儿童贫困与儿童时期和以后生活中的许多生理和心理障碍有关。在这里报告的这项研究中，我们表明，从出生到9岁的儿童在贫困中度过的比例与17岁青少年的过重的变态负荷有关，变态负荷是慢性生理压力的标志。此外，这种预期的纵向关系受到13岁时累积风险暴露的影响。早期生活在贫困中的时间越长，暴露在累积风险中的风险就越大。这反过来又会导致过高的非稳态负荷。多种心理、生物学和神经学途径可能解释了心理和生理疾病的社会模式。
Childhood poverty is linked to a host of physical and psychological disorders during childhood and later in life. In the study reported here, we showed that the proportion of childhood spent in poverty from birth to age 9 was linked to elevated allostatic load, a marker of chronic physiological stress, in 17-year-olds. Furthermore, this prospective longitudinal relationship was mediated by cumulative risk exposure at age 13. The greater the duration of early life spent in poverty, the greater the exposure to cumulative risk. This, in turn, leads to elevated allostatic load. Multiple psychological, biological, and neurological pathways likely account for the social patterning of psychological and physical disease.
