Self‐Reported Physical Function As a Predictor of Hospitalization in the Lifestyle Interventions and Independence for Elders Study

Abstract

Background Hospitalization reduces mobility for many older adults, which in turn is associated with an increased risk of hospitalization. Physical function screening may identify an at-risk population for intervention. The Mobility Assessment Tool – short form (MAT-sf) is a brief, animated, computer-based means of assessing mobility that predicts mobility disability. This study explored whether baseline MAT-sf scores are associated with number of hospitalizations and time to first hospitalization across a median follow-up of 2.7 years. Design Post-hoc analysis of prospectively-gathered data from the Lifestyle Interventions and Independence for Elders (LIFE) Study, a randomized clinical trial of lifestyle interventions to preserve mobility in older adults, conducted in eight U.S. academic medical centers. Participants Among 1635 sedentary community-dwelling older adults enrolled in LIFE, 1574 completed baseline physical function screening including the MAT-sf, with baseline scores ranging from 30.2 (low function) to 69.8 (high function) on a scale from 30-80. Measurements Number of hospitalizations and time to first hospitalization, adjusted for age, gender, race, living alone, clinical site, baseline comorbidities, # prescription medications, and cognition. Results Of the 1557 participants with data regarding hospitalization status, 726 (47%) experienced at least one hospitalization; the majority (78%) of these experienced 1-2 hospitalizations. For every 10-point difference in MAT-sf score, the rate of all hospitalizations was higher by 19% in those with lower scores (adjusted rate ratio 1.20, 95% CI: 1.08-1.32, p<0.001). Lower baseline MAT-sf scores were also associated with an increased risk of first hospitalization (adjusted Hazard Ratio 1.20, 95% CI: 1.09 to 1.32, p< 0.01, per 10-point difference in MAT-sf). Conclusion Low MAT-sf scores identify older adults at increased risk for hospitalizations; further study is needed to test interventions to reduce hospitalizations in these patients.

Effect of a physical activity and behaviour maintenance programme on functional mobility decline in older adults: the REACT (Retirement in Action) randomised controlled trial

“…In older people, there is strong evidence of a positive effect from regular physical activity on lower limb physical functioning, 7 , 8 the ability to live independently in the community, reduced hospital admissions, and mortality. 9 , 10 Despite these substantial benefits, people become less physically active and more sedentary as they age, with only 12% of UK adults aged 65 years and older meeting UK physical activity guidelines. 11 Sedentary behaviours are even more prevalent in socioeconomically deprived parts of the population, 12 which is a key driver of health inequalities.…”

Effects of a Motor Imagery Task on Functional Brain Network Community Structure in Older Adults: Data from the Brain Networks and Mobility Function (B-NET) Study

“…In the present study, we investigated the effect of a MI task on the overall brain network using graph theory network analyses. The MI tasks employed items from the MAT-sf, a motor imagery task where performance is associated with major objective tests of mobility and predicts clinical outcomes, including major mobility disability [ 21 , 22 , 23 , 24 ]. We found that, when compared to the resting state, global community structure consistency declined during the MI tasks and with increased difficulty.…”

“…The MAT-sf is a brief, self-report tool with 10 animated video clips illustrating common mobility tasks [ 21 , 22 , 23 ]. It is correlated with major objective tests of physical function and has been found to predict outcomes following surgery and major mobility disability [ 16 , 22 , 23 , 24 ]. In the present study, we utilize a variation of the MAT-sf adapted for use in the scanner in which two videos are shown to participants that include relatively easy and more difficult motor tasks, respectively.…”

The Role of Parental Parenting in the Formation of the Child’s Self-Concept

“…Every individual has a desire to move forward, but some people have obstacles to that desire to move forward. A person tends to feel that the expectations possessed are difficult to realize, overthinking the difficulty and overthinking people's views (Callahan, 2018). Negative thinking will be very detrimental.…”
