某高校护理和预防两个专业大学生核黄素营养状况分析

目的了解大学生核黄素营养状况，并探讨其影响因素。方法对护理、预防专业的学生进行核黄素4h负荷尿试验，用荧光光度法测定核黄素含量。结果护理学专业的学生核黄素不足的占78．79％，正常占10．10％，充裕的占11.31％。预防医学专业的学生核黄素不足的占74．42％，正常的占16．28％，充裕的占9．3％。专业之间差异无显著性意义（P〉0．05）。结论大学生的核黄素营养水平普遍较低，其中动物性食品摄人较少、学生对合理膳食的营养知识缺乏是核黄素摄人不足的主要原因。

Evaluation Study on Nursing and Preventive Medical Professional University Student Riboflavin Nutritional Status

Objective To understand the riboflavin nutritional status and the influencing factors. Methods The nursing and preventive medicine university students were carried out a 4-h riboflavin burden urine experiment, and the fluorescence spectrophotometry was used to monitor the urinary riboflavin content. Result The proportion of students with shortage, adequate, or rich were 78.79%,10.10%,and 11.31% among the nursing school students and 74.42%,16.28%,and 9.3% among the preventive medicine school students respectively, which showed insignificant difference between the 2 schools (P>0.05). Conclusion Deficiency of riboflavin among university students is widespread; it is due to insufficient animal foods and inappropriate nutritional knowledge of the students.
