Differences in African American and white women with myocardial infarction: history, presentation, diagnostic methods, and infarction type

BACKGROUND: Despite overall declining death rates from cardiovascular disease, the number of women dying of cardiovascular disease increases each year, with substantially higher rates in African American women than in white women. OBJECTIVE: To investigate differences in presentation, diagnostic method, and type of infarction between African American and white women with myocardial infarction. METHODS: Chart review of all women with discharge diagnosis of myocardial infarction. RESULTS: No significant differences were found between African American and white women in admitting diagnosis, diagnostic methods, or type of infarction. At the time of admission, 2 medical history variables, stroke and hypertension, differed significantly between African American and white women (P = .027 and P = .002, respectively). CONCLUSIONS: Healthcare professionals must be aware of possible racial differences in medical history, signs and symptoms, and prognosis when assessing patients and planning interventions. Studies with larger samples are needed to confirm these findings on African American and white women with myocardial infarction.

Objectives: African American children are at higher risk of obesity than White children and African American women are more likely to undergo caesarean-section (CS) delivery than White women. CS is associated with childhood obesity, however, little is known whether this relationship varies by race.We examined if the association of CS with obesity at age 2 years varied by race. Design: Longitudinal birth cohort.Setting: Birth cohort conducted in a health care system in metropolitan Detroit, Michigan with follow-up at age 2 years.Participants: 639 birth cohort participants; 367 children (57.4%) were born to African American mothers and 230 (36.0%) children were born via CS.Main Outcome Measure: Obesity defined as body mass index ≥95th percentile at age 2 years.Results: Slightly more children of African American (n=37; 10.1%) than non-African American mothers (n=18; 6.6%) were obese (P=.12). There was evidence of effect modification between race and delivery mode with obesity at age 2 years (interaction P=.020). In children of African-American mothers, CS compared to vaginal birth was associated with a significantly higher odds of obesity (aOR=2.35 (95% CI: 1.16, 4.77), P=.017). In contrast, delivery mode was not associated with obesity at age 2 years in children of non-African-American mothers (aOR=.47 (95% CI: .13, 1.71), P=.25). Conclusions: There is evidence for a race-specific effect of CS on obesity at age 2 years; potential underlying mechanisms may be racial differences in the developing gut microbiome or in epigenetic programming. Future research is needed to determine if this racial difference persists into later childhood. Ethn Dis. 2016;26(1):61-68; doi:10.18865/ed.26.1.61

Purpose: To investigate disparities in treatment and outcomes between African-American and white women with endometrial cancer. Patients and Methods: We analyzed 1992 to 1998 Surveillance, Epidemiology, and End Results data for 21,561 women with epithelial cancers of the endometrium. Sequential Cox proportional hazard models were used to determine the association between tumor characteristics (stage, grade, and histologic type), sociodemographic characteristics (age and marital status), and treatment (surgery and radiation therapy) and the racial difference in mortality. Results: The unadjusted hazard ratio (HR) for death from endometrial cancer for African-American women compared with white women was 2.57. However, African-American women were significantly more likely to present with advanced-stage disease and have poorly differentiated tumors or tumors with an unfavorable histologic type and were significantly less likely to undergo definitive surgery at all stages of disease. Adjusting for tumor and sociodemographic characteristics lowered the HR for African-American women to 1.80. Further adjustment for the use of surgery reduced the HR to 1.51. The association between surgery and survival was stronger among white women (HR, 0.26) than among African-American women (HR, 0.44). Conclusion: African-American women with endometrial cancer are significantly less likely to undergo primary surgery and have significantly shorter survival than white women with endometrial cancer. Racial differences in treatment are associated with racial differences in survival. The association between use of surgery and survival is weaker among African-American than white women, raising questions about potential racial differences in the effectiveness of surgery.

Objective: We set out to determine if a primarily Internet-delivered behavioral weight loss intervention produced differential weight loss in African American and non-Hispanic White women, and to identify possible mediators.Design: Data for this analysis were from a randomized controlled trial, collected at baseline and 4-months.Setting: The intervention included monthly face-to-face group sessions and an Internet component that participants were recommended to use at least once weekly.Participants: We included overweight or obese African American and non-Hispanic White women (n=170), with at least weekly Internet access, who were able to attend group sessions.Intervention: Monthly face-to-face group sessions were delivered in large or small groups. The Internet component included automated tailored feedback, self-monitoring tools, written lessons, video resources, problem solving, exercise action planning tools, and social support through message boards.Main outcome measure: Multiple linear regression was used to evaluate race group differences in weight change.Results: Non-Hispanic White women lost more weight than African American women (-5.03% vs.-2.39%, P=.0002). Greater website log-ins and higher change in Eating Behavior Inventory score in non-Hispanic White women partially mediated the race-weight loss relationship.Conclusions: The weight loss disparity may be addressed through improved website engagement and adoption of weight control behaviors.

