2008年河南省三门峡市碘缺乏病调查结果分析

目的 了解河南省三门峡市碘缺乏病发展动态及防治效果,制订有针对性的碘缺乏病防治对策.方法 2008年,在三门峡市所属的灵宝市、陕县、湖滨区、义马市、渑池县、卢氏县6个县(市、区),每个县(市、区)按东、西、南、北、中5个方位抽取5个乡(镇、办事处),每个乡(镇、办事处)抽取1所小学,每所小学抽取8～10岁学生50名检查甲状腺,并采集其尿样和家庭食用盐样测定尿碘及盐碘.每所小学抽取30名5年级学生进行碘缺乏病知识健康教育问卷调查,在小学所在村按东、西、南、北、中不同方位采集饮用水5份进行水碘检测,并对10名家庭主妇进行碘缺乏病知识健康教育问卷调查.甲状腺检查采用触诊法;尿碘测定采用过硫酸铵消化-砷铈催化分光光度法(WS/T 107-2006);盐碘测定采用直接滴定法(GB/T 13025-1999);水碘测定采用砷铈催化分光光度法(GB/T 5750.5-2006).结果 6个县(市、区)共检查8～10岁儿童1500名,甲状腺肿大率为3.30%(50/1500),尿碘中位数为273.15μg/L;共检测盐样1500份,碘盐覆盖率为99.93%(1499/1500),碘盐合格率为98.00%(1469/1499),合格碘盐食用率为97.93%(1469/1500),非碘盐率为0.07%(1/1500),盐碘中位数为28.9 mg/kg;共采集水样150份,水碘中位数为2.76μg/L;学生碘缺乏病知识健康教育问卷及格率为97.11%(874/900),家庭主妇碘缺乏病知识健康教育问卷及格率为98.67%(296/300).结论 三门峡市碘缺乏病防治工作取得了明显的效果,各项监测指标均达到了国家消除碘缺乏病标准.

Abstract：

Objective To investigate the current situation of iodine deficiency disorders and the effect of control measures in Sanmenxia city of Henan province, and to formulate targeted control measures for iodine deficiency disorders. Methods In 2008, five villages(offices) were selected according to the east, west, south,north and center position in each county in 6 counties(cities, districts) of Lingbao, Shan, Hubin, Yima, Mianchi,and Lushi in Sanmenxia city. One primary school was selected in each village(office), fifty students aged 8 - 10 in each primary school were randomly selected to check thyroid and their urine and edible salt were collected to detect iodine. Thirty 5th-grade students in each school were selected to carry out the questionnaire survey of health education about iodine deficiency disorders. According to the east, west, south, north and center position, five potable water samples were selected to detect iodine in the village where the primary school was in. Questionnaire survey was also carried out among ten housewives in the village. Thyroid was examined by palpation;ammonium persulfate digestion-arsenic cerium catalytic spectrophotometry(WS/T 107-2006) was used to detect urinary iodine;direct titration(GB/T 13025-1999 ) was used to detect salt iodine;arsenic cerium catalytic spectrophotometry (GB/T 5750.5-2006) was used to detect water iodine. Results One thousand and five hundreds children aged 8 - 10 were analyzed in 6 counties(cities, districts), the rate of goiter was 3.30%(50/1500), the median of urinary iodine was 273.15 μg/L. One thousand and five hundreds salt samples were detected, the coverage rate of iodized salt was 99.93% (1499/1500), the qualified rate of iodized salt was 98.00% (1469/1499), the edible rate of qualified iodized salt was 97.93% (1469/1500), the coverage rate of non-iodized salt was 0.07% (1/1500), the median of salt iodine was 28.9 mg/kg. One hundred and fifty water samples were collected, the median of water iodine was 2.76 μg/L. The pass rate of the questionnaire survey of health education about iodine deficiency disorders was 97.11% (874/900) in students and 98.67% (296/300) in housewives, respectively. Conclusions The prevention and control of iodine deficiency disorders has achieved significant results and the monitoring indicators have reached the national standard for eliminating iodine deficiency disorders in Sanmenxia city.
