Racial Differences in Reported Napping and Nocturnal Sleep in 2- to 8-Year-Old Children

Abstract

There are remarkable racial differences in reported napping and nighttime sleep patterns beginning as early as age 3 and extending to at least 8 years of age. These differences are independent of commonly investigated demographic factors. Differences in napping behavior do not seem to have psychosocial significance in a sample of preschool children.
