Mediators of discrimination and self-rated health among African Americans

Perceived racial/ethnic discrimination and cigarette smoking behaviors among a sample of people with HIV

This study was a secondary analysis of baseline data from a clinical trial of an intensive group-based smoking cessation treatment for people with HIV (PWH) who smoke. It examined the cross-sectional relationship between perceived ethnic discrimination (PED) and cigarette smoking variables (i.e., nicotine dependence, motivation to quit smoking, self-efficacy to quit smoking) among PWH and explored whether depressive symptoms mediated the relationship between PED and smoking variables. Participants (N = 442; Mage = 50.6; 52.8% Male; 56.3% Black, non-Hispanic; 6.3% White, non-Hispanic; 13.3% Hispanic; 87.7% unemployed; 81.6% single) completed measures of demographics, cigarette smoking, depressive symptoms, and PED. Greater PED was related to lower self-efficacy to quit smoking, greater perceived stress, and greater depressive symptoms. In addition, depressive symptoms mediated the relationship between PED and two cigarette smoking variables (i.e., nicotine dependence, self-efficacy to quit smoking). Findings highlight the need for smoking interventions to target PED, self-efficacy, and depressive symptoms to improve smoking cessation variables among PWH.

Relational and individual stress pathways linking discrimination and ageing cardiometabolic health

Perceived discrimination is a significant risk factor for worse ageing health outcomes. Yet, the specific individual and relational stress pathways linking discrimination to disease are less understood, especially in the context of cardiometabolic health. We tested family stress and psychophysiological distress (negative affect and high-risk lipid/fat metabolism) as mediators linking perceived discrimination to cardiometabolic morbidity and health appraisal over 20 years for midlife adults. Using data from participants who completed the Biomarker Project (2004-2009) of the Midlife in the U.S. project, and examining data over the study's three waves (1995-1996, 2004-2006, and 2013-2014), we used structural equation modelling to test pathways for participants who reported zero cardiometabolic conditions at baseline (n = 799). Greater Time 1 discrimination was associated with greater Time 2 family strain, which was in turn associated with worse negative affect; worse Time 2 negative affect was associated with worse Time 3 health appraisal; metabolic lipids risk did not serve as an indirect pathway to Time 3 cardiometabolic morbidity (χ²  = 147.74, p < 0.001; RMSEA = 0.056; CFI = 0.902; SRMR = 0.047). The inclusion of family in interventions to mitigate the impact of discrimination may be indicated for promoting cardiometabolic wellness.

Minority stress process among older Black Americans: the role of age, perceived discrimination, and anxiety

Objective: Prolonged experiences of discrimination can be a major source of physical and health-related stress, particularly in older Black Americans. However, there is limited information on the relation between discrimination and anxiety, particularly within the context of other constructs that influence the manifestation of anxiety symptoms. For example, several studies have suggested that ethnic identification may provide psychological and social resources to deal with the effects of discrimination. This study aims to further understand these processes.Method: This study utilized structural equation modeling (SEM) to examine predictors of anxiety symptom severity in a sample of African American and Afro-Caribbean adults aged 55 and older from the National Survey of American Life (N = 1,032).Results: The final structural regression model revealed acceptable fit indices, and was successful in measuring latent anxiety symptom severity, showing that more experienced discrimination was related to higher anxiety and anxiety was directly related to mental health rating. While higher experience of discrimination was associated with higher anxiety, it was not directly related to mental health rating. However, contrary to expectation, ethnic identification did not serve as a protective factor between experienced discrimination and anxiety. As individuals aged, they experienced less discrimination and reported poorer self-rated mental health.Conclusions: While age served as a protective factor for perceived discrimination and anxiety symptom severity, ethnic identification did not. Implications for those working to reduce anxiety symptoms among Black Americans are discussed.

Psychosocial factors associated with genetic testing status among African American women with ovarian cancer: Results from the African American Cancer Epidemiology Study

BACKGROUND

Racial disparities in the uptake of cancer genetic services are well documented among African American (AA) women. Understanding the multiple social and psychological factors that can influence the uptake of genetic testing among AA women is needed.

