摘要
目的了解杭州市孕妇碘营养状况,并分析其影响因素,为指导杭州市孕妇科学补碘提供依据。方法采用分层随机抽样方法,于2018年3-10月对杭州市1400名孕妇进行问卷调查,采集孕妇随机尿样和家中食用盐盐样,分别采用砷铈催化分光光度法和直接滴定法检测尿碘、盐碘含量。分析不同基本特征、膳食水平的孕妇尿碘分布水平差异(Kruskal-Wallis检验)及尿碘水平主要影响因素(有序多分类logistic回归法)。结果孕妇尿碘中位数为135.00μg/L,合格碘盐食用率为83.36%(1167/1400)。基本特征方面,是否有孩子,怀孕次数、分娩次数、自然流产次数不同的孕妇尿碘分布水平比较,差异均有统计学意义(均P<0.05)。膳食方面,食用牛奶、酸奶、肉类频率不同的孕妇,以及是否食用卷心菜、白菜、菜花或绿花椰菜的孕妇尿碘分布水平比较,差异均有统计学意义(均P<0.05)。有序多分类logistic回归分析显示,怀孕2次的孕妇尿碘水平高于≥3次的孕妇(OR=1.64,P=0.003);从不或偶尔食用酸奶的孕妇尿碘水平低于≥2瓶/d的孕妇(OR=0.53,P=0.044);从不或偶尔和1次/周食用肉类的孕妇尿碘水平均高于≥2次/周的孕妇(OR=1.40、1.47,均P<0.05)。结论杭州市孕妇整体碘营养处于缺乏水平,妊娠经历和膳食水平是孕妇碘营养的影响因素。应深入开展针对孕妇的健康教育,完善孕期饮食结构,改善孕妇碘营养状况。
Objective To investigate the iodine nutritional status of pregnant women in Hangzhou City and analyze its influencing factors,in order to provide a basis for guiding pregnant women in Hangzhou City to supplement iodine scientifically.Methods A stratified random sampling method was used to conduct a questionnaire survey on 1400 pregnant women in Hangzhou City from March to October 2018.Random urine samples and household salt samples from pregnant women were collected,and the levels of urine iodine and salt iodine were measured using arsenic cerium catalytic spectrophotometry and direct titration,respectively.The iodine nutritional status of pregnant women with different basic characteristics and dietary levels were analyzed and compared(Kruskal-Wallis test),and the main influencing factors affecting the urinary iodine concentration level of pregnant women were identified(the ordinal multiple classification logistic regression analysis).Results The median urinary iodine of pregnant women was 135.00μg/L,and the qualified iodized salt consumption rate of pregnant women was 83.36%(1167/1400).In terms of basic characteristics,there were statistically significant differences in the distribution level of urine iodine among pregnant women with different pregnancy frequency,delivery frequency,and natural abortion frequency(P<0.05).In terms of diet,the frequency of consuming milk,yogurt,meat,and whether pregnant women consumed cabbage and cauliflower showed statistically significant differences in urinary iodine distribution levels(P<0.05).Ordinal multiple classification logistic regression analysis showed that the urine iodine levels of pregnant women who were pregnant twice were higher than those who were pregnant≥3 times(OR=1.64,P=0.003).Pregnant women who never or occasionally consumed yogurt had lower urine iodine levels than or equal to those who consumed 2 bottles of yogurt per day(OR=0.53,P=0.044).Pregnant women who never or occasionally consumed meat and those who consumed meat once a week had higher urinary iodine levels than that who consumed meat≥2 times per week(OR=1.40,1.47,P<0.05).Conclusions The overall iodine nutrition of pregnant women in Hangzhou City is at an deficiency level.Pregnancy experience and dietary level are influencing factors on iodine nutrition of pregnant women.It is necessary to carry out in-depth health education for pregnant women,improve the dietary structure during pregnancy,and improve the abnormal iodine nutrition of pregnant women.
