Table 1 Comparing our model for estimating frailty with the previous common and accepted model by Morley et al.

From: Estimated frailty prevalence among Israeli elderly – results from a cross sectional national survey

  Morley 5 frail scale model [17] Our frailty model
Component number Criterion Definition Criterion used instead1 Definition
1 Aerobic Cannot walk 1 block Physical inactivity Non- engagement of any intentional physical activity in the past year
2 Illnesses >  5 diagnosed illnesses Co-morbidity ≥ 4 diagnosed morbidities 2
3 Loss of weight >  5% of the original weight in the past 6 months Spontaneous weight loss >  3 kg of the original weight in the past 1 year
4 Resistance Question: “Cannot walk up 1 flight of stairs?” Estimation of sarcopenia1 Low appendicular mass using mid arm and calf circumferences3
5 Fatigue Question: “Are you fatigued?” Low subjective health perception1 Self-assessment of personal health as same or worse compared to the previous year
  Defining robust No positive scores Defining robust No positive scores
Defining pre-frail 1–2 positive scores Defining pre-frail 1–2 positive scores
Defining frail 3 or greater positive scores Defining frail 3 or greater positive scores
  1. 1- There were no appropriate criteria obtained in MABAT survey to replace the resistance and the fatigue criteria suggested by Morley. Therefore, we used previously suggested variables that can define frailty, and which were also assessed in the survey
  2. 2- We defined comorbidities as: ≥ 4 diagnosed morbidities of the following: chronic renal failure, cardiac insufficiency, heart attack, stroke, Parkinson, asthma, hypertension, diabetes, osteoporosis and vision damage [cataract and/or glaucoma]
  3. 3- Sarcopenia was estimated in the post-hoc analysis of MABAT survey using mid arm and calf circumferences (as proxy for appendicular mass). Cut-offs of older adults’ national survey were imputed and adjusted by age group. For males: a) aged 65–74: mid upper arm and calf circumferences < 29.9 cm and 26.6 cm, respectively; b) aged 75–84: mid upper arm and calf circumferences < 28.1 cm and 34.9 cm, respectively; c) aged ≥85: mid upper arm and calf circumferences < 27.7 cm and 33.7 cm, respectively. For females: a) aged 65–74: mid upper arm and calf circumferences < 31.8 cm and 37.7 cm, respectively; b) aged 75–84: mid upper arm and calf circumferences < 30.1 cm and 35.3 cm, respectively; c) aged ≥85: mid upper arm and calf circumferences < 26.9 cm and 34.6 cm, respectively [45]
