Sex-stratified and ascorbic acid intake-modified associations between body roundness index and biological aging: a NHANES-based study on interactions and mediation.
Abstract
Biological aging, defined as the biological age (BA) or phenotypic age (PA) exceeding the chronological age (CA), is a key indicator of premature aging. Obesity accelerates aging; however, the effect of Body Roundness Index (BRI), an indicator of abdominal obesity, combined with sex or Ascorbic acid (Asc), on biological aging remains unclear. This study examined the association between BRI and biological aging, its interaction with sex and Asc intake, and its mediating mechanisms.

Research summary
The paper claims that Body Roundness Index (BRI) interacts with sex and ascorbic acid intake to influence biological aging. This study is relevant as it explores factors that may contribute to biological aging, which is a key aspect of longevity research.
