Satisfactory sleep quality is associated with a lower risk of adolescent idiopathic scoliosis in Shanghai school students.
In a cross-sectional study of 5,026 students aged 9-15 in Shanghai, satisfactory sleep quality showed a protective association against screening-detected adolescent idiopathic scoliosis (AIS). The IPW-adjusted estimated population prevalence of AIS was 3.8%, with 162 confirmed cases. Multivariable logistic regression identified sleep quality as one of several modifiable factors associated with AIS.

Satisfactory sleep quality is associated with a lower risk of adolescent idiopathic scoliosis in Shanghai school students. The current body of evidence comprises 1 study. EvidenceHub rates the overall confidence at 34/100 (low).
The Claim
Satisfactory sleep quality is associated with a lower risk of adolescent idiopathic scoliosis in Shanghai school students.
This conclusion is most relevant to: School students aged 9-15 years in Shanghai, China (n=5,026 from six schools in five districts).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Prevalence and factors associated with adolescent idiopathic scoliosis in Shanghai, China: an artificial intelligence-assisted screening approach. (Frontiers in public health, 2026) —
How It Works
The proposed biological pathway:
- ▸Sleep quality assessed via questionnaire
- ▸Multivariable logistic regression applied
- ▸Satisfactory sleep quality identified as protective factor
- ▸Result: lower odds of AIS among those with satisfactory sleep
Who Might Benefit
Evidence fit by population:
- ▸School students aged 9-15 years in Shanghai, China (n=5,026 from six schools in five districts)
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Cross-sectional design prevents establishing causality between sleep quality and AIS
- ▸Sleep quality was self-reported via questionnaire, which may introduce recall bias
Frequently Asked Questions
What was the prevalence of adolescent idiopathic scoliosis in this study?▼
The crude radiographically confirmed detection rate was 3.2% (162/5,026), and the IPW-adjusted estimated population prevalence was 3.8%.
How was sleep quality measured in this study?▼
Sleep quality was assessed through questionnaires completed by students, and categorized as satisfactory or unsatisfactory for analysis.
What other factors were associated with AIS in this study?▼
Female sex, improper sitting posture among girls, very low post-exercise fatigue among boys, and frequent one-sided exertion sports were associated with higher AIS risk, while higher BMI, balanced walking posture, and satisfactory sleep quality were protective.
Was the AI screening method accurate?▼
Yes, the AI-assisted structured-light screening showed high accuracy: IPW-adjusted sensitivity of 0.832, specificity of 0.995, PPV of 0.865, NPV of 0.993, and overall accuracy of 0.989.
