Warm partner contact is related to lower cardiovascular reactivity

The authors investigated the relationship between brief warm social and physical contact among cohabitating couples and blood pressure (BP) reactivity to stress in a sample of healthy adults (66 African American, 117 Caucasian; 74 women, 109 men). Prior to stress, the warm contact group underwent a 10-minute period of handholding while viewing a romantic video. Followed by a 20-second hug with their partner, while the no contact group rested quietly for 10 minutes and 20 seconds. In response to a public speaking task, individuals receiving prestress partner contact demonstrated lower systolic BP diastolic BP, and heart rate increases compared with the no contact group. The effects of warm contact were comparable for men and women and were greater for African Americans compared with Caucasians. These findings suggest that affectionate relationships with a supportive partner may contribute to lower reactivity to stressful life events and may partially mediate the benefit of marital support on better cardiovascular health.     

Beliefs about racism and health among African American women with diabetes: a qualitative study

Exposure to racism has been linked to poor health outcomes. Little is known about the impact of racism on diabetes outcomes. This study explored African American women's beliefs about how racism interacts with their diabetes self-management and control. Four focus groups were conducted with a convenience sample of 28 adult African American women with type 2 diabetes who were recruited from a larger quantitative study on racism and diabetes. The focus group discussions were transcribed verbatim and analyzed by the authors. Women reported that exposure to racism was a common phenomenon, and their beliefs did in fact link racism to poor health. Specifically, women reported that exposure to racism caused physiological arousal including cardiovascular and metabolic perturbations. There was consensus that physiological arousal was generally detrimental to health. Women also described limited, and in some cases maladaptive, strategies to cope with racist events, including eating unhealthy food choices and portions. There was consensus that the subjective nature of perceiving racism and accompanying social prohibitions often made it impossible to address racism directly. Many women described anger in such situations and the tendency to internalize anger and other negative emotions, only to find that the negative emotions would be reactivated repeatedly with exposure to novel racial stressors, even long after the original racist event remitted. African American women in this study believed that racism affects their diabetes self-management and control. Health beliefs can exert powerful effects on health behaviors and may provide an opportunity for health promotion interventions in diabetes.     

Warm Partner Contact Is Related to Lower Cardiovascular Reactivity

Abstract

The authors investigated the relationship between brief warm social and physical contact among cohabitating couples and blood pressure (BP) reactivity to stress in a sample of healthy adults (66 African American, 117 Caucasian; 74 women, 109 men). Prior to stress, the warm contact group underwent a 10-minute period of handholding while viewing a romantic video, followed by a 20-second hug with their partner, while the no contact group rested quietly for 10 minutes and 20 seconds. In response to a public speaking task, individuals receiving prestress partner contact demonstrated lower systolic BP, diastolic BP, and heart rate increases compared with the no contact group. The effects of warm contact were comparable for men and women and were greater for African Americans compared with Caucasians. These findings suggest that affectionate relationships with a supportive partner may contribute to lower reactivity to stressful life events and may partially mediate the benefit of marital support on better cardiovascular health.     

Experiences of racist events are associated with negative health consequences for African American women

This study investigated whether experiences of racist events were related to psychological distress, negative health behaviors, and health problems. Participants were 71 African American women (mean age 44.4) who were recruited from an urban cancer-screening clinic as part of a larger longitudinal study on familial risk of breast cancer. Participants completed three study assessments, approximately one month apart, and data were collected via self-report. Correlational analyses revealed that past year and lifetime racism were both related to psychological distress. Among smokers and drinkers, past year racism was positively correlated with number of cigarettes and drinks consumed. Lifetime racism was negatively related to perceived health, and positively related to lifetime history of physical disease and frequency of recent common colds. Analyses using a general linear model revealed that these relationships were largely unaccounted for by other variables. In addition, demographic variables such as income and education were not related to experiences of racism. The results suggest that racism can be detrimental to African American's well being and should be investigated in health disparities research.     

Racial identity and autonomic responses to racial discrimination

Several studies identify racial identity—the significance and meaning that individuals attribute to race—as a mitigating factor in the association between racial discrimination and adjustment. In this study, we employed a visual imagery paradigm to examine whether racial identity would moderate autonomic responses to blatant and subtle racial discrimination analogues with Black and White perpetrators. We recruited 105 African American young adults from a public, southeastern university in the United States. The personal significance of race as well as personal feelings about African Americans and feelings about how others view African Americans moderated autonomic responses to the vignettes. We use polyvagal theory and a stress, appraisal, and coping framework to interpret our results with an eye toward elucidating the ways in which racial identity may inform individual differences in physiological responses to racial discrimination.     

Stress, stress reduction, and hypertension in African Americans: an updated review.

