Compositional development of Bifidobacterium and Lactobacillus microbiota is linked with crying and fussing in early infancy.

ABSTRACT:

Objectives

Our aim was to establish whether there is an interconnection between the compositional development of the gut microbiota and the amount of fussing and crying in early infancy.

Methods

Behavioral patterns of 89 infants during the 7(th) and 12(th) week of life were recorded in parental diaries. Total distress was defined as the sum of daily amounts of crying and fussing. Infants' gut microbiota profiles were investigated by several molecular assays during the first six months of life.

Results

The median (range) duration of total distress among the infants was 106 (0-478) minutes a day during the 7(th) and 58 (0-448) minutes a day during the 12(th) week. The proportion of Bifidobacterium counts to total bacterial counts was inversely associated with the amount
