| Summary: | In recent years research has shown that adolescents' body image has deteriorated and the reasons for it are thought to be various. The main purpose of this study is to look more closely at adolescents' body image and the possible effects of social media usage and physical activity on it. The Youth of Iceland 2018 questionnaire from the Icelandic Centre for Social Research and Analysis (ICRSA) was used to conduct the present study. Participants were students in 8th-10th grade in elementary school and their ages ranged from 12-17 years (M = 14.96). A random sample of 2140 participants was used in the study, 1037 females, 1085 males, and 18 participants who did not specify their gender. The results showed that there was a significant difference in body image between the genders and females had worse body image than males. They also revealed that more time spent on social media is associated with worse body image, although there does not appear to be a significant difference between the genders. They also revealed that the more time adolescents spent in physical activity, the more positive body image they had. However, there was not a significant difference between the genders.
