目的了解福建沿海产盐区与非产盐区哺乳期妇女碘营养状况及其甲状腺功能水平,为科学防治碘缺乏病提供依据。方法选择产盐区翔安区和非产盐区集美区为调查点,调查居民饮用水水碘含量,哺乳期妇女家中的碘盐覆盖率、合格碘盐食用率及其尿碘水平和血清甲状腺激素水平。结果产盐区、非产盐区哺乳期妇女家中合格碘盐食用率分别为91.18%和96.67%,尿碘中位数分别为131.20μg/L和104.35μg/L,尿碘<100μg/L的比例分别为35.29%和46.66%;产盐区与非产盐区哺乳期妇女的甲状腺激素TPOAb、TGA、TT3、TT4、FT3、FT4、TSH、Tg的中位数均在正常范围,两区均有部份哺乳期妇女存在甲状腺功能减退倾向,产盐区较非产盐区更为严重。结论目前的盐碘浓度对产盐区和非产盐区哺乳期妇女总体是适宜的,产盐区和非产盐区均有部分哺乳期妇女存在碘营养不足和甲状腺功能减退倾向。应对哺乳期妇女开展常规碘营养和甲状腺功能监测,采取针对性补碘措施,以控制碘缺乏病的发生。
Objective To understand iodine nutrition and thyroid function of breast-feeding women in coastal and non-salt-producing areas of Fujian Province, and to provide basis for scientific prevention and treatment of iodine deficiency. Methods The Xiangtan District of Salt Production and Jimei District of non-salt-producing areas were selected as the investigation points to investigate the iodine content of drinking water, the coverage of iodized salt, the intake of iodine salt, the level of urinary iodine and serum thyroid Hormone levels. Results The salt consumption rates of qualified iodized salt in the lactating women in the salt-producing and non-salt-producing areas were 91.18% and 96.67% respectively, the median urinary iodine were 131.20μg / L and 104.35μg / L respectively, urinary iodine <100μg / L The ratios of thyroid hormones TPOAb, TGA, TT3, TT4, FT3, FT4, TSH and Tg in breast-feeding women in salt-producing and non-salt-producing areas were all in the normal range, Some lactating women have the tendency of hypothyroidism, salt-producing areas more serious than non-salt-producing areas. Conclusions The present salt iodine concentration is suitable for lactating women in both salt-producing and non-salt-producing areas. Some lactating women in salt-producing areas and non-salt-producing areas have iodine deficiency and hypothyroidism tendency. To lactating women to carry out regular iodine nutrition and thyroid function monitoring, to take targeted iodine measures to control the occurrence of iodine deficiency disorders.
