q2 · i1 · associational · r1

Longitudinal study (n = 23) in the review's growth section; GRADE downgraded to "very low" for serious risk of bias. Printed odds ratios: "1.20 for each additional hour of sleep" and "1.43 for each additional sleep bout".

"Saltatory length growth was associated with increased total daily sleep hours ( p < 0.001) and number of sleep bouts ( p = 0.001)."

Discussion¶

Related Claims¶

• Shorter sleep duration is associated with higher adiposity in children aged 0–4 years, though evidence quality is low
• 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
• 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
