Associations between gestational weight gain and weight development of the offspring: Differences depending on maternal pre-pregnancy BMI.

Purpose: Obesity rates are rising, and the gestational weight gain (GWG) of most women does not comply with current guidelines. This study assesses the association of pre-pregnancy BMI (ppBMI) and GWG with the child's weight development and investigates whether associations with GWG differ depending on ppBMI.

Methods: Data were obtained from the cohort study LIFE Child (Germany), comprising 691 mother-child pairs.
