Project description:ObjectiveNumerous studies have found evidence of a link between perceived discrimination and unhealthy behavior, especially substance use. Within this body of literature, however, several studies have found unexpected evidence of a positive relation between perceived racial discrimination among African Americans-mostly women-and certain types of healthy behavior, primarily exercise and healthy eating. The current study further examined this positive relation, including an anticipated moderator: optimism. It also examined the relation between perceived racial discrimination and a correlate of unhealthy behavior: BMI.MethodSix waves of data were collected over 14 years in three related samples of African Americans from families participating in the Family and Community Health Study. Each family included an adolescent (Mage = 10.5 at Wave 1), the adolescent's primary caregiver (Mage = 37), and, in some cases, an older sibling of that adolescent (Mage = 13). Wave 1 Ns were 889, 889, and 295, respectively. Healthy behavior was defined as diet and exercise.ResultsThere was very little evidence of a long-term relation between perceived racial discrimination and BMI in any sample, and no evidence of a relation between discrimination and healthy behavior among the males. However, correlational analyses revealed a positive prospective relation between discrimination and healthy behavior among all three groups of females; structural equation modeling indicated that this relation was stronger among women who were high in optimism.ConclusionsPerceived racial discrimination does not appear to be related to BMI among African Americans, but it is related to healthy behavior among Black females who are high in dispositional optimism.

Project description:ObjectiveExplore interactive relations of lifetime discrimination burden and racial discrimination-chronic stressors among African Americans (AAs)-and age with MRI-assessed white matter lesion volume (WMLV), a prognostic indicator of poor clinical brain health outcomes.MethodAAs (N = 71; 60.6% female, mean age = 50) participating in the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) SCAN study underwent quantitative magnetic resonance imaging coded for WMLV. Participants self-reported lifetime discrimination burden and racial discrimination approximately 5 years earlier. Multivariable regression models assessed interactions of linear and quadratic effects of discrimination and age with WMLV adjusted for sex and socioeconomic status.ResultsFindings revealed significant interactive relations of age and (a) quadratic, lifetime discrimination burden, B = .05, p = .014, ηpartial2 = .092, and (b) quadratic, racial discrimination, B = .03, p = .001, ηpartial2 = .155, with WMLV. Among older AA, increases in lifetime discrimination burden and racial discrimination were associated with increases in WMLV (ps < .03); in younger AA, decreasing levels of racial discrimination were related to increases in WMLV (p = .006).ConclusionsAmong older AA, as lifetime discrimination burden and racial discrimination increased, so did WMLV. However, in younger AA, decreases in racial discrimination were associated with increased WMLV. Elucidation of complex mechanistic underpinnings, including potentially differential impacts of the acknowledgment versus suppression or underreporting of discriminatory experiences, among AA of different age cohorts, is critical to understanding the present pattern of findings.

Project description:OBJECTIVE:This study examined the role of depressive symptoms in mediating the relationship between early life experiences of racial discrimination and accelerated aging in adulthood for African Americans (i.e., prediction over a 19-year period, from ages 10 to 29) after adjusting for gender and health behaviors. METHOD:Longitudinal self-report data over 7 waves of data collection from the Family and Community Health Study were utilized. The sample included 368 African Americans with usable gene expression data to compute accelerated aging, as well as complete data on all self-report variables including racial discrimination (Schedule of Racist Events) and depression (Diagnostic Interview Schedule for Children-Version 4). Blood was collected by antecubital blood draws from participants at age 29. The proposed model was tested by path analysis. RESULTS:Findings revealed that high discrimination at ages 10-15 was associated with depression at ages 20-29 (? = .19, p = .001), controlling for depression at ages 10-15, which, in turn, was related to accelerated cellular-level aging (? = .11, p = .048) after controlling for gender, alcohol consumption, and cigarette use. The indirect effect of racial discrimination on aging through depression at ages 20-29 was significant (? = .021, 95% confidence interval [.001, .057]), accounting for 32.3% of the total variance. CONCLUSION:These findings support research conceptualizations that early life stress due to racial discrimination lead to sustained negative affective states continuing into young adulthood that confer risk for accelerated aging and possibly premature disease and mortality in African Americans. These findings advance knowledge of potential underlying mechanisms that influence racial health disparities. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Project description:OBJECTIVE:Telomeres are protective sequences of DNA capping the ends of chromosomes that shorten over time. Leukocyte telomere length (LTL) is posited to reflect the replicative history of cells and general systemic aging of the organism. Chronic stress exposure leads to accelerated LTL shortening, which has been linked to increased susceptibility to and faster progression of aging-related diseases. This study examined longitudinal associations between LTL and experiences of racial discrimination, a qualitatively unique source of minority psychosocial stress, among African Americans. METHOD:Data are from 391 African Americans in the Coronary Artery Risk Development in Young Adults (CARDIA) Telomere Ancillary Study. We examined the number of domains in which racial discrimination was experienced in relation to LTL collected in Years 15 and 25 (Y15: 2000/2001; Y25: 2010/2011). Multivariable linear regression examined if racial discrimination was associated with LTL. Latent change score analysis (LCS) examined changes in racial discrimination and LTL in relation to one another. RESULTS:Controlling for racial discrimination at Y15, multivariable linear regression analyses indicated that racial discrimination at Y25 was significantly associated with LTL at Y25. This relationship remained robust after adjusting for LTL at Y15 (b = -.019, p = .015). Consistent with this finding, LCS revealed that increases in experiences of racial discrimination were associated with faster 10-year LTL shortening (b = -.019, p = .015). CONCLUSIONS:This study adds to evidence that racial discrimination contributes to accelerated physiologic weathering and health declines among African Americans through its impact on biological systems, including via its effects on telomere attrition.

