Parental history of hypertension and coping responses predict blood pressure changes in black college volunteers undergoing a speaking task about perceptions of racism

Interethnic Group and Intraethnic Group Racism: Perceptions and Coping in Black University Students

This study explored perceived racism and the usual ways of coping with these perceptions in a sample of 269 Black university students (53% female). Perceptions of inter- and intragroup racism were assessed with the Life Experiences and Stress scale, and coping was measured with the Coping Orientations to Problems Experienced scale. A principal component analysis suggested that inter- and intragroup racism were separable constructs. Correlation analyses revealed that inter- and intragroup racism were negatively associated with self-deception.Relative to females, t-test analyses indicated that males perceived more inter- and intragroup racism. The t-test analyses also revealed that females were more likely than males to use emotion-focused and religious coping responses, when negotiating perceptions of inter- and intragroup racism; and, when negotiating perceptions of intragroup racism, males were more likely than females to use alcohol as a coping response. The limitations of the study and directions for future research are discussed.

Interactive effects of perceived racism and coping responses predict a school-based assessment of blood pressure in black youth

BACKGROUND

Research indicates that perceived racism and coping responses are associated with basal blood pressure (BP) levels and BP reactivity in Black adults. No study could be found, however, that has explored the independent and interactive effects of perceived racism and coping responses in a cohort who probably has the greatest risk of developing primary hypertension--Black youth.

PURPOSE

This study examined the relationship of perceived racism and coping responses to a continuous measure of BP and to a categorical measure of BP status (normal vs. high-normal or high).

METHODS

The convenience sample consisted of 217 Black youth (M age = 11.4 years, SD = 1.3). Participants reported on perceived racism and coping responses (Accepting It, Self-Blame, Taking Action, and Talking to Someone). BP was assessed with an automated monitor in school.

RESULTS

Approximately 32% of the sample had average BP levels that were high-normal or high. Hierarchical linear and logistic regression analyses were used to assess the predictive utility of perceived racism and the four coping responses to the continuous and categorical BP assessments. Although perceived racism and the coping response variables did not emerge as significant independent predictors in the linear or logistic regression analyses, perceived racism interacted with Accepting It (p = .009) in the linear regression analysis predicting systolic BP. Follow-up linear regression analyses indicated that perceived racism was not significantly associated with systolic BP among participants low in Accepting It but was inversely related to systolic BP among participants high in Accepting It. Perceived racism also interacted with Accepting It (p = .016) and Talking to Someone (p = .0009) in the logistic regression analysis predicting BP status. Follow-up logistic regression analyses revealed that (a) perceived racism was not significantly associated with BP status among participants low in Accepting It but was inversely related to BP status among participants high in Accepting It, and (b) perceived racism was inversely associated with BP status among participants low in Talking to Someone but was not significantly related to BP status among participants high in Talking to Someone.

CONCLUSIONS

The contribution of environmental and psychosocial factors to hypertension risk should be considered when exploring correlates of continuous and categorical assessments of BP in Black youth.

Perceived racism and cardiovascular reactivity and recovery to personally relevant stress

This study evaluated cardiovascular responses (CVR) to an active speech task with blatantly discriminatory (BRC) versus neutral (NRC) stimuli and an anger recall task in a sample of Black men (N = 73; age 18 to 47). Diastolic blood pressure scores were higher for NRC versus BRC stimuli during anger recall (p = .05). Moreover, persons in the NRC group who perceived high levels of racism (vs. no racism or BRC group) during active speech showed larger increases in blood pressure across postspeech rest, anger recall, and subsequent rest (p = .03). The notable elevation in CVR in response to an ambiguous event extends current models of racism suggesting that subtle racism is a psychosocial stressor that erodes health through chronically elevated CVR.

Perceived racism and vascular reactivity in black college women: moderating effects of seeking social support

This quasi-experimental study explored the association of perceived racism and seeking social support to vascular reactivity in a college sample of 110 Black women. Perceived racism and seeking social support were assessed via self-report, and vascular reactivity was measured before and during a standardized speaking task. Hierarchical regression analyses indicated that perceived racism was positively related to changes in systolic blood pressure. These analyses also indicated that seeking social support moderated the relationship between perceived racism and systolic blood pressure changes. This interaction effect persisted after controlling for several potential confounders. Follow-up regression analyses showed that perceived racism was positively associated with reactivity among participants who were low in seeking social support. A significant relationship was not observed between perceived racism and systolic blood pressure changes among participants who were high in seeking social support. Perceived racism and seeking social support were not significantly associated with changes in diastolic blood pressure. These findings highlight the importance of examining psychosocial factors that may mitigate the hypothesized relationship between perceived racism and reactivity.

