ABSTRACT
OBJECTIVE: Exposure to maternal stress in early childhood can increase risk for learning and behavior challenges. We sought to gain in-depth understanding of how mothers perceive stressors to impact child wellbeing and identify mothers' strategies for navigating stressors with their young children. METHODS: We recruited English- and Spanish-speaking mothers from a primary care clinic serving predominantly publicly insured children. Twenty-one mothers (aged >18 years) of children (aged 6-29 months) participated in in-depth, semi-structured interviews to discuss their experiences and beliefs regarding stress and parenting. Interviews were recorded, transcribed verbatim, and analyzed using the constant comparative method associated with a grounded theory approach. RESULTS: We developed the following hypothesized explanatory model based on our key thematic findings: Mothers described a dyadic model of stress, whereby both their children's and their own experiences of and responses to stressors are interdependent. Mothers use preventive and responsive buffering to mitigate the impact of stress on their children; however, their access to resources, including social and financial support, shapes their capacity for implementing such strategies. Affection and other forms of relational support may function to protect against the negative impacts of stress. CONCLUSION: In the setting of poverty-related chronic stressors, mothers play an active role in mitigating the impact of stress on their children's wellbeing through responsive caregiving. Policies aimed at reducing poverty-related stress exposures and experiences among low-income families may be key interventions for promoting responsive caregiving during a critical time in child development.
ABSTRACT
The human brain develops through a complex interplay of genetic and environmental influences. During critical periods of development, experiences shape brain architecture, often with long-lasting effects. If experiences are adverse, the effects may include the risk of mental and physical disease, whereas positive environments may increase the likelihood of healthy outcomes. Understanding how psychosocial stress and adverse experiences are embedded in biological systems and how we can identify markers of risk may lead to discovering new approaches to improve patient care and outcomes. Biomarkers can be used to identify specific intervention targets and at-risk children early when physiological system malleability increases the likelihood of intervention success. However, identifying reliable biomarkers has been challenging, particularly in the perinatal period and the first years of life, including in preterm infants. This review explores the landscape of psychosocial stress and adverse experience biomarkers. We highlight potential benefits and challenges of identifying risk clinically and different sub-signatures of stress, and in their ability to inform targeted interventions. Finally, we propose that the combination of preterm birth and adversity amplifies the risk for abnormal development and calls for a focus on this group of infants within the field of psychosocial stress and adverse experience biomarkers. IMPACT: Reviews the landscape of biomarkers of psychosocial stress and adverse experiences in the perinatal period and early childhood and highlights the potential benefits and challenges of their clinical utility in identifying risk status in children, and in developing targeted interventions. Explores associations between psychosocial stress and adverse experiences in childhood with prematurity and identifies potential areas of assessment and intervention to improve outcomes in this at-risk group.
