Differential effect of social mobility on tooth loss by race in adulthood: 1982 Pelotas Birth Cohort Study

OBJECTIVES

To examine the association between social mobility and tooth loss in adults from the 1982 Pelotas Birth Cohort Study and whether race modifies this association.

METHODS

The Oral Health Study used data from 541 individuals who were followed up to 31 years of age. Social mobility, composed of the participants' socioeconomic position (SEP) at birth and at age 30, was categorized as never poor, upwardly mobile, downwardly mobile and always poor. The outcome was the prevalence of at least one tooth lost due to dental caries when the participants were examined at 31 years of age. The effect modifier was race (Black/Brown versus white people). Log-binomial regression models were used to estimate crude and sex-adjusted prevalence ratios (PR) and to determine whether the association varied with race. Statistical interactions were tested using an additive scale.

RESULTS

The prevalence of any tooth loss was 50.8% (n = 274). In social mobility groups, the prevalence of at least one tooth lost in the never-poor group was about 31% points higher for Black/Brown (68.2%) than for white people (37.4%). Antagonistic findings were found for the interaction between race and social mobility (Sinergy Index = 0.48; 95% CI 0.24, 0.99; and relative excess of risk due to the interaction = -1.38; 95% CI -2.34, -0.42), suggesting that the observed joint effect of race and social mobility on tooth loss was lower than the expected sum of these factors. The estimates for Black/Brown people were smaller for those who were always poor during their lives, relative to their white counterparts.

CONCLUSIONS

The findings suggest a higher prevalence of at least one tooth lost among people in the downward mobile SEP group and Black/Brown people. Greater racial inequity was found among Black/Brown people who had never experienced episodes of poverty, with Black/Brown people having a greater prevalence of at least one tooth lost than their white counterparts.

Implementation Science to Achieve Equity in Heart Failure Care: A Scientific Statement From the American Heart Association

Guideline-directed medical therapies and guideline-directed nonpharmacological therapies improve quality of life and survival in patients with heart failure (HF), but eligible patients, particularly women and individuals from underrepresented racial and ethnic groups, are often not treated with these therapies. Implementation science uses evidence-based theories and frameworks to identify strategies that facilitate uptake of evidence to improve health. In this scientific statement, we provide an overview of implementation trials in HF, assess their use of conceptual frameworks and health equity principles, and provide pragmatic guidance for equity in HF. Overall, behavioral nudges, multidisciplinary care, and digital health strategies increased uptake of therapies in HF effectively but did not include equity goals. Few HF studies focused on achieving equity in HF by engaging stakeholders, quantifying barriers and facilitators to HF therapies, developing strategies for equity informed by theory or frameworks, evaluating implementation measures for equity, and titrating strategies for equity. Among these HF equity studies, feasibility was established in using various educational strategies to promote organizational change and equitable care. A couple include ongoing randomized controlled pragmatic trials for HF equity. There is great need for additional HF implementation trials designed to promote delivery of equitable guideline-directed therapy.

Comparison of patient background between a real-world North American cohort and the Göteborg-2 trial

OBJECTIVES

To analyze the generalizability of the Göteborg-2 findings to a North American cohort.

METHODS

We replicated the Göteborg-2 inclusion criteria in our Henry Ford Health (HFH) cohort, by identifying all patients 50-60 years old who had a PSA test from 2013 to 2018. The first PSA within the study period was considered PSA at entry, and included in the analysis. Chi-square test was used to compare categorical variables between the Göteborg-2 and HFH cohort, with a particular focus on Black men, who were also analyzed separately.

RESULTS

The HFH patients included in the cohort were 49 456, of which 8562 were Black. In patients within the entire HFH cohort, HFH Black cohort, Göteborg Reference cohort, and Göteborg Experimental cohort, the rate of PSA ≥3 ng/mL was, respectively, 6.8%, 10.2%, 6.8%, and 6.6%. The rate of biopsy performed was, respectively, 1.8%, 4.1%, 5.8%, and 2.5%. PCa was found in, respectively, 1.4%, 3.0%, 2.3%, and 1.5%; Gleason score 3 + 3 in, respectively, 0.5%, 0.8%, 1.2%, and 0.6%; Gleason score > 3 + 3 in, respectively, 0.9%, 2.2%, 1.1%, and 0.9%.

CONCLUSIONS

Our cohort had a lower biopsy rate and a lower incidence of non-csPCa diagnosis than both Göteborg cohorts, while still maintaining the same incidence of csPCa. This implies that the benefits of reducing non-csPCa diagnosis, as observed in the Experimental Göteborg cohort, are not necessarily replicable in U.S. "real-world practice" patients. Also noteworthy, we had a significantly higher percentage of Black men, who showed more aggressive disease.

Racial disparities among mild stroke survivors: predictors of home discharge from a retrospective analysis

BACKGROUND

Half of all strokes are classified as mild, and most mild stroke survivors are discharged home after their initial hospitalization without any post-acute rehabilitation despite experiencing cognitive, psychosocial, motor, and mobility impairments.

OBJECTIVES

To investigate the demographic and clinical characteristics of mild stroke survivors and their association with discharge location.

METHODS

This is a retrospective analysis of mild stroke survivors from 2015-2023 in an academic medical center. Demographic characteristics, clinical measures, and discharge locations were obtained from the electronic health record. The Social Vulnerability Index was used to measure the community vulnerability. Associations between variables and discharge location were examined using bivariate logistic regression analysis.

RESULTS

There were 2,953 mild stroke survivors included in this study. The majority of participants were White (65.46%), followed by Black (19.40%). Black stroke survivors and individuals with higher social vulnerability had a higher proportion of discharges to skilled nursing facilities (p = 0.001). Black patients and patients with high vulnerability in housing type and transportation were less likely to be discharged home.

CONCLUSIONS

Mild stroke survivors have a high rate of home discharge, potentially because less severe stroke symptoms have a reduced need for intensive care. Racial disparities in discharge location were evident, with Black stroke survivors experiencing higher rates of institutionalized care and lower likelihood of being discharged home compared to White counterparts, emphasizing the importance of addressing these disparities for equitable healthcare delivery and optimal outcomes.

Over-the-Counter (OTC) Hearing Aid Availability across the Spectrum of Human Skin Colors

BACKGROUND

Over-the-counter (OTC) hearing aids were recently approved for sale in the United States. Research has shown that consumers prefer hearing devices that match their skin color because these devices are less noticeable. Colorism is discrimination against individuals with relatively darker skin that manifests in "skin-color" product offerings as products being offered primarily in relatively lighter colors.

METHODS

This study compared images of U.S. Food and Drug Administration (FDA)-registered over-the-counter hearing aids to a range of human skin colors.

RESULTS

Most over-the-counter hearing aids are only offered in relatively lighter beige colors. Few over-the-counter hearing aids are available in darker skin colors.

CONCLUSIONS

These findings may represent structural bias, preventing equitable access to darker skin-color OTC hearing aids for individuals with darker skin.

Racial disparities in low-risk cesarean birth rates across hospitals

BACKGROUND

We compared low-risk cesarean birth rates for Black and White women across hospitals serving increasing proportions of Black women and identified hospitals where Black women had low-risk cesarean rates less than or equal to White women.

METHODS

In this cross-sectional analysis of secondary data from four states, we categorized hospitals by their proportion of Black women giving birth from "low" to "high". We analyzed the odds of low-risk cesarean for Black and White women across hospital categories.

RESULTS

Our sample comprised 493 hospitals and the 65,524 Black and 251,426 White women at low risk for cesarean who birthed in them. The mean low-risk cesarean rate was significantly higher for Black, compared with White, women in the low (20.1% vs. 15.9%) and medium (18.1% vs. 16.9%) hospital categories. In regression models, no hospital structural characteristics were significantly associated with the odds of a Black woman having a low-risk cesarean. For White women, birthing in a hospital serving the highest proportion of Black women was associated with a 21% (95% CI: 1.01-1.44) increase in the odds of having a low-risk cesarean.

DISCUSSION

Black women had higher odds of a low-risk cesarean than White women and were more likely to access care in hospitals with higher low-risk cesarean rates. The existence of hospitals where low-risk cesarean rates for Black women were less than or equal to those of White women was notable, given a predominant focus on hospitals where Black women have poorer outcomes. Efforts to decrease the low-risk cesarean rate should focus on (1) improving intrapartum care for Black women and (2) identifying differentiating organizational factors in hospitals where cesarean birth rates are optimally low and equivalent among racial groups as a basis for system-level policy efforts to improve equity and reduce cesarean birth rates.

Food security status and cardiometabolic health among pregnant women in the United States

Introduction

Pregnant women and their offspring are particularly vulnerable to food insecurity and its adverse effects during critical periods of fetal development. Racially/ethnically minoritized women in the United States (US) who are pregnant are additionally burdened by food insecurity, which may exacerbate cardiovascular health (CVH) disparities. Despite heightened social vulnerability, few studies have employed an intersectional framework, including race and gender, to assess the food insecurity and CVH relationship.

