Abstract:
More than 90％ of the iodine intake by the human body is excreted in the urine. Therefore, the urinary iodine excretion is a good indicator for measuring recent iodine intake of the human body. During pregnancy, pregnant women are in a special physiological stage, the intake and discharge of iodine are significantly different from other stages and crowds. At present, the evaluation criteria for urinary iodine levels in pregnant women in China adopt the World Health Organization/United Nations International Children's Emergency Fund/International Committee for the Control of Iodine Deficiency (WHO/UNICEF/ICCIDD) recommendation: the median urinary iodine range is 150 - 249 μg/L. However, this standard is scheduled in 2007, 12 years ago, and due to differences in race, geography, diet, etc., whether the international standards are applicable to China's actual situation deserves further study. This article reviews the current research status of the optimal range of urinary iodine in pregnant women in China, and provides reference for future iodine nutrition monitoring of pregnant women.
