Plan of Analysis for the Study Maternal Hair Cortisol Concentration Trajectories Throughout Pregnancy and Adverse Childhood Experiences

This study outlines its preregistered plan for analyzing maternal hair cortisol concentration during pregnancy and subsequent childhood outcomes due to adverse childhood experiences, detailing the research questions, hypotheses, and statistical methods, with results not yet reported.

This study observed that cortisol concentrations in hair, indicating prolonged stress, are correlated between mothers and young children, suggesting potential heritable traits or maternal influence.

This study observed that hair cortisol levels increased during pregnancy and positively correlated with certain systemic cytokines postpartum, suggesting potential associations with perinatal outcomes.

This study found that sampling hair for cortisol analysis in mother-toddler dyads living in low-income U.S. homes is feasible, with 66% of approached dyads participating.
