[Total diet study on certain nutrients in Shanxi regions with a high incidence of birth defects]

To analyse the dietary nutritional intake level in Shanxi regions with a high incidence of birth defects.

Using the total dietary study method in the pilot regions of the project "Intervention program on birth defects" in Shanxi province. The analytical samples were obtained in different areas by food consumption survey, the dietary nutrients related to birth defect were determined and the results were compared with RNI or AI value recommended by Chinese Nutrition Society.

It showed that the dietary pattern for subjects mainly consisted of grains and vegetables. Compared with Chinese DRIs, intakes of vegetables fruits, milk, meat and fish were not enough. In general, zinc and vitamin E intakes of each group have achieve the basic requirement. However, iron, selenium, copper, vitamin C, retinol, folic acid and vitamin B12 intakes were obviously inadequate.
