Latch On: A protocol for a multi-centre, randomised controlled trial of perinatal support to improve breastfeeding outcomes in women with a raised BMI.

Introduction: Breastfeeding is associated with improved maternal and child outcomes. Women with a higher body mass index (BMI), who comprise about 50% of the population, are at increased risk of poorer breastfeeding practices and are a population who would benefit from breastfeeding.

Methods: This protocol is for a multi-centre, randomised controlled trial of perinatal breastfeeding support among primiparous women with a BMI >25 kg/m, using a previously-tested, multi-component intervention.
