Table 1 Criteria used to define physical frailty in LASI, 2017–18
From: Wealth disparity and frailty among community-dwelling older adults in India
Exhaustion | During the past week, how often did you feel: (a) tired or low in energy; (b) that everything you did was an effort. Less than three days = 0; More than three days =1. | |
Grip strength | Average grip strength score in dominant hand (2 trials) using Smedley’s handheld dynamometer (adjusted for gender and body mass index (BMI)) | |
BMI | Cut-off for Grip strength | |
For men | ||
BMI ≤ 24 | ≤ 29 kg | |
BMI 24.1–26 | ≤ 30 kg | |
BMI 26.1–28 | ≤ 30 kg | |
BMI > 28 | ≤ 32 kg | |
For women | ||
BMI ≤ 23 | ≤ 17 kg | |
BMI 23.1–26 | ≤ 17.3 kg | |
BMI 26.1–29 | ≤ 18 kg | |
BMI > 29 | ≤ 21 kg | |
Walk time | In the LASI, respondents were asked to walk 4 m twice. The time taken to walk was recorded in seconds each time, and the average time taken in both trials was calculated. (Stratified by gender and height (gender-specific cut-off a medium height) | |
Cut-off for Time to Walk 4-m | ||
Men | ||
Height ≤ 173 cm | ≥ 7 seconds | |
Height > 173 cm | ≥ 6 seconds | |
Women | ||
Height ≤ 159 cm | ≥ 7 seconds | |
Height > 159 cm | ≥ 6 seconds | |
Weight loss | Do you think that you have lost weight in the last 12 months because there was not enough food at your household?” Yes = 1, No = 0. | |
Physical activity | How often do you take part in sports or vigorous activities, such as running or jogging, swimming, going to a health center or gym, cycling, or digging with a spade or shovel, heavy lifting, chopping, farm work, fast bicycling, cycling with loads? One to three times a month or hardly ever or never = 1, once a week or more than once a week = 0 | |
Total score | 5 Items: 0–2 deficits = non-frail, 3+ deficits = frail Allowed missing 1–2 items, missing imputed with 0 (sum of available items) | |
