6089 Background: Although mortality among black women diagnosed with uterine cancer is higher than in white women, the reason for this difference is not completely understood. We proposed to investigate the differences in the incidence and presentation of uterine cancer histology among black women compared to white women. Methods: Data were obtained from the United States Cancer Statistics (USCS) and the National Cancer Database (NCDB) between 2004 and 2016. Chi-squared tests were used for statistical analyses. Results: Of 488,811 patients with uterine cancer, 411,904 (84.3%) were white and 51,093 (10.5%) were black. Based on USCS data, the incidence of endometrioid carcinoma in white women was 19.63 (per 100,000 per year) compared to 12.53 in black women. However, the incidence of high-risk histologies was higher in black women, particularly for serous tumors (3.32 vs. 1.29), clear cell tumors (0.59 vs. 0.31), carcinosarcoma (2.88 vs. 1.05), and leiomyosarcoma (1.02 vs. 0.48). Using the NCDB database, we evaluated the proportion of these histologies based on race. Compared to white women, black women have a higher proportion of serous (14.2% vs. 5.6%), clear cell (2.4% vs. 1.3%), carcinosarcoma (12.3% vs. 4.5%), and leiomyosarcoma (4.3% vs. 1.7%). black women were less likely to have endometrioid (52.7% vs. 75.9%) and mucinous (0.4% vs. 0.8%) tumors. In addition, black women were more likely to have stage III or IV disease at presentation when all histological subtypes were combined (22.8% vs. 17.7%). However, of those with endometrioid and grade 1 tumors, black women did not have more advanced stage at presentation compared to white women (3.8% vs. 4.7%). Conclusions: Compared to white women, black women are more likely to be diagnosed with serous, clear cell, carcinosarcoma, and leiomyosarcomas at a more advanced stage upon presentation, but they are less likely to have endometrioid tumors. More research is needed to understand why this disparity exists.

6550 Background: Despite similar incidence rates of uterine cancer (UC) in Black and White women, the former have worse prognosis and survival. Absence of denominator correction for UC hysterectomy (prevalence varies within the United States [US] by race/region) may underestimate incidence. The objective of this study is to compare treatment and survival of patients with UC by race in a large, contemporary, population-based study with at least 5 years of follow-up. Methods: With the latest available data from the Surveillance, Epidemiology, and End Results database, comparisons between Black and White patients were made using chi-square and Mann-Whitney tests. Cox proportional hazards regression estimated the adjusted risk of mortality by including age at diagnosis, race, US region, tumor histology/stage/grade, and receipt of hysterectomy as covariates. Results: A total of 105,036 women (11,028 Black and 94,008 White) newly diagnosed with UC in 2000-2013 and followed through 2018 were identified. Median age at diagnosis was 62 years, and more patients in the South were Black (41% vs 17%, P<.0001). Higher rates of type 2 (15% vs 6%), late-stage (44% vs 28%), and high-grade (48% vs 25%) tumors at diagnosis were also found in Black women (all Ps<.0001; Table). Compared with White women, Black women had lower 5-year survival rate (18% vs 37%, P<.0001), shorter survival (median 49 vs 78 months, P<.0001), and higher adjusted mortality risk (hazard ratio [HR]: 1.3, 95% CI: [1.3, 1.4], P<.0001). Lack or unknown status of hysterectomy was also associated with higher death risk (HR: 3.6, 95% CI: [3.4, 3.9], P<.0001). Conclusions: Correcting for hysterectomy attenuates racial disparity in incidence; however, black women have inferior outcomes primarily due to increased aggressive histology, late-stage, and high-grade tumors as well as decreased use of hysterectomy. Underestimation of at-risk populations may be misdirecting cancer control efforts, highlighting the importance of accurate reporting to inform potential treatment adaptations. Next steps are to assess cancer-specific mortality with Fine-Gray competing risk models.[Table: see text]

