部分在校大学生碘营养状况调查

目的：对部分在校大学生的膳食碘摄人及尿碘水平进行调查，综合评价其碘营养现况，为科学、合理的食盐补碘提供参考。方法：以天津医科大学部分在校生为调查对象，共选取95人，其中男生55人，女生40人，进行7日膳食调查，计算其膳食碘摄人量；从学校各个水房及食堂采集饮水及食盐，测定其水碘及盐碘含量；采集调查对象空腹晨尿．用砷铈催化分光光度法测定尿碘水平。结栗：95名调查对象平均碘摄人量为（104．56±24-48）vega，通过食盐加碘后，每人每13的总碘摄入量为（368．07±25．32）μg，d；调查对象尿碘中位数为347．40pg/L，尿碘范围在46．60～1487．00μgm．其中3例尿碘水平〈100μg/L者占总调查人数的3．16％，而〉300μg/L者有52例，占54．74％。结论：这部分学生通过膳食摄人的碘量低于碘的推荐摄人量（RNI）．有必要通过食盐加碘来补充碘摄入量。但经食盐加碘补碘后，尿碘水平显示其存在碘摄入过量，提示适当减少碘盐的摄入量，避免碘摄入过量引起的甲状腺疾病。

Investigation on iodine nutritional status of undergraduate students

Objective:To evaluate the current iodine nutritional status of students from the dietary iodine intake and the level of urine iodine,provide data support to salt iodization.Methods:95 students were selected,of whom 55 boys,40 girls,7th dietary survey was carried out to calculate the dietary intake of iodine;collected water and salt from every canteen in school,then measured the iodine levels;their morning urine were collected and urine iodine was determined by arsenic-cerium catalytic spectrophotometry.Resu...