This is a comprehensive and integrative review of multiple factors underlying the greater prevalence of hypertension in African Americans compared with whites. Evidence linking stress with hypertension and cardiovascular disease in African Americans is reviewed. A survey of mechanisms of hypertension in African Americans and existing behavioral strategies for the treatment of hypertension is presented. Given that the excess of hypertension may be mediated in part by behavioral factors operating through biological mechanisms, a case is presented for behavioral stress reduction measures. This review of stress reduction techniques especially the Transcendental Mediation program for the treatment of hypertension in African Americans highlights current issues facing the field. New information is provided to help direct future nonpharmacological research and practice in hypertension to prevent morbidity and premature mortality in this underserved population.     

Colorism Demonstrates Dampened Effects Among Young Black Men Who Have Sex with Men in Chicago

Background/purposeColorism is a well documented phenomenon affecting the health, income, education, and psychological wellbeing of African Americans with differing skin tones. There is little research, however, around how colorism may operate among intersectional racial sexual minorities, who additionally face both racism and homophobia, despite evidence that different forms of oppression interact with each other and may have modulating effects in this population. This study aims to clarify the effect colorism has on a variety of life and health outcomes in young black men who have sex with men (YBMSM).MethodsData were obtained from interviews conducted as part of the uConnect study, a longitudinal cohort study of YBMSM on the South Side of Chicago. Skin color of participants was rated by independent raters.ResultsWhile some previously found patterns in African American heterosexuals were observed in this population, most were not.ConclusionThe effects of colorism did not appear to have a significant role among this population across a wide set of social and health domains.     

Exploring beliefs about prostate cancer and early detection in men and women of three ethnic groups

OBJECTIVES: Practice guidelines support informed or shared decision-making about prostate cancer screening. To compare beliefs across three racial/ethnic categories concerning prostate cancer etiology and risk, screening routines, and shared decision-making, we conducted 12 focus groups. METHODS: Participants were recruited in primary care settings and included 33 African Americans, 35 Hispanics, and 22 non-Hispanic Whites. Of the 90 participants, 53% were male. RESULTS: Groups identified heredity, age, race, sexual activity, and other lifestyle influences as risk factors. Few were aware that prostate cancer is asymptomatic in early stages. Confidence in knowledge of screening routines was high, but included misconceptions supporting initiation of screening at earlier ages and at shorter intervals than professional recommendations. Females encouraged screening of male relatives to protect their health. DISCUSSION AND CONCLUSION: While racial/ethnic groups had similar views and knowledge about screening, African Americans wanted to organize to address the threat of prostate cancer in their communities. Hispanics had awakening awareness of the health risks of prostate cancer. Non-Hispanic Whites were aware of the health threat of prostate cancer, but their approach to health protection was more individual and less community focused than that of African Americans. Participants were not aware of controversy about screening. PRACTICE IMPLICATIONS: Developers of educational materials to support informed or shared decision-making should be aware that initial views of prostate cancer screening are positive.     

Prolonged marital stress is associated with short‐lived responses to positive stimuli

Marital stress is associated with a higher incidence of psychiatric disorders, in particular major depression. One pathway through which marital stress may impact emotional health is by compromising emotion‐responding processes. We examined a longitudinal sample of adults (N = 116; 59 males; 39–84 years) to verify how marital stress predicts reactivity to, and recovery from, emotional provocation. Individuals watched positive, neutral, and negative pictures while an objective measure of affective state, corrugator supercilii muscle activity, was recorded continuously. Our results indicate that marital stress is associated with short‐lived responses to positive pictures, indexed by a less persistent decrease in corrugator activity after picture offset. Extending beyond the prior focus on negative emotional processes, these results suggest that social stress may impact health by influencing the time course of responding to positive events.     

Associations between patient–provider communication and socio-cultural factors in prostate cancer patients: A cross-sectional evaluation of racial differences

Objective

To examine the association between socio-cultural factors and patient–provider communication and related racial differences.

Methods

Data analysis included 1854 men with prostate cancer from a population-based study. Participants completed an assessment of communication variables, physician trust, perceived racism, religious beliefs, traditional health beliefs, and health literacy. A multi-group structural equation modeling approach was used to address the research aims.

Results

Compared with African Americans, Caucasian Americans had significantly greater mean scores of interpersonal treatment (p < 0.01), prostate cancer communication (p < 0.001), and physician trust (p < 0.001), but lower mean scores of religious beliefs, traditional health beliefs, and perceived racism (all p values <0.001). For both African and Caucasian Americans, better patient–provider communication was associated with more physician trust, less perceived racism, greater religious beliefs (all p-values <0.01), and at least high school education (p < 0.05).

Conclusion

Socio-cultural factors are associated with patient–provider communication among men with cancer. No evidence supported associations differed by race.

Practice implication

To facilitate patient–provider communication during prostate cancer care, providers need to be aware of patient education levels, engage in behaviors that enhance trust, treat patients equally, respect religious beliefs, and reduce the difficulty level of the information.     

