Introduction and objectives: Body shape (BSP) and body image (BI) are part of the external physical structure, then modifications in body shape necessarily affect body image; however, both combined have not been studied. The purpose of the study was to evaluate the statistical relationship between BSP and BI in university students. Method: Two hundred and ninety-six participants (17-35 years) were included in this study. Different anthropometric measurements were used to define their somatotype (BSP), body mass index (BMI), waist to hip ratio (WHR) and waist circumference (WC). In addition, a questionnaire on body image perception was applied (McElhone et al.), regarding “how do I look?”,“how do I think others see me?”,“how do others see me?”, and “how do I want to look like?” Results: On average, men perceived themselves in normal weight; in contrast, women perceived themselves as overweight. Men were meso-en-domorphic, while women were endo-mesomorphic as an average. Conclusion: Body shape measured as somatotype as well as WC and WHR were excellent determinants of body image. Participants who presented a higher endomorphy, WC and WHR and a lower ectomorphy had a higher appreciation of being overweight or obese and wish to become thinner.
