Birth weight projection based on ultrasound measurements earlier in pregnancy may be better than standard prediction methods for obese women, researchers said.

One such method using ultrasound measurement at 34 to 36 weeks predicted birth weight within 20% accuracy in more than 90% of cases, reported Loralei Thornburg, M.D., of the University of Rochester Strong Memorial Hospital here, and colleagues in the July issue of Ultrasound in Obstetrics and Gynecology.

In their retrospective study, this gestation-adjusted prediction (GAP) method had lower sensitivity among morbidly obese women for the clinically important prediction of macrosomia, but could exclude macrosomia with more than 90% accuracy regardless of maternal body mass index.

Terry - this looks like a good research project for one of your students.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
