Perceived discrimination has been studied with regard to its impact on several types of health effects. This meta-analysis provides a comprehensive account of the relationships between multiple forms of perceived discrimination and both mental and physical health outcomes. In addition, this meta-analysis examines potential mechanisms by which perceiving discrimination may affect health, including through psychological and physiological stress responses and health behaviors. Analysis of 134 samples suggests that when weighting each study's contribution by sample size, perceived discrimination has a significant negative effect on both mental and physical health. Perceived discrimination also produces significantly heightened stress responses and is related to participation in unhealthy and nonparticipation in healthy behaviors. These findings suggest potential pathways linking perceived discrimination to negative health outcomes.

Perceived discrimination and health: a meta-analytic review.

Despite a growing body of epidemiological evidence in recent years documenting the health impacts of racism, the cumulative evidence base has yet to be synthesized in a comprehensive meta-analysis focused specifically on racism as a determinant of health. This meta-analysis reviewed the literature focusing on the relationship between reported racism and mental and physical health outcomes. Data from 293 studies reported in 333 articles published between 1983 and 2013, and conducted predominately in the U.S., were analysed using random effects models and mean weighted effect sizes. Racism was associated with poorer mental health (negative mental health: r = -.23, 95% CI [-.24,-.21], k = 227; positive mental health: r = -.13, 95% CI [-.16,-.10], k = 113), including depression, anxiety, psychological stress and various other outcomes. Racism was also associated with poorer general health (r = -.13 (95% CI [-.18,-.09], k = 30), and poorer physical health (r = -.09, 95% CI [-.12,-.06], k = 50). Moderation effects were found for some outcomes with regard to study and exposure characteristics. Effect sizes of racism on mental health were stronger in cross-sectional compared with longitudinal data and in non-representative samples compared with representative samples. Age, sex, birthplace and education level did not moderate the effects of racism on health. Ethnicity significantly moderated the effect of racism on negative mental health and physical health: the association between racism and negative mental health was significantly stronger for Asian American and Latino(a) American participants compared with African American participants, and the association between racism and physical health was significantly stronger for Latino(a) American participants compared with African American participants.

Racism as a Determinant of Health: A Systematic Review and Meta-Analysis

In 2 meta-analyses, we examined the relationship between perceived discrimination and psychological well-being and tested a number of moderators of that relationship. In Meta-Analysis 1 (328 independent effect sizes, N = 144,246), we examined correlational data measuring both perceived discrimination and psychological well-being (e.g., self-esteem, depression, anxiety, psychological distress, life satisfaction). Using a random-effects model, the mean weighted effect size was significantly negative, indicating harm (r = -.23). Effect sizes were larger for disadvantaged groups (r = -.24) compared to advantaged groups (r = -.10), larger for children compared to adults, larger for perceptions of personal discrimination compared to group discrimination, and weaker for racism and sexism compared to other stigmas. The negative relationship was significant across different operationalizations of well-being but was somewhat weaker for positive outcomes (e.g., self-esteem, positive affect) than for negative outcomes (e.g., depression, anxiety, negative affect). Importantly, the effect size was significantly negative even in longitudinal studies that controlled for prior levels of well-being (r = -.15). In Meta-Analysis 2 (54 independent effect sizes, N = 2,640), we examined experimental data from studies manipulating perceptions of discrimination and measuring well-being. We found that the effect of discrimination on well-being was significantly negative for studies that manipulated general perceptions of discrimination (d = -.25), but effects did not differ from 0 when attributions to discrimination for a specific negative event were compared to personal attributions (d = .06). Overall, results support the idea that the pervasiveness of perceived discrimination is fundamental to its harmful effects on psychological well-being.

Racism and Health: Evidence and Needed Research.

This article reviews the scientific research that indicates that despite marked declines in public support for negative racial attitudes in the United States, racism, in its multiple forms, remains embedded in American society. The focus of the article is on the review of empirical research that suggests that racism adversely affects the health of nondominant racial populations in multiple ways. First, institutional racism developed policies and procedures that have reduced access to housing, neighborhood and educational quality, employment opportunities, and other desirable resources in society. Second, cultural racism, at the societal and individual level, negatively affects economic status and health by creating a policy environment hostile to egalitarian policies, triggering negative stereotypes and discrimination that are pathogenic and fostering health-damaging psychological responses, such as stereotype threat and internalized racism. Finally, a large and growing body of evidence indicates that experiences of racial discrimination are an important type of psychosocial stressor that can lead to adverse changes in health status and altered behavioral patterns that increase health risks.

Racism and Health I: Pathways and Scientific Evidence

Objective: This research examined the impact of perceived discrimination on ambulatory blood pressure (ABP) and daily level affect during social interaction. Design: For 24 hrs, adult Black and White participants wore an ABP monitor and completed palm pilot diary entries about their social interactions. Main Outcome Measures: Mean level and time-trend trajectories of blood pressure and heart rate were examined as well as mean level measures of positive and negative affect after stressful and nonstressful social interactions. Results: Analyses showed that, after controlling for important covariates, perceived discrimination predicted the slopes of both wake and nocturnal ABP responses, with those who reported more discrimination having steeper daytime trajectories for systolic and diastolic blood pressure and less nighttime dipping in heart rate over time as compared to those who had reported relatively infrequent discrimination. High levels of perceived discrimination were also related to positive and negative affective responses after stressful encounters. Conclusions: These results suggest that, regardless of race, perceived discrimination is related to cardiovascular and affective responses that may increase vulnerability to pathogenic processes.

The Effects of Perceived Discrimination on Ambulatory Blood Pressure and Affective Responses to Interpersonal Stress Modeled Over 24 Hours.

This research examined effects of discrimination on food decisions. In Study 1, reflecting upon past experiences of discrimination, as compared to a neutral topic, caused an increased desire to consume unhealthy foods. In Study 2, participants received a negative evaluation from a biased or fair grader. Past experiences with discrimination moderated how people responded to the feedback. Those participants who had infrequent past experiences with discrimination were most likely to endorse unhealthy food options after receiving the biased evaluation. Those who scored high on past discrimination were unaffected by experimental condition and endorsed similar numbers of healthy and unhealthy food options after receiving the evaluative feedback. When offered an actual snack, those who accepted one were more likely to choose an unhealthy option following discrimination, regardless of past discrimination level. These results suggest that discrimination may be affecting self-regulatory capacity in regard to food c...

Effect of Discrimination on Food Decisions

Interpersonal Discrimination and Physical Health

OBJECTIVE
This article comprehensively examines the relationship between interpersonal discrimination (IPD) and health-related behavior (HB), expanding upon Pascoe and Richman's (2009) meta-analysis and research synthesis.


METHOD
One hundred and twenty one articles providing zero-order correlations (or information allowing their calculation) between perceptions of IPD and a variety of HB outcomes were coded and analyzed using a random-effects meta-analysis model. One hundred and fifty six articles examining this relationship using multivariate models were also coded and summarized within a research synthesis. Subanalyses were performed for articles examining smoking, alcohol use/abuse, substance use/abuse, sexual risk, and diet/eating behaviors. Potential mediators of the IPD-HB relationship were also tallied when available.


RESULTS
Compared to the original analysis, results suggest an overall attenuated but stable relationship between IPD and HBs.


CONCLUSIONS
The documented meta-analytic associations between perceptions of IPD and a variety of HB provide supportive evidence for one pathway through which IPD heightens risk for negative physical health outcomes among marginalized groups. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
