Investigation of children intelligence endemic iodine

i130 above excellent. Concentration of the test study, unified approach. In strict accordance with the requirements of the two areas tested by the same group of investigators. Results of non-iodine areas of high iodine area and primary intelligence test results (see Table 1). Table 1 area of high iodine area and children's intelligence comparison of non-iodine iodine area of non-iodine areas Gender Male 507 322 999 Total Female 5O7292n37 10073.0710.75 results can be seen from Table 1, iodine district average IQ of children 73.09 non-iodine areas, the average IQ of children in 80.30, both of a significant difference may have an extremely (P ; O.05). Areas of high iodine area and non-IQ distribution of iodine in table 2. From Table 2, the two regions are critical state and the mentally deficient children, but significantly more than non-periodate periodate zone area, the critical state of pure depression and mental mapping the number of mergers, by chi-square test, there was a 167 a ii (((¨ Ming;% 0 Fan mole Museum cheat scorpionfish twist difference (= 14.91, P <0.01). periodate district did not reach the middle and upper case of IQ, rather than one case to the high iodine area fine; middle and lower region, there were more than non-iodine iodine area. the upper, middle, and lower the number of cases ancient, the chi-square test, two significant differences between regions (a 14.91. P <O.O1). Table 2 with non-iodine areas of high iodine area to discuss the findings show that the IQ distribution, the intellectual level of students of high iodine area of high iodine area has pull with non-significant difference (P <0.01), shows high Like iodine, as iodine deficiency, affecting children's intellectual development. Our results with the views of some scholars is the same 0], and another point of view of some scholars is different]. 6-year-old former children's intellectual development of a critical period to 7 Children over the age as the test object is meaningful. Although intelligence by many factors, but our children in the two regions surveyed have a good comparability of years of education of students, school size, teacher standards, economic status, living standards are similar. There were significant differences in intelligence. iodine is mainly due to the water. from the general intellectual level, the agricultural btl '~ dry city. If you follow the conventional classification criteria to measure intelligence in rural areas, the level l is not appropriate, it is necessary develop appropriate classification standard IQ.
