Abstract:
Objective To find out the status of prevention and control of iodine deficiency disorders and evaluate the iodine nutritional status of Jinan residents,to explore appropriate iodine level in drinking water,and to provide a scientific basis for adjustment of intervention strategies.MethodsAccording to the Monitoring Program of the National Iodine Deficiency Disorders (Trial),qualified iodized salt consumption rate,drinking water iodine content and urinary iodine levels of women of childbearing age were determined in iodine deficiency areas from 2003 to 2010.Salt iodine was detected by direct titrimetry,urinary iodine by As-Ce catalytic spectrophotometric assay and iodine in drinking water by cerous sulfate catalytic spectrophotometric method.Results Intake rate of qualified iodized salt was up to 90％ and above from 2003 to 2010,median water iodine was 13.65 μg/L in the 10 counties(cities,districts),of which less than 100 μg/L accounted for 79.82％(4560/5713 ) and ＞ 150 μg/L accounted for 12.73％(727/5713).With the increase of water iodine(0 ～ ＜ 10,10 ～ ＜ 50,50 ～ ＜ 100,100 ～ ＜ 150,150 ～ ＜ 300 and ≥300 μg/L),urinary iodine levels of women of childbearing age increased successively(median 156.56,175.81,267.04,349.00,524.22,583.20 μg/L,respectively,x2 =121.20,P ＜ 0.05),while the ratio of urinary iodine ＜ 100 μg/L was significantly lower.The ratio of urinary iodine between 100 and 300 μg/L was decreased gradually,but the ratio of great than 300 μg/L was gradually increased.ConclusionsIodine deficiency areas in Jinan have reached the standard of elimination of iodine deficiency disorders.We should insist to carry out our measures to suit local conditions,classified guidances and scientific principals of iodine supplementation.
