Discrimination, perceived control, and psychological health among African Americans with hypertension

Discrimination and Cardiovascular Health in Black Americans: Exploring Inflammation as a Mechanism and Perceived Control as a Protective Factor

OBJECTIVE

Inflammation may be an integral physiological mechanism through which discrimination impacts cardiovascular health and contributes to racial health disparities. Limited research has examined psychosocial factors that protect against the negative effects of discrimination on inflammation. Perceived control is a promising possible protective factor, given that it has been shown to moderate the relationship between other psychosocial stressors and physiological outcomes. This study thus tested whether systemic inflammation mediated the link between discrimination and cardiovascular health and whether perceived control moderated this relationship.

METHODS

Data for this project included 347 non-Hispanic/Latinx Black adults (mean [standard deviation] age = 51.64 [11.24] years; 33% female) taken from the Midlife in the United States study. Perceived control and daily discrimination were assessed via self-report, and inflammation was measured via circulating levels of C-reactive protein (CRP), interleukin-6 (IL-6), fibrinogen, and tumor necrosis factor α. Cardiovascular health was measured by morbidity of cardiovascular conditions: heart disease, hypertension, and/or stroke.

RESULTS

CRP (indirect effect: b = 0.004, 95% confidence interval [CI] = 0.001-0.007) and fibrinogen (indirect effect: b = 0.002, 95% CI = 0.0003-0.005) mediated the link between discrimination and cardiovascular conditions. Perceived control moderated the relationship between discrimination and CRP ( F (1, 293) = 4.58, Δ R2 = 0.013, b = -0.02, SE = 0.01, p = .033). CRP mediated the link between discrimination and cardiovascular conditions only for those who reported low levels of perceived control (Index = -0.003, 95% CI = -0.007 to -0.0001).

CONCLUSION

Findings provide empirical evidence of inflammation as a mechanism linking discrimination to cardiovascular conditions among Black Americans. Additionally, perceived control may be protective. Findings could suggest beliefs about control as a potential intervention target to help reduce the negative effects of discrimination on cardiovascular health among Black Americans.

The role of sense of community in improving the health-related quality of life among Black Americans

Black Americans have the lowest life expectancy and health-related quality of life (HRQoL; a strong predictor of premature mortality) of any racial/ethnic group in the United States. Low rates of physical activity and engagement in healthy eating are two known contributors to low HRQoL. Black Americans are more likely to live in environments that inhibit engagement in these two contributors. The present study examined sense of community as a buffer against the adverse effects of low physical activity and healthy eating on HRQoL among Black Americans. A sample of 290 Black American adults were recruited for the present study. Results indicate that sense of community buffers against the adverse effects of low physical activity on HRQoL. The results of the present study can be used by health promotion interventionists and policy-makers to improve HRQoL and reduce premature mortality among Black Americans.

When women support the status quo: Gender moderates the relationship between openness to experience and system-justifying beliefs

Although epistemic needs motivate the endorsement of system-justifying beliefs, few studies have investigated moderators of this association. Here, we argue that because being the target of discrimination should undermine one’s sense of control, the association between epistemic needs and system-justifying beliefs should be stronger for disadvantaged (vs. advantaged) groups. As hypothesized, analyses of a nation-wide random sample of adults ( N = 14,929) revealed that the negative relationship between openness to experience (i.e., an indicator of low epistemic needs) and multiple system-justifying beliefs (i.e., gender-based system justification, right-wing political preference, and conservative party support) was stronger for women (vs. men), and that these moderated associations were mediated by perceptions of gender discrimination. Our results suggest that women may sometimes endorse beliefs that conflict with their self and group interests in order to satisfy their epistemic needs.

Witnessed Incivility and Perceptions of Patients and Visitors in Hospitals

Research has examined instances of incivility witnessed by physicians, nurses, or employees in hospitals. Although patients and visitors are members in hospitals, witnessed incivility from their perspective has rarely been empirically investigated. The aims of the current study are 2-fold: (1) to investigate the forms of incivility patients/visitors witness in hospitals and (2) to examine whether these patients/visitors believe these incivilities impact the target’s sense of perceived control. An integration of interpretative phenomenological analysis and thematic analysis was used to code qualitative data (N = 77). Eight themes of witnessed incivility and 3 themes for impact on perceived control were identified. The results illuminate patterns of incivility targeted at marginalized groups, historically underrepresented in hospital-focused incivility research (eg, homeless individuals, incarcerated individuals, the elderly individuals). The majority of witnesses believed the incident of incivility would negatively impact the target’s perception of control, possibly affecting their experience and health. The current study demonstrates that empirically investigating witnessed incivility from the patient/visitor perspective provides critical information about the unique patterns of mistreatment occurring within hospital contexts.
