Hypothesis

Identifying the predictors of sedentary behavior in older adults with poor mobility may affect targeted treatment strategies.

Conclusion

Older adults with poor mobility who are male, more depressed, less physically active, and have better memory are more at risk for being sedentary.

Supporting Evidence

  • The overall model was significant with R2=0.93.
  • Greater depression was a predictor of high sedentary behavior.
  • Lower moderate-to-vigorous physical activity was associated with higher sedentary behavior.
  • Male sex was linked to increased sedentary behavior.
  • Better memory was correlated with higher sedentary behavior.

Takeaway

This study found that some older adults who can't move well sit a lot more if they are sad, not active, and are men.

Methodology

Participants wore an activity monitor for 7 days and completed assessments on cognition, depression, and gait.

Participant Demographics

Participants had a mean age of 78.3 years and 44.4% were female.
