1. Overall project description


1.1 Summary

Early life is fundamental for brain and microbiota development. Gut microbiota influences brain function. Maternal obesity affects maturation of gut microbiota and is an important predictor of cognitive dysfunction in the offspring. Cognitive decline through life is an increasingly invalidating condition, due to population ageing and the high frequency of predisposing factors (obesity, unhealthy diets). We hypothesize that the negative effects of maternal obesity on cognitive function in the offspring are partly mediated by the microbiota and its metabolites, offering the opportunity for non-invasive risk-screening and -reduction by tailored foods and diets, since earliest life stages. We use two existing cohorts of children to identify the gut bacteria and metabolites that are related to maternal obesity and offspring’s cognitive development in early, pre-scholar and scholar age. We use preclinical models to investigate cause-effect mechanisms, and develop tailored dietary interventions to counteract the effects of maternal obesity on the gut microbiota, improving offspring’s cognition. GUTMOM involves 6 academic centres, and a private industrial collaborator providing project co-funding. The plan includes dissemination and training activities for young scientists. Data management will follow the FAIR principles, and the study will contribute to the ongoing Knowledge Platform on Diet, Intestinal Microbiomics and Health.


1.2 Highlights

We observed, both in children and in preclinical models, that maternal obesity does not affect cognition in very early life stages, e.g. during lactation. Any observed effect was delayed, and accompanied by microbiota changes, whose signs were already visible at earlier life stages. Maternal obesity and stress affected systemic metabolism. Maternal obesity did not seem related to the urinary and blood metabolome in children, whereas the latter was influenced by dietary sugars. Postnatal stress led to an increase in the HPA axis function, but this reaction is weakened by the combination with maternal obesity, possibly due to a protective effect of in-utero adaptation to (dietary induced) maternal stress. So far, our results suggest that prevention may be more effective in initial life-months, and attention should be paid to adaptive and compensatory factors.
