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.
q3 i? In the national cross-sectional survey, mean sleep duration was 9.35±0.77 hours, with only 22.34% of children obtaining sufficient sleep (≥10 hours/day) and 37.96% short sleep (<9 hours/day). → Li Shenghui 2013

q3 · i? · associational · r2
Cross-sectional survey of 20,778 children in eight Chinese cities; sleep duration was parent-reported via the CSHQ, averaging weekday and weekend sleep weighted 5:2. The survey found "22.34% of children got sufficient sleep (≥10 hours per day)" and a mean sleep duration of 9.35±0.77 hours.
"The mean sleep duration was 9.35±0.77 hours. 22.34% of children got sufficient sleep (≥10 hours per day)."
Discussion¶
Related Claims¶
- Daytime sleepiness is highly prevalent among Chinese school-aged children, affecting 64.44% (sometimes 37.50%, frequently 26.94%) — related
- 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 — related
- Delaying school start time by 30 or 60 minutes increased children's sleep duration and reduced daytime sleepiness over two years — 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
- Sleep and consolidation support semantic memory development, suggesting delayed school start times may benefit memory — related
- Shorter sleep duration is associated with more screen time in children aged 0–4 years (5 of 5 studies) — related
- Frequent daytime sleepiness is associated with impaired academic achievement, attention, and learning motivation in school-aged children — related
- Sleep problems are common in school-aged children, with prevalence estimates ranging widely depending on assessment mode and definition — a broader claim this one bears on
- Fatigue depends on age, sex, lesson length and number, time of day, weekday, recesses, holidays, rest, sleep, nature of work, school program, and teacher personality (Offner's laws of fatigue) — related
