Maternal Lifestyle Interventions: Targeting Preconception Health.

About one-third of women of reproductive age are obese, predisposing both mother and baby to unfavourable pregnancy outcomes and initiating an intergenerational cycle of chronic metabolic disorders. Here we summarise recent research on the influence of maternal metabolic health on offspring susceptibility to future cardiometabolic diseases. Current primary lifestyle approaches (i.e., diet and exercise interventions) to halt the succession of inherited and epigenetic metabolic abnormalities have met with limited success due to late implementation, poor adherence, and/or generic guidelines. In our opinion, such interventions must commence prior to conception to improve both maternal and child health outcomes, with new approaches urgently needed to increase adherence to primary lifestyle changes among reproductive-age women.