Project description:The adverse impact of racial discrimination on youth, and particularly its impact on the development of depressive symptoms, has prompted attention regarding the potential for family processes to protect youth from these erosive effects. Evidence from non-experimental studies indicates that protective parenting behavior (PPB) which occurs naturally in many Black families can buffer youth from the negative impact of racial discrimination. Of interest is whether "constructed resilience" developed through family-centered prevention programming can add to this protective buffering. The current paper examines the impact of constructed resilience in the form of increased protective parenting using 295 families randomly assigned either to a control condition or to the Protecting Strong African American Families (ProSAAF) program, a family-based prevention program previously shown to enhance protective parenting. We found that baseline racial discrimination was predictive of change in youths' depressive symptoms across the pre-post study period. Second, we found that parents participating in ProSAAF, relative to those randomly assigned to the control group, significantly improved in their use of an intervention targeting PPB. Third, we found a significant effect of change in PPB on the association of discrimination with change in depressive symptoms. Finally, we found that ProSAAF participation buffered the impact of racial discrimination on change in depressive symptoms through change in PPB. Results provide experimental support for constructed resilience in the form of change in PPB and call for increased attention to the development of family-based intervention programs to protect Black youth from the pernicious effects of racial discrimination.

Project description:BackgroundRacial discrimination is one of many barriers experienced by African Americans that interfere with health self-care management. Discrimination stress may decrease the tendency for individuals to resonate with the social-emotional appeals embedded in persuasive health information, which are known to play a key role in producing behavior change. Understanding the neurobehavioral underpinnings of discrimination stress experienced by African Americans may help reduce or resolve this important health disparity.ObjectivesThe purpose of this secondary analysis was to examine the association between neural processing of health information and perceived discrimination. In particular, we focused on three previously identified measures of health information processing associated with distinct brain areas: analytic network, empathy network, and the ventral medial prefrontal cortex.MethodsData were obtained from 24 African Americans enrolled in a blood pressure self-care management study. Participants completed surveys assessing racial discrimination and global stress, as well as a 40-minute functional magnetic resonance imaging protocol used to measure neural activation associated with processing different types of health information.ResultsDiscrimination stress was significantly related to reduced activation of the empathy network and ventral medial prefrontal cortex, whereas there was a nonsignificant positive relationship with activity in the analytic network.DiscussionUncovering associations between patient experiences, such as racial discrimination, and their neural processing of health information can lead to the development of tailored health messages and self-care management interventions. This may inform strategies to close the gap on health outcomes.

Project description:Racial discrimination is a common stressor for African Americans, with negative consequences for mental and physical well-being. It is likely that these effects extend into the family, but little research has examined the association between racial discrimination and couple functioning. This study used dyadic data from 344 rural, predominantly low-income heterosexual African American couples with an early adolescent child to examine associations between self-reported racial discrimination, psychological and physical aggression, and relationship satisfaction and instability. Experiences of discrimination were common among men and women and were negatively associated with relationship functioning. Specifically, men reported higher levels of psychological aggression and relationship instability if they experienced higher levels of racial discrimination, and women reported higher levels of physical aggression if they experienced higher levels of racial discrimination. All results replicated when controlling for financial hardship, indicating unique effects for discrimination. Findings suggest that racial discrimination may be negatively associated with relationship functioning among African Americans and call for further research on the processes underlying these associations and their long-term consequences.