Racial and ethnic differences in breast cancer occur by race/ethnicity in both incidence and mortality rates. Women of lower socioeconomic status likewise have poorer outcomes. When race alone is considered, incidence rates in the United States are highest among White women (130.8 per 100,000), with Black women close behind (126.7 per 100,000). Incidence is lowest among Asian/Pacific Islander women, at 93.2 per 100,000. Mortality differences are more pronounced, with Black women 40% more likely to die from breast cancer than White women (28.4 per 100,000 and 20.3 per 100,000, respectively). Mortality rates for Asian/Pacific Islander women (11.5 per 100,000) are far lower than for Black and White women. When age is considered, additional differences between Black and White women appear, in part accounted for by types of breast cancer experienced. Women of other racial/ethnic groups and socioeconomic status have received less scientific attention. In this article, we provide a brief overview of the evidence for social determinants of breast cancer and argue that the current reliance on race over racism and ethnicity contributes to our inability to eliminate breast cancer disparities in the United States and elsewhere in the world. We suggest alternatives to the current approach to research in breast cancer disparities.

Objective: Improvements in the Black- White difference in life expectancy have been attributed to improved diagnosis and treatment of cardiovascular diseases and declines in cardiovascular disease mortal­ity. However, it is unclear whether race differences in total cardiovascular risk and the prevalence of cardiovascular risk factors have improved in the United States since the 1990s.Design: Serial cross-sectional design.Setting: Data from the 1988-1994, 1999- 2002, and 2009-2012 National Health and Nutrition Examination Survey (NHANES).Methods: We estimated total cardiovascu­lar risk levels, the prevalence of high-risk cardiovascular risk factors and the use of antihypertensive and lipid-lowering drugs among US Black and White men and women to determine whether differential changes occurred from 1990-2010.Results: Total cardiovascular risk declined for all races from 1990-2010. The Black- White difference was only significant in 2000 and sex-specific analyses showed that trends seen in the total population were driven by changes among women. Black and White men did not differ in risk at any time during this period. Conversely, Black women had significantly higher risk than White women in 1990 and 2000; this dif­ference was eliminated by 2010. Improved diagnosis and treatment of high blood pres­sure and high cholesterol reduced risk in the total population; improved blood pressure and lipid profiles among Black women and increasing obesity prevalence among White women specifically contributed to the nar­rowing of the Black-White difference in risk among women.Conclusion: Cardiovascular risk and racial disparities in risk declined among US Whites and Blacks due to greater use and effective­ness of lipid-lowering and antihypertensive medications.Ethn Dis. 2019;29(4):587-598; doi:10.18865/ed.29.4.587

The authors conducted a survival analysis to determine the effect of poverty on mortality in a national sample of blacks and whites, 25 to 74 years of age (the first National Health and Nutrition Examination Survey (NHANES-1) and NHANES-I Epidemiologic Follow-up Study). They estimated the proportion of mortality associated with poverty during 1971–1984 and in 1991 by calculating population attributable risk and assessed confounding by major known risk factors (e.g., smoking, cholesterol levels, and physical inactivity). In 1973, 6.0 percent of U.S. mortality among black and white persons 25 to 74 years of age was attributable to poverty; in 1991, the proportion was 5.9 percent. In 1991, rates of mortality attributable to poverty were lowest for white women, 2.2 times as high for white men, 8.6 times as high for black men, and 3.6 times as high for black women. Adjustment for all these potential confounders combined had little effect on the hazard ratio among men, but reduced the effect of poverty on mortality among women by 42 percent. The proportion of mortality attributable to poverty among U.S. black and white adults has changed only minimally in recent decades. The effect of poverty on mortality must be largely explained by conditions other than commonly recognized risk factors.

