Purpose of reviewTo examine the five domains of social determinants of health – economic stability, education access, healthcare access and quality, neighborhood and built environment, and social and community context – and how these relate to caregiver stress in under-resourced populations.Recent findingsSocioeconomic and family factors are increasingly understood as drivers of child health. Caregiver stress can impact family stability and child wellbeing. Immigrant parents, caregivers of children with medical complexity, and adolescent parents experience stressors due to the unique needs of their families. These groups of parents and caregivers also face various challenges identified as social determinants of health. Interventions to mitigate these challenges can promote resilience, care coordination, and community-based supports.SummaryCurrent research describes caregiver stress in key populations, how caregiver stress affects children, and approaches to minimize and mitigate these effects. Pediatric providers can implement best practices to support families who are navigating stress due to caregiving and social determinants of health.
