ABSTRACT
Objective To evaluate the iodine nutritional condition among populations in Aksu after implementing free iodized salt in population of Xinjiang.Methods According to the National Iodine Deficiency Monitoring Programme (Revised),totally 45 villages (towns) of subordinated 8 counties and Aksu City,Xinjiang were selected for collecting salt samples.Meanwhile,in 27 villages (towns) primary schools,school-aged children (8-10 years old) were selected for collecting disposable urine samples,B ultrasound was used to check thyroid volume and intelligence (IQ) was evaluated by China Combined Raven Test (CRT).Pregnant women were sampled for collecting their disposable urine near the primary schools.Both the children and pregnant women were evaluated the iodine deficiency disorders (IDD) knowledge awareness by questionnaire.The urine iodine concentration was measured by the ammonium persulfate digestion-As-Ce catalytic spectrophotometer method.The salt iodine concentration was measured by the direct titrimetric method,and other kinds of iodine in salt were measured by referee method (GB/T 13025.7-2012).Results A total of 2 700 household salt samples were collected,the average of iodine concentration in household salt was (26.95 ± 5.10) mg/kg.The coverage of household iodized salt was 98.56% (2 661/2 700).The coverage of edible iodized salt was 98.00% (2 646/2 700).A total of 2 159 urine samples were collected,the median of urine iodine concentration (UIC) among school-aged children (8-10 years old) was 235.50 μg/L.The total goiter rate was 1.51% (33/2 179) among children aged 8-10 years old.A total of 2 098 people were conducted IQ test,the average IQ was 88.03 ± 17.14.A total of 1 047 urine samples were collected,the median of UIC among pregnant women was 213.50 μg/L.The IDD knowledge awareness rate of children and women were 98.82% (751/760) and 99.23% (258/260),respectively.Conclusions The iodine nutrition is in an adequate range,awareness of IDD prevention is obviously improved among children which is representative of common people and pregnant women after implementing the free iodized salt in population of Xinjiang in Aksu.The policy of preventing IDD based on this policy has showed enormous effect.
