[Risk factors for fetal macrosomia].

Aim: To determine the influence of some of the risk factors on fetal macrosomia.

Materials And Methods: A retrospective study was provided at the Department of Obstetrics and Gynecology, Medical University, Pleven, from January, 1, 2001 to December, 31, 2002 over 625 deliveries: 225 cases of fetal macrosomia--fetal birth weight (FBW) more than 4000 g and/or over 90. percentile (macrosomic group--MG) and 400 cases of singleton term newborns--with FBW between 10. and 90. percentile (nonmacrosomic group--NMG). Analysis included influence of: maternal age, height, prepregnant weight, BMI, weight gain and weight before delivery, previous delivery of macrosomic infant, maternal diabetes mellitus, fetal sex and gestational age.

Results: A comparative analysis of data for both of groups was performed. It was found significant correlation (p = 0.001) for influence of maternal age (r = 0.34); height (r = 0.33); prepregnant weight (r = 0.42); BMI (r = 0.32); weight before delivery (r = 0.49); weight gain (r = 0.34); previous delivery of macrosomic infant (r = 0.41); maternal diabetes mellitus (r = 0.54); fetal sex (r = 0.37) and gestational age (r = 0.39). Correlations are different in both of groups.

Conclusion: Positive correlations between analysed factors and delivering of macrosomic infants and differences in both of groups suggest that analysed factors can't explain completely fetal macrosomia.
