Global prevalence of sarcopenia varies widely based on diagnostic criteria
In short: A systematic review and meta-analysis of 151 studies found that the global prevalence of sarcopenia ranges from 10% to 27%. Researchers noted that these figures fluctuate significantly depending on the specific diagnostic classifications and cut-off points used to define the condition.
The researchers analyzed data from 151 studies involving hundreds of thousands of participants to estimate how common muscle loss is worldwide. They found that prevalence rates differ by region, age, and sex.
Because no single diagnostic standard for sarcopenia has been established, results vary significantly between studies, making global comparisons difficult.
Why it matters: The wide variation in prevalence rates stems from the absence of a universal diagnostic standard for sarcopenia.
