Effects Of Diet Intervention On Emergence Of Pregnancy-induced Hypertension Syndrome

Pregnancy-induced hypertension syndrome(PIH)is a disease that happens in the women's gestation period exclusively.As a disease that threatens the life of women and babies,PIH usually happens at 20 weeks after pregnancy or after,and is characterized as hypertension,proteinuria,edema and other dysfunctions.The morbidity of PIH in China is 9.4 percent in average,and from the inspection datas on some areas of China,the maternal mortalitycaused by PIH is 7.7 per 100,000 people,which accounts for 10 percent of maternal mortality.Because PIH pathogenesis is complex and not yet fully clear,there is no specific effective clinical prevention and treatment for PIH.Since the last decade of 20 th century,more and more studies have suggested that the emergence and development of PIH is related with overnutrition and nutrition deficiency during pregnancy.Although nutrition during pregnancy is gaining more attention than ever,the fact is,there is a lack of education among pregnant women regarding nutrition,which prevents them forming a suitable structure for food intake,so that there is a high frequency of diet bias or food abuse,which can break the balance of nutrition in pregnancy.Therefore,it is necessary to provide guidance for the pregnant women in rational diet from early pregnancy stage.Objectives:1 To investigate the influence of diet intervention on PIH women,so as to form the basis for diet guidance in pregnancy.2 To investigate the effect of diet intervention on the emergence of PIH,and the relationship between the nutrition intake and the PIH the nutrition intake that can lower the morbidity of PIH..Methods:A controlled trail is designed,in which 100 pregnant women who received antenatal care in Xingtai People's Hospital during January to November of 2016 and who were chosen to be the samples in intervention group in.The chosen ones were willing to receive diet intervention during their pregnancy.Apart from the normal inspections,they received diet intake intervention from early pregnancy to delivery.At the same time,100 pregnant women were randomly chosen to form the control group.They received the normal antenatal inspection but did not receive guidance in diet intake.In every antenatal inspection,the pregnant women were asked to report their diet intake and fill a form for diet intake survey(about their diet intake in recent 3 days),and input the collected data to the nutrition analysis instrument to analyze their nutrition intake.For the pregnant women in the intervention group,the researcher assigned different diet plans according to their diet and body weight.The interventions include:Personalized diet intake planTime-based adjustment to the diet intake planThe transferring of nutrition knowledgeEnhancing the health of pregnant womanThe researcher required the pregnant women to measure their body weight and blood pressure during the whole course of pregnancy,and based on which to calculate the morbidity of PIH.Based on the findings,the researcher further studied the relationship between nutrition parameters and PIH.Results:1 There was no significant difference between the two groups in the nutritional attitude,nutritional behavior and the level of nutritional knowledge(P>0.05);The nutritional attitude,nutritional behavior and nutrition knowledge scores of the pregnant women in the intervention group were higher than those of the early pregnant women after receiving the nutrition dietary guidance(P<0.05),and significantly higher than the control group(P < 0.05).2 The increasing of body weight in control group is higher than that of intervention group(P<0.05).3 Two groups of pregnant women in late pregnancy on the daily intake of various nutrients calculation survey,the intervention group was significantly lower than the energy intake of pregnant women pregnant women in the control group(P<0.05),while in the aspect of protein? potassium and calcium intake,the intervention group was significantly higher than the control group(P<0.05),vitamin C,potassium and iron intake,no significants difference between the two groups.4 The morbidity of PIH in intervention group is significantly lower than that of control group(P<0.05).Conclusion: the guidance on pregnant women's diet intake can make their intake of nutrition more rational,and lower the morbidity rate of PIH to some extent,which may be related with the intake of high protein,high calcium and low sodium food.
