Investigation of iodine nutrition in pregnant women in Dongguan City and analysis of its influencing factors

目的分析探讨东莞市孕妇碘营养状况调查及其影响因素。方法选取研究期间2012年9月-2016年1月在东莞市南城和康华医院妇产科收治的900例孕妇,由专业调查员收集患者一般资料,并采集其清晨尿样测定盐碘水平。运用Logstic多因素分析方法,获得孕妇高碘营养状况的影响因素。结果东莞市城区、郊区和农村孕妇的低尿碘水平占比、适宜尿碘水平占比、高尿碘水平占比均具有统计学意义(P<0.05)。单因素分析结果显示,受教育程度、劳动强度、食用海产品、食用肉蛋类、碘营养知晓情况是东莞地区孕妇碘营养状况的影响因素(P<0.05)。经多因素Logstic分析显示,受教育程度高是高碘营养状况的保护因素,重体力劳动强度和进程食用海产品是高碘营养状况的危险因素。结论东莞市孕妇碘营养总体水平不良,46.65%的孕妇处于碘营养不足状态。受教育程度高是高碘营养状况的保护因素,重体力劳动强度和食用海产品是高碘营养状况的危险因素。

Objective To investigate and analyze the iodine nutrition status of pregnant women in Dongguan and its influencing factors. Methods A total of 900 pregnant women who were admitted to Nanfang and Honghua Hospital Obstetrics and Gynecology during the study period from September 2012 to January 2016 were selected. The professional investigators collected the general information of patients and collected the early morning urine samples to determine the level of salt and iodine. And,the Logstic multivariate analysis was used to obtain the influencing factors of iodine nutrition status in pregnant women. Results The proportion of low urinary iodine,normal urinary iodine and high urinary iodine of pregnant women in urban area,suburban area and rural areas in Dongguan had statistically significant differences（ P 〈0. 05）. The results of univariate analysis showed that the educational level,labor intensity,consumption of seafood,meat and eggs,and awareness of iodine nutrition were the influencing factors of iodine nutrition status among pregnant women in Dongguan（ P 〈0. 05）. The multivariate Logistic analysis showed that high education level was the protective factor of high iodine nutritional status,and heavy physical labor intensity and regularly eating seafood were the risk factors of high iodine nutritional status. Conclusion The overall level of iodine nutrition in pregnant women in Dongguan is poor. 46. 65%pregnant women are in iodine deficiency state. Higher education is the protective factor of iodine nutrition,heavy physical labor intensity and eating seafood are the risk factors of high iodine nutritional status.
