| description | Objective: To establish reference charts for fetal biometric parameters in a non-selected risk
population from Uberaba, Southeast of Brazil. Methods: A retrospective cross-sectional
study was performed among 5656 non-selected risk singleton pregnant women between
14 and 41 weeks of gestation. The ultrasound exams were performed during routine visits
of second and third trimesters. Biparietal diameter (BPD) was measured at the level of the
thalami and cavum septi pellucidi. Head circumference (HC) was calculated by the following
formula: HC = 1.62*(BPD + occipital frontal diameter, OFD). Abdominal circumference
(AC) was measured using the following formula: AC = (anteroposterior diameter + transverse
abdominal diameter) × 1.57. Femur diaphysis length (FDL) was obtained in the longest
axis of femur without including the distal femoral epiphysis. The estimated fetal weight
(EFW) was obtained by the Hadlock formula. Polynomial regressions were performed to
obtain the best-fit model for each fetal biometric parameter as the function of gestational
age (GA). Results: The mean, standard deviations (SD), minimum and maximum of BPD
(cm), HC (cm), AC (cm), FDL (cm) and EFW (g) were 6.9 ± 1.9 (2.3 – 10.5), 24.51 ± 6.61
(9.1 – 36.4), 22.8 ± 7.3 (7.5 – 41.1), 4.9 ± 1.6 (1.2 – 8.1) and 1365 ± 1019 (103 – 4777),
respectively. Second-degree polynomial regressions between the evaluated parameters
and GA resulted in the following formulas: BPD = –4.044 + 0.540 × GA – 0.0049 × GA²
(R² = 0.97); HC= –15.420 + 2.024 GA – 0.0199 × GA² (R² = 0.98); AC = –9.579 + 1.329 ×
GA – 0.0055 × GA² (R² = 0.97); FDL = –3.778 + 0.416 × GA – 0.0035 × GA² (R² = 0.98) and
EFW = 916 – 123 × GA + 4.70 × GA² (R² = 0.96); respectively. Conclusion: Reference charts
for the fetal biometric parameters in a non-selected risk population from Uberaba, Southeast
of Brazil, were established. |
