    Assessing the Alignment of Chilean Food-Based Dietary Guidelines on Cancer Prevention: A Content Analysis
    (2025) Ortega Guzmán, Alejandra; Parra Soto, Solange; Vega Salas, María Jesus; Rodríguez Osiac, Lorena; Sandra López-Arana
    Background/Objectives: Cancer is a multifactorial disease. Evidence suggests that 30% to 50% of cancer incidence is linked to unhealthy behaviors. It is therefore important that dietary recommendations, including population-based dietary guidelines, and public policies be designed to support and facilitate healthier choices. We evaluated the alignment between the updated Chilean Food-Based Dietary Guidelines (FBDGs) and cancer prevention recommendations from the World Cancer Research Fund (WCRF/AICR) and the Latin America and the Caribbean Code Against Cancer (LAC-Code). Methods: A qualitative content analysis was performed based on the dissemination and technical documents from the updated Chilean FBDGs (2023), the WCRF/AICR and the LAC Code. A first set of codes was developed to evaluate the relevance of the messages with cancer prevention recommendations, and a second one aimed to characterize the food and diet recommendations included in cancer prevention recommendations and the Chilean FBDGs. Furthermore, we compared the 10 Chilean FBDG messages with the WCRF/AICR and the LAC Code recommendations. Results: The updated Chilean FBDG messages met most of the categories included. Four out of ten of the Chilean FBDG messages were directly aligned with LAC Code and the WCRF/AICR recommendations, five had an indirect relationship, and one was not related to any cancer recommendation. Conclusions: Our study suggests that the updated Chilean FBDG messages are most often indirectly aligned with the worldwide and the Latin American region cancer prevention recommendations over the role of diet, nutrition and physical activity in cancer risk among the general population.

    Associations of six adiposity-related markers with incidence and mortality from 24 cancers—findings from the UK Biobank prospective cohort study
    (2021) Parra Soto, Solange; Ferreccio Readi, Catterina; Cowley, Emma S.; Rezende, Leandro F. M.; Mathers, John C.; Pell, Jill P.; Ho, Frederick K.; Celis Morales, Carlos
    Abstract Background Adiposity is a strong risk factor for cancer incidence and mortality. However, most of the evidence available has focused on body mass index (BMI) as a marker of adiposity. There is limited evidence on relationships of cancer with other adiposity markers, and if these associations are linear or not. The aim of this study was to investigate the associations of six adiposity markers with incidence and mortality from 24 cancers by accounting for potential non-linear associations. Methods A total of 437,393 participants (53.8% women; mean age 56.3 years) from the UK Biobank prospective cohort study were included in this study. The median follow-up was 8.8 years (interquartile range 7.9 to 9.6) for mortality and 9.3 years (IQR 8.6 to 9.9) for cancer incidence. Adiposity-related exposures were BMI, body fat percentage, waist-hip ratio, waist-height ratio, and waist and hip circumference. Incidence and mortality of 24 cancers sites were the outcomes. Cox proportional hazard models were used with each of the exposure variables fitted separately on penalised cubic splines. Results During follow-up, 47,882 individuals developed cancer and 11,265 died due to cancer during the follow-up period. All adiposity markers had similar associations with overall cancer incidence. BMI was associated with a higher incidence of 10 cancers (stomach cardia (hazard ratio per 1 SD increment 1.35, (95% CI 1.23; 1.47)), gallbladder (1.33 (1.12; 1.58)), liver (1.27 (1.19; 1.36)), kidney (1.26 (1.20; 1.33)), pancreas (1.12 (1.06; 1.19)), bladder (1.09 (1.04; 1.14)), colorectal (1.10 (1.06; 1.13)), endometrial (1.73 (1.65; 1.82)), uterine (1.68 (1.60; 1.75)), and breast cancer (1.08 (1.05; 1.11))) and overall cancer (1.03 (1.02; 1.04)). All these associations were linear except for breast cancer in postmenopausal women. Similar results were observed when other markers of central and overall adiposity were used. For mortality, nine cancer sites were linearly associated with BMI and eight with waist circumference and body fat percentage. Conclusion Adiposity, regardless of the marker used, was associated with an increased risk in 10 cancer sites.
