To investigate micronutrients intake of pregnant women in 8 cities.
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.
There were 479 pregnantwomen in analysis, 58. 9% of whom were 25. 1 to 30 years old and the number of pregnant women in every trimester was approximately equal, counting for 1/3 respectively. 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.
Of all the participants, nutritional status of pregnant women in Lanzhou was poorest compare with those in other cities and more attention should be paid on their dietary nutrition. Compared with result of 2002, nutrients intakes of pregnant women were improved in this survey.
调查8个城市孕妇的微量营养素摄入情况。
2011年9月至2012年3月，采用多阶段分层整群抽样方法，在8个城市（北京、上海、广州、兰州、沈阳、成都、郑州和苏州）招募健康孕妇，然后通过面对面调查收集一般信息和饮食状况。随后计算并分析营养素摄入量。
纳入分析的孕妇有479名，其中58.9%年龄在25.1至30岁之间，每个孕期的孕妇人数大致相等，各占三分之一。主成分分析显示，兰州的孕妇微量营养素状况最差。与其他7个城市的孕妇相比，兰州孕妇的核黄素、维生素C、维生素A、叶酸和钙的摄入量最低。郑州孕妇的大多数B族维生素摄入量最高，上海孕妇的维生素A、维生素C、钙摄入量分别最高。
在所有参与调查者中，兰州孕妇的营养状况与其他城市相比最差，应更加关注她们的饮食营养。与2002年的结果相比，本次调查中孕妇的营养素摄入量有所改善。
