A growing body of research indicates that one's early life experiences may play an important role in regulating patterns of energy intake in adulthood. In particular, adults who grew up under conditions characterized by low socioeconomic status (SES) tend to eat in the absence of hunger (EAH), a pattern that is not generally observed among higher-SES individuals. In the current study, we sought to examine (a) the environmental correlates of low SES that drive the association between low childhood SES and EAH and (b) whether the relationship between these variables is already manifest in children ages 3-14. Results of our study revealed that growing up in low-SES environments predicted less food security, diminished ability to meet financial needs, and less environmental predictability/safety. Further, the results indicated that reduced environmental predictability/safety in the children's environment interacted with children's current energy need to predict eating behavior. Consistent with patterns observed in adults, children from more predictable/safe environments ate food commensurate with their energy need, whereas those from less predictable/safe environments ate comparably high amounts of food across levels of energy need. These results offer needed insights into the development of environmentally-contingent energy-regulation strategies.
越来越多的研究表明,一个人的早期生活经历可能在调节成年后的能量摄入模式方面发挥重要作用。特别是,在社会经济地位(SES)较低的环境中长大的成年人往往在不饥饿时进食(EAH),这种模式在高SES个体中通常不会出现。在当前的研究中,我们试图研究(a)导致儿童时期低SES与EAH之间关联的低SES的环境相关因素,以及(b)这些变量之间的关系在3至14岁的儿童中是否已经显现。我们的研究结果表明,在低SES环境中成长预示着粮食安全较低、满足财务需求的能力下降以及环境可预测性/安全性较低。此外,结果表明,儿童环境中环境可预测性/安全性的降低与儿童当前的能量需求相互作用,以预测饮食行为。与在成年人中观察到的模式一致,来自更可预测/安全环境的儿童进食量与他们的能量需求相称,而来自较不可预测/安全环境的儿童在不同能量需求水平下进食量相对较高。这些结果为环境相关的能量调节策略的发展提供了必要的见解。
