Objective To investigate the current status of iodine deficiency disorders (IDD) in Inner Mongolia Autonomous Region,residents iodine nutrition level and preventive measures being implemented,so as to master the background status of residents iodine nutrition before introduction of new concentration standards of iodized salt in the autonomous region; and to evaluate the effect of interventions implemented.Methods According to stratified sampling with probability proportional to size (PPS),a sample of 30 units was extracted,and then a primary school was extracted from each sampling unit.From each primary school 40 students aged 8-10(male and female half and half) were checked thyroid volume though B-ultrasonic and iodine content of edible salt in these students' homes was quantitatively determined.Around the primary school,3 villages were randomly selected,and then 5 pregnant and 5 lactating women were selected.Urinary iodine was measured by ammonium persulfate digestion-arsenic cerium catalysis spectrophotometry.Children urinary iodine level monitoring:In each county (city,district,flag) 1 village(town,district office) was randomly selected according to its sub-area positions in the north,the south,the east,the west and the center of the county; and then a village primary school(in the absence of village primary school,township central primary school was selected) was selected; from each school 20 children aged 8-10 were selected.A total of 100 urine samples were tested in each county.Results Goiter rate of children aged 8-10 was 3.1％(37/1206); median urinary iodine level(UI) was 259.9 μg/L; the median of residents consumption of iodized salt was 30.2 mg/kg; the coverage rate of iodized salt was 99.3％(1194/1203);the consumption rate of iodized salt was 98.1％ (1184/1203); the qualified rate of iodized salt was 98.8％ (1180/1194); the rate of non-iodized salt was 0.7％ (8/1203) and failure rate was 1.2％(15/1203).The number of urine sample was 6993 ; the median urinary iodine was 249.0 μg/L in children age 8-10,and UI level lower than 50.0 μg/L accounted for 1.50％ (105/1993).Conclusions After salt iodization as main comprehensive measures in prevention and control of iodine deficiency disorders,remarkable progress has been made in Inner Mongolia.The coverage rate of iodized salt,the consumption of iodized salt,goiter rate,and UI median all have reached the standard of elimination of iodine deficiency disorders.Children iodine nutrition level is in enough state,pregnant and lactating women iodine nutrition level is in suitable condition.
