摘要
目的了解大学生营养状况、营养知识的知晓情况,以便为提高大学生的营养健康水平提供依据。方法采用分层整群抽样的方法抽取某医学院校3~4年级本科学生205人,对其进行问卷调查、体格检测和实验室检查。结果医学生对营养相关知识平均得分为（80.53±11.99）分,女生高于男生（t=5.61,P〈0.01）;护理学专业（86.60±10.27）高于预防医学专业（79.41±11.87）,高于临床医学专业（75.91±11.28）,专业间差异具有统计学意义（F=18.39,P〈0.01）;医学生获取营养知识的途径主要来源于课堂教学（64.5%）、书刊报纸（46.0%）和电视广播（15.5%）;BMI指数女生倾向于营养不良,消瘦发生率为27.2%,男生倾向于营养过剩,超重发生率为14.3%;男生锌、铁缺乏率分别为73.5%和8.2%,女生分别为80.8%和32.5%,铁缺乏率在性别之间差异具有统计学意义（χ2=11.20,P〈0.05）结论医学生对营养相关知识掌握情况总体较好,但营养不良发生率较高,女性血清铁和总体血清锌含量偏低。
Objective To understand the nutritional status and the awareness of nutritional knowledge among college students,and provide scientific basis for improvement of nutritional status among college students.Methods Stratified cluster sampling was used and 205college students of 3-4grade were surveyed with a questionnaire,physical and experimental examination.Results Medical students scored 80.53±11.99on nutritional knowledge,which was higher in female than in male students（t=5.61,P〈0.01）and highest in students of Nursing Specialty（86.60±10.27）than students of Preventive medicine specialty（79.41±11.87）and clinical medicine specialty（75.91±11.28）with significant statistical difference.The nutritional knowledge of medical students came from classroom teaching（64.5%）,books and newspapers（46.0%）,and TV and radios（15.5%）. Female students tended to be malnourished with prevalence rate of underweight 27.2%,while male students tended to overnutrition with prevalence rate of overweight 14.3%.The zinc and iron dificiency rate was 73.5% and 8.2%among male students and was 80.8% and 32.5% among female students,with statistical difference between two sexes on dificiency rate of zinc（χ2=11.20,P〈0.05）.Conclusion The overall status of acquisition of nutritional knowledge is good.The prevelence rate of malnutrition is high,and the concentration of serum iron,zinc, is low in female students.
