State-Level Structural Racism and Children's Dental Care Access and Oral Health.

Abstract

Introduction: Black children in the United States have lower rates of dental visits and higher rates of poor oral health. However, few studies have examined the role of structural racism as a contributor to racial gaps in children's oral health. This study assessed associations between state-level structural racism and oral health outcomes of children and the related Black-White disparities.

Methods: This repeated cross-sectional observational study examined children aged 1 to 17 y in the 2016 to 2021 National Survey of Children's Health (NSCH). Three outcomes were examined: utilization (dentist visit in past 12 mo), any oral health problem (difficulty in past 12 mo with bleeding gums, cavities, or toothaches), and oral health (teeth in excellent or very good condition). A state-level index was constructed to measure Black-White structural racism composed of 5 dimensions (judicial, educational, economic, political, and neighborhood segregation) and linked to the NSCH. Estimated population-weighted logit regression models were used to assess associations between the outcomes and race and structural racism, adjusting for demographics and socioeconomic status.

Results: The dataset consisted of 98,423 Black (11%) or White (88%) children. Black children had relatively worse outcomes than White children did, with the largest difference observed for the children having teeth in excellent or very good condition (73% vs. 83%). State-level structural racism was not statistically significantly associated with a child receiving dental care, having any oral health problem, or having teeth in excellent or very good condition. US Black-White disparities in these outcomes were unchanged after adjustment for state-level structural racism.

Conclusions: Expanded efforts are needed to address US Black-White disparities in child oral health outcomes. State-level structural racism was not associated with these outcomes. Future research should explore whether findings change when examining these associations at a different geographic level and whether indices of structural racism should explicitly include items specific to health care access and child-specific institutional domains.

Knowledge transfer statement: Black children in this US study had relatively worse oral health and were less likely to have a dental visit than White children were. Structural racism did not explain these disparities, which suggests the need for further research to study mechanisms driving these disparities and how to address them. Policy makers should consider policies that expand where care is delivered, who delivers care, and increase dentists' Medicaid participation, strategies identified previously for reducing disparities.
