摘　　要：目的 了解石家庄市城区和农村妊娠妇女碘营养状况.方法 2010、2011年,在石家庄市选择长安区的8个居委会,以长期居住的妊娠妇女（外来人口在此居住1年以上者）作为城区调查对象;另在石家庄市18个县72个村,以长期居住的农村户口的妊娠妇女作为农村调查对象.根据孕龄,将妊娠妇女划分为孕早期（≤12周）、孕中期（13～28周）、孕晚期（29 ～ 40周）.采集调查对象随意1次尿样,采用砷铈催化分光光度法（WS/T107-2006）检测尿碘.结果 共调查妊娠妇女1 635例,尿碘中位数为156.7 μg/L.其中城区737例、农村898例,尿碘中位数分别为169.0、145.9 μg/L,二者比较,差异有统计学意义（x2=54.569,P＜0.05）.尿碘＜150μg/L的城区妊娠妇女有297例（40.30％）,农村妊娠妇女有466例（51.89％）,二者比较,差异有统计学意义（x2=21.864,P＜ 0.05）.城区和农村妊娠妇女孕晚期尿碘中位数分别为113.5、145.6 μg/L,低于国家推荐标准（150μg/L）,且二者比较,差异有统计学意义（x2=8.365,P＜ 0.05）,但孕晚期尿碘＜150 μg/L的比例比较,差异无统计学意义[60.19％（65/108）比51.96％（93/179）,x2=1.844,P＞ 0.05].结论 石家庄地区妊娠妇女碘营养状况总体处于适宜水平,其中城区妊娠妇女碘营养处于适宜状态,而农村妊娠妇女处于轻度碘缺乏状态;无论是城区还是农村妊娠妇女孕晚期均处于碘缺乏状态,因此,对于妊娠妇女,特别是孕晚期,除了食用合格碘盐外,还应合理调整饮食结构,补充富含碘的食物,同时进行孕期全程动态监测,这对保持适宜碘营养水平具有十分重要的意义.Objective To understand the iodine nutritional status of urban and rural pregnant women in Shijiazhuang.Methods Urban pregnant women were selected from 8 neighborhood committees of Chang＇ an District,Shijiazhuang,while the rural pregnant women were selected from 72 villages of 18 counties in Shijiazhuang.These research subjects were grouped into women with early pregnancy at 1-12 weeks,mid pregnancy at 13-28 weeks and third trimester at 32-40 weeks.Urine samples of the subjects were collected.Arsenic-cerium catalytic spectrophotometry （WS/T 107-2006） was used to determine urinary iodine concentrations （UIC）.Results Seven hundred thirty-seven urban pregnant women and 898 cases from the rural areas,totally 1 635 subjects were included into the survey.The median UIC of urban subjects,rural cases,and all pregnant women in Shijiazhuang was 169.0,145.9 and 156.7 μg/L,respectively.The median UIC of the rural pregnant women was significantly lower than that of their urban peers （x2 =54.569,P 〈 0.05）.Urban pregnant women with UIC less than 150 μg/L accounted for 40.30% （297/737） of the total cases,and rural pregnant women 51.89% （466/898）.The difference was statistically significant between these subjects （x2 =21.864,P 〈 0.05）.The median UIC of pregnant women at third trimester of the urban and the rural areas was 113.5 and 145.6 μg/L,respectively.Though their UICs were not up to the national criteria （150 μg/L）,the difference was statistically significant between the urban and the rural subjects （x2 =8.365,P 〈 0.05）.UIC less than 150 μg/L of the urban and the rural pregnant women [60.19% （65/108） vs 51.96% （93/179）]at third trimester was not significantly different （x2 =1.844,P 〉 0.05）.Conclusions Iodine deficiency is present in pregnant women in Shijiazhuang City.Iodine deficiency among rural pregnant is more severe than that of peers of urban.The iodine deficiency is more severe in the pregnant population at late pregnancy.Besides iodized salt,food with rich io
