Research Highlights Problems Of Predicting Birth Weights In Obese Mothers But Finds GAP Method Very Accurate

“Researchers have found what they believe to be the most accurate way of predicting the birth-weight of babies born to the growing number of obese mothers, according to a study in the UK-based journal Ultrasound in Obstetrics and Gynecology. Experts from the University of Rochester Strong Memorial Hospital in Rochester, New York, USA, have recorded accurate results in more than nine out of ten cases using the gestation-adjusted projection method (GAP). The GAP method uses a range of ultrasound measurements, taken when the mother is 34 to 36 weeks pregnant, and a mathematical formula to determine whether the baby is larger than the average size of babies for its gestational age. This data is then used to predict the final birth weight. GAP is very useful when a pregnant woman is obese, as this often makes it difficult for medical staff to obtain a clear ultrasound image of her baby.”
