Abstract
Objective: Evaluate fetal growth measured by uterine height and its association with fetal growth deviations and patient data. Methods: Cross-sectional study of patients attended by the obstetrics services during the period from 2008 to 2021. Data from anamnesis, physical examination, ultrasound assessment of fetal growth in all trimesters and uterine measurement of low-risk pregnant women were used in the study. Results: 883 pregnant women with an average age of 25.5 + 7,29. Uterine heights were divided into percentiles according to gestational week intervals and were thus identified in centimeters: 17.0 + 2.59 (16-20 weeks; 4th month), 21.0 + 2.27 (20-24 weeks ; 5th month), 24.9 + 2.45 (24-28 weeks; 6th month), 28.4 + 2.49 (28-32 weeks; 7th month), 32.00 + 2.26 (32-36 weeks; 8th month) and 34.00 + 12.00 (> 36 weeks; 9th month). Uterine height was associated with fetal weight (p<0.05). Conclusion: We identified that the curve of uterine height X fetal weight X gestational age can be used in monitoring low-risk pregnant women, since fetal weight increases with gestational age.
