Medical literature clearly showed its main drawbacks: A the number of patients considered in the studies some thousandth is low with respect to the total number of newborn per year about 160 Millions in 2013 in the world; B patients considered in the studies are not representative of the variety of anthropometrical factors due to ethnicity, familial aspects, and other relevant internal and external factors; C the commonly used growth curves are up to five decades old; they are not updated for the current population and they are not suitable to investigate temporal trends and dynamic aspects in fetal growth curves. Conclusions This research has developed models to more accurately predict estimated foetal weight at a given gestational age in the absence of ultrasound machines and trained ultra-sonographers. Objective to assess the fetal size and. Cases with low birth weight, preterm delivery, or other prenatal complications were not excluded from analysis.

The mean has been estimated by the fitted values from an appropriate polynomial regression curve of the measurement of interest on gestational age. There will be an improvement in fit as higher-order terms are added, but because these terms are not theoretically justified, the improvement will be sample-specific. However, a difference of one or two days gestational age can alter a Downs screening result from high chance to low chance or vice versa.
