Insights
Machine learning enhances growth monitoring for infants small for gestational age, predicting disease outcomes. Nutritional support is crucial for their physical and neurodevelopmental catch-up growth.
Area of Science:
- Neonatal Medicine
- Biomedical Engineering
- Data Science
Background:
- Infants small for gestational age (SGA) face significant health challenges.
- Linear growth testing has limitations in accurately assessing SGA infants.
- Early identification and prediction of complications are vital for SGA infant outcomes.
Purpose of the Study:
- To explore machine learning's potential to overcome linear growth test limitations for SGA infants.
- To accurately calculate and predict disease consequences in SGA infants.
- To analyze the incidence of various morbidities in early and late SGA groups.
Main Methods:
- Utilized computer analysis for data collection and judgment on SGA infant growth.
- Classified SGA infants into early and late groups based on gestational age and birth weight.
- Collected data from infants hospitalized in the neonatal intensive care unit from January 2020 to January 2021.
Main Results:
- Machine learning offers a breakthrough for SGA infant growth assessment.
- 47.3% of SGA infants may experience suffocation.
- High incidences of neonatal asphyxia (52.1%), feeding intolerance (22.5%), and intracranial hemorrhage (14.8%) were observed in the early group.
Conclusions:
- Nutrient absorption is key to promoting catch-up growth, physical development, and neurodevelopment in SGA infants.
- Nutritional supplementation focusing on nutrient absorption is essential for SGA infant physical growth.
- SGA infants require tailored nutritional strategies to optimize development and reduce long-term complications.
Abstract:
This article proposes that machine learning can break through the technical limitations of the linear growth test for the early physique of infants smaller than gestational age and can accurately calculate and predict the consequences of the disease. For testing the linear growth of the early physique of infants smaller than gestational age, the data collection and judgment are carried out according to the computer analysis method. Experimental results show that 47.3% of infants younger than gestational age may have suffocation. The experimental subjects designed in this study are small-for-gestational-age infants who were hospitalized in the neonatal intensive care unit from January 2020 to January 2021. According to the relationship between gestational age and birth weight, the survey subjects were divided into two groups: early group and late group. Male and female small-for-gestational-age infants accounted for 68% and 32%, respectively. Among them, the proportion of early gestational age was the most, with more boys than girls, and sick singleton was more than twins. In the early group, the incidence was 52.1% for neonatal asphyxia, 22.5% for feeding intolerance, 14.8% for intracranial hemorrhage, 6.3% for scleredema, 24.7% for neonatal hyperbilirubinemia, 24.6% for hypoglycemia, 1.1% for apnea, and 3.2% for respiratory distress syndrome. Infants develop differently at different stages of corrected gestational age. The incidence of low body weight (6%) after correction for 3 months was significantly reduced compared with correction for gestational age, and the difference was statistically significant (P < 0.05). The nutrient absorption of infants younger than gestational age can promote physical catch-up growth, physical development, and neurodevelopment. Therefore, the physical growth of infants younger than gestational age requires supplementation that focuses on nutrition.
