摘要

目的:最近的理论研究表明,美国黑人和白人的情绪表达方式可能有所不同,美国黑人更频繁地使用表达性抑制来调节情绪和避免冲突。先前的研究将表达性抑制的使用与心血管疾病风险的增加联系起来,这表明表达性抑制使用方面的种族差异可能是种族主义 "深入皮肤 "并造成健康差异的机制之一:为了研究表达抑制和血压(衡量心血管疾病风险的指标)的种族差异,我们使用了来自美国中年(MIDUS)纵向研究的两组美国黑人和白人的自我报告和面部肌电图(fEMG)数据(MIDUS 2,n = 271,34.7% 为黑人,收集时间为 2004-2009 年;MIDUS Refresher 1,n = 114,31.6% 为黑人,收集时间为 2012-2016 年;总人数 = 385,33.9% 为黑人):结果:美国黑人比美国白人更经常进行表达性抑制(t(260.95) = 2.18,p = .002),并且在负面图像中表现出较少的皱纹肌肌电图活动(t(969) = 2.38,pFDR = .026)。只有美国黑人在负像时较少的皱纹肌活动与较高的收缩压有关(b = -4.63,t(375) = 2.67,p = .008):总之,研究结果与理论观点一致,即美国黑人更频繁地进行表达性抑制,这反过来又与较高的心血管风险有关。还需要进行更多的研究来进一步验证这一说法,特别是在现实世界的背景下和对表达性抑制的即时使用情况的自我报告中。

Differences in Emotion Expression, Suppression, and Cardiovascular Consequences Between Black and White Americans in the Midlife in the United States (MIDUS) Study.

Objective: Recent theoretical work suggests that the expression of emotions may differ among Black and White Americans, such that Black Americans engage more frequently in expressive suppression to regulate emotions and avoid conflict. Prior work has linked expressive suppression usage with increases in cardiovascular disease risk, suggesting that racialized differences in expressive suppression usage may be one mechanism by which racism "gets under the skin" and creates health disparities.

Method: To examine racialized differences in expressive suppression and blood pressure (a measure of cardiovascular disease risk), we used self-report and facial electromyography (fEMG) data from two cohorts of Black and White Americans from the Midlife in the United States (MIDUS) longitudinal study (MIDUS 2, n = 271, 34.7% Black, collected from 2004 to 2009; MIDUS Refresher 1, n = 114, 31.6% Black, collected from 2012 to 2016; total N = 385, 33.9% Black).

Results: Black Americans reported engaging in expressive suppression more frequently than White Americans ( t (260.95) = 2.18, p = .002) and showed less corrugator fEMG activity during negative images ( t (969) = 2.38, pFDR = .026). Less corrugator activity during negative images was associated with higher systolic blood pressure only for Black Americans ( b = -4.63, t (375) = 2.67, p = .008).

Conclusion: Overall, results are consistent with theoretical accounts that Black Americans engage more frequently in expressive suppression, which in turn is related to higher cardiovascular risk. Additional research is needed to further test this claim, particularly in real-world contexts and self-reports of in-the-moment usage of expressive suppression.

期刊介绍: Psychosomatic Medicine is the official peer-reviewed journal of the American Psychosomatic Society. The journal publishes experimental, clinical, and epidemiological studies on the role of psychological and social factors in the biological and behavioral processes relevant to health and disease. Psychosomatic Medicine is an interdisciplinary peer-reviewed journal devoted to high-quality science on biobehavioral mechanisms, brain-behavior interactions relevant to physical and mental disorders, as well as interventions in clinical and public health settings. Psychosomatic Medicine was founded in 1939 and publishes interdisciplinary research articles relevant to medicine, psychiatry, psychology, and other health-related disciplines. The print journal is published nine times a year; most articles are published online ahead of print. Supplementary issues may contain reports of conferences at which original research was presented in areas relevant to the psychosomatic and behavioral medicine.
