| Objective To study the effects of different pre-pregnancy body mass index (BMI) and gestational weight gain(GWG) on pregnancy outcomes and neonates. Methods A total of 349 pregnant women who underwent maternity examination and in-patient delivery in the Second People's Hospital of Hefei from January 2016 to December 2016 were selected as the research object, and divided into low body mass group (BMI<18.5 kg/m2, 50 cases), normal body mass group (18.5 kg/m2 ≤ BMI<25.0 kg/m2, 260 cases), overweight and obesity group (BMI ≥ 25.0 kg/m2, 39 cases) according to BMI. Then according to the differences of GWG, they were divided into low GWG group (41 cases), appropriate GWG group (133 cases) and excessive GWG group (175 cases). The delivery mode, pregnancy complications and neonatal outcomes of pregnant women in each group were compared. Results The incidences of cesarean section, gestational diabetes mellitus, postpartum hemorrhage, premature rupture of membranes and macrosomia were higher in overweight and obesity group than those in the other two groups, and the difference was statistically significant (P<0.05). The incidences of maternal anemia,neonatal preterm birth, low birth body mass and fetal distress were higher in low body mass group than those in the other two groups, and the difference was statistically significant (P<0.05). The incidences of cesarean section, postpartum hemorrhage, premature rupture of membranes and macrosomia in group with excessive total weight gain during pregnancy were higher than those in the other two groups, and the difference was statistically significant(P<0.05). The incidences of gestational diabetes mellitus, preterm delivery and fetal distress in group with too little total weight gain were higher than those in group with too much GWG and appropriate GWG during pregnancy, and the difference was statistically significant (P<0.05). Conclusions Clinicians and pregnant women should fully recognize the effects of abnormal pregnant weight and abnormal weight gain during pregnancy on mothers and babies, and strictly control the body mass index before pregnancy and the total weight gain during pregnancy in the appropriate range. |
