Why socioeconomic status affects the health of children a psychosocial perspective

This article provides an overview of research on socioeconomic status (SES) and physical health in childhood. SES has a gradient relationship with children's health, such that for each incremental increase in SES, there is a comparable benefit in children's health. In this article, I discuss psychosocial mechanisms underlying this association and argue that it is important to utilize knowledge about how the relationship between SES and health changes with age to inform a developmentally plausible search for mediators of this relationship. Furthermore, SES at different points in a child's lifetime may have different effects on health. I advocate an interdisciplinary approach to searching for mediators that would allow researchers to understand how characteristics of society, the neighborhood, the family, and the individual child are involved in the processes linking SES and children's health.
