Fundamental understanding and development of preconception care strategies to improve maternal fertility and to protect offspring's health in obese individuals

Obesity is becoming a global threat, reducing mother's health and reproductive capacities and affecting the offspring's health. Clear preconception care guidelines for obese future mothers are lacking. Clinical studies are flawed and fundamental studies in basic animal models are scarce. The importance of preconception weight loss on reproduction and baby's health is heavily debated and has never been investigated in detail. This project aims to uncover the role and the importance of clinically relevant preconception care advices to obese women planning for pregnancy. To do so, we propose strategically designed fundamental obese mouse models to assess the impact of preconception weight loss, diet normalization, increased physical activity, omega-3 rich diet or the combination thereof. We will focus on four distinct major research challenges: 1) can we find improvements of mother's metabolic profile before conception in relation to the observed weight loss; 2) does the mother's own fertility success increase; 3) can we improve the postnatal health of the offspring and 4) can we safeguard the offspring's reproductive physiology. Physiological and in depth molecular outcome parameters will be combined to generate a clear and integrated view on the effects of preconception care lifestyle interventions. If successful, these novel insights will be the basis for developing future awareness and education programs aiming at improved human maternal health at the time of conception.
