METHODS:

A total of 5487 serum samples from pregnant women who simultaneous detection for the first time from January 2013 to December 2016 in Beijing were enrolled in the study, then high performance liquid chromatography(HPLC) method was used to determine the concentration of serum vitamin A and vitamin E, and it was compared with serum concentrations of vitamin A, vitamin E in normal people. Qualitative analysis of the trend of vitamin A and vitamin E nutrition in pregnant women from 2013 to 2016.

RESULTS:

From 2013 to 2016, the serum concentration of vitamin A(median(four guantile sapcing))was 1. 23(1. 05-1. 44), 1. 40(1. 19-1. 68), 1. 51(1. 30-1. 75) and 1. 54(1. 30-1. 79) μmol/L, respectively. The total abnormal rate for four years running was 22. 3%, 14. 6%, 8. 1% and 8. 6%, respectively, with main performance of lacking(21. 6%, 13. 4%, 6. 8% and 6. 4%, respectively). The serum concentration of vitamin E(median(four guantile sapcing)) was 36. 00(28. 80-45. 00), 30. 72(25. 44-37. 92), 30. 00(24. 96-35. 52) and 31. 68(26. 40-37. 92) μmol/L, respectively. The total abnormal rate from 2013 to 2016 was 17. 4%, 7. 5%, 3. 6% and 4. 3%, respectively, with excess(17. 4%, 7. 5%, 3. 6% and 4. 0%, respectively) as the main performance.
