Summary

Back extensor strength shows promise as a frailty marker. Stronger back muscles correlate with better physical function, suggesting it can help identify frailty in older adults.

Area of Science:

  • Gerontology
  • Musculoskeletal Health
  • Biomedical Engineering

Background:

  • Frailty is a significant geriatric syndrome associated with adverse health outcomes.
  • Current frailty assessments can be time-consuming and require specialized equipment.
  • Identifying accessible and reliable frailty markers is crucial for early intervention.

Purpose of the Study:

  • To investigate back extensor strength as a potential alternative marker for frailty.
  • To examine the association between back extensor strength and body composition.
  • To evaluate the predictive capability of back extensor strength for frailty status.

Main Methods:

  • Cross-sectional study of 560 farmers.
  • Computed tomography (CT) scans for trunk muscle and fat composition analysis.
  • Measurement of back extensor strength and Fried's frailty criteria.
  • Statistical analyses including multivariate regression, propensity score matching, and XGBoost.

Main Results:

  • Back extensor strength positively correlated with abdominal and back muscle volume (p < 0.05).
  • Lower back extensor strength was associated with reduced grip strength, walking speed, and increased exhaustion.
  • Multivariate logistic regression and XGBoost identified back extensor strength as a significant predictor of frailty.

Conclusions:

  • Back extensor strength demonstrates potential as a practical and alternative marker for assessing frailty.
  • This finding may facilitate simpler and more widespread frailty screening in clinical and research settings.
