To explore the associations among ethnicity, educational attainment, and cortisol secretion.
Participants include 63 white (n = 31) and African-American (n = 32) adult men and women. Subjects provided salivary cortisol samples immediately upon awakening and again, 30 minutes later.
Analyses adjusted for relevant covariates revealed a steeper awakening response among whites with higher education compared to other groups. Cortisol levels were significantly lower among African-American participants with lower levels of education. All effects were independent of perceived stress.
These preliminary findings demonstrate significant ethnic and education-related differences in awakening cortisol secretion responses. Our data highlight the importance of considering ethnicity and the moderating effects of social class when examining the associations among social contextual factors and cortisol secretion.
探讨种族、教育程度与皮质醇分泌之间的关联。
参与者包括63名成年男性和女性，其中白人31名，非裔美国人32名。研究对象在醒来后立即提供唾液皮质醇样本，并在30分钟后再次提供。
对相关协变量进行调整后的分析显示，与其他组相比，受教育程度较高的白人觉醒反应更为强烈。教育程度较低的非裔美国参与者的皮质醇水平显著较低。所有影响均与感知压力无关。
这些初步研究结果表明，在觉醒皮质醇分泌反应方面存在显著的种族和教育相关差异。我们的数据强调了在研究社会环境因素与皮质醇分泌之间的关联时，考虑种族和社会阶层调节作用的重要性。
