Race and other sociodemographic categories are differentially linked to multiple dimensions of interpersonal-level discrimination: Implications for intersectional, health research

The Influence of Contested Racial Identity and Perceived Everyday Discrimination Exposure on Body Mass Index in US Adults

Contested racial identity-the discrepancy between one's self-identified race and socially assigned race-is a social determinant of health and may contribute to overweight and obesity. Obesity is associated with a host of short- and long-term health conditions, including cardiovascular disease, a leading cause of death. Individuals racialized as Black, Hispanic, and Latino are at the greatest risk of obesity. Previous research indicates that experiencing interpersonal discrimination is associated with higher body mass index (BMI) in adults, and individuals with a contested racial identity are disproportionately exposed to interpersonal discrimination. However, the association between BMI and contested racial identity is unknown. This cross-sectional study measured the relationship between contested racial identity and perceived everyday discrimination on BMI in a nationally representative sample of US adults. Contested racial identity was measured with a binary variable indicating agreement between participants' self-identified race and socially assigned race. Weighted unadjusted and adjusted multiple linear regression models quantified the associations between BMI and contested racial identity with and without the mean discrimination score. Covariates included nativity status, income, education, racial identity salience, gender, and age. Among 1689 participants, 18.3% had a contested racial identity. Contested identity was associated with significantly higher BMI (β = 1.01, 95% CI = 0.06, 1.92), but the relationship was attenuated when adjusting for interpersonal discrimination, suggesting that individuals with contested identity may face a greater risk of obesity due to their disproportionately high exposure to interpersonal racial discrimination. Further research is needed to elucidate the impact of racism on BMI and obesity risk.

Consideration of Demographic Variables in Behavioral Interventions Pertaining to Children With Hearing Loss: A Systematic Review

PURPOSE

Equitable representation of children with hearing loss who are members of marginalized or minority groups in behavioral intervention studies enhances inclusivity in the scientific process and generalizability of results. The goal of this systematic review was to ascertain the percentage of studies conducted in the United States in the past 2 decades that reported relevant demographic variables.

METHOD

Studies were searched across eight databases and clinical trial registries in October 2022. Variations of the following search strings were used to retrieve peer-reviewed published studies and unpublished clinical trials: children, hearing loss, and intervention.

RESULTS

Thirty-nine intervention studies met the inclusion criteria. The selected studies were reviewed and coded for the following demographic variables: area and type of intervention, participant age, hearing technology data, sample size, gender, race/skin color and ethnicity, primary/home language(s), additional disabilities, parental education, family income, and parental occupation. Results revealed that many demographic variables were remarkably underreported, with parental education, family income, and parental occupation variables being the least reported data.

CONCLUSIONS

Demographic data can be an important tool for changing disparities related to intervention outcomes. This systematic review suggests that inclusive research practices should be extended to low-literacy or low-economic resources, non-White, and non-English-speaking groups. Inclusion practices coupled with sufficient sample sizes will ultimately aid in identifying hearing health disparities.

Racial Discrimination, Religious Coping, and Cardiovascular Disease Risk Among African American Women and Men

OBJECTIVE

This cross-sectional study examined whether religious coping buffered the associations between racial discrimination and several modifiable cardiovascular disease (CVD) risk factors-systolic and diastolic blood pressure (BP), glycated hemoglobin (HbA1c), body mass index (BMI), and cholesterol-in a sample of African American women and men.

METHODS

Participant data were taken from the Healthy Aging in Neighborhoods of Diversity Across the Life Span study (N = 815; 55.2% women; 30-64 years old). Racial discrimination and religious coping were self-reported. CVD risk factors were clinically assessed.

RESULTS

In sex-stratified hierarchical regression analyses adjusted for age, socioeconomic status, and medication use, findings revealed several significant interactive associations and opposite effects by sex. Among men who experienced racial discrimination, religious coping was negatively related to systolic BP and HbA1c. However, in men reporting no prior discrimination, religious coping was positively related to most risk factors. Among women who had experienced racial discrimination, greater religious coping was associated with higher HbA1c and BMI. The lowest levels of CVD risk were observed among women who seldom used religious coping but experienced discrimination.

CONCLUSION

Religious coping might mitigate the effects of racial discrimination on CVD risk for African American men but not women. Additional work is needed to understand whether reinforcing these coping strategies only benefits those who have experienced discrimination. It is also possible that religion may not buffer the effects of other psychosocial stressors linked with elevated CVD risk.

