Analysis of Research Reports In France, the number of macrosomic baby delivery (infants with a birth weight above 97th percentile) for gestational age has increased from 2.3% to 2.5% from 1994 to 2008. Most publications focused on neonatal and only few studies focused on maternal and perineal outcomes. The study was to investigate whether or not the policy of induction of labor for women with large baby might reduce the maternal morbidity. The purpose of this paper will interpret the statistical significance of the study. This cohort study used the AUDIPOG sentinel network database, which “comprises public and private maternity units from every region in France” (Vendittelli, Françoise, et al, 2014). The database includes 411,734 pregnancies between 1994 and 2008. The ineligible were those who deliveries before 37 weeks, multiple pregnancies, inappropriate fetal position, women with diabetes, and missing information of birth weight or sex. Therefore, only 3077 pregnancies with suspected large-for-gestational-age (LGA) fetus were eligible to participate (Vendittelli, Françoise, et al, 2014). LGA defined as “a neonate whose birth weight is at least 1.88 standard deviations (SD) higher than the mean (≥2 SD) for the infant’s gestational age and sex, that is, the 97th percentile for gestational age, based on data derived from the reference population included in our database. At 37 weeks, LGA was defined as 3,836 g for a boy and 3,691 g for a girl” (Vendittelli, Françoise, et al, 2014). Among the qualified participants (n=3077), the induction group consisted 199 pregnant women (n=199), the range for mother labors’ induced was between 37 weeks to 38 weeks six days. The control group (n=2878) was those mothers underwent induction of labor after 39 weeks (Vendittelli, Françoise, et al, 2014). The methods used in this study were chi-square tests
