Association between triglyceride-cholesterol-body weight index and sarcopenia in the older adults from China: A cross-sectional study.

ABSTRACT:

Background

The triglyceride-cholesterol-body weight index (TCBI) is a simple and reliable indicator of nutritional status. This investigation aimed to explore the association between TCBI and sarcopenia among older individuals in China.

Methods

The AWGS 2019 criteria were utilized to evaluate sarcopenia. TCBI was calculated as (TG × TC × BW)/1000. Logistic regression analysis explored the independent connection between TCBI and the occurrence of sarcopenia. RCS was employed to investigate both linear and nonlinear correlations, and threshold effects were scrutinized. Furthermore, subgroup and sensitivity analyses were also conducted.

Results

This study included 5293 participants. The TCBI was found to be negatively associated with sarcopenia in a fully corrected model