Pregnancy-associated femicide accounts for a mortality burden at least as high as any of the leading specific obstetric causes of maternal mortality, and intimate partners are the most common perpetrators of these homicides. This study examined pregnancy-associated and non-pregnancy-associated intimate partner homicide (IPH) victimization among racial/ethnic minority women relative to their non-minority counterparts using several sources of state-level data from 2003 through 2017. Data regarding partner homicide victimization came from the National Violent Death Reporting System, natality data were obtained from the Centers for Disease Control and Prevention’s National Center for Health Statistics, and relevant sociodemographic information was obtained from the U.S. Census Bureau. Findings indicated that pregnancy and racial/ethnic minority status were each associated with increased risk for partner homicide victimization. Although rates of non-pregnancy-associated IPH victimization were similar between Black and White women, significant differences emerged when limited to pregnancy-associated IPH such that Black women evidenced pregnancy-associated IPH rates more than threefold higher than that observed among White and Hispanic women. Relatedly, the largest intraracial discrepancies between pregnant and non-pregnant women emerged among Black women, who experienced pregnancy-associated IPH victimization at a rate 8.1 times greater than their non-pregnant peers. These findings indicate that the racial disparities in IPH victimization in the United States observed in prior research might be driven primarily by the pronounced differences among the pregnant subset of these populations.

In The Growth of Incarceration in the United States, the National Research Council documents the large and persistent racial disparities in imprisonment that accompanied the more than quadrupling of the U.S. incarceration rate since the 1980s. Largely unnoticed by policy makers and opinion leaders in recent years is an unprecedented decrease in the number of African American women incarcerated at the same time that the number of white women in prison has grown to new heights. The result of these recent changes is a near convergence in black-white female incarceration rates from 2000 to 2016. In some states, the changes occurred abruptly and almost instantaneously. In other states, the convergence has been gradual. We find that changes in the population composition—the fraction of the population that is black—was the major contributor to the decline in the disparity among women. We also find that race-specific differences in drug overdose deaths stemming from the recent increases in opioid use lowered the disparity by increasing the white female imprisonment rate and lowering it for black women.

Although the United States spends more on health care than comparable nations, many Americans suffer from poor health. Many factors are emphasized as being important for improved health outcomes, including social and economic indicators, living and working conditions, and individual-level behavior. However, I argue the overwhelming attention to male health outcomes—compared to female health outcomes—and focus on factors that are “traditionally understood” as important in shaping health are two limitations of existing health-related research. I adopt an innovative approach that combines the theory of representative bureaucracy, gender concordance, and symbolic representation to argue that increase in female physicians contribute to improved female health outcomes. Using an originally collected dataset that contains information on female physicians, health outcomes, and state and individual-level factors, I study how female physicians influence the health outcomes of non-Hispanic White women, non-Hispanic Black women, and Latinas in the United States from 2000 to 2012. The findings suggest female physicians contribute to improved health outcomes for non-Hispanic White women and non-Hispanic Black women, but not Latinas. Supplemental Analysis bolsters confidence that the findings are not the result of increased access to health care professionals. This study highlights the importance of applying the theory of representative bureaucracy and symbolic representation to health care, the promise of greater female representation in health, and the insight gleaned from incorporating intersectionality in public administration research.

