The relationship between low socioeconomic status (SES) and poor health outcomes has been consistently demonstrated across the lifespan.1,2 In this issue of Archives of Pediatrics & Adolescent Medicine, Singh and Evans3 describe a study that investigated relationships between neighborhood SES and exercise testing in children. The authors found that children from neighborhoods with low SES exercised for shorter duration. Heart rate recovery was also delayed in children from neighborhoods with low SES who had high body mass indexes (calculated as weight in kilograms divided by height in meters squared). These findings are important for a number of reasons.
