Previous studies conducted in Western cultures have shown that negative emotions predict higher levels of pro-inflammatory biomarkers, specifically interleukin-6 (IL-6). This link between negative emotions and IL-6 may be specific to Western cultures where negative emotions are perceived to be problematic and thus may not extend to Eastern cultures where negative emotions are seen as acceptable and normal. Using samples of 1044 American and 382 Japanese middle-aged and older adults, we investigated whether the relationship between negative emotions and IL-6 varies by cultural context. Negative emotions predicted higher IL-6 among American adults, whereas no association was evident among Japanese adults. Furthermore, the interaction between culture and negative emotions remained even after controlling for demographic variables, psychological factors (positive emotions, neuroticism, extraversion), health behaviors (smoking status, alcohol consumption), and health status (chronic conditions, BMI). These findings highlight the role of cultural context in shaping how negative emotions affect inflammatory physiology and underscore the importance of cultural ideas and practices relevant to negative emotions for understanding of the interplay between psychology, physiology, and health.

:以前在西方文化中进行的研究表明,负面情绪预示着较高的促炎性生物标志物,特别是白介素6(IL-6)。消极情绪与IL-6之间的这种联系可能特定于西方文化,在该文化中,消极情绪被认为是有问题的,因此可能不会扩展到东方文化,在东方文化中,消极情绪被视为可以接受并且是正常的。我们使用1044名美国人和382名日本中年和老年人的样本,调查了负面情绪与IL-6之间的关系是否因文化背景而异。负面情绪预示着美国成年人IL-6升高,而日本成年人却没有明显的关联。此外,即使在控制了人口统计学变量,心理因素(正性情绪,神经质,外向性),健康行为(吸烟状况,饮酒)和健康状况(慢性状况,BMI)之后,文化与负面情绪之间的相互作用仍然存在。这些发现凸显了文化背景在塑造负面情绪如何影响炎症生理方面的作用,并强调了与负面情绪相关的文化观念和实践对于理解心理学,生理学和健康之间相互作用的重要性。
