Circadian-Synchronized Breast Milk Feeding and Sleep in Preterm Infants: A Multicenter Randomized Controlled Trial
Effect of Circadian-Synchronized Breast Milk Feeding on Sleep in Preterm Infants: A Multicenter Randomized Controlled Trial
This clinical trial aims to find out whether a circadian-synchronized breast milk feeding approach can help improve sleep in preterm infants in the neonatal intensive care unit (NICU).
The study mainly aims to answer the following questions:
Can this feeding approach improve sleep in preterm infants? Can this feeding approach help preterm infants develop more regular sleep patterns compared with routine breast milk feeding?
Researchers will compare a feeding approach that tries to match the time when breast milk was expressed with the time when the baby is fed, with routine breast milk feeding, to see whether this method can improve sleep in preterm infants.
Participants will:
Be randomly assigned to 1 of 2 groups: circadian-synchronized breast milk feeding or routine breast milk feeding.
Receive the assigned feeding approach for at least 2 weeks during the study. Have one 12-hour continuous sleep monitoring session at 37 weeks of corrected age.
Have changes in different sleep states recorded and analyzed during the study, so that sleep patterns can be compared between the 2 groups.

Aktiver Komparator: Routine Breast Milk Feeding
Preterm infants in this group will receive routine breast milk feeding according to standard NICU practice.
Expressed breast milk will be prepared and administered without matching the time of milk expression to the time of feeding.

Experimental: Circadian-Synchronized Breast Milk Feeding
Preterm infants in this group will receive circadian-synchronized breast milk feeding in the NICU.
Expressed breast milk will be classified and labeled according to the time of milk expression into 4 time periods: morning (06:00-12:00), afternoon (12:00-18:00), evening (18:00-24:00), and late night/early morning (00:00-06:00).
During the study, breast milk collected within each predefined time period will be used preferentially for feedings scheduled within the corresponding time period.
This feeding approach is intended to keep the timing information in breast milk as consistent as possible with the infant's feeding time and will continue for at least 2 weeks during the study.

Active Sleep to Quiet Sleep Ratio (AS:QS Ratio) at 37 Weeks of Corrected Gestational Age
Zeitfenster: During a 12-hour monitoring period at 37 weeks of corrected gestational age
|
The primary outcome is the ratio of active sleep (AS) to quiet sleep (QS) across the entire monitoring period at 37 weeks of corrected gestational age.
Active sleep is one of the 2 main neonatal sleep states and is considered the precursor of rapid eye movement (REM) sleep.
Sleep data will be collected during a 12-hour monitoring period using a wearable EEG patch combined with a sleep mat.
The EEG device uses a single-channel, three-electrode configuration and supports synchronized acquisition of EEG and pulse wave signals.
All monitoring data will be preprocessed, scored, and exported using a standardized data processing workflow.