A systematic review of empirical research on self-reported racism and health

This paper reviews 138 empirical quantitative population-based studies of self-reported racism and health. These studies show an association between self-reported racism and ill health for oppressed racial groups after adjustment for a range of confounders. The strongest and most consistent findings are for negative mental health outcomes and health-related behaviours, with weaker associations existing for positive mental health outcomes, self-assessed health status, and physical health outcomes. Most studies in this emerging field have been published in the past 5 years and have been limited by a dearth of cohort studies, a lack of psychometrically validated exposure instruments, poor conceptualization and definition of racism, conflation of racism with stress, and debate about the aetiologically relevant period for self-reported racism. Future research should examine the psychometric validity of racism instruments and include these instruments, along with objectively measured health outcomes, in existing large-scale survey vehicles as well as longitudinal studies and studies involving children. There is also a need to gain a better understanding of the perception, attribution, and reporting of racism, to investigate the pathways via which self-reported racism affects health, the interplay between mental and physical health outcomes, and exposure to intra-racial, internalized, and systemic racism. Ensuring the quality of studies in this field will allow future research to reveal the complex role that racism plays as a determinant of population health.

African American women's coping with health care prejudice

African American clients have reported racism and prejudice in health care; yet there is limited documentation of the strategies used to cope with these experiences. This study describes African American women's perceptions of prejudice in health care and the strategies used to cope with the experiences. This qualitative study used the constructivist perspective of interpretive interactionism for paradigmatic and methodological guidance. Participants were 20 women ranging from age 26 to 74 years with 50% having a high school education. Individual interviews consisting of five areas were conducted with three instruments measuring ethnic identity, socioeconomic status, and general demographics. The analyses provide two themes: experience with the "White health care system" and strategies for coping with the prejudice, which included getting angry, learning to unlearn, being assertive, and walking away. Consistent with the discussions of race in the United States, racism in health care has become a subtle entity that infuses health care relationships.

Blood pressure reactivity to stress is better for people who recently had penile–vaginal intercourse than for people who had other or no sexual activity

Penile-vaginal intercourse (PVI) but not other sexual behavior is associated with better psychological and physiological function. I examined the relationship of sexual behavior patterns to blood pressure (BP) and its reactivity to stress (public speaking and verbal arithmetic). For a fortnight, 24 women and 22 men used daily diaries to record PVI, masturbation, and partnered sexual behavior in the absence of PVI. Persons who reported PVI (but no other sexual activities) had better stress response (less reactivity and/or lower baseline levels) than persons reporting other or no sexual behaviors. Persons who only masturbated or had partnered sex without PVI had 14 mmHg more systolic BP reactivity than those who had PVI but not the other behaviors. Many variables were examined but failed to confound the observed relationships. The magnitude of the sexual behavior effect on BP reactivity is greater than of other factors in the literature. These findings add to the research corpus on the benefits of PVI (differentiated from other sexual activities).

Interactive effects of avoidant coping and parental hypertension on Rate Pressure Product reactivity in women

BACKGROUND

Previous research suggests that personality, situational context variables, and genes might interact to potentiate cardiovascular stress responses.

PURPOSE

Our purpose is to examine interactive effects of dispositional avoidant coping and parental hypertension on cardiovascular reactivity to three different laboratory stressors.

METHOD

Participants were 63 healthy female students. Stressors were an evaluated videotaped speech, the cold pressor, and viewing of the speech video. Heart rate and blood pressure were continuously recorded during baselines and tasks.

RESULTS

After controlling for age, body mass index, smoking status, reported exercise, alcohol consumption, oral contraceptive use, parental hypertension, and avoidant coping, the interaction term of parental hypertension and avoidant coping was the best predictor of rate pressure product (RPP) reactivity to the speech task and to the video-viewing task. In contrast, reactivity to the cold pressor was not significantly predicted by this interaction term. Furthermore, there were no significant main effects of parental hypertension and avoidant coping on RPP reactivity in any of the tasks. There were no significant interactive effects for diastolic blood pressure.

CONCLUSIONS

Consistent with an interactive model of cardiovascular reactivity, parental hypertension plus avoidant coping led to enhanced RPP reactivity. This effect, however, was only evident during self-threatening stressors. The results suggest that the coincidence of genetic and personality factors might enhance risk for cardiovascular diseases.
