AB  - OBJECTIVE: To evaluate the reproducibility and validity of a previously 
      constructed FFQ to assess the usual diet of patients with type 2 diabetes 
      mellitus (T2DM). DESIGN: Cross-sectional survey using two quantitative FFQ 
      (1-month interval) supported by a food photograph portfolio, a 3 d weighed diet 
      record (WDR) and urinary N output measurement (as a biomarker of protein intake). 
      SETTING: Group of Nutrition in Endocrinology, southern Brazil. SUBJECTS: 
      Out-patients with T2DM. RESULTS: From a total of 104 eligible T2DM patients, 
      eighty-eight were included in the evaluation of FFQ reproducibility and 
      seventy-two provided data for the validity study. The intakes estimated from the 
      two FFQ did not differ (P > 0.05) and the correlation coefficients were 
      significant (P < 0.01) for energy and nutrients, ranging from 0.451 (soluble 
      fibre) to 0.936 (PUFA). Regarding the validity evaluation, data from the FFQ were 
      higher than those from the WDR for total (28.3%), soluble (27.4%) and insoluble 
      fibres (29.1%), and SFA (13.5%), MUFA (11.1 %) and total lipids (9.2%; all P < 
      0.05). There were significant correlation coefficients between the FFQ and WDR 
      for most nutrients, when adjusted for energy intake and de-attenuated. Also, the 
      Bland-Altman plots between the FFQ and WDR for energy and macronutrient intakes 
      showed that the FFQ may be used as alternative method to the WDR. The validity 
      coefficient (using the method of triads) for the FFQ protein intake was 0.522 
      (95% CI 0.414, 0.597). CONCLUSIONS: This quantitative FFQ was valid and precise 
      to assess the usual diet of patients with T2DM, according to its validity and 
      reproducibility.