Methods

We used 2012-2018 and 2020 National Health Interview Survey data among US pregnant women aged 18-49 years old (N = 1,999) to assess the prevalence of food insecurity status by race/ethnicity and to investigate household food security status in relation to ideal CVH, using a modified ideal CVH (mICVH) metric. We categorized food security status as "very low/low", "marginal", or "high". To assess mICVH, a summary score of 7 clinical characteristics and health behaviors was dichotomized as yes [(7)] vs. no [<7]. Prevalence ratios (PRs) and 95% confidence intervals (CIs) of associations between food security status and mICVH were estimated using Poisson regression with robust variance. Models were adjusted for age, household income, educational attainment, geographic region, marital status, alcohol consumption, survey year, and race/ethnicity (in overall model).

Results

The mean age ± standard error was 29.0 ± 0.2 years. Among pregnant women, 12.7% reported "very low/low", 10.6% reported "marginal", and 76.7% reported "high" food security. "Very low/low" food security prevalence was higher among NH-Black (16.2%) and Hispanic/Latina (15.2%) pregnant women compared to NH-White (10.3%) and NH-Asian (3.2%) pregnant women. The mICVH prevalence was 11.6% overall and 14.5% for NH-White, 4.1% for NH-Black, 5.0% for Hispanic/Latina, and 26.7% for NH-Asian pregnant women. Among all pregnant women, "very low/low" and "marginal" vs. "high" food security status was associated with a lower prevalence of mICVH {[PRvery low/low = 0.26 (95% CI: 0.08-0.75)]; [PRmarginal = 0.47 (95% CI: 0.23 -0.96)]}.

Conclusion

Household food insecurity was higher among pregnant women in minoritized racial/ethnic groups and was associated with lower mICVH prevalence. Given the higher burden of food insecurity among minoritized racial/ethnic groups, food security may be an important intervention target to help address disparities in poor CVH among pregnant women.

Can stepped collaborative care interventions improve post-traumatic stress disorder symptoms for racial and ethnic minority injury survivors?

Objectives

No large-scale randomized clinical trial investigations have evaluated the potential differential effectiveness of early interventions for post-traumatic stress disorder (PTSD) among injured patients from racial and ethnic minority backgrounds. The current investigation assessed whether a stepped collaborative care intervention trial conducted at 25 level I trauma centers differentially improved PTSD symptoms for racial and ethnic minority injury survivors.

Methods

The investigation was a secondary analysis of a stepped wedge cluster randomized clinical trial. Patients endorsing high levels of distress on the PTSD Checklist (PCL-C) were randomized to enhanced usual care control or intervention conditions. Three hundred and fifty patients of the 635 randomized (55%) were from non-white and/or Hispanic backgrounds. The intervention included care management, cognitive behavioral therapy elements and, psychopharmacology addressing PTSD symptoms. The primary study outcome was PTSD symptoms assessed with the PCL-C at 3, 6, and 12 months postinjury. Mixed model regression analyses compared treatment effects for intervention and control group patients from non-white/Hispanic versus white/non-Hispanic backgrounds.

Results

The investigation attained between 75% and 80% 3-month to 12-month follow-up. The intervention, on average, required 122 min (SD=132 min). Mixed model regression analyses revealed significant changes in PCL-C scores for non-white/Hispanic intervention patients at 6 months (adjusted difference -3.72 (95% CI -7.33 to -0.10) Effect Size =0.25, p<0.05) after the injury event. No significant differences were observed for white/non-Hispanic patients at the 6-month time point (adjusted difference -1.29 (95% CI -4.89 to 2.31) ES=0.10, p=ns).

Conclusion

In this secondary analysis, a brief stepped collaborative care intervention was associated with greater 6-month reductions in PTSD symptoms for non-white/Hispanic patients when compared with white/non-Hispanic patients. If replicated, these findings could serve to inform future American College of Surgeon Committee on Trauma requirements for screening, intervention, and referral for PTSD and comorbidities.

Level of evidence

Level II, secondary analysis of randomized clinical trial data reporting a significant difference.

Evaluating Racial Disparities in Implementation and Monitoring of a Remote Blood Pressure Program in a Pregnant Population-A Retrospective Cohort Study

Background: Whether remote blood pressure (BP) monitoring can decrease racial disparities in BP measurement during pregnancy and the postpartum period remains unclear. This study evaluated whether Black and White patients enrolled in the Connected Maternity Online Monitoring (CMOM) program showed improvements in BP ascertainment and interval. Methods: A retrospective cohort of 3,976 pregnant patients enrolled in CMOM were compared to matched usual care patients between January 2016 and September 2022 using electronic health record data. The primary outcomes were BP ascertainment (number of BP measurements) and BP interval (time between BP measurements) during pregnancy and the postpartum period. The proportion of patients with a hypertensive disorder of pregnancy who checked their BP within 7 days of discharge following delivery was also assessed. Results: Enrollment in CMOM was lower among Black patients than White patients (42.1% vs 54.7%, P<0.0001). Patients in the CMOM group had more BP measurements than patients in the usual care group during pregnancy (rate ratio=1.78, 95% CI 1.74-1.82) and the postpartum period (rate ratio=1.30, 95% CI 1.23-1.37), with significant improvements for both Black and White patients enrolled in CMOM compared to patients in usual care. The CMOM intervention did not result in an improvement in 7-day postpartum adherence to checking BP for Black patients (risk ratio=1.03, 95% CI 0.94-1.11) as it did for White patients (risk ratio=1.09, 95% CI 1.01-1.17). Conclusion: Remote BP monitoring programs are a helpful tool to improve the frequency of BP measurements and shorten intervals between measurements during the prenatal and postpartum periods for all patients. Future evaluation is needed to determine the barriers to offering the program to and enrolling Black patients.

Under-Diagnosis of Dementia with Lewy Bodies in Individuals Racialized as Black: Hypotheses Regarding Potential Contributors

Dementia with Lewy bodies (DLB) is one of the most common degenerative dementias after Alzheimer's disease (AD) dementia. DLB is under-diagnosed across populations but may be particularly missed in older Black adults. The object of this review was to examine key features of DLB and potential associations with race in order to hypothesize why DLB may be under-diagnosed in Black adults in the U.S. In terms of dementia, symptoms associated with high rates of co-pathology (e.g., AD, vascular disease) in older Black adults may obscure the clinical picture that might suggest Lewy body pathology. Research also suggests that clinicians may be predisposed to give AD dementia diagnoses to Black adults, potentially missing contributions of Lewy body pathology. Hallucinations in Black adults may be misattributed to AD or primary psychiatric disease rather than Lewy body pathology. Research on the prevalence of REM sleep behavior in diverse populations is lacking, but REM sleep behavior disorder could be under-diagnosed in Black adults due to sleep patterns or reporting by caregivers who are not bed partners. Recognition of parkinsonism could be reduced in Black adults due to clinician biases, cultural effects on self-report, and potentially underlying differences in the frequency of parkinsonism. These considerations are superimposed on structural and systemic contributions to health (e.g., socioeconomic status, education, structural racism) and individual-level social exposures (e.g., social interactions, discrimination). Improving DLB recognition in Black adults will require research to investigate reasons for diagnostic disparities and education to increase identification of core symptoms in this population.

Racial inequality in health care of adults hospitalized with COVID-19

The objective was to analyze the association of race/skin color in health care, in adults hospitalized with severe acute respiratory syndrome (SARS)/COVID-19, between March 2020 and September 2022, with Brazil as the unit of analysis. This is a cross-sectional study that used the Influenza Epidemiological Surveillance Information System (SIVEP-Gripe) database and had a population composed of adults (≥ 18 years) and the final classification was SARS by COVID-19 or unspecified SARS. The direct effect of skin color on in-hospital mortality was estimated through logistic regression adjusted for age, gender, schooling level, health care system and period, stratified by vaccination status. This same model was also used to assess the effect of skin color on the variables related to access to health care services: intensive care unit (ICU), tomography, chest X-ray and ventilatory support. The results show that black, brown and indigenous people died more, regardless the schooling level and number of comorbidities, with 23%, 32% and 80% higher chances of death, respectively, when submitted to ventilatory support. Racial differences were observed in the use of health care services and in outcomes of death from COVID-19 or unspecified SARS, in which ethnic minorities had higher in-hospital mortality and lower use of hospital resources. These results suggest that black and indigenous populations have severe disadvantages compared to the white population, facing barriers to access health care services in the context of the COVID-19 pandemic.

Inequities in Definitive Treatment for Localized Prostate Cancer Among Those With Clinically Significant Mental Health Disorders

INTRODUCTION

Patients with mental health disorders are at risk for receiving inequitable cancer treatment, likely resulting from various structural, social, and health-related factors. This study aims to assess the relationship between mental health disorders and the use of definitive treatment in a population-based cohort of those with localized, clinically significant prostate cancer.

