Study On The Evaluation Of Intervention Of Neural Tube Defects By Health Education

Objective: Neural tube defects are the most common central nervous system malformation among the fetal anomaly.It is the main reason for infant death and disability, which brings great suffering to society, personal one and family, and seriously threat to the health and quality of the population. By follow-up observation for two years, we collected the details about the knowledge on prenatal caring, dietary improving, health education and folic acid taking during pregnancy. The aim is to evaluate the effect of intervention and provide scientific basis for advancing the model of comprehensive intervention on NTDs.Methods: The study randomly selected Pingyao in Shanxi Province, Jiexiu, Qixian, rolls, Lingshi, the Yang six counties (cities) as a follow-up field study, nearly three years, the women of fetal NTDs fertility study, at first survey year (in December 2009 before) and the second 2 years (before December 2010) were followed up for one of its acceptance in the pre-pregnancy level, secondary interventions and related factors of the situation in the questionnaire. SPSS13.0 software with SAS8.0 and statistical analysis of the data, using the analysis method:χ~2 test,χ~2 trend test, rank sum test and so on.Results: (1) Incidence of neural tube defects 1.00%.(2)Prevention of NTDs knowledge: that of neural tube defects before and after the intervention in the intervention, the intervention group and control group byχ~2 test showed significant differences after the intervention NTDs awareness (78.5%) than before intervention (46.0 %) And control group (55.5%); eugenic advice to prevent NTDs and prenatal screening for prevention of NTDs before and after intervention by theχ~2 test was significantly (p = 0.020, p = 0.010), the intervention group and control group difference byχ~2 test No statistical significance; antenatal intervention to prevent NTDs before and after the intervention group and control group byχ~2 test were not significantly different.(3) Folic acid to take the situation: level of knowledge of folic acid about folic acid to prevent NTDs, pre-pregnancy, or heard of folic acid in pregnancy know folic acid in foods before and after the intervention in the intervention, the intervention group and control group differences were tested byχ~2 statistics significance; heard of folic acid before and after intervention byχ~2 test means found by a doctor or family planning staff, leaflets or brochures, promotional posters, or blackboard newspaper difference was statistically significant (p <0.05), the intervention group and control group through advocacy Single or brochures were significantly (p <0.05); taking folic acid before and after the intervention in the intervention, the intervention group and control group byχ~2 test showed significant differences, taking folic acid after the intervention rate (87.5%) higher than before the intervention (61.%) and the control group (78.5%).(4) Dietary change: The adjustment of diet byχ~2 test whether the difference was significant,χ~2 values and p = 9.598 and <0.001 for failure to adjust the dietχ~2 test to compare the reasons for the difference was significant,χ~2 values and p = 13.958 and <0.001, the case group and control group did not adjust the main reason is that the diet does not need improvement, mainly due to the intervention group improved, but the economy does not allow. The result is to increase dietary intake of meat, eggs, beans, vegetables, fruits, grains, seafood and pickles byχ~2 test to reduce the difference was significant.Comparing the results of early pregnancy intake frequency of fish meat, animal offal, eggs, beans, milk, vegetables, fruits, nuts and pickles, pickles, pickled byχ~2 trend testwas statistically significant difference.(5) Inspection during pregnancy: Inspection of the intervention during pregnancy: the first prenatal check the time, and the second time, showed that ultrasound before and after intervention, the intervention group and control group byχ~2 test was significantly (p <0.05); the number of prenatal care, ultrasound Inspections before and after intervention, the intervention group and control group byχ~2 test was significantly (p <0.05), pregnant women, prenatal care after the intervention of the number and frequency of ultrasound is higher than before intervention and control group.(6) Health education and genetic counseling: health education, post-intervention rate (95.5%) than before intervention (53.0%) and the control group (85.5%); before and after intervention through magazines or books and brochures, the intervention group and control Group received health education through brochures byχ~2 test was significantly (p <0.05), and place different agencies eugenic legacy Advisory differ among groups.Conclusion: (1) Pregnant women taking folic acid to prevent neural tube defects is an effective method.(2) Increaseing in knowledge level of neural tube defects in pregnant women, folic acid, prenatal testing and ultrasound examination, health education and genetic eugenics, can reduce the incidence of neural tube defects.(3) Health education as an intervention, can significantly change the behavior of pregnant women's diets.(4) Prenatal care and genetic counseling for changing behavioral conducive to the prevention of neural tube defects occur.
