Evidence¶

Chaput JP 2017¶

Chaput JP, Gray CE, Poitras VJ, Carson V, Gruber R, Birken CS, MacLean JE, Aubert S, Sampson M, Tremblay MS. (2017). Systematic review of the relationships between sleep duration and health indicators in the early years (0–4 years). BMC Public Health 17(Suppl 5):855. https://doi.org/10.1186/s12889-017-4850-2

q2 · i? · review · r3

Narrative synthesis of 13 longitudinal studies (31,482 participants) in the review's adiposity section; GRADE quality remained "low". The review reports "10 reported that shorter sleep duration was associated with adiposity gain".

"Among the 13 longitudinal studies, 10 reported that shorter sleep duration was associated with adiposity gain [17– 26], 2 reported null findings [27, 28], and 1 reported that longer sleep duration predicted adiposity gain [29]."

q2 · i? · review · r3

Narrative synthesis of 18 cross-sectional studies (30,829 participants); GRADE quality "low". The review reports "10 reported a significant association between shorter sleep duration and adiposity".

"Among the 18 cross-sectional studies, 10 reported a significant association between shorter sleep duration and adiposity [23, 26, 30– 37], 7 reported null findings [24, 25, 27, 28, 38– 40], and 1 reported that sleep dur-ation was unfavourably associated with adiposity [41]."

Discussion¶

Related Claims¶

• Longer sleep duration is associated with linear growth in infants, with small printed odds ratios
• Shorter sleep duration is associated with higher injury risk in children aged 0–4 years, though evidence is limited (2 of 3 studies)
• Shorter sleep duration is associated with more screen time in children aged 0–4 years (5 of 5 studies)
• Evidence on sleep duration and cognitive development in children aged 0–4 years is mixed, with no consistent association
• Sleep duration shows no association with gross and fine motor skills in children aged 0–4 years
• Short sleep duration at age 3 was not associated with quality of life at about age 13 — related
• Short sleep duration (<9 hours) at follow-up is associated with impaired academic achievement, while baseline sleep duration did not significantly predict later school performance — related
• Children who slept <10 hours/day at ages 3-4 years had worse maternal-reported executive function and behavioral difficulties at age 7 than children with age-appropriate sleep — related
