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 insufficient evidence regarding TyG aging. This study aims provide deeper insights into connections We conducted cross-sectional using data from National Health Nutrition Examination Survey (NHANES), including 12,074 adults (aged 20 older) 2001–2010 2015–2018 cycles. Comprehensive BA were extracted for analysis. To explore BA, linear regressions employed, while logistic regression models used examine association accelerated Additionally, trend tests, subgroup analyses, smoothed fitted curves assess robustness findings. included participants mean 46.91 years (SD, 16.64); these, 50.25% female 49.75% male.

Across all subgroups, consistently showed correlation even presence significant interactions. There Higher levels are linked increased greater
