Whether interaction of 25(OH)D and FSH on subclinical atherosclerosis remains unknown. We investigated the relationship between 25(OH)D and FSH levels with carotid and right subclavian intima-media wall thickness (IMT), as well as it\u2019s interaction on IMT, in climacteric women with menopausal syndrome.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A total of 227 climacteric women aged 40~59 years from January 2023 to December 2024 were included in this study. Serum was assayed for 25(OH) vitamin D (25(OH)D), sex hormones, and traditional cardiovascular risk factors. The carotid and right subclavian IMT was evaluated using a B-mode ultrasound. Logistic analysis was used to estimate odds ratio (OR) and 95% CI for high IMT associated with 25(OH)D, FSH, and traditional factors. Andersson\u2019s model was applied to evaluate the additive interaction between these factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The serum concentrations of 25(OH)D were inversely (OR: 0.945, 95 CI: 0.906-0.986) correlated with high IMT but FSH (OR: 1.021, 95 CI: 1.009-1.033) and fasting blood glucose (FBG) (OR: 2.302, 95 CI: 1.383-3.831) were positively associated with high IMT.
