A survey conducted in 1964 reported a goitre prevalence of 40.3% in East and West Champaran districts of Bihar. No recent survey has been documented on the prevalence of iodine deficiency in these districts. The present study was therefore undertaken (i) to assess the prevalence of IDD in these districts, and (ii) to estimate the iodine content of salt consumed by population.
In each district, one block was selected. In each block more than 630 children in the age group of 6-12 years were included in the study and were clinically examined. Urine samples were collected from 261 children and were analyzed using standard laboratory procedures. A total of 456 salt samples were collected from children and 35 from traders from the two districts and analyzed using the standard iodometric titration method.
The total goiter prevalence was 11.6%. The percentage of children with < 2, 2.0-4.9, 5.0-9.9 and > or = 10 mcg/dl of urinary iodine excretion level were 12.3, 13.4, 23.4 and 51.0, respectively. The median urinary iodine excretion of the children was 10.0 mcg/dl. None of the families were consuming salt with a nil iodine content and about 29.3%, were consuming salt with less than 15 ppm of iodine. Of the 35 salt samples collected from traders, all had iodine and about 17% had less than 15 ppm of iodine.
The study stresses the need for strengthening the existing system of monitoring of quality of salt being provided in the East and West Champaran districts by Government of Bihar.
1964年进行的一项调查显示，比哈尔邦东、西昌帕兰县的甲状腺肿患病率为40.3%。目前尚无关于这些地区碘缺乏症患病率的近期调查记录。因此开展了本研究，（i）评估这些地区碘缺乏病的患病率，（ii）估算人群食用盐的碘含量。
在每个县选择一个街区。在每个街区，630多名6至12岁的儿童被纳入研究并接受临床检查。从261名儿童中收集尿液样本，并使用标准实验室程序进行分析。从两个县的儿童和商人那里共收集了456份盐样本和35份盐样本，并使用标准碘量滴定法进行分析。
甲状腺肿总患病率为11.6%。尿碘排泄水平<2、2.0 - 4.9、5.0 - 9.9和≥10 mcg/dl的儿童百分比分别为12.3%、13.4%、23.4%和51.0%。儿童尿碘排泄中位数为10.0 mcg/dl。没有家庭食用碘含量为零的盐，约29.3%的家庭食用碘含量低于15 ppm的盐。从商人那里收集的35份盐样本中，所有样本都含碘，约17%的样本碘含量低于15 ppm。
该研究强调比哈尔邦政府需要加强对东、西昌帕兰县所供应盐质量的现有监测系统。
