| Objective:According to investigating the dietary nutrition intake during pregnancy and all kinds of nutriment standards of Urumqi Han Chinese pregnant women, to understand pregnant women and folic acid, calcium, iron, zinc and other mineral known use, understand the Han Chinese to the region can affect the health of pregnant women and fetus, in-depth study for pregnant women to nutrition and health, to promote Xinjiang Han Chinese pregnant women so as to provide basis of eugenic and superior nurture. Method:This topic selection of pregnant women is relatively dense autonomous region health care of women and children’s nutrition clinic as, deals in April 2014-September 2014, in the infested JianKa and make regular prenatal obtain informed consent, the questionnaire survey to 2310 cases of Han Chinese pregnant women to conform to the conditions of the Han nationality is different at the same time keep track of them pregnant women during pregnancy, eventually tracked 2009 cases of pregnant women.1. Adopt the way of face to face questionnaire asked the respondents basic situation investigation.2.24 hour dietary retrospective method is adopted to improve the dietary survey, and published in 2013, Chinese residents’ daily dietary reference intake of nutrients (DRI) s comparative analysis.3. Determination of hemoglobin H (b), the determination of serum folic acid, calcium, iron, zinc.4. Use SPSS 17.0 statistical software for survey and lab data analysis, composition ratio, mean of the statistic description, F test and x2 test and the multi-factor binary Logistic regression analysis. Results:1) The basic situation:a total of 266 people in the early stages of pregnancy, the participants at the middle 814, late pregnancy, a total of 929 people, the highest proportion of late pregnancy, the proportion of 50%. Age are mainly composed of 25 to 29 years old, the proportion is 36.73%; Cultural degree is given priority to with college degree and above, the proportion is 46.14%; BMI is given priority to with 18.5-24 before childbirth, the proportion is 63.91%; 2) Pregnant women between 25 and 29, level of education in the college of professional women, for folic acid, calcium, iron and zinc knows, take the best. Different age, culture degree and the career of folic acid, calcium, iron to know use comparison,, the difference was statistically significant (P< 0.05).3) And published in 2013, Chinese residents’daily dietary reference intake of nutrients (DRI) s, vitamin A than standard is more serious. Calcium, iron and zinc intake below RNI60%, inadequate intake. Vitamin D, Vitamin B12, folic acid intake below RNI30%, inadequate intake. Different protein and carbohydrate intake during pregnancy is lower than the recommended standards. The distribution of different dietary source of iron during pregnancy pregnant women showed that most of dietary iron from plant foods, absorption rate is low.4) Nutrition and biochemical indexes:pregnant women pregnant early H b level average (104.15±0.94) g/L, mid pregnancy H b average level for (103.82±0.56)g/L, H b level average for late in pregnancy (103.69±0.55) g/L. Pregnancy periods H b horizontal comparison, the difference was statistically significant (P< 0.05). Compare the incidence of anemia in pregnant women pregnant periods, the difference was statistically significant (P< 0.05). Different serum folic acid during pregnancy, pregnancy serum calcium, iron, zinc, there was statistically significant difference (P< 0.05). Pregnant women with pregnancy increases, the H b level will be reduced gradually, but the serum folic acid, calcium, iron and zinc content has no change.5) Influence factors analysis:older pregnant women, livestock and poultry, vegetables intake inadequate intake too low, folic acid, vitamin B12 and insufficient iron intake can lead to pregnant women H b level, serum folic acid, calcium, iron and zinc content decreases, but the higher cultural level and professional can reduce the pregnant woman anemia, folic acid, the incidence of serum calcium, iron and zinc. Conclusion:1) Age, culture level, occupation, pregnancy body mass index (BMI) may be the main factor that can affect the health of pregnant women.2) Pregnant women folic acid, calcium, iron and zinc with high awareness, different ages, different cultural level and professional distribution,24-29, high culture level and professional distribution of pregnant women, know taking is higher.3) Pregnant women with pregnancy increases, the hemoglobin content in the body is gradually reduced, and the serum folic acid, calcium, iron and zinc content increases with pregnancy has no obvious change.4) Pregnant women culture degree, occupation distribution, and vitamin B12, folic acid, iron, livestock and poultry and vegetables food intake is pregnant women serum folic acid, calcium, iron and zinc deficiency of main influence factors. |
