Nonlinear association of a body shape index and hyperlipidemia: an American population-based cross-sectional study

This study provides the first comprehensive evidence of a significant association between ABSI and hyperlipidemia. The identified threshold effect suggests that ABSI may serve as a valuable anthropometric tool for hyperlipidemia risk stratification. Future studies should validate causality and explore mechanisms underlying the observed nonlinear dynamics.This study provides the first comprehensive evidence of a significant ABSI-hyperlipidemia association.
