【摘要】：目的了解合肥市大学生和8~10岁小学生的碘营养状况以及大学生对碘相关疾病防治知识的认知水平,为科学制定相关人群碘营养补充政策提供参考。方法在合肥市某高校随机选取6个班共326名大学生进行尿碘的检测,同时进行问卷调查;以随机抽样的方法在合肥市9个区/县选取900位8~10岁小学生作为调查对象进行尿碘检测。结果大学生和小学生的尿碘中位数分别为380.0μg/L和225.2μg/L,其中68.4%的大学生处于碘过量状态(300μg/L),59.7%的小学生尿碘处于超适宜以上水平(200μg/L)。大学生和小学生之间的尿碘水平差异有统计学意义(Z=-13.74,P=0.00)。问卷调查显示,不同性别大学生尿碘值差异无统计学意义(P0.05),常食用含碘量丰富食物(如海带、紫菜、虾、海鱼)的大学生尿碘值明显偏高(P值均0.05),但吸烟、饮酒、锻炼、睡眠等生活习惯对尿碘值的影响均无统计学意义(P值均0.05)。大学生碘相关知识问答的平均得分为49.5分,60分以上的仅占总人数的18.9%。结论合肥市大部分小学生处于碘营养超适宜水平,大学生则存在明显的碘过量现象。应根据不同的人群特点合理地进行补碘。
[Abstract]:Objective to investigate the iodine nutrition status of college students and primary school students aged 8 ~ 10 years in Hefei and their knowledge of iodine related diseases, so as to provide a reference for the scientific formulation of iodine nutrition supplement policy for the relevant population. Methods A total of 326 college students from 6 classes in Hefei were randomly selected for urinary iodine detection, and questionnaire survey was conducted at the same time. Nine districts / counties of Hefei were randomly sampled to detect urine iodine of 900 8- and 10-year-old pupils. Results the median urinary iodine levels of college students and pupils were 380.0 渭 g / L and 225.2 渭 g / L, respectively. 68.4% of the students were in iodine excess (300 渭 g / L), and 59.7% of the pupils were above the appropriate level (200 渭 g / L). There was significant difference in urinary iodine level between college students and primary school students (ZT- 13.74 P0. 00). The questionnaire survey showed that there was no significant difference in urinary iodine values among different genders (P0.05). The urinary iodine values of college students who often ate iodine rich foods (such as kelp, porphyra, shrimp, sea fish) were significantly higher (P < 0.05), but smoking, drinking, exercising, and so on. There was no significant difference in the effect of sleep and other living habits on urinary iodine value (P < 0.05). The average score of iodide related knowledge of college students was 49.5 points, and those above 60 points accounted for only 18.9% of the total. Conclusion most primary school students in Hefei are in the excess of iodine nutrition level, but there is obvious iodine excess in college students. Iodine supplementation should be carried out reasonably according to the characteristics of different population groups.
