| Objective The southern XinJiang where is a traditional IDD high-risk area.To explore whether the current edible salt iodine supplement measures are appropriate for the school-aged children,the pregnant women and lactating women in HeTien and Akesu,in order to offer scientific basis for government and the relevant units to take scientific and effective measures of iodine supplement.Methods On the base of the national about IDD epidemiological investigation and national about IDD high-risk areas investigation,as the provinces to unit,according to the ‘population proportion sampling method',extracted HeTien,Karakax,Qira,and Keriya county in HeTien region,Shaya,Kuqa,WenSu and WuShi county in Akesu region.Adopt random sampling method to select a town and a school from each county,to select fifty from the 8~10 years old school-aged children that checked thyroid gland of each child by ultrasound method and collect iodized salts from their families in the same school in the each county.Collected fifty pregnant women and that of lactating women respectively in the street near the school(thirty women in 2011).Quantitatively determined by direct titration of iodine(GB/T13025.7-1999),measured with arsenic-cerium catalyzed spectrophotometer technique.Used Epidata3.1 to established database about salt iodine,urinary iodine and goiter rate,Analyzed by SPSS17.0.Results 1.The average concentration of water iodine in Akesu was 2.93?g/L and3.34?g/L in HeTien,there were no differences between two areas in wate iodine(T=7827.50,P=0.05).2.1 The average concentration of salt iodine in Akesu was 28.90 mg/kg and 26.35 mg/kg in HeTien,there were significant differences between two areas in iodine salt(T=157561.50,P<0.01),2.2 The average concentration of salt iodine in 2011 was 30.00 mg/kg and it was 25.61 mg/kg in 2014,there were significant differences in two years.3.1 The average of urinary iodine in school-aged children in 2011 was 213.40?g/L and 174.21?g/L in 2014,there were significant differences in two years(T=164076.5 P<0.001).3.2 The average of urinary iodine in Akesu was 249.55?g/L and was 157.83?g/L in HeTien that had significant differences in statistically.3.3 There were 411 women and the average of urinary iodine were 181.93?g/L,with 367 men and the average of urinary iodine were 200.01?g/L,there was a significant difference in male and female compared with urinary iodine frequency(T=151506.5,P<0.01).3.4 The average of urinary iodine in 8,9 and 10 years old were 165.15?g/L,196.04?g/L,217.06?g/L,the urinary iodine level in different ages had significant difference(T=23.52,P<0.01).4.1The average of urinary iodine in women of child-bearing age were 192.90?g/L,168.87?g/L in 2011 and 2014,there was a significant(T=158391,P<0.01);4.2 The average of urinary iodine in women of child-bearing age were 260.50?g/L in Akesu and were 145.60?g/L in HeTien,there were significant differences(T=148256,P<0.01);4.3 The urinary iodine in different ages,and the average were 182.53?g/L,184.91?g/L,208.48?g/L in 15~25,25~35 and up to 35 years old,there were no significant differences(2=1.90,P=0.05).5.1 Checked 310 children in Akesu the goiter rate was 3,23%,and 460 children in HeTien the goiter was 3,91%,the children goiter rates from different areas,gender ages had no statistical difference(=0.25,P=0.05,).5.2 Checked 320 children in 2011,the goiter number was 22 and goiter rate was 6.88%,that checked 450 in 2014 the goiter number 6 and goiter rate was 1.33%,children goiter rate had significant differences in two years(=16.39,P<0.01).6.The children's family salt iodine had no correlation with urinary iodine in 2011(r=0.08,P=0.43)and the children's family salt iodine had negative correlation with urinary iodine in 2014(r=-2.04,P=0.00).Conclusion The urinary iodine salt iodine of 8~10 years old school-aged and women of childbearing age in Akesu and HeTien meet the national and the Xinjiang IDD elimination and control standards,the survey suggest that current iodized salt consumption and fill iodine intervention strategies and for prevention and control the Xinjiang traditional IDD high-risk region is feasible.But it is also remind that rely on prompting iodized salt and eat iodine oil pill to prevention and control iodine deficiency disorders,it is necessary to preserve focusing on and intervention all people and highrisk region for a long time,except to strengthen the active monitoring and adjust timely and need many department operate that can achieve ideal control target. |
