Assessing the dairy consumption and psychological symptoms of Chinese college students as a reference for the mental health of Chinese college students.
A three-stage stratified whole-group sampling method was used to investigate dairy consumption and psychological symptoms among 5904 (2554 male students, accounting for 43.3% of the sample) college students in the Yangtze River Delta region. The mean age of the subjects was 20.13 ± 1.24 years. Psychological symptoms were surveyed using the Brief Questionnaire for the Assessment of Adolescent Mental Health. The detection rates of emotional problems, behavioral symptoms, social adaptation difficulties and psychological symptoms among college students with different dairy consumption habits were analyzed using chi-square tests. The association between dairy consumption and psychological symptoms was assessed using a logistic regression model.
College students from the "Yangtze River Delta" region of China participated in the study, of which 1022 (17.31%) had psychological symptoms. The proportions of participants with dairy consumption of ≤2 times/week, 3-5 times/week, and ≥6 times/week were 25.68%, 42.09%, and 32.23%, respectively. Using dairy consumption ≥6 times/week as a reference, multifactor logistic regression analysis showed that college students with dairy consumption ≤2 times/week (OR = 1.42, 95% CI: 1.18, 1.71) were at higher risk of psychological symptoms ( < 0.001).
During the COVID-19 pandemic, Chinese college students with lower dairy consumption exhibited higher detection rates of psychological symptoms. Dairy consumption was negatively associated with the occurrence of psychological symptoms. Our study provides a basis for mental health education and increasing knowledge about nutrition among Chinese college students.
评估中国大学生的乳制品消费和心理症状，为中国大学生的心理健康提供参考。
采用三阶段分层整群抽样方法，对长三角地区 5904 名（男学生 2554 名，占样本的 43.3%）大学生进行乳制品消费和心理症状调查。调查对象的平均年龄为 20.13±1.24 岁。采用青少年心理健康问卷简表对心理症状进行调查。采用卡方检验分析不同乳制品消费习惯大学生的情绪问题、行为症状、社会适应困难和心理症状检出率。采用 logistic 回归模型评估乳制品消费与心理症状的关系。
来自中国“长三角”地区的大学生参与了研究，其中 1022 名（17.31%）有心理症状。乳制品消费每周≤2 次、3-5 次、≥6 次的比例分别为 25.68%、42.09%和 32.23%。以每周消费≥6 次为参照，多因素 logistic 回归分析显示，每周乳制品消费≤2 次的大学生（OR=1.42，95%CI：1.18，1.71）发生心理症状的风险更高（<0.001）。
在 COVID-19 大流行期间，乳制品摄入量较低的中国大学生表现出更高的心理症状检出率。乳制品消费与心理症状的发生呈负相关。本研究为中国大学生的心理健康教育和营养知识普及提供了依据。
