Table 3 Distribution of modified Fried criteria among the participants

From: Association between in-hospital frailty and health-related quality of life after stroke: the Nor-COAST study

Component Operational definition N Total Prefrail Frail
Exhaustion Q1: ‘Did you feel constantly fatigued for more than one week before the stroke?’ 613 115 (18.7) 80 (22.2) 35 (54.7)
Low physical activity Q2: ‘Did you engage in exercise/physical activities less than once a week before your stroke?’ 617 126 (20.4) 85 (23.4) 41 (63.1)
Weight loss Q3: ‘Have you experienced unintentional weight loss of 3 kg or more in the last 6 months?’ 606 67 (11.1) 46 (12.8) 21 (32.8)
Slow gait speed A1: Gait test 4 m: ≥ 6 s OR not able. 596 217 (36.4) 157 (42.9) 60 (90.9)
Weak grip strength A2: Grip strength limits defined by Frieda OR not able. 565 190 (33.6) 134 (40.4) 56 (84.8)
  1. All measures are given as n (%)
  2. BMI Body mass index
  3. aLimits by Fried: Women: BMI ≤ 23.0 or missing BMI, ≤ 17.0 kg; BMI 23.1–26.0, ≤ 17.3 kg; BMI 26.1–29.0, ≤ 18.0 kg; BMI > 29.0, ≤ 21.0 kg;
  4. Men: BMI ≤ 24.0 or missing BMI, ≤ 29.0 kg; BMI 24.1–28.0, ≤ 30.0 kg; BMI > 28, ≤ 32.0 kg
  5. This table shows the number and proportion of prefrail/frail participants fulfilling the five criteria. N is the number of participants who completed the required test/question. Q1–3 are questions about the pre-stroke state, while A1–2 are physical assessments performed in hospital
