目的探讨流动人口孕妇膳食结构现状,为流动人口孕妇营养保健工作提供科学依据。方法对2006年1月~12月175例成都市北站地区流动人口孕妇的孕期膳食进行调查,并与同期住院分娩的189例城市居民孕妇进行对照分析。结果(1)两组孕妇孕期蔬菜的摄入均为经常性的(100.00%),差别无统计学意义(P>0.05)。(2)两组粗粮的摄入量均显不足(u=0.6993,P=0.4844)。(3)鱼、肉、奶类,鸡蛋、水果、粗粮的摄入情况,两组差别显著(P<0.05),流动人口组各类营养的摄入量不足。结论流动人口孕妇的孕期膳食结构存在诸多问题,应重点加强对其膳食合理性的指导,提高营养认知水平,保证胎儿正常发育及孕妇的健康。 Objective To study the status quo of pregnant women’s diet in floating population and provide scientific basis for nutrition and health care for pregnant women in floating population. Methods A total of 175 pregnant women with migrant workers in North Station of Chengdu from January 2006 to December 2006 were surveyed and compared with 189 pregnant women in urban areas during the same period of hospitalization. Results (1) Pregnancy intake of pregnant women in both groups were both regular (100.00%), with no significant difference (P> 0.05). (2) The intakes of coarse grains in both groups were not enough (u = 0.6993, P = 0.4844). (3) The intake of fish, meat, milk, eggs, fruits and whole grains was significantly different between the two groups (P <0.05). The intake of all kinds of nutrition in the floating population was not enough. Conclusion There are many problems in the dietary structure of pregnant women during the period of floating population. Emphasis should be laid on strengthening the guidance of dietary rationality, raising the cognitive level of nutrition, and ensuring the normal development of fetus and the health of pregnant women.
