Few studies have assessed the association of resting heart rate (RHR) through young adulthood with incident hypertension by middle age. We investigated the association between RHR measured over 30 years with incident hypertension in a cohort of young Black and White men and women. A joint longitudinal time-to-event model consisting of a mixed random effects submodel, quadratic in follow-up time, and a survival submodel adjusted for confounders, was used to determine hazard ratios for a 10 bpm higher RHR. Race-sex specific effects were examined in a single joint model that included interactions of race-sex groups with longitudinal RHR. Out of 5115 participants enrolled in year 0 (1985–1986), after excluding prevalent cases of hypertension at baseline, 1615 men and 2273 women were included in the analytic cohort. Hypertension event rates per 1000 person-years were 42.5 and 25.7 in Black and White men, respectively, and 36.2 and 15.3 in Black and White women, respectively. The hazard ratios for a 10 bpm higher RHR were 1.47 (95% CI, 1.23–1.75), 1.51 (95% CI, 1.28–1.78), 1.48 (95% CI, 1.26–1.73), and 1.02, (95% CI, 0.89–1.17) for Black men, White men, White women, and Black women, respectively. Higher RHR during young adulthood is associated with a greater risk of incident hypertension by middle age. The association is similarly strong in Black men, White men, and White women, but absent in Black women, which may suggest racial differences in the effect of sympathetic nervous activity on hypertension among women.

Introduction: Since the 1980’s, length of stay (LOS) for acute MI (AMI) has declined in the US. However, little is known about trends in LOS for non-white racial groups and whether change in LOS is related to insurance type or hospital complications. Methods: We determined 22 year trends in LOS for nonfatal (definite or probable) AMI among black and white residents age 35–74 in 4 US communities (N=396,514 in 2008 population) under surveillance in the ARIC Study. Events were randomly sampled and independently validated using a standardized algorithm. All analyses accounted for sampling scheme. We excluded MI events which started after admission (n=1,677), events within 28 days for the same person (n=3,817), hospital transfers (n=571), and those with LOS=0 or LOS >66 (top 0.5% of distribution, N= 144) leaving 22,258 weighted events for analysis. The average annual change in log LOS was modeled using weighted linear regression with year as a quadratic term. All models adjusted for age and secondary models adjusted for insurance type (Medicare, Medicaid, private, or other), and complications during admission (cardiac arrest, cardiogenic shock, or heart failure). Results: The average age-adjusted LOS from 1987 to 2008 was reduced by 5 days in black men (9.5 to 4.5 days); 4.6 days in white women (9.4 to 4.8 days); 4 days in white men (8.3 to 4.3 days) and 3.6 days in black women (9.0 to 5.4 days). Between 1987 and 2008, the age-adjusted average annual percent change (with 95% CI) in LOS was largest for white men at −4.40 percent per year (−4.91, −3.89) followed by −3.89 percent (−4.52, −3.26) for white women, −3.72 percent (−4.46, −2.89) for black men, and −2.94 percent (−3.92, −1.96) for black women (see Figure). Adjustment for insurance type, and complications did not change the pattern by race and gender. Conclusions: Between 1987 and 2008, LOS for AMI declined significantly and similarly in men and women, blacks and whites. These changes appear independent of differences in insurance type and hospital complications among race-gender groups.

Visceral Adipose

Background: Higher visceral adipose tissue (VAT) volume is associated with greater risk for hypertension (HTN). Although VAT volume and prevalence of HTN vary by sex and race, the differences in VAT volumes associated with identification of individuals with prevalent HTN across these groups is unclear. Objective: To determine VAT volume cut points that maximize true positive, true negative and optimal identification of prevalent HTN and to compare the cut points across sex and race groups. Methods: Data were examined from the Coronary Artery Risk Development in Young Adults (CARDIA) study, a multi-center longitudinal study of the development of cardiovascular risk in black and white men and women ages 18-30 years at baseline. In 2010-11, the Year 25 exam was performed (43-55 years) and VAT volume (cm3) was quantified by computed tomography based on two 5 mm contiguous slices at the level of the 4th-5th lumbar vertebra (n=3,153). HTN was defined as systolic blood pressure ≥140 mmHg, diastolic blood pressure ≥90 mmHg and/or anti-hypertension medication use. Receiver operating characteristic (ROC) curve analysis was used to identify VAT volume cut points associated with true positive, true negative and optimal identification of prevalent HTN. Results: Year 25 prevalence of HTN ranged from 18.2% (white women) to 49.4% (black women); mean VAT volume ranged from 113.5 cm3 (white women) to 172.1 cm3 (white men). White males exhibited the highest VAT volumes (22-36% higher) and black women exhibited the lowest VAT volumes (3-50% lower) associated with true positive, true negative and optimal identification of HTN compared to other race/sex groups (Table 1). VAT volumes associated with HTN among black participants were generally lower than those exhibited for whites. Conclusions: Although the utility of VAT alone to identify HTN cases is modest - likely a result of unaccounted HTN confounders - these findings display the distinct race- and sex-specific differences in VAT volumes associated with prevalent HTN in middle age adults.

