目的调查新疆乌鲁木齐市和克拉玛依市8~10岁学龄儿童的碘营养水平调查,分析这两个地区8~10岁学龄儿童碘营养水平的差异,为调整碘缺乏病防治措施提供科学依据。方法采用过硫酸铵消化砷—铈催化分光光度法对抽检的8~10岁学龄儿童进行尿碘检测,采用B超法检查儿童的甲状腺容积,同时测算儿童所在家庭人均每日碘盐摄入量,采用直接滴定法测定食盐中碘含量;采用Spss 17.0软件进行统计学分析。结果 1乌鲁木齐市和克拉玛依市学龄儿童家庭人均每日碘盐摄入量分别为6.38 g和6.09 g,乌鲁木齐市儿童家庭人均每日碘盐摄入量高于克拉玛依市,差异有统计学意义(t=2.63,P<0.05);碘盐覆盖率均为100.00%;碘盐合格率分别为99.40%和100.00%;乌鲁木齐市和克拉玛依市学龄儿童盐碘中位数分别为28.10 mg/kg和33.10 mg/kg,差异有统计学意义(Z=8.87,P<0.01);2乌鲁木齐市和克拉玛依市儿童尿碘中位数分别为196.40μg/L和167.00μg/L,乌鲁木齐市儿童尿碘水平高于克拉玛依市,差异有统计学意义(Z=3.81,P<0.01);3乌鲁木齐市儿童不同性别间尿碘水平差异无统计学意义(Z=1.37,P>0.05);克拉玛依市儿童不同性别间尿碘水平差异亦无统计学意义(Z=0.37,P>0.05);4乌鲁木齐市儿童不同年龄组尿碘水平差异无统计学意义(χ2=1.365,P>0.05);克拉玛依市儿童不同年龄组尿碘水平差异亦无统计学意义(χ2=0.319,P>0.05);5乌鲁木齐市儿童甲状腺肿大率为1.20%,克拉玛依市为零。结论乌鲁木齐市和克拉玛依市儿童碘营养水平总体处于适宜状态,有必要继续保持对学龄儿童碘营养水平的动态持续性监测,为政府制定政策提供依据。
Objective To investigate the iodine nutrition of school-age children aged 8 ~ 10 in Urumqi and Karamay in Xinjiang and to analyze the differences in iodine nutrition among school-aged children aged 8 ~ 10 in order to provide a scientific basis for adjusting the prevention and treatment of iodine deficiency disorders. Methods Arsenic-cerium catalytic spectrophotometry with ammonium persulfate digestion was used to detect urine iodine in children aged 8 to 10 years. The children’s thyroid volume was examined by B-mode ultrasonography, and daily iodized salt intake per capita was calculated , Using direct titration method to determine iodine content in salt; using the software of Spss 17.0 for statistical analysis. Results 1 The per capita daily iodized salt intake of school-age children in Urumqi and Karamay were 6.38 g and 6.09 g respectively, and the per capita daily iodized salt intake of children in Urumqi was significantly higher than that in Karamay (t = 2.63, P <0.05). The coverage rate of iodized salt was 100.00%. The qualified rate of iodized salt was 99.40% and 100.00% respectively. The median of iodized salt in school-age children in Urumqi and Karamay was 28.10 mg / kg and 33.10 mg respectively / kg, the difference was statistically significant (Z = 8.87, P <0.01) .2 Urinary iodine median of children in Urumqi and Karamay were196.40μg / L and167.00μg / L respectively, urinary iodine level was higher in Urumqi children (Z = 3.81, P <0.01) .3 There was no significant difference in urinary iodine levels among children of Urumchi (Z = 1.37, P> 0.05). There was no significant difference in urine among different sexes in Karamay There was no significant difference in the level of iodine between the two groups (Z = 0.37, P> 0.05) .4 There was no significant difference in urinary iodine level between Urumqi children in different age groups (χ2 = 1.365, P> 0.05) There was no significant difference in iodine levels (χ2 = 0.319, P> 0.05). 5 Urumqi Children goiter rate was 1.20%, Karamay zero. Conclusion The iodine nutrition of children in Urumqi and Karamay is generally in a suitable state. It is necessary to continue to maintain the dynamic continuous monitoring of iodine nutrition of school-age children and provide basis for the government to formulate policies.
