Abstract

Objectives: Oral health is an important part of general health and well-being and shares risk factors, such as poor diet, with obesity. The published literature assessing the association between obesity and oral health in early childhood is sparse and inconsistent. The objective of this study was to investigate associations between overweight/obesity (measured by body mass index) and dental outcomes (caries, plaque index and gingival index) both cross-sectionally and longitudinally, taking account of potential confounding factors, based on data collected at age 2 and age 5 within the Australian Study of Mothers' and Infants' Life Events Affecting Oral Health (SMILE) birth cohort study.

Methods: This study used data from 1174 SMILE participants. Associations between overweight/obesity and dental outcomes were assessed using generalized linear regression models for the modified Poisson family with log link to estimate prevalence ratios. Cross-sectional and longitudinal models were fitted, after minimal and full adjustment for potential confounders.

Results: Approximately 12% of the participants were overweight/obese at 2 years and 9% at 5 years. Between 2 and 5 years, the prevalence of caries increased from approximately 4% to 24%, at least mild plaque accumulation increased from 37% to 90% and at least mild inflammation from 27% to 68%. There were no associations between overweight/obesity and the prevalence of dental caries; prevalence ratios (PR) [95% confidence interval (CI)] after adjustment for age and sex were 0.9 (0.3, 2.4) cross-sectionally at 2 years, 1.0 (0.6, 1.5) cross-sectionally at 5 years, and 1.0 (0.6, 1.5) for overweight/obesity at 2 years and caries at 5 years. Prevalence ratios were all around the value of 1 for the other dental outcomes and also after adjustment for additional confounders.

Conclusions: There were no associations between overweight/obesity and dental caries, plaque index or gingival index in this cohort of preschool children. However, associations may emerge as the children become older, and it will be possible to extend analyses to include data collected at age 7 in the near future.

幼儿期超重/肥胖与牙病之间的关系：澳大利亚队列研究的结果。

目标：口腔健康是整体健康和幸福的重要组成部分，与肥胖有着共同的风险因素，如不良饮食。已发表的评估幼儿期肥胖与口腔健康之间关系的文献很少，而且不一致。本研究的目的是根据澳大利亚影响口腔健康的母婴生活事件研究（SMILE）出生队列研究中收集的 2 岁和 5 岁儿童的数据，调查超重/肥胖（以体重指数衡量）与牙科结果（龋齿、牙菌斑指数和牙龈指数）之间的横向和纵向关联，同时考虑潜在的混杂因素：本研究使用了 1174 名 SMILE 参与者的数据。使用修正泊松族的广义线性回归模型评估了超重/肥胖与牙科结果之间的关系，并使用对数链接估算了患病率比率。在对潜在混杂因素进行最小调整和完全调整后，对横截面和纵向模型进行了拟合：大约 12% 的参与者在 2 年时超重/肥胖，9% 的参与者在 5 年时超重/肥胖。2至5年间，龋齿患病率从约4%上升至24%，至少轻度牙菌斑堆积从37%上升至90%，至少轻度炎症从27%上升至68%。超重/肥胖与龋齿患病率之间没有关联；对年龄和性别进行调整后，2 年的横截面患病率比 (PR) [95% 置信区间 (CI)]为 0.9 (0.3, 2.4)，5 年的横截面患病率比为 1.0 (0.6, 1.5)，2 年的超重/肥胖和 5 年的龋齿患病率比为 1.0 (0.6, 1.5)。其他牙科结果的患病率比值都在 1 左右，在对其他混杂因素进行调整后也是如此：结论：在这批学龄前儿童中，超重/肥胖与龋齿、牙菌斑指数或牙龈指数之间没有关联。然而，随着儿童年龄的增长，两者之间可能会出现关联，因此有可能在不久的将来将分析范围扩大到7岁时收集的数据。

期刊介绍： The aim of Community Dentistry and Oral Epidemiology is to serve as a forum for scientifically based information in community dentistry, with the intention of continually expanding the knowledge base in the field. The scope is therefore broad, ranging from original studies in epidemiology, behavioral sciences related to dentistry, and health services research through to methodological reports in program planning, implementation and evaluation. Reports dealing with people of all age groups are welcome. The journal encourages manuscripts which present methodologically detailed scientific research findings from original data collection or analysis of existing databases. Preference is given to new findings. Confirmations of previous findings can be of value, but the journal seeks to avoid needless repetition. It also encourages thoughtful, provocative commentaries on subjects ranging from research methods to public policies. Purely descriptive reports are not encouraged, nor are behavioral science reports with only marginal application to dentistry. The journal is published bimonthly.
