The causes of mortality of nutritional origin (MNO) are not classified in the consecutive reviews of the international disease classification (IDC) and there is no agreement for their most proper classification. The objective of this study is to elaborate, using the last ICD as a guide, a list of causes of mortality of nutritional origin which will be used as a reference in future studies. A two round Delphi method was organized with an expert's consenssus in clinical nutrition. The experts were asked to classify a list of causes of MNO in 4 groups; 1) group A: congenital errors related to nutrition, 2) group B: Causes associated with other pathologies, 3) group 3: Excess and defect nutrition disorders, and 4) excluded. In total, 86 causes of MNO were taken under the consensus of experts, and 79 (91.9%) came to an agreement. 14 (17.7%) causes were classified in group A, 5 (6.3%) causes in group B, 37 (46.8%) causes in group C and 23 (29.1%) were excluded. This is a first approach to the classification of mortality causes of nutritional origin, probably due to the ambiguity and disparity of opinions between experts with respect to these causes. This new classification will be very useful due to the fact that it will enable homogenization of the studies and that way we will have comparable studies, using it as a clarifier annex for the ICD of the moment.