METHODS

Data came from 270 AA women diagnosed with ovarian cancer and participating in a population-based, case-control study of ovarian cancer who were asked about genetic testing. Logistic regression analyses tested the associations of predisposing, enabling, and need factors with reported genetic testing uptake.

RESULTS

One-third of the sample (35%) reported having had genetic testing. In the multivariable model, AA women with higher incomes had more than double the odds of being tested than those with the lowest income (odds ratio [OR] for $25,000-$74,999, 2.04; 95% confidence interval [CI], 1.06-3.99; OR for ≥$75,000, 2.32; 95% CI, 0.92-5.94). AA women who reported employment discrimination were significantly less likely to report genetic testing than those who did not report job discrimination (OR, 0.39; 95% CI, 0.14-0.95). Marital status, Medicaid versus other insurance, prayer frequency, and perceived social support were significantly associated with genetic testing uptake in bivariate analyses but were not significant contributors in multivariable analyses.

CONCLUSIONS

Consistent with other studies of AA women, a minority of African American Cancer Epidemiology Study participants had undergone genetic testing. Having a lower income and experiencing job discrimination decreased the likelihood of testing. These results provide foundational evidence supporting the need for interventions to improve the uptake of genetic testing among AA women by reducing cost barriers and providing credible assurances that genetic results will be kept private and not affect social factors such as employability.

The pathways from perceived discrimination to self-rated health among the Chinese diaspora during the COVID-19 pandemic: investigation of the roles of depression, anxiety, and social support

BACKGROUND

Research indicates the adverse impacts of perceived discrimination on health, and discrimination inflamed by the COVID-19 pandemic, a type of social exclusion, could affect the well-being of the Chinese diaspora. We analyzed the relationship and pathways of perceived discrimination's effect on health among the Chinese diaspora in the context of the pandemic to contribute to the literature on discrimination in this population under the global public health crisis.

METHODS

We analyzed data from 705 individuals of Chinese descent residing in countries outside of China who participated in a cross-sectional online survey between April 22 and May 9, 2020. This study utilized a structural equation model (SEM) to evaluate both direct and indirect effects of perceived discrimination on self-rated health (SRH) and to assess the mediating roles of psychological distress (namely, anxiety and depression) and social support from family and friends.

RESULTS

This online sample comprised predominantly young adults and those of relatively high socioeconomic status. This study confirmed the total and direct effect of recently perceived discrimination on SRH and found the indirect effect was mainly mediated by depression. Mediating roles of anxiety and social support on the discrimination-health relationship were found insignificant in this SEM.

CONCLUSIONS

Our findings suggest discrimination negatively affected the well-being of the Chinese diaspora, and depression acted as a major mediator between the discrimination-health relationship. Therefore, interventions for reducing discrimination to preserve the well-being of the Chinese diaspora are necessary. Prompt intervention to address depression may partially relieve the disease burden caused by the surge of discrimination.

Differences in Health Characteristics of Geographic Subgroups of Arab Americans in a Northern California Health Plan

INTRODUCTION

Arab Americans are a diverse ethnic group originating from a large geographic area in the Middle East and North Africa (MENA). We aim to characterize differences in health between Arab Americans from different geographic subgroups within MENA.

METHODS

We used cross-sectional electronic health record (EHR) data for a subset of 4913 Arab Americans aged 20-84 in a 2016 Northern California health plan study cohort who could be assigned to one of 4 geographic subgroups (Gulf, African, Levant, and Other) based on EHR ethnicity data. We calculated age-adjusted prevalence estimates for men and women and used generalized linear models to compare Gulf, African, and Other subgroups to Levant Arabs on risk factors (obesity and smoking), chronic conditions (diabetes, hypertension, hyperlipidemia, and asthma), and mental health (depression and anxiety).

RESULTS

Among women, prevalence of smoking was lower among Gulf, African, and Other Arabs than Levant Arabs. Among men, prevalence of obesity, diabetes, and hyperlipidemia was lower among Gulf, African, and Other Arabs than Levant Arabs, while prevalence of depression was higher for these subgroups than Levant Arabs.