Introduction: To identify potential targets for eliminating disparities in cardiovascular disease outcomes, we examined race-sex differences in awareness, treatment and control of hyperlipidemia in the REGARDS cohort. Methods: REGARDS recruited 30,239 blacks and whites aged ≥45 residing in the 48 continental US between 2003-7. Baseline data were collected via telephone interviews followed by in-home visits. We categorized participants into coronary heart disease (CHD) risk groups (CHD or risk equivalent [highest risk]; Framingham Coronary Risk Score [FRS] >20%; FRS 10-20%; FRS <10%) following the 3 rd Adult Treatment Panel. Prevalence, awareness, treatment and control of hyperlipidemia were described across risk categories and race-sex groups. Multivariable models examined associations for hyperlipidemia awareness, treatment and control between race-sex groups compared with white men, adjusting for predisposing, enabling and need factors. Results: There were 11,677 individuals at highest risk, 847 with FRS >20%, 5791 with FRS 10-20%, and 10,900 with FRS<10%; 43% of white men, 29% of white women, 49% of black men and 43% of black women were in the highest risk category. More high risk whites than blacks were aware of their hyperlipidemia but treatment was 10-17% less common and control was 5-49% less common among race-sex groups compared with white men across risk categories. After multivariable adjustment, all race-sex groups relative to white men were significantly less likely to be treated or controlled, with the greatest differences for black women vs. white men (Table). Results were similar when stratified on CHD risk and area-level poverty tertile. Conclusion: Compared to white men at similar CHD risk, fewer white women, black men and especially black women who were aware of their hyperlipidemia were treated and when treated, they were less likely to achieve control, even after adjusting for factors that influence health services utilization.

Using Data

<p>A growing body of research from the United States informed by intersectionality theory indicates that racial identity, gender, and income are often entwined with one another as determinants of health in unexpectedly complex ways. Research of this kind from Canada is scarce, however. Using data pooled from ten cycles (2001- 2013) of the Canadian Community Health Survey, we regressed hypertension (HT) and diabetes (DM) on income in subsamples of Black women (n = 3,506), White women (n = 336,341), Black men (n = 2,806) and White men (n = 271,260). An increase of one decile in income was associated with lower odds of hypertension and diabetes among White men (ORHT = .98, 95% CI (.97, .99); ORDM = .93, 95% CI (.92, .94)) and White women (ORHT = .95, 95% CI (.95, .96); ORDM = .90, 95% CI (.89, .91)). In contrast, an increase of one decile in income was not associated with either health outcome among Black men (ORHT = .99, 95% CI (.92, 1.06); ORDM = .99, 95% CI (.91, 1.08)) and strongly associated with both outcomes among Black women (ORHT = .86, 95% CI (.80, .92); ORDM = .83, 95% CI (.75, .92)). Our findings highlight the complexity of the unequal distribution of hypertension and diabetes, which includes inordinately high risks of both outcomes for poor Black women and an absence of associations between income and both outcomes for Black men in Canada. These results suggest that an intersectionality framework can contribute to uncovering health inequalities in Canada.</p><p><em>Ethn Dis.</em>2017;27(4):371-378; doi:10.18865/ ed.27.4.371. </p>

Both politicians and the mass public believe that identity influences political behavior yet, political scientists have failed to fully detail how identity is salient for all political actors not just minorities and women legislators. To what extent do racial, gendered, and race/gendered identities affect the legislation decision process? To test this proposition, I examine how race and gender based identities shape the legislative decisions of Black women in comparison to White men, White women, and Black men. I find that Black men and women legislators interviewed believe that racial identity is relevant in their decision making processes, while White men and women members of the Maryland state legislature had difficulty deciding whether their identities mattered and had even more trouble articulating how or why they did. African American women legislators in Maryland articulate or describe an intersectional identity as a meaningful and significant component of their work as representatives. More specifically, Black women legislators use their identity to interpret legislation differently due to their race/gender identities.

Serum Myoglobin

Abstract A radioimmunoassay was used to study the relation of race, sex, and age to serum myoglobin concentrations in ostensibly healthy individuals: 75 white men, 76 white women, 75 black men, and 66 black women, ranging in age from 20 to 85 years. Mean serum myoglobin values were significantly higher in men than in women in both races (35 vs 31 microgram/L for whites and 44 vs 29 microgram/L for blacks). Black men had higher values than white men, but no corresponding difference was observed in the female population. Except for the group of black men, which consistently had the highest values for serum myoglobin, values were always higher for the older groups (greater than or equal to 50 years) than the younger, irrespective of race or sex. Serum myoglobin and age were significantly and directly correlated only among white men (r = 0.3408 p &lt; 0.01, n = 75). If results were expressed as a myoglobin/creatinine ratio, the distinctions by race, sex, and age were partly eliminated. Reference intervals for serum myoglobin, expressed both ways, are given for different race, sex, and age groups.

