Rationale and design of ePPOP-ID: a multicenter randomized controlled trial using an electronic-personalized program for obesity in pregnancy to improve delivery.

Background: Pre-pregnancy obesity and excessive gestational weight gain (GWG) are established risk factors for adverse pregnancy, delivery and birth outcomes. Pregnancy is an ideal moment for nutritional interventions in order to establish healthier lifestyle behaviors in women at high risk of obstetric and neonatal complications.

Methods: Electronic-Personalized Program for Obesity during Pregnancy to Improve Delivery (ePPOP-ID) is an open multicenter randomized controlled trial which will assess the efficacy of an e-health web-based platform offering a personalized lifestyle program to obese pregnant women in order to reduce the rate of labor procedures and delivery interventions in comparison to standard care.

Impact of gestational weight gain on perinatal outcomes after a bariatric surgery.

Background: Recommendations by the Institute of Medicine (IOM) on gestational weight gain (GWG) for women with histories of bariatric surgery have yet to be studied.

Objectives: To describe GWG in women with histories of bariatric surgery and to investigate the relationship between GWG and maternal and neonatal outcomes.

Study Design: A bicentric retrospective study on the medical charts of pregnant women with histories of bariatric surgery who delivered between 2003 and 2017 in two level III maternity units.
