BACKGROUND: Few studies have evaluated nutritive effects of prebiotics on infant behavior state, physiology, or metabolic status. METHODS: In this double-blind randomized study, infants (n = 161) received cow's milk-based infant formula (Control) or similar formula with an added prebiotic blend (polydextrose and galactooligosaccharides [PDX/GOS]) from 14-35 to 112 days of age. Infant wake behavior (crying/fussing, awake/content) and 24-h sleep-wake actograms were analyzed (Baseline, Days 70 and 112). Salivary cortisol was immunoassayed (Days 70 and 112). In a subset, exploratory stool 16S ribosomal RNA-sequencing was analyzed (Baseline, Day 112). RESULTS: One hundred and thirty-one infants completed the study. Average duration of crying/fussing episodes was similar at Baseline, significantly shorter for PDX/GOS vs. Control at Day 70, and the trajectory continued at Day 112. Latency to first and second nap was significantly longer for PDX/GOS vs. Control at Day 112. Cortisol awakening response was demonstrated at Days 70 and 112. Significant stool microbiome beta-diversity and individual taxa abundance differences were observed in the PDX/GOS group. CONCLUSIONS: Results indicate faster consolidation of daytime waking state in infants receiving prebiotics and support home-based actigraphy to assess early sleep-wake patterns. A prebiotic effect on wake organization is consistent with influence on the gut-brain axis and warrants further investigation.
