| Objective:To investigate the dietary intake status of Uyghur pregnant women, explore the folic acid, vitamin B6, B12 levels and its influence factors, provide basis for maternal health education and reasonable nutrition and balanced diet. Methods:Using the cluster sampling method, randomly selected 1411 cases of Uyghur pregnant women carried out basic condition survey, dietary survey, physical examination and a follow-up survey was conducted on 397 cases of early pregnant women, detection of hemoglobin by cyanide methemoglobin method, using enzyme linked immunosorbent assay method for the detection of folic acid, vitamin B6, B12, homocysteine cysteine. V2.7.13 nutrition calculator treated with dietary survey data, compared with the 2013 version of "China DRIs", statistical analysis using SPSS19.0. Results:1) dietary composition:grain 397.35g, vegetables 184.86g, fruit 138.17g, meat 67.23g, fish 0.18g, egg 24.53g, dairy 6O.I5g, beans 9.19g, oil 26.87g, salt 9.03g.2) early and late pregnant women the energy and nutrients intake accounted for DRIs percentage respectively for energy(105.72%,83.80%), protein (109.33%,83.80%), calcium (30.86%,24.76%), potassium (69.80%,72.07%), sodium(223.99%,213.86%), iron (275.30%,214.86%), zinc(l 17.16%,120.42%).selenium (52.69%,50.95%), iodine (83.80%,85.17%), vitamin A(106.77%,88.90%), vitamin Bi (92.50%,73.33%), vitamin B2 (58.33%,48.00%), vitamin B6 (85.00%,90.91%), vitamin C (64.00%,57.23%), vitamin E(100.64%,101.64%), folic acid (13.18%,12.82%). Early and late pregnant women ingested proteins (26.22%,29.23%), calcium (21.88%,13.10%)and iron (12.91%,13.27%)from animal foods.3) maternal folate related knowledge awareness rate of 25.23%, the rate of taking 8.50%; different age, educational level, family income and occupation in maternal folate related knowledge awareness difference was statistically significant (P<0.05).4) the nutritional biochemical index:397 cases of pregnant women hemoglobin average(119.42+13.90)g/L, the total positive anemia rate was 18.89%, compared with hemoglobin levels in early and late (P<0.05), compare the detection rate of anemia (P<0.05); the maternal folate average levels was (9.15+4.22) nmol/L, the total lack of detection rate 70.53%, compare the folic acid level of early and late (P<0.05), folic acid deficiency detection rate (P<0.05); the average level of vitamin B6 (94.53+26.77) nmol/L, compare the levels of vitamin B6 in early and late (P>0.05); the average level of vitamin B12 (438.98+125.93) pmol/L, the total excess detection the rate was 32.24%, compared with early and late vitamin B12 levels (P>0.05); the maternal average plasma Hcy level was(11.93+2.76) mol/L, the total HHcys positive rate was 17%, early and late compared with plasma Hcy (P＜0.05), HHcys detection rate comparison (P＜0.05). Conclusion:1) The diet composition of pregnant women is unreasonable, vegetables, fruits, eggs, milk and beans intake is low, fish intake is almost 0, salt intake was higher.2) Three major thermogenesis nutrients thermogenesis proportion is appropriate. Pregnant women K, selenium and vitamin B1, vitamin B2, vitamin C, calcium and folic acid intake was lack.3) Pregnant women’s serum folic acid levels is low, folate deficiency rate is higher, the influence factors of age, level of Hcy, and the intake of fruits, folic acid, vitamin C and calcium.4) Pregnant women’s vitamin B6, B12, Hcy average levels were in the normal range. |
