Fetal growth in Bogotá, Colombia: a comparison with international and latin american curvesObjectives: to describe estimated fetal weight, biparietal diameter, head circumference, abdominal circumference, and femoral length in a sample of pregnant women and to compare them with the international curves.
Methods: a retrospective cross-sectional study was conducted on ultrasonographic data of singleton pregnancies between 16 and 39 weeks in Bogotá, Colombia, from February 2015 to November 2018. Fetal parameters were evaluated. Descriptive analysis of each biometric parameter was performed, followed by comparison the curves provided by INTERGROWTH-21st and Lagos.
Results: a total of 1133 sonographic reports were analysed. The means ± SDs of biparietal diameter, head circumference, abdominal circumference, femur length, and estimated fetal weight measurements at 16and 39 weeks were 34.7 ± 1.5 and 92.2 ± 4.4 mm, 122.2 ± 6.6and 318.0 ± 17.0 mm, 107.2 ± 6.8 and329.3 ± 34.6mm, 20.6 ± 2.8 and 73.5 ± 3.3 mm, and257.8 ± 20.9 and 3,115 ± 663.7g, respectively. The data were presented in graphs. AC and FL were the parameters that showed more statistically significant differences with international curves.
Conclusions: international reference charts analysed, show differences when fetal growth of this population was compared. The customized or local charts maybe are more useful to reach early detection of alterations offetal growth in each population.
