Addressing Systemic Racism and Racialized Violence to Reduce Firearm Injury and Mortality Inequities.

This JAMA Forum discusses systemic racism and racialized violence, promising approaches to address inequities in firearm violence, and ways to treat the trauma of gun violence.

Education in the Jim Crow South and Black-White inequities in allostatic load among older adults.

In the U.S., Black adults consistently have higher allostatic load - an indicator of physiological dysregulation - than White adults. Education is considered a likely mechanism given racial differences in attainment, but evidence is mixed. This may be due, in part, to data limitations that have made it difficult for scholars to account for the structurally rooted systemic racism that shaped the U.S. education system and led to large racial inequities in school term length and school attendance among older adults who grew up in the Jim Crow South. Our study addresses this limitation by linking historical data on Black and White segregated school systems in the U.S. South from 1919 to 1954 to the Health and Retirement Study (HRS) to determine if a new measure of educational attainment that accounts for structural racism that led to differences in the number of school days attended by Black and White students across years and states better explains Black-White inequities in allostatic load among older adults who attended school during Jim Crow. We restrict our sample to HRS respondents racialized as White or Black, who resided in the South when they were school-aged, completed primary/secondary school between 1919 and 1954, and provided a measure of allostatic load (n = 1932). We find that our new measure of schooling - duration in school - reduced the Black-White inequity in allostatic load more so than self-reported years of schooling whether we measured allostatic load continuously (34% vs 16%) or categorically (45% vs 20%). Our findings highlight the importance of identifying and using historically informed measures of schooling that account for structurally rooted systemic racism when trying to understand how education shapes the health of individuals racialized as Black in the United States.

Weathering in Detroit: Place, Race, Ethnicity, and Poverty as Conceptually Fluctuating Social Constructs Shaping Variation in Allostatic Load.

Policy Points Despite 30 years of attention to eliminating population health inequity, it remains entrenched, calling for new approaches. Targeted universalism, wellness-based local development, and Jedi Public Health approaches that are community informed, evidence based, and focused on improving everyday settings and diverse lived experiences are important policy directions. State and federal revenue transfers are necessary to mitigate the harms of austerity and assure greater equity in fiscal and population health in places like Detroit, Michigan. CONTEXT: US population health inequity remains entrenched, despite mandates to eliminate it. To promote a public health approach of consequence in this domain, stakeholders call for moving from risk-factor epidemiology toward consideration of dynamic local variations in the physiological impacts of structured lived experience. METHODS: Using a community-based, participatory research approach, we collected and analyzed a unique data set of 239 black, white, and Mexican adults from a stratified, multistage probability sample of three Detroit, Michigan, neighborhoods. We drew venous blood, collected saliva, took anthropometric measurements, and assayed specimens to measure allostatic load (AL), an indicator of stress-mediated biological dysregulation, linking participants' AL scores and survey responses. In a series of nested Poisson models, we regressed AL on socioeconomic, psychosocial, neighborhood, and behavioral stressors to test the hypothesis that race/ethnicity and poverty-to-income ratio (PIR) are conceptually fluctuating variables whose impacts on AL are sensitive to structured lived experience. FINDINGS: White and Mexican Detroit participants with PIR < 1 have higher AL than counterparts nationally; black participants in Detroit and nationwide had comparable AL. Within Detroit, disparities by PIR were higher in whites than blacks, with no significant difference by PIR in Mexicans. The size of estimated effects of having PIR < 1 for whites is 58 percentage points greater than that of Mexicans and twice that of blacks. CONCLUSIONS: Structurally rooted unobserved heterogeneity bias threatens the validity of independent main effects interpretations of associations between race/ethnicity, socioeconomic characteristics, or place and health. One-size-fits-all analytic or policy models developed from the perspective of the dominant social group insufficiently address the experiences of diverse populations in specific settings and historical moments; nor do they recognize culturally mediated protective resources residents may have developed against material and psychosocial hardship.

Addressing health inequalities in diverse, rural communities: An unmet need.

