Objective: To determine the prevalence of obesity and associated risk factors among medical students in Saudi Arabia.
Methods: The cross-sectional study was conducted from December 2012 to March 2013 at King Saud University, Riyadh, Saudi Arabia. Using stratified sampling technique, undergraduate students of either gender from the health colleges were included. Information was collected through a pretested questionnaire. Measurements of the height and weight were noted and body mass index for all the subjects was calculated.
Results: Of the 292 students, 146(50%) were males and 146(50%) were females. Obesity was found in 40(13.7%)students. It was more prevalent among males than females (p<0.05) and among those who had chronic diseases (p<0.001). Family history of obesity was significantly associated with obesity (p=0.016). No significant association was found between physical activity and obesity (p=0.863).
Conclusions: There was considerable prevalence of obesity among the medical students. Being male, having family history of obesity, and having chronic diseases were important risk factors.
