【摘要】：目的了解辽宁省某沿海城市孕妇碘营养现状及影响因素,为防治沿海地区孕妇人群碘营养异常提供分类指导理论参考,并为孕妇人群科学补碘提供有效的理论依据。方法采用整群抽样的方法,于2015年6月~2017年3月抽取在该市某三甲医院进行产前检查且现住址为该市三个不同县区居住十年以上的594名孕妇晨间尿样进行尿碘含量检测,并对孕妇基本情况、日食盐量、碘营养知识、一个月内日常饮食频率等因素进行问卷调查。以孕妇尿碘值为因变量,可能影响尿碘升高或降低的因素作为自变量进行非条件Logistic回归分析,筛选出影响孕妇尿碘的因素,并使用统计软件SPSS22.0对相关数据进行统计分析。结果1.本次调查的594例孕妇尿碘范围在11.3μg/L~1133.2μg/L之间,中位数为218.4μg/L,四分位数间距(P25~P75)为144.350μg/L~273.475μg/L;2.根据WHO/UNICEF/ICCIDD推荐的人群碘营养状况评价标准,本次检测尿碘含量的低碘构成比为26.76%,适碘构成比为39.23%,高碘构成比为34.01%;3.非条件Logistic回归分析结果显示,孕妇低碘的保护因素可为食用肉类、碘盐、乳制品、海产品、受教育程度高、碘营养知晓率得分高;孕妇低碘的危险因素是职业可为农民及食用小米。在本次调查中,食用小米是高碘的危险因素,而受教育程度高为孕妇高碘的保护因素。结论1.该沿海城市孕妇人群碘营养现状良好,通过孕妇人群尿碘检测显示碘营养处于适宜状态,符合WHO/UNICEF/ICCIDD规定的营养水平;2.孕妇低碘的保护因素是食用肉类、碘盐、乳制品、海产品、受教育程度高、碘营养知晓率得分高;孕妇低碘的危险因素是职业为农民及食用小米。在本次调查中,食用小米是高碘的危险因素,而受教育程度高及食用碘盐均为孕妇高碘的保护因素;3.妊娠期间作为碘元素摄入的敏感时期,应注意合理补碘,避免因摄入碘营养异常导致的不良影响。
[Abstract]:Objective to investigate the iodine nutrition status and influencing factors of pregnant women in a coastal city of Liaoning Province, and to provide a theoretical basis for the prevention and treatment of iodine deficiency among pregnant women in coastal areas, and to provide an effective theoretical basis for the scientific iodine supplementation of pregnant women. Methods from June 2015 to March 2017, 594 pregnant women whose current address is more than 10 years living in three different counties of the city were selected for prenatal examination from June 2015 to March 2017. The basic condition of pregnant women, the amount of daily salt, the knowledge of iodine nutrition, the frequency of daily diet and so on were investigated. Taking the urinary iodine value of pregnant women as dependent variable, the factors that may influence the increase or decrease of urinary iodine were used as independent variables to analyze the factors affecting the urinary iodine of pregnant women by non-conditional Logistic regression analysis. The statistical software SPSS22.0 was used to analyze the related data. Result 1. The urinary iodine range of 594 pregnant women was 11.3 渭 g/L~1133.2 渭 g / L with a median of 218.4 渭 g / L and a P25~P75 of 144.350 渭 g/L~273.475 渭 g / L 路L ~ (-1). According to the standard recommended by WHO/UNICEF/ICCIDD, the iodine composition ratio of urinary iodine content was 26.76%, the appropriate iodine composition ratio was 39.23, and the high iodine composition ratio was 34.01%. Non-conditional Logistic regression analysis showed that the protective factors of iodine deficiency in pregnant women were edible meat, iodized salt, dairy products, seafood, high education level and high awareness rate of iodine nutrition. The risk factor for pregnant women with iodine deficiency is that the occupation can be for farmers and edible millet. In this survey, millet consumption is a risk factor for iodine, and high level of education is a protective factor for pregnant women. Conclusion 1. The iodine nutrition status of pregnant women in this coastal city is good. The urine iodine test of pregnant women shows that iodine nutrition is in an appropriate state and conforms to the nutritional level specified by WHO/UNICEF/ICCIDD. The protective factors of iodine deficiency in pregnant women were consumption of meat, iodized salt, dairy products, seafood, high level of education, high awareness rate of iodine nutrition, and the risk factors of pregnant women's iodine deficiency were farmers and millet. In this survey, consumption of millet is a risk factor for high iodine, while high education and iodized salt are the protective factors of high iodine in pregnant women. As a sensitive period of iodine intake during pregnancy, attention should be paid to rational iodine supplementation to avoid adverse effects caused by abnormal iodine intake.
