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

Abstract

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 (χ ² = 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.
