Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

High risk women for growth restricted fetuses will randomized in the second trimester into different strategies applied to the mothers: a stress reduction program based on mindfulness techniques or a nutrition interventional program based on Mediterranean diet.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Randomized controlled trial among women at higher risk to have a growth restricted fetus (30%) according to Royal College of Obstetrics and Gynecology (RCOG) Guidelines. These high-risk women will be randomized in order to evaluate an improvement in several outcomes thanks to different strategies applied to the mothers: a stress reduction program based on mindfulness techniques or a nutrition interventional program based on Mediterranean diet.

Main hypothesis: specific interventions improving maternal lifestyle and well being have a positive impact on pregnancy outcomes as well as on fetal growth and development.

Secondary hypothesis is that interventions to improve maternal lifestyle well being have a positive impact on offspring's outcome later in life, in terms of neurodevelopment and cardiovascular profile, mediated by epigenetic changes in offspring.