METHODS

We conducted a cohort study analysis in SEER (Surveillance, Epidemiology, and End Results)-Medicare (2004-2015). History of a mental health disorder was defined as presence of specific ICD (International Classification of Diseases)-9 or ICD-10 diagnostic codes in the 2 years preceding cancer diagnosis. Descriptive statistics were performed using Wilcoxon rank-sum and χ2 testing. Multivariable logistic regression was used to evaluate the relationship between mental health disorders and definitive treatment utilization (defined as surgery or radiation).

RESULTS

Of 101,042 individuals with prostate cancer, 7,945 (7.8%) had a diagnosis of a mental health disorder. They were more likely to be unpartnered, have a lower socioeconomic status, and less likely to receive definitive treatment (61.8% vs 68.2%, P < .001). Definitive treatment rates were >66%, 62.8%, 60.3%, 58.2%, 54.3%, and 48.1% for post-traumatic stress disorder, depressive disorder, bipolar disorder, anxiety disorder, substance abuse disorder, and schizophrenia, respectively. After adjusting for age, race and ethnicity, marital status and socioeconomic status, history of a mental health disorder was associated with decreased odds of receiving definitive treatment (OR 0.74, 95% CI 0.66-0.83).

CONCLUSIONS

Individuals with mental health disorders and prostate cancer represent a vulnerable population; careful attention to clinical and social needs is required to support appropriate use of beneficial treatments.

Historical Redlining, Socioeconomic Distress, and Risk of Heart Failure Among Medicare Beneficiaries

BACKGROUND

The association of historical redlining policies, a marker of structural racism, with contemporary heart failure (HF) risk among White and Black individuals is not well established.

METHODS

We aimed to evaluate the association of redlining with the risk of HF among White and Black Medicare beneficiaries. Zip code-level redlining was determined by the proportion of historically redlined areas using the Mapping Inequality Project within each zip code. The association between higher zip code redlining proportion (quartile 4 versus quartiles 1-3) and HF risk were assessed separately among White and Black Medicare beneficiaries using generalized linear mixed models adjusted for potential confounders, including measures of the zip code-level Social Deprivation Index.

RESULTS

A total of 2 388 955 Medicare beneficiaries (Black n=801 452; White n=1 587 503; mean age, 71 years; men, 44.6%) were included. Among Black beneficiaries, living in zip codes with higher redlining proportion (quartile 4 versus quartiles 1-3) was associated with increased risk of HF after adjusting for age, sex, and comorbidities (risk ratio, 1.08 [95% CI, 1.04-1.12]; P<0.001). This association remained significant after further adjustment for area-level Social Deprivation Index (risk ratio, 1.04 [95% CI, 1.002-1.08]; P=0.04). A significant interaction was observed between redlining proportion and Social Deprivation Index (Pinteraction<0.01) such that higher redlining proportion was significantly associated with HF risk only among socioeconomically distressed regions (above the median Social Deprivation Index). Among White beneficiaries, redlining was associated with a lower risk of HF after adjustment for age, sex, and comorbidities (risk ratio, 0.94 [95% CI, 0.89-0.99]; P=0.02).

CONCLUSIONS

Historical redlining is associated with an increased risk of HF among Black patients. Contemporary zip code-level social determinants of health modify the relationship between redlining and HF risk, with the strongest relationship between redlining and HF observed in the most socioeconomically disadvantaged communities.

Differences in food consumption of the Brazilian population by race/skin color in 2017-2018

OBJECTIVE

To evaluate food consumption in Brazil by race/skin color of the population.

METHODS

Food consumption data from the Pesquisa de Orçamentos Familiares (POF - Household Budget Survey) 2017-2018 were analyzed. Food and culinary preparations were grouped into 31 items, composing three main groups, defined by industrial processing characteristics: 1 - in natura/minimally processed, 2 - processed, and 3 - ultra-processed. The percentage of calories from each group was estimated by categories of race/skin color - White, Black, Mixed-race, Indigenous, and Yellow- using crude and adjusted linear regression for gender, age, schooling, income, macro-region, and area.

RESULTS

In the crude analyses, the consumption of in natura/minimally processed foods was lower for Yellow [66.0% (95% Confidence Interval 62.4-69.6)] and White [66.6% (95%CI 66.1-67.1)] groups than for Blacks [69.8% (95%CI 68.9-70.8)] and Mixed-race people [70.2% (95%CI 69.7-70.7)]. Yellow individuals consumed fewer processed foods, with 9.2% of energy (95%CI 7.2-11.1) whereas the other groups consumed approximately 13%. Ultra-processed foods were less consumed by Blacks [16.6% (95%CI 15.6-17.6)] and Mixed-race [16.6% (95%CI 16.2-17.1)], with the highest consumption among White [20.1% (95%CI 19.6-20.6)] and Yellow [24.5% (95%CI 20.0-29.1)] groups. The adjustment of the models reduced the magnitude of the differences between the categories of race/skin color. The difference between Black and Mixed-race individuals from the White ones decreased from 3 percentage points (pp) to 1.2 pp in the consumption of in natura/minimally processed foods and the largest differences remained in the consumption of rice and beans, with a higher percentage in the diet of Black and Mixed-race people. The contribution of processed foods remained approximately 4 pp lower for Yellow individuals. The consumption of ultra-processed products decreased by approximately 2 pp for White and Yellow groups; on the other hand, it increased by 1 pp in the consumption of Black, Mixed-race, and Indigenous peoples.

CONCLUSION

Differences in food consumption according to race/skin color were found and are influenced by socioeconomic and demographic conditions.

Racial-Ethnic Disparities in Benzodiazepine Prescriptions for Anxiety in US Emergency Departments

BACKGROUND/OBJECTIVES

Benzodiazepines are commonly used to treat anxiety and panic disorders. White patients are more likely to receive a benzodiazepine prescription than non-White patients in different medical settings. Racial-ethnic disparities have also been found in prescription of opioids from the emergency room. It is not known whether racial disparities in benzodiazepine prescriptions exist at the emergency department level. This study aims to analyze the relationship between benzodiazepine prescriptions for anxiety in an emergency department setting.

DESIGN

Data for this cross-sectional study was obtained from the National Hospital Ambulatory Medical Care Survey (NHAMCS) Years 2009-2018. Patients ≥ 18 years of age presenting to the emergency department with anxiety were identified. Adjusted survey logistic regression was conducted to evaluate the patient characteristics and receipt of benzodiazepines.

RESULTS

This study analyzed 1,174,556,119 emergency department (ED) visits out of which 2.8% had a diagnosis of anxiety disorder. Prevalence of anxiety was higher in the following groups: females, younger age range (18-34 years old), and non-Hispanic (NH) White. Rates of benzodiazepine prescription for patients with anxiety were higher for NH-White and Hispanic patients at 29% and 28% respectively than for NH-Black and NH-Other (24% and 21% respectively). Compared to NH-White patients, NH-Black patients were 36% less likely to be prescribed a benzodiazepine (prevalence ratio (PR) = 0.64; 95% confidence interval (CI) = 0.54-0.76) and Hispanic patients were 19% less likely to be prescribed a benzodiazepine (PR = 0.81; 95% CI = 0.68-0.96). Age, sex, or type of insurance did not show a statistically significant influence in the prescription of benzodiazepines.

CONCLUSIONS

These findings reveal that NH-Black and Hispanic patients with anxiety are significantly less likely to be prescribed benzodiazepines than their NH-White counterparts in the ED. Further studies are needed to determine the root causes of these health disparities and strategies to combat them.

Characterising a syndemic among black women at risk for HIV: the role of sociostructural inequity and adverse childhood experiences

Objectives Black women disproportionately experience STIs (including HIV/AIDS), gender-based violence, substance misuse and mental health conditions. Addressing a gap in syndemic research, we characterised comorbidity overlap within the context of sociostructural inequities and adverse childhood experiences (ACEs) among black women in Baltimore, Maryland. Methods Between 2015 and 2018, black women (n=305) were recruited from STI clinics in Baltimore, Maryland. Among those with complete survey data (n=230), we conducted a latent class analysis to differentiate women based on their profile of the following syndemic comorbidities: STIs, adult sexual victimisation, substance misuse and mental health disorders. We then examined the association between ACEs and syndemic latent class membership. Results Thirty-three percent of women experienced three to nine ACEs before age 18 years, and 44% reported four to six comorbidities. The two-class latent class solution demonstrated the best fit model, and women were categorised in either class 1 (past-year STI; 59%) or class 2 (syndemic comorbidities; 41%). Women in class 2 were more likely to report unstable housing (10% vs 3%) and identify as bisexual/gay (22% vs 10%) than women in class 1. ACEs were significantly associated with an increased likelihood of class 2 membership. Conclusions This study reinforces the importance of screening for ACEs and offering trauma-informed, integrated care for black women with syndemic comorbidities. It also highlights the critical nature of tailoring interventions to improve sociostructural equity, preventing and reducing syndemic development.