Adding Insult to Injury: Everyday Discrimination Moderates Stressor-Related Negative Affect

Studies examining the effects of discrimination on emotional well-being have often overlooked (a) differential effects of both everyday and lifetime discrimination and (b) how both types of discrimination may exacerbate stressor-related affect-even when daily stressors are unrelated to discrimination. The current study examined the effects of daily stressors not attributed to discrimination (i.e., nondiscrimination-related daily stressors) on daily negative and positive affect in the presence of either form of discrimination (everyday and lifetime). Participants who completed the second wave of the Survey of Midlife Development in the US (MIDUS-II) and the National Study of Daily Experiences (NSDE-II) answered questionnaires about everyday and lifetime discrimination. Later, they completed daily phone interviews across 8 consecutive days, asking about the nondiscrimination-related daily stressors and the positive and negative affect they had experienced that day. Multilevel model analyses revealed that everyday discrimination was associated with decreased daily positive affect and lifetime discrimination was associated with increased daily negative affect. Moreover, higher frequency of everyday discrimination exacerbated the within-person effects of nondiscriminatory daily stressors on negative affect. Results underscore the importance of considering both independent and synergistic effects of discrimination on daily emotional well-being.

Stigmatising and Racialising COVID-19: Asian People's Experience in New Zealand

The Asian community - the second largest non-European ethnic community in New Zealand - plays an important role in combatting the COVID-19 pandemic, evidenced by their active advocation for border control and mass masking. Despite the long history of racial discrimination against the Asian population, the Asian community has experienced certain degrees of racial discrimination associated with the stigmatisation as the cause of the COVID-19 outbreak in New Zealand. Based on data from a quantitative online survey with 402 valid responses within the Asian communities across New Zealand and the in-depth interviews with 19 Asian people in Auckland, New Zealand, this paper will illustrate Asian people's experience of racial discrimination and stigmatisation during the pandemic in the country. The survey shows that since the outbreak of COVID-19, under a quarter of the participants reported experiencing discrimination, and a third reported knowing an immediate contact who had experienced discrimination. However, when looking beyond their immediate social circle, an even higher proportion reported noticing racism and stigmatisation through the traditional or social media due to COVID-19. Major variations of the degree of racial discrimination experienced are determined by three demographic variables: ethnicity, age, and region. The in-depth interviews largely echoed the survey findings and highlighted a strong correlation between the perceived racial discrimination among the local Asian community and the stigmatisation associated with COVID-19. These findings are important for improving the way we manage future pandemics and other disasters within the context of the UN Sendai Framework for Disaster Risk Reduction.

A multivariable model of barriers to COVID-19 vaccination: Using cross sectional data from a nationally distributed survey in the United States

OBJECTIVE

Discrimination has had longstanding effects on mental and physiological health, which became more evident and synergized during the COVID-19 pandemic. The role of discrimination on vaccination for COVID-19 during the pandemic, however, is not well understood. As such, we examined the relationship of everyday discrimination on COVID-19 vaccination.

METHODS

Using a multivariate logistic regression on data collected from a nationally distributed survey in the United States (US), we examined the relationship of discrimination measured by the Everyday Discrimination Scale on self-reported COVID-19 vaccination while adjusting for US nativity, as well as sociodemographic (i.e., age; gender; sexual orientation; race, and ethnicity) and socioeconomic (i.e., educational attainment; employment status; household income) factors.

RESULTS

We found that participants reporting monthly to weekly discrimination and multiple times a week to daily discrimination had decreased odds of reporting COVID-19 vaccination (adjusted odds ratio [AOR] = 0.78, 95% confidence interval [CI]:0.68-0.90; and AOR = 0.75, 95% CI = 0.62-0.91, respectively) compared to those that reported no discrimination experienced. Educational attainment of high school equivalent or above, employment as an essential worker, and household-annual income of $50,000 or greater were significant socioeconomic factors. Age, sexual orientation, and race/ethnicity had mixed associations with COVID-19 vaccination.

CONCLUSIONS

Discrimination overall remained a significant barrier to vaccination, while nativity was not significant when accounting for socioeconomic and sociodemographic factors. Discrimination must become a public health priority in addressing disparities in health and access and barriers that may affect preventive behaviors.

