[Micronutrients intake of pregnant women from 8 cities of China during 2011 to 2012].

OBJECTIVE

To investigate micronutrients intake of pregnant women in 8 cities.

METHODS

The multi-stage stratified cluster sampling method was applied in 8 cities( Beijing, Shanghai, Guangzhou, Lanzhou, Shenyang, Chengdu, Zhengzhou and Suzhou) from September 2011 to March 2012 to recruit healthy pregnant women, and then general information and dietary status were collected through face to face investigation. Nutrients intakes were calculated and analyzed then.

RESULTS

Principal components analysis showed pregnant women in Lanzhou share poorest status of micronutrients. For pregnant women in Lanzhou, intakes of riboflavin, vitamin C, vitamin A, folacin and calcium were lowest compared with pregnant women from other 7 cities. The most B-vitamins intakes of pregnant women in Zhengzhou, and vitamin A, vitamin C, calcium intake of pregnant women in Shanghai were highest, respectively.