Research on rural health needs to represent the diverse demographics of these regions by carefully considering the distinct characteristics, inequities, and stressors occurring in rural communities. Drawing from our own findings and other empirical investigations examining diverse rural communities, we propose several considerations to guide future endeavors toward more inclusive rural health research. These include population-health assessment tools that consider minority stress and intervention strategies designed to reflect both the environmental and socio-cultural contexts of rural residents.

Jedi Public Health: Co-creating an Identity-Safe Culture to Promote Health Equity.

The extent to which socially-assigned and culturally mediated social identity affects health depends on contingencies of social identity that vary across and within populations in day-to-day life. These contingencies are structurally rooted and health damaging inasmuch as they activate physiological stress responses. They also have adverse effects on cognition and emotion, undermining self-confidence and diminishing academic performance. This impact reduces opportunities for social mobility, while ensuring those who "beat the odds" pay a physical price for their positive efforts. Recent applications of social identity theory toward closing racial, ethnic, and gender academic achievement gaps through changing features of educational settings, rather than individual students, have proved fruitful. We sought to integrate this evidence with growing social epidemiological evidence that structurally-rooted biopsychosocial processes have population health effects. We explicate an emergent framework, Jedi Public Health (JPH). JPH focuses on changing features of settings in everyday life, rather than individuals, to promote population health equity, a high priority, yet, elusive national public health objective. We call for an expansion and, in some ways, a re-orienting of efforts to eliminate population health inequity. Policies and interventions to remove and replace discrediting cues in everyday settings hold promise for disrupting the repeated physiological stress process activation that fuels population health inequities with potentially wide application.

Race-Ethnicity, Poverty, Urban Stressors, and Telomere Length in a Detroit Community-based Sample.

Residents of distressed urban areas suffer early aging-related disease and excess mortality. Using a community-based participatory research approach in a collaboration between social researchers and cellular biologists, we collected a unique data set of 239 black, white, or Mexican adults from a stratified, multistage probability sample of three Detroit neighborhoods. We drew venous blood and measured telomere length (TL), an indicator of stress-mediated biological aging, linking respondents' TL to their community survey responses. We regressed TL on socioeconomic, psychosocial, neighborhood, and behavioral stressors, hypothesizing and finding an interaction between poverty and racial-ethnic group. Poor whites had shorter TL than nonpoor whites; poor and nonpoor blacks had equivalent TL; and poor Mexicans had longer TL than nonpoor Mexicans. Findings suggest unobserved heterogeneity bias is an important threat to the validity of estimates of TL differences by race-ethnicity. They point to health impacts of social identity as contingent, the products of structurally rooted biopsychosocial processes.

The role of socioeconomic factors in Black-White disparities in preterm birth.

OBJECTIVES: We investigated the role of socioeconomic factors in Black-White disparities in preterm birth (PTB). METHODS: We used the population-based California Maternal and Infant Health Assessment survey and birth certificate data on 10 400 US-born Black and White California residents who gave birth during 2003 to 2010 to examine rates and relative likelihoods of PTB among Black versus White women, with adjustment for multiple socioeconomic factors and covariables. RESULTS: Greater socioeconomic advantage was generally associated with lower PTB rates among White but not Black women. There were no significant Black-White disparities within the most socioeconomically disadvantaged subgroups; Black-White disparities were seen only within more advantaged subgroups. CONCLUSIONS: Socioeconomic factors play an important but complex role in PTB disparities. The absence of Black-White disparities in PTB within certain socioeconomic subgroups, alongside substantial disparities within others, suggests that social factors moderate the disparity. Further research should explore social factors suggested by the literature-including life course socioeconomic experiences and racism-related stress, and the biological pathways through which they operate-as potential contributors to PTB among Black and White women with different levels of social advantage.

Sociocultural and socioeconomic influences on type 2 diabetes risk in overweight/obese African-American and Latino-American children and adolescents.

