Community care nurses educate adolescents about body image, but their interventions appear to be ineffective. Body dissatisfaction predicts unhealthy behaviors among adolescents. This study aimed to understand the meanings and factors that influence the concept of body image through a systematic review and meta-ethnography of qualitative studies from the perspective of adolescents. Ten studies published from 2009–2019 were identified by a search of relevant systematic databases between September and December 2019. The review followed the seven steps of meta-ethnography developed by Noblit and Hare, including a line-of-argument. The synthesis revealed six themes: self-perception of body image; opinions of friends and colleagues; opinions of family; specific features of the school environment; expectations perceived across the mass-media; and strategies, practices, and self-management of body image. An explanatory model was developed that showed adolescents’ development of body image and the path towards its establishment. In conclusion, these results should be considered to implement strategies to promote a healthy body image in adolescents by community health and mental health nurses.
