The Impact of Racially Motivated Housing Discrimination on Allostatic Load among Indigenous University Students

Allostatic load (AL) is an aggregate measure of wear and tear on the body due to the chronic activation of the stress response system. The goal of this study was to examine the association between racially motivated housing discrimination (HD) and AL score within a sample of Indigenous university students. Data for this cross-sectional study were collected from Indigenous adults attending university in a small city in western Canada between 2015 and 2017 (N = 104; mean age = 27.8 years). An item adapted from the Experience of Discrimination Scale was to assess racially motivated HD in the past 12 months. AL was measured as a composite of 7 biomarkers assessing neuroendocrine, cardiovascular, metabolic, and immune system function. Bias-corrected and accelerated bootstrapped linear regression models were used to examine associations adjusting for age, income, parenthood, and other situations in which discrimination had been experienced. Indigenous university students who experienced racially motivated HD in the past year (16.8% of the sample) had an average AL score of approximately 4, which was almost double that of their peers who had not. In an adjusted model, racially motivated HD was associated with a 1.5 point increase in AL score. This model explained 35% of the adjusted variance in AL score, of which racially motivated HD explained 24%. These results suggest Indigenous adults who experienced racially motivated HD in the past year had early and more pronounced wear and tear on neuroendocrine, cardiovascular, metabolic, and immune system functioning in young and middle adulthood than Indigenous peers who did not. These findings combine with others to highlight the need for increased efforts to prevent racially motivated HD in urban centers.

Racially-motivated housing discrimination experienced by Indigenous postsecondary students in Canada: impacts on PTSD symptomology and perceptions of university stress

OBJECTIVES

To examine the impacts of housing discrimination experienced by Indigenous postsecondary students on post-traumatic stress disorder (PTSD) symptomology and perceptions of university stress.

STUDY DESIGN

Cross-sectional study.

METHODS

Data were gathered via in-person surveys completed by 142 Indigenous students between 2015 and 2017. Associations were analyzed using phi coefficients and linear regression models adjusted for confounders. Qualitative data were examined using thematic analyses.

RESULTS

Indigenous students who had children (almost 50% of the sample), were living with a romantic partner, and/or were between the ages of 25-44 years experienced significantly more racially-motivated housing discrimination than other Indigenous students in the sample. The frequency of housing discrimination in the past 12 months was significantly associated with increased PTSD symptoms; particularly, intrusive recollection and more perceived stress at university in linear regression models adjusted for confounders. Every 1-point increase in the frequency of housing discrimination on a 4-point scale resulted in a 5.4-point increase in PTSD score. Although living with a romantic partner resulted in more housing discrimination, it also served as a resilience factor, buffering the impact of housing discrimination on PTSD symptomology. Qualitative data indicated students faced Racially-motivated housing discrimination that was blunt and deliberate and highlighted the resourceful ways students sought to resist it.

CONCLUSIONS

Racially-motivated housing discrimination exacerbated PTSD symptomology among Indigenous students and adversely impacted perceptions of their university experience. Efforts are needed to address housing discrimination directly, as well as provide greater family-focused housing and mental wellness supports to Indigenous students to reduce potential impacts of this public health problem on postsecondary success and degree completion.