PURPOSE: It is unclear whether sociocultural and socioeconomic factors are directly linked to type 2 diabetes risk in overweight/obese ethnic minority children and adolescents. This study examines the relationships between sociocultural orientation, household social position, and type 2 diabetes risk in overweight/obese African-American (n = 43) and Latino-American (n = 113) children and adolescents. METHODS: Sociocultural orientation was assessed using the Acculturation, Habits, and Interests Multicultural Scale for Adolescents (AHIMSA) questionnaire. Household social position was calculated using the Hollingshead Two-Factor Index of Social Position. Insulin sensitivity (SI), acute insulin response (AIRG) and disposition index (DI) were derived from a frequently sampled intravenous glucose tolerance test (FSIGT). The relationships between AHIMSA subscales (i.e., integration, assimilation, separation, and marginalization), household social position and FSIGT parameters were assessed using multiple linear regression. RESULTS: For African-Americans, integration (integrating their family's culture with those of mainstream white-American culture) was positively associated with AIRG (ß = 0.27 ± 0.09, r = 0.48, P < 0.01) and DI (ß = 0.28 ± 0.09, r = 0.55, P < 0.01). For Latino-Americans, household social position was inversely associated with AIRG (ß = -0.010 ± 0.004, r = -0.19, P = 0.02) and DI (ß = -20.44 ± 7.50, r = -0.27, P < 0.01). CONCLUSIONS: Sociocultural orientation and household social position play distinct and opposing roles in shaping type 2 diabetes risk in African-American and Latino-American children and adolescents.

Recommendations for including multiple symptoms as endpoints in cancer clinical trials: a report from the ASCPRO (Assessing the Symptoms of Cancer Using Patient-Reported Outcomes) Multisymptom Task Force.

The multiple symptoms arising from cancer and its treatment impose significant distress for patients. However, in clinical research, there is no agreed-upon way of assessing and presenting the effects of treatment on multiple symptoms, as either individual scores or a composite score. The ASCPRO (Assessing the Symptoms of Cancer Using Patient-Reported Outcomes) Multisymptom Task Force was established to make recommendations about measuring multiple symptoms as outcomes in cancer clinical trials. The Multisymptom Task Force addressed how to choose the symptoms to be assessed and how multiple individual symptom scores or composite scores of several symptoms might be used as clinical trial outcomes. Consensus was reached on a definition of a multisymptom outcome, the problem of source attribution, and the need for a hypothesis-driven conceptual framework to measure multisymptom outcomes. Validated single-item and multi-item measures currently available or that can be easily generated for oncology use were deemed sufficient for measuring multiple symptoms. The relative value of a composite score versus a set of individual symptom scores was discussed, along with issues in developing and deploying such a composite measure. The results indicated that more research on combining scores of different symptoms is needed. Symptom data should be a required component of cancer clinical trials. Patient-reported symptoms provide a unique patient perspective on treatment benefit and risk that goes beyond clinician-reported adverse events. A representation of changes in multiple symptoms would clarify the impact of treatment and enhance the interpretation of cancer clinical trials for clinicians, patients, and those who make health care policy.

Race/ethnicity, socioeconomic characteristics, coethnic social ties, and health: evidence from the national Jewish population survey.

OBJECTIVES: We explored whether a White ethnic group with a history of structural disadvantage, Jewish Americans, shows evidence of continuing health impact independent of socioeconomic position (SEP), whether coethnic social ties appear health protective, and whether the strength of any protection varies by SEP. METHODS: In a series of ordered logistic regressions, we analyzed data from the National Jewish Population Survey, 2000-2001, regressing self-rated health on race/ethnicity, education, and income for US Blacks, Jews, and other Whites and, for Jews alone, indicators of coethnic social ties. RESULTS: controlling for SEP indicators, the self-rated health of Jews converged with that of Blacks and was significantly worse than that of other Whites. Access to coethnic social ties was associated with better self-rated health among Jews, with the strongest estimated association among those of lower SEP. CONCLUSIONS: The finding that a White ethnic group with a favorable socioeconomic profile reported significantly worse health than did other Whites, after controlling for SEP, calls for better understanding of the complex interplay of cultural, psychosocial, and socioeconomic resources in shaping population health.

Do US Black Women Experience Stress-Related Accelerated Biological Aging?: A Novel Theory and First Population-Based Test of Black-White Differences in Telomere Length.

