Oral health disparities: Racial, language and nativity effects.

ABSTRACT: This study examined racial oral health disparities among Non-Hispanic Whites, Non-Hispanic Blacks, and Hispanics. For Hispanics, this study also examined the role of language in oral health disparities between English-speaking Hispanics and Spanish-speaking Hispanics. This study included 12, 307 adults older than 20 from the National Health and Nutrition Examination Survey (NHANES) 2011-2016. Oral health is measured by self-rated oral health, the frequencies of dentist visits, and the number of missed teeth. Exposures of interest referred to social gradients, which include education, annual family income, foreign born, and citizenship. Covariates included age, gender, and marital status. Ordinal logistic regression models were used to estimates the effects of social gradients on self-rated oral health and dentist visits. Negative binomial regression model was applied to estimate the effects of social gradients on the number of missed teeth. Overall, Spanish-speaking Hispanics presented the most disadvantaged social gradients and the worst oral health results. Non-Hispanic Blacks and English-speaking Hispanics reported disadvantaged oral health status when compared to Non-Hispanic Whites. Foreign-born, higher education levels and annual family income play protective role on oral health outcomes, while respondents who do not have citizenship are at higher risk of self-rated fair/poor oral health and dentist visits.

Project description:ObjectivesHospital emergency departments (EDs) are a place where many Americans seek treatment of dental conditions. Racial and ethnic minorities consistently have higher rates of ED utilization than whites for dental conditions. The reasons for these disparities and significant public health concerns are investigated less often. In this paper, we measure trends in racial disparities in ED discharges for dental conditions in Maryland from 2010 to 2013. To understand these disparities, we also describe differences between racial groups in age, gender, income, location, payer, comorbidities, and the availability of dental care.Methods2010-2013 State Emergency Department Data for Maryland were used in the analysis. Rates per 100,000 of the population are calculated using information from census population estimates. Cost-to-charge ratios are used to estimate the costs of ED discharges. Dental/oral health-related conditions (DOHRC) are defined as discharge diagnoses of ICD-9-CM codes 520.0 through 529.9. Descriptive statistics and fixed effects logistic regression models with a rare event correction are used to analyze the data.ResultsBlacks, especially females aged 25-34, have larger proportions of total ED discharges due to DOHRC, and higher population rates of DOHRC, than any other racial or ethnic group. In 2013, Blacks represented 30% of Maryland's population and accounted for 52% of ED costs for DOHRC. Hispanics and those of other races have much lower rates of DOHRC discharges. The regression results show that the high proportion of DOHRC discharges among Blacks may be explained by the concentration of Blacks in low-income central cities with less access to dental care.ConclusionThere are significant racial disparities in the ED utilization for DOHRC in Maryland. These disparities reflect the lack of access to dental care due to both cost and geographic limitations. This results in high healthcare costs and ineffective solutions for patients. Addressing oral health disparities will require policy solutions that are targeted to the populations most at need, and action plans that combine community and state level efforts.
