以前关于皮质醇输出和社会经济地位（SES）的证据是混合的，研究发现较低的SES可能与较高或较低的皮质醇输出有关，也有报道称无关联。我们假设，这些不一致可能是由于一个潜在的曲线，倒U型的关联模式，低收入是与低和高皮质醇输出的可能性增加。我们在雅芳父母和儿童纵向研究（N = 803）中测试了家庭收入和皮质醇指数之间的曲线联系。母亲报告的家庭收入时，研究儿童33和47个月的年龄平均估计幼儿家庭收入。三个皮质醇指数来自青春期（15.5岁）收集的样本：皮质醇觉醒反应（CAR），皮质醇曲线下面积（AUC）和昼夜皮质醇斜率。正如假设的那样，CAR与童年收入呈曲线倒U型关系，低童年收入与最低和最高汽车相关。这些研究结果表明，在低SES和CAR的先前研究结果的差异可能是由于曲线的关联模式。然而，童年收入与青少年皮质醇昼夜斜率或AUC无显著相关性。未来的工作应该澄清的因素，可能倾向于高与低CAR在儿童时期给予同等的低SES。
Previous evidence on cortisol output and socioeconomic status (SES) has been mixed, with studies finding that lower SES can be associated with higher or lower cortisol output, and null associations have also been reported. We hypothesized that these inconsistencies may be due to an underlying curvilinear, inverted-U pattern of association, such that low income is related to increased likelihood of both low and high cortisol output. We tested these curvilinear links among family income and cortisol indices in the Avon Longitudinal Study of Parents and Children (N = 803). Maternal reports of family income when the study children were 33 and 47 months of age were averaged to estimate early-childhood family income. Three cortisol indices were derived from samples collected in adolescence (15.5 years of age): the cortisol awakening response (CAR), area under the curve (AUC) cortisol, and the diurnal cortisol slope. As hypothesized, the CAR exhibited a curvilinear, inverted-U relation with childhood income, with low childhood income being associated with both the lowest and the highest CARs. These findings suggest that discrepancies in prior findings on low SES and the CAR may be due to curvilinear patterns of association. However, childhood income was not significantly associated with adolescent cortisol diurnal slope or AUC. Future work should clarify the factors that might predispose to high versus low CAR given equivalent low SES in childhood.
