Summary

The overall aim of the project is to investigate how bowel habits and nutrition in early life relate to the infant gut microbiome and metabolome from birth to 1 year of age. By unravelling links between these factors in early life, we might be able to identify new putative mechanisms by which diet via microbiota-dependent pathways affects intestinal motility in early life. Furtermore, it will be explored how the development of the gut microbiome associates with the child´s development.

Detailed description

A cohort including 125 mother/infant pairs will be established with the purpose of following the infants' progression in diet, bowel habits, gut and oral microbiome, gut and oral metabolome, physiological and mental development from birth to 12 months of age. This will be possible by longitudinal collection and analysis of biological samples and data from birth until 1 year of age. The primary hypotheses to be tested are that early dietary patterns (composition, complexity, quality, and timing) and bowel habits (stool frequency, consistency, and transit time) are associated with the development of the infant gut microbial composition and metabolism. The secondary hypotheses to be tested are that the development of the infant gut microbial composition and metabolism associate with growth (body weight, length, body mass index, head circumference, body composition), development of the immune system as reflected in the gut (fecal cytokines, immunoglobulins, lipopolysaccharide, antigens) as well as the systemic circulation (blood cytokines, immune cells), host metabolism (blood metabolome, appetite hormones, urine metabolome), and physical development (sleep, motor development, mental development). The tertiary hypotheses to be tested are that the establishment and development of the infant gut microbiome is associated with external environmental factors (household, siblings, maternal diet, maternal fecal microbiome, maternal physical activity, birth conditions, and perinatal factors), and internal factors (infant oral cavity, tooth development, use of pacifier).
