| Objective1 Explored the effect of personalized dietary guidance on the status of nutritional intake during pregnancy, in order to provide a reference guide nutritional meals during pregnancy.2 Explored the effect of personalized dietary guidance during pregnancy on pregnant women weight gain, pregnancy complications, neonatal birth weight and mode of delivery,in order to control the excessive increase in body weight of pregnant women and reduce the incidence of large children, and reduce perinatal complications.Methods200 women were selected as the research group who were the first preganace and a single child and have took part in the training of pregnancy in Maternal and Child Health Hospital, Hebei District,of tianjin,from september of 2008 to october of 2009. According to the BMI of progestation or the BMI before 12-week pregnancy we divided them into three groups of normal weight(BMI) (18.5 - 22.9), over weight (BMI 23 - 24.9),and obesities(BMI≥25).Experimental group and control group are both take part in the prenatal care classes.and at the same time we provide personalized nutritional guidance to experimental group. The two group accept nutritional guidance in April and July during pregnancy and record a dietary survey of 5 days.Then we input the collected nutrition data into computer software (pregnant version,In order to analy the condition of dietary intake of pregnant women. According to the results of nutrition, combined with the specific situation of pregnant women.we carry out one on one nutrition analysis to experimental group.At the same time we monitor weight gain during pregnancy, timely adjust to thermal energy and various nutrients supply until delivery. Compared to energy and the dietary intake of nutrients of the two groups of pregnant women and weight gain, pregnancy complications, newborn birth weight and mode of delivery.Results1 Three groups of pregnant women's the main nutrient intake in the second trimester and late pregnancy:Compared to the intake of energy, protein, fat, calcium of the experimental group and control group, the difference was statistically significant (P＜0.05). Compared to the intake of other nurtrients, the difference was not statistically significant (P＞0.05). 2 Compared the three major nutrients of three groups of pregnant women in the second trimester and late pregnancy:The experimental group had the suitable proportion.The control group had high levels of fat intake and low levels of carbohydrate intake.3 Compared the weight gain of pregnant women in three groups:The experimental group:16.64±2.20 kg,15.02±3.45 kg,10.45±2.05 kg; The control group:19.56±5.84 kg,18.50±3.46 kg,17.00±3.21 kg.4 Compared the birth weight in three groups:The experimental groups are lower than the control groups. The experimental groups meet the WHO recommended the best birth weight are higher than the control groups.5 The GDM,PIH,Anemia,and huge child incidence:The experimental groups are lower than the control groups.6 Compared the mode of delivery in three groups:The cesarean section rate of the experimental groups is lower than the control groups.Conclusions1 We provide personalized dietary guidance to pregnant women, according to the different pre-pregnancy BMI of pregnant women. The results show the personalized dietary guidance to pregnant women during pregnancy had good clinical effects.2 The personalized dietary guidance made the pregnant women attain to a reasonable weight gain and increase delived appropriate birth weight fetal and the rate of huge fetal and reduce to pregnancy complications. |
