Epistemic and Temporal Disjunctions: (Re)Mapping “Suicide Risk” Epigenetics Through Birth Cohorts

The McGill Group for Suicide Studies (MGSS) has garnered significant attention for its epigenetic models of suicide risk. These models suggest that early life adversity may set people on pathways of neurobiological vulnerability and, ultimately, suicide risk, which are correlated with distinctive epigenetic traits. While the core of this epigenetic and neuroscientific research is carried out on the donated brains …

How should we study intergenerational trauma? Reflections on a 30-year birth cohort study in Soweto, South Africa

My parents immigrated to the United States from South Korea in the late 80’s in search of political stability and socioeconomic opportunity. While they did not come with much money or many belongings, as children of survivors of Japanese colonialism and the Korean War, my parents brought with them the heavy burdens of historical trauma from militarized occupation and their …

Human Placenta, Birth Cohorts, and the Production of Epigenetic Knowledge

Precious Material

Over the past decade, the Canadian university-based Epigenetics Lab has become increasingly central to the production of knowledge about human health and development.[1] During my first visit there, Daniel, one of three technicians in the lab, is visibly stressed. He apologizes for not being more relaxed. He has been up all night worried about a shipment of …

Toxicology and the chemistry of cohort kinship

Birth cohort studies are characterized as longitudinal investigations of research subjects with at least one common characteristic, usually being born in the same time and place. Such studies are increasingly common around the world and across a number of disciplines (Gibbon and Pentecost 2019), including toxicology. The small group of approximately twenty reproductive and developmental toxicologists I researched while conducting …

Bioethnography and the Birth Cohort: A Method for Making New Kinds of Anthropological Knowledge about Transmission (which is what anthropology has been about all along)

© Elizabeth F. S. Roberts

These are pots and dishes. They transmit food and love. They transmit lead. They transmit class. They transmit enduring inequality and new forms of environmental degradation. These transmissions are conveyed through food, love, and chemical leaching. These pots are for sale in working class neighborhoods in Mexico City. They are passed around in families. They …

Introduction: Excavating and (re)creating the biosocial; birth cohorts as ethnographic object of inquiry and site of intervention

Longitudinal birth cohorts are increasingly recognised as important for understanding how biological, social and environmental processes interact over time and contribute to health inequalities. Birth cohorts have also become part of global assemblages of knowledge production, particularly in the field of the Developmental Origins of Health and Disease (DOHaD, Gluckman et al. 2016), and act as important technologies of evidence …
