2007-2009年河北省沧州市碘缺乏病监测结果分析

目的 了解河北省沧州市碘缺乏病防治状况,为防治碘缺乏病提供科学依据.方法 2007-2009年,选择碘盐覆盖率较低的河间市、献县开展碘缺乏病动态监测.监测县(市)按东、西、南、北、中抽取9个乡(镇),每个乡(镇)抽取4个行政村,每个行政村抽检8户居民食用盐样,检测盐碘;每年采集1～3份居民饮用水样,测定水碘;每年抽取8～10岁小学生100名以上,检查甲状腺肿大情况并测定尿碘,选取40名以上学生测定其家中食盐含碘量;抽取50名以上18～40岁育龄妇女,测定尿碘.甲状腺检查采用触诊法;水碘和尿碘检测采用砷铈催化分光光度法;盐碘检测采用直接滴定法.结果 2007-2009年河问市、献县居民户盐碘中位数分别为4.3、15.9,3.6、18.4,4.6、11.7 mg/kg,碘盐覆盖率分别为34.03%(98/288)、78.82%(227/288),29.86%(86/288)、84.72%(244/288)和37.15%(107/288)、49.31%(142/288),合格碘盐食用率分别为27.08%(78/288)、36.46%(105/288),28.13%(81/288)、49.31%(142/288)和37.15%(107/288)、30.90%(89/288).检测饮用水10份,水碘为5.5～34.4μg/L.2007-2009年8～10岁小学生甲状腺肿大率均＜5%,尿碘中位数分别为138.1、176.6、112.0 μg/L,＜100 μg/L的比率分别为31.6%(65/206)、25.0%(52/208)和44.4%(91/205);育龄妇女尿碘中位数分别为167.3、164.2、78.1μg/L,＜100 μg/L的比率分别为28.7%(29/101)、19.2%(20/104)和60.0%(60/100).结论 在碘盐覆盖率较低的地区,人群碘营养水平受到影响,育龄妇女出现碘营养不足.

Abstract：

Objective To understand the situation of iodine deficiency disorders of Cangzhou city, Hebei province, in order to provide the scientific basis for prevention and control of iodine deficiency disorders. Methods From 2007 to 2009, dynamic monitoring of iodine deficiency disorders was carried out in low iodized salt coverage places Hejian city and Xian county. Nine towns were randomly chosen in each county, 4 administrative villages were randomly selected in each town, 8 household salts were tested in each village. Every year, 1 - 3 copies of residents water samples were collected for determination of iodine; more than 100 students age 8 - 10 years old were checked the situation of goiter and urinary iodine, more than 40 students selected were measured iodine content of salt from their home; more than 50 women of childbearing age 18 - 40 years were tested of urinary iodine. Thyroid was examined with palpation; water iodine and urine iodine concentration were measured with arsenic-Ce catalytic spectrophotometry; salt iodine was detected by direct titration. Results From 2007 to 2009,median household salt iodine were 4.3,15.9,3.6,18.4,4.6,11.7 mg/kg in Hejian city and Xian county, respectively,iodized salt accounted for 34.03% (98/288), 78.82% (227/288), 29.86% (86/288), 84.72% (244/288), 37.15%(107/288),49.31% (142/288), respectively, the consuming rate of iodized salt were 27.08% (78/288),36.46%( 105/288 ), 28.13% (81/288 ), 49.31% ( 142/288 ), 37.15 % ( 107/288 ), 30.90% ( 89/288 ), respectively. Ten samples of drinking water were tested, water iodine were 5.5 - 34.4 μg/L. From 2007 to 2009, the goiter rate of students aged 8 - 10 years old was below 5%, the median of urinary iodine were 138.1,176.6,112.0 μg/L, ＜ 100 μg/L ratio were 31.6% ( 65/206 ), 25.0% ( 52/208 ) and 44.4% (91/205 ). The median of urinary iodine of child-bearing age women were 167.3,164.2,78.1 μg/L, ＜ 100 μg/L ratio were 28.7%(29/101 ), 19.2%(20/104) and 60.0%(60/100).Conclusions In areas with low coverage of iodized salt, iodine nutrition level are affected, the child-bearing age
