Objective:To identify factors potentially associated with weight retention measured 9 months after childbirth.Design:Prospective study with four follow-up waves in time (0.5, 2, 6 and 9 months postpartum).Setting:Rio de Janeiro, Brazil.Subjects and methods:Two hundred and sixty-six Brazilian women of childbearing age. Analysis was based on hierarchical logistic regression. The dependent variable was weight retention and was defined as the difference between weight at 9 months postpartum and pre-pregnancy weight, with a dichotomised cut-off at 7.5 kg. Covariates included demographic and socio-economic data, obstetric history, anthropometric data, and data on the infant. These data were grouped in blocks and ordered according to their influence on the dependent variable.Results:Of the women studied, 19.2% presented weight retention values ≥7.5 kg. According to the logistic regression analysis, the following variables remained associated with weight retention ≥7.5 kg: total family income, difficulty or inability to read a letter, age category ≥30 years, age at first childbirth
