摘　　要：目的了解浙江省沿海与内陆地区孕妇及哺乳期妇女碘营养状况，为指导浙江省孕妇、哺乳期妇女科学补碘提供依据。方法2009年，采用整群抽样法在浙江省抽取13个县（区）作为调查点，其中沿海城市、沿海农村调查点各5个，内陆地区调查点3个。每个调查点抽取1街道（乡、镇），每个街道（乡、镇）中抽取1个居委会（行政村），每个居委会（村）中选择30名孕妇、30名哺乳期妇女、50名8—10岁学龄儿童，采集日间即时尿样检测尿碘；抽取30户家中食用盐盐样进行盐碘测定，同时采集饮用水水样进行水碘测定。水源数多于5个时，按东、西、南、北、中5个方位各随机采取一份水样；水源数少于5个时，采样份数同调查点水源数。结果沿海城市、沿海农村、内陆地区抽样家庭的碘盐中位数分别为28．42、25．29、33．24mg／kg，水碘中位数分别为5．41、11．52、2．80μg／L。孕妇和哺乳期妇女尿碘中位数分别为148．72、161．34μg／L，均低于当地8—10岁学龄儿童的231．02μg／L（Z值分别为8．57、8．24，P均〈0．017）；各地区中，内陆地区孕妇尿碘中位数最高为211．42μg／L，沿海农村次之为150．51μg／L，沿海城市最低为123．33μg／L（Z值分别为2．80、5．31、2．42，P均〈0．017），而内陆地区孕妇尿碘中位数（197．43μg／L）高于沿海城市（139．64μg／L，Z=4．03，P〈0．017）。结论浙江省哺乳期妇女碘营养水平总体处于适宜水平，沿海农村、内陆地区的孕妇碘营养也处于适宜水平，但沿海城市孕妇则在一定程度上存在碘营养水平不足的问题。Objective To evaluate the nutritional status of iodine of pregnant and lactating women in coastal and inland areas of Zhejiang province, and to provide scientific basis for iodine supplementation. Methods In 2009, five coastal cities, five coastal counties and three inland areas from Zhejiang province were selected by the cluster sampling method, and one sub-district（township） was randomly selected in each city （county）, then one community（village） was randomly selected in each sub-district （township）. Thirty pregnant women, thirty lactating women and fifty children aged 8 - 10, were randomly selected in each community（village） as the investigation objects to collect instant urine samples to detect urine iodine, and to collect thirty resident edible salt and some water samples to detect salt iodine and water iodine, if the numbers of water source were more than 5 then 1 water sample was collected by their location of east, south, west, north and center in each community（village）, otherwise, the numbers of water samples collected were equal to the number of community （village）. Results The medians of salt iodine of coastal city, coastal county and inland area were 28.42, 25.29, and 33.24 mg/kg, respectively, and the medians of water iodine correspondingly were 5.41, 11.52, and 2.80 μg/L, respectively. The medians of urinary iodine of pregnant and lactating women in Zhejiang province were 148.72 and 161.34μg/L, respectively,which were less than that of children aged 8 - 10（231.02μg/L, Z = 8.57,8.24, all P 〈 0.017）. The medians of urinary iodine in pregnant women from different areas were ranked in order as inland areas（211.42 μg/L）, coastal counties （150.51 μg/L） and coastal cities （123.33 μg/L, Z = 2.80, 5.31, 2.42, all P 〈 0.017）, and in lactating women, the medians of urinary iodine in inland areas（ 197.43 μg/L） was higher than that in coastal cities（ 139.64 μg/L,Z = 4.03, P 〈 0.017）. Conclusions The overall levels of iodine nutrition in lactating
