OBJECTIVE The main purpose of the present study was to calculate percentile curves for total sleep duration per 24 hours, for nighttime and for daytime sleep duration from early infancy to late adolescence to illustrate the developmental course and age-specific variability of these variables among subjects. METHODS A total of 493 subjects from the Zurich Longitudinal Studies were followed using structured sleep-related questionnaires at 1, 3, 6, 9, 12, 18, and 24 months after birth and then… Expand
Sleep Duration From Ages 1 to 10 Years: Variability and Stability in Comparison With Growth
TLDR
Sleep duration during early and middle childhood shows large variability among children, as well as trait-like long-term stability and state-like yearly fluctuations within children. Expand
Breakpoints of time in bed, midpoint of sleep, and social jetlag from infancy to early adulthood.
TLDR
The age around 16-17 years can be considered a remarkable breakpoint when sleep behavior significantly changes back towards slightly longer sleep, less socially jetlagged behavior, and the increase in eveningness is then stopped but not reversed. Expand
Childhood sleep duration and associated demographic characteristics in an English cohort.
TLDR
Given the wide natural variation of sleep in the childhood population, any recommendations on optimal sleep duration at any age must take into account considerable individual variability. Expand
Development of Late Circadian Preference: Sleep Timing From Childhood to Late Adolescence
TLDR
This study found significant continuity in sleep timing from childhood to adolescence over 9 years, indicating that late circadian preference reported in late adolescence begins to manifest in middle childhood. Expand
Longitudinal Assessment of Sleep Trajectories During Early Childhood and Their Association with Obesity.
TLDR
Findings indicate that focusing on sleep behaviors in children before age 3 may be a priority for pediatric providers with a goal of decreasing obesity risk. Expand
Sleep Duration and Sleep Problems in a Representative Sample of German Children and Adolescents
TLDR
Evaluating sleep duration for nighttime sleep from early infancy to late adolescence in a German sample to illustrate the developmental course and age-specific variability of these variables among subjects found age- specific variability of sleep duration as well as sleep difficulties from infancy to adolescence. Expand
Trajectories and stability of self‐reported short sleep duration from adolescence to adulthood
TLDR
Habitual short sleep duration during middle adulthood is not sustained from the time of early adolescence, rather, these trends appear to be formed during early adulthood. Expand
Sleep duration and blood pressure: a longitudinal analysis from early to late adolescence
TLDR
This study found no association between sleep duration at 13 years old and blood pressure at 17 years old in girls, but among males an inverse association was found. Expand
Short sleep duration in middle childhood: risk factors and consequences.
TLDR
Long sleep duration was shown to be an independent risk factor for obesity/overweight and attention deficit / hyperactivity disorder scores (both parent and teachers Conners Rating Scales) did not differ with sleep duration. Expand
Infant night sleep trajectory from age 3-24 months: evidence from the Singapore GUSTO study.
TLDR
The sleep trajectory of Singaporean infants appeared similar to other predominantly Caucasian cohorts for 3-12 months but not for 12-24 months, in which infants from predominantly Caucasian cohort mostly displayed a decreasing or a stable-plateaued trajectory, in concordance with existing studies that suggest that the underlying influences of night sleep shift from predominantly biological influences to increasing environmental influences with age.

Development of sleep patterns in early adolescence
TLDR
The results indicated that nocturnal sleep times decreased, bedtimes were delayed and differences between weekend and school day sleep schedules progressively increased with age, and gender and puberty were both associated with the timing of sleep on weekends. Expand
[The development of sleep behavior within the first 5 years of life].
TLDR
In about half of the children with evening wakefulness and/or night wakening these sleep behaviors were considered as abnormal by the mothers, and the length of day sleep and that of night sleep was negatively correlated between 2 and 5 years. Expand
Sleep ontogenesis revisited: a longitudinal 24-hour home polygraphic study on 15 normal infants during the first two years of life.
TLDR
This study provides three new interesting results related to the maturation of sleep mechanisms and functions: the high stability of the percentage of slow-wave sleep along these 2 years, the presence (from 12 months of age) of a stage 2/REM sleep ratio equal to one, and a sleep change occuring earlier, during the diurnal rather than the nocturnal part of the nycthemere. Expand
Developmental course of nighttime sleep-wake patterns in full-term and premature infants during the first year of life. I.
TLDR
Two groups of infants (40 normal full-term, 24 prematurely born infants) were matched on conceptional age and were studied at seven ages during the first year of life, finding sleep-wake state ontogenesis is comparable in both groups. Expand
Sleep habits and height at ages 5 to 11.
TLDR
It was shown that there was a weak negative association between sleep duration and height, and variation in sleep duration between children is unlikely to have an important influence on growth. Expand
The Development of Children in a Swedish Urban Community. A Prospective Longitudinal Study
TLDR
The sleep behaviour of the children which is reported here was followed up to the age of 3 years, and the length of sleep showed no statistical correlation with a great number of tested environmental factors, including overcrowding and the mother being gainfully employed. Expand
Sleep In The First Year Of Life
TLDR
Sleep pattern related significantly to whether or not mothers found their infants difficult to feed, and introduction of weaning food at an early stage reduced the number of sleep episodes, but increased the average length of each episode. Expand
Sleep patterns in pre-adolescent children: an EEG-EOG study.
TLDR
The typical all-night sleep pattern of the pre-adolescent male was determined by analyzing the simultaneous EEG-EOG tracings of 18 healthy schoolboys by observing the occurrence of a more or less orderly sequence of sleep stages which spontaneously shifted from one stage to another. Expand
Evaluating night wakings in sleep-disturbed infants: a methodological study of parental reports and actigraphy.
TLDR
It is suggested that subjective and objective measures should play a complementary role in the clinical assessment of night-waking problems in early childhood. Expand
Naps in children: 6 months-7 years.
TLDR
Results showed that there were no differences in nap patterns based on gender, ordinal position, whether naps spontaneously disappeared or were stopped by the parents, and the number of naps at 6 months of age. Expand
