The study design—a prospective cohort study—is appropriate for investigating dietary influences on newborn nutritional outcomes. Methods, such as the use of PCF analysis, generalized structural equation modeling, and assessment tools for dietary practices, are adequately described. However, critical definitions (e.g., "inadequate dietary practices," "stunting," "wasting") could be more clearly defined. Epidemiological methods are specified, but brief explanations of the criteria for inclusion in path analysis or the goodness-of-fit assessment would enhance clarity.
