Prepregnancy Overweight/Obese Pregnant Women Dietary Intervention On Dietary Intake And Pregnancy Outcome

Objective: The overweight/obese pregnant women dietary intervention(low GI)+ exercise close to the recommended intake of pregnant women to control weight gain during pregnancy in all stages of pregnancy dietary intakes to the maximum extent,prevent GDM complications of pregnancy,macrosomia,cesarean section and other adverse pregnancy outcomes and improve pregnancy outcome.Methods: From June 2014 to December 2016 in the First Affiliated Hospital of Xinjiang Medical University and the autonomous region of maternal and child health hospital obstetrics outpatient regular examination during pregnancy,early pregnancy(gestational age less than 12 weeks)of overweight/obesity primipara 300 people as the research object,carries on the investigation and intervention on the.The survey included: general condition,lifestyle,physical examination,dietary survey,dietary intervention,exercise intervention and health education.Results:This study obtained seven dietary patterns were aquatic products(eggs pattern in aquatic products,poultry,dairy products,pasta,rice,the staple food(mainly)model to class,potato,rice grains,fruit cake type)mode(with cakes,fruits,nuts,fungi)beans mode(in nuts,beans mainly),vegetables(pickles pickles and vegetables in model based),oil(Miscellaneous mode to drink beverages,edible oil,meat based Zamian)mode(red meat,white meat,animal offal.).Low GI dietary intervention of two groups of pregnant women in late pregnancy energy,fat,protein and dietary fiber daily intakes were different and the difference was statistically significant(P<0.05).There was no significant difference between the two groups of pregnant women in late pregnancy carbohydrate and cholesterol daily intake(P>0.05).The intervention group and the control group of pregnant women between daily intakes of vitamin A,calcium,magnesium,iron and copper(P<0.05).The average daily intake of two groups of maternal vitamin C,vitamin D,vitamin E,folic acid,phosphorus,potassium,sodium,zinc,manganese,selenium and iodine had no statistical significance(P>0.05).The outcome of pregnant women: the control group maternal pregnancy weight gain,GDM and the incidence of preterm birth in pregnant women than in the intervention group(P<0.05).Two groups of pregnant women of gestational age,HDCP,birth,cesarean section and premature rupture of membranes was not significantly different(P>0.05).Neonatal outcome: two groups of pregnant women in preterm infants,low birth weight and macrosomia incidence rate difference(P<0.05),stillbirth and neonatal asphyxia rate had no significant difference(P>0.05).The control group of pregnant women in head circumference than in the intervention group maternal neonatal head circumference(P<0.05).Two groups of neonatal body weight,body length,there was no significant difference between the 1 minute Apgar score,5 minute Apgar score(P>0.05).Conclusion:To control the total energy intake and weight gain during pregnancy is an important measure to ensure a good pregnancy outcome.
