Abstract

Objectives: The aim of this study was to investigate the link between prolonged breastfeeding (≥ 12 months) and early childhood caries (ECC) using propensity score matching (PSM) to account for observed confounders, reduce bias, and provide a more reliable estimate of this relationship.

Methods: This study utilised data from the French Longitudinal Study of Children (ELFE Cohort), comprising 11 718 participants. PSM was employed to pair children who were breastfed for 12 months or longer with those breastfed for less than 12 months or not at all, controlling for shared risk factors such as socioeconomic status and dietary habits. Logistic regression models were conducted to examine the association between ECC, reported by the parents at 3.5 years, and prolonged breastfeeding.

Results: Infants (7.6%) who were breastfed for 12 months or more exhibited twice the odds of developing ECC at 3.5 years compared to those breastfed for less than 12 months or not at all (OR = 2.20, 95% CI: 1.39, 3.47).

Conclusion: Children breastfed for 12 or more months are at increased risk of developing ECC. Further research is needed to investigate specific breastfeeding practices that may contribute to this increased risk, with the aim of promoting prolonged breastfeeding while ensuring optimal oral health.

在法国儿童纵向研究（ELFE队列）中，使用倾向评分匹配分析延长母乳喂养与早期儿童龋齿的关系。

目的：本研究的目的是研究延长母乳喂养（≥12个月）和早期儿童龋齿（ECC）之间的联系，使用倾向评分匹配（PSM）来解释观察到的混淆因素，减少偏差，并提供更可靠的这种关系的估计。方法：本研究利用了法国儿童纵向研究（ELFE队列）的数据，包括11718名参与者。采用PSM将母乳喂养12个月或更长时间的儿童与母乳喂养不足12个月或根本不母乳喂养的儿童配对，控制社会经济地位和饮食习惯等共同的风险因素。采用Logistic回归模型检验父母在3.5岁时报告的ECC与延长母乳喂养之间的关系。结果：母乳喂养12个月或更长时间的婴儿（7.6%）在3.5岁时发生ECC的几率是母乳喂养少于12个月或根本没有母乳喂养的婴儿的两倍（or = 2.20, 95% CI: 1.39, 3.47）。结论：母乳喂养12个月以上的儿童发生ECC的风险增加。需要进一步的研究来调查可能导致这种风险增加的具体母乳喂养做法，目的是在确保最佳口腔健康的同时促进延长母乳喂养。

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.
