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

BMC Neurology

Table 3 Distribution of modified Fried criteria among the participants

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 Fried^a OR not able.	565	190 (33.6)	134 (40.4)	56 (84.8)

All measures are given as n (%)
BMI Body mass index
^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;
Men: BMI ≤ 24.0 or missing BMI, ≤ 29.0 kg; BMI 24.1–28.0, ≤ 30.0 kg; BMI > 28, ≤ 32.0 kg
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
