Hispanic children obtain significantly less sleep than Caucasian children at phase 1, but this difference is no longer present 5 years later in phase 2. There is no significant difference seen in weekend sleep duration between Hispanic and Caucasian children. Data are presented as B coefficient (standard error (SE)).