DISCUSSION

We found substantial differences in health characteristics across Arab Americans from different geographic subgroups. Our results suggest that more detailed race and ethnicity information should be collected on Arab Americans to better understand their diverse health risks.

Racial Non-equivalence of Socioeconomic Status and Self-rated Health among African Americans and Whites

Racial health inequities are not fully explained by socioeconomic status (SES) measures like education, income and wealth. The largest inequities are observed among African American and white college graduates suggesting that African Americans do not receive the same health benefits of education. African Americans do not receive the same income and wealth returns of college education as their white counterparts indicating a racial non-equivalence of SES that may affect health inequities. The aim of this study is to determine whether racial non-equivalence of SES mediates race inequities in self-rated health by education and sex. Using data from the 2007-2016 National Health and Nutrition Examination Survey in the United States, the mediation of the associations between race and self-rated health through household income ≥400% federal poverty line, homeownership, and investment income were assessed among college graduates and non-college graduates by sex. Indirect associations were observed among college graduate women (odds = 0.08, standard error (s.e.) = 0.03), and non-college graduate men (odds = 0.14, s.e. = 0.02) and women (odds = 0.06, s.e. = 0.02). Direct associations between race and self-rated health remained after accounting for household income and wealth indicators suggesting that race differences in income and wealth partially mediate racial inequities in self-rated health. This study demonstrates that the racial non-equivalence of SES has implications for health inequities, but the magnitude of indirect associations varied by sex. Other factors like discrimination, health pessimism and segregation should be considered in light of the racial non-equivalence of SES and racial inequities in self-rated health.

Health Literacy and Self-Rated Health among Homeless Adults

Poor health literacy reduces the efficacy of behavior change interventions, hampers management of health conditions, and attenuates understanding of the prevention and treatment of diseases. Poor health literacy has also been linked to fair/poor self-rated health in domiciled samples; however, there is a paucity of studies on the relation amongst homeless adults, who bear a disproportionate burden of disease and disability and require high level of care and access to health services. Here, we examined the association between health literacy and self-rated health among a convenience sample of homeless adults. Participants were recruited from six homeless-serving agencies in Oklahoma City (N = 575; 63% men, Mage = 43.6±12.3). Logistic regression was used to assess the association between health literacy (confidence completing medical forms: extremely/quite a bit vs somewhat/little bit/not at all) and self-rated health (poor/fair vs good/very good/excellent) controlling for age, subjective social status, education, race, sex, income, health insurance, employment, social security recipient status, diabetes diagnosis, high blood pressure diagnosis, and high cholesterol diagnosis. In the adjusted model, health literate homeless individuals had greater odds of endorsing good/very good/excellent self-rated health compared to those somewhat/a little bit/not at all confident completing medical forms (AOR = 2.02, [CI95% = 1.35-3.02]). Interventions targeted at adjusting reading level and comprehensibility of health information are needed for homeless individuals with poor/limited health literacy, which may ultimately impact their self-rated health. Shelters and homeless-serving agencies could host classes focused on practical skills for enhancing health literacy and/or provide navigation services.

Characterizing Discrimination Experiences by Race among Homeless Adults

Objectives: Among domiciled samples, racial discrimination is a known stressor linked with poorer quality of life. However, homeless adults may be particularly vulnerable to discrimination due to multiple factors beyond race. In this study, we characterized perceived discrimination and its reported impact on quality of life in a sample of adults who were homeless. Methods: Homeless adults recruited from Oklahoma City self-reported their socio-demographics, past discrimination experiences, and their impact on quality of life via the MacArthur Major Experiences of Discrimination Questionnaire. Descriptive statistics and frequencies were used to characterize perceived discrimination experiences and impact. Racial differences were examined using ANO- VAs/Kruskal-Wallis tests and chi-square tests. Results: Discrimination experiences attributed to homelessness were common and consistent between the races. Black adults perceived significantly more lifetime discrimination experiences than white adults, and attributed the majority to race. Relative to Whites and American Indians, black adults were more likely to endorse links between discrimination and having a harder life. Conclusions: Results suggest that black homeless adults may represent the most vulnerable racial subgroup for hardships in life as a conse- quence of perceived discrimination among homeless adults.

