The purpose of this study was to determine the behavior of housewives, the level of availability, and the level of consumption of iodized salt with the incidence of IDD. This type of research is observational with a cross-sectional design. The sample is all mothers who have children in grades 3, 4, and 5 in the Buana Giri 7 public elementary school, totaling 80 people. Data were collected by interview, observation, and weighing methods. The quality of iodized salt was tested using the iodine test. Goiter grade was obtained by the palpation method. The data that has been collected were analyzed with Pearson correlation. The level of knowledge, attitude, and practice of iodized salt are still low so it needs to be improved. The level of availability of iodized salt on average still low (3.8 g/person/day) and the level of consumption of iodized salt (2.1 g/person/day). Goiter grade entire sample was normal. Behavior-related knowledge (r = 0.8) and practice (r = 0.8) of iodized salt, but the behavior is not related to the availability (r = 0.024) and iodized salt consumption (r = -0.09). Contributions behavior is very weak against the availability and consumption of iodized salt.