Implications of missingness in self-reported data for estimating racial and ethnic disparities in Medicaid quality measures

OBJECTIVE

To assess the feasibility and implications of imputing race and ethnicity for quality and utilization measurement in Medicaid.

DATA SOURCES AND STUDY SETTING

2017 Oregon Medicaid claims from the Oregon Health Authority and electronic health records (EHR) from OCHIN, a clinical data research network, were used.

STUDY DESIGN

We cross-sectionally assessed Hispanic-White, Black-White, and Asian-White disparities in 22 quality and utilization measures, comparing self-reported race and ethnicity to imputed values from the Bayesian Improved Surname Geocoding (BISG) algorithm.

DATA COLLECTION

Race and ethnicity were obtained from self-reported data and imputed using BISG.

PRINCIPAL FINDINGS

42.5%/4.9% of claims/EHR were missing self-reported data; BISG estimates were available for >99% of each and had good concordance (0.87-0.95) with Asian, Black, Hispanic, and White self-report. All estimated racial and ethnic disparities were statistically similar in self-reported and imputed EHR-based measures. However, within claims, BISG estimates and incomplete self-reported data yielded substantially different disparities in almost half of the measures, with BISG-based Black-White disparities generally larger than self-reported race and ethnicity data.

CONCLUSIONS

BISG imputation methods are feasible for Medicaid claims data and reduced missingness to <1%. Disparities may be larger than what is estimated using self-reported data with high rates of missingness.

Results of genetic analysis of 11 341 participants enrolled in the My Life, Our Future hemophilia genotyping initiative in the United States

BACKGROUND

Hemophilia A (HA) and hemophilia B (HB) are rare inherited bleeding disorders. Although causative genetic variants are clinically relevant, in 2012 only 20% of US patients had been genotyped.

OBJECTIVES

My Life, Our Future (MLOF) was a multisector cross-sectional US initiative to improve our understanding of hemophilia through widespread genotyping.

METHODS

Subjects and potential genetic carriers were enrolled at US hemophilia treatment centers (HTCs). Bloodworks performed genotyping and returned results to providers. Clinical data were abstracted from the American Thrombosis and Hemostasis Network dataset. Community education was provided by the National Hemophilia Foundation.

RESULTS

From 2013 to 2017, 107 HTCs enrolled 11 341 subjects (68.8% male, 31.2% female) for testing for HA (n = 8976), HB (n = 2358), HA/HB (n = 3), and hemophilia not otherwise specified (n = 4). Variants were detected in most male patients (98.2%% HA, 98.1% HB). 1914 unique variants were found (1482 F8, 431 F9); 744 were novel (610 F8, 134 F9). Inhibitor data were available for 6986 subjects (5583 HA; 1403 HB). In severe HA, genotypes with the highest inhibitor rates were large deletions (77/80), complex intron 22 inversions (9/17), and no variant found (7/14). In severe HB, the highest rates were large deletions (24/42). Inhibitors were reported in 27.3% of Black versus 16.2% of White patients.

CONCLUSIONS

The findings of MLOF are reported, the largest hemophilia genotyping project performed to date. The results support the need for comprehensive genetic approaches in hemophilia. This effort has contributed significantly towards better understanding variation in the F8 and F9 genes in hemophilia and risks of inhibitor formation.

Associations of Clinical and Social Risk Factors With Racial Differences in Premature Cardiovascular Disease

BACKGROUND

Racial differences in cardiovascular disease (CVD) are likely related to differences in clinical and social factors. The relative contributions of these factors to Black-White differences in premature CVD have not been investigated.

METHODS

In Black and White adults aged 18 to 30 years at baseline in the CARDIA study (Coronary Artery Risk Development in Young Adults), the associations of clinical, lifestyle, depression, socioeconomic, and neighborhood factors across young adulthood with racial differences in incident premature CVD were evaluated in sex-stratified, multivariable-adjusted Cox proportional hazards models using multiply imputed data assuming missing at random. Percent reduction in the β estimate (log-hazard ratio [HR]) for race quantified the contribution of each factor group to racial differences in incident CVD.

RESULTS

Among 2785 Black and 2327 White participants followed for a median 33.9 years (25th-75th percentile, 33.7-34.0), Black (versus White) adults had a higher risk of incident premature CVD (Black women: HR, 2.44 [95% CI, 1.71-3.49], Black men: HR, 1.59 [1.20-2.10] adjusted for age and center). Racial differences were not statistically significant after full adjustment (Black women: HR, 0.91 [0.55-1.52], Black men: HR 1.02 [0.70-1.49]). In women, the largest magnitude percent reduction in the β estimate for race occurred with adjustment for clinical (87%), neighborhood (32%), and socioeconomic (23%) factors. In men, the largest magnitude percent reduction in the β estimate for race occurred with an adjustment for clinical (64%), socioeconomic (50%), and lifestyle (34%) factors.

CONCLUSIONS

In CARDIA, the significantly higher risk for premature CVD in Black versus White adults was statistically explained by adjustment for antecedent multilevel factors. The largest contributions to racial differences were from clinical and neighborhood factors in women, and clinical and socioeconomic factors in men.

New York State Paid Family Leave Law Associated with Increased Breastfeeding Among Black Women

Background: While breastfeeding has increased during the past 50 years, disparities continue, with Black women having the lowest rates. Use of paid leave has been associated with longer breastfeeding duration. Objective: Evaluate the impact of New York (NY)'s Paid Family Leave (PFL) law on breastfeeding, after it became effective on January 1, 2018. Materials and Methods: Women in NY (excluding NY City), who gave birth in 2016-2019 and completed the Pregnancy Risk Assessment and Monitoring System (PRAMS) survey, were included. Data from PRAMS and the NY State Expanded Birth Certificate were combined. Changes in breastfeeding initiation and duration and use of paid leave were compared, before and after NY's PFL law became effective, with separate analysis by sociodemographic factors. Results: Before NYPFL, Black women were least likely to initiate breastfeeding and breastfed for the shortest duration. After NYPFL went into effect, breastfeeding initiation and duration to 8 weeks increased for Black women, but not for other racial/ethnic groups; these findings persisted after adjustment for sociodemographic factors. Use of paid leave after childbirth increased 15% overall, with greater increases among Black women and Hispanic women. Conclusions: Implementation of the NYPFL law was associated with increased breastfeeding among Black women and increased use of paid leave by all. Greater increases in breastfeeding among Black women significantly reduced breastfeeding disparities by race/ethnicity. More widespread implementation of PFL programs in the United States would promote equity in the use of paid leave, which could reduce disparities in breastfeeding initiation and duration and possibly improve infant and maternal health outcomes.

COVID-19 and Mental Health Disparities in the Black American Population

Description The current COVID-19 pandemic has amplified health disparities that have long existed for minoritized groups in the United States. There have been disproportionate effects on the mental and physical health of the Black American population, specifically because of longstanding racial, social, and economic injustices. To fully understand the current state of Black mental health and the extent to which COVID-19 has impacted it, we examine historical examples of unjust mental health practices throughout generations. We then explore why depression, suicidality, and other mental illnesses may have a profound effect on a community that has been made vulnerable to socioeconomic shifts. The complex interplay of individual stress, generational trauma, targeted violence, and mass catastrophe undermines the mental well-being of many Black Americans. This issue requires a multi-systems approach to improve trust in medicine and increase access to quality mental healthcare.

Impact of Racial Categorization on Effect Estimates: An HIV Stigma Analysis

Suboptimal racial categorization potentially introduces bias in epidemiologic analysis and interpretation, making it difficult to appropriately measure factors leading to racial health disparities. As part of an analysis focused on predictors of experiencing human immunodeficiency status (HIV)-related stigma among men who have sex with men living with HIV in San Francisco, we struggled with the most appropriate ways to categorize people who reported more than 1 racial identity, and we aimed to explore the implications of different methodological choices in this analysis. We fitted 3 different multivariable linear regression models, each utilizing a different approach to racial categorization: the "multiracial," "othering," and "hypodescent" models. We estimated an adjusted risk difference in mean score for reported frequency of experiencing HIV-related stigma on a 4-point scale, adjusting for age, race, gender identity, injection history, housing, mental health concerns, and viral load. Use of a hypodescent model for racial categorization led to a shift in the point estimate through the null for Blacks/African Americans, and it improved precision for that group. However, it obscured the association of increased stigma and race for multiracial people, compared with monoracial counterparts. We conclude that methodological decisions related to racial categorization of participants can dramatically affect race-related study findings in predictor regression models.

Association of Race and Neighborhood Disadvantage with Patient Engagement in a Home-Based COVID-19 Remote Monitoring Program

BACKGROUND

COVID-positive outpatients may benefit from remote monitoring, but such a program often relies on smartphone apps. This may introduce racial and socio-economic barriers to participation. Offering multiple methods for participation may address these barriers.

