Resumen

Background: Ultra-processed food (UPF) consumption has increased significantly in Latin America and Spain, impacting both health and environmental sustainability. To our knowledge, this is the first multicenter study to examine the association between UPF consumption and sustainable lifestyle behaviors in Latin America and Spain. Objective: To evaluate the association between UPF consumption and sustainable lifestyle behaviors in Latin America and Spain. Methods: This was an observational, analytical, multicenter, cross-sectional study. A validated, self-administered online questionnaire was distributed in 14 countries between March 2023 and January 2024. The survey collected sociodemographic data, UPF intake (classified using the NOVA system), body mass index and sustainable lifestyle behaviors (food, transport, environment). Multivariate linear regression models were applied to assess associations, adjusting for age, sex, smoking, physical activity and BMI. Results: Among 6009 adults (mean age: 34.98 ± 12.55; 79.5% women), those with the highest consumption of UPF (fast food, beverages and juices, salty snacks and sweet snacks) were significantly more likely to be in the least sustainable quartile compared to those who did not consume these food products ((OR = 2.51; 95% CI: 1.79–3.54), (OR = 1.82; 95% CI: 1.50–2.22), (OR = 1.51; 95% CI: 1.32–1.73) and (OR = 1.42; 95% CI: 1.20–1.67), respectively, with p values < 0.001). Conclusions: High consumption of ultra-processed foods (UPFs) is inversely associated with sustainable lifestyles. These findings position UPF consumption not only as a health problem but also as a key indicator of unsustainable lifestyles.
