The effect of racial discrimination on mental and physical health: A propensity score weighting approach.

Chen, Shanting; Mallory, Allen B

RATIONALE The preponderance of research documents the negative consequences of racial discrimination for the mental and physical well-being across several racial/ethnic groups including Black Americans, Hispanic Americans, and Asian Americans. Despite this large body of research, few studies have attempted to evaluate racial discrimination as a casual factor of worse health among racial minority groups. The current study utilized nationally representative data to estimate the causal effect of racial discrimination on cardiovascular disease (CVD), self-rated physical health (SRH), body mass index (BMI), depression disorder, and substance use disorder. In addition, we examined whether the effect of racial discrimination on health was moderated by socio-demographic characteristics (i.e., age, race/ethnicity, sex, socioeconomic status, marital status, geographic location, and health insurance coverage). METHODS Data were from the combined National Survey of American Life and the National Latino and Asian American Study. We applied a propensity score weighting approach to estimate the differences between individuals who reported ever (N = 4358) or never (N = 1836) experiencing racial discrimination on a list of health outcomes (e.g., CVD, SRH, BMI, depression disorder, and substance use disorder). RESULTS Participants who reported ever experiencing racial discrimination were about 5 % higher CVD risk, had 0.12 points lower SRH, a 3 % higher probability of a depression disorder, and a 2 % higher probability of a substance use disorder. Moderation effects by race/ethnicity, sex, socioeconomic status, geographic region, and health insurance coverage were found. CONCLUSION Our study represents one of the first attempts to apply a propensity score weighting approach to causally link racial discrimination to worse health for racial minority individuals. This study adds to a larger body of research documenting the negative association between racial discrimination and health.
