Brief Summary

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

Childhood obesity is a strong predictor of adult obesity with health and economic consequences for the individual and society. Adiposity rebound (AR) is a rise in the Body Mass Index occurring between 3-7 years. Early adiposity rebound (EAR) occurs at a median age of 2 years and is a risk factor for later obesity. Events happening in "the first 1,000 days" play a role in obesity development. One of the key elements in this crucial time window is the gut microbiome, a highly dynamic organ that is sensitive to environmental exposure being linked to obesity development. Prenatal (dietary/lifestyle maternal factors and environmental exposure) and postnatal determinants (the type of feeding, sleep patterns, speed of growth) and environmental obesogenic pollutants may influence the infant microbial colonization, thus increasing the risk of EAR onset.

LIMIT will holistically identify the longitudinal interplay between the intestinal microbiome and infant/maternal nutritional and lifestyle habits, environmental factors exposure and anthropometric measurements, in children with AR vs EAR, driving new mechanistic insights to create an EAR predictive model.

The study will evaluate a group of 150 mother-infant pairs, during the first four years of life at different follow-up.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Dyads

Mother/infant pairs will be evaluated for anthropometric parameters, prenatal (dietary/lifestyle maternal factors)/postnatal determinants (type of feeding, sleep patterns, speed of growth) before discharge and after different follow-up after birth. Infant urinary and stool samples will be collected and stored. The infant adiposity rebound will be monitored.
