Conclusions The TFI has the most robust evidence of reliability and validity and has been the most extensively examined in terms of psychometric properties .

Background Frailty is widely recognised as a distinct multifactorial clinical syndrome that implies vulnerability .
The links between frailty and adverse outcomes such as death and institutionalisation have been widely evidence d. There is currently no gold st and ard frailty assessment tool ; optimizing the assessment of frailty in older people therefore remains a research priority .
The objective of this systematic review is to identify existing multi-component frailty assessment tools that were specifically developed to assess frailty in adults aged ≥60 years old and to systematic ally and critically evaluate the reliability and validity of these tools .
Hierarchical components of physical frailty predicted incidence of dependency in a cohort of elderly women.
OBJECTIVE To identify the most important predictors of early disability  incidence and devise a simple score of physical frailty . METHODS A cohort of 545 high-functioning women aged 75 years and older was followed for 7 years . Every year , the self-reported loss of at least one instrumental activity of daily living was chosen as definition of disability . An extension of the logistic regression for repeated responses , the r and om-effect model , was used to assess the effects of baseline predictors . The regression coefficients of the final multivariate model were scaled and rounded to create a practical score . RESULTS The proportion of women reporting disability increased from 22.1 % to 52.1 % throughout the follow-up . In the multivariate model , increasing age , lower performances in mobility and balance tests , bad perceived health , lower muscle strength , higher body mass index , lower educational level , and lower reported physical activity were strong predictors of disability . Evaluating the predictive value of the simplified predictive score on an independent cohort gave a c-statistic equal to .71 . CONCLUSION The use of a powerful fitting method allows to establish a hierarchy between the components of physical frailty and to provide a predictive score with substantial practical value for clinicians and public health professionals
