BACKGROUND
The association between low birth weight (LBW) and dental caries is currently unclear. The aim of this study was to investigate the association of LBW with dental caries in permanent teeth in children of Ningbo city.
METHODS
A total of 1975 children aged 11-to-13 years in Ningbo, China were enrolled in this cross-sectional study. LBW was defined as a birthweight< 2500 g. Ten dentists assessed the status of dental caries in permanent teeth in line with the World Health Organization (WHO) criteria and guidelines. Decayed, missing or filled teeth were considered to have dental caries. Parental questionnaires were used to collect child information. Non-conditional logistic regression analysis was used to estimate odds ratios (ORs) and the corresponding 95% confidence intervals (CIs).
RESULTS
Dental caries in permanent teeth was found in 610 children (30.9%), with a mean DMFS of 2.09 (SD = 1.2). The adjusted ORs for dental caries in permanent teeth was 1.46 (95% CI 1.00, 2.13) for LBW.
CONCLUSIONS
LBW was not associated with dental caries in permanent teeth in the study population.
背景
低出生体重（LBW）与龋齿之间的关系目前尚不清楚。本研究旨在探讨宁波市儿童 LBW 与恒牙龋齿之间的关系。
方法
本横断面研究共纳入宁波市 1975 名 11-13 岁儿童。LBW 定义为出生体重<2500g。10 名牙医按照世界卫生组织（WHO）标准和指南评估恒牙龋齿状况。龋齿、缺失或填补的牙齿被认为患有龋齿。使用父母问卷收集儿童信息。采用非条件 logistic 回归分析估计比值比（OR）及其相应的 95%置信区间（CI）。
结果
恒牙龋齿在 610 名儿童（30.9%）中发现，DMFS 平均值为 2.09（SD=1.2）。调整后的 OR 显示，LBW 与恒牙龋齿的关联为 1.46（95%CI 1.00，2.13）。
结论
在本研究人群中，LBW 与恒牙龋齿之间无关联。
