Purpose: study during the school year at the autonomic nervous system functional state primary school children from iodine deficiency.
Materials and methods. The study involved 239 children aged 6–10 years. We determined the iodine in urine and heart rate variability.
Results. At the end of the school year, compared to the beginning, children of class 1 secured iodine index decreased adequacy regulation processes by 11% (p<0,05), relationship stress index in the sample to the index in the background stress test at 38% (p<0,05). Children in class 2 with iodine deficiency observed increase amplitude of fashion for 21% (p<0,05), an indicator of the adequacy of regulation processes by 26% (p<0,05), stress index by 56% (p<0,05). In fourth-observed performance index increase tension by 28% (p<0,05) and reduction of the standard deviation of 37% (p<0,05).
Conclusions. Found that in children with iodine deficiency prevails sympatyc effect autonomic nervous system.
