Association between triglyceride glucose index and biological aging in U.S. adults: National Health and Nutrition Examination Survey.

ABSTRACT:

Background

Insulin resistance (IR) has been reported to be associated with aging; however, few studies have investigated the relationship between IR and biological age (BA). The Triglyceride-glucose (TyG) index is a recognized marker of IR. Currently, there is insufficient evidence regarding the relationship between the TyG index and biological aging. This study aims to provide deeper insights into the connections between the TyG index and biological aging.

Methods

We conducted a cross-sectional study using data from the National Health and Nutrition Examination Survey (NHANES), including 12,074 adults (aged 20 and older) from the 2001-2010 and 2015-2018 cycles. Comprehensive TyG and BA data were extracted for analysis. To explore the relationship between the TyG index and B
