Abstract：Objective To analyze risk factors for non-diabetic fetal macrosomia to predict fetal maerosomia and select the appropriate mode of delivery. Methods Retrospective analysis was used with 368 eases of non-diahetic fetal macrosomia in Nanjing General Hospital of Nanjing Military Command between January 2006 and December 2007 and clinical data on maternal age, height, prepregnancy weight, gestational age, birth weight, gestational weight gain, height of uterus, abdominal circumference, femur length (FL), biparietat diameter(BPD). Statistical analysis used the ehi-squared test, correlation, regression analysis, and as appropriate. P≤0.05 was considered significant. Results The incidence rate of non-diabetic fetal macrosomia was 13.23% (368/2781). Prepregnancy weight, birth weight, gestational weight gain, height of uterus, abdominal circumference, BPD, FL, uterus height plus abdominal circumference, BPD + FL were correlated with fetal macrosomia, but the most significant correlation was height of uterus and BPD + FL. There was no significant difference in delivery mode, compared macrosomia with normal birth weight infants. Conclusion The combination of BPD + FL can improve prediction of fetal maerosomia. Fetal maerosomia is not an absolute indication of cesareansecetion.
