Lower sleep quality predicts one-year low back pain incidence in healthy adults

A supervised machine learning model identified lower sleep quality as one of the most important predictors of one-year low back pain incidence among 156 healthy participants. The model achieved an accuracy of 0.815 and an ROC AUC of 0.839 for out-of-sample predictions.

Bangerter C, Faude O, Dörig M, Meier ML, Hasler CC, Schmid S · Scientific reports (2026)

Participants: N/A
Duration: 1 year
Intervention: Observational assessment of baseline sleep quality, pain-related fear, demographics, health, lifestyle, lumbar spine ROM, and lifting biomechanics
Outcome: One-year low back pain incidence assessed via biweekly follow-up questionnaires
Effect Size: N/A
Population: 156 healthy participants without low back pain at baseline

Mechanism Graph

Lower sleep quality may impair tissue recovery and pain regulation
↓
Reduced sleep quality could increase pain sensitivity and fear-avoidance behaviors
↓
These factors contribute to altered lifting biomechanics and reduced lumbar spine motion
↓
Result: Increased risk of developing low back pain over one year

Limitations

  • ⚠Observational design cannot establish causality between sleep quality and LBP incidence
  • ⚠Sample size of 156 is relatively small for machine learning models, potentially limiting generalizability

Frequently Asked Questions

How was sleep quality measured in this study?▼

Sleep quality was assessed at baseline using a self-report questionnaire, though the specific instrument is not detailed in the abstract.

What other factors predicted low back pain besides sleep quality?▼

Higher BMI, greater lifting-specific pain-related fear, and reduced lumbar spine range of motion were also among the most important predictors.

Can improving sleep quality reduce the risk of low back pain?▼

This study only shows an association, not causation. Further interventional research is needed to determine if improving sleep quality lowers LBP risk.

What machine learning model was used?▼

The researchers used an Explainable Boosting Machine (EBM) to predict one-year LBP incidence from baseline variables.
