Objectives

Narrative objectives1

This study aims to explore following four points. (1) create the database about intestinal bacterial flora of infants and their mothers in Japan. (2) identify factors that influence the intestinal microbial patterns. (3) examine the relationship between the intestinal bacterial flora, psychophysiological characteristics and cognitive and behavioral development.

Assessment

Primary outcomes

(1) The developmental changes of intestinal microbial patterns in Japanese infants and mothers.
(2) The Relationship between intestinal microbial patterns in infants and mothers and cognitive development in infants.

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 habits, 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)
