Abstract
BACKGROUND: American Indian and Alaska Native (AIAN) communities face pronounced economic and health disparities compared to White Americans, a situation rooted in long-standing historical injustices and segregation. The theory of Minorities' Diminished Returns (MDR) provides insight beyond the traditional focus on socioeconomic status (SES) disparities, such as educational attainment. It suggests that the beneficial outcomes of educational achievements on health and economic status are less substantial for marginalized and racially non-White groups compared to White Americans. AIMS: This study investigates the applicability of the MDR theory to AIAN populations by examining whether the positive effects of education on poverty reduction and the decreased risk of disability benefit dependency are weaker for AIAN adults relative to their White counterparts. METHODS: Utilizing data from the 2022 National Health Interview Survey (NHIS), this cross-sectional study analyzed a cohort of 20,743 adults, comprising 20,474 White and 269 AIAN individuals. We assessed the relationships between educational attainment, poverty level, and the likelihood of receiving disability benefits. A structural equation model was employed, with receipt of disability benefits as a latent factor influenced by racial background (AIAN) as a potential moderator, education as the main predictor, and poverty level and self-rated health as mediators. Gender, age, employment status, marital status, and Hispanic ethnicity served as additional covariates. RESULTS: Findings indicate that higher educational levels are generally associated with a lower likelihood of receiving disability benefits, mediated by improved health and economic status. Nonetheless, the interaction between race (AIAN) and education significantly influenced economic outcomes, subsequently affecting the risk of receiving disability benefits. This suggests that Whites benefit more economically from education than AIAN individuals do. CONCLUSION: The study underscores the MDR theory's relevance to the disparities in educational outcomes related to poverty risk and receiving disability benefits among AIAN populations. The challenges AIAN individuals face in leveraging their educational achievements for economic gain relative to Whites may be attributed to pervasive racism and discrimination within various sectors, including employment and education. Addressing these disparities necessitates policy interventions that ensure educational returns are equitable across racial groups, with a focus on equal access to resources and opportunities.