The buffering effect of social support on the relationship between discrimination and psychological distress among church-going African-American adults

Discrimination is a pervasive stressor among African-American adults. Social support is an important protective factor for psychological distress, especially among minority populations. Although a number of studies have examined social support in relation to discrimination, little research has examined how social support may serve as an important protective factor against both physical and psychological symptoms related to overall psychological distress within this group. The current study examined social support as a moderator of the relationship between discrimination and overall psychological distress as measured by the Brief Symptom Inventory among a community sample of 122 African-American church-going adults. Results indicated that social support buffered the associations of discrimination and overall psychological distress (p < 0.0001) in expected directions. Findings highlight the importance of cultivating strong social relationships to attenuate the effects of this social determinant on mental health disparities among this group.

Perceived discrimination is associated with the inflammatory response to acute laboratory stress in women at risk for cardiovascular disease

Cardiovascular disease (CVD) is the leading cause of death in the United States and exacts a disproportionate toll on minorities. Growing evidence demonstrates that perceived discrimination is a significant contributing factor to psychological distress, chronic low-grade inflammation, and cardiovascular health. However, little is known regarding the extent to which perceived discrimination contributes to the inflammatory response to acute stress. Therefore, the purpose of this study was to examine the influence of perceived discrimination on the inflammatory response to a laboratory acute stress paradigm in women at risk for CVD. A cross-sectional sample of 99 postmenopausal women (50 African American and 49 non-Hispanic White) (mean age 60.2 years) with at least two risk factors for CVD underwent the Trier Social Stress Test (TSST). Subjects completed the Detroit Area Study Discrimination Scale (DAS-DS) Everyday Discrimination subscale and provided blood and saliva samples prior to the TSST and every 15 min up to 90 min post-TSST to measure a pro-inflammatory cytokine, interleukin-6 (IL-6). Perceived discrimination was significantly associated with the salivary IL-6 response to the TSST (b = 0.49, SE = 0.13, p = <0.001) controlling for age, race, marital status, household income, BMI, statin use, childhood maltreatment, depressive symptoms, and subjective social status. Women who reported higher levels of perceived discrimination had higher levels of salivary IL-6 at baseline and following the TSST as compared to women who reported lower levels of perceived discrimination. Results suggest that higher levels of perceived discrimination, regardless of race and socioeconomic status, may heighten levels of inflammation, prior to and following an acute stress exposure. The circulating Il-6 response was associated with BMI only and did not correlate with salivary IL-6. These data suggest that perceived discrimination may contribute to the salivary-IL-6 acute stress response. However, more research is needed to help clarify the complex relationships among stress and salivary proinflammatory cytokines.

HPV Awareness, Knowledge and Vaccination Attitudes among Church-going African-American Women

OBJECTIVES

The purpose of this exploratory study was to improve understanding of the sociodemographic correlates of human papillomavirus (HPV) awareness, knowledge, and vaccination attitudes in a convenience sample of church-going, African-American women and how knowledge about HPV-related cancers relates to vaccination attitudes for girls and boys.

METHODS

Participants (N = 308) answered survey questions about HPV awareness, knowledge, and vaccination attitudes. Associations between variables were assessed using Bonferroni-adjusted chi-square tests and regression analyses.

RESULTS

Younger age was associated with having heard of HPV and willingness to vaccinate a daughter or son in covariate-adjusted analyses. Younger age and greater education were associated with knowledge that HPV causes cervical cancer. A positive association existed between willingness to vaccinate a daughter or son based on knowledge of the number of cancers associated with HPV. Knowledge that HPV was related to non-cervical cancers was significantly associated with greater willingness to vaccinate sons.

CONCLUSIONS

Knowledge that HPV causes multiple cancers is important to willingness to vaccinate a child. Education campaigns should emphasize that HPV is also related to non-cervical cancers. African-American women of older age and less education might benefit from church-based HPV educational campaigns.