OBJECTIVES

(1) To examine associations of race and neighborhood disadvantage with patient retention in a monitoring program offering two participation methods. (2) To measure the association of the program with emergency department visits and hospital admissions.

DESIGN

Retrospective propensity-matched cohort study.

PARTICIPANTS

COVID-positive outpatients at a single university-affiliated healthcare system and propensity-matched controls.

INTERVENTIONS

A home monitoring program providing daily symptom tracking via patient portal app or telephone calls.

MAIN MEASURES

Among program enrollees, retention (until 14 days, symptom resolution, or hospital admission) by race and neighborhood disadvantage, with stratification by program arm. In enrollees versus matched controls, emergency department utilization and hospital admission within 30 days.

KEY RESULTS

There were 7592 enrolled patients and 9710 matched controls. Black enrollees chose the telephone arm more frequently than White enrollees (68% versus 44%, p = 0.009), as did those from more versus less disadvantaged neighborhoods (59% versus 43%, p = 0.02). Retention was similar in Black enrollees and White enrollees (63% versus 62%, p = 0.76) and in more versus less disadvantaged neighborhoods (63% versus 62%, p = 0.44). When stratified by program arm, Black enrollees had lower retention than White enrollees in the app arm (49% versus 55%, p = 0.01), but not in the telephone arm (69% versus 71%, p = 0.12). Compared to controls, enrollees more frequently visited the emergency department (HR 1.71 [95% CI 1.56-1.87]) and were admitted to the hospital (HR 1.16 [95% CI 1.02-1.31]).

CONCLUSIONS

In a COVID-19 remote patient monitoring program, Black enrollees preferentially selected, and had higher retention in, telephone- over app-based monitoring. As a result, overall retention was similar between races. Remote monitoring programs with multiple modes may reduce barriers to participation.

Using a Patient Portal to Increase Enrollment in a Newborn Screening Research Study: Observational Study

BACKGROUND

Many research studies fail to enroll enough research participants. Patient-facing electronic health record applications, known as patient portals, may be used to send research invitations to eligible patients.

OBJECTIVE

The first aim was to determine if receipt of a patient portal research recruitment invitation was associated with enrollment in a large ongoing study of newborns (Early Check). The second aim was to determine if there were differences in opening the patient portal research recruitment invitation and study enrollment by race and ethnicity, age, or rural/urban home address.

METHODS

We used a computable phenotype and queried the health care system's clinical data warehouse to identify women whose newborns would likely be eligible. Research recruitment invitations were sent through the women's patient portals. We conducted logistic regressions to test whether women enrolled their newborns after receipt of a patient portal invitation and whether there were differences by race and ethnicity, age, and rural/urban home address.

RESULTS

Research recruitment invitations were sent to 4510 women not yet enrolled through their patient portals between November 22, 2019, through March 5, 2020. Among women who received a patient portal invitation, 3.6% (161/4510) enrolled their newborns within 27 days. The odds of enrolling among women who opened the invitation was nearly 9 times the odds of enrolling among women who did not open their invitation (SE 3.24, OR 8.86, 95% CI 4.33-18.13; P<.001). On average, it took 3.92 days for women to enroll their newborn in the study, with 64% (97/161) enrolling their newborn within 1 day of opening the invitation. There were disparities by race and urbanicity in enrollment in the study after receipt of a patient portal research invitation but not by age. Black women were less likely to enroll their newborns than White women (SE 0.09, OR 0.29, 95% CI 0.16-0.55; P<.001), and women in urban zip codes were more likely to enroll their newborns than women in rural zip codes (SE 0.97, OR 3.03, 95% CI 1.62-5.67; P=.001). Black women (SE 0.05, OR 0.67, 95% CI 0.57-0.78; P<.001) and Hispanic women (SE 0.07, OR 0.73, 95% CI 0.60-0.89; P=.002) were less likely to open the research invitation compared to White women.

CONCLUSIONS

Patient portals are an effective way to recruit participants for research studies, but there are substantial racial and ethnic disparities and disparities by urban/rural status in the use of patient portals, the opening of a patient portal invitation, and enrollment in the study.

Diagnosing Mild Cognitive Impairment Among Racially Diverse Older Adults: Comparison of Consensus, Actuarial, and Statistical Methods

BACKGROUND

Actuarial and statistical methods have been proposed as alternatives to conventional methods of diagnosing mild cognitive impairment (MCI), with the aim of enhancing diagnostic and prognostic validity, but have not been compared in racially diverse samples.

OBJECTIVE

We compared the agreement of consensus, actuarial, and statistical MCI diagnostic methods, and their relationship to race and prognostic indicators among diverse older adults.

METHODS

Participants (N = 354; M age = 71; 68% White, 29% Black) were diagnosed with MCI or normal cognition (NC) according to clinical consensus, actuarial neuropsychological criteria (Jak/Bondi), and latent class analysis (LCA). We examined associations with race/ethnicity, longitudinal cognitive and functional change, and incident dementia.

RESULTS

MCI rates by consensus, actuarial criteria, and LCA were 44%, 53%, and 41%, respectively. LCA identified three MCI subtypes (memory; memory/language; memory/executive) and two NC classes (low normal; high normal). Diagnostic agreement was substantial, but agreement of the actuarial method with consensus and LCA was weaker than the agreement between consensus and LCA. Among cases classified as MCI by actuarial criteria only, Black participants were over-represented, and outcomes were generally similar to those of NC participants. Consensus diagnoses best predicted longitudinal outcomes overall, whereas actuarial diagnoses best predicted longitudinal functional change among Black participants.

CONCLUSION

Consensus diagnoses optimize specificity in predicting dementia, but among Black older adults, actuarial diagnoses may be more sensitive to early signs of decline. Results highlight the need for cross-cultural validity in MCI diagnosis and should be explored in community- and population-based samples.

Lofty goals and strategic plans are not enough to achieve and maintain a diverse workforce: an American Association for the Surgery of Trauma Diversity, Equity, and Inclusion Committee conversation

The American Association for the Surgery of Trauma Diversity, Equity, and Inclusion (DEI) Ad Hoc Committee organized a luncheon symposium with a distinguished panel of experts to discuss how to ensure a diverse surgical workforce. The panelists discussed the current state of DEI efforts within surgical departments and societal demographic changes that inform and necessitate surgical workforce adaptations. Concrete recommendations included the following: obtain internal data, establish DEI committee, include bias training, review hiring and compensation practices, support the department members doing the DEI work, commit adequate funding, be intentional with DEI efforts, and develop and support alternate pathways for promotion and tenure.

Distinct Microbial Signatures between Periodontal Profile Classes

Precise classification of periodontal disease has been the objective of concerted efforts and has led to the introduction of new consensus-based and data-driven classifications. The purpose of this study was to characterize the microbiological signatures of a latent class analysis (LCA)-derived periodontal stratification system, the Periodontal Profile Class (PPC) taxonomy. We used demographic, microbial (subgingival biofilm composition), and immunological data (serum IgG antibody levels, obtained with checkerboard immunoblotting technique) for 1,450 adult participants of the Dental Atherosclerosis Risk in Communities (ARIC) study, with already generated PPC classifications. Analyses relied on t tests and generalized linear models with Bonferroni correction. Men and African Americans had higher systemic antibody levels against most microorganisms compared to women and Caucasians (P < 0.05). Healthy individuals (PPC-I) had low levels of biofilm bacteria and serum IgG levels against most periodontal pathogens (P < 0.05). Subjects with mild to moderate disease (PPC-II to PPC-III) showed mild/moderate colonization of multiple biofilm pathogens. Individuals with severe disease (PPC-IV) had moderate/high levels of biofilm pathogens and antibody levels for orange/red complexes. High gingival index individuals (PPC-V) showed moderate/high levels of biofilm Campylobacter rectus and Aggregatibacter actinomycetemcomitans. Biofilm composition in individuals with reduced periodontium (PPC-VI) was similar to health but showed moderate to high antibody responses. Those with severe tooth loss (PPC-VII) had significantly high levels of multiple biofilm pathogens, while the systemic antibody response to these microorganisms was comparable to health. The results support a biologic basis for elevated risk for periodontal disease in men and African Americans. Periodontally healthy individuals showed a low biofilm pathogen and low systemic antibody burden. In the presence of PPC disease, a microbial-host imbalance characterized by higher microbial biofilm colonization and/or systemic IgG responses was identified. These results support the notion that subgroups identified by the PPC system present distinct microbial profiles and may be useful in designing future precise biological treatment interventions.

Factors Associated with Time to Conversion from Active Surveillance to Treatment for Prostate Cancer in a Multi-Institutional Cohort

PURPOSE

We examined the demographic and clinicopathological parameters associated with the time to convert from active surveillance to treatment among men with prostate cancer.

MATERIALS AND METHODS

A multi-institutional cohort of 7,279 patients managed with active surveillance had data and biospecimens collected for germline genetic analyses.