We hypothesize that black women experience accelerated biological aging in response to repeated or prolonged adaptation to subjective and objective stressors. Drawing on stress physiology and ethnographic, social science, and public health literature, we lay out the rationale for this hypothesis. We also perform a first population-based test of its plausibility, focusing on telomere length, a biomeasure of aging that may be shortened by stressors. Analyzing data from the Study of Women's Health Across the Nation (SWAN), we estimate that at ages 49-55, black women are 7.5 years biologically "older" than white women. Indicators of perceived stress and poverty account for 27% of this difference. Data limitations preclude assessing objective stressors and also result in imprecise estimates, limiting our ability to draw firm inferences. Further investigation of black-white differences in telomere length using large-population-based samples of broad age range and with detailed measures of environmental stressors is merited.

Epidemiologic study on survival of chronic myeloid leukemia and Ph(+) acute lymphoblastic leukemia patients with BCR-ABL T315I mutation.

The BCR-ABL T315I mutation represents a major mechanism of resistance to tyrosine kinase inhibitors (TKIs). The objectives of this retrospective observational study were to estimate overall and progression-free survival for chronic myeloid leukemia in chronic-phase (CP), accelerated-phase (AP), or blastic-phase (BP) and Philadelphia chromosome-positive (Ph)(+) acute lymphoblastic leukemia (ALL) patients with T315I mutation. Medical records of 222 patients from 9 countries were reviewed; data were analyzed using log-rank tests and Cox proportional hazard models. Median age at T315I mutation detection was 54 years; 57% cases were men. Median time between TKI treatment initiation and T315I mutation detection was 29.2, 15.4, 5.8, and 9.1 months, respectively, for CP, AP, BP, and Ph(+) ALL patients. After T315I mutation detection, second-generation TKIs were used in 56% of cases, hydroxyurea in 39%, imatinib in 35%, cytarabine in 26%, MK-0457 in 11%, stem cell transplantation in 17%, and interferon-alpha in 6% of cases. Median overall survival from T315I mutation detection was 22.4, 28.4, 4.0, and 4.9 months, and median progression-free survival was 11.5, 22.2, 1.8, and 2.5 months, respectively, for CP, AP, BP, and Ph(+) ALL patients. These results confirm that survival of patients harboring a T315I mutation is dependent on disease phase at the time of mutation detection.

Stress, Allostatic Load and Health of Mexican Immigrants.

OBJECTIVE: To assess whether the cumulative impact of exposure to repeated or chronic stressors as measured by allostatic load, contributes to the "unhealthy assimilation" effects often observed for immigrants with time in the United States. METHODS: We analyzed data from the National Health and Nutrition Examination Survey, 1988-1994, to estimate multivariate logistic regression models of the odds of having a high allostatic load score among Mexican immigrants, stratified by adult age group, according to length of residence in US, controlling for demographic, socioeconomic, and health input covariates. RESULTS: Estimates indicate that 45-60 year old Mexican immigrants have lower allostatic load scores upon arrival than US-born Mexican Americans, non-Hispanic whites, and non-Hispanic Blacks, and that this health advantage is attenuated with duration of residence in the US. CONCLUSIONS: The findings of our analysis are consistent with the hypothesis that repeated or chronic physiological adaptation to stressors is one contributor to the "unhealthy assimilation" effect observed for Mexican immigrants.

The GRID-HAMD: standardization of the Hamilton Depression Rating Scale.

This report describes the GRID-Hamilton Depression Rating Scale (GRID-HAMD), an improved version of the Hamilton Depression Rating Scale that was developed through a broad-based international consensus process. The GRID-HAMD separates the frequency of the symptom from its intensity for most items, refines several problematic anchors, and integrates both a structured interview guide and consensus-derived conventions for all items. Usability was established in a small three-site sample of convenience, evaluating 29 outpatients, with most evaluators finding the scale easy to use. Test-retest (4-week) and interrater reliability were established in 34 adult outpatients with major depressive disorder, as part of an ongoing clinical trial. In a separate study, interrater reliability was found to be superior to the Guy version of the HAMD, and as good as the Structured Interview Guide for the Hamilton Depression Rating Scale (SIGH-D), across 30 interview pairs. Finally, using the SIGH-D as the criterion standard, the GRID-HAMD demonstrated high concurrent validity. Overall, these data suggest that the GRID-HAMD is an improvement over the original Guy version as well as the SIGH-D in its incorporation of innovative features and preservation of high reliability and validity.

