Many parents want to know the weight of the upcoming baby in advance. It is also desired to know the health of the baby, and weight calculation helps in better monitoring of birth and reduces health risks to both mother and baby.
Dr. Max Mongelli’s study was carried out in order to estimate the weight of the baby/fetus on birth, few months prior to the actual birth event. The study involved 276 women. The birth or delivery from all the women was achieved in the next 35 days. For estimating and forecasting the fetal weight, the following techniques and measures were used:
● Hadlock formula, femur length, and abdominal circumference
● The Campbell formula that involved measuring the circumference of the abdomen
According to the extrapolation techniques and measurements, it can be hypotheses that the median weight: fetal weight ratio remains uniform and consistent throughout the 3rd trimester of the gestational period. Hence the weights observed and recorded were either left unchanged or were recorded on the basis of extrapolation, for the subsequent delivery. The weights recorded by the above-said methods were also compared with the technique given by researchers Spinnato and his colleagues. Later the non-parametric (tests that make fewer assumptions and are also known as the distribution free tests) were used and the weight predictions were analyzed for their accuracy, by comparing them to the real birth weights.
Results of the test, study, and analysis
While the Spinnato method suffered from 8.8% mean and systematic errors, the Hadlock method suffered from around 5.9% error. When no adjustments were made, the error was around 6.5%. All kinds of errors that occur randomly were also reduced and stood at around 11.2%, the earlier figure is 12.3%. When Campbell formula was used, the error was around 3.8%. The methods used also produced lesser absolute errors.
Conclusion of the study and test
During pregnancy, an ultrasound prediction or estimation of the delivery-time fetal weight should be done. This weight can be extrapolated and projected so that the birth weight at delivery can be calculated. The forecasted weight should also take into account the time lapse, which would occur in between the ultrasound and the delivery time. The method and technique that has been detailed and described above can easily find out the birth weight of the baby with least of errors and possesses excellent accuracy.