RESULTS

Of 6,775 men included in the analysis, 2,260 (33.4%) converted to treatment at a median followup of 6.7 years. Earlier conversion was associated with higher Gleason grade groups (GG2 vs GG1 adjusted hazard ratio [aHR] 1.57, 95% CI 1.36-1.82; ≥GG3 vs GG1 aHR 1.77, 95% CI 1.29-2.43), serum prostate specific antigen concentrations (aHR per 5 ng/ml increment 1.18, 95% CI 1.11-1.25), tumor stages (cT2 vs cT1 aHR 1.58, 95% CI 1.41-1.77; ≥cT3 vs cT1 aHR 4.36, 95% CI 3.19-5.96) and number of cancerous biopsy cores (3 vs 1-2 cores aHR 1.59, 95% CI 1.37-1.84; ≥4 vs 1-2 cores aHR 3.29, 95% CI 2.94-3.69), and younger age (age continuous per 5-year increase aHR 0.96, 95% CI 0.93-0.99). Patients with high-volume GG1 tumors had a shorter interval to conversion than those with low-volume GG1 tumors and behaved like the higher-risk patients. We found no significant association between the time to conversion and self-reported race or genetic ancestry.

CONCLUSIONS

A shorter time to conversion from active surveillance to treatment was associated with higher-risk clinicopathological tumor features. Furthermore, patients with high-volume GG1 tumors behaved similarly to those with intermediate and high-risk tumors. An exploratory analysis of self-reported race and genetic ancestry revealed no association with the time to conversion.

A prospective study of multiple sleep dimensions and hypertension risk among white, black and Hispanic/Latina women: findings from the Sister Study

BACKGROUND

Poor sleep is associated with increased hypertension risk, but few studies have evaluated multiple sleep dimensions or investigated racial/ethnic disparities in this association among women.

METHOD

We investigated multiple sleep dimensions (sleep duration, inconsistent weekly sleep patterns, sleep debt, frequent napping and difficulty falling or staying asleep) and hypertension risk among women, and determined modification by age, race/ethnicity and menopausal status. We used data from the Sister Study, a national cohort of 50 884 women who had sisters diagnosed with breast cancer in the United States enrolled in 2003-2009 and followed through September 2018.

RESULTS

Of 33 497 women without diagnosed hypertension at baseline (mean age ± standard deviation: 53.9 ± 8.8 years; 88.7% White, 6.4% Black and 4.9% Hispanic/Latina), 23% (n = 7686) developed hypertension over a median follow-up of 10.1 years [interquartile range: 8.2-11.9 years]. Very short, short or long sleep duration, inconsistent weekly sleep patterns, sleep debt, frequent napping, insomnia, insomnia symptoms as well as short sleep and exploratory cumulative poor sleep score were associated with incident hypertension after adjustment for demographics factors. After additional adjustment for lifestyle and clinical factors, insomnia [hazard ratio = 1.09, 95% confidence interval (95% CI): 1.03-1.15] and insomnia symptoms plus short sleep (hazard ratio = 1.13, 95% CI: 1.05-1.21) remained associated with incident hypertension. These associations were stronger in younger (age<54 vs. ≥54 years) and premenopausal vs. postmenopausal women (all P-interaction < 0.05). Associations did not differ by race/ethnicity (all P-interaction > 0.05).

CONCLUSION

Thus, screening for multiple sleep dimensions and prioritizing younger and premenopausal women may help identify individuals at high risk for hypertension.

AHORA: a Spanish language tool to identify acute stroke symptoms

OBJECTIVE

To develop a Spanish language tool for acute stroke identification.

METHODS

A Spanish language translation of the Balance-Eyes-Face-Arm-Speech-Time tool was developed within our emergency medical services agency.

RESULTS

The authors present a new prehospital stroke tool, Andar, Hablar, Ojos, Rostro and Ambos Brazos o Piernas (AHORA) (which means now in Spanish) to help combat the language barrier and reinforce the necessity to call 9-1-1 as soon as any stroke symptoms are noted.

CONCLUSION

AHORA is a Spanish language tool that aims to help Spanish-speaking individuals to identify an acute stroke and obtain prompt help.

Impact of Race on Clinical Outcomes After Implantation With a Fully Magnetically Levitated Left Ventricular Assist Device: An Analysis From the MOMENTUM 3 Trial

BACKGROUND

Heart failure disproportionately affects Black patients. Whether differences among race influence outcomes in advanced heart failure with use of a fully magnetically levitated continuous-flow left ventricular assist device remains uncertain.

METHODS

We included 515 IDE (Investigational Device Exemption) clinical trial patients and 500 Continued Access Protocol patients implanted with the HeartMate 3 left ventricular assist device in the MOMENTUM 3 study (Multicenter Study of MagLev Technology in Patients Undergoing Mechanical Circulatory Support Therapy With HeartMate 3). Outcomes were compared between Black and White left ventricular assist device recipients for the primary end point of survival free of disabling stroke or reoperation to replace or remove a malfunctioning device at 2 years, overall survival, adverse events, 6-minute walk distance, and quality of life scores.

RESULTS

Of 1015 HeartMate 3 patients, 675 were self-identified as White and 285 as Black individuals. The Black patient cohort was younger, more obese and with a history of hypertension, and more nonischemic cause of heart failure, relative to the White patient group. Black and White patients did not experience a difference in the primary end point (81.1% versus 77.9%; hazard ratio, 1.08 [95% CI, 0.76-1.54], P=0.6568). Black patients were at higher risk of adverse events (calculated as events per 100 patient-years), including bleeding (75.4 versus 63.5; P<0.0001), stroke (9.5 versus 7.2; P=0.0183), and hypertension (10.1 versus 3.2; P<0.0001). The 6-minute walk distance was not different at baseline and 6 months between the groups, however, the absolute change from baseline was greater for White patients (median: +183.0 [interquartile range, 42.0-335.3] versus +163.8 [interquartile range, 42.3-315.0] meters, P=0.01). The absolute quality of life measurement (EuroQoL group, 5-dimension, 5-level instrument visual analog scale) at baseline and 6 months was better in the Black patient group, but relative improvement from baseline to 6 months was greater in White patients (median: +20.0 [interquartile range, 5.0-40.0] versus +25.0 [interquartile range, 10.0-45.0]; P=0.0298).

CONCLUSIONS

Although the survival free of disabling stroke or reoperation to replace/remove a malfunctioning device at 2 years with the HM 3 left ventricular assist device did not differ by race, Black HeartMate 3 patients experienced a higher morbidity burden and smaller gains in functional capacity and quality of life when compared with White patients. These findings require efforts designed to better understand and overcome these gaps through systematic identification and tackling of putative factors.

Relationships Between Chronic Pain Stage, Cognition, Temporal Lobe Cortex, and Sociodemographic Variables

BACKGROUND

Non-Hispanic black (NHB) individuals have increased risk of Alzheimer's disease (AD) relative to non-Hispanic whites (NHW). Ethnicity/race can serve as a proxy sociodemographic variable for a complex representation of sociocultural and environmental factors. Chronic pain is a form of stress with high prevalence and sociodemographic disparities. Chronic pain is linked to lower cognition and accelerated biological aging.

OBJECTIVE

The purpose of this study is to seek understanding of potential cognitive and temporal lobe structural brain AD vulnerabilities based on chronic pain stage and ethnicity/race.

METHODS

Participants included 147 community dwelling NHB and NHW adults without dementia between 45-85 years old who had or were at risk of knee osteoarthritis. All participants received an MRI (3T Philips), the Montreal Cognitive Assessment (MoCA), and assessment of clinical knee pain stage.

RESULTS

There were ethnic/race group differences in MoCA scores but no relationships with chronic knee pain stage. Ethnicity/race moderated the relationship between AD-related temporal lobe thickness and chronic pain stage with quadratic patterns suggesting thinner cortex in high chronic pain stage NHB adults.

CONCLUSION

There appear to be complex relationships between chronic knee pain stage, temporal lobe cortex, and sociodemographic variables. Specifically, NHB participants without dementia but with high chronic knee pain stage appeared to have thinner temporal cortex in areas associated with AD. Understanding the effects of sociocultural and socioeconomic factors on health outcomes is the first step to challenging the disparities in healthcare that now appear to link disease conditions to neurodegenerative processes.

Obesity, Race, and COVID-19 Mortality: Results from a Large Cohort Early in the Pandemic

Background

Obesity has increased progressively in the United States and is a known risk factor for several diseases such as type 2 diabetes, coronary artery disease, stroke and hypertension. Amid the current pandemic, concerns have been raised about obesity as a risk factor for COVID-19 positive patients. The primary goal of this study was to explore the association between obesity and hospital mortality in COVID-19 patients. Our secondary objective was to explore the relationship between obesity and race on hospital mortality in COVID-19 patients.

