BACKGROUND: obesity is a widespread condition with more than 400 million obese-person all over the world. It is expected of medical students to follow healthy habits as they are more familiar with the risks of obesity. In contrast, many studies showed that medical students eat fast food, spend much time on smart devices, and do not play sports. AIM: This study is the first cross-sectional study conducted to evaluate the prevalence of obesity and some daily habits carried out by medical students of Aleppo University. METHOD: The data of our cross-sectional study were collected between the 13th-20th of March 2021 through an online google form posted on different social media platforms. The questionnaire was divided into two main sections: firstly, participants' demographics (including age, gender, and academic year). In addition, medical students were asked to document their weight and height to estimate their Body Mass Index (BMI). The second section contained questions concerning daily habits including, the number of meals, breakfast, physical exercises, and fast food consumption. Chi-square and Fisher tests were performed by IBM SPSS statistics to analyze our data. RESULTS: Our sample size was 514 medical students of Aleppo University. (22.1%) of them were overweight or obese (BMI> 25). Most (73.5%) eat fast food once a week or more. In addition, (39%) have three meals or more daily, and (55.7%) have two meals every day. Regarding physical activity, (76.7%) do not play sports, and (62.1%) use buses to come to the college. Stress eaters were associated significantly(p-value<0.05) with being overweight, and (70.8%) of them had a history of being overweight (p-value<0.05). Contrary to females, we found that most males were not stressed-eaters (p-value<0.05).
