Exploring Income Inequality as a Predictor of Mental, Emotional, Developmental, Behavioural and Physical Health Outcomes in US Children

This cross-sectional study shows that household income predicts children's overall, physical and mental, emotional, developmental or behavioural (MEDB) health outcomes. Using recent national data, we found that income-related disparities were evident across multiple conditions, underscoring the need for interventions that address both healthcare access and broader socio-economic factors. Children from low-income households face higher health risks. Policies that expand preventive care, strengthen family supports and reduce structural inequities are critical to improving child health equity.
