Dietary intake was assessed using 24-h dietary recalls, and UPF consumption was categorized according to the NOVA classification system. Incident atherosclerosis cases were identified through hospital admission records and death registries. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). In subset analyses, we performed nuclear magnetic resonance metabolomic profiling and plasma proteomic analysis using the Olink platform to identify molecular signatures associated with UPF-related atherosclerosis risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      During a median follow-up of 10.93\u202fyears (interquartile range, 10.83\u201311.40\u202fyears), 654 incident cases of atherosclerosis were documented. After multivariable adjustment, participants in the highest quartile (Q4) of servings\/day showed an elevated risk (HR 1.40, 95% CI 1.12\u20131.75;\n                      <jats:italic>p<\/jats:italic>\n                      \u202f=\u202f0.003) compared to the lowest quartile (Q1). Similarly, participants in Q4 of UPF consumption (g\/day) had a 29% increased risk of atherosclerosis compared to those in Q1 (HR 1.29, 95% CI 1.03\u20131.60;\n                      <jats:italic>p<\/jats:italic>\n                      \u202f=\u202f0.024). Restricted cubic spline analysis revealed higher UPF intake was associated with higher risk. Sparse LASSO identified UPF-related signatures comprising 30 metabolites and 25 proteins, predominantly involving lipoprotein, energy-metabolic, inflammatory, and endocrine pathways. Several biomarkers remained associated with incident atherosclerosis after multivariable adjustment and multiple-testing correction.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Higher UPF consumption is associated with increased atherosclerosis risk.
