The association between poor performance on SPPB and all-cause mortality remained highly consistent independent of follow-up length , subsets of participants , geographic area , and age of the population .
Conclusions An SPPB score lower than 10 is predictive of all-cause mortality .
The systematic implementation of the SPPB in clinical practice setting s may provide useful prognostic information about the risk of all-cause mortality .
Background The Short Physical Performance Battery ( SPPB ) is a well-established tool to assess lower extremity physical performance status .
Its predictive ability for all-cause mortality has been sparsely reported , but with conflicting results in different subsets of participants .
The aim of this study was to perform a meta- analysis investigating the relationship between SPPB score and all-cause mortality  .
Objectively assessed physical activity and lower limb function and prospective associations with mortality and newly diagnosed disease in UK older adults: an OPAL four-year follow-up study
Background : objective measures of physical activity and function with a diverse cohort of UK adults in their 70s and 80s were used to investigate relative risk of all-cause mortality and diagnoses of new diseases over a 4-year period . Participants : two hundred and forty older adults were r and omly recruited from 12 general practice s in urban and suburban areas of a city in the United Kingdom . Follow-up included 213 of the baseline sample . Methods : socio-demographic variables , height and weight , and self-reported diagnosed diseases were recorded at baseline . Seven-day accelerometry was used to assess total physical activity , moderate-to-vigorous activity and sedentary time . A log recorded trips from home .  Lower limb function was assessed using the Short Physical Performance Battery . Medical records were accessed on average 50 months post baseline , when new diseases and deaths were recorded . Analyses : ANOVAs were used to assess socio-demographic , physical activity and lower limb function group differences in diseases at baseline and new diseases during follow-up . Regression models were constructed to assess the prospect i ve associations between physical activity and function with mortality and new disease . Results : for every 1,000 steps walked per day , the risk of mortality was 36 % lower ( hazard ratios 0.64 , 95 % confidence interval ( CI ) 0.44–0.91 , P = 0.013 ) . Low levels of moderate-to-vigorous physical activity ( incident rate ratio ( IRR ) 1.67 , 95 % CI 1.04–2.68 , P = 0.030 ) and low frequency of trips from home ( IRR 1.41 , 95 % CI 0.98–2.05 , P = 0.045 ) were associated with diagnoses of more new diseases . Conclusion : physical activity should be supported for adults in their 70s and 80s , as it is associated with reduced risk of mortality and new disease development
