Introduction: Diet and physical activity are primary determinants of body mass index. The development of obesity involves multiple factors, such as food consumption, patterns of physical activity, social and environmental variables, and individual susceptibility determined by genetic and biological factors. However, the reasons are still incompletely understood. Thus the aim of this study was to estimate the prevalence of overweight and obesity in adults.Materials & Methods: A total of 680 participants were included in the study. The age range of the included patients was 26 to 30 years with the mean age of 28 years. Each subject s lifestyle status was assessed by a self-administered questionnaire. The overall prevalence of overweight and obesity was 20.5 and 6.8 percent, respectively. Results: body mass index had tendency to increase as fast foods, soft drink and Chips consumption and the time spent on watching TV increased and body mass index had tendency to decrease as vegetables, dairy products and fruits consumption and exercise frequency increased. Our findings indicate that there is a positive relationship between less healthy foods with body mass index and an inverse relationship between healthy foods and body mass index.Discussion & Conclusion: It was concluded that decreased time spent on watching TV was associated with lower prevalence of obesity or body fatness in children and adolescents. Viewing TV may lead to decreased energy expenditure by replacing more physically active behaviours, or to an increased energy intake as a result of food advertising, eating or between-meal snaking. TV viewing has also been suggested to lower the resting metabolic rate.
