Assessment of the components of sarcopenia and quality of life perceived of individuals on hemodialysis.
Bianca Raquel Bianchi Celoto, Flávia Andréia Marin, Maria Claudia Bernardes Spexoto
PMID 38055474WHAT IT FOUND
Sarcopenia was not associated with quality of life in 83 hemodialysis patients.
Handgrip strength and walking speed were linked to physical quality-of-life scores, weakly or moderately.
Key findings
01Sarcopenia was not associated with global quality of life or any quality-of-life domain.
02Confirmed or severe sarcopenia was 32.6% by calf circumference and 18.1% by the appendicular skeletal muscle index.
03Physical health quality of life scored lowest at 61.1 points on a 0 to 100 scale, and handgrip strength and walking speed were linked to it.

What it does not show
Single centre, non-probability sampling, so the sample may not represent other hemodialysis populations. Cross-sectional design cannot show whether sarcopenia causes poorer quality of life or whether quality of life and function change over time. Muscle mass was estimated by calf circumference and a predictive equation, not by the more robust methods recommended by the European consensus. Quality of life was measured with a generic WHOQOL-bref instrument, not a kidney-specific tool, so it may not capture concerns specific to kidney disease. Bedridden patients and people unable to perform handgrip or gait-speed tests were excluded, and 53.0% had excellent functional capacity, so results may not apply to more impaired dialysis patients.
The easy way to misread this
Do not conclude that treating sarcopenia improves quality of life. The study was cross-sectional, found no association between sarcopenia and quality of life, and only reported weak or moderate links between handgrip strength or walking speed and physical quality-of-life scores.