Treatment Decisions

Purpose High rates of mastectomy and marked regional variations have motivated lingering concerns about overtreatment and failure to involve women in treatment decisions. We examined the relationship between patient involvement in decision making and type of surgical treatment for women with breast cancer. Methods All women with ductal carcinoma-in-situ and a 20% random sample of women with invasive breast cancer aged 79 years and younger who were diagnosed in 2002 and reported to the Detroit and Los Angeles Surveillance, Epidemiology, and End Results registries were identified and surveyed shortly after receipt of surgical treatment (response rate, 77.4%; n = 1,844). Results Mean age was 60.1 years; 70.2% of the women were white, 18.0% were African American, and 11.8% were from other ethnic groups. Overall, 30.2% of women received mastectomy as initial treatment. Most women reported that they made the surgical decision (41.0%) or that the decision was shared (37.1%); 21.9% of patients reported that their surgeon made the decision with or without their input. Among white women, only 5.3% of patients whose surgeon made the decision received mastectomy compared with 16.8% of women who shared the decision and 27.0% of women who made the decision (P < .001, adjusted for clinical factors, predisposing factors, and number of surgeons visited). However, this association was not observed for African American women (Wald test 10.0, P = .041). Conclusion Most women reported that they made or shared the decision about surgical treatment. More patient involvement in decision making was associated with greater use of mastectomy. Racial differences in the association of involvement with receipt of treatment suggest that the decision-making process varies by racial groups.

Insulin resistance is associated with endothelial dysfunction. Because African-American women are more insulin-resistant than white women, it is assumed that African-American women have impaired endothelial function. However, racial differences in postprandial endothelial function have not been examined. In this study, we test the hypothesis that African-American women have impaired postprandial endothelial function compared with white women. Postprandial endothelial function following a breakfast (20% protein, 40% fat, and 40% carbohydrate) was evaluated in 36 (18 African-American women, 18 white women) age- and body mass index (BMI)-matched (age: 37 ± 11 yr; BMI: 30 ± 6 kg/m2) women. Endothelial function, defined by percent change in brachial artery flow-mediated dilation (FMD), was measured at 0, 2, 4, and 6 h following a meal. There were no significant differences between the groups in baseline FMD, total body fat, abdominal visceral fat, and fasting levels of glucose, insulin, total cholesterol, low-density lipoprotein cholesterol, or serum estradiol. Although African-American women were less insulin-sensitive [insulin sensitivity index (mean ± SD): 3.6 ± 1.5 vs. 5.2 ± 2.6, P = 0.02], both fasting triglyceride (TG: 56 ± 37 vs. 97 ± 49 mg/dl, P = 0.007) and incremental TG area under the curve (AUC0–6hr: 279 ± 190 vs. 492 ± 255 mg·dl−1·min−1·10−2, P = 0.008) were lower in African-American than white women. Breakfast was associated with a significant increase in FMD in whites and African-Americans, and there was no significant difference in postprandial FMD between the groups ( P > 0.1 for group × time interactions). Despite being insulin-resistant, postprandial endothelial function in African-American women was comparable to white women. These results imply that insulin sensitivity may not be an important determinant of racial differences in endothelial function.

Objective: Persistent and consistently observed racial disparities in physical functioning likely stem from racial differences in social resources and environmental conditions. Method: We examined the association between race and reported difficulty performing instrumental activities of daily living (IADL) in 347 African American (45.5%) and Whites aged 50 or above in the Exploring Health Disparities in Integrated Communities–Southwest Baltimore, Maryland Study (EHDIC-SWB). Results: Contrary to previous studies, African Americans had lower rates of disability (women: 25.6% vs. 44.6%, p = .006; men: 15.7% vs. 32.9%; p = .017) than Whites. After adjusting for sociodemographics, health behaviors, and comorbidities, African American women (odds ratio [OR] = 0.32, 95% confidence interval [CI] = [0.14, 0.70]) and African American men (OR = 0.34, 95% CI = [0.13, 0.90]) retained their functional advantage compared with White women and men, respectively. Conclusion: These findings within an integrated, low-income urban sample support efforts to ameliorate health disparities by focusing on the social context in which people live.

First Year

Objective Allostatic load (AL) represents multisystem physiological “wear-and-tear” reflecting emerging chronic disease risk. We assessed AL during the first year postpartum in a diverse community sample with known health disparities. Study Design The Eunice Kennedy Shriver National Institute for Child Health and Human Development Community Child Health Network enrolled 2,448 predominantly low-income African-American, Latina, and White women immediately after delivery of liveborn infants at ≥20 weeks' gestation, following them over time with interviews, clinical measures, and biomarkers. AL at 6 and 12 months postpartum was measured by body mass index, waist:hip ratio, blood pressure, pulse, hemoglobin A1c, high-sensitive C-reactive protein, total cholesterol and high-density lipoprotein, and diurnal cortisol slope. Results Adverse AL health-risk profiles were significantly more prevalent among African-American women compared with non-Hispanic Whites, with Latinas intermediate. Breastfeeding was protective, particularly for White women. Complications of pregnancy were associated with higher AL, and disparities persisted or worsened through the first year postpartum. Conclusion Adverse AL profiles occurred in a substantial proportion of postpartum women, and disparities did not improve from birth to 1 year. Breastfeeding was protective for the mother.
