社会阶层歧视在世界各地的许多社会都很明显，但人们对它对穷人的影响或它作为社会经济地位与健康之间联系的解释变量的作用知之甚少。目前的研究测试了感知歧视在多大程度上解释了身体健康的社会经济梯度。参与者为252名青少年（51%男性，49%女性;平均年龄= 17.51岁，SD = 1.03岁），他们参加了一项正在进行的纵向研究的第3波，重点是农村贫困的发展后果。身体健康被操作化为非稳态负荷，这是一种对身体的累积磨损和撕裂的测量，这种磨损和撕裂是由对压力做出反应的生理系统过度激活引起的。调解分析表明，13%的贫困对非稳态负荷的影响是由感知歧视解释的。研究结果表明，社会阶层歧视是贫困影响身体健康的一个重要机制。
Social-class discrimination is evident in many societies around the world, but little is known about its impact on the poor or its role as an explanatory variable in the link between socioeconomic status and health. The current study tested the extent to which perceived discrimination explains socioeconomic gradients in physical health. Participants were 252 adolescents (51% male, 49% female; mean age = 17.51 years, SD = 1.03 years) who participated in Wave 3 of an ongoing longitudinal study focusing on the developmental consequences of rural poverty. Physical health was operationalized as allostatic load, a measure of cumulative wear and tear on the body caused by overactivation of physiological systems that respond to stress. Mediation analyses suggested that 13% of the effect of poverty on allostatic load is explained by perceived discrimination. The findings suggest that social-class discrimination is one important mechanism behind the influence of poverty on physical health.