Initial Screening

Abstract We compared initial screening data of 44,149 whites (17,043 men; 27,106 women) and 26,947 blacks (9,788 men; 17,159 women) who reported no previous diagnosis of hemochromatosis or iron overload from a primary care-based sample of ~100,000 adults ≥25 years recruited from 5 Field Centers. Each underwent transferrin saturation (TfSat) and serum ferritin (SF) measurements without regard to fasting, and HFE C282Y and H63D genotyping. We observed these mean TfSat and SF values and percentages of participants with elevated biochemical measurements (TfSat >50% and SF >300 ng/mL, men; TfSat >45% and SF >200 ng/mL, women): Participants Mean % TfSat (95% CI) Elevated TfSat, % Participants Mean SF, ng/mL (95% CI) Elevated SF, % Participants White men 32.4 (32.3, 32.6) 7.05 150.9 (149.1, 152.8) 19.49 Black men 29.3 (29.1, 29.5) 4.03 178.4 (175.5, 181.3) 25.95 p Value <0.0001 <0.0001 <0.0001 <0.0001 White women 27.5 (27.3, 27.6) 6.62 63.0 (62.3, 63.7) 8.74 Black women 23.3 (23.1, 23.4) 3.04 68.3 (67.2, 69.4) 15.43 p Value <0.0001 <0.0001 <0.0001 <0.0001 In participants grouped by decade, mean TfSat was greater in white men than in black men, and in white women than in black women (all p<0.0001). Mean SF was greater in black men than in white men in all decades except 25–34 years, and in black women than in white women in decades ≥45 years. SF increased with age to ~45 years in white men and ~50 years in black men, and then decreased. In white women, SF rose with age until ~62 years and less rapidly to age ≥80. In black women, SF rose with age until ~62 years and then decreased. C282Y allele frequency was 0.0700 (95% CI: 0.0683, 0.0717) in whites and 0.0119 (0.0110, 0.0129) in blacks. H63D allele frequency was 0.1532 (0.1509, 0.1556) in whites and 0.0299 (0.0284, 0.0313) in blacks. Frequencies of genotypes with C282Y or H63D were greater in whites than in blacks (all p<0.0001). The prevalence of elevated TfSat and SF plus genotype C282Y/C282Y was 0.003 in whites and 0.00004 in blacks (p<0.0001). The prevalence of elevated TfSat and SF plus genotype C282Y/C282Y, C282Y/H63D, or H63D/H63D was 0.006 in whites and 0.0003 in blacks (p<0.0001). We conclude that: 1) the prevalence of elevated TfSat is higher in whites and the prevalence of elevated SF is higher in blacks; 2) SF levels increase with age; 3) HFE C282Y and H63D alleles occur more frequently in whites than in blacks; and 4) the prevalence of elevated TfSat and SF plus genotypes with two common HFE mutations is greater in whites than in blacks.

This study investigates the prevalence of self-reported experiences of discrimination based on sexual orientation among black and white women and men (25 to 37 years old) who are members of CARDIA, a multisite longitudinal study of cardiovascular risk factors. Among the 1,724 participants who responded to a 1989 questionnaire obtaining data on lifetime number of sexual partners and who participated in the Year 7 exam (1992–1993), which included questions about discrimination, 204 (12 percent) reported having at least one same-sex sexual partner: 27 (7 percent) of the 412 black women, 13 (6 percent) of the 221 black men, 87 (14 percent) of the 619 white women, and 77 (16 percent) of the 472 white men. Among these four groups, 33, 39, 52, and 56 percent, respectively, reported having experienced discrimination based on sexual orientation. Additionally, 85 percent of the black women and 77 percent of the black men reported having experienced racial discrimination, and 89 percent of the black women and 88 percent of the white women reported having experienced gender discrimination. In the light of research associating negative stressors with poor health outcomes, including elevated blood pressure, future studies should assess public health implications of discrimination based on sexual orientation, in conjunction with racial and gender discrimination.

Purpose This study examined race by sex differences in depression symptoms and psychosocial service use (pastors, social workers, mental health workers, support groups) among patients with lung cancer. Patients and Methods The multiregional Cancer Care Outcomes Research and Surveillance study surveyed black and white adults with stages I to III lung cancer (n = 1,043) about depression symptoms, interest in help for mood, and psychosocial service use. Multivariable logistic regression was used to evaluate race/sex differences in depression symptoms (modified Center for Epidemiologic Studies Depression Scale ≥ 6) and psychosocial service use, independent of demographic, clinical, psychosocial, and behavioral covariates. Results A total of 18.2% screened positive for depression symptoms. This proportion was highest among black men (24.7%), followed by white women (20.6%), black women (15.8%), and white men (15.0%). In adjusted analyses, white women showed greater risk for depression symptoms relative to black women (P = .01) and white men (P = .002), with no other differences among groups. Black patients were less likely than white patients to receive desired help for mood from their doctors (P = .02), regardless of sex. Among all patients, black women were most likely to have contact with pastoral care and social work. Conclusion Race and sex interacted to predict risk of depression symptoms. Covariates accounted for elevated risk among black men. White women showed greater risk than black women and white men, independent of covariates. Black patients may experience greater barriers to receiving help for mood from their doctors. Race by sex differences in contact with psychosocial services highlight potential differences in the extent to which services are available, acceptable, and/or sought by patients.
