Background: Exposure to high levels of maternal stress and ineffective maternal–child engagement (MC-E) may adversely affect child health-related outcomes.
Objective: The aim of this study was to examine the impact of maternal stress and MC-E on maternal and child biological responses (salivary cortisol and testosterone) and child health outcome in mother–child dyads of preschool children (3–5.9 years) in a low socioeconomic setting.
Methods: Observational and biobehavioral data were collected from 50 mother–child dyads in a preschool setting. Assessments included maternal stress with the Perceived Stress Scale, child health outcomes with the Pediatric Quality of Life Inventory, and MC-E with videotaped mother–child interactions and scored with the Keys to Interactive Parenting Scale. Morning and evening saliva samples were collected from mother and child for biological assays.
Results: Maternal stress was negatively correlated with MC-E (r = −.32, p < .05) and child health outcome (r = −.33, p < .05). Lower levels of MC-E predicted higher morning cortisol (p = .02) and higher morning and bedtime testosterone levels in children (p = .03 and p = .04, respectively). Child biological responses did not predict child health outcome.
Discussion: Maternal stress and MC-E during mother–child interactions play a significant role in the regulation of child stress physiology and child health outcome. Elevated cortisol and testosterone related to high maternal stress and low MC-E may increase the child's vulnerability to negative health outcomes—if sustained. More biobehavioral research is needed to understand how parent–child interactions affect child development and health outcomes in early childhood.
