湖北地区孕妇碘营养状况及尿碘含量的影响因素分析

Survey on the pregnant women’s iodine intake and its influence factors of urine iodine concentrations in Hubei province

目的研究湖北地区孕妇碘营养状况及对孕妇尿碘含量的影响因素。方法采用整群分层抽样法进行抽样调查,抽取2015年10月-2017年10月湖北地区568例孕妇作为研究对象,收集研究对象的一般资料,观察孕妇碘营养状况。对比尿碘含量正常和尿碘含量异常对象的一般资料,对差异情况采用Logistic回归分析,分析孕妇尿碘含量的影响因素。结果研究对象中碘营养状况正常的孕妇258例,占45.42%;碘营养状况异常的孕妇310例,占54.58%。尿碘含量正常和尿碘含量异常的研究对象在文化程度、食盐量、海产品饮食频次、乳制品饮食频次、小米饮食频次、肉类饮食频次及碘剂补充情况方面比较,差异有统计学意义(P<0.05)。Logistic回归分析发现,文化程度、食盐量、海产品饮食频次、乳制品饮食频次、小米饮食频次、肉类饮食频次及碘剂补充情况是孕妇尿碘含量的影响因素(P<0.05)。结论湖北地区部分孕妇存在碘营养异常情况,应根据孕妇自身情况采取针对性干预,改善孕妇碘营养异常情况。

Objective To explore the pregnant women’s iodine intake and its influence factors of urine iodine concentrations in Hubei province.Methods Through the stratified cluster sampling method,568 pregnant women of being reviewed the iodine intake from October 2015 to October 2017 were chosen.According to the Logistic regression equation,the influence factors of urine iodine concentrations were analyzed.Results There were 258 pregnant women with normal iodine intake(45.42%)and 310 pregnant women with abnormal iodine intake(54.58%).The education background,salt intake,frequency of eating the marine products,drinking the dairy products,eating the millet and meats and iodine preparation supplements for patients with normal and abnormal urine iodine intake were significantly different(P<0.05);according to the Logistic regression equation,it was seen that the education background,salt intake,frequency of eating the marine products,drinking the dairy products,eating the millet and meats and iodine preparation supplements were the influence factors of the pregnant women’s urine iodine concentrations.Conclusion In Hubei province,some pregnant women may have the abnormal iodine intake.According to their actual conditions,the proper interventions are good to ameliorate the abnormalities of iodine intake.
