Article Abstract
Background: The association between sarcopenia and cardiometabolic index (CMI) among the Chinese elderly adults remains unclear. The present study aimed to examine the association based on a national survey.
Methods: Data from China Health and Retirement Longitudinal Study (CHARLS, wave 2011 and 2015) were employed. All subjects met the inclusion criteria were classified by the median of CMI. Four logistic regression models were established to explore the cross-sectional and longitudinal associations between CMI and sarcopenia. Subgroups analysis, tendency analysis, etc. were conducted to testify the robustness of the association. The non-linear relationship was explored using restricted cubic spline (RCS).
Results: 5,016 participants were enrolled in this study. The ORs of the longitudinal analysis in the models were 0.42(0.34,0.53), 0.37(0.29,0.46), 0.40(0.31,0.51) and 0.42(0.33,0.53)), respectively. Similar results were also found after propensity score matching (PSM), inverse probability weighting (IPTW) and cross-sectional analysis. Moreover, a non-linear relationship was found between CMI and sarcopenia in the total participants (both p for overall and p for non-linear < 0.001).
Conclusion: A U-shaped relationship between CMI and sarcopenia risk was found in the middle aged and elderly Chinese, with both deficient and excessive CMI levels showing detrimental effects. Maintaining a moderate CMI significantly diminishes the risk of sarcopenia.

Background: The cardiometabolic index (CMI) is a reliable marker used to assess the degree of obesity and lipid metabolism disorders in individuals. Emerging evidence indicates that disorders of lipid metabolism and sarcopenia share a common pathophysiologic basis. However, few studies have investigated the association between CMI and sarcopenia.

Although evidence suggests that lipid accumulation product (LAP) and cardiometabolic index (CMI) may be associated with the pathogenesis of sarcopenia, their relationship remains unclear. This study aims to investigate their association with sarcopenia. This cross-sectional study analyzed data from 4,172 adults aged 20-59 years from the NHANES 2011-2018 cycles.

Aims: This study aimed to explore the relationships between lipid metabolism indices-the Lipid Accumulation Product (LAP), Visceral Adiposity Index (VAI), Cardiac Metabolic Index (CMI), and Atherogenic Index of Plasma (AIP)-and sarcopenia in individuals aged ≥ 60 years, and to investigate the mediating role of uric acid (UA) in these relationships. The goal was to provide scientific evidence and practical guidance for preventing and treating sarcopenia in older adults.
Methods: Data from 2001 participants aged ≥ 60 years in the 2003-2006 National Health and Nutrition Examination Survey (NHANES) were analyzed.

Background: The cardiometabolic index (CMI), initially devised as a diagnostic tool for diabetes mellitus, has evolved into a composite biomarker for evaluating metabolic syndrome and cardiovascular disease risk. In order to shed light on any possible interactions between sarcopenia and CMI, this study will look at the relationship between the two.
Methods And Results: Data from the 2011-2018 National Health and Nutrition Examination Survey (NHANES) were analyzed to investigate the possible link between sarcopenia and CMI.
