Cranio-spinal length: predictor of fetal growth and the trophic condition of the newborn
Abstract
Background: age and fetal growth are determined by head length or cranial-spinal length between weeks 5 and 10 of gestation and then a combination of measurements of other biometric variables is used.
Objective: to identify the correlation of biometric variables and trophic condition at birth with the cranial-spinal length of the first trimester.
Methods: an investigation with a retrospective longitudinal analytical design was carried out in Villa Clara province; it was appealed in the period from January 2013 to October 2018. The population consisted of 6050 pregnant women. The sample was made through an intentional non-probabilistic sampling by criteria, consisting of 3 910 pregnant women. Data were obtained from genetics consultation record books from selected health areas. In the analysis, Pearson's linear correlation coefficient, Spearman's Rho, and scatter diagrams were used.
Results: there was a correlation between the cranial-spinal length with the variables and with the trophic condition of the newborn. The graphs that defined the trajectory of the biometric variables from the second trimester to delivery showed compaction of the values up to week 25 and dispersion between week 25 and 30 with differential features in them.
Conclusions: the correlation found of cranial-spinal length with biometric variables and with the trophic condition of the newborn demonstrates the usefulness of the use of this variable in the evolution of pregnancy by both the obstetrician and the comprehensive general practitioner; particularly in pregnant women in whom some growth alteration is suspected. The results obtained motivate further study by subdividing the sample into subgroups such as those affected by diabetes mellitus or arterial hypertension or another, particularly because there is no information on it in the literature.
