Brief summary
This study was planned to evaluate the effect of feeding model with chronobiologic approach on circadian rhythm, growth and physiologic parameters of newborns.
Detailed description
The newborn period is a period when all babies need their basic needs to be met and all babies are very sensitive physiologically, neuro-biologically and psycho-emotionally, but the newborn period is also a very important period in the development of circadian rhythm. It is important to establish a healthy sleep pattern for the formation of the circadian rhythm and the continuation of the functions of all other systems, especially the central nervous system. Formation of circadian rhythm in newborns; It shows a better development in the first 3 months with the effect of environmental factors such as nutrition, light, mother-baby interaction. Breast milk is a nutrient for the growth and development of babies, in addition, breast milk plays an active role in the formation of the baby's circadian rhythm by transmitting information about the time of day to the babies through components such as hormones and immune elements. In cases where breastfeeding is not possible, it is thought that the delivery of expressed breast milk to the babies simultaneously with the feeding model with a chronobiological approach has important effects on the sleep-wake cycle and growth and development. In studies examining circadian rhythm in newborns in the world and in our country, the limited number of studies evaluating the relationship between circadian rhythm and breast milk draws attention and further studies are recommended. However, there is no published study evaluating the effect of simultaneous administration of breast milk to the infant in line with the feeding model with chronobiologic approach on circadian rhythm, growth and physiologic parameters of newborns.
Interventions
OTHERFeeding model group with a chronobiological approach
Breast milk will be given to the newborns in the intervention group for 3 days in line with the feeding model with a chronobiologic approach simultaneously with the provision from the mother, and the newborn will be ensured to receive breast milk in accordance with the day cycle. Within the scope of the study, firstly, mothers and nurses in the NICU will be informed about the study. Mothers will be asked to put the milk mothers express between 06:00-17:59 in the daytime breast milk storage bag and the milk mothers express between 18:00-05:59 in the nighttime breast milk storage bag and bring them to the unit. The brought breast milk will be prepared by the nurses by matching day and night milk according to the dates, with the first milk brought in priority, and the newborns will be fed by using the time of day factor (cycle so that the milk collected during the day will be given during the day and the milk expressed at night will be given at night).

Intervention model description
The study will be conducted with a total of 40 newborns (intervention group=20, control group= 20). In order to prevent selection bias in the study, participants will be randomly assigned to the intervention and control groups and the block randomization method, one of the fixed probability randomization methods, will be used in randomization. Each of the intervention and control groups will be represented by one of the letters A and B. In the creation of the 4-block (2A, 2B); the assignment of 10 blocks from the total number of options determined using the permutation method will be carried out with the random numbers table tool on the www.random.org website.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Newborn Introductory Information Form | First measurement - Before the study (before randomization) | The form prepared by the researcher in line with the literature (Galland et al., 2012; Huang et al., 2021; Caba-Flores et al., 2022) consists of questions including the obstetric characteristics of the infant such as gender, gestational-postnatal age, type of delivery, APGAR scores, birth weight, height, head circumference, and the current clinical status of the infant such as diet, comorbidity, and total number of hospitalization days. The questionnaire form was sent to 5 academicians specialized in Pediatric Nursing, their expert opinions were obtained, and the questionnaire form was finalized by making the necessary changes in line with their suggestions. Information about the newborns in the control and experimental groups was collected by the researcher through the Newborn Introductory Information Form before the study, hospital records of the newborn and the primary nurse through face-to-face interview method will be collected in about 5 minutes. |
| Newborn Growth and Physiologic Parameters Follow-up Chart | First measurement - up the end of the first day night and day measurements | Temperature (°C), Pulse Rate (min), Blood Pressure (mmHg), Respiratory Rate (min), O2 Saturation (mmHg) will be recorded for 3 days during the day-night cycle of the infants followed in both groups. Physiologic parameters will be measured 1 hour after the 2nd daytime feeding and 1 hour after the 2nd nighttime feeding (i.e. after the baby's 6th feeding). The amount of breast milk received by the infant (ml) will be monitored for three days separately in the daytime (06:00-17:59) and nighttime (18:00-05:59) cycle. In addition, the infants will be followed up in terms of Body Weight (g), Height (cm), Head circumference (cm), Persentile values until the infants are discharged from the hospital and all these parameters will be recorded through the Newborn Growth and Physiological Parameters Follow-up Chart created by the researcher. |
| Newborn Circadian Rhythm Follow-up Chart | First measurement -up the end of the first day circadian rhythm measurements | At the end of 3 days, the records of the duration of the babies' being in Wakefulness, REM, N-REM / EVRE I, N-REM / EVRE II, N-REM / EVRE III, N-REM / EVRE III, N-REM / EVRE IV measured by Bispectral Index (BIS) in 5-minute periods within a 24-hour time cycle will be taken from the BIS monitor records and entered into the Newborn Circadian Rhythm Follow-up Chart created by the researcher. |
