Objectives

Narrative objectives1

This study examines developmental changes in the relationship between gut microbiota, autonomic nervous system, and social cognitive development in infants and their caregivers (mothers) in Japan.
Specifically, we will clarify how the following associations (1), (2), and (3) change from 8 months to 18 months.
(1) Gut microbiota of mother and child
(2) Individual differences in synchrony and fluctuation patterns between mother and child based on neurophysiological data (autonomic nervous system, hormones) of mother and child during mother-infant interaction.
(3) Psychological characteristics and social cognitive development of caregivers and infants, as assessed by questionnaires and eye tracking data.

Basic objectives -Others

We will examine the possibility that physical factors (body composition and motor function) and dietary habits of caregivers are related to the physical and mental development of infants.

Assessment

Primary outcomes

This study examines developmental changes in the relationship between gut microbiota, autonomic nervous system, and social cognitive development in infants and their caregivers (mothers) in Japan.

Key secondary outcomes

We will examine the relationship between the intestinal microbiota and the following variables in order to identify factors related to the physical and mental development of infants.
1 lifestyle habit (e.g., food habit, sleep schedule, exercise habits)
2 physical characteristics (e.g., allergy, susceptibility to cold viruses)
3 psychological traits of mothers (e.g., stress, depressive tendency)
4 infant behavioral characteristics (e.g., temperament)
