ABSTRACT
Introduction: predicting small-for-gestational-age births since their early stages is a health action that deserves to have technological tools of proven efficiency that guarantees it.Objective: to determine predictive capacity of the biometric measurements and the formulas of estimation of fetal weight for small-for-gestational-age births.
Methods: a retrospective study of all single pregnancies seen at «Chiqui Gómez Lubián» policlinic of Santa Clara was carried out from January, 2009 to December, 2014. Receiver operating characteristic curves were constructed to measure fetal biometric parameters in each trimester and to calculate formulas of estimation of fetal weight, as well as, area under the curve was showed as a predictive capacity for small-for-gestational-age births; cut-off points were determined and contrasted with tables of national reference.
Results: head circumference in the second trimester of pregnancy, abdominal circumference in the third trimester, and Hadlock's formula, which included these two measurements for the third trimester, were the biometric measurements and the formulas of estimation of fetal weight, respectively, with better area under the curve. Cut-off points found in this study allowed a better classification for small-for-gestational-age births than the tables of reference in Cuba.
Conclusion: biometric measurements and formulas of estimation of fetal weight can predict small-for-gestational-age births since early stages. Cut-off points for the local population allow a better classification than the ones used until now.
