Abstract Objective To examine the effect of eating behavior and dietary intake on the sleep quality of college students, and to provide basis for improving students' sleep quality. Methods College students from Hangzhou Normal University were randomly selected and they were investigated from October to November, 2014. Pittsburgh Sleep Quality Index (PSQI) was used to measure the quality of sleep, and a self-designed questionnaire was used to measure eating behavior and dietary intake. Results A total of 588 college students were investigated. The average score of PSQI was 4.72±2.52, and 76 (12.9%) of the respondents have poor sleep quality. Single-factor analyses showed that sleep quality was not associated with gender, BMI, cigarette smoking and academic pressure , but was associated with peer effect, meal regularity, and frequency of fish and poultry intake (P<0.05). Multi-factor logistic regression showed that frequency of eating-out (OR= 3.04,95% CI:1.58-5.84;P= 0.001, 4 or more than 4 times vs. less than once per week) irregular dinner (OR= 1.96,95% CI:1.23-3.40;P= 0.017, irregular vs. regular) and less fish intake (OR= 2.48,95% CI:1.27 - 4.85;P= 0.01, less than once vs. 2-3 times per week) increased the risk of poor sleep quality.Conclusion Eating behavior and dietary intake are closely related to sleep quality of college students and they should concern about meal regularity and nutrition balance.
