Universal salt iodization (USI) is long term strategy for the control of iodine deficiency disorder (IDD) in Nepal. Standardized periodic testing of the iodine content in salt is a critical part of a salt iodisation programme. To achieve programmatic objective, this study was carried out to estimate the iodine content of household salt in Kavre, Lalitpur and Parsa districts of Nepal. Iodometric titration of 1803 salt samples collected from the households through the students of different schools revealed that 289 (16.0%) had less than 15 ppm iodine. Two hundred forty-one powder salt samples without two children logo (14.3% among total powder salt samples) had iodine below 15 ppm. It includes 25.8% of total salt samples from Parsa district of Terai ecological region. Among total, the largest proportion of the population accounting for almost 93.0% used powder salt. In total 1803 salt samples, mean and median iodine concentration were 31.8 ppm (95.0% CI=31.0-32.6) and 29.5 ppm respectively. The mean and median iodine concentration of phoda (dhike) salt were 22.1 ppm (95.0% CI= 19.2-25.1) and 18.9 ppm; powder salt were 32.6 ppm (95.0% CI= 31.7- 33.4) and 30.6 ppm respectively. In the community level, people are still using the non-iodized salt. To eliminate the IDD more efforts are required at program implementation and monitoring level.
全民食盐加碘（USI）是尼泊尔控制碘缺乏病（IDD）的长期战略。对食盐碘含量进行标准化定期检测是食盐加碘计划的关键部分。为实现该计划目标，开展了本研究以估算尼泊尔卡夫雷、拉利特布尔和帕尔萨地区家庭食盐的碘含量。通过不同学校的学生从家庭收集的1803份食盐样本的碘量滴定显示，289份（16.0%）碘含量低于15 ppm。241份没有双童标志的粉状食盐样本（占粉状食盐样本总数的14.3%）碘含量低于15 ppm。这包括来自特莱生态区帕尔萨地区的食盐样本总数的25.8%。总体而言，使用粉状食盐的人口比例最大，几乎占93.0%。在总共1803份食盐样本中，碘浓度的均值和中位数分别为31.8 ppm（95.0% CI = 31.0 - 32.6）和29.5 ppm。粗盐（dhike）的碘浓度均值和中位数分别为22.1 ppm（95.0% CI = 19.2 - 25.1）和18.9 ppm；粉状食盐分别为32.6 ppm（95.0% CI = 31.7 - 33.4）和30.6 ppm。在社区层面，人们仍在使用未加碘食盐。为消除碘缺乏病，在计划实施和监测层面需要做出更多努力。
