The term body image dissatisfaction (BID) describes the negative perceptions that a person carries about his or her own body. This study aimed to determine the prevalence of BID among youth in the UAE and how it is affected by three variables: sex, age, and body mass index (BMI). Participants were 728 UAE federal university students who responded to the Body Shape Questionnaire. Results indicated that 36.7% of students are dissatisfied with their body image. Gender differences analysis showed a higher level of BID for men than with women. No significant differences were observed for BID among the four age groups. Significant differences were shown for BID among the four common BMI/weight categories (underweight, normal, overweight, obesity. On the light of the results, the study suggested offering awareness programs for youth about healthy practices in daily life and including health education in schools and colleges curriculum. The study discussed the findings in relation to the available literature in the area and suggested some directions and topics for future research.