Methods

This was a cross-sectional, retrospective analysis using data from 186 hospitals from across the United States and the United Kingdom during the first quarter of 2020. Extraction provided data from 25,894 patients who were tested for COVID-19, of whom 2,977 were positive. Patients were stratified into standard WHO categories for BMI and by race.

Results

Bivariate analysis revealed significant relationships between mortality and sex (p<0.001) When BMI was analyzed as a continuous variable, multivariate analysis revealed a significant influence of BMI on mortality (odds ratio=1.291, p<0.05).

Conclusion

COVID-19 mortality was significantly related to BMI, age and select co-morbidities, but race/ethnicity was not a predictor of mortality when controlling for other variables.

Association of Race and Ethnicity with COVID-19 Test Positivity and Hospitalization Is Mediated by Socioeconomic Factors

Rationale: Black race and Hispanic ethnicity are associated with increased risks for coronavirus disease (COVID-19) infection and severity. It is purported that socioeconomic factors may drive this association, but data supporting this assertion are sparse. Objectives: To evaluate whether socioeconomic factors mediate the association of race/ethnicity with COVID-19 incidence and outcomes. Methods: We conducted a retrospective cohort study of adults tested for (cohort 1) or hospitalized with (cohort 2) COVID-19 between March 1, 2020, and July 23, 2020, at the University of Miami Hospital and Clinics. Our primary exposure was race/ethnicity. We considered socioeconomic factors as potential mediators of our exposure's association with outcomes. We used standard statistics to describe our cohorts and multivariable regression modeling to identify associations of race/ethnicity with our primary outcomes, one for each cohort, of test positivity (cohort 1) and hospital mortality (cohort 2). We performed a mediation analysis to see whether household income, population density, and household size mediated the association of race/ethnicity with outcomes. Results: Our cohorts included 15,473 patients tested (29.0% non-Hispanic White, 48.1% Hispanic White, 15.0% non-Hispanic Black, 1.7% Hispanic Black, and 1.6% other) and 295 patients hospitalized (9.2% non-Hispanic White, 56.9% Hispanic White, 21.4% non-Hispanic Black, 2.4% Hispanic Black, and 10.2% other). Among those tested, 1,256 patients (8.1%) tested positive, and, of the hospitalized patients, 47 (15.9%) died. After adjustment for demographics, race/ethnicity was associated with test positivity-odds-ratio (95% confidence interval [CI]) versus non-Hispanic White for Non-Hispanic Black: 3.21 (2.60-3.96), Hispanic White: 2.72 (2.28-3.26), and Hispanic Black: 3.55 (2.33-5.28). Population density mediated this association (percentage mediated, 17%; 95% CI, 11-31%), as did median income (27%; 95% CI, 18-52%) and household size (20%; 95% CI, 12-45%). There was no association between race/ethnicity and mortality, although this analysis was underpowered. Conclusions: Black race and Hispanic ethnicity are associated with an increased odds of COVID-19 positivity. This association is substantially mediated by socioeconomic factors.

Trends, mechanisms, and racial/ethnic differences of tuberculosis incidence in the US-born population aged 50 years or older in the United States

Background

Older age is a risk factor for tuberculosis (TB) in low incidence settings. Using data from the US National TB Surveillance System and American Community Survey, we estimated trends and racial/ethnic differences in TB incidence among US-born cohorts aged ≥50 years.

Methods

In total, 42 000 TB cases among US-born persons ≥50 years were reported during 2001–2019. We used generalized additive regression models to decompose the effects of birth cohort and age on TB incidence rates, stratified by sex and race/ethnicity. Using genotype-based estimates of recent transmission (available 2011–2019), we implemented additional models to decompose incidence trends by estimated recent versus remote infection.

Results

Estimated incidence rates declined with age, for the overall cohort and most sex and race/ethnicity strata. Average annual percentage declines flattened for older individuals, from 8.80% (95% confidence interval [CI] 8.34–9.23) in 51-year-olds to 4.51% (95% CI 3.87–5.14) in 90-year-olds. Controlling for age, incidence rates were lower for more recent birth cohorts, dropping 8.79% (95% CI 6.13–11.26) on average between successive cohort years. Incidence rates were substantially higher for racial/ethnic minorities, and these inequalities persisted across all birth cohorts. Rates from recent infection declined at approximately 10% per year as individuals aged. Rates from remote infection declined more slowly with age, and this annual percentage decline approached zero for the oldest individuals.

Conclusions

TB rates were highest for racial/ethnic minorities and for the earliest birth cohorts and declined with age. For the oldest individuals, annual percentage declines were low, and most cases were attributed to remote infection.

Dental Visits during Pregnancy: Pregnancy Risk Assessment Monitoring System Analysis 2012-2015

OBJECTIVES

This study aimed to update dental service utilization during pregnancy and to evaluate whether there are persistent disparities in dental care during pregnancy by race/ethnicity and Medicaid status.

METHODS

This retrospective secondary data analysis examined dental service utilization during and prior to pregnancy and met dental or oral health needs using the Pregnancy Risk Assessment Monitoring System (PRAMS) data sets on 75,876 women between 2012 and 2015.

RESULTS

Only about half of the women (51.7%) reported that they had at least 1 dental visit for cleaning during their most recent pregnancy. One of 5 women (19.7%) experienced dental problems during pregnancy, and 34.4% of these women did not visit dentists to address the problems. Non-Hispanic Black women had 14% lower odds of visiting dentists for cleaning during pregnancy compared to non-Hispanic White women (odds ratio [OR], 0.86; 95% CI confidence interval [CI], 0.80-0.92). There was no difference in dental visits prior to pregnancy between non-Hispanic Black and White women. Women enrolled in Medicaid showed significantly lower odds of visiting dentists for cleaning during pregnancy compared to women covered by private health insurance (OR, 0.55; 95% CI, 0.52-0.58).

CONCLUSION FOR PRACTICE

Oral health, as an integral part of primary care, needs to be included in the standard prenatal care through oral health education and timely dental care during pregnancy. With mounting evidence of persisting disparities in dental service utilization during pregnancy, both public and private prenatal programs and policies should address specific barriers in accessing and using dental care during pregnancy, especially for women from socially disadvantaged backgrounds.

KNOWLEDGE TRANSFER STATEMENT

The current study updated the previous findings with more recent multiyear PRAMS data (2012-2015) and found the Black-White disparity and disparity among Medicaid-enrolled women in visiting dentists during pregnancy persist. The results of this study can be used by policymakers and practitioners to integrate oral health into prenatal care for pregnant women from marginalized backgrounds to achieve oral health parity.

Social inequalities and COVID-19 mortality in the city of São Paulo, Brazil

BACKGROUND

Heterogeneity in COVID-19 morbidity and mortality is often associated with a country's health-services structure and social inequality. This study aimed to characterize social inequalities in COVID-19 mortality in São Paulo, the most populous city in Brazil and Latin America.

METHODS

We conducted a population-based study, including COVID-19 deaths among São Paulo residents from March to September 2020. Age-standardized mortality rates and unadjusted rate ratios (RRs) [with corresponding 95% confidence intervals (CIs)] were estimated by race, sex, age group, district of residence, household crowding, educational attainment, income level and percentage of households in subnormal areas in each district. Time trends in mortality were assessed using the Joinpoint model.

RESULTS

Males presented an 84% increase in COVID-19 mortality compared with females (RR = 1.84, 95% CI 1.79-1.90). Higher mortality rates were observed for Blacks (RR = 1.77, 95% CI 1.67-1.88) and mixed (RR = 1.42, 95% CI 1.37-1.47) compared with Whites, whereas lower mortality was noted for Asians (RR = 0.63, 95% CI 0.58-0.68). A positive gradient was found for all socio-economic indicators, i.e. increases in disparities denoted by less education, more household crowding, lower income and a higher concentration of subnormal areas were associated with higher mortality rates. A decrease in mortality over time was observed in all racial groups, but it started earlier among Whites and Asians.

CONCLUSION

Our results reveal striking social inequalities in COVID-19 mortality in São Paulo, exposing structural inequities in Brazilian society that were not addressed by the governmental response to COVID-19. Without an equitable response, COVID-19 will further exacerbate current social inequalities in São Paulo.

Racial, ethnic, and gender disparities in hospitalizations among persons with HIV in the United States and Canada, 2005-2015

OBJECTIVE

To examine recent trends and differences in all-cause and cause-specific hospitalization rates by race, ethnicity, and gender among persons with HIV (PWH) in the United States and Canada.

DESIGN

HIV clinical cohort consortium.

METHODS

We followed PWH at least 18 years old in care 2005-2015 in six clinical cohorts. We used modified Clinical Classifications Software to categorize hospital discharge diagnoses. Incidence rate ratios (IRR) were estimated using Poisson regression with robust variances to compare racial and ethnic groups, stratified by gender, adjusted for cohort, calendar year, injection drug use history, and annually updated age, CD4+, and HIV viral load.

