Summary
This study introduces a new method for analyzing preterm infant birth weights, simplifying data collection for calculating growth percentiles. The analysis revealed normal weight distributions in most cases, supporting the methodology
Area of Science:
- Neonatalogy
- Perinatal Medicine
- Biostatistics
Background:
- Preterm infant birth weight analysis is crucial for neonatal care.
- Efficient data collection methods are needed for accurate percentile calculations.
- Existing methodologies may require refinement for comprehensive preterm infant data.
Purpose of the Study:
- To develop and evaluate a novel methodology for analyzing preterm infant birth weight.
- To simplify the data collection process for creating accurate growth percentiles.
- To assess the distribution of birth weights in preterm infants.
Main Methods:
- Analysis of birth weights for 2,482 preterm infants (24-36 weeks gestation).
- Exclusion of infants with congenital defects, sepsis, or growth issues initially.
- Application of statistical tests (Box and Whisker, Kolmogorov-Smirnov, Shapiro) to identify and exclude extreme weights.
- Evaluation of weight distribution normality using kurtosis and asymmetry.
Main Results:
- The majority of preterm infant birth weight distributions were found to be normal.
- The new methodology facilitated simpler data collection for percentile calculation.
Conclusions:
- The proposed methodology offers a more efficient approach to collecting data for preterm infant percentile calculation.
- Further validation through clinical characteristic studies of small for gestational age (SGA) and large for gestational age (LGA) infants is recommended.
