目的 了解供应合格碘盐浓度下 ,新疆重点人群的碘营养状况。方法 对乌鲁木齐市和呼图壁县区域内的重点人群进行一次性调查。结果 城市重点人群的尿碘平均水平 (188.7μg/ L)略高于农村人群 (185 .4μg/ L) ,但差异无显著意义 (P >0 .0 5 )。城市组由高到低依次为 0～ 2岁婴幼儿、8～ 10岁儿童、哺乳期妇女、育龄妇女、孕妇 ;农村组由高到低依次为 0～ 2岁婴幼儿、孕妇、哺乳期妇女、育龄妇女、8～ 10岁儿童。城市组两两比较 ,8～ 10岁儿童与育龄妇女 ,育龄妇女与哺期乳妇女、0～ 2岁婴幼儿 ,孕妇与哺乳期妇女、0～ 2岁婴幼儿间差异均有显著意义 (P <0 .0 5或 P <0 .0 1) ;农村组两两比较 ,8～ 10岁儿童与孕妇、哺乳期妇女、0～ 2岁婴幼儿 ,育龄妇女与孕妇、0～ 2岁婴幼儿 ,哺乳期妇女与 0～ 2岁婴幼儿间差异均有显著意义 (P <0 .0 5或 P <0 .0 1)。结论 新疆重点人群在食用现行标准碘盐下均达到了适宜的碘营养水平 ,建议应维持现行碘盐浓度 (35± 15 ) m g/ kg。
Objective To understand the iodine nutrition status of key populations in Xinjiang under the supply of qualified iodized salt concentration. Methods One-time investigation of key population in Urumchi and Hutubi county regions was conducted. Results The average level of urinary iodine (188.7 μg / L) in urban key population was slightly higher than that of rural population (185.4 μg / L), but the difference was not significant (P> 0.05). The urban groups from high to low were 0 ~ 2 years old infants, 8 ~ 10 years old children, lactating women, women of childbearing age, pregnant women; rural areas from high to low were 0 to 2 years old infants, pregnant women, lactating women , Women of childbearing age, children aged 8 to 10 years old. In the urban group, the differences between the children aged 8-10 years and the women of childbearing age, the women of childbearing age and breast-feeding, the children of 0-2 years old, the pregnant and lactating women, the age of 0 ~ 2years old were significantly different (P <0. 0 5 or P <0. 01). In rural areas, children aged between 8 and 10 and pregnant women, lactating women, infants aged 0 ~ 2 years, women of childbearing age and pregnant women, children aged 0 ~ 2 years , Breast-feeding women and 0 to 2 years old infants between the differences were significant (P <0. 05 or P <0. Conclusion The key population in Xinjiang reached the appropriate level of iodine nutrition under the current standard iodized salt. It is suggested that the current iodized salt concentration should be maintained at 35 ± 15 m g / kg.
