Age, Sex, and Central Adiposity as Determinants of Autonomic Nervous System Reactivity in Adults.

ABSTRACT: Background and Objectives: The autonomic nervous system (ANS) orchestrates adaptation to stress; however, its reactivity is influenced by demographic, anthropometric, and psychosocial factors. While arterial stiffness and central adiposity are established cardiovascular risk markers, less is known about how maladaptive coping strategies, cumulative life stress, and quality of life influence short-term autonomic regulation. This study examined the age- and sex-specific associations between anthropometry, maladaptive coping, life stress, quality of life, and ANS adaptation in adults. Materials and Methods: In this cross-sectional study, 122 healthy adults aged 21-78 years underwent a standardized lay-stand-lay (LSL) protocol with pulse wave analysis. Hemodynamic outcomes includ
