Systemic inflammation index mediated the associations between dietary intake for gut microbiota and muscle mass: a cross-sectional study.

ABSTRACT:

Objective

The associations between a diet that associated with maintaining a healthy gut microbiota and muscle mass, as well as the role of inflammation in these associations, remain unclear. This study aimed to examine the associations between the dietary index for gut microbiota (DI-GM) and muscle mass, and to explore whether the systemic inflammation index (SII) mediates these associations.

Methods

A total of 6,908 participants, aged 20 to 59 years, from the 2010-2018 cycles of the National Health and Nutrition Examination Survey, were included in this cross-sectional study. The DI-GM was calculated based on the dietary intake of 13 foods or nutrients, with a higher score indicating a diet associated with a healthier gut microbiota. Muscle mass was assessed using the skel
