Abstract
Background: Associations between ultra-processed food (UPF) consumption and clinicopathological characteristics of early-onset colorectal cancer remain incompletely understood. Objective: To examine associations between UPF energy contribution and tumor stage, anatomical subsite, and histological differentiation among younger adults with colorectal cancer. Methods: This hospital-based cross-sectional study included 84 patients aged 18–49 years at diagnosis with histologically confirmed colorectal adenocarcinoma, recruited from tertiary oncology centers in Punjab, Pakistan, between November 2025 and February 2026. A semi-quantitative food frequency questionnaire and NOVA classification estimated UPF energy contribution. Clinical characteristics were extracted from medical records. Analyses included chi-square tests, crude odds ratios, and multinomial logistic regression adjusted for body mass index, smoking, and total energy intake. Results: Mean age was 38.6 ± 6.2 years. Advanced-stage disease occurred in 78.6% of patients consuming ≥35% of energy from UPFs versus 47.6% consuming <35% (crude OR: 4.03; 95% CI: 1.55–10.47; p = 0.003). Anatomical distribution differed between groups (p = 0.021). The reported adjusted association with poorly differentiated histology was greatest for intake ≥45% versus <25% (aOR: 4.12; 95% CI: 1.84–9.22). Conclusion: Higher UPF intake was associated with advanced-stage presentation and differences in tumor characteristics within this patient population. These associations do not establish causality or cancer risk