Longitudinal evaluation of interobserver and intraobserver agreement of cervical intraepithelial neoplasia diagnosis among an experienced panel of gynecologic pathologists.

Histologic diagnoses of cervical intraepithelial neoplasia grades 2 and 3 (CIN 2/3) are the key end points in clinical trials that evaluate the efficacy of a prophylactic quadrivalent human papillomavirus vaccine against cervical cancer. Adjudication of end points uses a panel of 4 pathologists. Quality control slides (n=185) from a nonclinical trial study with preestablished gold standard CIN diagnoses were used to characterize the panel's agreement on CIN diagnoses and monitor performance longitudinally. At 3-month intervals over 2 years, 1 of 6 different batches of quality control slides (n=30-31) was included with clinical trial slides for independent review by each of the 4 panelists. Unweighted kappas (kappa) were estimated within each panelist pair by dichotomizing the diagnoses as CIN+ versus non-CIN+ (including normal, unsatisfactory, and atypical immature metaplasia) or CIN 2/3+ versus non-CIN 2/3+ (including normal, unsatisfactory, atypical immature metaplasia, and CIN 1). Quadratic weighted kappa was calculated within each panelist pair using 4 diagnostic categories: normal, CIN 1, CIN 2, and CIN 3 or worse. Substantial interobserver agreement was observed (weighted kappa=0.765 to 0.865). Agreement with weighted kappa=0.779 to 0.887 was observed between the individual panelists and the gold standard, which is almost perfect agreement by Landis-defined categories. Intraobserver agreement was very high (weighted kappa=0.756 to 0.883). Some fluctuation in intraobserver and interobserver agreement was observed over the study period but there was no decreasing time trend. These data indicate that the interpretation of histologic end points used in the quadrivalent vaccine clinical trial program is highly valid and reliable.

Nonsteroidal anti-inflammatory drugs and risk of prostate cancer in the Baltimore Longitudinal Study of Aging.

BACKGROUND: Laboratory and epidemiologic studies suggest that aspirin and nonaspirin nonsteroidal anti-inflammatory drugs (NSAID) reduce the risk of cancer, possibly via inhibition of the cyclooxygenase enzymes. We evaluated the association of aspirin and nonaspirin NSAIDs with subsequent prostate cancer in a prospective study. We also assessed whether use of these drugs influences serum prostate-specific antigen (PSA) concentration. METHODS: Participants were 1,244 male members of the Baltimore Longitudinal Study of Aging. Use of prescription and over-the-counter drugs was collected by questionnaire and interview at multiple study visits. One hundred forty-one prostate cancer cases diagnosed between 1980 and May 2004 were confirmed by medical record review. We used Cox proportional hazards regression to estimate the rate ratio (RR) of prostate cancer updating drug use over time and taking into account age and year. We used generalized estimating equations to calculate age-adjusted geometric mean PSA concentration by aspirin or nonaspirin NSAIDs use among 933 of the men without prostate cancer, for whom 3,749 PSA measurements in archived sera had been done previously. RESULTS: On 46.0% and 21.5% of the visits, current use of aspirin or nonaspirin NSAIDs (mostly ibuprofen) was reported, respectively. The RRs of prostate cancer comparing ever to never use were 0.76 [95% confidence interval (95% CI), 0.54-1.07] for aspirin, 0.79 (95% CI, 0.54-1.16) for nonaspirin NSAIDs, and 0.71 (95% CI, 0.49-1.02) for either medication. The association for ever use of either aspirin or nonaspirin NSAIDs was suggestively more pronounced in men <70 years (RR, 0.54; 95% CI, 0.27-1.03) than in men >/=70 years (RR, 0.78; 95% CI, 0.50-1.22; P(interaction) = 0.73). The RR for current use of either drug was attenuated relative to ever use. Mean PSA concentration did not differ between users and nonusers of either aspirin or nonaspirin NSAIDs (1.01 versus 0.98 ng/mL, P = 0.56). CONCLUSION: In this prospective study, men, in particular younger men, who had ever used aspirin or nonaspirin NSAIDs had a modest nonstatistically significant lower risk of prostate cancer. The modest inverse association was unlikely due to detection bias that might have resulted if anti-inflammatory drugs had influenced serum PSA concentration.

