Abstract The aim of this article is to apply the marginal model in the analysis of panel data on the nutritional status of newborns. After a brief review of the central aspects of marginal models, the generalized estimating equations (GEE) method, an appropriate method for estimating this type of model, is briefly reviewed. Based on a logistic marginal model with exchangeable correlation pattern, it is concluded that smoking during pregnancy and inadequate prenatal care significantly increase the probability of a low birth weight
