Fetal Biometric Charts and Reference Equations for Pregnant Women Living in Port Said and Ismailia Governorates in Egypt

Abstract

AIM:To construct new fetal biometric charts and equations for some fetal biometric parameters for women between 12th and 41st weeks living in Ismailia and Port Said Governorates in Egypt.MATERIAL AND METHODS:This cross-sectional study was carried out on 656 Egyptian women (from Ismailia and Port Said governorates) with an uncomplicated pregnancy, and all were sure of their dates. The selected group was between the 12th and 41st weeks of gestation, recruited from the district general hospital in Ismailia and Port Said to measure ultrasonographically biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL), then for each measurement separate regression models were fitted to estimate both the mean and the Standard deviation at each gestational age.RESULTS:New Egyptian charts were reported for BPD, HC, AC, and FL. Reference equations for the dating of pregnancy were presented. The mean of the previous measurements at 12th and 41st weeks were as follows: (23.37, 98.72), (83.05, 336.12), (67.85, 332.57) and (12.50, 74.92) respectively.CONCLUSION:New fetal biometric charts and regression equations for pregnant women living in Port Said & Ismailia governorates in Egypt.

Second and third trimester estimation of gestational age using ultrasound or maternal symphysis‐fundal height measurements: A systematic review

“…Another 41 articles were considered from other sources, of which 17 were included. The final analysis included 97 full‐text articles 2,17–111 published between 1974 and 2021 (Figure 1, Table S2). Most excluded studies (309 articles, including 18 conference abstracts) did not report an equation to estimate mean or median GA from given measurements or tested an existing formula rather than reporting a new formula (Figure 1).…”
