Optimising weight gain in pregnancy: key challenges and solutions for maternal obesity prevention

Abstract

Pregnancy is a high-risk period for excess gestational weight gain and subsequent obesity development. Antenatal lifestyle interventions are prioritised to optimise weight, with current evidence demonstrating efficacy and associated reduction in risk of adverse maternal and neonatal outcomes. Yet, evidence to guide the field from efficacy-based to implementation research within real-world settings is lacking, and several key challenges remain. Here, we discuss key considerations to support the implementation of accessible, relevant, effective, and low-cost lifestyle interventions in routine pregnancy care. This includes identifying what components of lifestyle interventions are most effective, with pragmatic guidance on how to conduct implementation research, improving rigour in reporting to ensure learnings from implementation are captured, and recognising and addressing the socioecological aspects of obesity prevention, including supporting women living with socioeconomic disadvantage and reducing weight stigma.
