身体健康一直与收入和控制感相关联，作者先前证明，身体健康指标的遗传变异随着收入的增加而减少（见W。约翰逊和R. F. Krueger，2004）。在这项研究中，作者使用了来自美国麦克阿瑟基金会中年发展全国调查的719对双胞胎的全国样本，表明身体健康指标（慢性疾病和体重指数）的遗传变异也随着控制感的增加而减少。作者通过展示遗传对控制感和收入的影响在解释身体健康方面的相互作用，整合了收入和控制的研究结果。他们假设，这种相互作用的机制是代谢效率和对压力环境的适应之间已知的生物学关系。
Physical health has been linked consistently with both income and sense of control, and the authors previously demonstrated that genetic variation in physical health measures decreased with increasing income (see W. Johnson & R. F. Krueger, 2004). Using a nationwide sample of 719 twin pairs from the MacArthur Foundation National Survey of Midlife Development in the United States, in this study the authors show that genetic variation in physical health measures (number of chronic illnesses and body mass index) also decreases with increasing sense of control. The authors integrate findings for income and control by demonstrating an interaction between genetic influences on sense of control and income in explaining physical health. They hypothesize that the mechanism underlying the interaction is the known biological relationship between metabolic efficiency and adaptation to stressful environments.
