目的了解宁夏5类人群(新婚妇女、孕妇、哺乳期妇女、0～2岁婴幼儿和8～10岁学生)的碘营养水平,为采取防治策略和措施提供依据.方法 2008、2009年,在全区22个县中,所辖有9个以上乡的县,按东、西、南、北、中5个方位采用整群随机抽样法抽取9个乡,每个乡抽取4个村,每个村采集4名特需人群和2名婴幼儿尿样;辖有9个或不足9个乡的县,按东、西、南、北、中划分5个方位各抽取1个乡,每个乡抽取4个行政村,每村采集8名特需人群和3名婴幼儿尿样.在22个县按东、西、南、北、中5个方位各抽取1个乡,每个乡各抽取1所村小学,每所小学采集20名8～10岁学生的尿样.尿碘采用砷铈催化分光光度法检测.结果共检测新婚妇女、孕妇、哺乳期妇女、0～2岁婴幼儿和8～10岁学生这5类人群的尿碘6894份,尿碘中位数分别为209.3、187.4、184.0、216.5、216.3μg/L,由低到高依次为哺乳期妇女＜孕妇＜新婚妇女＜学生＜婴幼儿,其中婴幼儿、孕妇和哺乳期妇女处于适宜水平,新婚妇女和学生高于适宜量.5类人群尿碘＜100 μg/L的比例分别为11.1%(53/475)、35.4%(308/871)、35.4%(659/1863)、19.1%(283/1483)、8.4%(185/2202),即孕妇和哺乳期妇女相对较高.各县5类人群的尿碘中位数差别也很大.结论宁夏5类人群尿碘存在明显的人群和地区差别.现行的食盐加碘量足以保证宁夏5类人群的碘营养需求,但新婚妇女及学生的碘营养水平有偏高的趋势,说明宁夏居民的盐含碘量有下调的空间,下调时要充分考虑人群和地区差别.

Objective To investigate the iodine nutritional level of 5 special groups (newly married women,pregnant women, lactating women, babies and infants, and students) in Ningxia, and to provide the basis for formulating prevention and control strategies. Methods Clustering and random sampling method were used. In 2008 and 2009, in the 22 counties investigated, in every county with 9 townships or more, nine townships were randomly selected according to their sub-area positions of east, west, south, north and center; four villages were randomly selected in each chosen township, four people with special needs and 2 infants were randomly selected for urine samples collection in each chosen village. In every county with 9 or less townships, one township was randomly selected respectively in east, west, south, north and center sub-areas; four villages were randomly sampled in each chosen township, eight people with special needs and 3 infants' urine samples were randomly collected in each chosen village. In the 22 counties, one township was randomly selected respectively in east, west,south, north and center sub-areas, one village elementary school was randomly sampled in each chosen township,twenty students aged 8 - 10 were randomly selected to collect their urine samples in each school. The iodine concentration was determined by arsenic-cerium contact method. Results A total of 6894 copied of urine samples from newly married women, pregnant women, lactating women, babies and infants, and students were examined, the urinary iodine medians were 209.3, 187.4, 184.0, 216.5, 216.3 μg/L, respectively. From low to high in the order was lactating women, pregnant women, newly married women, students, babies and infants. The level of urinary iodine of babies and infants, pregnant women and lactating women were appropriate, the one of newly married women and students were higher than appropriate. The proportion of less than 100 μg/L of urinary iodine of the 5 kinds special groups were 11.1% (53/475), 35.4% (308/871), 35.4% (659/1863), 19.1% (283/1483), 8.4%(185/2202), respectively, while the urinary iodine of the pregnant women and lactating women were relatively high. The urinary iodine medians of the 5 special groups were also very different among counties. Conclusions The urinary iodine of the 5 special groups in Ningxia presents obvious differences between populations and regions.Current iodized salt is sufficient to ensure iodine nutrition needs for the 5 special groups. But married women and students have higher levels of iodine nutrition, indicating that the salt iodine concentration of Ningxia residents have cut space, full consideration of the 5 special groups and regional differences should be taken.
