Title / Titel	Sleep duration from infancy to adolescence
PDF	Abstract (PDF, 14 KB)
Summary / Zusammenfassung	The main purpose of this study was to calculate percentile curves for total sleep duration, for nighttime and for daytime sleep duration from infancy to late adolescence to illustrate the developmental course and age-specific variability of these variables. 493 subjects from the Zurich Longitudinal Studies were followed using structured sleep related questionnaires from 1 month to 16 years. Total sleep duration decreased from an average of 14.2 hours at 6 months to an average of 8.1 hours at 16 years. The variance was large at all ages. There was a significant generational trend because of increasingly later bedtime but unchanged wake time across decades.