RESULTS

Among 27 085 patients (122 566 person-years), 80% were cisgender men, 1% transgender, 43% White, 33% Black, 17% Hispanic of any race, and 1% Indigenous. Unadjusted all-cause hospitalization rates were higher for Black [IRR 1.46, 95% confidence interval (CI) 1.32-1.61] and Indigenous (1.99, 1.44-2.74) versus White cisgender men, and for Indigenous versus White cisgender women (2.55, 1.68-3.89). Unadjusted AIDS-related hospitalization rates were also higher for Black, Hispanic, and Indigenous versus White cisgender men (all P < 0.05). Transgender patients had 1.50 times (1.05-2.14) and cisgender women 1.37 times (1.26-1.48) the unadjusted hospitalization rate of cisgender men. In adjusted analyses, among both cisgender men and women, Black patients had higher rates of cardiovascular and renal/genitourinary hospitalizations compared to Whites (all P < 0.05).

CONCLUSION

Black, Hispanic, Indigenous, women, and transgender PWH in the United States and Canada experienced substantially higher hospitalization rates than White patients and cisgender men, respectively. Disparities likely have several causes, including differences in virologic suppression and chronic conditions such as diabetes and renal disease.

Rural and racial disparities in colorectal cancer incidence and mortality in South Carolina, 1996 - 2016

PURPOSE

Colorectal cancer (CRC) is the third leading cause of cancer mortality among men and women in the United States and South Carolina (SC). Since SC has one of the highest proportions of Black (27.9%) and rural residents (33.7%), the purpose of this investigation was to describe the burden of CRC on racial disparities in rural populations.

METHODS

Count data from 2012 to 2016 were obtained from the state central cancer registry using an online data retrieval system. Rural-urban status was determined using Urban Influence Codes (1-2 = urban; 3-12 = rural). Chi-square tests were calculated to examine differences in CRC stage by rurality and race. Annual percent change and annual average percent change (AAPC) were calculated to examine trends in incidence and mortality rates across rural-urban and racial groups between 1996 and 2016.

RESULTS

Areas with high mortality-to-incidence ratios tended to be in rural counties. Furthermore, rural residents had higher proportions of distant stage CRC compared to urban residents, and Black populations had higher proportions of distant stage CRC compared to White populations (22.7% vs. 26.3% and 29.3% vs. 23.7%, respectively; P value < 0.05). From 1996 to 2016, Black and White urban-dwelling residents experienced a significant decline in incidence. Urban White, urban Black, and rural White populations experienced significant declines in mortality (AAPC = -2.6% vs -2.4% vs -1.6% vs -0.9%, respectively).

CONCLUSIONS

Despite improvements in CRC screening in recent decades, focused evidenced-based interventions for lowering incidence and mortality among rural and Black populations in South Carolina are necessary.

Ethnic inequalities in mental health and socioeconomic status among older women living with HIV: results from the PRIME Study

Objectives

Women living with HIV in the UK are an ethnically diverse group with significant psychosocial challenges. Increasing numbers are reaching older age. We describe psychological and socioeconomic factors among women with HIV in England aged 45–60 and explore associations with ethnicity.

Methods

Analysis of cross-sectional data on 724 women recruited to the PRIME Study. Psychological symptoms were measured using the Patient Health Questionnaire 4 and social isolation with a modified Duke-UNC Functional Social Support Scale.

Results

Black African (BA) women were more likely than Black Caribbean or White British (WB) women to have a university education (48.3%, 27.0%, 25.7%, respectively, p<0.001), but were not more likely to be employed (68.4%, 61.4%, 65.2%, p=0.56) and were less likely to have enough money to meet their basic needs (56.4%, 63.0%, 82.9%, p<0.001). BA women were less likely to report being diagnosed with depression than WB women (adjusted odds ratio (aOR) 0.40, p<0.001) but more likely to report current psychological distress (aOR 3.34, p<0.05).

Conclusions

We report high levels of poverty, psychological distress and social isolation in this ethnically diverse group of midlife women with HIV, especially among those who were BA. Despite being more likely to experience psychological distress, BA women were less likely to have been diagnosed with depression suggesting a possible inequity in access to mental health services. Holistic HIV care requires awareness of the psychosocial needs of older women living with HIV, which may be more pronounced in racially minoritised communities, and prompt referral for support including psychology, peer support and advice about benefits.

Shifting patterns of disparities in unintentional injury mortality rates in the United States, 1999-2016

OBJECTIVES

To analyze changes in racial/ethnic disparities for unintentional injury mortality from 1999-2016.

METHODS

Mortality data are from the National Center for Health Statistics (NCHS) for all unintentional injuries, analyzed separately by injury cause (motor vehicle accidents [MVA], poisonings, other unintentional) for white,black, and Hispanic populations within four age groups: 15-19, 20-34, 35-54, 55-74 for males and for females.

RESULTS

Rates across race/ethnic groups varied by gender, age and cause of injury. Unintentional injury mortality showed a recent increase for both males and females, which was more marked among males and for poisoning in all race/ethnic groups of both genders. Whites showed highest rates of poisoning mortality and the steepest increase for both genders, except for black males aged 55-74. MVA mortality also showed an increase for all race/ethnic groups, with a sharper rise among blacks, while Hispanics had lower rates than either whites or blacks. Rates for other unintentional injury mortality were similar across groups except for white women over 55, for whom rates were elevated.

CONCLUSIONS

Data suggest while mortality from unintentional injury related to MVA and poisoning is on the rise for both genders and in most age groups, blacks compared to whites and Hispanics may be suffering a disproportionate burden of mortality related to MVAs and to poisonings among those over 55, which may be related to substance use.

Racial/Ethnic Disparities in Tumor Characteristics and Treatments in Favorable and Unfavorable Intermediate Risk Prostate Cancer

PURPOSE

We hypothesized that differences in active treatment rates may exist according to race/ethnicity in favorable as well as unfavorable intermediate risk prostate cancer.

MATERIALS AND METHODS

We relied on the Surveillance, Epidemiology, and End Results 18 database 2010-2015. We stratified according to 3 racial/ethnic groups (White vs Black vs Hispanic) and prostate cancer baseline characteristics (prostate specific antigen, clinical T stage, Gleason group grading, percentage of biopsy cores). We tabulated active treatment rates (radical prostatectomy, external beam radiotherapy) without and with adjustment for baseline age and prostate cancer characteristics.

RESULTS

Baseline prostate specific antigen, clinical T stage, Gleason grade and percentage of positive biopsy cores differed according to racial/ethnic groups in both favorable and unfavorable intermediate risk prostate cancer patients (all p <0.05). Similarly, radical prostatectomy and external beam radiotherapy rates differed according to race/ethnicity in both favorable and unfavorable intermediate risk prostate cancer patients. Radical prostatectomy and external beam radiotherapy rates respectively ranged from 31.7%-41.8% and 26.3%-31.0% in favorable intermediate risk cases and from 33.4%-43.9% and 30.9%-35.5% in unfavorable intermediate risk prostate cancer, across the 3 race/ethnicity groups (both p <0.05). The above heterogeneity in active treatment rates disappeared and marginal differences remained after adjustment for baseline age and prostate cancer characteristics.

CONCLUSIONS

Interpretation of active treatment rates in favorable and unfavorable intermediate risk prostate cancer may be severely biased, unless detailed and systematic consideration or adjustment for baseline age and prostate cancer characteristic is enforced.

Age-adjusted reference values for prostate-specific antigen in a multi-ethnic population

OBJECTIVE

To establish age-adjusted reference values for prostate-specific antigen in an ethnically diverse population.

METHODS

Between 2009 and 2017, data were collected from all men aged 40-79 years, who had a prostate-specific antigen test in the northern region of New Zealand, where the prostate-specific antigen testing service is provided by a single community laboratory and using the same assay analyzer. Men known to have prostate cancer, who developed prostate cancer during the study period, who were treated with finasteride, or who had prostate-specific antigen levels above 20 ng/mL were excluded. Age-adjusted prostate-specific antigen reference values were calculated for each of the main ethnic groups in the country including: Māori (indigenous), Pacific, Asian and European. For every 5-year age interval, the 95th percentile of the log prostate-specific antigen distribution was used to define the upper limit of normal.

RESULTS

The study cohort included 215 132 apparently healthy men, with a median age and prostate-specific antigen concentration of 59 years and 0.9 ng/mL, respectively. Prostate-specific antigen levels for the entire cohort increased with age (Pearson correlation = 0.362, P < 0.001). This relationship was most prominent in Pacific men. Similarly, the upper reference limit for the entire cohort increased with age, from 1.60 ng/mL for men aged 40-44 years to 7.61 ng/mL for those aged 75-79 years. Significant ethnic differences were present within each interval, which was most apparent in the older age groups.

CONCLUSION

Ethnic differences in age-adjusted prostate-specific antigen reference values are present in New Zealand. These need to be considered when prostate-specific antigen results are being interpreted in clinical practice.
