Objective The aim of this study was to investigate the association between nutrient-based dietary patterns and squamous cell cancers of the head and neck. Methods We used a case-control study which included 548 cases and 548 controls. From these participants, we derived 23 nutrients and they were then submitted to a factorability analysis in order to conduct a principal component factor analysis. Results We were able to identify four nutrient-derived patterns. The first pattern (meat-based pattern) was positively associated with squamous cell cancer of the head and neck (OR 2.85, 95 % CI 1.81-4.15), whereas the third pattern (fruit-based) was strongly protective (OR 0.43, 95 % CI 0.27-0.63). The other nutrient patterns were also significantly associated with head and neck squamous cell carcinoma with minor ORs. Conclusion Both patterns suggest that red meat and fruits are major factors in the etiology of head and neck squamous cell cancer, replicating previous studies in the field. © Springer Science+Business Media Dordrecht 2013.
