Predictors of shorter sleep in early childhood.

ABSTRACT:

The aim of this study was to identify socio-demographic and home environmental predictors of shorter sleep in early childhood, and to examine whether effects were mediated by the timing of bedtime or wake time.

Methods

Participants were from Gemini, a British birth cohort of twins, and included 1702 children; one randomly selected from each twin pair.