e12599 Background: Higher prevalence of triple negative breast cancer (TNBC) in black women with associated poor outcomes due to various disparities is well documented within a single state. We examine multiple states to better understand the state effect on such differences in incidence and prevalence of TNBC in black women. Methods: Female patients of ages 19 years old and above with breast cancer from the Surveillance, Epidemiology and End Results (SEER) Program across 13 states (608 counties) from 2015 (n = 66,444) and 2016 (n = 66,122) were examined. The relationships between the proportion of black and white women and the rate of patients with different tumor subtypes (luminal A, luminal B, HR-HER2+, and triple negative) were examined at the county level using ordinary least-square regression models. In parallel, due to consideration of various state-specific healthcare policies, socio-cultural norms, and socio-economic disparities, multi-level regression models were applied to examine the nested, random effect of each state on TNBC prevalence in each county. Bonferroni correction was applied to reduce the Type I error caused by repeated use of the same variables in multiple tests. Results: The baseline breast cancer rates between black and white women were similar in the population (0.171% for black and 0.168% for white). Consistent to previous studies, we demonstrate a significant positive correlation (p < 0.001) in TNBC in black females in both years. Surprisingly, when accounted for the random effects on states, 38.2% (2015) and 34.3% (2016) increase in incidence of TNBC in black females were seen, suggestive of state-specific disparity affecting race-specific health. In 2015, other subtypes of breast cancer in both black and white females did not result in significant relationship. Interestingly, in 2016, there was a significant relationship seen between the TNBC rate in white females and the white female population rate only after adjusting for the state effect (p = 0.026). This indicates the impact of non-biological factors such as state-wide health policies. Additionally, HR-HER2+ black females had a significant relationship against respective population rate only after adjusting for the state effect as well (p = 0.0394). For luminal A white females, a 15% decrease in incidence was seen after adjusting for state effect (p = 0.0424). Conclusions: This is the first known across-state examination of breast cancer subtypes by race with random effects on state. This study shows the role of state-specific factors affecting incidence in black and white females and potentially indicates the importance of state-level management for breast cancer on health disparities in addition to race-driven effects. Further studies are needed to elucidate comparable differences between states affecting the rates of various subtypes of breast cancer and thus health outcomes.

Background: Recent evidence suggests that racial differences in circulating levels of free or bioavailable 25(OH)D rather than total 25(OH)D may explain the apparent racial disparities in cardiovascular disease(CVD).However, few prospective studies have directly tested this hypothesis. Objective: Our study prospectively examined black white differences in the associations of total, free, and bioavailable 25(OH)D, vitamin D binding protein (VDBP), and parathyroid hormone (PTH) levels at baseline with incident CVD in a large, multi-ethnic, geographically diverse cohort of postmenopausal women. Method: We conducted a case-cohort study among 79,705 black and non-Hispanic white postmenopausal women aged 50 to 79 years and free of CVD at baseline in the Women’s Health Initiative Observational Study (WHI-OS). We included a randomly chosen subcohort of 1,300 black and 1,500 white noncases at baseline and a total of 550 black and 1,500 white women who developed incident CVD during the follow up. We directly measured circulating levels of total 25(OH)D, VDBP (monoclonal antibody assay), albumin, and PTH and calculated free and bioavailable vitamin D levels. Weighted Cox proportional hazards models were used while adjusting for known CVD risk factors. Results: At baseline, white women had higher mean levels of total 25(OH)D and VDBP and lower mean levels of free and bioavailable 25(OH)D and PTH than black women (all P values < 0.0001). White cases had lower levels of total 25(OH)D and VDBP and higher levels of PTH than white noncases, while black cases had higher levels of PTH than black noncases (all P values < 0.05). There was a trend toward an increased CVD risk associated with low total 25(OH)D and VDBP levels or elevated PTH levels in both US black and white women. In the multivariable analyses, the total, free, and bioavailable 25(OH)D, and VDBP were not significantly associated with CVD risk in black or white women. A statistically significant association between higher PTH levels and increased CVD risk persisted in white women, however. The multivariate-adjusted hazard ratios [HRs] comparing the extreme quartiles of PTH were 1.37 (95% CI: 1.06-1.77; P-trend=0.02) for white women and 1.12 (95% CI: 0.79-1.58; P-trend=0.37) for black women. This positive association among white women was also independent of total, free, and bioavailable 25(OH)D or VDBP. There were no significant interactions with other pre-specified factors, including BMI, season of blood draw, sunlight exposure, recreational physical activity, sitting time, or renal function. Interpretation: Findings from a large multiethnic case-cohort study of US black and white postmenopausal women do not support the notion that circulating levels of vitamin D biomarkers may explain black-white disparities in CVD but indicate that PTH excess may be an independent risk factor for CVD in white women.
