BACKGROUND
The frequency of take-out food consumption has increased rapidly among Chinese college students, which has contributed to high obesity prevalence. However, the relationships between take-out food consumption, body mass index (BMI), and other individual factors influencing eating behavior among college students are still unclear. This study explored the association of take-out food consumption with gender, BMI, physical activity, preference for high-fat and high-sugar (HFHS) food, major category, and degree level among Chinese college students.
METHODS
Cross-sectional data were collected from 1220 college students in Beijing, China, regarding information about take-out food consumption, physical activity, and preference for HFHS food using a self-reported questionnaire. The logistic linear regression model was used to analyze the association between take-out food consumption and personal and lifestyle characteristics.
RESULTS
Out of 1220 college students, 11.6% of college students were overweight or obese. Among the personal and lifestyle characteristics, high frequency of take-out food consumption was significantly associated with a non-medical major, high preference for HFHS food, degree level, and higher BMI, but not physical activity.
CONCLUSION
Among Chinese college students, consumption of take-out food may be affected by major category, preference for HFHS food, degree level, and BMI. This could provide guidance on restrictions of high take-out food consumption, which contributes to high obesity prevalence and high risk for metabolic diseases.
背景
中国大学生的外卖食品消费频率迅速增加，导致肥胖率居高不下。然而，外卖食品消费与大学生饮食行为的个体因素（如体重指数（BMI）、体力活动、对高脂肪高糖（HFHS）食物的偏好）之间的关系仍不清楚。本研究探讨了外卖食品消费与性别、BMI、体力活动、对 HFHS 食物的偏好、专业类别和学历水平在大学生中的关系。
方法
本研究采用横断面研究方法，从中国北京的 1220 名大学生中收集有关外卖食品消费、体力活动和对 HFHS 食物偏好的信息，使用自我报告问卷。采用逻辑线性回归模型分析外卖食品消费与个人和生活方式特征之间的关联。
结果
在 1220 名大学生中，有 11.6%的大学生超重或肥胖。在个人和生活方式特征中，外卖食品消费的高频率与非医学专业、对 HFHS 食物的高偏好、学历水平以及更高的 BMI 有关，但与体力活动无关。
结论
在中国大学生中，外卖食品的消费可能受到专业类别、对 HFHS 食物的偏好、学历水平和 BMI 的影响。这为限制高外卖食品消费提供了指导，因为高外卖食品消费会导致肥胖率升高和代谢疾病风险增加。
