我们打算使用来自“智能订购系统”(IOS)的食堂数据来精确评估男女医学院学生的饮食质量,结合补充食物频率问卷(SFFQ)和中国健康饮食指数(CHEI),中国,探讨影响膳食质量的潜在因素。本研究共招收283名在校大学生,平均年龄为24.67±3.21岁,体质指数为21.46±3.49kg/m2,并进行了在线问卷调查以收集一般信息,生活方式行为,SFFQ来自学校食堂的研究参与者的饮食数据从复旦大学信息办公室的IOS导出。CHEI由17个成分组成,总分为100,每个成分的最高得分为5或10。我们计算了CHEI的每个组成部分得分,并汇总了男性和女性研究参与者的总分。采用卡方检验和Wilcoxon秩和检验比较了男性和女性的人口统计学特征和CHEI成分得分之间的差异。采用单因素和多元线性回归模型分析CHEI总分的潜在影响因素。CHEI中位数评分为66.65,总谷物的成分评分相对较低。添加的糖是最过度消耗的CHEI组分。存在比较严重的缺陷,基于CHEI分量分数,在水果中,大豆,鱼和海鲜,以及两性的种子和坚果。女性的CHEI得分明显高于男性(68.38对64.31)。块茎的分数,总蔬菜,深色蔬菜,水果,鱼和海鲜,乳制品,女性的红肉含量明显高于男性。影响因素包括性别,教育,饮食健康素养,和长期花费的时间与CHEI评分显著相关。我们的研究表明,上海医学院大学生的整体饮食质量需要进一步提高,中国,总谷物摄入量低,水果,大豆,鱼和海鲜,种子和坚果,和高摄入量的添加糖。与男性相比,女性表现出更高的饮食质量,并且更强烈地符合推荐的中国饮食指南。教育,饮食健康素养,要提高大学生的饮食质量,应注意花费大量的时间。
We intended to precisely evaluate the dietary quality of male and female medical college students using canteen data from the \"Intelligent Ordering System\" (IOS), combined with the supplemental food frequency questionnaire (SFFQ) and the Chinese Healthy Eating Index (CHEI) in Shanghai, China, to explore the potential factors influencing dietary quality. A total of 283 college students with the average age of 24.67 ± 3.21 years and Body Mass Index of 21.46 ± 3.49 kg/m2 in the medical school were enrolled in this study, and an online questionnaire investigation was conducted to collect the general information, lifestyle behavior, and SFFQ. The dietary data of the study participants from the school canteen were exported from the IOS of the Information Office of Fudan University. The CHEI consists of 17 components and the total score is 100, with a maximum score of each component of 5 or 10. We calculated each component score of the CHEI and aggregated the total score for male and female study participants. The Chi-square test and Wilcoxon rank sum test were employed in comparing the differences between the demographic characteristics and CHEI component scores of males and females. Univariate and multiple linear regression models were employed to examine the potential influencing factors of the total CHEI score. The CHEI median score was 66.65, and the component score for total grains was relatively low. Added sugars was the most overconsumed CHEI component. There were relatively serious deficiencies, based on the CHEI component scores, in fruits, soybeans, fish and seafood, and seeds and nuts in both sexes. Females had significantly higher CHEI scores than males (68.38 versus 64.31). The scores for tubers, total vegetables, dark vegetables, fruits, fish and seafood, dairy, and red meats were significantly higher in females than in males. Influencing factors including sex, education, dietary health literacy, and amount of time spent sedentarily were significantly associated with CHEI score. Our research revealed that the overall dietary quality needs to be further improved for college students at the medical school in Shanghai, China, with low intakes of total grains, fruits, soybeans, fish and seafood, and seeds and nuts, and high intakes of added sugars. Compared with males, females showed higher diet quality and conformed more strongly with the recommended Dietary Guideline for Chinese. Education, dietary health literacy, and amount of time spent sedentarily should be noted for improving the dietary quality of college students.
