Popis: Background Epidemiologic evidence for the association between types of fatty acid and risk of type 2 diabetes is inconsistent This may in part be due to the limitations of fatty acid measurement methods Objective The objective was to use 3 different measures of fatty acid to estimate the prospective association between fatty acid composition and development of incident diabetes Design We analyzed 199 cases of clinically incident diabetes and 184 noncases aged 40-79 y at baseline in the EPIC (European Prospective Investigation into Cancer and Nutrition)-Norfolk study Fatty acids were derived from a food frequency questionnaire (FFQ) and measured in plasma phospholipid (P FA) and erythrocyte membrane phospholipid (Ery FA) fractions by gas chromatography Results There were stronger associations with diabetes risk with the use of objectively measured tatty acids (P FA and Ery-FA) than with the FFQ in analyses adjusted for age sex and potential confounders Positive associations with diabetes were greater in magnitude with the use of P FA than with Ery FA (highest lowest tertiles) for example the palmitic acid odds ratios (ORs) were 247 (95% CI 1 37 4 46) and 1 96 (95% CI 1 10 3 49) respectively Inverse associations with diabetes were also stronger with the use of P FA than with Ery FA for example the OR for linoleic acid was 050 (95% CI 028 0 91) compared with 0 77 (95% CI 043 1 37) respectively Conclusions The objective measurement of fatty acids with the use of either P-FA or Ery-FA identifies important associations with diabetes Incidence that may be missed when assessed by FFQ Fatty acids measured in P-FA appear to be more strongly associated with diabetes incidence These findings endorse the use of objective measurement of fatty acids for nutritional-epidemiologic studies and the apparently stronger findings for the plasma fraction should be confirmed in larger studies and in different populations Am J Clin Nutr 2010 92 1214-22
