Abstract Background: The aim of this study was to determine the prevalence of food addiction （FA） in undergraduate students from Northwest Mexico and to examine its association with lifestyle factors, eating behaviors and food consumption. Methods: This cross-sectional study included a total of 326 undergraduate students, both sexes, between 18 and 25?years of age, who were enrolled in a bachelors degree program at a public or private university in the city of Tijuana, Baja California, Mexico. FA was assessed using the modified Yale Food Addiction Scale Version 2.0 （mYFAS 2.0）. Lifestyle （sleep patterns, physical exercise, alcohol intake, and smoking） and nutritional information （eating behaviors and food frequency consumption） was obtained through a clinical history. A multivariate logistic regression model was fitted to assess the factors associated with FA. Results: The whole prevalence of FA was 12.9%. In general, mild FA was the most frequent （5.2%）, followed by severe （4.3%） and moderate （3.4%） categories. In the multivariate model, insomnia conferred a higher risk for FA （OR = 2.08, 95% CI, 1.044.17, p?=?0.040）, while the habitual consumption of fruits showed a protective effect （OR = 0.50, 95% CI, 0.250.98, p?=?0.046）. Overall, the model predicted FA in 12% （R2=0.12, p?=?0.011）. Conclusion: The prevalence of FA is 12.9% among undergraduate students from Northwest Mexico. Although caution should be exercised, insomnia seems to increase the risk of FA, while the habitual consumption of fruits appears to have a protective role. Additional studies are needed to validate these results.
