| Objective To understand the based data of KAP situation of iodine and health, nutritional status obtained through diet, iodine content in the diet, intellectual level, so as to provide the basis for guiding children’s behavior of iodine supplementation.Methods Randomly selected650Wa nationality boarding school-age children aged6to14in Shuang jiang lagu nationality,Wa nationality,Bu lang nationality and Dai nationality autonomous county for the survey, With Self-developed questionnaire to investigating the KAP situation of iodine and health,3d24h dietary recall for nutritional status, chemical analysis for iodine content in the whole food of one day, and then to test the intelligence. All survey data were entered to the Epidata3.1database and Excel2003,and then SPSS17.0software was used for the statistical analysis of data.The corrlation between the iodine intake in the mixed diet and the intellectual level was analysed by Spearman rank correlation.Results KAP situation of iodine and health:650questionnaires were distributed,635valid questionnaires, the effective response rate was97.7%. There are308boys (48.5%) and327girls(51.5%) in the635respondents.245people (40.0%) had heard of iodine deficiency disorders, and381(60.0%) had never heard of, The means to access the iodine nutrition knowledge mainly through parents and teachers;There is no statistically significant difference between boys and girls about the awareness of the iodine nutrition knowledge and active behavior of iodine supplementation; The awareness of the iodine nutrition knowledge of higher grades (grades4to6) students is higher than the lower grades (grades1to3) students, differences in the active behavior of iodine supplementation is also true. The students know that iodized salt can effectively prevent iodine deficiency and do not know this knowledge, whose behavior to buy in bulk and bagged salt salt was no statistically significant; There is no statistically significant about the rate of active iodine supplementation between the students who felt themselves lacked iodine and the students did not think so. The energy intake of Wa nationality school-age children in different ages, intake of boys accounted for54%～103%of RNI, girls accounted for RNI58%～110%; protein intake, boys accounted for51%～91%, girls accounted for RNI51%～115%; dietary nutrients of different ages in Wa, vitamin B1, vitamin B2, vitamin A, vitamin E, vitamin C, zinc, calcium, selenium, iodine, etc. do not meet the recommended intake standards. Three dietary nutrients for energy production capacity imbalance, carbohydrates for energy ratio is far higher than the recommended ratio for energy, fat for energy is significantly lower than that recommended for energy. The energy ratios of three meals in a day is within the recommended range, the average dietary iodine intake of each age group was higher than RNI, iodine intake range between RNI-UL. The iodine intake calculated through3d24h dietary recalls method is much lower than the resulting chemical analysis method for the determination. The mental deficiency of Wa boarding school-age students, The intelligence levels of boys and girls were not statistically significant; there is no correlation between the dietary iodine intake levels and the level of intelligence.Conclusion Iodine cotent in the Mixed diet of boarding school-age children has not been reported. This study shows that the way that Wa s boarding chool-age children get iodine nutrition knowledge is relatively limited. The present situation of nutrition KAP among boarding school-age children of the Wa nationality was serious, more ways of health education on iodine nutrition were required for these children. Dietary nutrient intake is generally lower than RNI or AI, three major nutrients for energy production capacity imbalance. Mixed overall dietary iodine intake is appropriate and safe. Intelligence level and dietary iodine intake levels were not correlated. |
