目的了解大庆市大学生碘营养现状及对碘缺乏病(IDD)知识的掌握情况,为消除碘缺乏病提供依据。方法对大庆市6所高校在校大学生按容量比例(PPS)法抽样,进行甲状腺肿大情况、尿碘、血清甲状腺素(T4)及盐碘的检测,并调查碘营养知识的掌握情况。结果大学生甲状腺肿大率为4.30%,尿碘中位数为314.35μg/L,不同专业及不同性别大学生之间差别均无统计学意义(P值均>0.05);甲状腺素(T4)平均浓度为(105.68±49.21)nmol/L;学校食堂盐碘合格率为95.00%;85.67%大学生知道缺碘导致甲状腺肿大,而知道缺碘导致智力低下的只有29.49%;90.45%知道食用碘盐是预防碘缺乏病(IDD)的最佳方式;18.82%通过媒体获得IDD防治知识;15.73%能向他人宣传IDD知识。结论大庆市大学生碘营养状况较好。现阶段采取食盐加碘为主的干预措施是改善碘营养行之有效的途径,但还有必要在大学生中进一步开展IDD知识的相关教育。
Objective To understand the current status of iodine nutrition and knowledge of iodine deficiency disorders (IDD) among college students in Daqing, and to provide a basis for eliminating iodine deficiency disorders. Methods Six students from 6 universities in Daqing City were enrolled in this study according to the volume proportion (PPS) method. Thyroid enlargement, urinary iodine, serum thyroxine (T4) and salt iodide were measured. The mastery of iodine nutrition knowledge was investigated. Results The prevalence of goitre was 4.30%, and the median urinary iodine was 314.35μg / L. There was no significant difference between different majors and undergraduates (P> 0.05). The average thyroxine (105.68 ± 49.21) nmol / L; the passing rate of salt and iodine in school canteens was 95.00%; 85.67% of college students knew that iodine deficiency caused goiter; only 29.49% knew that iodine deficiency caused mental retardation; 90.45% The best way to prevent iodine deficiency disease (IDD); 18.82% get IDD prevention and control information through the media; 15.73% can promote IDD knowledge to others. Conclusion Daqing students iodine nutrition is better. At this stage, taking salt and iodine-based interventions is an effective way to improve iodine nutrition, but there is still a need to further develop IDD-related education among college students.
