| Objective:To investigate the January2011-December2011, the Urumqi Maternal and Child Health Hospital obstetric regular check-ups and hospital delivery, age in single births in the35-year-old full-term581cases Uygur primiparous women pre-pregnancy body mass index, weight gain during pregnancy exponential growth relations, analysis of the impact of body weight on the outcome of pregnancy and pregnancy outcome. Methods:A retrospective study method was used, according to pre-pregnancy weight, and body mass index (BMI) range, the patients were divided into four groups:weight loss group (BMI<18.5kg/m2); normal weight group(BMI:18.5-24kg/m2); overweight group(BMI:24~28kg/m2); obese group(BMI≥28kg/m2),according to the increase BMI of pregnancy weight(ABMI), the patients were divided into three groups:△BMI<4;6≥△BMI≥4;△BMI>6. Analyzed the mode of delivery, birth weight, pregnancy complications and complications. Count data using the chi-square test. Results:Uighur pregnant women before pregnancy body quality, pregnancy weight gain and cesarean section rate differences are statistically significant (P<0.05); huge children in pre-pregnancy body mass index for overweight chance of pregnancy body mass index increased significantly compared with the other three groups, increase in differences in the incidence of the great children’s influence was statistically significant (P<0.05); pre-pregnancy body mass index difference was statistically significant (P<0.05) in the incidence of low-quality children’s pre-pregnancy body mass index differences, pregnancy differences in the growth of body mass index with preeclampsia incidence of gestational diabetes difference was statistically significant (P<0.05). Conclusion:Uighur primiparous women overweight pre-pregnancy body mass index (BMI:24to28kg/m2), obesity (BMI≥28kg/m2) and pregnancy body mass index growth rate is too large adverse effects on pregnancy outcome. |
