目的比较不同干预方式提高某校高职医学生营养知识的效果,为制定有效的营养干预措施提供科学依据。方法采用整群随机抽样方法,抽取某校高职医学生319名,用自行设计问卷进行调查。结果干预前后学生营养知识知晓率总体上有显著提高(P<0.05),知晓率等级差异有统计学意义(P<0.001);通过宣传海报、校园广播和黑板报宣传方式进行干预的学生干预前后营养知识知晓率等级差异无统计学意义(P=0.179);通过宣传海报、校园广播、黑板报宣传和接受营养相关课程方式进行干预的学生干预前后营养知识知晓率等级有显著提高(P<0.001)。结论该校高职医学生的营养知识知晓率较低,宣传海报、校园广播和黑板报宣传的传统营养干预方式效果不明显。营养相关课程是最为有效的干预方式,建议各医学院校开设营养相关课程以增强学生营养知识。
Objective To compare the effects of different interventions on improving nutritional knowledge of medical students in a higher vocational school and to provide a scientific basis for making effective nutritional interventions. Methods A cluster random sampling method was used to extract 319 medical students from a certain university and to conduct self-designed questionnaires. Results Before and after the intervention, the students ’awareness of nutritional knowledge was significantly improved (P <0.05), and there was significant difference in the level of awareness (P <0.001). Before and after the students’ intervention through posters, campus radio and blackboard newspaper There was no significant difference in the level of awareness of nutritional knowledge (P = 0.179). There was a significant increase in the level of awareness of nutritional knowledge before and after intervention by propaganda posters, campus radio, blackboard publicity and nutrition-related curriculum (P <0.001 ). Conclusion The nutrition awareness of medical students in higher vocational schools is low, and the effect of traditional nutrition interventions propaganda posters, campus radio and blackboard newspapers is not obvious. Nutrition-related courses are the most effective interventions and we recommend that medical schools offer nutrition-related courses to enhance students’ nutritional knowledge.