Project description:Leukocyte telomere length (LTL) is an indicator of general systemic aging, with shorter LTL being associated with several chronic diseases of aging and earlier mortality. Identifying factors related to LTL among African Americans may yield insights into mechanisms underlying racial disparities in health.To test whether the combination of more frequent reports of racial discrimination and holding a greater implicit anti-black racial bias is associated with shorter LTL among African-American men.Cross-sectional study of a community sample of 92 African-American men aged between 30 and 50 years. Participants were recruited from February to May 2010. Ordinary least squares regressions were used to examine LTL in kilobase pairs in relation to racial discrimination and implicit racial bias. Data analysis was completed in July 2013.After controlling for chronologic age and socioeconomic and health-related characteristics, the interaction between racial discrimination and implicit racial bias was significantly associated with LTL (b=-0.10, SE=0.04, p=0.02). Those demonstrating a stronger implicit anti-black bias and reporting higher levels of racial discrimination had the shortest LTL. Household income-to-poverty threshold ratio was also associated with LTL (b=0.05, SE=0.02, p<0.01).Results suggest that multiple levels of racism, including interpersonal experiences of racial discrimination and the internalization of negative racial bias, operate jointly to accelerate biological aging among African-American men. Societal efforts to address racial discrimination in concert with efforts to promote positive in-group racial attitudes may protect against premature biological aging in this population.

Project description:Background and aimsFrequent experiences of discrimination could increase vulnerability to tobacco withdrawal and smoking lapse in populations subject to tobacco-related health disparities. This laboratory study (2013-17) examined whether individual differences in perceived exposure to discrimination in one's daily life predicted tobacco withdrawal symptoms and smoking lapse behavior following acute tobacco deprivation in African American smokers.DesignMixed design with the between-subjects continuous variable of perceived discrimination crossed with the within-subject variable of tobacco deprivation status (deprived versus non-deprived).SettingAcademic medical center in Los Angeles, CA, USA.ParticipantsAfrican American non-treatment seeking daily cigarette smokers (n = 607, ≥ 10 cig/day).MeasurementsAt a baseline visit, self-reported frequency of perceived exposure to discrimination in one's daily life was measured [everyday discrimination scale (EDDS)]. At two subsequent counterbalanced experimental visits (16-hour tobacco deprivation versus ad-libitum smoking), self-report assessments of various tobacco withdrawal symptom domains [Brief Questionnaire of Smoking Urges), Wisconsin Smoking Withdrawal Scale (WSWS), Profile of Mood States (POMS), Snaith-Hamilton Pleasure Scale (SHAPS) and Current Impulsivity Scale (CIS)) and a behavioral smoking lapse analogue task were measured.FindingsAdjusted models demonstrated that greater frequency of perceived exposure to discrimination was associated with larger deprivation-induced increases in acute urges to smoke to alleviate negative mood, several negative mood states and subjective cognitive functioning-effect sizes were small in magnitude (βs = 0.09-0.13; Ps < 0.02). Data were inconclusive for associations between perceived exposure to discrimination and deprivation-induced changes in cravings, urges to smoke for pleasure, positive mood reduction, other symptoms or smoking reinstatement behavior.ConclusionsFrequency of perceived exposure to discrimination appears to be modestly associated with increased severity of some deprivation-induced tobacco withdrawal symptoms in African American smokers.

Project description:The relative contributions of racial and geographic factors to higher risk of stroke in people of African ancestry have not been unraveled. We compared stroke type and contributions of vascular risk factors among indigenous Africans (IA), African Americans (AA), and European Americans (EA).SIREN (Stroke Investigative Research and Educational Network) is a large multinational case-control study in West Africa-the ancestral home of 71% AA-whereas REGARDS (Reasons for Geographic and Racial Differences in Stroke) is a cohort study including AA and EA in the United States. Using harmonized assessments and standard definitions, we compared data on stroke type and established risk factors for stroke in acute stroke cases aged ?55 years in both studies.There were 811 IA, 452 AA, and 665 EA stroke subjects, with mean age of 68.0±9.3, 73.0±8.3, and 76.0±8.3 years, respectively (P<0.0001). Hemorrhagic stroke was more frequent among IA (27%) compared with AA (8%) and EA (5.4%; P<0.001). Lacunar strokes were more prevalent in IA (47.1%), followed by AA (35.1%) and then EA (21.0%; P<0.0001). The frequency of hypertension in decreasing order was IA (92.8%), followed by AA (82.5%) and then EA (64.2%; P<0.0001) and similarly for diabetes mellitus IA (38.3%), AA (36.8%), and EA (21.0%; P<0.0001). Premorbid sedentary lifestyle was similar in AA (37.7%) and EA (34.0%) but lower frequency in IA (8.0%).Environmental risk factors such as sedentary lifestyle may contribute to the higher proportion of ischemic stroke in AA compared with IA, whereas racial factors may contribute to the higher proportion of hypertension and diabetes mellitus among stroke subjects of African ancestry.
