Socioeconomic Status and the Intergenerational Transmission of Health Inequalities: Mechanisms, Pathways, and Implications

Abstract

Health inequalities rooted in socioeconomic disadvantage do not merely affect individuals during their own lifetimes—they tend to replicate across generations, producing persistent disparities that are difficult to reverse. This paper examines the mechanisms through which parental socioeconomic status (SES) shapes offspring health outcomes, drawing on evidence from epidemiology, developmental psychology, and social stratification research. Rather than attributing intergenerational health transmission to any single factor, we argue that it emerges from a confluence of material deprivation, psychosocial stress, health-related behaviors, and biological embedding processes that operate across different developmental periods. Parental SES influences children’s health not only through differential access to medical care and nutrition but also via the quality of early caregiving environments, parental stress and mental health, and the transmission of health literacy and behavioral norms. These pathways are further moderated by neighborhood contexts, educational systems, and broader policy environments that either reinforce or disrupt inherited disadvantage. The paper concludes by discussing the implications of these findings for intervention design and social policy, emphasizing that efforts to break the cycle of health inequality must address both material conditions and the psychosocial dynamics through which disadvantage becomes biologically embodied.
