（>或= 第 85-<第 95 百分位）和超重（>或=第 95 百分位）。使用逻辑回归确定超重风险和超重儿童的比值比。
龋齿的患病率为 17.9%。男孩（19.6%）的龋齿比例略高于女孩（16.4%）。在总样本中，平均 BMI 为 17.10 +/- 3.83。约 53.7%的儿童被归类为正常体重，14.2%为超重风险，32.1%为超重。女孩中超重风险的儿童比例（17.1%）高于男孩（11.3%）。调整协变量后，逻辑回归模型显示，超重风险儿童（P < 0.001）和超重儿童（P < 0.001）与乳牙龋齿之间存在显著关联。样本的平均（SD）deft 值为 1.08（2.34），相应的 defs 值为 1.43（3.29）。
肥胖似乎与墨西哥学龄前儿童乳牙龋齿有关。
