Abstract

Objectives

To examine bidirectional associations between dental caries and body mass index (BMI) among adolescents living in vulnerable communities in Brazil.

Methods

In a cohort study involving adolescents (n = 323), BMI, number of decayed teeth and odontogenic infections (PUFA/pufa index) were recorded at three time points between 12 and 15 years of age. Trajectories of dental caries, odontogenic infections, and BMI were developed using group-based trajectory modelling. Associations between dental caries and odontogenic infections trajectories with changes in BMI z-scores, and between BMI trajectories and dental caries and odontogenic infections incidence were adjusted for sugar intake and socioeconomic conditions using multiple Poisson regression.

Results

Three distinct trajectories of dental caries (stable low, moderate increasing, and high increase), odontogenic infections (stable low, stable moderate, and stable high), and BMI z-scores (stable low, stable moderate, and stable high) were identified. Compared with the stable moderate BMI z-score trajectory, the stable low was associated with increased risk of dental caries incidence (IRR 1.48, 95%CI 1.05–2.09). The high increase dental caries trajectory (IRR 1.38, 95%CI 1.02–1.88) and high stable odontogenic infections trajectory (IRR 1.50, 95%CI 1.12–2.00) were associated with positive changes in BMI z-scores.

Conclusions

Adolescents living in deprived communities with persistently low BMI were at higher risk of dental caries. Those with increasing dental caries and consistently high levels of odontogenic infections were at higher risk of BMI z-scores increases. Effective individual and public health strategies to reduce dental caries and malnutrition in adolescents should be aligned.

Clinical significance

Dental caries and body mass index are interrelated in underprivileged adolescents.

社会弱势青少年龋齿与体重指数的双向关联：一项基于群体的轨迹分析。

目的：研究生活在巴西脆弱社区的青少年龋齿与体重指数（BMI）之间的双向关系。方法：在一项涉及青少年的队列研究中（n=323），在12 - 15岁之间的三个时间点记录BMI、蛀牙数量和牙源性感染（PUFA/ PUFA指数）。龋齿、牙源性感染和BMI的发展轨迹采用基于群体的轨迹模型。利用多元泊松回归，根据糖摄入量和社会经济条件调整了龋病和牙源性感染轨迹与BMI z分数变化之间的关系，以及BMI轨迹与龋病和牙源性感染发生率之间的关系。结果：确定了三种不同的蛀牙轨迹（稳定低、中等增加和高增加）、牙源性感染（稳定低、稳定中、稳定高）和BMI z-score（稳定低、稳定中、稳定高）。与稳定的中等BMI z-score轨迹相比，稳定的低BMI z-score轨迹与龋齿发生率增加相关（IRR 1.48, 95%CI 1.05-2.09）。高增长的龋齿轨迹（IRR 1.38, 95%CI 1.02-1.88）和高稳定的牙源性感染轨迹（IRR 1.50, 95%CI 1.12-2.00）与BMI z-score的积极变化相关。结论：生活在贫困社区且持续低BMI的青少年患龋齿的风险较高。那些不断增加的龋齿和持续高水平的牙源性感染有更高的BMI z-score增加的风险。应为减少青少年龋齿和营养不良采取有效的个人和公共卫生战略。临床意义：贫困青少年患龋与体重指数相关。

期刊介绍： The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research. The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
