[Developing parameters for predicting macrosomia].
OBJECTIVE
To identify appropriate fetal growth parameters that can be used in clinical practice for predicting macrosomia.


METHODS
Clinical data of 108 macrosomia babies and 108 babies with normal birth weight who were delivered in 2007 in Sichuan Provincial Hospital for Women & Children were collected and compared. The parameters for the comparisons included maternal abdominal circumference (MAC), fundal height (FH), and fetal diameters measured by ultrasonic imaging such as biparietal diameter(BPD), head circumference (HC), femur length(FL), and abdominal circumference(AC).


RESULTS
Maternal fundal height, fetal biparietal diameter, and biparietal diameter plus femur length produced greater than 0.64 of receiver operator characteristic (ROC) curve area for predicting macrosomia (P < 0.05), with a diagnostic index of 143. 5%, 138. 7% and 149.4%, respectively. Other parameters produced less than 0.63 ROC area for predicting macrosomia, with no statistical significance.


CONCLUSIONS
Maternal FH, BPD and BPD plus FL are relatively sensitive parameters for predicting macrosomia.
