Investigation on urinary iodine content of pregnant women and non-pregnant women of childbearing age in yingcheng

目的调查并研究应城市不同孕期妊娠妇女及育龄非妊娠妇女尿碘含量。方法前瞻性选取650例应城市人民医院产科门诊就诊并建立围产保健档案的妊娠妇女,另选取同期500例本院健康体检中心建档的正常育龄非妊娠妇女。统计分析两类妇女的尿碘水平,并统计分析妊娠妇女的尿碘情况。结果孕早期、孕中期、孕晚期妊娠妇女的尿碘水平低于非妊娠妇女,孕早期妊娠妇女的尿碘水平高于孕中期妊娠妇女(P<0.05),低于孕晚期妊娠妇女(P<0.05)。妊娠妇女650例中,碘缺乏142例,碘适量184例,碘超量209例,碘过量115例,分别占21.85%、28.31%、32.15%、17.69%。其中孕早期妊娠妇女的碘缺乏率低于孕中期、孕晚期妊娠妇女(P<0.05),碘过量率高于孕中期、孕晚期妊娠妇女(P<0.05),但孕中期、孕晚期妊娠妇女的碘缺乏率、碘过量率比较,差异无统计学意义(P>0.05);孕早期、孕中期妊娠妇女的碘适量率均低于孕晚期妊娠妇女(P<0.05),碘超量率均高于孕晚期妊娠妇女(P<0.05),但孕早期、孕中期妊娠妇女的碘适量率、碘超量率比较,差异无统计学意义(P>0.05)。结论应城市不同孕期妊娠妇女的尿碘含量低于育龄非妊娠妇女。

Objective To investigate the urinary iodine content of pregnant women and non-pregnant women of childbearing age in Yingcheng.Methods A total of 650 pregnant women who attended the obstetric clinic of City People's Hospital and established perinatal health care records were prospectively selected,and 500 non-pregnant women of normal childbearing age who were registered in the health examination center of our hospital during the same period were selected.The urine iodine levels of the two groups of women were analyzed statistically,and the urine iodine of pregnant women was analyzed statistically.Results The urinary iodine level of women in the first,second and third trimesters was lower than that of non-pregnant women,and the urinary iodine level of women in the first trimester was higher than that of women in the second trimester(P<0.05),but lower than that of women in the third trimester(P<0.05).Among 650 pregnant women,there were 142 cases of iodine deficiency,184 cases of iodine appropriate,209 cases of iodine excess and 115 cases of iodine excess,accounting for 21.85%,28.31%,32.15%and 17.69%respectively.The iodine deficiency rate of women in the first trimester was lower than that of women in the second and third trimesters(P<0.05),and the iodine excess rate was higher than that of women in the second and third trimesters(P<0.05),but there was no statistically significant difference between the iodine deficiency rate and iodine excess rate of women in the second and third trimesters(P>0.05).The iodine moderation rate of women in the first and second trimesters was lower than that of women in the third trimester(P<0.05),and the iodine excess rate was higher than that of women in the third trimester(P<0.05),but there was no statistical significance in the iodine moderation rate and iodine excess rate of women in the first and second trimesters(P>0.05).Conclusion The urinary iodine content of pregnant women at different pregnancy stages in Ying city is lower than that of non-pregnant women of childbearing age.
