Discrimination and (In)dignity in the Oral Health Care Setting and Oral Health Outcomes: A Latent Class Analysis

This study conducted a latent class analysis (LCA) on a large, nationally representative dataset of United States adults to determine whether there are distinct archetypes of oral health-related outcomes associated with discrimination and microaggression experiences in the oral health setting.

Respondents (18+ years) to the 2022 and 2023 rounds of the State of Oral Health Equity in America survey completed the 7-item Everyday Discrimination Scale-Oral Health (EDSOC) to assess discriminatory experiences, and the 4-item Dignity in Oral Care Scale (DOCS) to assess microaggression experiences. LCA model inputs were variables related to oral health, social determinants of health, socio-demographic factors and EDSOC and DOCS scores. Models were compared using multiple goodness-of-fit estimates.

The best-fitting model (N = 10 922; 50.9% female) produced 6 archetypes, generally representing shifts in demographic characteristics and discrimination and microaggression experiences in oral health settings. For example, while the "American Dream of Success" archetype consisted of mostly white adults aged 30 and above with regular access to dental care and fewer discriminatory and microaggression experiences, the "Vulnerable Adulthood" archetype consisted of younger (44 and below), more racially diverse adults with less access to dental care and more experiences with discrimination and microaggressions.

Results emphasise disproportionate discrimination and microaggression experiences in the oral health care system by younger and more diverse groups of adults compared to older, more non-Hispanic white adults. These findings emphasise the importance of oral health professionals providing culturally sensitive care that considers the intersectionality of all patients' backgrounds and experiences.
