Abstract

Aim: To evaluate the household iodine content and knowledge, attitude, and behavior regarding salt iodization among the residents of Cumilla, Bangladesh. Subjects and Methods: We conducted a cross-sectional survey of 700 inhabitants in Cumilla's urban and rural areas to determine the iodine concentration of salt they consume. The participants were asked about what they know about iodine deficiency and salt iodization as well as how their salt was packaged and stored. Among them, 338 people provided a sample of salt to be tested of its iodine content by the titrimetric method. Results: 46.57% of people knew that iodization was the best way to prevent iodine deficiency while 35.14% considered salt iodization during purchasing. Most people stored salt in plastic boxes (89.7%) and closed containers (84.14%).Among all participants, only 37.14% of people were aware of the iodine requirement during pregnancy. In urban regions, the median iodine content was 36.76 ppm (OR=0.658, 95% CI, 0.469-0.925), while in rural areas, the median iodine content was 40.92 ppm (OR=1.188, 95% CI, 1.022-1.380). Iodine levels were less than 15 ppm (minimum limit) in 6.8% of samples and greater than 40 ppm (maximum limit) in 56.5%. Only 36.7% of the salt samples contained adequate iodine. Conclusion: An effective and consistent approach for controlling iodine concentration in distributed salt is required at Cumilla, Bangladesh.
