Assessment
Primary outcomes
The relationships among intestinal microbial patterns, autonomic nervous activity, and cognitive development in Japanese children and mothers.
Key secondary outcomes
We will examine the relationship between the following items and intestinal bacterial flora in order to identify factors that influence the variety and pattern of intestinal bacterial flora.
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)
