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? Estimated prevalence of sleep problems in children and adolescents ranges from 11% to 47% depending on sample, assessment mode and definition. → Stormark KM 2019

Narrative background synthesis in the introduction, citing prior community surveys; the review-level statement reports a prevalence "ranging from 11% [8] to 47% [9]" across studies. The article attributes these figures to the cited prior studies.
"Sleep problems are common in children [1] and adolescents [2–7],with estimated prevalence ranging from 11% [8] to 47% [9] depending on factors like study sample, mode of assessment [10] and self- [11] vs caregiver [12]-report"
Discussion¶
Related Claims¶
- Frequent daytime sleepiness is associated with impaired academic achievement, attention, and learning motivation in school-aged children
- In the intervention trial, short sleep prevalence fell sharply in delayed-start schools (intervention 2: 40.47% to 11.87%) while sufficient-sleep prevalence remained low overall — a narrower finding that bears on this claim
- Daytime sleepiness is highly prevalent among Chinese school-aged children, affecting 64.44% (sometimes 37.50%, frequently 26.94%) — a narrower finding that bears on this claim
- Only 22.34% of Chinese school-aged children get sufficient sleep (≥10 hours), while 37.96% have short sleep duration (<9 hours) — a narrower finding that bears on this claim
