TI  - Methodological challenges in the application of the glycemic index in 
      epidemiological studies using data from the European Prospective Investigation 
      into Cancer and Nutrition.

AB  - Associations between the glycemic index (GI) or glycemic load (GL) and diseases 
      are heterogeneous in epidemiological studies. Differences in assigning GI values 
      to food items may contribute to this inconsistency. Our objective was to address 
      methodological issues related to the use of current GI and GL values in 
      epidemiological studies. We performed ecological comparison and correlation 
      studies by calculating dietary GI and GL from country-specific dietary 
      questionnaires (DQ) from 422,837 participants from 9 countries participating in 
      the European Prospective Investigation into Cancer and Nutrition study and single 
      standardized 24-h dietary recalls (24-HDR) obtained from a representative sample 
      (n = 33,404) using mainly Foster Powell's international table as a reference 
      source. Further, 2 inter-rater and 1 inter-method comparison were conducted, 
      comparing DQ GI values assigned by independent groups with values linked by us. 
      The ecological correlation between DQ and 24-HDR was good for GL (overall r = 
      0.76; P < 0.005) and moderate for GI (r = 0.57; P < 0.05). Mean GI/GL differences 
      between DQ and 24-HDR were significant for most centers. GL but not GI from DQ 
      was highly correlated with total carbohydrate (r = 0.98 and 0.15, respectively; P 
      < 0.0001) and this was higher for starch (r = 0.72; P < 0.0001) than for sugars 
      (r = 0.36; P < 0.0001). The inter-rater and inter-method variations were 
      considerable for GI (weighted kappa coefficients of 0.49 and 0.65 for inter-rater 
      and 0.25 for inter-method variation, respectively) but only mild for GL (weighted 
      kappa coefficients > 0.80). A more consistent methodology to attribute GI values 
      to foods and validated DQ is needed to derive meaningful GI/GL estimates for 
      nutritional epidemiology.