Perceived racial discrimination as an independent predictor of sleep disturbance and daytime fatigue

Perceived discrimination is a potential cause of racial and ethnic disparities in health. Disturbed sleep may serve as a mechanism linking perceived racism with health consequences. This study investigates data from 7,148 adults from Michigan and Wisconsin who participated in the 2006 Behavioral Risk Factor Surveillance System. Hierarchical logistic regression analyses explored associations between perceived racial discrimination and self-reported sleep disturbance and daytime fatigue. Sleep disturbance and daytime fatigue were reported in 19% and 21% of the sample, respectively. Black/African American respondents (21%) report perceiving worse experiences, compared to people of other races, when seeking health care at higher rates than non-Hispanic White respondents (3%). Results from logistic regression models show that perceived racial discrimination is associated with increased risks of sleep disturbance (odds ratio [OR] = 2.62, p < .0001) and daytime fatigue (OR = 2.07, p < .0001). After adjustment for all covariates, perceived discrimination remains a significant predictor of sleep disturbance (OR = 1.60, p = .04). The interaction between perceived racism and race (Black/African American vs. non-Hispanic White) was nonsignificant. This population-based research adds to the growing body of data, suggesting that perceived racism may impact health via its influence on sleep-wake behaviors.     

Epigenetics and the embodiment of race: Developmental origins of US racial disparities in cardiovascular health

The relative contribution of genetic and environmental influences to the US black‐white disparity in cardiovascular disease (CVD) is hotly debated within the public health, anthropology, and medical communities. In this article, we review evidence for developmental and epigenetic pathways linking early life environments with CVD, and critically evaluate their possible role in the origins of these racial health disparities. African Americans not only suffer from a disproportionate burden of CVD relative to whites, but also have higher rates of the perinatal health disparities now known to be the antecedents of these conditions. There is extensive evidence for a social origin to prematurity and low birth weight in African Americans, reflecting pathways such as the effects of discrimination on maternal stress physiology. In light of the inverse relationship between birth weight and adult CVD, there is now a strong rationale to consider developmental and epigenetic mechanisms as links between early life environmental factors like maternal stress during pregnancy and adult race‐based health disparities in diseases like hypertension, diabetes, stroke, and coronary heart disease. The model outlined here builds upon social constructivist perspectives to highlight an important set of mechanisms by which social influences can become embodied, having durable and even transgenerational influences on the most pressing US health disparities. We conclude that environmentally responsive phenotypic plasticity, in combination with the better‐studied acute and chronic effects of social‐environmental exposures, provides a more parsimonious explanation than genetics for the persistence of CVD disparities between members of socially imposed racial categories.

Ethnic differences in self-reported sleep problems in older adults.

STUDY OBJECTIVES: To date, conflicting observations have been made regarding ethnic differences in sleep patterns. Plausibly, differing sampling strategies and disparity in the cohorts investigated might help explain discrepant findings. To our knowledge population-based studies investigating ethnic differences in sleep complaints have not addressed within-group ethnic heterogeneity, although within-group health disparities have been documented. DESIGN: Volunteers (n =1118) in this study were community-residing older European Americans and African Americans residing in Brooklyn, New York, which were recruited by a stratified, cluster sampling technique. Trained interviewers of the same race as the respondents gathered data during face-to-face interviews conducted either in the respondent's home or another location of their choice. Data included demographic and health risk factors, physical health, social support, and emotional experience. Relationships of demographic and health risk factors to sleep disturbances were examined in multiple linear regression analyses. Within-group differences in sleep complaints were also explored. SETTING: N/A. PARTICIPANTS: N/A. INTERVENTIONS: N/A. MEASUREMENTS AND RESULTS: Of the factors showing significant associations with sleep disturbance, European American ethnicity was the most significant predictor (r2 = 0.20). Worse sleep and greater reliance on sleep medicine were observed among European Americans. Caribbean Americans reported less sleep complaints than did U.S.-born African Americans, and immigrant European Americans reported greater complaints than did US-born European Americans. CONCLUSIONS: As expected several health risk factors were predictive of sleep disturbance among urban community-dwelling older adults, but ethnicity was the most significant predictor. The present data suggest both between-group and within-group ethnic differences in sleep complaints. Understanding of demographic and cultural differences between African Americans and European Americans may be critical in interpreting subjective health-related data.     

