Head and neck cancer (HNC) is characterized by malnutrition that may persist post‐treatment and lead to dietary changes due to a desire to improve health and decrease morbidity. No longitudinal studies have examined such changes. We characterized dietary pattern change in the year after HNC diagnosis in 128 newly diagnosed HNC patients enrolled in UM Head and Neck SPORE and determined correlations with patient and tumor characteristics. Principal components analysis of 42 FFQ‐derived food groups defined 3 patterns: Whole foods; High meat/saturated fat; Convenience foods. Scores for each pattern were categorized into 4 groups that defined a score trajectory from baseline to 1‐year: Low‐Low; Low‐High; High‐High; High‐Low. Chi‐squared tests and ANOVA were used to examine associations of changes in the 3 pattern scores with demographic, clinical and behavioral variables. Most participants’ pattern scores remained stable across time points (73, 72, and 57% for Whole foods, High meat, and Convenience foods, respectively). Whole foods pattern trajectory differed significantly by education ( P = 0.04); High meat trajectory differed significantly by BMI and smoking ( P = 0.02 and 0.01, respectively); and Convenience foods trajectory differed significantly by BMI, education and sex ( P = 0.02, 0.02, and 0.05, respectively). Future studies should examine how dietary pattern changes are associated with HNC prognosis.
