SOSA OLAVARRIA, Alberto  and  ALVAREZ MOYA, Eulolio. Comprehensive biometric index for fetal growth assessment. Rev. peru. ginecol. obstet. [online]. 2021, vol.67, n.2, 00002. ISSN 2304-5132.

Assessing fetal growth and its deviations is a challenge for the physician who uses ultrasound fetal biometry to estimate gestational age and fetal weight, sometimes resulting in a prediction that deviates from reality.


: To process the data provided by seven authors, applying an integral biometric index formula, to confirm the possibility of coincidence between all the data obtained.


: Processing of head circumference (CC), abdominal circumference (CA) and femur length (LF) measurements according to gestational age published by 7 authors, to calculate the biometric index using the formula [CAF= (CC + CA) -LF].


: Polynomial equations were obtained for each group of data separately and finally the global data, correlating the values of the index and gestational age, obtaining the curvilinear correlation coefficient, with R² = 0.99 (p < 0.05).


: The comprehensive fetal growth index is proposed as a tool to verify fetal growth through sequential evaluation, regardless of the origin and characteristics of the population under study.

Keywords : Fetal growth; Biometry; Ultrasonography.
