目的调查天津市高校大学生尿碘水平,评估该人群碘营养状况并分析其影响因素.方法 2011年选取天津市高校(天津医科大学、南开大学、天津财经大学、天津中医药大学)在校学生作为调查对象,分别抽取50～ 100名学生,采集晨起尿样,硫酸铵消化-砷铈催化分光光度法测定尿碘,同时进行碘营养状况问卷调查,内容涉及一般家庭情况、年龄、性别、所学专业、碘营养知识、饮用水源、吸烟状况、肉蛋食用情况等.结果共采集尿样269份,尿碘中位数为213.68 μg/L;医学专业学生尿碘水平(263.86 μg/L)明显高于非医学专业学生(168.01 μg/L,x2=12.144,P＜0.01)；碘营养知识分数＞5分者尿碘水平(223.70 μg/L)与≤5分者(185.56μg/L)比较,有升高趋势,但差异无统计学意义(x2=2.297,P＞0.05)；不同性别和饮水来源对学生尿碘水平未见明显影响(x2值分别为0.002、0.687,P均＞0.05)；吸烟者尿碘水平(154.55 μg/L)与非吸烟者(215.38μ g/L)比较,有降低趋势,但差异无统计学意义(x2=0.515,P＞0.05)；素食者尿碘水平有低于非素食者的趋势,但差异无统计学意义(x2=0.594,P＞ 0.05).结论天津市高校大学生碘营养状况基本处于适宜水平,但是专业知识、生活习惯等因素可能会对碘的摄入量造成影响,因此大学生应养成良好的饮食生活习惯,以保证正常碘营养状况.

Objective To evaluate the iodine nutritional status of university students in Tianjin and analyze influencing factors affecting urinary iodine levels.Methods Students of Tianjin Medical University,Tianjin Nankai University,Tianjin University of Finance and Economics and Tianjin University of Traditional Chinese Medicine were selected as survey subjects,and 50 - 100 morning urinary samples were collected from each university,respectively.Urinary iodine was measured by arsenic-cerium catalytic spectrophotometry.The students were surveyed with questionnaires,which included family information,age, sex, specialty, iodine nutrition knowledge,source of drinking water,smoking or not and dietary habits.Results A total of 269 urine samples were collected,and the median urinary iodine was 213.68 μg/L.Urinary iodine levels(263.86 μg/L) of medical students was significantly higher than that( 168.01 μg/L,x2 =12.144,P ＜ 0.01 ) of non-medical students.There was an increasing trend of the level of urinary iodine of students with iodine nutrition knowledge scores ＞ 5 points (223.70 μg/L) over that of ≤5 points( 185.56 μg/L),but the difference was not significantly different statistically (x2 =2.297,P ＞ 0.05).Different gender and water sources had no significant effect on urinary iodine level(x2 =0.002,0.687,respectively,all P ＞ 0.05).Smokers urinary iodine levels( 154.55 μg/L) decreased compared with non-smokers(215.38 μg/L),but the difference was not statistically significant (x2 =0.515,P＞ 0.05).Vegetarian urinary iodine levels were lower than that of non-vegetarians,but the difference was not statistically significant(x2 =0.594,P ＞ 0.05).Conclusions Iodine nutritional status of students in university of Tianjin are generally at an appropriate level,but professional knowledge,habits and other factors may affect the intake of iodine,so students should develop good dietary habits to ensure a normal iodine nutrition status.
