ABSTRACT
Objective To analyze the monitoring data of iodine deficiency disorders in Jiangxi Province and to provide a basis for adjusting iodized salt concentration.Methods Thirty primary schools were selected in 30 counties and 40 pupils' goiters were examined with B ultrasound in every school.At the same time,salt iodine level was tested at their home.Twelve pupils urinary iodine in selected schools,15 pregnant urinary samples,15 lactating women urinary samples in 3 towns around the schools and water samples in the counties with the schools were collected.Results The goiter rate of children aged 8 to 10 was 1.25％ (15/1 200); the median salt iodine was 30.80 mg/kg and the consumption rate of qualified iodized salt was 96.92％ ; the median urinary iodine level of children,pregnant and lactating women was 308.73,206.95 and 206.75 μg/L,respectively.The proportion of urinary iodine level of children above 300 μg/L was 52.25％(186/356),while the proportion of urinary iodine level of pregnant women below 150 μg/L was 34.81％(157/451).The water iodine median was 4.62 μg/L and the per capita daily salt intake was 13.20 g in Jiangxi Province.Conclusions The status of iodine deficiency in Jiangxi has been significantly improved.According to the monitoring results,it's necessary to adjust salt iodization standards appropriately.