Validation of theoretical pathway between discrimination, diabetes self-care and glycemic control

AIMS

This study examined the mechanisms through which discrimination influences diabetes self-care and glycemic control in patients with diabetes by using structured equation modeling.

METHODS

615 patients were recruited from two adult primary care clinics in the southeastern United States. Measures were based on a theoretical model and included perceived discrimination, social support, social cohesion, and perceived stress. Structured equation modeling examined the relationship with diabetes self-care and glycemic control.

RESULTS

The final model (chi2(211)=328.82, p<0.0001, R(2)=0.99, RMSEA=0.03 and CFI=0.98) shows that higher stress is directly significantly related to a decreased self-care (r=-0.59, p <0.001) and increased HbA1c (r=0.27, p<0.05). There was no significant direct association between discrimination, social support or social cohesion, and glycemic control or self-care. There was, however, a direct significant association between increased discrimination (r=0.46, p<0.001), decreased social support (r=-0.34, p<0.001), increased social cohesion (r=0.14, p<0.05) and increased stress.

CONCLUSIONS

These results support the hypothesized pathway of discrimination on health outcomes, showing both a direct and indirect influence through stress on HbA1c in adults with diabetes. Understanding the pathways through which discrimination influences diabetes outcomes is important for providing more comprehensive and effective care. These results suggest future interventions targeting patients with diabetes should take discrimination-induced stress into account.

Stress eating and sleep disturbance as mediators in the relationship between depression and obesity in low-income, minority women

The purpose of this study was to explore potential mediators of the relationship between depression and obesity in a sample of low-income, minority women. Data were extracted from a sample of 535 women enrolled in a weight loss intervention for the prevention of type 2 diabetes. Using a non-parametric bootstrapping procedure, the potential mediation effects of stress eating and sleep disturbance on the relationship between depression and obesity were tested. Results of a single mediation model indicated that depressive symptomatology was significantly associated with obesity (β=0.800, SE=0.290, p=0.006), and that stress eating (β=0.166, 95% CI [0.046, 0.328]) and sleep disturbance (β=1.032, 95% CI [0.612, 1.427]) were significant independent mediators of this relationship. Sleep disturbance remained a significant mediator in a combined mediation model (β=1.009, 95% CI [0.653, 1.399]). Findings add to the growing literature on the psychosocial factors implicated in the link between depression and obesity, particularly among disadvantaged populations. Future longitudinal research should aim to establish causal pathways between obesity, stress eating, sleep disturbance, and depression.

Psychosocial Mechanisms Linking the Social Environment to Mental Health in African Americans

Resource-poor social environments predict poor health, but the mechanisms and processes linking the social environment to psychological health and well-being remain unclear. This study explored psychosocial mediators of the association between the social environment and mental health in African American adults. African American men and women (n = 1467) completed questionnaires on the social environment, psychosocial factors (stress, depressive symptoms, and racial discrimination), and mental health. Multiple-mediator models were used to assess direct and indirect effects of the social environment on mental health. Low social status in the community (p < .001) and U.S. (p < .001) and low social support (p < .001) were associated with poor mental health. Psychosocial factors significantly jointly mediated the relationship between the social environment and mental health in multiple-mediator models. Low social status and social support were associated with greater perceived stress, depressive symptoms, and perceived racial discrimination, which were associated with poor mental health. Results suggest the relationship between the social environment and mental health is mediated by psychosocial factors and revealed potential mechanisms through which social status and social support influence the mental health of African American men and women. Findings from this study provide insight into the differential effects of stress, depression and discrimination on mental health. Ecological approaches that aim to improve the social environment and psychosocial mediators may enhance health-related quality of life and reduce health disparities in African Americans.

Assessing mediators between discrimination, health behaviours and physical health outcomes: a representative cross-sectional study

PURPOSE

Discrimination is a social determinant of health; however, the pathways linking discrimination to ill-health are under-researched. This study investigated the mediators through which discrimination affects health behaviours and physical health outcomes, as well as assessed whether sex moderated these mechanisms.