A framework to improve retention of Black surgical trainees: A Society of Black Academic Surgeons white paper

Attrition is high among surgical trainees, and six of ten trainees consider leaving their programs, with two ultimately leaving before completion of training. Given known historically and systemically rooted biases, Black surgical trainees are at high risk of attrition during residency training. With only 4.5% of all surgical trainees identifying as Black, underrepresentation among their peers can lend to misclassification of failure to assimilate as clinical incompetence. Furthermore, the disproportionate impact of ongoing socioeconomic crisis (e.g., COVID-19 pandemic, police brutality etc.) on Black trainees and their families confers additional challenges that may exacerbate attrition rates. Thus, attrition is a significant threat to medical workforce diversity and health equity. There is urgent need for surgical programs to develop proactive approaches to address attrition and the threat to the surgical workforce. In this Society of Black Academic Surgeons (SBAS) white paper, we provide a framework that promotes an open and inclusive environment conducive to the retention of Black surgical trainees, and continued progress towards attainment of health equity for racial and ethnic minorities in the United States.

Association of Calpain10 polymorphisms with polycystic ovarian syndrome susceptibility: a systematic review and meta-analysis with trial sequential analysis

Insulin resistance plays an important role in the pathogenesis of polycystic ovarian syndrome (PCOS). Calpain10 (CAPN10) gene was the first identified susceptibility gene for type 2 diabetes mellitus and closely related to insulin sensitivity. A lot of research attention has been attracted on the relationship between CAPN10 polymorphisms and PCOS risk, but they didn't reach a consistent conclusion. We therefore performed this systematic review and meta-analysis to assess the association of CAPN10 common variants with PCOS susceptibility. A total of 21 studies were eligible for inclusion. Meta-analyses were done for 5 variants that had at least two data sources: UCSNP-19, -43, -44, -56 and -63. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated under five genetic models. Subgroup analyses by ethnicity, PCOS diagnostic criteria, and source of controls were conducted. Moreover, false-positive report probability (FPRP) test and trial sequential analysis (TSA) were performed to assess the significant associations. The results showed a possible negative association between UCSNP-19 and PCOS risk (ins/ins vs. del/del + del/ins: OR = 0.84, 95% CI: 0.72-0.98). In subgroup analyses, FPRP test indicated that noteworthy associations were observed in mixed ethnicities for UCSNP-43 (A vs. G: OR = 1.81, 95% CI: 1.17-2.79; AA + AG vs. GG: OR = 2.14, 95% CI: 1.20-3.80) and in Asians for UCSNP-44 (CC vs. TT: OR = 2.07, 95% CI: 1.21-3.51; CC vs. CT + TT: OR = 2.19, 95% CI: 1.31-3.69), but TSA plots showed that the accumulated sample sizes of these associations were insufficient to draw firm conclusions. In summary, our study suggested that UCSNP-19, UCSNP-43, and UCSNP-44 in CAPN10 gene may be involved in PCOS susceptibility. These findings warrant further studies.

How Discrimination Gets Under the Skin: Biological Determinants of Discrimination Associated With Dysregulation of the Brain-Gut Microbiome System and Psychological Symptoms

BACKGROUND

Discrimination is associated with negative health outcomes as mediated in part by chronic stress, but a full understanding of the biological pathways is lacking. Here we investigate the effects of discrimination involved in dysregulating the brain-gut microbiome (BGM) system.

METHODS

A total of 154 participants underwent brain magnetic resonance imaging to measure functional connectivity. Fecal samples were obtained for 16S ribosomal RNA profiling and fecal metabolites and serum for inflammatory markers, along with questionnaires. The Everyday Discrimination Scale was administered to measure chronic and routine experiences of unfair treatment. A sparse partial least squares-discriminant analysis was conducted to predict BGM alterations as a function of discrimination, controlling for sex, age, body mass index, and diet. Associations between discrimination-related BGM alterations and psychological variables were assessed using a tripartite analysis.

RESULTS

Discrimination was associated with anxiety, depression, and visceral sensitivity. Discrimination was associated with alterations of brain networks related to emotion, cognition and self-perception, and structural and functional changes in the gut microbiome. BGM discrimination-related associations varied by race/ethnicity. Among Black and Hispanic individuals, discrimination led to brain network changes consistent with psychological coping and increased systemic inflammation. For White individuals, discrimination was related to anxiety but not inflammation, while for Asian individuals, the patterns suggest possible somatization and behavioral (e.g., dietary) responses to discrimination.

CONCLUSIONS

Discrimination is attributed to changes in the BGM system more skewed toward inflammation, threat response, emotional arousal, and psychological symptoms. By integrating diverse lines of research, our results demonstrate evidence that may explain how discrimination contributes to health inequalities.

