Up to 25% of new mothers experience postpartum depression, a condition that can significantly impact their parenting and the emotional development of their children. A recent study from the University of Illinois Urbana-Champaign sheds light on the long-term effects of early maternal depression, emphasizing the importance of providing adequate support to mothers facing mental health challenges.
The study, led by Samantha Iwinski, a postdoctoral research associate in the Department of Human Development and Family Studies, focused on understanding how early postpartum depression affects children’s emotional wellbeing and behavior. Specifically, the research explored its influence on children’s executive function and their tendency toward emotional overeating.
“Emotional overeating refers to using food to cope with stress or emotions rather than eating for hunger. When children are unable to express their emotions adequately, they may resort to food as a coping mechanism during stressful situations,” Iwinski explained.
The study used data from the Midwest STRONG Kids2 project, which examines how biological factors interact with the family environment to influence children’s eating habits. Participants were mothers who filled out questionnaires about their postpartum depression levels at six weeks, their children’s emotional functioning at 24 months, and their children’s eating behavior at 48 months.
The researchers utilized the biopsychosocial pathways model to analyze the data. This model examines how biological, psychological, and social factors intersect to influence health outcomes, including self-regulation of appetite. In particular, the study highlighted postpartum depression as a critical social factor that predicts emotional overeating in children, with psychological processes playing a key mediating role.
Almost 12% of mothers in the study were identified as having postpartum depression. The findings showed that maternal depression at six weeks had a negative impact on children’s executive function, particularly in areas of inhibition and emotional control at 24 months, as well as a tendency for overeating at 48 months.
“Inhibition refers to a child’s ability to control attention, behavior, and thoughts. For example, a child may focus on their homework instead of being distracted by the TV. Emotional control is about regulating responses, like crying, in reaction to distress,” Iwinski explained.
The study also found direct correlations between maternal postpartum depression and children’s overeating, in addition to the indirect effects through executive functioning. Mothers suffering from postpartum depression often show less responsiveness to their children’s emotional and cognitive needs, which can hinder healthy development and self-regulation. Additionally, mothers with depression may exhibit irregular eating patterns, modeling unhealthy behavior for their children.
The researchers stress the importance of early intervention and mental health support for mothers. “Supporting maternal mental health is crucial for the well-being of both the mothers and their children,” Iwinski said. “Identifying depression early allows families to learn healthy strategies for managing emotions, such as mindfulness, play, or open conversations.”
Teachers and other supportive adults can also play a vital role in supporting families. They can observe eating behaviors and emotional responses in children, using these insights to encourage alternative coping mechanisms and fostering a collaborative effort to address emotional well-being within the family.
This study underscores the lasting impact of maternal mental health on children’s development and highlights the need for early identification and comprehensive support systems for struggling families.