Familial aggregation of bothersome benign prostatic hyperplasia symptoms.

OBJECTIVES: To evaluate familial aggregation and the mode of inheritance of bothersome benign prostatic hyperplasia (BPH). METHODS: During an extension of the North American Finasteride Trial, 301 of 895 patients and 158 spousal controls completed a family history questionnaire. Segregation analysis was performed to examine the mode of inheritance in first-degree relatives of the 301 probands. RESULTS: The lifetime cumulative probability of bothersome BPH was similar in relatives of those with BPH (0.35; 95% confidence interval [CI] 0.28 to 0.44) and spousal controls (0.36; 95% CI 0.22 to 0.56), but the age of onset was significantly earlier in relatives of cases than controls (P = 0.001). Fathers of those with BPH had a significantly elevated risk of bothersome BPH (unadjusted odds ratio [OR] 2.1; 95% CI 1.2 to 3.8) and brothers had a significantly elevated risk of both bothersome BPH (OR 3.5; 95% CI 1.7 to 7.3) and transurethral resection of the prostate (OR 3.6; 95% CI 1.4 to 8.8). After adjusting for family size, the risk of bothersome BPH increased approximately twofold with each additional affected first-degree relative (0 relatives, OR 1.0; 1 relative, OR 1.7; 2 relatives, OR 4.7). Segregation analysis suggested a rare autosomal codominant allele (frequency 0.0004). CONCLUSIONS: These findings confirm previous findings that family history and early age of onset are associated with an increased risk of BPH and that the most likely mode of inheritance is autosomal dominant or codominant. Bothersome BPH appears to have a weaker genetic component than more restrictive definitions of hereditary BPH. Thus, linkage studies are more likely to be successful if they focus on stricter definitions of hereditary BPH (eg, early onset, large volume, strong family history) rather than symptomatic or clinical BPH.

A randomized, placebo controlled, multicenter study to evaluate the safety and efficacy of rofecoxib in the treatment of chronic nonbacterial prostatitis.

PURPOSE: We determine the effects of treatment with rofecoxib and placebo in patients with chronic prostatitis. MATERIALS AND METHODS: Patients diagnosed with chronic nonbacterial prostatitis were randomized to 6 weeks of 25 or 50 mg., rofecoxib or placebo in a double-blind multicenter study with a 1-week run in of placebo. End points included the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) (average pain score item 4 primary end point), and patient global assessment questions of pain, disease activity and response to therapy. RESULTS: A total of 161 patients were randomized in the study. The NIH-CPSI total, domain and pain scores significantly decreased from baseline in all groups and, although the mean scores numerically favored the rofecoxib groups, the difference was not significantly different among groups. There was a trend for the percentage of patients with a 25% (or 6 point) improvement in total score being superior on rofecoxib versus placebo with the difference being significantly different (p <0.05) for the 50 mg. rofecoxib group. Patient global assessment of pain, response to therapy and disease activity also favored rofecoxib over placebo (p <0.05, p = 0.07, p = 0.06, respectively). Of the patients 79% on 50 mg. rofecoxib versus 59% on placebo reported no or mild pain, and 56% of patients on 50 mg. rofecoxib versus 27% on placebo experienced significant improvement in quality of life (p <0.005). Rofecoxib was generally well tolerated. CONCLUSIONS: To our knowledge this study is the first to evaluate rofecoxib versus placebo in patients with prostatitis and the first large multicenter treatment study to use the NIH-CPSI. Subjective assessment with patient global questions may be more sensitive to change than the NIH-CPSI and, therefore, may be a better tool to use in future therapeutic trials. Although 6 weeks of rofecoxib treatment appear to benefit many men diagnosed with chronic prostatitis/chronic pelvic pain syndrome further studies are needed.