METHODS

Data from a representative survey (n = 1023) of undergraduate students enrolled in a Brazilian university in 2012 were used. Structural equation models were applied to assess the following mediation mechanisms--(1) discrimination influences self-rated health and body mass index via anxiety/depression; (2) discrimination affects behaviours (alcohol consumption, problem drinking, smoking, fruit/vegetable consumption, and physical activity) through discomfort associated with discriminatory experiences. The potential of sex to act as an effect-modifying variable was also explored in each of the postulated pathways.

RESULTS

The effect of discrimination on self-rated poor health was totally (100.0%) mediated by anxiety/depression, while body mass index was not correlated with discrimination. Self-reported discrimination was associated with some behaviours via discomfort. Particularly, discomfort partially mediated the positive association between discrimination, leisure time physical activity (43.3%), and fruit/vegetable consumption (52.2%). Sex modified the association between discrimination, discomfort and physical activity in that such mechanism (more discrimination → more discomfort → more physical activity) was statistically significant in the entire sample and among females, but not among males.

CONCLUSIONS

This is one of the first studies to demonstrate that discrimination is associated with physical health outcomes and behaviours via distinct pathways. Future investigations should further explicate the mediational pathways between discrimination and key health outcomes.

HPV awareness, knowledge and attitudes among older African-American women

OBJECTIVE

To assess correlates of human papillomavirus (HPV) awareness, knowledge, and attitudes among older, church-going African-American women.

METHODS

Participants (N = 759), aged 40-80, answered survey questions about HPV awareness, knowledge, and attitudes toward vaccination of adolescent daughters. Associations between participant characteristics and HPV items were assessed using chi-square tests and logistic regression analyses.

RESULTS

Younger age, higher education, a family history of cancer, and less spirituality were each associated with HPV awareness individually, and when considered jointly in a single model (p values <.038). Higher education was related to HPV knowledge (p = .006).

CONCLUSIONS

African-American women of older age, less education, no family history of cancer, and/or higher spirituality might benefit from targeted church-based HPV educational campaigns.

Loneliness and self-rated health among church-attending African Americans

OBJECTIVES

To explore relations between loneliness and self-rated health among African-American adults of diverse ages.

METHODS

Associations between loneliness and self-rated health were investigated using covariate-adjusted linear regression models. Perceived social support was examined as a moderator. The potential indirect effects of stress and/or depressive symptoms were examined using nonparametric bootstrapping procedures.

RESULTS

Greater loneliness was associated with poorer self-rated health (p = .008), and social support did not moderate. Stress and depressive symptoms yielded significant indirect effects in single and multiple mediator models (p values ≤ .05).

CONCLUSIONS

Loneliness may contribute to poorer health among African Americans. Results suggest that greater stress and depressive symptoms might underlie these associations, but longitudinal studies are needed to assess causal relations.

The influence of discrimination on smoking cessation among Latinos

BACKGROUND

Although studies have shown a cross-sectional link between discrimination and smoking, the prospective influence of discrimination on smoking cessation has yet to be evaluated. Thus, the purpose of the current study was to determine the influence of everyday and major discrimination on smoking cessation among Latinos making a quit attempt.

METHODS

Participants were 190 Spanish speaking smokers of Mexican Heritage recruited from the Houston, TX metropolitan area who participated in the study between 2009 and 2012. Logistic regression analyses were conducted to evaluate the associations of everyday and major discrimination with smoking abstinence at 26 weeks post-quit.

RESULTS

Most participants reported at least some everyday discrimination (64.4%), and at least one major discrimination event (56%) in their lifetimes. Race/ethnicity/nationality was the most commonly perceived reason for both everyday and major discrimination. Everyday discrimination was not associated with post-quit smoking status. However, experiencing a greater number of major discrimination events was associated with a reduced likelihood of achieving 7-day point prevalence smoking abstinence, OR=.51, p=.004, and continuous smoking abstinence, OR=.29, p=.018, at 26 weeks post-quit.

CONCLUSIONS

Findings highlight the high frequency of exposure to discrimination among Latinos, and demonstrate the negative impact of major discrimination events on a smoking cessation attempt. Efforts are needed to attenuate the detrimental effects of major discrimination events on smoking cessation outcomes.