Intersectional vulnerability in the relationship between discrimination and inflammatory gene expression

Addressing social disparities in health and well-being requires understanding how the effects of discrimination become biologically embedded, and how embedding processes might vary across different demographic contexts. Emerging research suggests that a threat-related gene expression response may contribute to social disparities in health. We tested a contextual vulnerability model of discrimination embedding using an empirical intersectionality (interaction discovery) analysis of pro-inflammatory gene expression in a national sample of non-institutionalized, English-speaking adults with RNA biomarker data (n = 543). At the time of data collection, the average age of participants was 55 years (SD = 13.26) and approximately half identified as female (50.46%). Most participants identified as White (∼73%) and had some college experience (∼60%). Results showed significant variation in the strength of association between daily discrimination and inflammatory gene expression by race and sex (b = -0.022; 95% CI:-0.038,-0.005, p = .009) with the estimated marginal association larger for racially-minoritized males (b = 0.007; 95% CI:-0.003,0.017, p = .163), compared to White males (b = -0.006; 95% CI:-0.013,0.001, p = .076). This study indicates that the link between daily discrimination and inflammatory gene expression may vary by sociodemographic characteristics. To improve initiatives and policies aimed at ameliorating disparities within populations, greater attention is needed to understand how interlocking systems of inequalities contribute to physiological health.

Racial Disparities in Respectful Maternity Care During Pregnancy and Birth After Cesarean in Rural United States

OBJECTIVE

To describe the experiences of pregnancy and birth after cesarean of women who live in rural areas of the United States, including access to vaginal birth after cesarean (VBAC), type of maternity care provider, travel times, autonomy in decision making, and respectful maternity care.

DESIGN

Retrospective observational study.

SETTING

Online questionnaire of women who gave birth in the United States.

PARTICIPANTS

Women (N = 1,711) with histories of cesarean and subsequent births within 5 years of participating.

METHODS

We calculated descriptive and bivariate statistics by identified areas of residence and stratified measures of autonomy and respectful maternity care by self-identification as a member of a racialized group. We applied qualitative descriptive analysis to responses to an open-ended survey question.

RESULTS

A total of 299 (17.5%) participants identified their areas of residence as rural. Similar percentages of rural and metropolitan participants were able to plan VBAC (p = .88). More rural participants than metropolitan participants reported travel times of more than 60 minutes to give birth (p < .001), and fewer had obstetricians (p = .002) or doulas (p = .03). Rural participants from racialized groups experienced significantly less respectful maternity care than White, non-Hispanic rural participants and all metropolitan participants (p = .04). Qualitative data illustrating the main findings are included.

CONCLUSIONS

Our findings highlight challenges faced by rural residents accessing VBAC and help explain why rates of VBAC in rural areas remain low. We suggest a range of clinical and policy strategies to improve access to VBAC in rural areas and to improve the quality of maternity care for racialized women who live in rural areas.

Inequities in quality perinatal care in the United States during pregnancy and birth after cesarean

OBJECTIVE

High-quality, respectful maternity care has been identified as an important birth process and outcome. However, there are very few studies about experiences of care during a pregnancy and birth after a prior cesarean in the U.S. We describe quantitative findings related to quality of maternity care from a mixed methods study examining the experience of considering or seeking a vaginal birth after cesarean (VBAC) in the U.S.

METHODS

Individuals with a history of cesarean and recent (≤ 5 years) subsequent birth were recruited through social media groups to complete an online questionnaire that included sociodemographic information, birth history, and validated measures of respectful maternity care (Mothers on Respect Index; MORi) and autonomy in maternity care (Mother's Autonomy in Decision Making Scale; MADM).

RESULTS

Participants (N = 1711) representing all 50 states completed the questionnaire; 87% planned a vaginal birth after cesarean. The most socially-disadvantaged participants (those less educated, living in a low-income household, with Medicaid insurance, and those participants who identified as a racial or ethnic minority) and participants who had an obstetrician as their primary provider, a male provider, and those who did not have a doula were significantly overrepresented in the group who reported lower quality maternity care. In regression analyses, individuals identified as Black, Indigenous, and People of Color (BIPOC) were less likely to experience autonomy and respect compared to white participants. Participants with a midwife provider were more than 3.5 times more likely to experience high quality maternity care compared to those with an obstetrician.

CONCLUSION

Findings highlight inequities in the quality of maternal and newborn care received by birthing people with marginalized identities in the U.S. They also indicate the importance of increasing access to midwifery care as a strategy for reducing inequalities in care and associated poor outcomes.
