This study aims to determine the quantitative relationships between urinary iodine concentration (UIC), the prevalence of goiter, and behavioral disorders as a consequence of height, weight, and salt iodine concentration. </span></span></span><b><span style="font-size:10.0pt"><span style="line-height:107%"><span new="" roman="" style="font-family:" times="">Methods:</span></span></span></b><span style="font-size:10.0pt"><span style="line-height:107%"><span new="" roman="" style="font-family:" times=""> The urinary and salt iodine concentrations were measured using the </span></span></span><span style="font-size:10.0pt"><span style="line-height:107%"><span new="" roman="" style="font-family:" times="">Chlorometric method and iodine detector kit, respectively. The differences between the two groups and the relationship between these variables and endpoints were determined using t-test and Pearson correlation with a significance level of 0.05, respectively. Quantitative relationships between them were also modeled using linear and nonlinear models&rsquo; artificial neural network (ANN) in MATLAB2020. <b>Results:</b> According to the results and linear modeling, iodine concentration and behavioral disorders based on variables of height, weight, and iodine salt concentration were randomly distributed. Also, limited nonlinear relationships between UIC and variables of height, weight, salt iodine concentration and behavioral disorders were obtained as a consequence of variables of height, weight, salt iodine concentration, and urinary output in ANN (R<0.7). <b>Conclusion:</b> </span></span></span><span style="font-size:10.0pt"><span style="line-height:107%"><span new="" roman="" style="font-family:" times="">Modeling the relationship between these variables using ANN showed there were limited nonlinear relationships between urinary iodine and variables of height, weight, and iodine salt concentration. </span></span></span><span style="font-size:10.0pt"><span style="line-height:107%"><span new="" roman="" style="font-family:" times="">Thus, to determine the effective factors and the quantitative relationship between them, it is suggested to study other variables in future studies</span></span></span></div> Iodine, Iodized salt, Goiter, IDD, Socioeconomic factors,Demographic factors. 120 132 http://jnfs.ssu.ac.ir/browse.php?a_code=A-10-1475-1&slc_lang=en&sid=1 Mahrokh Jalili 0000-0002-8397-4112 No Genetic and Environmental Hazard Research Center, Abarkouh School of Medical Sciences, Shahid Sadoughi University of Medical Sciences, Yazd, Iran Mohammad Hassan Ehrampoush No Environmental Science and Technology Research Center, Shahid Sadoughi University of Medical Sciences, Yazd, Iran , Maryam Azizi No Abarkouh School of Medical Sciences, Shahid Sadoughi University of Medical Sciences, Yazd, Iran Fariba Abbasi Faribaabbasi10@gmail.com Yes Systems Environmental Health and Energy Research Center, The Persian Gulf Biomedical Sciences Research Institute, Bushehr University of Medical Sciences, Bushehr, Iran.
