Correlational Studies Of Prenatal Nutrition Guidance And Pregnancy Complications Occurred

Pregnant women in pregnancy refers to the state of the particular physiological crowd, not only to maintain their nutritional needs, it also ensures that fetal growth and breast, the womb and the development of the placenta, need, at the same time for delivery and postpartum lactation do nutrition reserves. Pregnancy nutrition pregnancy outcome and fetus to growth and affect the health of adult, has always been the hot spot of the special attention. More than ten years, the amount of research on pregnancy nutrition during pregnancy and the practice of nutrition intervention results indicate that maternal nutrition to the pregnancy outcome will have a direct very important influence, malnutrition pregnant women can improve nutrition improve ideal pregnancy outcome, and maintain the mother’s health. Even so, whether it is a developing or developed country, premature birth rate, low birth weight and birth defects rate and other pregnancy complication rate is still very high, so the study of pregnancy maternal nutrients metabolic features and appropriate nutrients required for pregnancy nutrition intervention can provide the scientific basis and guidance.Appropriate pregnancy nutrition, relates directly to the pregnancy outcome, the fetus and infant physical and mental development. Pregnancy severe malnutrition, can cause fetal development within the obstruction, directly influence the birth of nutrition, such as low birth weight babies, immune function, reduce Prenatal nutrition surplus, also can cause intrauterine fetal development obstacle, easy to produce the overweight son, problems such as childbirth. War factors and climate factors and social development are can cause malnutrition during pregnancy. The crowd epidemiological studies found that during world war ii experience of regional hunger woman than not experienced postpartum and hunger woman in adulthood postpartum and cardiovascular diseases such as diabetes, the probability of increase. At that point, during pregnancy, poor nutrition may be some adulthood of disease cause. At the same time the reasonable nutrition therapy during pregnancy can reduce pregnancy complications. The subject has confirmed the gestation nutrition treatment can reduce late pregnancy with hypertension disease, enhance the pregnant woman serum protein level, reduce the occurrence of pregnant women dropsy. Results:1. random into the conditions of the pregnant women with88cases, lost to follow-up in3, lost to follow-up rate is3.4%;80cases of control group pregnant women. Two groups in age, height, body weight, at20weeks ago before childbirth BMI, occupation and cultural difference was statistically significant.2.In the protein intake, less than60%of the pregnant women can achieve nutrients recommended intake level, in the first time accept pregnancy after nutrition diet adjustment, reach the level of the proportion of nutrients recommend women increased. In addition, pregnant women in the early stages of pregnancy dietary fat intake percentage frequency are20%,89%of the pregnant women fat intake frequency ratio to30%, suggests that this study at present pregnant women there during pregnancy high fat intake phenomenon, after nutrition guidance to late pregnancy fat intake has declined.3.Pregnant women in the early stages of pregnancy iron, calcium, iodine, zinc intake were different degree and the lack of iron in the early stages of pregnancy performance is not obvious, calcium intake level with the increase of the pregnancy is increasingly deviating from the RNI. Many pregnant women in the early stages of pregnancy will appear iodine inadequate intake phenomenon, through diet supplement nutrition guidance after reach the correct value most intake, have a few have excessive intake phenomenon.4.The nutrition related obstetrician pregnancy the incidence of complications and cesarean section rate was lower than that in control group (P<0.05), the body composition analysis the nutrition guidance pregnant women birth weight significantly higher than that in control group (P<0.05), postpartum blood loss was not statistically significant differences between the two groups.5. Pregnant women with the increase of the middle body mass, BMGI, BMR, FFM, TBW and birth weight is correlation (P<0.05), late in pregnancy BMGI pregnant women, BMR, FFM, TBW and birth weight is correlation (P<0.05). Among them BMGI, FFM and birth weight is a significant positive correlation (P<0.01).Conclusions:1. Nutrition guidance during pregnancy by adjusting the intake of nutrients pregnancy meet the pregnant woman and the demand of normal fetal development;2. To diet and exercise survey and prandial habit survey as the foundation, the body composition of control target for the pregnancy nutrition guidance to a reasonable control the quality of the pregnant woman body to increase the reduced the son born and great maternity complications has great social significance;3. Pregnant women pregnancy weight gain index, to fat weight is birth weight of a predictor.