Colon cancer screening consultations may identify racial disparity in hypertension diagnosis and management

There are significant health disparities between African Americans and whites in the United States. While colon cancer screening aids in decreasing the morbidity and mortality from colon cancer in African Americans, other health risks may also be identified during gastroenterology consultations. This study evaluated whether there is a disparity in the prevalence of hypertension and hypertension management in African Americans compared to whites who are referred for colon cancer screening consultations. The medical records of 258 patients (90 African Americans and 168 whites) were reviewed. Seventy-two of 90 (80%) African-American patients and 42 of 168 (25%) white patients had hypertension. There was a statistically significant difference (p < 0.005) in the rate of hypertension in African Americans compared to whites. Medications were prescribed by their referring physicians for 42 (58%) of the hypertensive African Americans, with 36 noted to have inadequately controlled blood pressure. Thirty (42%) of the hypertensive African-American patients were never prescribed blood pressure medications. Medications were prescribed by their referring physician for 36 (86%) of the hypertensive white patients, with six noted to have inadequately controlled blood pressure. Six (14%) of the hypertensive white patients were never prescribed blood pressure medications. There was a statistically significant difference in the rate of blood pressure control (p = 0.007) between African-American and white patients who were referred for colon cancer screening. Increased efforts are necessary to identify critical health concerns of all patients and to decrease health disparities between African Americans and whites in the United States.     

Targeting and tailoring message-framing: the moderating effect of racial identity on receptivity to colorectal cancer screening among African–Americans

This study demonstrates the potential of racial identity to moderate how gain and loss-framed messaging, as well as culturally-targeted messaging, can affect receptivity to preventive health screening. African–Americans (N?=?132) who were noncompliant with recommended colorectal cancer (CRC) screening completed a measure of racial identity centrality—encompassing the extent to which racial identity is a core component of self-concept—and then participated in an online education module about CRC screening, during which either gain or loss-framed messaging was introduced. Half of African–Americans were also exposed to a culturally-targeted self-help message about preventing CRC. Theory of Planned Behavior measures of attitudes, normative beliefs, perceived behavioral control, and intentions to obtain a CRC screen served as outcomes. Results confirmed that effects of messaging on receptivity to CRC screening depended on racial identity. Among low racial identity African Americans, gain-framed messaging most effectively increased normative beliefs about obtaining CRC screening, whereas among high racial identity African Americans loss-framed messaging was most compelling. However, these effects most strongly emerged when culturally-targeted self-help messaging was included. We discuss implications for health disparities theory and research, including a potential to simultaneously deploy culturally-targeted and tailored messaging based on racial identity.     

Racial differences in informal help seeking for mental health problems

The present study examined the hypothesis of greater African American informal help seeking for mental health problems in a comparison of African Americans and Whites. Controlling for sociodemographic factors, symptom distress, and diagnosis, African Americans were less likely than Whites to report turning for assistance to a friend, family member, or religious figure. Nor did African Americans use informal help as a substitute for professional care; they turned to informal helpers in conjunction with formal helpers, and demonstrated complementarity to a greater extent than Whites. Supportive ties found among African Americans may be advantageous for many purposes, but provide no benefit for the face-to-face discussion of emotional problems. © 1998 John Wiley & Sons, Inc.     

Effects of perceived racism, cultural mistrust and trust in providers on satisfaction with care

Discriminatory treatment of African Americans in healthcare is well recognized, yet the literature is unclear on the specific role that perceived racism and mistrust play in the patient-provider relationship. The purpose of this study was to test a mid-range theoretical model entitled Perceptions of Racism and Mistrust in Health Care (PRMHC). This model hypothesized that perceived racism influences cultural mistrust, which affects trust in providers--and these combined psychosocial aspects of healthcare affect satisfaction with the care received. One-hundred-forty-five African-American subjects participated in structured interviews to collect demographic and psychosocial data. Provider data was obtained through chart audits. In a group of low-income African Americans in two primary care clinics, perceptions of racism and mistrust of whites had a significant negative effect on trust and satisfaction. Perceived racism had both a significant, inverse direct effect on satisfaction as well as a significant indirect effect on satisfaction mediated by cultural mistrust and trust in provider. Structural equation modeling analysis supported the hypothesized theoretical relationships and explained 27% of the variance in satisfaction with care. The findings add to the existing literature by enhancing our understanding of the complex perspectives on trust and overall satisfaction with care among African-American patients. Results suggest that improving health outcomes for African Americans requires a broader understanding of cultural competence, one that addresses societal racism and its impact on provider-patient relationships.     

Comorbidities and Challenges Affecting African Americans with HIV Infection

The significant disparities in health outcomes that exist among racial minorities in the United States are clearly evident in the HIV epidemic. HIV disproportionately affects minorities, African Americans in particular. Current treatment of HIV/AIDS is complicated by medical problems such as hepatitis, diabetes and dyslipidemia, which also disproportionately affect African Americans and can significantly impact the complexity of clinical care. In addition, untreated psychological problems such as depression and societal barriers to adequate medical care may decrease treatment adherence and increase HIV-related morbidity and mortality among African Americans. Consideration of these issues by healthcare providers is necessary to optimize care and improve treatment outcomes for African Americans with HIV infection.
