Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Sleep duration at age 4 was inversely associated with television viewing and computer use at age 6. → Chaput JP 2017
q2 i2 Cross-sectionally, short sleep was associated with TV viewing (OR = 1.65 in boys) and with ≥4 h/day TV (OR = 1.91). → Chaput JP 2017 (2)
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? · associational · r?
Longitudinal study (n = 2984) in the review's sedentary behaviour section; GRADE "very low" due to parent-reported sleep. Printed β coefficients are unstandardised, so impact is null.
"Sleep duration at 4 years of age was inversely associated with television viewing (β = −0.07, p = 0.003) and computer use ( β = −0.04, p = 0.001) at 6 years of age [ 22]."

q2 · i2 · review · r3
One of four cross-sectional studies (42,751 participants combined) in the sedentary behaviour synthesis; GRADE "very low". Printed odds ratios OR = 1.91 and OR = 1.62 support impact 2.
"Short sleep duration was associated with longer hours spent watching television (OR = 1.91, 95% CI 1.26 – 2.90 for ≥4 h/day) and playing computer games (OR = 1.62, 95% CI 1.18 – 2.23 for ≥2 h/day) compared to not watching/playing [ 80]."
Discussion¶
Related Claims¶
- Shorter sleep duration is associated with higher adiposity in children aged 0–4 years, though evidence quality is low
- Shorter sleep duration is associated with higher injury risk in children aged 0–4 years, though evidence is limited (2 of 3 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
- A consistent bedtime routine is associated with better sleep outcomes in young children, with a dose-dependent relationship between nights per week of routine adherence and sleep benefits
- Only 22.34% of Chinese school-aged children get sufficient sleep (≥10 hours), while 37.96% have short sleep duration (<9 hours) — related
