山西内陆水源性高碘流行病学调查

Epidemiological survey of inland water-borne high iodine in drinking water in Shanxi Province.

目的调查山西省高碘水源的分布,掌握高碘甲状腺肿病情和人群碘营养状况,为制定和落实防治措施提供科学依据。方法采用流行病学横断面调查方法,进行水碘抽样调查,在水碘>150μg/L的乡开展儿童甲肿率和尿碘抽样调查。结果10个县29个乡镇水碘中位数>150μg/L,11个乡>300μg/L;26个乡镇8～10岁儿童甲肿率>5%;27个乡儿童尿碘中位数>400μg/L,9个乡>800μg/L。结论3个乡可判定为高碘地区,26个乡镇为高碘病区。应采取有效的防治措施。

Objective To investigate the distribution of high iodine in drinking- water in Shanxi province, and understand the goiter prevalence and the iodine- nutrition status in the areas of high water iodine, which will provide the scientific evidence for the establishment and implementation of preventive countermeasure. Methods By adopting cross - sectional study, water samples were collected, and goiter rate and urinary iodine in 8 to 10 years old children were investigated. Results The medians of water iodine were higher than 150μg/L in 29 towns; were higher than 300μg/L in 11 towns. The average goiter rates were higher than 5% in 8 to 10 years old children in 26 towns. Medians urinary were higher than 400μg/L in 8 to 10 years old children in 27 towns; were higher than 800μg/L in 9 towns. Conclusion 3 towns were confirmed as the areas of high water iodine. 26 towns were confirmed as the endemic areas of iodine excess goiter. Effective countermeasure should be adopted immediately.
