Children raised in families with low socioeconomic status (SES) go on to have high rates of chronic illness in adulthood. However, a sizable minority of low-SES children remain healthy across the life course, which raises questions about the factors associated with, and potentially responsible for, such resilience. Using a sample of 1,205 middle-aged Americans, we explored whether two characteristics--upward socioeconomic mobility and early parental nurturance--were associated with resilience to the health effects of childhood disadvantage. The primary outcome in our analyses was the presence of metabolic syndrome in adulthood. Results revealed that low childhood SES was associated with higher prevalence of metabolic syndrome at midlife, independently of traditional risk factors. Despite this pattern, half the participants raised in low-SES households were free of metabolic syndrome at midlife. Upward social mobility was not associated with resilience to metabolic syndrome. However, results were consistent with a buffering scenario, in which high levels of maternal nurturance offset the metabolic consequences of childhood disadvantage.
在社会经济地位(SES)较低的家庭中长大的儿童,成年后患慢性病的几率较高。然而,仍有相当一部分 SES 较低的儿童在整个生命周期中保持健康,这引发了人们对与这种韧性相关的因素以及可能导致这种韧性的因素的疑问。本研究使用了 1205 名美国中年人的样本,探讨了两个特征——社会经济地位的提升和早期父母的养育——是否与抵御童年逆境对健康的影响有关。我们分析的主要结果是成年后患代谢综合征的情况。研究结果表明,较低的儿童 SES 与中年时期代谢综合征的发病率较高有关,而与传统的风险因素无关。尽管存在这种模式,但一半在 SES 较低家庭中长大的参与者在中年时期没有代谢综合征。社会地位的提升与对代谢综合征的抵抗力无关。然而,结果与缓冲情景一致,即母亲的高度养育抵消了童年逆境的代谢后果。
