Many hormones play important roles in both pubertal development and sleep regulation. Because of the possible consequences of impaired sleep, including impaired health and cognition, it is important to examine whether an association between pubertal stage and sleep exists. The aim of this analysis is to examine the association between sleep and adolescent growth and developmental stage in a large sample of adolescents ages 12-16 years from a nationally representative longitudinal study. This analysis used the public-use data set of the National Longitudinal Study of Adolescent Health, an extensive survey of health and behavior among adolescents in the United States. The study included two interviews approximately 1 year apart. Pubertal development, sleep variables, and height are self-reported. Pubertal development scores were calculated by summing responses to three questions for each sex. The sleep variables include sleep duration, frequent insomnia (once/week or more), frequently waking tired (once/week or more), and insufficient sleep. The results indicate a sex difference in the association between sleep problems and pubertal development. Among females, there was a significant increase in sleep problems with increasing pubertal development score, but not among males. The negative association between sleep duration and pubertal development score, however, was significant in both males and females. There is no association between sleep duration and height velocity (inches/year) in this sample. The results, which are based on a large sample size, warrant further examination with more objective measures into the association between sleep and growth and development among adolescents.
