Insights
Psychosocial factors significantly impact early childhood caries (ECC) development. These social and psychological determinants influence behaviors and oral hygiene, contributing to ECC onset in children.
Area of Science:
- Pediatric Dentistry
- Public Health
- Social Epidemiology
Background:
- Early childhood caries (ECC) is a significant public health concern.
- Understanding the social determinants of ECC is crucial for effective prevention strategies.
Purpose of the Study:
- To investigate the social determinants of early childhood caries (ECC).
- To explore alternative pathways through which social factors influence ECC development.
Main Methods:
- Prospective study of initially caries-free children aged 1-4 years over 2 years.
- Regular assessments of caries, oral microbiology, oral hygiene behaviors, and psychosocial risk exposure.
- Utilized dental exams, saliva assays, interviews, and questionnaires.
Main Results:
- A composite measure of psychosocial risk was significantly associated with ECC onset.
- Psychosocial risk predicted ECC via pathways including poor diet, poor oral hygiene, and increased *Lactobacilli* concentrations.
- Multivariable regression supported the indirect influence of psychosocial risk on ECC onset.
Conclusions:
- Psychosocial factors are significant social determinants of ECC onset.
- Evidence suggests psychosocial influences on multiple purported risks for ECC.
- Highlights the importance of addressing social and psychological factors in ECC prevention.
Objective:
To examine the social determinants of early childhood caries (ECC), one of the greatest public health risks affecting children, and examine alternative pathways of influence.
Methods:
A physically healthy, socio-demographically high-risk sample of initially caries-free children, aged 1-4 years, was prospectively studied for 2 years. At 6-month intervals, assessments were made of caries presence from a standard dental exam; oral microbiology was assayed from saliva samples; oral hygiene behaviors and psychological and psychosocial risk exposure were derived from interviews and questionnaires.
Results:
189 children were enrolled; ECC onset occurred in 48 children over the 2-year study period. A composite measure of psychosocial risk was significantly associated with ECC onset over the course of the study (1.57, 95% CI 1.12-2.20, p < .001) and significantly associated with multiple risks for ECC, including poor diet/feeding (.92; 95% CI. 22-1.61, p < .01), poor oral hygiene (.39; 95% CI .09-.68), p < .05), and higher concentrations Lactobacilli (.96; 95% CI .43-1.49, p < .001). Multivariable regression analyses provided indirect support for the hypothesis that psychosocial risk exposure predicts ECC onset via behavioral and oral hygiene pathways.
Conclusions:
The study provides novel evidence that psychosocial factors influence many of the purported risks for ECC and strong evidence that there are social and psychological determinants of ECC onset.
