OBJECTIVE Research on subjective social status (SSS) and inflammation risk suffers from a lack of cross-cultural data as well as inconsistent findings between SSS and the biomarker C-reactive protein (CRP). The current study addressed these issues by examining possible cultural differences in the SSS-CRP link with anger control as an underlying mechanism while controlling for potential confounds such as wealth, education, and health factors. METHOD Participants comprised 1,435 adults from the Biomarker Project of the MIDUS (American) and MIDJA (Japanese) studies. Participants' SSS and tendency to control anger were assessed through surveys, and their CRP levels were measured through fasting blood samples. RESULTS Results showed that for Americans, CRP levels increased as SSS decreased, but for the Japanese, there was no relationship between SSS and CRP. Furthermore, this moderating effect of culture was mediated by anger control such that Americans controlled their anger less as SSS decreased, which then predicted higher levels of CRP, whereas the Japanese controlled their anger less as SSS increased, but this relationship did not predict CRP levels. These findings were specific to anger control (and not other varieties of anger) and robust to adjustment for a variety of potential confounds. CONCLUSIONS Our findings demonstrate that culture exerts a moderating effect on the relationship between SSS and CRP, and this effect occurs through cultural differences in how SSS relates to anger control. The current study also highlights the need to consider cultural factors and psychosocial processes in further research on SSS and health.

主观的社会地位和炎症：文化和愤怒控制的作用。

目的关于主观社会状态（SSS）和炎症风险的研究因缺乏跨文化数据以及SSS与生物标志物C反应蛋白（CRP）之间不一致的发现而受到困扰。当前的研究通过检查SSS-CRP中可能存在的文化差异以及将愤怒控制作为潜在机制，同时控制了诸如财富，教育和健康因素之类的潜在问题，从而解决了这些问题。方法参与者包括来自MIDUS（美国）和MIDJA（日本）研究的生物标志物计划的1,435名成人。通过调查评估参与者的SSS和控制愤怒的倾向，并通过空腹血液样本测量其CRP水平。结果结果表明，美国人的CRP水平随SSS的降低而增加，而对于日本人，SSS和CRP之间没有关系。此外，文化的这种调节作用是通过控制愤怒来调节的，因此美国人随着SSS的降低而减少了对愤怒的控制，从而预示了CRP的升高，而日本人随着SSS的升高却降低了对愤怒的控制，但这种关系并不能预测CRP的水平。 。这些发现特定于愤怒控制（而不是其他种类的愤怒），并且对于调整各种潜在的混杂因素具有鲁棒性。结论我们的研究结果表明，文化对SSS和CRP之间的关系起调节作用，而这种影响是通过SSS与愤怒控制相关的文化差异而产生的。当前的研究还强调了在对SSS和健康进行进一步研究时需要考虑文化因素和社会心理过程。
