The Survey Of Iodine Nutrition Condition Of Key Crowd In Urumqi And Karamay

Objective: To explore whether the dose of iodized salt, the measures of iodinesupplement are suitable for the school-aged children, the pregnant women and lactatingwomen in Urumqi and Karamay, in order to offer scientific basis for government andHealth sector and salt industry sector to take scientific and effective measures of iodinesupplement. Methods: Used cluster sampling, checked thyroid gland of each child byultrasound method, collected urine samples from the8～10years old school-agedchildren and iodized salts from their families in the same school in the two areasrespectively, estimated per capita daily salt intake of the family and quantitativelydetermined by direct titration of iodine (GB/T13025.7-1999); Collected the urine samplesof pregnant women and that of lactating women respectively in the street near the school,measured with arsenic-cerium catalyzed spectrophotometer technique. Used Epidata3.1to established database about per capita daily salt intake, salt iodine, urinary iodine andgoiter rate, Analyzed by SPSS17.0. Results:(1) The indicators had statistics differenceamong the levels of per capita daily salt intake, salt iodine in the families withschool-aged children and urinary iodine of the children in the two areas, per capita dailysalt intake of the children families in Urumqi was higher than that in Karamay (t=2.63,P=0.01), the salt iodine level of Urumqi was lower than that of Karamay (t=9.31, P＜0.001), the urinary iodine level of school-aged children in Urumqi was higher than that inKaramay (Z=3.81, P＜0.001).(2) There were no significant differences of urinary iodinelevels between different sex and age of the school-aged children (P＞0.05).(3) Thedifference of urinary iodine levels between the pregnant women in the two areas were notsignificant in statistic (Z=1.12, P=0.26), There were significant differences of urinaryiodine levels between the lactating women in the two areas(Z=4.41, P＜0.001), theurinary iodine level in Urumqi was higher than that in Karamay.(4) Goiter rate was1.2% in Urumqi and0in Karamay.(5) The average concentration of water iodine in Urumqiwas2.54μg/L and1.62μg/L in Karamay. Conclusion: The appropriate indexes of percapita daily salt intake, salt iodine and urinary iodine of the key crowd in Urumqi andKaramay reach national standards; suggest the iodized salt concentration and currentiodine measure are suitable for the key crowd in the two areas. The differences areexisted about the indicators of per capita daily salt intake, salt iodine and urinary iodineof school-aged children, and urinary iodine level of pregnant women in the two areas. Itshows that the iodine nutrition levels of key crowd should be kept on strengthened andnecessary, the investigation may provide the scientific basis for government policiesmaking.
