Modeling changes in health perception following hip fracture

Area of Science:

• Gerontology
• Health Psychology
• Rehabilitation Medicine

Background:

• Health perception is a crucial indicator of health-related quality of life.
• Previous studies identified various correlates of perceived health, but lacked comprehensive multivariate models.
• Understanding the interplay of physical, social, and psychological factors post-hip fracture is essential.

Purpose of the Study:

• To develop and test a multivariate model explaining health perception after hip fracture.
• To investigate the influence of physical, social, and psychological factors on post-fracture health perception.
• To explore the impact of the change in physical function on perceived health.

Main Methods:

• Interviewed 222 hip fracture patients (aged 65+) in-hospital and at 3 months post-fracture.
• Collected data on pre- and post-fracture physical function, social support, and health perception.
• Obtained comorbidities and demographic data from medical records; developed and refined a theory-based model.

Main Results:

• The final model, after minor modifications, showed a good fit with the data.
• Comorbidities and physical function were the strongest predictors of health perception.
• Improved post-fracture social support, higher socioeconomic status, and higher pre-fracture health perception also positively influenced outcomes.

Conclusions:

• Interventions targeting pre-fracture physical function and post-fracture social support may enhance health perception.
• The causal factors influencing health perception may differ between pre- and post-major health events like hip fracture.
• Future research should incorporate emotional health components to refine the predictive model.
