Design outcomes

Primary

Measure	Time frame
(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.	—

Secondary

Measure	Time frame
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)	—
