Participants were classified into premenopausal and postmenopausal groups according to the Stages of Reproductive Aging Workshop +10 (STRAW\u00a0+\u00a010) criteria. Menopause-related symptoms were assessed using the modified Kupperman Index (KMI). Body fat percentage (PBF) and waist-to-hip ratio (WHR) were measured using a bioelectrical impedance analyzer, and serum reproductive hormone levels, including estradiol (E\n                      <jats:sub>2<\/jats:sub>\n                      ), were determined by chemiluminescent immunoassay. Multivariable linear regression models were used to examine the association between body composition parameters and KMI scores.
