Descriptive Information
Brief Title Infant Sleep Behaviour and Gut Microbacteria
Official Title Sleep Behaviour and Gut Microbiota in Healthy Infants
Brief Summary The overarching study aim is to evaluate the development of sleep behavior and gut microbiota (GMB), and their potential interaction, during the vulnerable period of the first year of life. Age-specific fecal profiles with bacterial genome sequencing will provide new insight into the functional coevolution of the GMB and host sleep behavior.
