iet is a health foundation to support breastfeeding and enable lactating women’s recovery. This study aimed to develop three valid diet adherence indices by a clinimetric contrast with different parameters. We hypothesize that these food pattern-based indices are reliable since each of their items is directly correlated, valid for studying maternal nutrition since they are positively associated with diet quality and milk biomarkers, and are directly related to calcium, fiber, and energy intake enabling the estimation of sensitive and specific cut-off points to diagnose inadequacies. A cross-sectional study recorded food frequency, anthropometric and dietary measures, and milk analysis to estimate correlations, sensitivity, and specificity (n=284). Three reliable indices agreed by >75% with food frequency: Macronutritional (MDI), Phytochemical (PDI), and Energetic (EDI), which correlated positively to the Fat Quality Index and Minimum Dietary Diversity for Women. MDI and EDI correlated
