Socioeconomic status (SES) gradients may not be static across the lifespan, but instead may vary in strength across different life stages. This study examined the periods in childhood when SES and health relationships emerge and are strongest among US children. Data came from the National Health Interview Survey, 1994, a cross sectional, nationally representative sample of 33,911 US children ages 0-18. Parents were asked about family SES and child health status. Global health measures included overall ratings of child health, activity and school limitations. Acute conditions included childhood injuries and respiratory illnesses. For all global child health measures, lower family SES was associated with poorer child health in a gradient fashion (P<. these differences did not vary across age. for specific conditions interaction effects of ses with age were found revealed that injury and acute respiratory illness expected gradients poorer outcomes evident during adolescence. in contrast had a reverse gradient early childhood. sum global child health measures associations lower throughout childhood suggest factors do change care quality may best explain overall status. however the relationship between low poor appears most consistently this suggests normal development-related changes adolescence such as increasing peer group affiliation help gradients. patterns are important to understand optimally timing interventions reduce disparities us children health.>
