Obesity is a pressing health concern, the etiology for which is difficult to pinpoint given the numerous factors that can be attributed to it. On a global scale, there are currently more than 1 billion overweight adults, with at least 300 million clinically obese, and an estimated 17.6 million children under five are overweight or obese. The first aim of this study was to examine and compare the causes and rate of adiposity in faculty members and the personnel of the Islamic Azad University (IAU), maragheh branch. The second aim was to investigate the way adiposity should be controlled in these populations.In a sectional study, 155 samples were chosen randomly from among 256 faculty members and personnel of Islamic Azad University (IAU), maragheh branch. Samples went under a test to measure their subcutaneous fat and then they were asked to fill out a questionnaire designed by the researcher. Based on the data collected from the tests and questionnaires, and after an analysis done by SPSS10 software, the following hypotheses were derived: There was not meaningful relationship between age and adiposity rate and also there was not any meaningful relationship between faculty members and personnel’s age and their adiposity rate. In contrast to the above mentioned findings, there was a meaningful relationship between adiposity rate and genetic factor, and between adiposity and triple factors (physical activity, nutrition and genetics) in the faculty members of the university and its personnel.
