【 摘 要 】

AbstractObjectiveTo identify children's iodine nutrition and goitre status in areas with mildly excessive iodine in drinking water.DesignA cross-sectional survey. Probability proportional to size sampling was employed to randomly select children from thirty townships where the median iodine content in drinking water ranged from 150 to 300 μg/l; their urinary iodine concentrations were determined and their thyroid volumes were measured by ultrasound. Drinking water samples and salt samples from the villages where the children lived were collected using a systematic sampling method.SettingHebei Province of China.SubjectsA total of 1259 children aged 8–10 years (621 boys and 638 girls).ResultsChildren's median urinary iodine concentration was found to be 418·8 μg/l, and the iodine concentration was >300 μg/l for 68·3 % (248/363) of the urine samples. Children's median urinary iodine concentration in villages with median salt iodine >10 mg/kg was significantly higher than that in villages with median salt iodine
