Comment on “global prevalence of sarcopenic obesity in older adults: A systematic review and meta-analysis"

With great interest, we read the recent meta-analysis conducted by Gao et al. [ [1] Gao Q. Mei F. Shang Y. Hu K Chen F Zhao L et al. Global prevalence of sarcopenic obesity in older adults: a systematic review and meta-analysis. Clin Nutr. 2021; 40: 4633-4641 Abstract Full Text Full Text PDF PubMed Scopus (11) Google Scholar ] who summarized the global prevalence of sarcopenic obesity with the pooled prevalence of SO being 11% (95%CI:10%–13%). The authors found that the prevalence of SO was higher when using muscle mass alone to define sarcopenia than that using muscle mass plus handgrip strength and/or functional ability. This study had multiple implications for the first study to comprehensively summarize the prevalence of SO global, which can give evidence for government and clinicians around the world to early implement preventive strategies. In addition, Gao and his colleagues used an excellent statistical analysis with broad subgroup, meta-regression, publication bias and sensitivity analysis, which make the results reliable and credible. Whereas, this article can be improved if some issues would be addressed.
