Abstract

Objective

This study aimed to explore the longitudinal impact of changes in household income poverty and area-based socioeconomic deprivation on dental caries prevalence in early childhood.

Methods

Data from the Growing Up in Scotland (GUS) longitudinal study (2005/6-2009/10) were linked to dental caries experience data at age 5 from Scotland's National Dental Inspection Programme. Latent Class Analysis identified trajectories of household poverty (income below 60% of the national median) and area-based deprivation across multiple time points between birth and age 5. Cumulative exposure scores were also calculated, and modified Poisson regression assessed associations between socioeconomic pathways and caries experience in 2893 children.

Results

Children living in persistent household poverty or in socioeconomically deprived areas had the highest caries experience risk compared to children never in poverty or deprivation. Elevated caries risk was also observed in children falling into poverty (aRR = 1.4; 95% CI = [1.1–1.8]) and escaping poverty (aRR = 1.6; 95% CI = [1.3–2.1]). Children moving into more deprived areas had higher caries risk (aRR = 1.6; 95% CI = [1.2–2.2]), while moving out of deprived areas did not increase risk (aRR = 1.1; 95% CI = [0.8–1.7]). Caries risk increased with years spent in household poverty and in deprived areas.

Conclusions

Unstable poverty and downward socioeconomic deprivation mobility were associated with greater caries risk in early childhood, underscoring the importance of considering the duration and persistence of socioeconomic disadvantage in relation to oral health outcomes and should inform early-years focused policies to address these. Longitudinal data linkage combining representative surveys and routine data is a powerful way to uncover these issues.

家庭贫困和地区贫困与儿童龋齿的早期生活轨迹：一项纵向数据联系队列研究。

目的：本研究旨在探讨家庭收入贫困和基于地区的社会经济剥夺变化对儿童早期龋患病率的纵向影响。方法：来自苏格兰成长（GUS）纵向研究（2005/6-2009/10）的数据与来自苏格兰国家牙科检查计划的5岁龋齿经历数据相关联。潜在阶级分析确定了从出生到5岁之间多个时间点的家庭贫困（收入低于全国中位数的60%）和地区贫困的轨迹。还计算了累积暴露得分，并使用修正泊松回归评估了2893名儿童的社会经济途径与龋齿经历之间的关系。结果：生活在持续贫困家庭或社会经济贫困地区的儿童与从未处于贫困或贫困状态的儿童相比，患龋的风险最高。贫困儿童患龋齿的风险也较高(aRR = 1.4；95% CI =[1.1 - -1.8])和逃离贫困(aRR = 1.6;95% ci =[1.3-2.1])。迁入贫困地区的儿童患龋齿的风险更高(aRR = 1.6；95% CI =[1.2-2.2])，而迁出贫困地区不增加风险(aRR = 1.1；95% ci =[0.8-1.7])。在贫困家庭和贫困地区生活的时间越长，龋齿风险越高。结论：不稳定的贫困和向下的社会经济剥夺流动性与儿童早期更大的龋齿风险相关，强调了考虑与口腔健康结果相关的社会经济劣势的持续时间和持久性的重要性，并应告知早期重点政策以解决这些问题。将代表性调查和常规数据相结合的纵向数据链接是发现这些问题的有力方法。

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.
