医学生营养状况及知识态度行为调查

目的 探讨不同地区生源医学生营养状况及影响因素,并调查其营养知识、态度及行为,为相关干预研究提供参考依据。方法 采用体质指数评价学生现时营养状况,对1 096名医学生进行营养知识-态度-行为及营养状况问卷调查。采用χ²检验和Logistic回归进行影响因素分析。结果 医学生营养不良率为15.3%;超重和肥胖率为3.5%。32.2%的城市学生、16.9%的农村学生营养态度及饮食行为较好。城市学生的营养态度普遍比农村学生积极,且饮食行为也比农村学生健康。城市和农村学生的营养知识知晓率差异无统计学意义。性别、母亲文化程度、每天吃早餐、晚上加餐以及偏食是营养状况的影响因素,其中性别、母亲文化程度、每天吃早餐为保护因素,晚上加餐、偏食为危险因素。结论 应加强农村学生饮食行为的正确引导,并帮助其端正营养态度。
