Rationale: Limited evidence exists regarding the longitudinal association between ultra-processed food (UPF) consumption and novel anthropometric indices representing adiposity. This prospective cohort study aimed to determine the relationship between UPF intake and these indices in adults.

Methods: The study included 2,734 adults from the Tehran Lipid and Glucose Study (TLGS). Novel anthropometric indices—specifically the body roundness index (BRI), a body shape index (ABSI), visceral adiposity index (VAI), and adiposity estimator index (AEI)—were assessed longitudinally at baseline and every three years for a median follow-up of 12 years. UPF consumption was estimated using the NOVA food classification system. We used linear regression to estimate the association between UPF and changes in anthropometric indices.

Results: The mean age of participants was 39.8 years, and 54.1% were women. The results of linear regression indicated that three servings per day of UPF were positively associated with an annual 0.04% increase in body weight (95% CI: 0.03, 0.20), 0.05% in BMI (95% CI: 0.04, 0.22), and 0.05% in AEI (95% CI: 0.03, 0.12). No association between ultra-processed foods and annual changes in BRI (β = 0.03, 95% CI: -0.003, 0.04), ABSI (β = 0.001, 95% CI: -0.12, 0.12), WC (β = 0.03, 95% CI: -0.007, 0.16), and VAI (β = -0.006, 95% CI: -0.01, 0.009) was detected. 

Conclusion: Our results demonstrate a positive association between ultra-processed food and the progressive changes in weight, BMI, and percent of adiposity over time.
