山西省大学生外卖点餐相关因素及与超重肥胖的关系

  目的  了解山西省大学生外卖点餐现状及其与超重肥胖的关系，为促进大学生健康饮食和预防肥胖带来的患病风险提供参考建议。  方法  通过多阶段随机抽样的方法，对山西省大学城内的山西大学、山西理工大学、山西医科大学、山西师范大学、山西传媒学院5所高校的1 631名大学生进行问卷调查，采用有序Logistic回归分析影响大学生外卖点餐频率的影响因素，并采用二元Logistic回归分析大学生超重肥胖的影响因素。  结果  1 456名大学生有点外卖经历，性别、月均生活费、年级和专业是影响大学生外卖点餐频率的影响因素(χ2值分别为72.26，242.89，351.52，222.35，P值均 < 0.01)。大学生超重肥胖率为12.3%，其中男生为19.2%，女生为6.6%。二元Logistic回归分析结果显示，在控制性别、月均生活费、年级、专业、常住地后，大学生每周外卖点餐频率越高，超重肥胖率越高(P值均 < 0.05)。  结论  大学生外卖点餐行为比较普遍，控制外卖点餐频率有助于降低超重肥胖的发生。

Investigation of the frequency of take-out meal consumption,overweight, and obesity among college students in Shanxi Province

  Objective  This study investigated the factors influencing, take-out meal consumption among college students in Shanxi Province and explored the relationship between the frequency of take-out meal consumption and BMI.  Methods  A total of 1 631 college students from five universities in Shanxi Province were studied by means of a questionnaire and multi-stage random sampling. Logistic regression was used to analyze the factors influencing college students' take-out meal consumption. The factors influencing overweight and obesity among college students were analyzed with binary Logistic regression.  Results  A total of 1 456 college students had some take-out meal consumption. Gender average monthly cost of living, grade, and major were the factors influencing the frequency of college students' take-out meal consumption(χ2=72.26, 242.89, 351.52, 222.35, P < 0.01). The overall overweight and obesity rate among the college students were 12.3%, 19.2% in male students, and 6.6% in female students. After controlling for gender, binary Logistic regression showed that monthly cost of living, grade, major, and permanent residence influenced the frequency of college students' weekly consumption of out-of-home meals, and this led to a higher the rate of overweight and obesity(P < 0.05).  Conclusion  Take-out meal consumption is relatively common among college students, and controlling its frequency could help to reduce the occurrence of overweight and obesity.
