A REVIEW OF METHODS FOR CREATING PERCENTILE GROWTH RATE CHARTS OF FUNDAL HEIGHT DURING PREGNANCY. REVIEW
Introduction: Pregnancy management using centile growth charts of the standing height of the uterus during pregnancy (gravidogram), reveals a group of women with potential fetal growth disorders. The sensitivity and diagnostic value of the method depends on the methods by which the graph was created. In methods, it is important to consider variables that affect the graph, statistical methods of processing.
The purpose of the study: the study of methods for developingchartsoffundalheight (FH).
Methods: a review of the publications in the Google Scolar, PubMed, Scopus, Cochrane Library, Trip Database, Springer Link and the Reproductive Health Library was conducted. The search was not limited to a temporary, linguistic framework or type of publication. The population at which the study was conducted, the sample size, and the statistical methods of data processing were assessed.
Results: On the key words we found 242 articles. 15 studies were included in the final analysis.
Discussion: Methods of data collection, methods for calculating the gestational age, methods of statistical processing and plotting the curvesare different in these studies, which makes it impossible to qualitatively evaluate the results. In 2006, WHO experts published a report with practical recommendations for the creation of percentile schedules for children. The described methods are recommended for the use in the creation of percentile curves in all fields of medicine.
Conclusions: The increase in the quality of the percentile growth curves of FH during pregnancy depends on the methodology of the study, the quality of the data set, and the statistical method of calculating the curves. When creating charts, it is necessary to adhere to standardized methods of statistical analysis, namely methods recommended by WHO.
