摘要:目的：通过调查杭州师范大学在校学生的膳食摄入情况，了解其钙摄入情况以及对钙相关知识的认知现状，探究影响大学生摄入钙的影响因素，为大学生的营养干预提供基础信息。方法：本研究采用方便抽样的方法从杭州师范大学仓前校区和下沙校区抽取390位学生进行问卷调查，调查内容分为一般情况和钙消费情况调查两部分。钙消费情况调查内容包括钙相关营养知识、钙相关消费习惯、个人饮食习惯和食物频率调查四部分。食物频率调查的问题设置是根据半定量食物频率问卷制定，调查结果利用营养计算软件计算钙摄入量。此外，还对学生的钙消费情况进行分析。结果：女生钙膳食摄入量均值为975.30mg，标准差为367.66，达到钙推荐摄入量的比例为66.9%；男生钙膳食摄入量均值为869.83mg，标准差为469.63，达到钙推荐摄入量的比例为51.9%。性别（P<0.05）,喜好饮料（p<0.05）,服用钙补充剂（p<0.05）为钙膳食摄入量的影响因素。建议大学生平时多食用乳制品，保证正常合理的饮食习惯，尽量规律的食用三餐，如有必要可适当补充钙制剂。

Abstract:Objective: get a picture of  calcium intake and awareness of calcium related knowledge in Hangzhou Normal University through the investigation of  students' dietary intake.
